Page 6 of 90 1 INTRODUCTION This document details the installation and operation requirements of the DSE335 module version 4.2 and later, part of the DSEATS® range of products. A separate document covers the DSE335 modules with firmware version prior to version 4.2. The manual forms part of the product and must be kept for the entire life of the product. If the product is passed or supplied to another party, ensure that this document is passed to them for reference purposes. This is not a controlled document. Updates are not automatically informed. Any future updates of this document are included on the DSE website at www.deepseaplc.com The module is designed to provide differing levels of functionality across a common platform. This allows the OEM greater flexibility in the choice of controller to use for a specific application. The module has been designed to allow the operator to control the transfer of the load from Source 1 (S1) to Source 2 (S2), typically the mains supply and a standby generator either manually (via fascia mounted push-buttons) or automatically upon S1 failure. Additionally if configured too, the module automatically starts and stops the generator set (S2) depending upon the status of S1. The user also has the facility to view the system operating parameters via the LCD display to monitor the supplies and indicating the operational status and fault conditions of the module. The powerful ARM microprocessor contained within the module allows for incorporation of a range of complex features: • Text based LCD display (supporting multiple languages) • True RMS Voltage, Current and Power monitoring • Communications capability (RS485 or RS232) • Multiple AC supply monitoring • Fully configurable inputs for use as alarms or a range of different functions. Using a PC and the DSE Configuration Suite software allows alteration of selected operational sequences, timers, alarms and operational sequences. Additionally, the module’s integral front panel configuration editor allows adjustment of this information. A robust plastic case designed for front panel mounting houses the module. Connections are via locking plug and sockets. Access to critical operational sequences and timers for use by qualified engineers, can be protected by a security code. Module access can also be protected by PIN code. Selected parameters can be changed from the module’s front panel. The module is housed in a robust plastic case suitable for panel mounting. Connections to the module are via locking plug and sockets.

057-233 ISSUE: 1 2.6.1 V A RATING OF THE CTS NOTE: Details for 4 mm² cables are shown for reference only. The connectors on the DSE modules are only suitable for cables up to 2.5 mm². The V A burden of the module on the CTs is 0.5 V A. However depending upon the type and length of cabling between the CTs and the module, CTs with a greater V A rating than the module are required. The distance between the CTs and the measuring module must be calculated and cross-referenced against the chart opposite to find the V A burden of the cable itself. If the CTs are fitted within the alternator top box, the star point (common) of the CTs must be connected to system ground (earth) as close as possible to the CTs. This minimises the length of cable used to connect the CTs to the DSE module. Example. If 1.5 mm² cable is used and the distance from the CT to the measuring module is 20 m, then the burden of the cable alone is approximately 15 V A. As the burden of the DSE controller is 0.5 V A, then a CT with a rating of at least 15 + 0.5 V = 15.5 V A must be used. If 2.5 mm² cables are used over the same distance of 20 m, then the burden of the cable on the CT is approximately 7 V A. CT’s required in this instance is at least 7.5 V A (7 + 0.5).

Page 12 of 90 2.6.2 CT POLARITY NOTE: Take care to ensure correct polarity of the CT primary as shown above. If in doubt, check with the CT supplier. Take care to ensure the correct polarity of the CTs. Incorrect CT orientation leads to negative kW readings when the set is supplying power. Take note that paper stick-on labels on CTs that show the orientation are often incorrectly placed on the CT (!). It is more reliable to use the labelling in the case moulding as an indicator to orientation (if available). To test orientation, run the generator in island mode (not in parallel with any other supply) and load the generator to around 10% of the set rating. Ensure the DSE module shows positive kW for all three individual phase readings. TO GENERATOR TO LIGHTS POLARITY OF CT PRIMARY 2.6.3 CT PHASING Take particular care that the CTs are connected to the correct phases. For instance, ensure that the CT on phase 1 is connected to the terminal on the DSE module intended for connection to the CT for phase 1. Additionally ensure that the voltage sensing for phase 1 is actually connected to generator phase 1. Incorrect connection of the phases as described above results in incorrect power factor (PF) measurements, which in turn results in incorrect kW measurements. One way to check for this is to make use of a single-phase load. Place the load on each phase in turn, run the generator and ensure the kW value appears in the correct phase. For instance if the load is connected to phase 3, ensure the kW figure appears in phase 3 display and not in the display for phase 1 or 2. 2.6.4 CT CLASS Ensure the correct CT type is chosen. For instance if the DSE module is providing overcurrent protection, ensure the CT is capable of measuring the overload level required to be protected against, and at the accuracy level required. For instance, this may mean fitting a protection class CT (P10 type) to maintain high accuracy while the CT is measuring overload currents. Conversely, if the DSE module is using the CT for instrumentation only (current protection is disabled or not fitted to the controller) then measurement class CTs can be used. Again, bear in mind the accuracy required. The DSE module is accurate to better than 1% of the full-scale current reading. To maintain this accuracy fit Class 0.5 or Class 1 CTs. Check with the CT manufacturer for further advice on selecting the CTs. Labelled as p1, k or K Labelled as p2, l or L

057-233 ISSUE: 1 2.9.1 COMMUNICATION PORT USAGE 2.9.1.1 USB CONNECTION NOTE: The DC supply must be connected to the module for configuration by PC. NOTE: For further details of module configuration, refer to DSE Publication: 057-237 DSE335 Configuration Suite PC Software Manual. The USB port is provided to give a simple means of connection between a PC and the controller. Using the DSE Configuration Suite Software, the operator is then able to control the module, starting or stopping the generator, selecting operating modes, etc. Additionally, the various operating parameters (such as output volts, oil pressure, etc.) of the remote generator are available to be viewed or changed. To connect a module to a PC by USB, the following items are required: • DSE335 Controller • DSE Configuration Suite PC Software (Supplied on configuration suite software CD or available from www.deepseaplc.com). • USB cable Type A to Type B. (This is the same cable as often used between a PC and a USB printer) DSE stock this cable: PC Configuration interface lead (USB type A – type B) DSE Part No 016-125

Page 16 of 90 2.9.1.2 RS232 The RS232 port on the controller supports the Modbus RTU protocol. The Gencomm register table for the controller is available upon request from the DSE Technical Support Department. RS232 is for short distance communication (max 15m) and is typically used to connect the controller to a telephone or GSM modem for more remote communications. Many PCs are not fitted with an internal RS232 serial port. DSE DOES NOT recommend the use of USB to RS232 convertors but can recommend PC add-ons to provide the computer with an RS232 port. 2.9.1.3 RECOMMENDED PC RS232 SERIAL PORT ADD-ONS Remember to check these parts are suitable for your PC.

057-233 ISSUE: 1 2.9.1.4 RECOMMENDED EXTERNAL MODEMS NOTE: For GSM modems a SIM card is required, supplied by your GSM network provider • Multitech Global Modem – MultiModem ZBA (PSTN) DSE Part Number 020-252 (Contact DSE Sales for details of localisation kits for these modems) • Sierra Fastrak Xtend GSM modem kit (PSU, Antenna and modem)* DSE Part number 0830-001-01 • For SMS only, a ‘normal’ voice SIM card is required. This enables the controller to send SMS messages to designated mobile phones upon status and alarm conditions. • For a data connection to a PC running the DSE Configuration Suite software, a ‘special’ CSD (Circuit Switched Data) SIM card is required in order for the modem to answer an incoming data call. Many ‘pay as you go’ services do not provide a CSD (Circuit Switched Data) SIM card.

Page 18 of 90 2.9.1.5 RS485 NOTE: For a single module to PC connection and distances up to 6m (8yds) the USB connection method is more suitable and provides for a lower cost alternative to RS485 (which is more suited to longer distance connections). The RS485 port on the series controller supports the Modbus RTU protocol. The DSE Gencomm register table for the controller is available upon request from the DSE Technical Support Department. RS485 is used for point-to-point cable connection of more than one device (maximum 32 devices) and allows for connection to PCs, PLCs and Building Management Systems (to name just a few devices). One advantage of the RS485 interface is the large distance specification (1.2km when using Belden 9841 (or equivalent) cable. This allows for a large distance between the module and a PC running the DSE Configuration Suite software. The operator is then able to control the module, selecting operating modes, etc. The various operating parameters (such as output volts, currents, etc.) of the remote ATS can be viewed or changed. 2.9.1.6 RECOMMENDED PC RS485 SERIAL PORT ADD-ONS Remember to check these parts are suitable for your PC.

057-233 ISSUE: 1 2.9.2 DSENET® FOR EXPANSION MODULES NOTE: As a termination resistor is internally fitted to the host controller, the host controller must be the ‘first’ unit on the DSENet®. A termination resistor MUST be fitted to the ‘last’ unit on the DSENet®. For connection details, you are referred to the section entitled ‘typical wiring diagram’ elsewhere in this document. DSENet® is the interconnection cable between the host controller and the expansion module(s) and must not be connect to any device other than DSE equipment designed for connection to the DSENet® Description Specification Cable type Two core screened twisted pair Cable characteristic impedance 120Ω Recommended cable Belden 9841 Belden 9271 Maximum cable length 1200m (¾ mile) when using Belden 9841 or direct equivalent. 600m (666 yds) when using Belden 9271 or direct equivalent. DSENet® topology “Daisy Chain” Bus with no stubs (spurs) DSENet® termination 120Ω. Fitted internally to host controller. Must be fitted externally to the ‘last’ expansion module by the customer. Maximum expansion modules Total 6 devices made up of DSE2130 (up to 2), DSE2157 (up to 2), DSE2548 (up to 2) This gives the possibility of : Maximum 16 additional inputs (DSE2130) Maximum 20 additional relay outputs (DSE2157) Maximum 20 additional LED indicators (DSE2548) 2.10 ADDING AN EXTERNAL SOUNDER TO THE APPLICATION When an external alarm or indicator is required, this can be achieved by using the DSE Configuration Suite PC software to configure an auxiliary output for “Audible Alarm”, and by configuring an auxiliary input for “Alarm Mute” (if required). The audible alarm output activates and de-activates at the same time as the module’s internal sounder. The Alarm mute input and internal alarm mute button activate ‘in parallel’ with each other. Either signal mutes both the internal sounder and audible alarm output. Example of configuration to achieve external sounder with external alarm mute button:

Page 45 of 90 057-233 ISSUE: 1 4.1 CONTROL PUSH-BUTTONS Icon Description Stop / Reset This button places the module into its Stop / Reset mode. This clears any alarm conditions for which the triggering criteria have been removed. If S2 is on load and the module is placed into Stop mode, the module automatically instructs the changeover device to unload the S2 source (Close S2 Output becomes inactive (if used)). If S2 is configured for a generator, the start signal given to the generator controller is also removed. If a Remote Start signal is present while operating in this mode, the remote start does not occur. Manual This button places the module into its Manual mode to allow manual control of the ATS functions. This starts S2 when configured as a generator, and runs it off load. For further details, please see the more detailed description of ‘Manual operation’ elsewhere in this document. Auto This button places the module into its Auto mode. This mode allows the module to control the function of S1 and S2 automatically. The module monitors the remote start input and S1 supply status and once a start request is made, a start request is given to S2 if configured to a generator and once available, placed on load. Upon removal of the starting signal, the module automatically transfers the load from S2 and remove the start signal to the generator observing the return delay timer and cooling timer as necessary. The module then awaits for the next start event. For further details, please see the more detailed description of ‘Auto operation’ elsewhere in this manual. Mode This button allows the user to cycle through different operating Mode and press the Tick to accept the mode change. The modes available are: Test On Load: This mode allows the module to start and load S2 for test purposes. Test Off Load: This mode allows the module to start S2 and leave off load for test purposes. Prohibit Return: This mode is used to prevent the module from returning load the S1 until instructed. For further details, please see the more detailed description of ‘Mode operation’ elsewhere in this manual.

For more information please see the section entitled ‘Protections’ else where in this manual. 4.2.7 EVENT LOG The module maintains a log of past alarms and/or selected status changes. At the time of writing, the modules log is capable of storing the last 250 log entries. Under default factory settings, the event log only includes electrical trip alarms (The event log does not contain Warning alarms); however, this is configurable by the system designer using the DSE Configuration Suite software. Once the log is full, any subsequent shutdown alarms overwrites the oldest entry in the log. Hence, the log always contains the most recent alarms. The module logs the alarm, along with the date and time of the event (or engine running hours if configured to do so). If the module is configured and connected to send SMS text To view the event log, repeatedly press the next page button until the LCD screen displays the Event log : 1 Event log S1 Failure Warning 23 Mar 2014, 08:25:46 Press down to view the next most recent shutdown alarm: Continuing to press down cycles through the past alarms after which the display shows the most recent alarm and the cycle begins again.

This section is included to give information about the RS232 serial port and external modem (if connected). The items displayed on this page change depending upon configuration of the module. Refer to the system supplier for further details. Module Connected To an RS232 Telephone Modem NOTE: Not all alarms generate a dial out command; this is dependant upon module configuration of the event log. Any event configured to be recorded in the event log causes the modem to dial out to a PC. When the module is powered up, it sends ‘initialisation strings’ to the connected modem. It is important therefore that the modem is already powered, or is powered up at the same time as the module. At regular intervals after power up, the modem is reset, and reinitialised, to ensure the modem does not ‘hang up’. If the module does not correctly communicate with the modem, “Modem initialising’ appears on the Serial Port instrument screen as shown overleaf. If the module is set for “incoming calls” or for “incoming and outgoing calls”, once the modem is dialled, it answers after two rings (using the factory setting ‘initialisation strings). Once the call is established, all data is passed between the dialling PC and the module. If the module is set for “outgoing calls” or for “incoming and outgoing calls”, then the module dials out whenever an alarm is generated. Press the Scroll Down button view the modem status.... Indicates that the RS232 port is configured for modem use. It displays ‘RS232’ if no modem is configured.

057-233 ISSUE: 1 Page 52 of 90 Module Connected To an RS232 GSM Modem NOTE: Not all alarms generate a dial out command; this is dependant upon module configuration of the event log. Any event configured to be recorded in the event log causes the modem to dial out to a PC. NOTE: In the case of GSM modems, it is important that a DATA ENABLED SIM is used. This is often a different number than the ‘voice number’ and is often called Circuit Switched Data (CSD) by the SIM provider. When the module is powered up, it sends ‘initialisation strings’ to the connected modem. It is important therefore that the modem is already powered, or is powered up at the same time as the module. At regular intervals after power up, the modem is reset, and reinitialised, to ensure the modem does not ‘hang up’. If the module does not correctly communicate with the modem, “Modem initialising’ appears on the Serial Port instrument screen as shown overleaf. If the module is set for “incoming calls” or for “incoming and outgoing calls”, once the modem is dialled, it answers after two rings (using the factory setting ‘initialisation strings). Once the call is established, all data is passed between the dialling PC and the module. If the module is set for “outgoing calls” or for “incoming and outgoing calls”, then the module dials out whenever an alarm is generated. Many GSM modems are fitted with a status LED to show operator cell status and ringing indicator. These are a useful troubleshooting tool. In the case of GSM connection problems, try calling the DATA number of the SIMCARD with an ordinary telephone. After two rings, the modem answers the call and then starts ‘squealing’. If this does not happen, check all modem connections and double check with the SIM provider that it is a DATA SIM and can operate as a data modem. DATA is NOT the same as FAX or GPRS and is often called Circuit Switched Data (CSD) by the SIM provider. Press the Scroll Down button view the modem GSM status.... If the GSM modem is not purchased from DSE, ensure that it has been correctly set to operate at 9600 baud. Currently connected GSM operator and signal strength.

Page 53 of 90 057-233 ISSUE: 1 Modem Initialisation Sequence 1) The modem attempts to communicate to the module 2) If the Modem and module communicate successfully: 3) In case of communication failure between the modem and module, the modem is automatically reset and initialisation is attempted once more: In the case of a module that is unable to communicate with the modem, the display continuously cycles between ‘Modem Reset’ and ‘Modem Initialising’ as the module resets the modem and attempts to communicate with it again, this continues until correct communication is established with the modem. In this instance, check connections and verify the modem operation. Module Modem Diagnostics Modem diagnostic screens are included; press the Scroll Down button when viewing the RS232 Serial Port instruments to cycle to the available screens. If modem communication problems are experiencied, this information aids troubleshooting.

057-233 ISSUE: 1 Page 54 of 90 Module RS232 Port Configured For Connection to A Modbus Master The modules operate as a modbus RTU slave device. In a modbus system, there is only one Master, typically a PLC, HMI system or PC SCADA system. This master requests for information from the modbus slave (The module) and may (in control systems) also send request to change operating modes etc. Unless the Master makes a request, the slave is ‘quiet’ on the data link. The factory settings are for the module to communicate at 19200 baud, modbus slave address 10. To use the RS232 port, ensure that ‘port usage’ is correctly set using the DSE Configuration Suite Software. ‘Master inactivity timeout’ must be set to at least twice the value of the system scan time. For example if a modbus master PLC requests data from the module once per second, the timeout must be set to at least 2 seconds The DSE MODBUS document containing register mappings inside the DSE module is available upon request from [email protected]. Email the request along with the serial number of the DSE module to ensure the correct information is sent.

Page 59 of 90 057-233 ISSUE: 1 4.5 OPERATION NOTE: The following descriptions detail the sequences followed by a module containing the standard ‘factory configuration’. Always refer to the configuration source for the exact sequences and timers observed by any particular module in the field. 4.6 QUICKSTART GUIDE This section provides a quick start guide to the module’s operation. 4.6.1 STARTING S2 NOTE: This only applies when S2 is configured as a generator supply. First, select manual mode, this gives the start request to the external generator control… …when S2 becomes available, press the S2 Breaker button to transfer the load.

057-233 ISSUE: 1 Page 60 of 90 4.6.2 STOPPING S2 NOTE: This only applies when S2 is configured as a generator supply. Select Stop/Reset mode. S2 breaker is opened and the start request is removed.

Page 61 of 90 057-233 ISSUE: 1 4.7 STOP/RESET NOTE: If a digital input configured to Panel Lock is active, changing module modes is not possible. Viewing the instruments and event logs is NOT affected by panel lock. Stop mode is activated by pressing the button. In Stop mode , the module removes S2 from load (if necessary) and removes the start signal given to the generator controller (if S2 is configured as a generator and it is running). If S2 is configured as a generator and it does not stop after the cooling down time, the Fail To Stop alarm is activated (subject to if the Fail To Stop timer is enabled and its duration). To detect the generator (S2) is at rest the following must occur: • S2 Frequency must be zero • S2 Voltage must be zero Any latched alarms that have been cleared are reset when Stop mode is entered. S2 is not placed on load (or started if configured as a generator) when in Stop mode . If remote start signals are given, the input is ignored until Auto mode is entered.

057-233 ISSUE: 1 Page 62 of 90 4.8 MANUAL MODE NOTE: If a digital input configured to Panel Lock is active, changing module modes is not possible. Viewing the instruments and event logs is NOT affected by panel lock. Manual mode is activated by pressing the button. In Manual mode, the module actives an output to give a start signal to an external generator controller (if S2 is configured as a generator supply), and if required, change the state of the load switching devices. An LED indicator beside the button confirms this action. 4.8.1 STARTING SEQUENCE NOTE: There is no start delay in this mode of operation. As soon as the Manual mode button is pressed, the output to give a start signal to an external generator controller is activated (if S2 is configured as a generator) If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm appears on the display which shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved loading voltage and frequency (if configured as a generator). 4.8.2 S2 AVAILABLE NOTE: The load transfer signal remains inactive until S2 is seen as available. This prevents loading to a supply that has failed or is not yet available. In Manual mode, the load is not transferred to S2 unless a ‘loading request’ is made and the S2 supply is within limits (if configured as a mains supply) or achieve Loading Voltage and Loading Frequency (if configured as a generator). A loading request can come from a number of sources. • Pressing the Close/Open S2 button • S1 supply out of limits • Activation of an auxiliary input that has been configured to remote start on load • Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs. As the load increases and decreases, the module may (depending upon configuration) remove non- essential loads. This is configured as part of the Load Shedding control settings in the DSE Configuration Suite Software. See section entitled Load Shedding elsewhere in this document for further details.

Page 63 of 90 057-233 ISSUE: 1 Once the load has been transferred to S2, it is not automatically transferred back to the S1 supply. To manually transfer the load back to the mains either: • Pressing the Close/Open S1 button • Pressing the Auto button to return to automatic mode. • Pressing the Start Inhibit button to return to start inhibit mode. For further details of breaker control, see the section entitled “controls and indications” elsewhere in this manual. 4.8.3 STOPPING SEQUENCE In manual mode, S2 continues to run until either: • Pressing the Start Inhibit button to return to start inhibit mode. • Pressing the Auto button to return to automatic mode.

057-233 ISSUE: 1 Page 64 of 90 4.9 AUTOMATIC MODE NOTE: If a digital input configured to Panel Lock is active, changing module modes is not possible. Viewing the instruments and event logs is NOT affected by panel lock. Auto mode is activated by pressing the button. In Auto mode, the module operates fully automatically, changing between the two supplies in case of failure without user intervention. An LED indicator beside the button confirms this action. 4.9.1 WAITING IN AUTO MODE If a starting/loading request is made, the starting sequence begins. Starting/loading requests can be from the following sources: • S1 supply out of limits • Activation of an auxiliary input that has been configured to remote start on load or remote start off load. • Activation of the inbuilt exercise scheduler. • Instruction from external remote telemetry devices using the RS232 or RS485 interface 4.9.2 STARTING SEQUENCE To allow for ‘false’ start/load requests such as S1 brownouts, the Start Delay timer begins. There are individual start delay timers for each of the different start/load request types. When all start/load requests are removed during the Start Delay timer, the unit returns to a stand-by state. If a start/load request is still present at the end of the Start Delay timer, an output to give a start signal to an external generator controller is activated (if S2 is configured as a generator). If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm appears on the display which shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved Loading Voltage and Loading Frequency (if configured as a generator). If a start/load request is present but the starting sequence has not begun, an input configured to ‘Auto Start Inhibit’ could be active.

Page 65 of 90 057-233 ISSUE: 1 4.9.3 S2 AVAILABLE In Auto mode, the load is automatically transferred to S2 when it is within limits (if configured as a mains supply) or achieve loading voltage and frequency (if configured as a generator). If a start/load request is present but S2 does not go on load, an input configured to ‘S2 Load Inhibit’ could be active. A loading request can come from a number of sources. • S1 supply out of limits • Activation of an auxiliary input that has been configured to remote start on load • Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs. NOTE: The load transfer signal remains inactive until S2 is seen as available. This prevents loading to a supply that has failed or is not yet available. As the load increases and decreases, the module may (depending upon configuration) remove non- essential loads. This is configured as part of the Load Shedding control settings in the DSE Configuration Suite Software. See section entitled Load Shedding elsewhere in this document for further details. If all start/load requests are removed, the stopping sequence begins. 4.9.4 STOPPING SEQUENCE The Return Delay timer operates to ensure that the start/load request has been permanently removed and isn’t just a short term removal. In case another start request is made during the Return Delay (or cooling down period when S2 is configured as a generator), the set returns on load. If there are no starting requests at the end of the Return Delay timer, the load is transferred back from the S2 to the S1 supply and the Cooling timer is initiated (when S2 is configured as a generator). The Cooling timer allows S2 (when configured as a generator) to run off load and cool sufficiently before the start signal to the external generator control unit is removed. This is particularly important where turbo chargers are fitted to the engine. After the Cooling timer has expired, the start signal given to the external generator controller is removed..

057-233 ISSUE: 1 Page 66 of 90 4.10 MODE SELECTION NOTE: If a digital input configured to Panel Lock is active, changing module modes is not possible.

The Test on Load mode starts S2 (if configured as a generator) and transfers the load to S2. 4.10.1.1 STARTING SEQUENCE As soon as the Mode is selected and confirmed by pressing the Tick button is pressed, the output to give a start signal to an external generator controller is activated (if S2 is configured as a generator) If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm appears on the display which shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved Loading Voltage and Loading Frequency (if configured as a generator). 4.10.1.2 S2 AVAILABLE In Test on Load mode, the load is automatically transferred to S2 when it is within limits (if configured as a mains supply) or had achieved loading voltage and frequency (if configured as a generator). If a start/load request is present but S2 does not go on load, an input configured to ‘S2 Load Inhibit’ could be active. NOTE: The load transfer signal remains inactive until S2 is seen as available. This prevents loading to a supply that has failed or is not yet available. As the load increases and decreases, the module may (depending upon configuration) remove non- essential loads. This is configured as part of the Load Shedding control settings in the DSE Configuration Suite Software. See section entitled Load Shedding elsewhere in this document for further details. 4.10.1.3 STOPPING SEQUENCE In Test on Load mode, S2 continues to run on load until either: • Pressing the Start Inhibit button to return to start inhibit mode. • Pressing the Auto button to return to automatic mode.

An LED indicator beside the button confirms this action. The Test off Load mode only starts S2 (if configured as a generator) and leave it off load. 4.10.2.1 STARTING SEQUENCE As soon as the Mode is selected and confirmed by pressing the Tick button is pressed, the output to give a start signal to an external generator controller is activated (if S2 is configured as a generator) If the generator fails to start during the S2 Fail Delay timer, an alarm appears on the display which shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved Loading Voltage and Loading Frequency (if configured as a generator). 4.10.2.2 S2 AVAILABLE In Test Off Load mode, the load is not transferred to S2 unless a ‘loading request’ is made and the S2 supply is within limits (if configured as a mains supply) or has achieved loading voltage and frequency (if configured as a generator). A loading request can come from a number of sources. • S1 supply out of limits • Activation of an auxiliary input that has been configured to remote start on load • Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs. NOTE: The load transfer signal remains inactive until S2 is seen as available. This prevents loading to a supply that has failed or is not yet available. As the load increases and decreases, the module may (depending upon configuration) remove non- essential loads. This is configured as part of the Load Shedding control settings in the DSE Configuration Suite Software. See section entitled Load Shedding elsewhere in this document for further details. 4.10.2.3 STOPPING SEQUENCE In Test off Load mode, S2 continues to run on load until either: • Pressing the Start Inhibit button to return to Start Inhibit mode. • Pressing the Auto button to return to Automatic mode.

Starting/loading requests can be from the following sources: • S1 supply out of limits • Activation of an auxiliary input that has been configured to Remote Start On Load or Remote Start Off Load. • Activation of the inbuilt exercise scheduler. • Instruction from external remote telemetry devices using the RS232 or RS485 interface 4.10.3.2 STARTING SEQUENCE To allow for ‘false’ start/load requests such as S1 brownouts, the Start Delay timer begins. There are individual Start Delay timers for each of the different start/load request types. When all start/load requests are removed during the Start Delay timer, the unit returns to a stand-by state. If a start/load request is still present at the end of the Start Delay timer, an output to give a start signal to an external generator controller is activated (if S2 is configured as a generator). If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm appears on the display which shows Fail to Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved Loading Voltage and Loading Frequency (if configured as a generator). If a start/load request is present but the starting sequence has not begun, an input configured to ‘Auto Start Inhibit’ could be active.

Page 69 of 90 057-233 ISSUE: 1 4.10.3.3 S2 AVAILABLE In Prohibit Return mode, the load is automatically transferred to S2 when it is within limits (if configured as a mains supply) or has achieved Loading Voltage and Loading Frequency (if configured as a generator). If a start/load request is present but S2 does not go on load, an input configured to ‘S2 Load Inhibit’ could be active. A loading request can come from a number of sources. • S1 supply out of limits • Activation of an auxiliary input that has been configured to Remote Start On Load • Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs. NOTE: The load transfer signal remains inactive until S2 is seen as available. This prevents loading to a supply that has failed or is not yet available. As the load increases and decreases, the module may (depending upon configuration) remove non- essential loads. This is configured as part of the Load Shedding control settings in the DSE Configuration Suite Software. See section entitled Load Shedding elsewhere in this document for further details. If all start/load requests are removed, the Stopping sequence begins. 4.10.3.4 STOPPING SEQUENCE In Return Inhibit mode, S2 continues to run on load even if S1 has return until either: • Pressing the Start Inhibit button to return to start inhibit mode. • Pressing the Auto button to return to automatic mode.

057-233 ISSUE: 1 Page 70 of 90 4.11 SCHEDULER The controller contains an inbuilt exercise run scheduler, capable of automatically starting and stopping the set. Up to 16 scheduled start/stop sequences can be configured in banks of 8 to either repeat on a 7-day or 28-day cycle. Scheduled runs may be on load or off load depending upon module configuration. Example Screen capture from DSE Configuration Suite Software showing the configuration of the Exercise Scheduler. In this example the set starts at 09:00 on the first Monday of each month and run for 5 hours, then start at 13:30 on every Tuesday and run for 30 minutes. 4.11.1 STOP MODE • Scheduled runs do not occur when the module is in Stop mode. 4.11.2 MANUAL MODE • Scheduled runs do not occur when the module is in Manual mode. • Activation of a Scheduled Run ‘On Load’ when the module is operating Off Load in Manual mode has no effect, the set continues to run Off Load 4.11.3 AUTO MODE • Scheduled runs operate ONLY if the module is in Auto mode with no Electrical Trip alarm present. • If the module is in Stop or Manual mode when a scheduled run begins, S2 is not started (if configured as generator). However, if the module is moved into Auto mode during a scheduled run, S2 is called to start. • Depending upon configuration by the system designer, an external input can be used to inhibit a scheduled run. • If S2 is Off Load in Auto mode and a scheduled run configured to ‘Transfer to S2’ begins, S2 is placed On Load for the duration of the Schedule.

Page 71 of 90 057-233 ISSUE: 1 4.12 LOAD SHEDDING CONTROL This feature may be enabled by the system designer to ensure the loading on S2 is kept to a nominal amount. Conversely as the load increases towards the maximum rating of the set, non-essential loads can be shed to prevent overload of S2. 4.12.1 LOAD SHEDDING CONTROL NOTE: Refer to DSE335 Configuration Suite Manual (DSE part 057-237) for further details on configuring, monitoring and control. The Load Shedding Control feature (if enabled) allows for a maximum of five load shedding steps. When S2 is about to take load, the configured number of Load Shedding Control Outputs at Startup energises. This configurable setting allows (for instance) certain loads to be removed from S2 prior to the set’s load switch being closed. This can be used to ensure the initial loading of the set is kept to a minimum, below the Load Acceptance specification of S2. S2 is then placed on load. The Load Shedding Control scheme begins. When the load reaches the Load Shedding Trip level the Trip Delay timer starts. If S2 loading is still high when the timer expires, the first Load shedding Control output energises. When the load has been above the trip level for the duration of the timer the ‘next’ Load shedding Control output energises and so on until all Load Shedding Control outputs are energised. If at any time the load falls back below the Load Shedding Return level, the Return Time starts. If the load remains below the return level when the timer has expired the ‘highest’ Load Shedding Control output that has been energised is de-energised. This process continues until all outputs have been de-energised. When the set enters a stopping sequence for any reason the Load Shedding control’ outputs are de- energised at the same time as the S2 load switch is signalled to open.

Page 72 of 90 5 PROTECTIONS When an alarm is present, the Audible Alarm sounds and the Common alarm LED if configured illuminates. The audible alarm can be silenced by pressing the Alarm Mute The LCD display jumps from the ‘Information page’ to display the Alarm Page 1/2 Alarm S1 Failure Latched Warning The LCD displays multiple alarms E.g. “S1 Failure Warning”, “Fail to Stop Warning” and “Digital Input A Electrical Trip”. These automatically scroll in the order that they occurred. In the event of a warning alarm, the LCD displays the appropriate text. If an electrical trip then occurs, the module again displays the appropriate text. Example:- Alarm 1/2 Fail to Stop Unlatched Warning Alarm 2/2 Digital Input A Unlatched Electrical Trip The nature of alarm, e.g. S1 Failure The type of alarm. E.g. Electrical Trip or warning Number of present alarms. This is alarm 1 of a total of 2 present alarms If the alarm automatically resets (unlatched) or needs to be manually reset (latched).

057-233 ISSUE: 1 5.1 INDICATIONS Indications are non-critical and often status conditions. They do not appear on the LCD of the module as a text message. However, an output or LED indicator can be configured to draw the operator’s attention to the event. Example • Input configured for indication. • The LCD text does not appear on the module display but can be added in the configuration to remind the system designer what the input is used for. • As the input is configured to Indication there is no alarm generated. • LED Indicator to make LED1 illuminate when Digital Input A is active. • The Insert Card Text allows the system designer to print an insert card detailing the LED function. • Sample showing operation of the LED.

Page 74 of 90 5.2 WARNINGS Warnings are non-critical alarm conditions and do not affect the operation of the system, they serve to draw the operators attention to an undesirable condition. Example 1/2 Alarm S1 Failure Latched Warning In the event of an alarm the LCD jumps to the alarms page, and scroll through all active warnings and shutdowns. By default, warning alarms are self-resetting when the fault condition is removed. However some warning alarms are latched and need to be reset manually. Display Reason Auxiliary Inputs If an auxiliary input has been configured as a warning the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. Battery Under Voltage The DC supply has fallen below the low volts setting level for the duration of the low battery volts timer Battery Over Voltage The DC supply has risen above the high volts setting level for the duration of the high battery volts timer Calibration Lost The module has lost its calibration settings and must be sent back to DSE to be re-calibrated. Expansion Inputs If an expansion input has been configured as a warning the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. Fail To Start S2 has not reached the configured limits or loading voltage and frequency before the S2 Fail Delay timer has expired. Fail To Stop The module has detected a condition that indicates that S2 is present when it has been instructed to stop. Loading Voltage Not Reached Indicates that the S2 voltage is not above the configured loading voltage. S2 does not take load when the alarm is present after the safety timer. NOTE: Only applicable when S2 is configured as a generator supply. Loading Frequency Not Reached Indicates that the S2 frequency is not above the configured loading frequency. S2 does not take load when the alarm is present after the safety timer. NOTE: Only applicable when S2 is configured as a generator supply.

057-233 ISSUE: 1 Display Reason PLC Functions If a PLC Function has been configured as a warning the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. S1 Breaker Auxiliary Fail Indicates that the S1 Closed Auxiliary input has not activated along with the Close S1 Output or Open S1 Output, or the input has activated when the output was not energised. S1 Failure Unlatched The module has detected that S1 has failed for either an under/over voltage/frequency condition. The unlatched alarm is automatically cleared upon S1 returning to an available state. S1 Phase Rotation The module has detected a wrong phase sequence for S1. S2 Breaker Auxiliary Fail Indicates that the S2 Closed Auxiliary input has not activated along with the Close S2 Output or Open S2 Output, or the input has activated when the output was not energised. S2 Failure Unlatched The module has detected that S2 has failed for either an under/over voltage/frequency condition. The unlatched alarm is automatically cleared upon S2 returning to an available state. S2 Phase Rotation The module has detected a wrong phase sequence for S2. 5.3 ELECTRICAL TRIPS Electrical trips are latching unload and stop S2 (if configured as a generator) but in a controlled manner. On initiation of the electrical trip condition the module de-energises the ‘Close S2 Output’ to remove the load from S2. Once this has occurred the module starts the Cooling timer and allow the generator to cool down and shut off. The alarm must be accepted and cleared, and the fault removed to reset the module. Example 1/2 Alarm Digital Input A Latched Electrical Trip Electrical trips are latching alarms and unload and stop S2 (if configured as a generator). To clear these alarms the STOP button is pressed Display Reason Auxiliary Inputs If an auxiliary input has been configured as an electrical trip, the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. Expansion Inputs If an expansion input has been configured as an electrical trip, the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. PLC Functions If a PLC Function has been configured as an electrical trip, the appropriate LCD message is displayed and the COMMON ALARM LED illuminates. S1 Breaker Auxiliary Fail Indicates that the S1 Closed Auxiliary input has not activated along with the Close S1 Output or Open S1 Output, or the input has activated when the output was not energised. S1 Phase Rotation The module has detected a wrong phase sequence for S1. S2 Failure Unlatched The module has detected that S2 has failed for either an under/over voltage/frequency condition. The unlatched alarm is automatically cleared upon S2 returning to an available state. S2 Phase Rotation The module has detected a wrong phase sequence for S2.

Page 82 of 90 7 COMMISSIONING Before the system is started, it is recommended that the following checks are made:- • The unit is adequately cooled and all the wiring to the module is of a standard and rating compatible with the system. Check all mechanical parts are fitted correctly and that all electrical connections (including earths) are sound. • The unit DC supply is fused and connected to the battery and that it is of the correct polarity. • To check the start cycle operation, take appropriate measures to prevent S2 from starting (if configured as a generator by disconnecting the start output) and press the Manual mode button. Check to see if the start signal energises. • Set the modules internal clock/calendar to ensure correct operation of the scheduler and event logging functions. For details of this procedure see section entitled Front Panel Configuration – Editing the date and time. • If, despite repeated checking of the connections between the controller and the customer’s system, satisfactory operation cannot be achieved, then the customer is requested to contact the DSE Technical Support Department for further advice.

Page 83 of 90 8 FAULT FINDING 8.1 STARTING Symptom Possible Remedy Unit is inoperative Read/Write configuration does not operate Check the battery and wiring to the unit. Check the DC supply. Check the DC fuse. Unit shuts down Check DC supply voltage is not above 35 Volts or below 9 Volts Check the operating temperature is not above 70 °C. Check the DC fuse. Fail to Start is activated Check wiring of the S2 sensing cables. Check the start output is correctly wired into the generator controller. Continuous starting of S2 when in Auto mode. Check that there is no signal present on the “Remote Start” input. Check configured polarity is correct. Check the S2 supply available and within configured limits S2 fails to start or go on load on receipt of Remote Start signal. Check S2 Fail Delay timer has timed out. Check signal is on “Remote Start” input. Confirm correct configuration of input is configured to be used as “Remote Start”. 8.2 LOADING Symptom Possible Remedy S2 supply present runs but does not take load Ensure S2 is available and within configured limits and a load inhibit signal is not present on the module inputs. Check connections to the switching device. Note that S2 does not take load in manual mode unless there is an active remote start on load signal. 8.3 ALARMS Symptom Possible Remedy Electrical Trip fault operates Check relevant switch and wiring of fault indicated on LCD display. Check configuration of input. Warning fault operates Check relevant switch and wiring of fault indicated on LCD display. Check configuration of input.

Page 84 of 90 8.4 COMMUNICATIONS Symptom Possible Remedy RS485 inoperative Check : • Connection cable – Belden 9841 or equivalent • 120 Ω termination resistors are correctly fitted • Baud rate of controller and of master device are the same • Slave ID of the controller is the same as configured in the master device RS232 connection to PC inoperative Check : • RS232 maximum of 15 m is not exceeded • Direct to PC connection requires a Crossover (NULL modem) RS232 cable • Baud rate of controller and of master device are the same • Slave ID of the controller is the same as configured in the master device RS232 connection to GSM modem inoperative Check : • RS232 maximum of 15 m is not exceeded • Modem Initialisation strings in the DSE configuration is correct for the connected modem type • Modem is configured to 9600 baud • SIM card is CSD (circuit switched data) compatible • SIM card is not PIN locked • SIM card is correctly inserted • Antenna is correctly installed and is not inside an earthed metal cabinet / control panel • A good signal is available in the locality RS232 connection to landline modem inoperative Check : • RS232 maximum of 15 m is not exceeded • Modem Initialisation strings in the DSE configuration is correct for the connected modem type • Modem is configured to 9600 baud 8.5 INSTRUMENTS Symptom Possible Remedy Inaccurate S1 & S2 measurements on controller display Check that the CT primary, CT secondary and VT ratio settings are correct for the application. Check that the CTs are wired correctly with regards to the direction of current flow (p1,p2 and s1,s2) and additionally ensure that CTs are connected to the correct phase (errors occur if CT1 is connected to phase 2). Remember to consider the power factor. Ie (kW = kV A x powerfactor) The controller is true RMS measuring so gives more accurate display when compared with an ‘averaging’ meter such as an analogue panel meter or some lower specified digital multimeters. Accuracy of the controller is better than 1% of full scale. Ie S1 volts full scale is 333 V ph-n so accuracy is ±3.33 V (1% of 333 V).

057-233 ISSUE: 1 8.6 MISCELLANEOUS NOTE: The above fault finding is provided as a guide check-list only. As the module can be configured to provide a wide range of different features, always refer to the source of the module configuration if in doubt. Symptom Possible Remedy Module appears to ‘revert’ to an earlier configuration When editing a configuration using the PC software it is vital that the configuration is first ‘read’ from the controller before editing it. This edited configuration must then be “written” back to the controller for the changes to take effect. When editing a configuration using the fascia editor, be sure to press the Tick button to save the change before moving to another item or exiting the fascia editor
