Before the IPM V2 can be installed, there are a number of things that need to be considered and understood to prevent incorrect or unsafe operation of the relay or the system into which it is installed. Along with relevant competence, and an understanding of the target application, the following points should be considered: 3.1.1 Ensure that the information provided in this user manual is fully understood. It is extremely important that the limitations and functionality of the IPM V2 are understood to prevent incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the nature of the limitations or their implication, consult a competent authority such as a supervisor or Ampcontrol technical representative. 3.1.2 Ensure that the application into which the relay is being installed has been properly defined, designed and approved. Any system intended to mitigate the risk of injury needs to be properly designed and implemented. Such a system must be the result of structured risk analysis with the outcomes used to define the system requirements. These requirements, in turn, will guide the choice of instrumentation, logic solvers and actuators needed to implement the system. Understanding the needs of the system will ensure proper selection of equipment. 3.1.3 Ensure that the relay will properly perform the required functions within the system design. It is important to understand how the IPM V2 is intended to interact with other equipment within a system. For safe and reliable use, it is crucial that neither the relay’s logical operation nor its signalling be compromised by incompatibilities with connected equipment. 3.1.4 Modifications of any form to the IPM V2 relay are prohibited. The IPM V2 as supplied has been designed and manufactured to comply with the requirements of protection standards. If modifications of any form are made to the relay, the equipment may no longer be fit for use. If any modifications or damage to the relay is evident, do not use the equipment and contact Ampcontrol for advice. 3.2 Mandatory Installation Practices The following information must be adhered to when installing the IPM V2. Failure to adhere to this information may give rise to unsafe operation. Using the IPM V2 in a manner that exceeds its electrical, functional or physical specifications, or in a way that is contrary to its operating restrictions, may create risks to personnel and/or equipment resulting in injury or death. x The relay must be powered within the specified voltage range. x The installation of the relay must be carried out by suitably trained and qualified personnel. x Identification labels fixed to the relay must not be damaged, removed or covered before, during or after installation. x The installation is to be in accordance with the relevant installation Standards/Codes of Practice.

Page 10 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 4 IPM V2 RELAY OVERVIEW The Ampcontrol IPM Integrated Protection Relay (Version IPM V10.0) is an intelligent protection relay based on microprocessor technology. The IPM Integrated Relay provides the necessary functions required for protecting electrical outlets supplying underground mining machinery, powered by reeling or trailing cables, in the metalliferous industry. The relay can also be used to provide optimum overload protection of motors used on conveyors, pumps, fans and compressors. All of the protection functions are combined into a compact, plug-in unit, which can be easily changed out to minimise down time in the event of a problem with the relay. The IPM Integrated Protection Relay can provide Machine Data Transfer through the use of a Remote Termination Module (RTM) connected between the pilot and earth at the machine end of the trailing cable. Through the use of the RTM Remote Termination Module the relay parameters are automatically up loaded from a remote machine when a cable is inserted into a power outlet. The RTM also allows for remote control (starting) of the IPM output. A RS485 Modbus communication port is available that can be connected to Motor Starter PLC's or a central monitoring system for continuous monitoring and fault-finding. The IPM Relay provides an isolated 4-20mA analogue output to continuously monitor Average Current, Overload, Earth Leakage and the Insulation level of the relay. An automatic Insulation Test can be initiated once all starting conditions are met. A high voltage DC “Insulation Test” to earth of the cable is carried out. If the result of the Insulation Test is above the preset resistance level, the IPM’s MCR relay energises, which in turn closes the main contactor. A manual “Insulation Test” is provided as a maintenance/fault finding tool (when this test is performed the MCR relay does not close at completion of a healthy test). The Insulation Test allows cable insulation levels to be trended as an aid to preventative maintenance. The Burp Function allows for the progressive inflation of ventilation bags (tubes) by pulsing the motor contactor controlling a ventilation fan, several times at start up. The Snore Function is available for controlling pumps; the Snore function automatically stops the output on detection of low current and restarts the outlet after a fixed or automatically-adjustable time delay. The IPM Integration Protection Relay has 6 digital inputs, which feed into a microprocessor unit. The microprocessor has been programmed to control three output relays. The relays are MCR (Main Contactor Relay), CBR (Circuit Breaker Relay) and ALM (Alarm Relay). All of the tripping logic and outlet control is performed by the microprocessor, so that virtually no external control is required. A four-line 20 character backlit LCD display combining with a keypad provides an easy to operate user interface. The display provides easy access to all available information. A simple procedure allows adjustment of the relay’s settings. 4.1 Protection Functions The IPM Integrated Protection Relay provides protection functions for: x Earth Leakage x Earth Continuity x Overcurrent x Short Circuit x Under Current x Contactor Fail x Under Voltage Protection trips are stored in a non-volatile memory requiring a reset function before power can be restored to the load. This remains the case even if a power down occurs following a trip condition.

Figure 1 gives an overview of the fascia of the relay. Figure 1: IPM Relay Fascia and Display The layout of the display structure is shown on the ‘IPM Display Map’. The display level is changed with the Up/Down arrow keys and the Left/Right arrow keys control the various display screens. The ENT and ESC keys are used to modify settings and provide hyper jump access to the display structure. The Reset key allows a reset following a trip condition. The Test key is used to activate a manual insulation test. Start and Stop keys are provided for closing and opening the main contactor supplying power to a machine. The Status LED is a single bi-coloured LED that can be viewed some distance from the relay. Status indication is as follows: IPM Status LED Colour LED Flash OK (Run) Green 4Hz OK (Stopped) Green 1Hz Alarm Red 4Hz Trip Red 1Hz The IPM status display is one of the most useful features of the relay’s display system and should be viewed as the first step in fault finding. The ‘Relay Status Page’ is the default screen on power up and shows the current status of the IPM Protection Relay. [ Need IPM Start ] Load [Pump # 1 ] I= 0 Amps V= 0 V

Page 15 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 5 EARTH PROTECTION FUNCTIONS 5.1 Earth Leakage 5.1.1 Introduction Protection systems are defined in AS/NZS 2081 for use in fault limited systems. This standard describes the requirements of Earth Leakage protection to initiate a trip of the circuit interrupting device when a selected value of earth fault current is exceeded for a certain amount of time. All protection systems must comply with this standard as stated in AS/NZS 4871, which sets out the general requirements for the design, construction and testing of electrical equipment directly associated with mining and quarrying activities. Part of these requirements includes designing for electrical faults, and the standard outlines the safe touch potential which must be considered in electrical protection design. Acceptable touch potential levels are described using a series of curves as shown in Figure 2. Figure 2: AS/NZS 4871 Safe Touch Potential Levels (Figure C1 from the standard) The IPM V2 relay Earth Leakage protection function has been designed in accordance with AS/NZS 3190 – Approval and Test Specification – Residual current devices (current-operated earth-leakage devices). Given this, it is important to consider the performance of the Earth Leakage protection provided by the IPM V2 and assess how the relay’s performance compares with the requirements of AS/NZS 2081. Testing was completed to assess the ability of the IPM V2 relay to trip within acceptable levels. The results for the Earth Leakage tripping times of the relay are detailed in Appendix 1. These results show the tripping times are well within those specified by the relevant standards. The tripping times reduce for higher fault currents, improving the performance of the relay. Figure 3 summarises the trip times which can be expected when the trip time is set to be ‘Instantaneous’, for increasing fault currents at different trip levels.

Page 16 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 Figure 3: Instantaneous trip times for a selection of device trip level settings 5.1.2 Earth Leakage Protection Function The Earth Leakage protection function uses a 1000:1 core balance toroid to measure the earth fault current. A Residual Current Device (RCD) operating characteristic is provided with adjustable trip sensitivity and time delay. The % leakage current is displayed on the 'Current and Voltage Information’ page (Level 2, Screen 2) as ‘Ie’ shown as a % of the selected trip level. When the leakage reaches 100% a trip occurs. For timing of the trip refer to Appendix 1. As discussed above the higher the fault current measured, the faster the trip response. To reset the relay following an earth leakage trip, operate the reset key/digital input. The trip level is selected via the ‘RCD Trp. Level’ setting (Level 6, Screen 13) and is adjustable between 25mA and 500mA and off. The time delay is selected via the ‘RCD Trp. Time’ setting (Level 6, Screen 14). Settings are Instantaneous and adjustable settings between 50ms and 150ms. 5.2 Insulation Test The IPM Relay can provide an automatic High Voltage ‘Insulation Test’. A manual ‘Insulation Test’ is also provided. An insulation test module, which is a resistive isolation device, is used to interface the power conductors to the IPM Relay. Modules are selected in the Group 1 Settings ‘ITM Module’ (Level 5, Screen 2) for rated line voltages of 415V and 1000V. The IPM Insulation Test Module (ITM) is the preferred isolation module and must be used when the ‘Insulation Test’ function is required. When “None” is selected the IPM Relay does not provide ‘Insulation Test’, or voltage functions. 5.2.1 Automatic Insulation Test If an ITM Module has been selected, in the adjustable Group 1 Settings and a trip level has been set in the adjustable Group 2 settings, then an automatic High Voltage DC ‘Insulation Test’ is initiated by operation of the start button once all starting conditions are met. The HV DC ‘Insulation Test’ commences when the IPM Relay applies voltage to the V Test terminal of the relay for a period of 2 seconds. This applies 30VDC to the ITM Module. A HV DC voltage is generated in the ITM Module, which applies a voltage of 500V for 415V operation and 820V for 1000V systems, between each phase and earth. 0 50 100 150 200 250 300 100 1000 Trip Time (ms) Fault Current (mA) 25mA 50mA 100mA 200mA 500mA

Page 17 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 The IPM Relay measures the voltage on the line and calculates the resistance to earth for all phases. At the end of the test the result is stored in the Event Log as ‘It:X.XMΩ’ If the resistance value is above the preset threshold the MCR Relay picks up allowing the outlet to be energised. Additionally, if the result is equal to or below an Alarm Level (typically 1.5 times the selected trip level) the status message ‘Insulat.Test Alarm’ is displayed on the Status Page (Level 1, Screen 1). Ins. Tst. Level: Selection MΩ Alarm Level MΩ 1.0 1.5 2.0 3.0 5.0 7.5 10 15 20 30 None None If the value is less than the preset trip level a trip occurs and is latched and saved in a non-volatile memory. To reset the relay following an insulation test fail trip, operate the reset button. x L3: Indicates the status of the insulation test. x L4: Displays the insulation resistance as a result of the test and is retained in memory until the next test is carried out. The trip level is set at ‘Ins.Tst.Level’ page (Level 6, Screen 18) and is selectable. If the ‘Insulation Test’ is not selected by setting the ‘ITM Module’ value to “None” then the MCR Relay closes by operation of the start button. 5.2.2 Manual Insulation Test A manual “Insulation Test” is provided as a maintenance/fault finding tool. The manual test can only be carried out when the load is not energised. A manual insulation test is also prevented when operating in snore mode. Before a manual Insulation Test can be performed the following conditions must apply: 1. The Insulation Test page being displayed. This is located on the ‘Insulation Test’ screen (Level 3, Screen 2). 2. Pilot must be healthy (and any previous trips reset). 3. Insulation Test function must not be tripped. 4. Outlet must not be running. 5. Outlet must not be in the process of ‘closing’. 6. Outlet must not be ‘Paused’ When the above conditions are met the key must be pressed and held (for the duration of the test). After 3 seconds the manual insulation test is initiated. The test voltage is applied to the outgoing feeder while ever the above conditions are held (including holding the key). The test results are continuously calculated and displayed. The operator should maintain the test at least long enough for the readings to stabilise, this being a function of the cable length. Once the test is completed (usually by releasing the key) the results are held in memory until another insulation test is commenced either manually or as part of the starting sequence, or IPM control power is lost. If the ‘ITM Module’ has been set to “None” then the manual test will not function. The status of the manual insulation test is shown on the Insulation Test Screen (Level 3, Screen 2). Insulation Test 3 ---- Not Active ---- Last Test : 8.6MΩ

Page 18 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 The three functions shown on the screen are ‘Not Active’, ‘Arming Man.Ins.Test’ and ‘Manual Insulat. Test’. The display will show the last measured value. 5.3 Earth Continuity The Earth Continuity function tests for the continuity of the earthing between the outlet and the machine, via the pilot core in the trailing cable. The pilot core is also used to transfer data when a Remote Termination Module is used to achieve Machine Data Transfer. The IPM relay can be configured to operate in either diode or RTM mode. The mode is selected in ‘EC Pilot Mode’ (Level 5, Screen 1) and determines what terminating device the relay is looking for on the pilot. The Remote Termination Module will only be recognised by an IPM Relay and will not be seen as a diode by other earth continuity devices. The relay measures the resistance of the pilot - earth loop and the leakage between the pilot and earth conductors. The leakage measurement ensures that pilot to earth faults is detected. If the pilot - earth loop resistance exceeds 45Ω a trip occurs which in turn opens the main contactor control circuit. The fault can be configured as latching or non-latching. This allows the user to determine if the fault is manually or automatically reset once the pilot - earth loop resistance is less than 45Ω. The selection is either ‘EC Trip Latch: On’ or ‘Off” (Level 6, Screen 17). To manually reset the relay, operate the reset button. x L3: Shows the earth continuity resistance (R) of the pilot – earth loop and the leakage (L) between the pilot and earth conductors as a % of the trip levels. When either value reaches 100% a trip occurs. The version of the software is also indicated. x L4: Shows the Load Type and Number (from the connected RTM unit). Pilot Trip Time is adjustable to allow for operation in noisy electrical environments. The trip times can be selected at ‘Pilot Trip t’ (Level 6, Screen 15) and can be set to 80, 120, 160, 200, 300, 400 and 500ms. A setting of 120ms should be suitable for most installations. Long time delays (>200ms) should only be used where necessary. Consequence of long trip times should be thoroughly assessed from a safety point of view before using the higher values. The leakage trip setting is fixed at 1850Ω. Earth Continuity 3 R:27% L: 0% V#10 Load [WPump # 1]

The three phase currents are squared to provide the I2R heating input to the motor model. The selected ‘Stopped Cooling Ratio’ determines the cooling output for the model. The state of the thermal model is shown by the ‘Thermal Accumulator’, which can be viewed on the 'Current/Volts Information' level on the display. The thermal accumulator represents the motor temperature. When the accumulator reaches 100%, a Motor Overload Trip occurs. The full load current is selected via the ‘100% Current’ setting (Level 6, Screen 2) and can be set between 0.5125A and 640A in 448 steps. See the Appendix section of this manual for the respective Full Load Current Selection tables for a 100:1 CT or 1000:1 CT. The trip time is selected via the ‘O/L Trp t @ 6x’ setting (Level 6, Screen 6). It is a function of the current and the selected trip time curve. Refer to Appendix 6 for details of the motor overload and short circuit trip times. The fifteen (15) motor overload curves allow trip settings from 3 to 40 seconds at six (6) times FLC and are shown for both cold and hot conditions. The hot curve corresponds to the trip time after the motor has been running at the selected full load current indefinitely. The trip time can be calculated as follows: Where: C = Curve Selected I = Current (FLC = 1) A% = Initial Thermal Accumulator Value For Cold Start A = 0% and on Hot Start, A = 89%. The motor manufacturer's data should always be consulted to select the appropriate settings for the motor being protected. Typically, the capacity of a cold motor is given at six times its rated current. The IPM Relay's trip curves can then be used to select the trip time curve, which best suits the motors overload capacity. The motor overload trip latches once the thermal accumulator reaches 100% and can only be reset once the thermal accumulator falls below a preset value. The preset value is selected via the ‘O/L Rst Level’ setting (Level 6, Screen 8) and can be set to 30%, 40%, 50%, 60%, 70%, 80%, 90%, A-30%, A-40%, A- 50%, A-60%, A-70%, A-80%, A-90%. The “A-“ settings automatically reset a motor overload trip once the thermal accumulator falls below the set value. Otherwise the trip has to be reset manually by pressing the keypad ‘RESET’ button or activating the ‘RESET’ digital input once the thermal accumulator has fallen below the set value. An emergency restart on a hot motor can be achieved by zeroing the thermal accumulator memory. This is done by closing the Lock input and Reset key/digital input simultaneously for 1.5 seconds. » » » ¼ º « « « ¬ ª   u 1238 .1 100 % 1238 .1 ln 53 . 31 2 2 I A I x C Time Trip

Page 20 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 CAUTION! Repeated restart attempts in this condition may damage the motor. The ‘Stopped Cooling Ratio’ modifies the cooling output of the thermal model when the motor is stopped. This can be used to account for reduced cooling capacity of the motor when it is not running (motor run status monitored via MCI digital input). The ratio is selected via the ‘O/L cool mult’ setting (Level 6, Screen 7) and is adjustable from 1.0 to 5.0. A cooling multiplier of 1 means the cooling is independent of whether the motor is running or not – for example, a water-cooled motor. Protection for a fan-cooled motor is based on a setting of 2.5, however, for the best protection consult the motor manufacturer. 6.2 Short Circuit Protection The short circuit function has a definite time characteristic. If the current exceeds the selected level for the pre-set time then a trip occurs. The short circuit function trips the CBR relay (the CBR relay is normally energised, and drops out when tripped). The short circuit trip level is selected via the ‘Short Cct.Trip’ setting (Level 6, Screen 4) and is a multiple of the selected full load current, from 3.0 to 10 times FLC, in steps of 0.5. The trip time is selected via the ‘Short Cct. t’ setting (Level 6, Screen 5) and is adjustable from 20 to 160ms. To reset the relay following a short circuit trip it is necessary operate the reset key/digital input. 6.3 Phase Current Balance The current balance measurement ‘Ib’ is displayed on the ‘Voltage and Current Information’ page, Level 2, Screen 2. If Iave is <100% the difference between the average current and each phase current is calculated. The maximum difference is used as the current balance percentage. If Iave is >= 100% then the current balance is calculated as: 𝐼𝑏𝑎𝑙= MAX ΔI x 100% 𝐼𝑎𝑣𝑒 Where: Iave = Average of the 3 phase currents MAX Δ I = The maximum deviation of a phase current from the average Phase current balance protection is selected via the ‘Cur.Bal.trip’ setting (Level 6, Screen 9). The trip level is selectable at 5%, 10%, 20%, 50% and OFF. The phase current balance protection is inhibited until the average current exceeds both 20% of the selected full load current and the selected balance trip level. If any phase drops below the selected trip setting for a period of 2 seconds then the outlet is stopped. To reset the relay following a current balance trip, operate the reset key/digital input.

Page 21 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 6.4 Residual Current Signal The three phase current signals are summed electronically in the IPM to produce a residual current signal that can be used to detect earth fault currents. If the residual current signal exceeds the trip level for the selected trip time, a trip occurs, tripping the MCR relay. The fault is latched. To reset the relay following a residual current trip, operate the reset key/digital input. x L2: Displays the 3 phase currents as a % of the FLC x L3: Displays the average current and the % residual current as ‘Ir’ x L4: Displays the current balance and the % of leakage current The trip level is selected via the ‘Residual iTrp’ setting (Level 6, Screen 11) and is adjustable from 10% to 250% FLC and ‘off’. The trip time is selected via the ‘Res.trip time’ setting (Level 6, Screen 12) and is adjustable from 100ms to 5 seconds. Setting the trip level to ‘off’ disables this function. The residual current function can be used even if a core balance toroid is used for earth leakage protection. It can be used to provide some detection of wiring/CT/internal relay faults. 6.5 Under Current Trip Under current protection is enabled as soon as the main contactor is closed (indicated by closing the MCI input). Selecting a value of “None” will inhibit this function. If any phase drops below the selected trip setting for a period of 4 seconds then the outlet is stopped. This raises the “Under Current Trip” alarm and is recorded in the event log as “Und.I Trp”. To reset the relay, operate the reset button. The trip level is selected via the ‘Under I Level’ setting (Level 6, Screen 10). The trip level is selectable at 32%, 40%, 48%, 56%, 64%, 72%, 80%, 88% and 96%. Setting the trip level to “None” disables this function. This function is used when in snore mode and must be set to an appropriate level – note that there is a 4 second delay before a trip.

Failing to open when required. This is achieved by comparing the state of the main contactor (via the Main Contactor Input MCI) against the state of the MCR relay output. This test provides “Frozen Contactor Protection”. 2. Failing to maintain insulation across the contacts when the contactor is open. The Insulation Test Module (ITM) is used to measure the voltage on the load side of the contactor. If this exceeds 10% of the rated line voltage, a trip will occur. This test provides “Loss of Vacuum Protection”. This function is inhibited immediately after the main contactor opens to allow for back EMF voltages generated by some motors to dissipate. The inbuilt time is selected via the ‘back emf time’ setting (Level 6, Screen 20). The settings are adjustable from 2 to 20 seconds. A main contactor fail trip operates the CBR relay, which trips the circuit breaker. To reset the relay following a main contact failure trip, operate the reset key/digital input. The status of the MCI input can be viewed on the ‘IPM Relay and Keys’ screen, (Level 4, Screen 2). 7.2 Undervoltage Trip The undervoltage protection is enabled as soon as the main contactor is closed (indicated by closing the MCI input). If any of the phase voltages drop below the selected trip setting of the nominal line voltage for 800ms then the MCR relay is de-energised. To reset the relay following an undervoltage trip, operate the reset key/digital input. The trip level is selected via the ‘U/V Trp level’ setting (Level 6, Screen 19) and is adjustable from 40% to 95% in 10% increments. Setting the trip level to ‘off’ disables this function. 7.3 Voltage Metering The Insulation Test Module (ITM) is also used to provide line voltage metering. x L2: Displays the line current for each of the 3 phases. x L3: Displays the line voltages for each of the 3 phases. x L4: Displays the thermal accumulator and main contactor fail timer that counts down when a main contactor fault is detected. Line voltages of 415V and 1000V are configured when the appropriate Insulation Test Module is selected in the ‘Group 1 Settings’ (Level 5, Screen 2).

The output continuously monitors Average Current, Overload, Earth Leakage and the Insulation Level of the relay. The Monitor Output settings can be selected at ‘4-20mA Output’ (Level 6, Screen 28). Settings available are O/L (0-100%), Iave (0- 250%), E/L (0-100%) and MΩ (0-40MΩ). The analogue output status in milliamps is shown on the ‘IPM Relay and Keys’ screen, (Level 4, Screen 2). 8.2 Communications The IPM Relay provides an industry standard RS485 Slave Modbus communication port. This allows connection to a PLC or a SCADA system. Appendix 5 provides detail on Modbus addresses. The baud rate is selected via the ‘Modbus:Baud /P’ setting (Level 5, Screen 4) and is selectable between 1200 and 19200 Baud, with even, odd, or no parity. One stop bit is used in conjunction with parity, while two stop bits are used with no parity. The half-duplex 3-wire RS485 communications interface allows up to 31 devices to be multi-dropped onto a single master communication line. The IPM’s Modbus Slave address is selected via the ‘ModBus Addr:’ setting (Level 5, Screen 3) and is adjustable between 1 and 31. 8.2.1 Modbus Commands The following Modbus commands are supported: Modbus CMD Comment 03 Read Holding Registers 06 Store Single Register Valid read registers are in the range from 1 to 96. An attempt to read a register outside this range will result in an exception scan. Currently, only the first 78 registers contain valid data. Supported Modbus exception responses are: Modbus Exception Comment 01 Illegal Function 02 Illegal Data Address 03 Illegal Data Value 8.2.2 Modbus Status Status Comment Address The Modbus slave address the IPM is set to Read A solid block when a READ command is received Wrt A solid block when a WRITE command is received Exc A solid block when an unsupported Modbus command is received CRC A solid block when a checksum error is detected Par A solid block when a parity error is detected NE A solid block when noise is detected FE A solid block when a framing error is detected

Page 24 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 The Modbus Status can be viewed on Level 4, Screen 4. 8.3 IPM Alarm Functions The IPM has several standard alarm functions. If any are triggered, the Alarm Relay (ALM) picks up. Each has a selectable alarm level, and can be disabled. Generally the alarms are self-resetting once the alarm condition is removed. 1. High Current Alarm - Is activated by the phase currents exceeding the selected threshold. It is selected via the ‘High I alarm’ setting (Level 6, Screen 21) and is adjustable from 100% to 600% FLC and ‘off’. The highest of the three phase currents is used. Time delay = 1 sec. Setting the alarm level to ‘off’ disables this function. 2. Overload Alarm - Is activated by the thermal accumulator exceeding the selected threshold. It is selected via the ‘O/L Alarm Lev’ setting (Level 6, Level 22) and is adjustable from 50% to 95% and ‘off’. Time delay = 2 s. A motor overload trip overrides this alarm. Setting the alarm level to ‘off’ disables this function. 3. Under Cur. Alarm - Is activated by the phase current falling below the selected threshold. It is selected via the ‘Under I Alarm’ setting (Level 7, Screen 10) and is adjustable from 32% to 96% and ‘off’. This alarm is only activated when the motor is running (MCI input closed). Time delay = 2 sec. Setting the alarm level to ‘off’ disables this function. 4. Earth Leakage Alarm - Is activated when the earth leakage current exceeds a set level. The alarm level is selected via the ‘E/L Alarm Lev’ setting (Level 6, Screen 24) and can be set to 20%, 50%, 80% and ‘off’. The earth leakage alarm has a time delay of 1 second and auto resets when the earth leakage current falls below the selected level. Setting the alarm level to ‘Off’ disables this function. 5. Insulat. Test Alarm - Is activated when the meg-ohm resistance of each phase to earth, as a result of an insulation test, equals or falls below the alarm level. The alarm level is set at 1.5 times the trip setting. The alarm message is displayed until a new test is initiated or the key is pressed while displaying the alarm message. The ‘Insulat. Test Alarm’ is also recorded in the Event Log. 8.4 Fan Control 8.4.1 Burp Function The Burp Function of the IPM relay allows the progressive inflation of ventilation bags (tubes) by pulsing the motor contactor, controlling the ventilation fan, several times at start up (see Section 9.8.5 for operational sequence). There are three configurable parameters that control the Burp Function at start up, ‘Burp Number of Pulses’, ‘Burp Pulse On Time’ and ‘Burp Pulse Off Time’. Selectable Settings: x ‘# Burp Pulses’ (Level 6, Screen 25) - selectable at none and 1 to 6 (selection of “none” disables the Burp Function). x ‘Burp On Time’ (Level 6, Screen 26) and ‘Burp Off Time’ (Level 6, Screen 27) - selectable at 0.6, 0.8, 1.0, 1.2, 1.5, 2.0, 2.5 and 3.0 seconds.

Page 25 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 8.5 Snore Function The purpose of the IPM Snore Function is to, optionally, add a timed re-start to the IPM Relay after an undercurrent trip has been detected. Refer to section 7.5 for more information on the operation of the undercurrent trip function. 8.5.1 Basic Operation The basic operation of the snore function is illustrated using the following scenario: Assume a pump is the load device of the relay, which pumps a dam. When the pump has emptied the dam, its load current will drop significantly enough to be detected as an undercurrent trip (this level is set in the settings level 6) by the IPM. The Snore Function (snore-Process) will operate only after configuration and activation via the IPM menus. The snore function will operate after undercurrent is detected and will permit the pump to restart after a time delay (tSnoreDelay). After this off period the pump will restart. During the first 4 second ON period (tSnoreOn) the pump will run, and only if the pump remains in an undercurrent state, the IPM will extend tSnoreDelay by 1.5 times and switch off the output relay for the new setting of tSnoreDelay. This process will continue until the time reaches a maximum of tSnoreDelay x 8. The initial setting for tSnoreDelay is obtained from a menu configuration setting (tSnoreSet). The available initial settings are OFF, 5, 10, 15, 20, 8F, 15F, 20F, 30F, 60F minutes (the “F” represents a fixed delay that does not extend tSnoreDelay as described above. If a load is detected during tSnoreOn (that is, no undercurrent is detected), the pump will remain on, but tSnoreDelay will be reduced to ¾ of its present setting; but not below tSnoreSet (this does not apply to the “F” settings). In the case where the new tSnoreDelay is less than tSnoreSet, then tSnoreDelay shall be set to tSnoreSet. When in tSnoreDelay mode, and if a ‘Start’ stimulus from: a) The ‘Start’ key (on the relay), or, b) A pulse from the External Start is detected, then, the relay will immediately abort the running tSnoreDelay and proceed through a power- on sequence. If a power failure occurs when the IPM is operating in Snore Mode, it will resume operating in Snore Mode when power is restored. If Aux is open, or there is an EL fault on Power Up, the snore function will wait for up to 15 seconds to start. 8.5.2 Setup Procedure for Snore Function Setup of the Snore Function is done by settings throughout the menu structure. The additional settings required to enable the Snore Function include: x Start Mode must be set to ‘Snore’ x The Snore Delay parameter must not be set to none x The ‘Under Current’ trip level must not be set to none x The AUX External Digital input must be active. 8.5.2.1 Relay Snore Mode Starting Procedure When ‘Snore’ start mode is selected, the relay can be initially started from different sources: x Key button (‘Start’ button on the relay), if and only if digital input switch is ON, x External start button if and only if the digital input switch is ON. Each start stimulus with exhibit the following behaviour:

Page 26 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 x Key Button Start - Regardless of the status of the Snore Function, but with the digital input switch on, operation of the ‘Start’ key will cause the relay to proceed through a power-on sequence. x External-Start switch - When this switch is closed the relay will start a power-on sequence on cold boot. The digital input switch must be on if it is open, then the relay cannot be started in Snore Mode. 8.5.2.2 Relay Stop Procedure x The relay will be stopped whenever the Stop key or the external Stop is actioned – regardless of the Snore process. This will reset the delay. x If the AUX input opens at any time during operation in Snore more, then a start is required to restart the snore function. The Message ‘Snore – Need Aux’ will be displayed on the screen when in Snore mode with the AUX open. This will reset the delay. 8.6 Remote IPM Control The IPM and RTM software have been changed to allow for the RTM digital input to be used to control the IPM. This functionality is similar to that of the IPB/C/D. The remote start can be set in two modes. In one mode it is always active and in the other mode it is active only when the auxiliary digital input is closed. Remote start can also be disabled. 8.6.1 Function Overview A previously unused parameter called ‘remote start’, originally intended to implement the remote start functionality, is used to enable the remote start function. Setting it to ‘yes’ enables remote start. Setting it to ‘no’ will disable remote start. Setting it to ‘Aux’ enables remote start only when the auxiliary digital input is closed. The remote input (on the RTM) is edge sensitive. This ensures that if there is an upstream trip, the IPM will not restart automatically once the power is restored. It also allows the keypad and external digital input stops to work sensibly so that if the IPM is stopped locally, it will not restart immediately after any of the stop are released. When remote start is active, the remote input is closed to start the IPM and must remain closed while the IPM is running. The remote input is opened to stop the IPM. 8.6.2 Operating Modes The external digital stop input and the keypad stop will always stop the IPM regardless of the start mode. There are two modes in which the IPM relay can operate: x Diode Mode- The remote start parameter has no effect when the IPM is set to diode mode. x RTM Mode- The Remote start parameter has three possible options; ‘no’, ‘yes’ and ‘aux’. 8.6.2.1 Remote start - ‘no’ The remote input will be ignored. Starting the relay will depend on whatever start mode is selected as per the existing operation.

Page 27 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 8.6.2.2 Remote start - ‘yes’ 1. Start mode - ‘K/Ext’ (Keypad or External) Keypad and External start inputs are ignored. Remote input controls the IPM. Local stop input will still stop the IPM. Local stop inputs will override the remote start if they are held closed while a remote start is signalled. 2. Start mode - ‘Ext’ (External only) As per ‘K/Ext’ 3. Start mode - ‘K&Ext’ (Keypad and External) As per ‘K/Ext’ 4. Start mode - ‘Modbs’ and ‘Snore’ These modes will not operate when remote start is set to ‘yes’. The status display will show “Configuration Err”. 8.6.2.3 Remote start - ‘Aux’ When an appropriate start mode is selected, changing the Auxiliary digital input will switch between local (keypad or external digital start input) and remote (RTM digital input). It is allowable to change the state of the Auxiliary input while the IPM is running. If the RTM input is open and the IPM is running while the Auxiliary input is closed, the IPM will immediately stop. If the RTM input is closed and the IPM is running while the Auxiliary input is closed, the IPM will continue to run. 1. Start mode - ‘K/Ext’, ‘Ext’ and ‘K&Ext’ The IPM will change between remote start mode and local start mode depending on the state of the ‘Aux’ digital input. When the input is close the IPM will be controlled via the RTM as described in section 9.6.2.2. When the ‘Aux’ digital input is open the control will revert to local mode. The start signal required will depend on the Start mode parameter. 2. Start mode - ‘Modbs’ and ‘Snore’ These modes will not operate when remote start is set to ‘yes’. The status display will show “Configuration Err”. 8.6.3 IPM/RTM Software Compatibility A ‘New IPM’ is considered to be version 9 or earlier; An ‘Old RTM’ is version 2 or earlier (reported as ‘20’ on the IPM display). x New RTM and New IPM - Nothing to consider x New RTM and Old IPM - The Old IPM will ignore the remote start setting. x Old RTM and New IPM - The new IPM will check the version of the RTM (this is transmitted in the pilot protocol). If the RTM has the ‘remote start’ parameter set, but the RTM version is too old, the IPM will display “RTM Version Error”. x Old RTM and Old IPM - Nothing to consider 8.6.4 Status Messages There are two new status messages - “Need RTM Start” and “Remote Stop”. When in remote start mode, whenever the RTM’s digital input is open, the display will show “Remote Stop”. If the digital input is closed but the IPM is stopped the display will show “Need RTM Start” to indicate that the RTM’s digital input needs to be opened and then closed to generate a new edge.

Page 28 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 This is most likely to happen if the RTM’s digital input is closed to allow the IPM to run and then a local stop is used to stop the IPM. Because of the edged triggered nature of the RTM digital input, the IPM will not automatically restart. 8.7 Adjustable Settings 8.7.1 Parameter Groups There are two groups of adjustable settings contained in the IPM relay’s non-volatile memory. Both groups can be viewed and modified via the display and the up/down and left/right keys. The first group of settings is always stored in the relay and relates to parameters, which are linked to the system rather than the particular load connected to the outlet. Group 1 Setting Description EC Pilot Mode Determines if the pilot is to be terminated with a diode or Remote Termination Module ITM Module Selects the Insulation Test Module to be used with the IPM Relay Start Mode Selects the inputs required to initiate a start condition ModBus Address Selects the Modbus Slave Address ModBus Baud/P Sets the Modbus baud rate ModBus Timeout Sets ModBus Error timing CT RATIO Selects between 100:1 and 1000:1 toroids The second group of settings consists of parameters that are related to the load connected to the protected outlet. These settings are stored, retrieved to/from the memory in the IPM Relay or the memory in the Remote Termination Module, depending on the “Pilot Mode” setting. If a diode pilot mode is selected the IPM Relay reads and writes to and from the relay’s internal memory for the group 2 settings. If an RTM Mode is selected the settings are sent to and retrieved from the memory in the Remote Termination Module. Group 2 Setting Description RTM Mach. Type Selects the RTM descriptive code transmitted to identify the machine connected to the outlet RTM Mach. Num Selects the assigned machine number to be transmitted by the Remote Termination Module 100% Current Sets the full load current OC I mul Combines with OC range to define the full load current Short Cct.

The EC Pilot Mode should be checked prior to making any other adjustments to be certain the changes are made to the desired memory. x Ensure the outlet is stopped. x For Group 2 Settings in RTM Mode, ensure RTM is on line. x Display the parameter that has to be changed. x Close the lock input. x Press the enter button to change the current parameter. x Use the left and right arrows to step through the allowable values until the desired new setting is displayed. x Press the enter button to indicate that the value is the required setting. x Open the lock push input. If the ESC key is operated at any stage during the procedure, the modifying sequence is aborted and the setting reverts to its previously stored value. When changes have been made to the stored values, the old value and the new value are stored in the event log.

To activate an input a connection needs to be made from '+DiPwr' terminal to the respective digital input’s terminal. x L2: Displays the status of the external reset and the lock inputs. x L3: Displays the status of the external stop and the auxiliary inputs. x L4: Displays the external start input and the analogue output in mA. The function of each input is as follows: 1. Lock: The lock input needs to be closed while ever changes to the relay settings are being made. If the lock input is not closed then the settings cannot be changed. 2. The lock input must also be closed to reset the thermal memory to allow an emergency restart. To perform a reset, the motor must be stopped (MCI open) and both the reset key and the lock input must be held closed for 1.5 seconds. This will reset the ‘Thermal Accumulator’ and allow the motor to be started immediately 3. Reset: The reset digital input performs the same function as the keyboard reset allowing for external/remote resetting of trips. To reset a trip an open to close transition on the reset input (or reset key) is required. 4. MCI: The Motor Contactor Interlock input provides the IPM relay with the status of the motor contactor. Its status is used by the thermal modelling to activate the 'Cooling Multiplier' and also provides the basis for Motor Contactor Fail (MCF) monitoring. 5. Digital: This is an auxiliary digital input. 6. Ex-Start: This input allows the installation of an external start button. 7. Ex-Stop: This input allows the installation of an external stop button. 8.8.2 Output Relays The IPM provides three relay outputs for correct operation. All relay contacts are rated at 5A/190VAC. 1. MCR: (Main Trip Relay). This relay energises when there are no trips, and drops out whenever a trip occurs. A normally open and a change over set of contacts are provided. 2. ALM: (Alarm Relay). This relay energises whenever there are alarms active and drops out when all alarms are clear. One changeover set of contacts is provided. 3. CBR: (CBR Relay). This relay is normally energised and drops out if there is a short circuit trip or a motor contactor fail trip. One changeover set of contacts is provided. x L2: Displays the status of the CBR and MCR Relays. x L3: Displays the status of Alarm Relay, the Test key and the Main Contactor input. x L4: Displays the status of the Start, Reset and Stop Keys.

Page 31 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 8.8.3 Outlet Control The outlet can be energised by local or remote operation depending on the ‘Remote Start’ option. The selection is “Yes” or “No” (Level 6, Screen 16). If “Yes” is selected the relay ignores the local start input thus allowing operation of the outlet from the remote machine. Both the external and local stop buttons will turn off the outlet. If “No” is selected the local start/stop buttons control the outlet. 8.8.4 Start Mode The Start Mode is selected at (Level 5, Screen 3). The possible settings are K/Ext, Ext, K&Ext, Modbus and Snore The start/stop logic operates as follows: 1. The external stop digital input and the front keypad stop button will always stop the relay, regardless of the settings for ‘Start Mode’. In all cases only one of the stop inputs needs to be active to stop the relay. 2. K/Ext mode – Relay can be started with either an external start or the keypad 3. Ext mode – Only the external start is used. The keypad start is disabled 4. K&Ext mode – Both the external start and the front panel keypad start button needs to be active to start the relay. 5. Modbus mode – Not implemented 6. Snore mode – The parameters for Under Current Trip, Start Mode and the Snore time delay need to be set for your application. Extra protection against accidentally selecting this mode is provided by requiring the external digital input to be closed before this mode will start. 8.8.5 Operational Sequence (Insulation Test and Burp Function selected) Before an outlet can be energised there should be no protection faults present. Once the start button is operated an insulation test is performed. If the result of this test is satisfactory the Burp Phase is initiated. When the Burp Phase is completed the IPM Relay goes into the run mode. A time delay of 5 seconds is allowed for the Main Contactor Interlock (MCI) to close. If it does not close within this time, then the run mode is exited. If a stop input is closed while the relay is in run mode, the run is cleared, and the MCR relay de- energises. The event log reads “Stopped”. While the main contactor is closed, the MCI input is continuously monitored. If it opens, the run is cleared and the MCR relay de-energises. In this case the event log records “MC Opened” which indicates that the outlet was turned off by something other than the IPM Relay, for example, open circuited main contactor coil or control supply. It should be noted that if the main contactor does not close when the MCR relay closes and the start/stop conditions are maintained, then the IPM will cycle through the following start sequence: testing, run, stopped, pause then repeat the sequence while ever the start input is closed. 8.9 Event Log A real time clock/calendar is included in the IPM Relay. This combines with the non-volatile memory to provide a data-logging feature. This log sequentially records the time, date and details of the most recent event. A chronological list of the previous 50 events is stored. The event log can be viewed by using the right or left arrow keys to scroll the log.

This manual does not cover system commissioning; the full scope of commissioning tests should be determined during the risk assessment or FMEA covering the design of the electrical protection system. 9.2 Equipment Service The IPM V2 requires no internal servicing during its normal operating life. A number of external system based checks should however be completed on a regular basis. These ‘routine inspections’ must be carried out by suitably trained people with knowledge of the relay and the systems into which it is fitted. Routine inspections may take the form of either visual-only checks, or visual and ‘hands-on’ checks. 9.2.1 Visual Only Inspections A basic visual inspection focuses on looking at the installation for signs of physical damage, water or dust ingress and the condition of cables and labels. This type of inspection may involve opening cabinets to gain access to the IPM V2 and other equipment. This level of inspection may also include cleaning display windows that have become obscured by dirt. Observations would typically be: x Check that equipment enclosures, cable trays, conduits, etc. are in good order with no physical damage. x Check that sealed wall boxes are free from water and dust ingress internally. Door seals are in good condition. x Check that connected cables are free from cuts, abrasions and obvious signs of damage. Cable restraints are in good order and correctly fitted. x Check that labels on equipment, wall boxes and cables are present and in good condition (especially certification labels). x Check that no modifications have been carried out to installed equipment. 9.2.2 Hands-On (Detailed) Inspections A more detailed inspection would include all of the elements of a visual inspection, plus some checks that cover the integrity of connections, fixtures and fittings. In addition to basic visual observations, more detailed integrity checks would involve: x Verify that equipment housings, wall boxes and other mechanical fixtures are secured in place. This includes terminal box lids, tightness of cable glands, integrity of wall-box mountings, security of equipment fixing to walls/DIN rails etc. x Verify all electrical connections are secure with no loose screw terminals or DIN rail terminals not fitted to rails etc. 9.3 Equipment Maintenance WARNING! The IPM V2 relay has no user-serviceable parts. All repairs must be carried out by Ampcontrol only. If a fault develops, return the relay to Ampcontrol for repair. It is essential that no attempt be made to repair the IPM V2 as any attempt to dismantle or repair the relay can seriously compromise the safety of the unit.

Page 35 of 37 Ampcontrol Electronics Pty Ltd – ABN 35 000 770 141 IPM2B003 IPM V2 User Manual Rev 12 – 08/14 It is recommended that the electrical protection system incorporating the IPM V2 be subject to regular functional tests at intervals determined by risk assessment or FMEA. These intervals typically coincide with periodic maintenance checks and will cover (but not limited to) tests such as earth continuity tests. 9.4 Disposal The electronic equipment discussed in this manual must not be treated as general waste. By ensuring that this product is disposed of correctly you will be helping to prevent potentially negative consequences for the environment and human health which could otherwise be caused by incorrect waste handling of this product.
