Introduction • 1-1 1 Introduction The E2 controller is a microprocessor-based control system designed to provide complete control of compres- sor groups, condensers, refrigerated cases, and other com- ponents related to refrigeration and building control. The E2 is the controlling component of a three-network config- uration (RS485 I/O, Echelon® Lonworks™ Networks, and Ethernet) that includes input and output communication boards, remote communication software, and a variety of sensors, probes, and transducers. The E2 efficiently operates all systems that support refrigeration (including compressor racks and condensers) and other components not directly related to refrigeration control, such as HVAC systems, anti-sweat heaters, and sensor control modules. 1.1 The E2 Refrigeration Controller The E2 RX is available in three models: the RX-300, RX-400, and RX-100. The E2 RX-300 is capable of con- trolling a single refrigeration system (including one con- denser and up to four suction groups). The E2 RX-400 is capable of controlling two separate refrigeration systems (including two condensers and up to four suction groups). The RX-100 is a low-cost alternative to the RX-300 with fewer capabilities and a monochrome display. The E2 RX is primarily designed to control tempera- ture and defrost in refrigerated cases using either direct control (connected to the E2 via I/O boards or ESR8 lineup control boards) or by using CC-100 case control boards (connected via the LonWorks Network).

026-1610 Rev 12 25-APR-2011 1.2 The E2 Building Con- troller The counterpart to the E2 RX is the E2 BX, which con- trols HVAC systems for low-rise retail, industrial, and commercial buildings. The BX’s primary function is to provide energy-efficient control of air handling units (AHUs), rooftop units (RTUs), and other systems related to environment control. In addition, the BX provides extensive sensor control, logging, and graphing features that allow the user to view accurate real-time information about system conditions. The BX is equipped with many power monitoring and demand control features that give you the information you need to keep your site’s energy consumption low. The E2 BX is available in two models: the BX-300 and BX-400. The only significant difference between the E2 BX-300 and the E2 BX-400 is the total number of building control devices that may be operated by a single controller. Table 1-2 shows the differences between capabilities for the BX-300 and BX-400.

Introduction • 1-3 1.3 The E2 Convenience Store Controller The CX controls HVAC, lighting, and refrigeration systems for convenience store and small-box retail facili- ties. The CX’s primary function is to provide energy-effi- cient control of rooftop units as well as refrigeration and defrost control of display cases and walk-in boxes. In addition, the CX provides extensive sensor control, log- ging, and graphing features that allow the user to view accurate real-time information about system conditions. The CX is equipped with many power monitoring and demand control features that give you the information you need to keep your site’s energy consumption low. The E2 CX is available in three models: the CX-300, CX-400, and CX-100. The only significant difference between the E2 CX-300 and the E2 CX-400 is the amount of C-Store equipment that may be operated by a single controller. The CX-100 is a low-cost alternative to the CX- 300 with fewer capabilities and a monochrome display. Table 1-3 shows the differences between capabilities for the CX-300 and CX-400.

026-1610 Rev 12 25-APR-2011 1.4 Networking Overview 1.4.1 E2 I/O Network Most of the general purpose input and output commu- nications devices required by the E2 to control refrigera- tion systems are connected to the E2 via the I/O Network. The I/O Network is a simple RS485 three-wire connection that allows data interchange between input boards (which read sensor values and digital closures), output boards (which carry out commands from E2’s control applica- tions), and the E2 itself. The I/O Network is the same thing as the COM A and COM D Networks found on Retail Solutions’ previous generation of controllers, REFLECS. This allows current owners of Retail Solutions’ Refrigeration Monitor and Control (RMC) or Refrigeration Monitor and Case Control (RMCC) controllers to easily retrofit with an E2 RX with- out need for re-wiring. Figure 1-2 shows the peripherals that make up the I/O Network: • MultiFlex - The MultiFlex line of control system boards provide a wide variety of input, output, and smart control solutions, all of which are based on a Enhanced Suction Group 0 0 4 ESR8 ESR Control 0 99 99 Flexible Combiner 64 128 128 Heat/Cool Control 4 6 8 Holiday Schedule 8 16 32 HVAC Zone 4 6 12 Infrared Leak Detec- tion 1 16 16 Irrigation 2 2 2 Lighting Control 6 24 48 Logging Group 8 32 32 Loop/Sequence Control 8 16 28 MultiFlex ESR 0 31 31 MRLDS 24 24 24 Performance Alert 0 0 63 Power Monitoring 2 8 16 Pulse Accumulator 4 8 16 RCB Controller 0 32 32 RMS Asset 99 99 99 Standard Circuit 6 12 32 Suction Group 0 0 4 TD Condenser Fan Control 8 16 28 TD3 Controller 0 99 99 Time Schedule 8 16 32 Capabilities CX- 100 CX- 300 CX- 400 Table 1-3 - CX-100, CX-300, and CX-400 Comparison Figure 1-2 - E2 RX/BX I/O Network Diagram RX E2 E2 E2 RX & BX RS485 I/O NETWORKS MultiFlex I/O MultiFlex I/O MultiFlex I/O MultiFlex I/O CS-100 CS-100 CC-100 CC-100 CC-100 MultiFlex I/O MultiFlex I/O MultiFlex I/O MultiFlex I/O

single universal hardware platform. • 8ROSMT - Relay output board - activates and deac- tivates up to eight devices. • Previous-generation I/O boards, such as 8RO, 8DO, and 4AO - are all still compatible with E2 I/O Network. 1.4.2 The E2 Echelon Lonworks Network The E2 is also compatible with a network platform called Lonworks. This is most commonly referred to as “the Echelon Network,” after the company who invented the platform, the Echelon Corporation. In general, peripherals with control functions — such as case controllers, rooftop HVAC controllers, and other E2 RX and BX units — are interconnected on the Echelon Network. These controllers do most of their own computa- tion and system control, but they communicate with other E2s to provide logging, alarm control, and other functions. In addition to these, Retail Solutions also offers Echelon- compatible input and output boards similar to those avail- able for the RS485 Network. Figure 1-3 shows the E2 RX peripherals that commu- nicate across the Echelon Network: • CC-100 - Case control board - controls all lights, fans, defrost, and refrigeration for a single case. The CC-100 controls pulse or stepper valves to provide precise evaporator control, resulting in better tem- perature maintenance and energy efficiency. • ESR8 - Evaporator stepper regulator - the analog outputs on this board allow the E2 to control circuit temperature in up to eight circuits using suction- side mounted electronic evaporator pressure regula- tors (EEPRs). • TD3 - Temperature display - has three inputs that monitor case temperature, product temperature and defrost status. • Third Party Echelon Devices - Echelon® LON- MARK® devices communicate with E2 through its "Open Echelon" networking feature, and require a license key and a description file that is loaded into the E2 that enables communication. 1.4.3 Interconnection With Other E2s In large installations where more than one refrigeration system is present, or where E2s are controlling both refrig- eration and building HVAC systems in the same site, the E2s share information with each other across either the Echelon Network or via Ethernet.

2 Hardware Overview This section gives an overview of the E2, the hard- ware, and how it communicates across the I/O and Eche- lon Networks to control an entire system. 2.1 E2 Hardware The E2 controller is programmed to monitor and com- mand all aspects of a refrigeration or building environ- mental control system. The E2 uses both an RS485 I/O Network and a LonWorks Network to gather data from input devices, communicate with other E2s, and activate or deactivate loads. In general, an E2 control network will consist of the following components: 1. E2 - The “brain” of the control network, which performs all necessary computations and sends commands to the output devices that control the system. 2. Input Boards - Transfer readings to the E2. 3. Output Boards - Banks of relays, digital pulse outputs, or analog outputs, which the E2 may use to control loads. 4. Smart Boards - Boards such as case controllers (for refrigeration) or rooftop controllers (for building control) that perform control functions for an individual case or rooftop unit, and send the data to the E2 for logging and alarm purposes. 5. Modem - For remote communication via phone, if necessary. 6. Network Wiring - Wiring that connects the E2 to other E2s, and all the input, output, and smart boards. 7. Sensors and Loads - The “eyes” and “hands” of the control network. Sensors “see” what needs to be controlled on the network, and Loads are what can be controlled, or more specifically, be turned on and off, such as compressors, condensers, lights, and fans.

026-1610 Rev 12 25-APR-2011 2.1.1 E2 Main Processor Board (CPU) The E2 CPU or main processor board (Figure 2-2) contains the CPU, Ethernet port, and memory used for log- ging. The 3.6V battery for the E2 is located on this board and protects log and alarm data during power loss. The main processor board connects to the PIB via a ribbon cable. The RX- and CX-100 versions support mono- chrome display only. For optimum viewing, backlight and contrast adjusts are available for customizing the mono- chrome display depending on the user’s needs. 2.1.2 E2 Processor Interface Board (PIB) The E2 Processor Interface Board (PIB) interfaces the power and most all communications with the main proces- sor board, and contains all field wiring connections. The PIB allows you to connect an external keyboard, accessory cards, and an external computer. All RS485 and Echelon Network connectors are located on the PIB. 2.1.3 E2 Keypad The E2 has a QWERTY style keyboard layout with two rows of function keys. The first row (-) is comprised of screen-specific function keys, and the sec- ond row has designated icon keys. The five icon keys are Help , Alarms , Home , Menu , and Back . 2.1.4 LEDs The PIB, main processor board, and keyboard (located behind the main board) LEDs can be used to determine the status of normal operating parameters for the unit.

026-1610 Rev 12 25-APR-2011 The Gateway board is an RS485 to RS485 converter. One side of the Gateway is always connected to the Retail Solutions I/O Network. The other side of the Gateway is the receiver bus (RS485). The receiver bus is connected to one or more RS485 devices depending on which type of Gateway is being used. The Gateway interfaces devices to the Einstein/E2 and legacy Retail Solutions controller (REFLECS) by simulating 16AI and 8RO boards using Retail Solutions standard I/O board protocol. The Gate- way can also convert third-party controller protocols to Retail Solutions protocol for custom cells created in the Einstein/E2 to interface with third-party controllers (Dan- foss, Woodley, etc.). The Gateway performs one of two basic functions: 1. It allows control of and/or status of a device using I/O board simulation 2. Converts a third-party protocol to Retail Solu- tions I/O Net protocol and interfaces to a custom cell in Einstein/E2 2.2.2 MultiFlex Boards The MultiFlex line of control system boards provides a wide variety of input, output, and smart control solutions, all of which are based on a single universal hardware plat- form. The board design uses flash-uploadable firmware and plug-in expansion boards to configure the base plat- form board and apply it for use as an input board, relay output board, analog output board, or a combination I/O board. 2.2.2.1 MultiFlex 16 Input Board The MultiFlex 16 input board offers sixteen combina- tion analog/digital input points for use by Retail Solutions E2, Einstein, and REFLECS control systems. The Multi- Flex 16 may be used in retrofits with no additional hard- ware or software setup or upgrades. The MultiFlex 16 is designed to be 100% compatible with the previous generation of Retail Solutions input boards (the 16AI), communicates with the site controller via an RS485 connection to a REFLECS COM A&D Net- work or an E2 I/O Network. Dip switches on the board set the network ID (board number) and baud rate. The board also provides both +5VDC and +12VDC output voltage points for use in powering transducers or other input devices that require power. The MultiFlex 16 has a Hand-held Terminal interface Section 2.2.4, Hand-held Terminal (P/N 814-3110) that may be used by technicians to view the input voltage and engineering unit values for each input point without need of a voltmeter or front panel controller display. Table 2-6 shows the part number of the MultiFlex 16.

Hardware Overview • 2-5 The MultiFlex 16 is designed with several features that make it easy to install, wire, and configure. These main user interface features are shown in Figure 2-7. 2.2.2.2 MultiFlex Combination Input/ Output Boards There are several models of the MultiFlex board that combine the functionalities of input boards, relay output boards, digital output boards, and analog output boards. The MultiFlex combination input/output boards are designed to be replacements for the 8IO Combination Input/Output Board, but the MultiFlex board provides sev- eral new hardware options and software features. The MultiFlex combination I/O boards consist of up to 16 combination digital/analog inputs, and a combina- tion of relay outputs, digital outputs, and analog outputs. All boards feature both +5VDC and +12VDC output voltage points for use in powering transducers or other input devices that require power. On the RS485 Network, the MultiFlex combination input/output boards present themselves to Einstein, E2, or REFLECS site controllers as 16AI Analog Input Boards, 8RO Relay Output Boards, 8DO Digital Output Boards, and/or 4AO Analog Output Boards, depending on what type of inputs or outputs are equipped. Dip switches are used to assign network ID numbers to each board type. The MultiFlex combination input/output boards also support a Hand-held Terminal interface, Section 2.2.4, Hand-held Terminal (P/N 814-3110) which allows tech- nicians to view input values, check relay and analog out- put states, and override output points with fixed digital or analog values. For more information on MultiFlex I/O boards, refer to the MultiFlex I/O Board Installation and Operation Manual (P/N 026-1704).

Hardware Overview • 2-7 2.2.2.3 MultiFlex CUB The MultiFlex Condensing Unit Board (CUB) is a “smart” input/output board designed to control single con- densing units. A single condensing unit is a self-contained compressor and condenser bearing unit which controls refrigeration in a single case line-up or walk-in cooler. The MultiFlex CUB uses the same general hardware configuration as a MultiFlex 168AO. It is equipped with a processor and extra memory to allow it to control com- pressors, condensers, refrigeration, and defrost for a single condensing unit using on-board I/O and control algo- rithms. The MultiFlex CUB has its own installation and opera- tion manual, (P/N 026-1706). 2.2.2.4 MultiFlex RTU (BX and CX Only) Similar in design to the MultiFlex combination input/ output boards, the MultiFlex RTU board is designed spe- cifically for operating package rooftop HVAC units as part of an E2 BX or REFLECS BCU building control system. The MultiFlex RTU is designed to be a replacement for the previous generation ARTC, and is 100% compatible with all legacy E2 BX and BCU systems. The MultiFlex RTU board has 16 analog inputs, 8 relay outputs and 4 analog outputs. Most of these I/O points are reserved for sensors and input devices required to read environmental data (such as space and supply air temperature) and control all output devices that control the environment (such as heat/cool stages and dampers). The RTU relay outputs are rated for line voltage (240VAC). The RTU board controls the rooftop unit directly with its built-in heating, cooling, and humidity control algo- rithms. It may operate in stand-alone mode, or it may interface with an E2 BX or BCU to control the store envi- ronment in zones and pass along logging and alarm infor- mation. The MultiFlex RTU has its own installation and opera- tion manual, (P/N 026-1705). 2.2.2.5 MultiFlex Rooftop Control Board (RCB) (BX and CX Only) The MultiFlex Rooftop Control Board (RCB) (P/N 810-3062) is a rooftop HVAC control board for use either as a stand-alone controller or in zone control appli- cations using a Retail Solutions E2 BX building control system. The MultiFlex RCB is capable of controlling heat and cool stages, fans, humidification and dehumidification devices, economizers using on-board I/O and control algo- rithms, as well as monitor and interact with other building control systems and peripherals (such as smoke alarms and CO2 sensors). The RCB is an improved version of the MultiFlex RTU. The RCB has sixteen fully configurable analog and digital input points, whereas the RTU has only eight inputs, two of which are configurable. The RCB has four analog outputs for use in controlling variable speed fans, economizers or modulating heating and/or cooling valves, whereas the RTU has only two analog outputs for use only with VS fans and economizers. The RCB also features a more sophisticated HHT interface and updated algorithms for controlling heating, cooling, dehumidification, and air quality. The MultiFlex RCB has its own installation and opera- tion manual, (P/N 026-1707). 2.2.2.6 MultiFlex PAK Board The PAK is a distributed pack (rack) controller that controls compressors and condenser fans. The PAK can control up to 8 compressor groups containing up to 16 compressors. The compressor control strategy is Fixed Steps with setpoint/deadband using ON and OFF delays. Up to 20 Fixed Steps can be configured.

026-1610 Rev 12 25-APR-2011 The PAK can control up to 4 condenser fan groups containing up to 8 total condenser fans. The PAK con- denser control strategy is sequential TD control with set- point/deadband using ON and OFF delays. The PAK has a compressor/condenser interlock fea- ture that will override TD control and force the condenser fans to stage off using the TD control OFF delay when all compressors are off. This feature can be disabled with an Enable/Disable setpoint or when the discharge pressure is above a configurable setpoint. The MultiFlex PAK boards consist of two circuit boards: a bottom layer with 16 combination digital/analog inputs, and a plug-in top layer which contains a combina- tion of 8 relay outputs and 4 digital DC voltage outputs. The analog outputs on the Multiflex PAK drive solid state relays to control the fan stages. The relays control the compressor groups. The communication interface is RS485 I/O using the Standard Extended Address Form for Retail Solutions Dis- tributed Controllers. Currently, the PAK is designed to interface with the Retail Solutions E2 controller. 2.2.3 The MultiFlex ESR Board The MultiFlex ESR Valve Regulator board (P/N 810- 3199), shown in Figure 2-1, is an RS485 I/O Network electronic stepper valve regulator capable of driving up to eight stepper motor valves, which are typically used to control temperature. The MultiFlex ESR uses suction side variable-position evaporator regulators (ESRs) to vary evaporator pressure for an entire circuit and is an alternative to mechanical EPR control. The MultiFlex ESR receives input data from a Retail Solutions E2 controller (via the I/O Network) and then regulates the stepper valves according to the data from the E2. Each MultiFlex ESR board requires a Class 2, 80VA 24VAC center-tapped transformer for power. Retail Solu- tions transformer (P/N 640-0080) is a multi-tapped pri- mary transformer that may be used with the MultiFlex ESR board. 2.2.4 Hand-held Terminal (P/N 814-3110) The Hand-held Terminal (HHT) is used by manufac- turers and service technicians to diagnose and test several of Retail Solutions' existing and legacy products. The HHT can be used on any Retail Solutions product with an RJ-11 connector. The most common applications include: • All MultiFlex I/O boards and the 8ROSMT • All Gateway boards • Stand-alone MultiFlex boards (RTU, RCB, PAK, CUB) LEGEND 1 INPUT POWER (24VAC) 9 RS485 TERMINATION JUMPERS 2 RS485 I/O NETWORK 10 HAND-HELD TERMINAL JACK 3 PAK INPUTS 1-8 11 RELAY OUTPUT CONNECTORS 4 PAK INPUTS 9-16 12 RELAY OUTPUT FUSES (2A rated, 250V slow- blow) 5 NETWORK ID DIP SWITCH (S3) 13 RELAY STATUS LEDs 6 INPUT TYPE DIP SWITCHES (S1, S2) 14 RELAY FAIL-SAFE SWITCHES 7 BOARD STATUS LEDs (Code A, Code B, General Status) 15 PAK ANALOG OUTPUTS 1-4 8 DC POWER OUTPUTS (3 at +5VDC, 1 at +12VDC) 16 NETWORK STATUS LEDs Table 2-9 - MultiFlex PAK Figure 2-1 - MultiFlex ESR Board Layout 8 3 7 24VAC CT 75 VAC Power Input Valve Connectors (8) I/O Network Input Termination Jumpers Network Address Switches General Status LED 1 5 2 3 4 6 7 8 HHT Jack TX and RX LEDs 9 10 Open LED (8) Close LED (8) 9 10

Hardware Overview • 2-9 • CCB and CC-100 case controllers The HHT does not require a separate power source. The unit is powered from the RJ-11 connector on the peripheral equipment. The HHT includes a standard male RJ-11 to male RJ-11 cable. 2.2.5 The 8RO and 8ROSMT Relay Boards The 8RO (P/N 810-3005) board is a general-purpose board used to connect an E2 to any of eight standard con- trol relay outputs, but is now obsolete and has been replaced by the 8ROSMT (P/N 810-3006) board. To function, the 8RO board must be connected through either the Echelon Network or the RS485 I/O Network to the E2. When properly installed, the 8RO receives an elec- trical impulse from the E2, which either opens or closes any of eight contact relays. Output definitions within the E2 allow the user to configure the 8RO board to interact with any refrigeration system or environmental control component. The 8RO board is the direct link between the E2 and component operation. Information gathered by the con- troller from the input boards is checked against current stored setpoints. If differences in the received input data and the setpoint information are detected, a signal is either sent to the proper 8RO relay, or an existing signal is dis- continued. Through the use of this relay signal, control functions that can be properly maintained by a simple con- tact closure sequence are effectively operated by the E2. The 8RO board is easily installed and operated within the Retail Solutions Network environment because of its straightforward design. Several of these features are shown in Figure 2-11. NOTE: The 9V battery and 9-12V DC adapter connection are not used on this HHT model (P/N 814-3110).

026-1610 Rev 12 25-APR-2011 2.2.6 4AO Analog Output Board The 4AO Analog Output Board (P/N 815-3030) (Fig- ure 2-13) is configured with four analog output connec- tions that provide a variable voltage signal to any of four analog devices that may be controlled by a single E2. Two 4-20mA outputs are provided for channels 1 and 2. The 4-20mA outputs provide a variable current for applications that are either externally powered or that require power from the 4AO board. The previous generation 4AO Analog Output Board, (P/N 810-3030) (Figure 2-14) is configured with four ana- log output connections that provide a variable voltage sig- nal to any of four analog devices that may be controlled by a single E2. 2.2.7 8DO Digital Output Board and PMAC II Anti-Sweat Controller For control of anti-sweat heaters, Retail Solutions sup- plies the 8DO Digital Output board (P/N 810-3050). The 8DO has eight outputs which may pulse up to 150mA at 12VDC. Since the 8DO is primarily designed to control anti- sweat heaters, the 8DO is the heart of Retail Solutions’ Pulse Modulated Anti-Sweat Control (PMAC II) panel. The PMAC II (P/N 851-1000) provides 16 channels of anti-sweat control circuitry. The PMAC II panel combines the 8DO with high-capacity relays in a single enclosure, providing 256 total amps of anti-sweat heater operation. The 8DO is shown in Figure 2-15. The PMAC II is shown in Figure 2-16.

Hardware Overview • 2-11 2.3 Echelon Network Boards and Peripherals 2.3.1 The 16AIe (Discontinued) The 16AIe (P/N 810-4000) is an Echelon-based input board similar in function to its I/O Network counterpart, the MultiFlex 16 (see Section 2.2.2). The 16AIe receives input signals through any of 16 two-wire connections. The board receives either digital or analog data from sensors wired to any of the 16 input connections located on the board. This board has been discontinued and is no longer available for sale. 2.3.2 The 8ROe (Discontinued) The 8ROe (P/N 810-4010) is an Echelon-based input board similar in function to its I/O Network counterpart, the 8RO. The 8ROe board is the direct link between the E2 and component operation. Information gathered by the controller from the input boards is checked against current stored setpoints. If differences in the received input data and the setpoint information are detected, a signal is either sent to the proper 8ROe relay, or an existing signal is dis- continued. Through the use of this relay signal, control functions that can be properly maintained by a simple con- tact closure sequence are effectively operated by the E2. The 8ROe features Form C contacts for wiring outputs as either normally open or normally closed. Fail-safe dip switches on the 8ROe allow the installation technician to specify the desired state of each relay in case of communi- cations loss. This board has been discontinued and is no longer available for sale. 2.3.3 EC-2s The EC-2 is an advanced refrigerated case controller that doubles as a temperature and case status indicator. During refrigeration and defrost, the EC-2 controls most typical case functions, including fans, defrost, and a pulse valve on the liquid side of the evaporator to regulate super- heat. The EC-2 29x version controls the refrigeration sole- noid valve to allow the passage of refrigerant to the TXV valve. The EC-2 39x version controls a pulse valve on the liquid side of the evaporator to regulate Superheat control. The EC-2 relies on a parent E2 to handle logging, alarm control, defrost scheduling, and other case control functions. The EC-2 is designed to be mounted on the front of a refrigerated case. The LED display shows the current case temperature with one-tenths of a degree's accuracy. The display can also show alarm codes to immediately notify Figure 2-17 - 16AIe Figure 2-18 - 8ROe Figure 2-19 - EC-2

026-1610 Rev 12 25-APR-2011 floor managers of alarms and notices. Other lights on the display show the ON/OFF status of refrigeration, defrost, and fans. The EC-2 can be easily programmed using either the four front-panel buttons or an optional infrared remote control. For security, the buttons can be disabled to pre- vent tampering. 2.3.4 CC-100 Case Controllers and CS-100 Case Circuit Controllers A CC-100 case control board is a “smart” board capa- ble of controlling all functions for a single case, including lights, fans, defrost, anti-sweat, and suction side or liquid side valve control. CC-100s perform these functions inde- pendently from the E2 RX controllers, but it does rely on a parent E2 for logging, alarming, providing supplemental I/ O values, and coordinating defrost times among circuits. There are four different models of the CC-100, each of which controls a different type of valve. 1. CC-100P (P/N 810-3160)— Case controller for liquid-side pulse valves (also called electronic expansion valves, or EEVs). This model is capa- ble of controlling up to two pulse valves simulta- neously (for use in dual-evaporator applications such as walk-in boxes). 2. CC-100LS (P/N 810-3170) — Case controller for liquid-side stepper valves (EEVs). 3. CS-100 (P/N 810-3177) — Case circuit controller for suction-side stepper valves (also called elec- tronic evaporator pressure regulators, or EEPRs). 4. CC-100H (P/N 810-3171)— A special version of the CC-100 that is used by a particular manufac- turer. This board controls temperature in a case using suction-side stepper valves that regulate pressure in the evaporator. The CC-100/CS-100 board is shown in Figure 2-20. 2.3.5 The ESR8 (Discontinued) The ESR8 electronic suction regulator (P/N 810-3195) is an Echelon Network-based control board that controls up to eight separate electronic suction regulator (ESR) stepper valves. The ESR8 uses suction-side variable posi- tion ESRs to vary evaporator pressure and control temper- ature for an entire circuit. The ESR8 offers an economical, more efficient alternative to TXV control. The board can be used with either Emerson Flow Con- trols ESR12 or ESR20 valves as well as a number of com- mercially available ESR stepper valves. Note that Emerson Flow Controls supplies both a 24 Volt and a 12 Volt version of the valve. The ESR board is only compati- ble with the 12 Volt version of the valve. The board features two LEDs for each valve which indicate movement and direction. A status LED indicates the general status of the board. The ESR8 board is shown in Figure 2-21. NOTE: There are several variations of the EC-2. Contact Retail Solutions at 1-800-829- 2724 for more information. Figure 2-20 - Case Controller (CC-100P shown)

Hardware Overview • 2-13 2.3.6 TD3 Temperature Display The TD3 is a digital display unit designed to show both case temperature and product temperature for a refriger- ated store case or walk-in freezer. The TD3 mounts on the front of a case and connects to up to three input devices (a case temperature sensor, a product temperature probe, and either a defrost termination probe or thermostat). The real- time input values of these probes can be viewed on the TD3’s digital display by pressing the function button on the front panel to cycle through the temperatures. The TD3 is connected to a central E2 RX controller via the Echelon Network. Input values are sent to the E2 from the TD3 for use in case circuit control. A diagram of the TD3 layout is shown in Figure 2-22. 2.3.7 Facility Status Display (FSD) The FSD reports alarm information and more, (such as temperatures, occupancy, case status, and setpoints) and provides a centralized device for store personnel to review information by communicating with the E2 via Ethernet connectivity (minimum E2 firmware rev. 2.68F01). The FSD has a touch screen color display for quick navigation and can be mounted in a separate, remote loca- tion from the E2 controller, which enables alarms and other relevant store information to be viewed from where it is most convenient for the user. The FSD can be configured to filter out notices and/or return-to-normal alarms, and provides a quick review of all advisories and detailed advisory information. The FSD also receives alerts and provides annunciated alarms and alarm information directly to store and department manag- ers. This compact unit can be installed virtually anywhere with a standard Ethernet connection and 120V power source. If more than one E2 controller is at a site, one E2 must be set up as the alarm annunciator for that site. The FSD will receive alarms from that alarm-annunciator E2 for the entire site. The FSD will point only to a single E2 at a site (it will not poll multiple controllers for alarms). For more information, refer to the FSD Manual (P/N 026-1400).

Mounting • 3-1 3 Mounting This section gives mounting instructions and dimen- sions for all controllers and peripherals in the E2 system. 3.1 Mounting the E2 The E2’s box body style is designed to be mounted against or inside a wall or panel. If mounted against a sur- face, the controller will be 3.75” off the mounting surface. If mounted inside a surface, the door and front section of the back panel will rest 2.0” off the mounting surface. See Figure 3-1, and Figure 3-2. 3.1.1 Standard Mount The standard mount is meant for the controller to be mounted against a wall using the four mounting holes at the rear of the enclosure shown in Figure 3-3. These holes are accessible without any removal of boards inside the enclosure. 3.1.2 Recessed Mount The recessed mount is meant for the controller to be bolted against a surface using the eight mounting holes. The unit may be mounted with the recessed back portion of the unit inside the wall, and the front portion of the unit visible through the hole in the wall (Figure 3-1 and Fig- ure 3-4). For a recessed mount, you will need to cut a rectangu- lar hole into the mounting surface 9.0” wide by 10.5” high (22.86 cm wide by 26.67 cm high). Once this hole is cut, mount the unit as desired using the eight outer mounting holes shown in Figure 3-1 and Figure 3-4.

026-1610 Rev 12 25-APR-2011 3.1.3 Retrofit Mounting The retrofit mounting plate and bracket allow the E2 to be mounted where previous generation controllers (Ein- stein or REFLECS) were. These two options allow con- version of the flush-mounted Einstein and the side- mounted REFLECS. Figure 3-5 shows the low-profile conversion mount plate that allows a flush-mounted Einstein to be converted to a low-profile mount. The plate slides over the back of the E2 and is attached using the four holes pictured closest to the cut out (four screws and four nuts are included), but the plate is equipped with a total of 14 holes for the best possible fit. Figure 3-6 shows the conversion bracket that allows a side-mounted REFLECS to be converted to a side- mounted E2. The conversion bracket is attached to the back of the E2 using the two holes at the top and bottom of the bracket, and aligning the oval openings with the oval cut-outs in the back of the E2 case. Once the E2 is attached to the conversion bracket, use the two holes in either side of the conversion bracket (depending on which side is needed) to mount the E2 to the wall and replace the REFLECS controller.

Mounting • 3-3 3.1.4 Blank Face Blank face control is designed to be used in a system with more than one E2. It has no screen or keyboard and is logged into remotely from another E2 on the Echelon net- work. The green General Status LED transmits status information to the user. See Table 2-3 on page 2-3 for more information on main board (CPU) status LEDs. Blank face mounting dimensions are identical to the stan- dard and recessed mount boxes. See Figure 3-3 and Fig- ure 3-4. 3.2 Mounting I/O Boards The 16AI, 8RO, 8DO, 4AO, 8IO, and MultiFlex boards are usually installed by the refrigeration or building equipment manufacturer. Therefore, the installer need only make the necessary connections between the E2 and the cases, condenser boards, and/or HVAC units. In some instances, an installer may be required to mount an I/O board. There are no restrictions on the loca- tion of these boards; however, for ease of network config- uration, it is recommended that the boards be located adjacent to the E2. I/O boards may be mounted without an enclosure, but they should be mounted in a location that is not easily accessible to avoid tampering or damage. 3.2.1 Single/Double Enclosures The Single enclosure and Double enclosure are sup- plied with four mounting holes in the rear panel of the enclosure. The mounting holes can be accessed without removing any of the boards inside the enclosure. Figure 3- 7 shows the dimensions and weight for the Single enclo- sure. Figure 3-8 shows mounting dimensions for the Dou- ble enclosure. When mounting boards inside the enclosure, refer to Figure 3-9 for mounting dimensions for the MultiFlex, 16AI, 8RO, and the 8DO.

026-1610 Rev 12 25-APR-2011 3.2.2 Boards Without Enclosures (Snap Track) 16AI, 8RO, 8DO, and Gateway boards not supplied with an enclosure are supplied with a snap-track for easy installation. The insulation sheet and I/O board must be removed from the track before the track is mounted. The snap-track is mounted using the 0.1875” mounting slots. Figure 3-10 shows this installation procedure. Figure 3-9 provides mounting dimensions for the Mul- tiFlex, 16AI, 8RO, and the 8DO boards. Figure 3-11 pro- vides mounting dimensions for the 4AO. The Gateway is typically mounted in the same area as the site controller, near the controller’s 16AI, 8RO, and other RS485 Network peripherals. The Gateway is designed to fit into a standard 3" snap track (supplied with the board) or may be mounted in a panel or on stand-offs. Follow the dimensions in Figure 3-12 for panel mounting. The Gateway should be mounted in an environment with ambient temperature between -40°F and 150°F, with a non-condensing relative humidity between 5% and 95%. 3.3 Echelon Devices 3.3.1 16AIe and 8ROe The 16AIe and 8ROe boards have the same mounting dimensions as their I/O counterparts, the 16AI and 8RO boards.

Mounting • 3-5 3.3.2 CC-100 Case Controller and CS-100 Case Circuit Controller Generally, the case controller will be mounted within the raceway or on top of the case. If a controller must be replaced or installed in the field, it should be located based on the specific design of the case. 3.3.3 ESR8 (Discontinued) The ESR8 board is slightly larger than the 16AI and 8RO boards, and is not supplied with a snap-track. If the ESR8 is supplied without an enclosure, it is supplied with 0.500” long metal stand-off dowels which are pressed into the mounting holes in the board (See Figure 3-14). 3.3.4 MultiFlex ESR The MultiFlex ESR is supplied with a snap-track. If the ESR8 is supplied without an enclosure, it is supplied with 0.500” long metal stand-off dowels that are pressed into the mounting holes in the board. 3.3.5 TD3 The TD3 temperature display is almost always mounted by the OEM as part of the construction of the refrigerated cases. As such, field installations of TD3s are rare. TD3s are typically flush mounted on the front of a refrigerated case in such a way as to be fully visible from the sales floor. A hole one inch in diameter must be drilled into the case to allow the TD3’s wiring harness to extend into the case and connect to the network, the power source, and the case-mounted probes. Figure 3-16 shows the mounting dimensions of the TD3. 3.4 Modem/Communica- tion Expansion Card Mount- ing (New Processor Board) The E2’s modem/communication expansion card mounts above the PIB in the back of the enclosure box as shown in Figure 3-17. The standoffs and mounting holes are located above the PIB in the back of the enclosure box. Use the mounting screws and standoffs to secure the card in place. The ribbon cable plugs into the "Modem/Com 6" slot on the motherboard.

Disconnect power to the unit, and carefully plug the male pins on the back of the modem card into the E2’s PC- 104 slot. Use the standoffs and screws supplied with the modem card to secure the card to the main board, as shown in Figure 3-18. When finished, restore power to the E2. 3.4.2 Two-Channel and Four- Channel Repeaters 3.4.2.1 Mounting Repeaters Overview Repeaters are used to extend the maximum length of a segment of Echelon cable, or to act as a bridge between two devices that are farther apart than the cable’s maxi- mum node-to-node distance. Retail Solutions offers two versions of repeaters for the E2 controller: an external two-way repeater that comes in an enclosure (P/N 832- 1010), and a four-channel repeater mounted in the E2 (P/N 832-4830). For more information about installing repeaters and routers, please refer to the Repeater and Router Installa- tion and Networking Guide (P/N 026-1605). 3.4.2.2 Mounting the Two-Channel Repeater The external repeater (P/N 832-1010) is externally mounted within its own enclosure. Figure 3-17 - Modem/Comm Card Mounting in E2 NOTE: Because the modem/communication expansion card and four-channel repeater card share the same mounting platform, they must be used separately. CAUTION: Power down the E2 before plug- ging the modem into the PC-104 slot. Failure to do so can damage the modem and void the warranty. Figure 3-18 - Mounting the Internal Modem Board

Mounting • 3-7 For external repeaters, the mounting bracket at the bot- tom of the enclosure has two 0.156” bolt holes on either side. Use the bolt holes to mount these repeaters in the field as necessary (see Figure 3-19). When mounting external repeaters, keep in mind that they require a 24VAC Class 2 power source in order to operate. This will likely require a transformer such as P/N 640-0041 (110V) or P/N 640-0042 (220V) to be mounted near the external repeater enclosure. Make sure there will be enough space next to the repeater to mount the trans- former. 3.4.2.3 Mounting the Four-Channel Repeater The four-channel repeater (P/N 832-4830) serves the same basic function as the two-channel repeater: boosting signal strength. However, the four-channel repeater is also useful as a means of connecting the E2 to its associated devices using more than one daisy chain. With a four-channel repeater mounted in the E2, you can run as many as three daisy chain segments out into the field, each of which can be as long as the prescribed Eche- lon maximum wire length. The fourth channel of the repeater can be used to connect other E2s in a separate daisy-chain, eliminating the need to run cable from the field back to the next E2. The standoffs and mounting holes are located above the PIB in the back of the enclosure box. Use the mounting screws and standoffs to secure the four-channel repeater in place, and connect the repeater to the PIB with the two-pin power connector located next to the battery. 3.5 Sensors and Transduc- ers 3.5.1 Pressure Transducers Retail Solutions transducers convert pressure readings to proportional electrical signals between 0.5 and 4.5 volts. The transducer is designed with a 1/8-inch male FPT fitting for connection to a standard access fitting. If the fit- ting is configured with a Schrader valve, this fitting will have to be removed and replaced with a 1/8-inch female fitting. Each pressure transducer is supplied with 20 feet of cable for connection to a 16AI input board. 3.5.1.1 Mounting The pressure transducers should be mounted in a verti- cal position (pressure port down) above crank case oil level to prevent drainage of oil into transducer port. 3.5.2 Inside Temperature Sensor 3.5.2.1 Location Inside temperature sensors are supplied within a wall- mounted enclosure for attachment to a standard switch plate. The temperature sensor should be located in a central location—within the zone to be measured—away from doors, windows, vents, heaters, and outside walls that could affect temperature readings. In addition, the sensor Figure 3-19 - External Repeater Mounting NOTE: Because the modem/communication expansion card and four-channel repeater card share the same mounting platform, they must be used separately.

026-1610 Rev 12 25-APR-2011 should not be mounted above other sensors that generate heat during operation (such as relative humidity sensors). The indoor temperature sensor should be between four and six feet from the floor. 3.5.2.2 Mounting Mount the sensor using the screws provided as shown in Figure 3-21. 3.5.3 Outside Temperature Sen- sor 3.5.3.1 Location The outside or ambient temperature sensor should be located on the north side of the building, preferably under an eave to prevent sun-heated air from affecting the tem- perature of the sensor. 3.5.3.2 Mounting The temperature sensor may be mounted using any standard tubing clamp. Retail Solutions also offers an alu- minum cover and clamp (P/N 303-1111) which may be mounted as shown in Figure 3-22 (fasteners are not pro- vided). 3.5.4 Insertion Temperature Probe 3.5.4.1 Location The 12-inch insertion temperature probe may be used to monitor temperature in either the supply or return air ducts of the AHU or RTU. 3.5.4.2 Mounting The insertion probe may be mounted in any orientation within the duct as long as the probe is in the air flow of the duct. The probe housing should be secured using self-tap- ping screws. A 0.250” diameter hole is required for the probe. Figure 3-23 shows the installation of the insertion probe (self-tapping screws are not provided). 3.5.5 Supply and Return Air Sen- sors In addition to the 12-inch insertion temperature probe, Retail Solutions uses the same temperature sensor used for Figure 3-21 - Inside Temperature Sensor Mounting Figure 3-22 - Outside Temperature Sensor with Cover and Clamp Figure 3-23 - 12-Inch Insertion Probe Mounting

Mounting • 3-9 outside and inside temperature to monitor supply and return air temperature. When used in this application, the sensors are supplied without enclosure covers. The sensors should be mounted directly in the air stream of the supply or return air duct. The sensors are not supplied with any mounting hardware for this application. 3.5.6 Refrigeration System Tem- perature Probes and Sensors 3.5.6.1 Location Retail Solutions supplies several temperature monitor- ing devices including bullet sensors, pipe mount sensors, immersion probes, insertion probes, and sensors for high temperature applications. Each of these sensors is gener- ally installed on the system by the equipment manufac- turer. If a device must be added to the system, refer to the information supplied with the device and consult the refrigeration equipment manufacturer. Table 3-1 lists some typical sensor applications and the sensor or probe most suited for that purpose. 3.5.6.2 Mounting Bullet and Pipe Mount Sensors Bullet or pipe mount sensors mounted on refrigerant lines should be secured with a Panduit low temperature cable tie, number PLT2S-M120, or equivalent. For pipe mount sensors, the curved surface should be placed against the pipe and the tie should be positioned in the groove on the top surface of the sensor. A second tie should be used to secure the lead to the pipe for additional support. Sensors located on refrigerant lines should be insulated to eliminate the influence of the surrounding air. A self- adhering insulation that will not absorb moisture is recom- mended to prevent ice logging at the sensor location. The sensor should be positioned on the side of the line as shown in Figure 3-24. 3.5.7 Product Temperature Probes The product temperature probe is designed to be used alongside food products in a refrigeration case or freezer. The product probe uses a thermistor type temperature sen- sor in a sealed, cylindrical container (approximately 16 oz.). A magnet is contained at the bottom the probe’s enclosure to allow easy attachment to a side or bottom of a refrigeration case. 3.5.8 Humidity Sensors and Humidistats 3.5.8.1 Indoor RH Sensor The indoor relative humidity sensor should be mounted in a central location within the zone to be mea- sured, away from doors, windows, vents, heaters, and out- side walls that could affect temperature readings. The sensor should be between four and six feet from the floor. Note that this sensor generates a small amount of heat; therefore, do not mount temperature sensors directly above RH sensors. Mount RH sensor (P/N 203-5751) as follows: 1. With a flat-head screwdriver, push down the middle tab on the top of the sensor case and pop the lid off to expose the circuit board. 2. Insert the flat-head screwdriver into the two slots on either side of the top of the sensor case and twist to separate the back plate from the case. 3. Remove the knock-outs from the back plate before mounting so wires may be threaded through.

Replace the cover on top of the back plate by lining up the tabs, and snap the lid back into place. 3.5.8.2 Outdoor RH Sensors The outdoor RH sensor (P/N 203-5761) The outdoor RH sensor (P/N 203-5761) should always be mounted on the north side of the building if in the Northern Hemisphere, or on the south side if in the South- ern Hemisphere. The sensor should be mounted under an overhang or otherwise out of direct sunlight (if possible). Mount the RH sensor (P/N 203-5761) as follows: 1. Secure the rear side of the enclosure to the out- side wall using the two mounting brackets, as shown in Figure 3-26. The tube holding the sen- sor element should point straight down. 2. If you will be running the sensor cable through the wall behind the sensor, cut or drill a hole in the wall through the hole in the enclosure. 3.5.8.3 Duct-mounted Insertion RH Probe Retail Solutions specs a duct-mounted relative humid- ity (RH) sensor (P/N 203-5771) with a 0-5VDC output for use in building control and anti-sweat control applications using Retail Solutions input boards. 1. Cut a small circular hole in the duct large enough for the sensor tube to fit through. 2. Bolt the sensor enclosure against the outside of the duct wall so that the sensor element fits through the hole and into the duct. The enclosure may be mounted horizontally, as shown in Fig- ure 3-27 or vertically. The screws should be tight enough for the foam gasket around the bottom of the sensor to form an airtight seal between the hole in the duct wall and the outside air.

026-1610 Rev 12 25-APR-2011 4.1.3 Main Processor Board (Pre- vious Version) 4.1.4 Power Interface Board The PIB interfaces the power and most all communica- tions with the main board, and contains all field wiring connections. 4.2 Powering the E2 Starting at the lower right side of the PIB, the first plug is the 24VAC input. This must terminate into the power supply transformer. E2 requires 24VAC Class 2 power, which is supplied by a non-center-tapped Class 2 transformer. Retail Solutions supplies two transformers that may be used to power E2s: one for use with 110VAC (P/N 640- 0041), and one for use with 220VAC (P/N 640-0042). Both transformers are rated at 50VA, and each will power one E2 unit. 4.2.1 RS485 Ports On the lower left side of the PIB are two RS485 Net- work connector ports. This is where all I/O boards (except the case controllers, TD3, ESR8, and Echelon I/O boards) are connected. 4.2.2 RS485 Jumpers There is one set of RS485 jumpers for each RS485 port. Jumpers JP1-3 are located directly above the first connector port, and jumpers JP4-6 are located directly above the second connector port. The RS485 termination jumpers (JP1, JP2, JP3, JP4, JP5, and JP6) are used to ter- minate the devices at the beginning and end of an RS485 Network. If the E2 is the beginning of all RS485 I/O Networks, all three of these jumpers should be set to the UP position. 4.2.3 Echelon Network Connect The next connector is the Echelon Network plug. The one connector handles both input and output connections. The input and output cables are connected directly to the Echelon plug. This plug is the connection to the Case Con- troller (CC-100), the Evaporator Stepper Regulator board (ESR8), TD3s, and other E2s. 4.2.4 Echelon Jumpers The two Echelon jumpers (JP7 and JP8) are located next to the Echelon Network port. Additional information about Echelon Networking and terminating the network can be found in Section 8.3, Ech- elon Network Structuring (Daisy-Chains).

All Echelon devices are wired together using the daisy-chain method of network structuring. For the E2 to communicate on the Echelon Network, the plug-in card must be connected. No Echelon Network communication can occur without the card. The plug-in Echelon card connects to the main proces- sor board on the far right side of the board just above the Power Interface Board (PIB) connector. The connector for the plug-in Echelon card is labeled Echelon Plug-In so it is easy to find. Figure 4-5 - Echelon Card

This optional card adds a second RS485 port (COM4) to the E2, allowing a connection to the ISD compressors, Control Link devices, and other supported MODBUS devices. The plug-in RS485 Network card connects to the power interface board between the two fixed RS485 I/O Network connectors and the battery. 4.3.5.1 LEDs The plug-in RS485 Network card LEDs can be used to determine the status of normal operating parameters for the card. 4.3.6 Plug-In Four-Channel Inter- nal Repeater The four-channel repeater (P/N 832-4830) boosts sig- nal strength on Echelon Networks. However, the four- channel repeater is also useful as a means of connecting the E2 to its associated devices using more than one daisy chain. With a four-channel repeater mounted in the E2, you can run as many as three daisy chain segments out into the field, each of which can be as long as the prescribed Eche- lon maximum wire length. The fourth channel of the repeater can be used to connect other E2s in a separate daisy-chain, eliminating the need to run cable from the field back to the next E2. The plug-in Four Channel Internal Repeater card con- nects above the power interface board on the case mounts using standoffs and screws. See Section 3.4.2.3, Mounting the Four-Channel Repeater for more information. 4.4 Battery Testing and Replacement The 3.6V battery located on the E2 processor board protects log and alarm data during power loss.

5 Serial Configura- tion 5.1 Overview E2’s Serial Configuration is the centralized location where all communication ports (COM ports) may be set up in the E2 controller. To support the increasing number of third-party devices that E2 can communicate with, E2 has the expanded flexibility of dynamic COM ports that will support different types of communication protocols to meet the specific needs of the user. Previously, all COM ports were pre-defined to support a specific type of serial device. E2 now has five configu- rable COM ports that can communicate with different devices on the network. 5.2 COM Ports The Serial Connection Manager is located in General Setup under the Serial tab. To access Serial connections to set up the COM ports, press Alt + M, or from the E2 Main Menu: 1.  - System Configuration 2.  - System Information 3.  - General Controller Info 4. C3: Serial tab To begin, first select the COM port you wish to set up, choose the protocol, and set the baud rate. The user associates the various hardware devices with the COM ports listed under the Serial tab. Five COM ports have user-configurable values such as baud rate and con- nection type settings. Pre-Sets COM1 is pre-set for serial connection. COM3 is pre- set with a modem-only connection type. The COM5 con- nection is a non-configurable E2 keyboard port. 5.3 Serial Device and Soft- ware Setup After the COM card has been connected to the E2, set up the associated COM port in the Serial Connection Man- ager: Figure 5-1 - Serial Configuration Screen NOTE: If a COM card is not connected to the E2, its associated COM port will not be visible in the Serial Configuration screen.

These devices are connected via the RS485 connectors (for wiring convenience, two connectors are available) on the PIB. The connection type and baud rate are configurable. COM3 COM3 is a pre-set connection type for modems only (optional). The E2 modem/expansion communication card (P/N 637-4871) has a plug-in modem that uses the phone line jack (RJ- 11). The 637-4872 version has a plug-in for an external modem. Configure the baud rate and modem type for either the internal modem or the external modem. COM4 COM4 is located on the optional RS485 COM card for configurable devices. Configure COM4 to the type of device you are connecting: I/O Net, ISD 1.0 (RX unit default), IMC/ Prodigy (BX/CX unit default), or MODBUS 1-3. The RS485 COM card is connected above the COM2 dual RS485 connectors on the PIB. The connection type is configurable. COM6 COM6 is located on E2's optional modem/expansion communication card, which can be configured for RS485 operation. Configure COM6 to the type of device you are connecting: I/O Net, ISD 1.0 (RX unit default), IMC/Prodigy (BX/CX unit default), or MODBUS 1-3. (RS232 operation will be available in future versions of E2.) Both connectors cannot be used at the same time. Configure the connection type, baud rate, and parity.

The RS485 Network and Hardware Setup • 6-1 6 The RS485 Network and Hardware Setup Previous versions of E2 hardware and firmware before version 2.30F01 only supported one I/O network port, with an optional expansion card that could be used for connection to Copeland ISD compressors or IMC/Prodigy S-Bus rooftop unit controllers. Beginning with E2 version 2.30F01, E2s now have up to three RS485 network ports, each of which may be configured as an I/O network, IMC/ Prodigy, ISD, or ECT MODBUS port. Section 5, Serial Configuration of this manual covers how to assign COM ports COM2, COM4, and COM6 to different RS485 network types. Section 6 (this section) explains the network types, the hardware that may be con- nected to each type, and how to configure the devices. 6.1 The I/O Network All boards and controllers manufactured by Retail Solutions for communication with E2 via RS485 are gen- erally referred to as I/O boards, and the network they are connected to is referred to as the I/O network (or I/O Net). A COM port configured as I/O Net may connect with up to 127 I/O boards. This network is used by the E2 to read data from the input boards and to send commands to the analog and digital output boards. Some unit control- lers, such as CCB case controllers and MultiFlex RCBs, also communicate with the E2 via the I/O Network. 6.1.1 I/O Board Names and Termi- nology There are many input, relay output, analog output, and combination I/O boards available from Retail Solutions for use with the E2. However, separate from the various MultiFlex unit controller models, E2 only recognizes four different types of I/O boards: 16AI, 8RO, 4AO, and 8DO. All E2-compatible I/O boards communicate with E2 as if they are one or more of these types of boards. In this manual and in the E2 interface, when you encounter these board names, bear in mind that they are terms that represent many types of boards. Table 6-1 describes all the actual boards or board components for each E2 “board type.” Board Type Max # Translation Boards That Match Board Type 16AI 16 Any I/O board that has digital and ana- log inputs.

026-1610 Rev 12 25-APR-2011 6.1.2 MultiFlex-Plus (+) Board The MultiFlex-plus board contains a replacement RS485 transceiver chip that presents less of a load on the network than a non-plus board. This increases the maxi- mum number of devices that can be placed on the network, but not the number of board types an Einstein controller can communicate with. The MultiFlex-plus board now accounts for only 1/8 the load of a non-plus board with 32 total devices on the network (one Einstein controller + 31 boards). This new conversion allows for the placement of 256 devices on the network (one Einstein controller + 255 boards). The num- ber of boards an Einstein controller can support is increased from 31 up to 255 using MultiFlex-plus boards only. In other words, the number of I/O net devices are no longer restricted by the I/O net 31-node limitation. 6.1.2.1 Board Designation Plus boards are always identified with a plus (+) sign that appears on the plastic insulating cover on the top of the board, after the board name. 6.1.2.2 Board Calculations With X as the number of plus boards and Y as the num- ber of non-plus boards, use the following equation to ensure that the number of devices on your network has not exceeded the maximum load limitation of the network. For example, if the total number of devices is less than 256, the maximum load limitation has not been exceeded. 6.1.3 Wiring Types Retail Solutions specifies all RS485 I/O and MOD- BUS wiring used by the E2 must be Belden 8641 (24AWG, 300V, Retail Solutions P/N 135-8641); Belden 8761 (22 AWG, 300V not stocked by Retail Solutions); or a 600V-shielded 22AWG equivalent stocked by Retail Solutions (P/N 135-0600). These are two-connector shielded twisted pair cables that support a maximum daisy chain cable distance of 4000 feet (1219 m) between the E2 and the end device on the network. 6.1.4 The I/O Network Structure (Daisy Chains) The RS485 Input/Output (I/O) Network connects all input and output communication boards together in a sin- gle open communications loop. This loop, or “daisy chain,” connects the E2 to multiple input and output com- munication boards, and terminates at the last input or out- put board on the network. A diagram of this network arrangement is shown in Figure 6-1. 6.1.5 Network Noise Minimiza- tion Site environments will frequently have numerous sources of high EMI, or “noise,” that must be accounted for when routing RS485 network cable. Although the cable is shielded against noise, the installer must follow best practices for minimizing network noise. In general, installers should follow these guidelines when installing RS485 networks: PAK 32 MultiFlex PAK rack controller MultiFlex PAK CCB 99 CCB case controllers CCBs ESR 31 MultiFlex ESR valve controller MultiFlex ESR CUB- II 32 Single condensing unit controller (one compressor and up to 4 condenser fans) MultiFlex CUB II NOTE: The MultiFlex-plus board replaces the old-style MultiFlex boards and is currently being shipped.

The RS485 Network and Hardware Setup • 6-3 • Avoid running cable next to noise-generating devices, such as motor starters, contactors, invert- ers, fluorescent light ballasts, arc welders, etc. If possible, keep cable less than 1 foot away from noise-generating devices (ideally, at least 5 feet). • Do not run RS485 cable in the same conduit as high-voltage wiring, such as 120VAC or 240VAC power wiring. Keep RS485 cable a minimum of 3 inches away from high-voltage wiring (ideally, at least 12 inches). If RS485 must cross paths with high-voltage wiring, cross them perpendicular — running RS485 and high-voltage wire in parallel increases the amount of noise induced on the net- work. • Ensure you are grounding each input device’s 0V power terminal to a separate earth ground, and set- ting the termination and biasing jumpers as instructed in Section 6.1.8, Setting the Terminating and Biasing Jumpers. For more instructions on best practices for minimizing noise, refer to publication 026-1903, E2 Controller Wir- ing Practices, available in the Product Manuals section of the Emerson Climate Technologies Web site: www.emersonclimate.com 6.1.6 Network ID Numbers (Board Numbers) Each device on an RS485 segment has either a network dip switch or rotary dials that must be used to assign the board a unique network ID number. The network ID number makes a board unique from other boards on the network of the same type. This allows E2 to find it and communicate with it easily. Boards of the same type should be numbered in sequence, starting with one and continuing with two, three, and so forth. For example, if a segment contains four 16AI boards and five 8RO boards, you should num- ber the 16AIs one, two, three, and four; and the 8ROs one, two, three, four, and five. The same should be done with multiple 4AO and 8DO boards, and IRLDS leak detection units. For all boards, except 8IO and 8DO boards, the net- work dip switch labeled S1 (or S3 for the 16AI board) is used to set the unique board number of the unit and the baud rate. The 8IO and 8DO uses rotary dials to set the board number of the unit. Numbering the MultiFlex Combination I/O Boards When it comes to network numbering, the MultiFlex Combination Input/Output boards (88, 88AO, 168, 168AO, and 168DO) are special cases. They are actually a combination of three types of Retail Solutions boards: the inputs are configured like a 16AI, the relay outputs are configured like an 8RO, and the analog outputs are config- ured like a 4AO. When a MultiFlex combo board is present on the net- work, it must be addressed like all three board types. Therefore, when numbering these boards, you must set a unique number for both the 16AI, 8RO, and 4AO compo- nents of the board. Addressing the MultiFlex Boards For MultiFlex boards, set positions 1 to 5 on S3 for the 16AI component and positions 1 to 5 on S4 for the 8RO component. Set positions 6 to 8 on S4 for the 4AO or 4DO segment. For MultiFlex board controllers, use positions 1 to 5 on S3 to set the address. Addressing the MultiFlex ESR Boards The MultiFlex ESR uses standard Retail Solutions I/O Network addressing. Set positions 1 to 5 on S1 to set the network ID (address) of the MultiFlex ESR from 1 to 31. 6.1.7 Setting the Baud Rate All I/O boards have dip switches that determine the baud rate at which they communicate. Currently, the baud rate dip switch in network components may be set at either 4800, 9600, 19200, and 38400. Setting of the baud rate is accomplished using dip switches (refer to the board’s installation sheets at the end of this section for specific dip switch settings). Baud Rate for the E2 The baud rate default for E2 is 9600. Baud Rate for the Gateway The Gateway can be set to either 9600 baud or 19.2K baud by dip switch #6. “ON” places the rate at 9600 baud while “OFF” sets it at 19.2K baud. Dip switches 6 and 7 control the baud rate at which the Gateway communicates with the site controller on the RS485RS485 Network. These switches must be set to the same baud rate setting as the E2 or REFLECS (usually 9600 baud). Dip switch 8 controls the baud rate at which the Gate- way communicates with the other devices on the Receiver Bus Network. This baud rate may only be set to either 9600 baud (switch DOWN) or 19200 baud (switch UP). All Gateways and receivers on the Receiver Bus Network must have the same baud rate dip switch setting. It is rec- ommended you use 9600 baud as the Receiver Bus Net- work baud rate. Baud Rate for the 8IO, 8DO, and ARTC There are three I/O devices that do not have baud rates determined by dip switches. They are as follows:

026-1610 Rev 12 25-APR-2011 1. The 8IO - this board automatically detects the baud rate being used by the I/O devices on the network, and adjusts to match their baud rate. 2. The 8DO - this board automatically detects the baud rate being used by the I/O devices on the network, and adjusts to match their baud rate. 3. The ARTC - this board is fixed at 9600 baud. Baud Rate for MultiFlex Boards On all MultiFlex boards, switches 6 and 7 on S3 are used to set the baud rate. To communicate at 9600 baud, set switch #6 to the UP position and #7 to DOWN. For 19200 baud, set switch #6 to the DOWN position and #7 to UP. Baud Rate for the MultiFlex ESR Set the baud rate on the MultiFlex ESR board by set- ting switches 6 and 7 on the network address terminal (labeled S1). To communicate at 9600 baud, set switch #6 to the UP position, and switch #7 to DOWN. For 19200 baud, set switch #6 to the DOWN position and switch #7 to UP. (Currently, 9600 baud is recommended). Recommended Baud Rate The baud rate should be set to 9600 baud in all cases. 6.1.8 Setting the Terminating and Biasing Jumpers The I/O Network connector, for all I/O boards and the E2, has a set of three terminating jumpers. They are the jumpers positioned closest to the I/O Network connector. The E2 has jumpers next to each of the COM ports that can be configured as an I/O network (COM2, COM4, and COM6). The purpose of the jumpers is to provide network ter- mination resistance and network biasing to the two ends, or termination points, of the daisy chain. One device at the beginning and one device on the end must be terminated and biased by placing all three jumpers in the UP position. All other devices on the daisy chain must have all three jumpers set to the DOWN position. Figure 6-2 shows the proper terminating jumper settings for the E2 and for all I/ O boards. 6.1.9 Powering the I/O Boards All models of E2-compatible I/O boards require 24VAC Class 2 input power. Some boards such as the 16AI, 8RO, 4AO, 8DO, MultiFlex ESR, and MultiFlex 16 use a center-tapped power source. All other models, such as the 8IO and MultiFlex Combination I/O boards, may use non-center tapped power sources. Retail Solutions supplies a wide variety of 24VAC transformers with varying sizes and either with or without center taps. Table 6-2 shows the transformer sizes and whether they are center-tapped or non-center-tapped. Table 6-3 lists each board, the board’s rating, and whether or not the board must use center-tapped power. Figure 6-2 - I/O Network Termination Jumper Settings THE TERMINATING JUMPERS MUST BE IN THE UP POSITION IF AT THE BEGINNING OR END OF THE NETWORK. THE TERMINATING JUMPERS MUST BE IN THE DOWN POSITION IF NOT AT THE BEGINNING OR END OF THE NETWORK.

The RS485 Network and Hardware Setup • 6-5 To select a power transformer for a board or a series of boards: 1. Determine what the total VA is for the boards that will be powered by the transformer (see Table 6-3). Example: Two MultiFlex 168AOs (15 VA each), and one 8DO (18 VA) boards are to be powered by one transformer. The total VA is: 2. Use a transformer that has a power rating higher than the total calculated VA (see Table 6-2). Example: For boards totalling 48VA, a 56VA trans- former is sufficient, since 56VA is greater than 48VA. I/O Board Transformers should be located within 10 feet of the board it is powering, preferably within the board enclosure. 6.1.9.1 Wiring Types For powering I/O boards, use only the listed wire types from Table 6-4. Three-conductor non-shielded cables are the recommended wire for connecting between the center tapped transformer and the I/O boards. The third conduc- tor should be connected to earth ground. If boards use a center-tapped transformer, also connect the center tap to the earth grounded third conductor. The wire length from the transformer and the number of boards connected to the same wire determines the type wire gauge used. In most cases, the distance between the I/ O boards and the transformer that supplies power to them is not enough to be concerned with. But it is very impor- tant not exceed this maximum wire length or the boards will malfunction. Use these formulas to determine if the wire gauge you are using fits within specification: Sensors requiring 24VAC can be powered from the same transformer powering the input board as long as the resulting total load of both the input board(s) and the sen- sor(s) connected to the transformer does not exceed the transformer’s VA rating. Consult Section 6.1.9, Powering the I/O Boards, and Section 8.6.1, Powering Echelon Devices for more information. 6.1.10 Board Installation The following pages give step-by-step graphical instructions on all steps necessary to install each I/O Net- work device so that it is powered up and able to communi- cate with E2.

026-1610 Rev 12 25-APR-2011 above may communicate with IMC/Prodigy rooftop units equipped with IMC/Prodigy control boards version M4-1 or higher. E2 controllers version 2.30F01 and above may use any of the RS485 I/O ports (COM2, COM4, or COM6) as a IMC/Prodigy communication port. Version 2.21F01 E2 units may only connect IMC/Prodigys to an RS485 Expansion Card. Connectivity to IMC/Prodigy is a licensed feature and must be purchased from Retail Solu- tions. The IMC/Prodigy interface has its own technical bulle- tin explaining installation, network setup, and E2 configu- ration. Refer to Technical Bulletin 026-4117. 6.3 ECT MODBUS E2 controllers version 2.30F01 or greater may select ECT MODBUS as a network type. The E2 communicates with MODBUS devices including but not limited to Con- trol Link CD, Control Link RSC, and Control Link ACC. The Control Link products have their own documents explaining device configuration, networking, and E2 setup: • 026-4600 - Control Link RSC Installation Instruc- tions • 026-4601 - Control Link CD Installation Instruc- tions • 026-4703 - Control Link ACC Installation Instruc- tions • 026-4602 - Control Link ECT MODBUS Network- ing to E2s (covers MODBUS installation for all Control Link models) 6.3.1 Control Techniques Drive (VSD) Using the MODBUS network type, E2 controllers can communicate with the Control Techniques variable-speed drive (VSD). There are three different VSD models the E2 communicates with: Commander SE, Commander SK, and Unidrive SP drive types. Note that all CT drives are 2 stop bits, with no parity. Since ECT MODBUS specifies 1 stop bit, CT drives will configure the General Services setting for stop bits and always communicate with the drives using 2 stop bits. The E2 calculates the difference and adjusts for the additional stop bit. Configure the COM port the CT drive will connect to by pressing Alt + M to open the serial configuration man- ager. Set the COM port to MODBUS and the baud rate (match the baud rate on the CT drive). For more informa- tion on setting up serial ports, go to Section 5, Serial Con- figuration. The Control Techniques VSD has its own technical bulletin that explains interfacing with E2 (P/N 026-4122). The installation and operation manual explaining the VSD is maintained by Control Techniques. Contact your Con- trol Techniques representative for a copy of this manual. 6.3.2 Copeland ISD Compressors E2 controllers version 2.21F01 and above may com- municate with Copeland ISD compressors using the ECT MODBUS network. E2 controllers version 2.30F01 and above may use any of the RS485 I/O ports (COM2, COM4, or COM6) as a Copeland ISD communication port. Version 2.21F01 E2 units may only connect Cope- land ISD compressors to an RS485 Expansion Card. The installation and operation manual explaining the Copeland ISD interface is maintained by Copeland. Con- tact your Copeland representative for a copy of this man- ual. 6.3.3 XR, XEV, and XEV22D Case Controllers E2 controllers version 2.84 or greater communicate with the XR and XEV controllers. The XR and XEV con- trol compressor regulation, defrost, light, and evaporator fans in refrigeration systems on normal, low, or medium temperatures, control a wide variety of stepper electronic expansion valves and anti-sweat heaters (if present), and measure and regulate the superheat of the refrigerant in the system. If the case controller is configured with a Real Time Clock (RTC), it can be programmed with up to 6 daily defrosts and an energy saving function. Without the RTC, the E2 can coordinate defrost cycles and the energy-saving function. Several parameters of the Emerson controllers (such as inputs, outputs, setpoints, and alarms) can be configured directly in E2 and sent to the appropriate Emerson control- ler, depending on the controller model.

6.3.4 iPro DAC The iPro DAC is a packaged HVAC control board for use either as a stand-alone controller or in zone control applications using a Retail Solutions E2 BX building con- trol system. The iPro DAC is capable of controlling heat and cool stages, fans, humidification and dehumidification devices and economizers using on-board I/O and control algorithms, as well as monitor and interact with other building control systems and peripherals (such as smoke alarms and CO2 sensors). 6.3.5 Energy Meter 6.3.5.1 Overview The Energy Meter provides a solution for measuring energy data with a single device. Inputs include Control Power, CT, and 3-phase voltage. The Energy Meter sup- ports multiple output options, including solid state relay contacts, Modbus (with or without data logging), and pulse. The LCD screen on the faceplate allows instant out- put viewing. The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN50022. The Energy Meter can be mounted with any orientation over the entire ambient temperature range, either on a DIN rail or in a panel. The meter is not sensitive to CT orientation to reduce installation errors. 6.3.5.2 Supported System Types The Energy Meter Series has a number of different possible system wiring configurations. To configure the meter, set the System Type via the User Interface or Mod- bus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Set- ting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to cal- culate the Theoretical Maximum System Power, and deter- mines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line-to- Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40). For more information about this application, see the Energy Meter manual (P/N 026-1726). 6.3.6 Modular Refrigerant Leak Detection Sensor (MRLDS) Modular Refrigerant Leak Detection Sensor (MRLDS) that continuously monitors for low levels of refrigerants most commonly used in commercial refrigeration systems The MRLDS communicates with the E2 controller via MODBUS.

E2 Ethernet Peer Communications • 7-1 7 E2 Ethernet Peer Communications Communication between E2 controller version 2.10 or greater may now be implemented through an Ethernet net- work using TCP/IP protocol. To utilize peer connections over Ethernet, the following tasks must be performed: • Upgrade the E2 controller firmware to version 2.10 or greater. • Install an industry-standard Ethernet switch(es) or hub(s) in an area or areas nearby the E2 controllers. • Install Ethernet straight-through cabling at the site from each E2 to the switch or hub. Installation of RJ-45 connectors may be necessary to achieve this goal. The recommended cabling is CAT 5. 7.1 Ethernet IP Configura- tions If using an open network configuration (see Section 7.4.2, Open Network Layout), contact your IT Network Administrator for all IP configuration information (IP Address, Subnet Mask, Primary and Default Gateway set- tings). 7.2 Hardware Specifica- tions Standard industry-accepted practices for wiring of Eth- ernet networks are expected. E2 controllers use a star topology, identical to PC deployment. This includes a unique “point-to-point” run from a switch or hub to the controller (see Table 7-1 for hub part numbers for order- ing). This is done with Category5 (or better) cable. Maxi- mum distance for a run of 10BaseT is 328 feet (100 meters) (11.5 dB loss max). • The maximum number of controllers allowed on an IP subnet is 20. All E2 controllers that must com- municate with each other must be on the same sub- net. • Recommended Ethernet cabling is CAT 5 (straight- through cable). • 328 feet (100 meters) is the maximum distance allowed between devices before a switch or hub must be added. 7.2.1 Components Equipment Type Specifications Ethernet Five- or Nine-port Switch (may require an additional power supply) * Industrial grade * Operating/storage temp range: -40°F to 185°F * Vibration: IEC68-2-6 * RH: 5 to 95% * UL 508A, CE approved * Supports 10Base-T crossover cable * Supports all IEEE 802.3 proto- col * Supports Auto Crossover MDI/MDI-X * Screw-terminal power connec- tors Ethernet Surge and Lightning Protector (recom- mended) * Industrial grade * Surge capacity: 1 kA / line *Operating temp range: -40°F to 185°F *Max frequency: 155 MHz *Clamp and rated: 10V and 5V 10-Base-T/100- Base-TX Hub Room Temperature (0 to 50 C) P/N 570-0100 10-Base-T/100- Base-TX Hub Extended Temperature (-40 to 65 C) P/N 570-0200 Table 7-1 - Equipment for E2 Ethernet Peer Communications NOTE: An external power supply may be needed.

026-1610 Rev 12 25-APR-2011 7.3 Software Specifica- tions TCP/IP E2 controller versions 2.10 and later communicate between controllers using the TCP/IP protocol. TCP Port 7238 is the default for connections established between the controllers. All peer communications occur over this port. 7.4 Ethernet Network Layouts The two types of network options for E2 controllers using Ethernet communications are: 1. “Closed Network” - E2 devices are not connected to a store’s LAN. (The only devices on the net- work are the E2 controllers themselves.) This network type is used if there is no need to inte- grate the network into the company’s intranet. 2. “Open Network” - E2 devices are connected to the store’s LAN. (Devices on the network include E2s and other Ethernet-TCP/IP devices.) This network type is used if the network will be con- nected to the store’s LAN. The E2 peer Ethernet network facilitates communica- tions between E2 controllers. These include at least the following: • Routing of messages between external entities such as UltraSite, InSite, Site Manager, and non-gateway E2 controllers. • Distribution of global data and other network variables such as system time, controller iden- tification, etc. • Communication between E2 controller applica- tions such as Remote Login and Remote File Services. 7.4.1 Closed Network Layout NOTE: Contact your IT Network Administra- tor for setup parameters for both closed and open networks. NOTE: The gateway E2 is the E2 controller at a remote site to which UltraSite directly con- nects. It is through this E2 that UltraSite com- municates with the other controllers (defined as the “non-gateway” E2s and external entities such as UltraSite, InSite, Site Manager etc.).

Change Network Type to: Ethernet (ETH) and press Enter. The Group Name field is now visi- ble. 5. Once the Ethernet network type is enabled, enter Figure 7-2 - Open Network Layout NOTE: DHCP does not have to be enabled if you have the IP Address, Subnet Mask, and Primary Gateway settings. (Contact your IT Network Administrator for all IP configuration infor- mation.) If you do not have the IP configuration set- tings, and there is a DHCP server on the network, set DHCP Enabled to Yes and it will retrieve the informa- tion from the server and populate those fields. E2 con- trollers must all have the same Ethernet Subnet in order to communicate box-to-box.

8 Echelon Network and Hardware Setup 8.1 Overview Echelon is an optional, two-conductor network that interconnects E2s and other associated devices, such as CC-100 case controllers, TD3 temperature displays, and ESR8 evaporator stepper regulator boards. All Echelon devices are wired together using the daisy-chain method of network structuring. If an Echelon network-enabled E2 is required, it must be specifically ordered from Retail Solutions as an Echelon-enabled E2, and equipped with an Echelon plug-in card. See Section 4.3.1, Echelon Card Plug-In (P/N 537-4860) with mounting screw (P/N 101-4201). 8.2 Wiring Type Retail Solutions specifies one type of cable for Echelon Network wiring. This cable type’s properties are listed in Table 8-1. 8.3 Echelon Network Structuring (Daisy-Chains) Echelon devices are networked together into configu- rations called segments. A segment is a group of up to 64 Echelon devices that are connected together on an unbro- ken series of wires. The recommended way of constructing an Echelon Network is called daisy-chaining. In the daisy-chain net- work configuration, devices are arranged by subnets, which consist of one E2 and all Echelon devices associ- ated with the E2. First, all devices in a subnet are connected in an unbro- ken chain without branches or “star configurations” (see Figure 8-1). Then, if more than one E2 is present on-site, all chains are connected so that the entire network forms a large unbroken chain, called a daisy chain (see Figure 8-2). This allows for all devices in the Eche- lon Network to be hard wired together for trouble free communication.

026-1610 Rev 12 25-APR-2011 8.3.1 Maximum Number of Eche- lon Devices A daisy-chained segment may contain no more than 63 total Echelon devices (also called "nodes"). If there are 64 or more Echelon devices at your site, an Echelon-compati- ble router (P/N 572-4200) will be required. A router placed on the Echelon Network allows you to add another 63-node daisy-chain network. For larger installations, multiple routers can be used to extend the network indefi- nitely. More information about routers and how they are used in a daisy-chain Echelon Network can be found in the Router and Repeater Installation Guide (P/N 026-1605). 8.4 Device Termination In a daisy-chain configuration, both ends of the net- work segment must be terminated. Terminate the E2 by setting jumper JP7 to the UP position, as shown in Figure 8-3. Other devices on the Echelon Network are terminated either by jumpers on the control board or by connecting a 102-ohm “terminator block” at the end of the network seg- ment (see Section 8.4.1, Using a Termination Block (P/N 535-2715) to Terminate a Daisy Chain). Refer to the installation guide references at the end of this section for specific device termination instructions. All other E2s and Echelon devices that aren’t at the end of a daisy-chained network segment must be untermi- nated. If a router or repeater is being used in a network, termi- nation becomes more complicated, because routers and repeaters join multiple daisy-chain segments together. Refer to the Router and Repeater Installation Guide (P/N 026-1605), for specific termination instructions. Figure 8-1 - Echelon Wiring - Subnets Figure 8-2 - Echelon Wiring, pt. 2 E2 E2 E226513125rev RECOMMENDED UNBROKEN CHAIN E2s E226513131rev Figure 8-3 - E2 Termination - Daisy Chain JP7 JP7 E2 Termination

8.4.1 Using a Termination Block (P/N 535-2715) to Terminate a Daisy Chain Some Echelon Network devices, notably TD3s, have no on-board means of terminating. For some other devices, it is inconvenient to use the jumpers supplied for termination (the CC-100/CS-100 case controllers, for example, require the enclosure to be removed to set the jumper). To remedy these problems, Retail Solutions supplies termination blocks that can be wired to the end of an Eche- lon cable segment. This termination block uses the same three-pin connector as all other Echelon devices. Wire the two signal wires to the outside terminals, and connect the shield to the middle terminal (see Figure 8-4). 8.5 Wire Restrictions Maximum Total Segment Length The total amount of wire used to connect all E2s and associated controllers in a single segment (not including devices on the other side of routers) cannot be longer than 4592 feet (1400 meters). If the total length of cable used is longer than 4592 feet, a repeater or router will be required. Routers act as communication gateways that reduce the amount of network traffic. They are used when net- works exceed their 63-node limit. Adding a router allows you to add another daisy-chain segment of 4592 feet with a maximum of 63 more nodes. Repeaters boost signal strength and are only used in instances where a segment of 63 nodes or less uses more than 4592 feet of Echelon cable. Refer to the Router and Repeater Installation Guide (P/N 026-1605), for information about router and repeater placement. 8.6 Installing Echelon Devices The E2 control system has several types of peripheral control boards that communicate using the Echelon Net- work: the 16AIe analog input board, the 8ROe relay out- put board, the CC-100/CS-100 series of case control and case circuit control boards, and the ESR8 board. 8.6.1 Powering Echelon Devices All Echelon devices require 24VAC Class 2 power. Retail Solutions specs several sizes of transformers to accommodate the full range of Retail Solutions’ Echelon- compatible products. Table 8-3 lists each transformer’s part number and rating. To select a power transformer for one or more Echelon devices: 1. Determine what the total VA is for the boards and controllers that will be powered by the transformer (see Table 8-4). Example: Two TD3 boards (4 VA each), and one E2 (40 VA) board are to be powered by one transformer. The total VA is: NOTE: The recommended termination proce- dure for all Echelon devices is the termination block. Figure 8-4 - Placement and Wiring of the Termination Block CAUTION: Do not power Echelon devices with the same 56VA and 80VA transformers used to power the I/O Network. Echelon devices require Class 2 power to operate, which is not supplied by the I/O board transformers. Xformer P/N VA Rating Input Voltage 640-0039 10 VA 110 VAC 640-0041 50 VA 110 VAC 640-0042 50 VA 220 VAC 640-0050 75 VA 110 VAC 640-0045 75 VA 220 VAC Table 8-3 - Class 2 Transformers for Echelon Devices

026-1610 Rev 12 25-APR-2011 2. Use a transformer that has a power rating equal to or higher than the total calculated VA (see Table 8-3). Example: Boards totaling 48VA can be connected to either a 50VA or 75VA transformer. Refer to the installation guides on the next few pages for instructions on how to install these boards on the Eche- lon Network. 8.7 LEDs The Echelon Board LEDs can be used to determine the status of normal operating parameters for the board. 8.8 Open Echelon Device Connectivity Open-Echelon E2s must be ordered pre-configured from Retail Solutions. Open-Echelon licenses must be purchased and enabled on units, and are not transferrable to other units without assistance from Retail Solutions. Call 770-425-2724 for technical assistance or your sales representative.

Input and Output Setup • 9-1 9 Input and Output Setup 9.1 The 16AI, 8IO, and MultiFlex Inputs 9.1.1 Connecting Sensors to Input Boards There are five network boards that may accept inputs: on the I/O Network, the MultiFlex, 16AI, ARTC, and the 8IO Combination Input/Output Board. Wiring an input to these boards requires three steps: 1. Connect the sensor’s signal wires to the two ter- minals of an input point. 2. Set the input type dip switch that corresponds to the point being connected. 3. If necessary, connect the power lead of the sensor to one of the 5V or 12V power terminals. 9.1.1.1 Wiring MultiFlex Boards An input point connector on a MultiFlex, 16AI, and 16AIe board consists of two terminals, as shown in Figure 9-1. One of these terminals, labeled “SIG”, reads the sig- nal from the sensor, while the other, labeled “0v” is where sensor’s ground and/or cable shield wire is connected. 16AI Boards On a 16AI, terminals are numbered 1-32, starting with the first terminal of point 1 and ending with the last termi- nal of point 16. The even-numbered terminals of a 16AI are always where the signal voltages are connected. The sensor grounds and cable shields are connected to the odd- numbered terminals. 8IO and ARTC Boards On an 8IO board, the two terminals of every point are labeled “-” or “+”. The ground wire is always connected to the “-” terminal, and the signal wire is connected to the “+” terminal. On the ARTC board, the input and output points are predefined and are labeled accordingly. 9.1.1.2 Sensor Wiring Types Specific wiring types are required for each type of sen- sor used with E2. All Analog Temperature Sensors and Air Flow Sensors Temperature and air flow sensors are to be wired with shielded, 2 conductor, at least 22 GA wire (Belden # 8761 or equivalent). All Pressure Transducers, Humidity Sensors, and Refrigeration Transducers Pressure and refrigeration transducers and humidity sensors are to be wired with shielded, 3 conductor, at least 22 GA wire (Belden #8771 or equivalent). Dewpoint and Light Level Sensors These sensors are to be wired with shielded, 4 conduc- tor at least 22 GA wire (Belden # 8729 or equivalent). 9.1.1.3 Input Type Dip Switches An input type dip switch must be set for each input point. Input type dip switches are located in the switch banks labeled S1 and S2 on the MultiFlex, 16AI, and switch bank S4 on the 8IO. The input type dip switch tells the input board whether or not the sensor connected to the point requires a DC sup- ply voltage in order to operate. If the sensor requires DC voltage, the dip switch should be set to the DOWN posi- tion. If the sensor does not require power, or if it uses AC power, the dip switch should be set to the UP position. Dip switches for unused points should be set to the UP posi- tion. The dip switch positions for each specific sensor type is shown in Figure 9-2. Figure 9-1 - Input Board Points

026-1610 Rev 12 25-APR-2011 9.1.2 Power Connection If power is needed to operate the sensor, several termi- nals exist on the 16AI, Multiflex boards, 8IO, that may be used to supply DC power (see Figure 9-3 for 16AI and MultiFlex power connections). Input boards may supply 12VDC or 5VDC. To connect to one of the DC power sources, simply connect the sen- sor’s power wire to one of the terminals. The maximum current that may be drawn from the +12VDC terminal is 100 milliamps. The maximum cur- rent that can be drawn from all three +5VDC terminals COMBINED is 50 milliamps. Specific wiring instructions for each type of sensor are given in Table 9-1 on page 9-3.

026-1610 Rev 12 25-APR-2011 9.1.3 Input Setup in E2 At this point in the setup process, you should have all sensors, transducers, and other input devices wired to points on MultiFlexes, 16AIs, and all output devices con- nected to 8ROs, 8DOs, or 4AOs outputs. Once the physi- cal wiring is complete, you will need to tell E2 the types of sensors or devices that are connected to each I/O point. This is achieved in the Input and Output Definitions screens. 9.1.3.1 Configuring a Point from the Input Definitions/Status Screen To configure a point, go to the Input Definitions/Status screen: 1. Press  to open the Main Menu 2. Press  (System Configuration) 3. Press  (Input Definitions) The Input Status screen opens: Use the up and down arrow keys to move the cursor to the point you wish to set up, and press  (SETUP). A pop-up menu such as the one shown in Figure 9-5 will prompt you to specify the point as analog or digital.

Input and Output Setup • 9-7 ital, or press  to cancel setup. Depending upon what type of input you selected, the Analog Input or the Digital Input screen will appear. The analog screen is described in Section 9.1.3.3, while the digital screen is described in Section 9.1.3.4. 9.1.3.2 Using the Input Definitions/Status Screen In order for the E2 to properly read an input value from a sensor or transducer hooked to an I/O board, you must first tell the E2 what kinds of devices are hooked into each input board point. This is achieved by using the Input Def- initions/Status screen.  (SETUP),  (DEL/MOD),  (OFFSET),  (LOOK UP), and  (CAN- CEL) are the function keys along the bottom of the screen available for the Input Definitions/Status screen. Each record in this screen contains the following infor- mation about a point: 1. Board Type (read-only) The Board Type column will read 16AI regardless of whether the input board is a 16AI, MultiFlex 16, 8IO, or MultiFlex Combination I/O board. 2. Brd (read-only) The point’s board number will appear in its point record under the Brd column. All input boards on a con- troller will be displayed. 3. Pt (read-only) The point number of each point appears in its record under the Pt column. 4. Type (read-only) The Type field shows the output’s data type. Possible Types are: A (Analog) or D (Digital). If the point has not been identified, a “-” will appear in the field instead. 5. Application Select which application you wish to set up inputs to. Pressing  (LOOK UP) when on a defined point will open the Application Selection menu--a list of application types currently existing in the box.  (CANCEL) will cancel this menu. 6. Association If a point has already been defined and is currently being used by an application, the name of the input to which the point is connected will be displayed in the Asso- ciation field. Association is the application’s user-defined property that is associated with the point. Multiple applications attached to single input will all be displayed in the Associ- ation field. Pressing  (LOOK UP) on a set applica- tion will bring up a list of property selections.  (CANCEL) will cancel this menu. 7. Value (read-only) Value shows the sensor value in the units you select for the input type. 9.1.3.3 Setting Up Analog Inputs Open the Analog Input screen by selecting an Analog (A) input from the Input Status screen Figure 9-4 and pressing  (SETUP). The Analog Input screen Figure 9-4 is where sensor types, units, and default values are specified for analog input points. Figure 9-5 - Data Type Pop-Up Menu NOTE: When setting up 88s and 8AOs, re- member that there are only eight usable input points, even though the 16AI that represents the 88s and 8AOs in the summary screen has sixteen points. Only inputs one through eight may be defined; all other points will be ignored. NOTE: When changes are made to the Appli- cation or Association fields, data will not be saved until attempting to arrow off of that par- ticular board and point or attempting to leave the screen. If Type has changed, data will be saved and then the controller will take you to the Setup In screen.

026-1610 Rev 12 25-APR-2011 Point Name The Point Name is simply a name for the point that may be used as a reference. Assigning a descriptive name to a point makes setting up inputs for applications much easier. For example, if you have an inside temperature sensor located in Zone 1 of your building, you may name it “ZONE 1 TEMP”. Then, when programming your HVAC applications, you may easily define Zone 1’s temper- ature sensor input by tying it to ZONE 1 TEMP. This keeps you from having to keep track of which sen- sors are tied to which point numbers. You are required to enter a point name in the Point Name field. The default name is “:{BOARD NAME}:{BOARD NUMBER}:{POINT NUM- BER}.” Board/Point # The Board/Point number will auto- matically be defined if you are configuring the point from the Input Status screen. Sensor Type The analog input may come from a number of different sensor types. Select Eng.

Input and Output Setup • 9-9 sensor value are entered in the Select Eng. Units field. This value is set automatically to an appropri- ate default unit whenever the Sensor Type is changed. To select a different engineering unit, press  or  to scroll through the options or select the unit from the  (LOOK-UP). Units Per Pulse The Units Per Pulse field appears only when “Pulse Accum” is entered in the Sensor Type field. The E2 is capable of generating an analog KW value by counting the number of pulses from the pulse accumulation outputs of a KW transducer. Each pulse from the transducer signifies that a fixed num- ber of KW has been used. The number of KWs per pulse varies depending upon the type of transducer being used. Consult the trans- ducer’s documentation for the exact number of KWs per pulse and enter it in this field. Default on Open The value placed here will deter- mine the value the unit reports if there is an “open” condition detected in the sensor input connection. An “open” condition could be the result of a broken wire to the sensor or a sensor failure. Default on Short The numeric entry in this param- eter is the default value the analog input would report if a “short” is detected on the sensor input connec- tion. A “short” could be the result of a damaged wire or a sensor failure. Default Other The value placed in Default Other is the value reported if the input is not updated after a certain amount of time. If there is a failure that will not allow the input board to report the value of the sensor, the value placed in this parameter will be reported. Sensor Offset If a sensor needs a numeric value added or subtracted to the calculated value, enter the number here. The value can be positive or negative. Sensors sometimes have to have offsets. The offset that you enter in this field is in the units you selected in the Eng Units field, NOT in millivolts. Output This field displays the link between the input and the application(s) they feed into. You do not need to enter anything in this field. You will be able to link applications to this point during the application setup process. 9.1.3.4 Setting Up Digital Inputs Open the Digital Input screen by selecting a Digital (D) input from the Input Status screen Figure 9-4 and pressing  (SETUP). Set up digital inputs in order to assign digital input points, point names, engineering units, and other impor- tant parameters. Point Name The Point Name is simply a name for the point that may be used as a reference. Assigning a descriptive name to a point makes set- ting up inputs for applications much easier. For example, if you are setting up a push-button switch to reset compressor 1 after an oil failure shut down, you may choose to name it “OIL RESET 1”. Then, when programming your Pressure Control applica- tion, you may easily define compressor 1’s reset input by tying it to OIL RESET 1. This keeps you from having to keep track of which contacts are tied to which point numbers. You are required to enter a point name in the Point Name field. The default name is “:{BOARD NAME}:{BOARD NUMBER}:{POINT NUM- BER}.” Board/Point Number The Board/Point Number will automatically be defined if you are configuring the point from the Input Summary Screen. Select Eng. Units The Select Eng. Units field is where you may select how the ON and OFF states of this point are displayed and represented in E2’s setup fields and status screens. By default, digital inputs have ON-OFF engineering units, meaning when the input is ON or OFF, the input will be represented as “ON” or “OFF” in the system software. Since the controller looks at only the actual state of the point when it uses the input for control purposes, it is not necessary to define engineering units for dig- ital inputs. However, selecting units that are appro- priate to the input’s function (such as BYP or Figure 9-7 - Digital Input Screen

026-1610 Rev 12 25-APR-2011 NO_BYP for inputs that initiate bypasses) will make the input’s state easier to read and understand. To choose an engineering unit, press  (LOOK UP) to select. Push Button Mode? Digital inputs may be set up as “push button” inputs by changing this field to “YES”. Push Button Mode is a method of interpreting a digi- tal state that is used strictly for push buttons. When used, a button press lasting longer than one second will change the state of the input. In other words, if the input is OFF, a button press will change it to ON, and another button press will change it back to OFF, etc. Output This field displays the link between the input and its application(s). You do not need to enter any- thing in this field. You will be able to link applica- tions to this point during the application setup process. 9.2 The 8RO, 8ROe, 8IO, and MultiFlex Outputs The 8RO, 8ROe, 8IO, and MultiFlex have relay out- puts that close when called to be ON and open when called to be OFF. When an output point is closed (ON), the LED directly above the output terminal glows red. These boards use Form C contacts that determine if the connection will be open or closed during power failure. A fail-safe dip switch is used to determine connection status during net- work failure. 9.2.1 Wiring Form C Contacts Figure 9-8 shows how to wire the three-terminal Form C contact. One wire of the two-wire connection should always be connected to the middle terminal. The second wire must be connected to the N.C. terminal (if you want the relay to be closed (ON) during power failure) or the N.O. terminal (if you want the relay to be (OFF) during power failure). 9.2.2 MultiFlex Relay Outputs The MultiFlex boards that have relay outputs (all mod- els except the MultiFlex 16) each have eight relays that energize and de-energize to control output loads. When setting up an output on one of these relays, you must make two important decisions: 1. Do you want an ON command from your control- ler to mean “energize the relay” or “de-energize the relay,” and 2. When the relay is de-energized, as is the case when the 8RO or 8IO goes off-line or loses power, do you want the contacts to be OPEN or CLOSED? Decision #1 is made by setting the fail-safe switch. This is a bank of eight switches labeled S2 on the 8RO, 8ROe, and 8RO-FC, S3 on the 8IO, and S1 on the Multi- Flex plug-in output board. Each switch corresponds to an output on the board (switch #1 = output #1, etc.). Decision #2 is made either by setting a fail-safe jumper (for old-style 8ROs) or by wiring the load to either the N.O. or N.C. terminals on the Form C contact (all other output boards). Table 9-3 shows how the fail-safe switch, jumpers, and/or Form C contacts should be configured based on how you want the output to perform during both normal operation and during network/power loss. 9.2.3 Setting the Fail-Safe Dip Switch The fail-safe dip switch determines the sate of the relay when communication is lost between the board and E2.
