4. Check that the auxiliary/ control supply is as expected:
Measure and record voltage between Line and Neutral.
•
• Measure and record voltage between Line and Earth.
5. Check that Neutral is properly earthed (at least at the LV supply transformer, but
preferably at the main distribution board also).
6. Measure and record voltage between Neutral and Earth.
Check the bypass readback input (C73, C74) on the power interface board (volt free).
•
• Voltage at all electronic power supply connectors must be 26.5 VDC.
Voltage for the contactors (at the connector block) must match the voltage for the
•
contactor coil circuit, as specified on schematic diagrams.
7. Connect the 24 VDC connector to the power interface board. The power supply LED
should illuminate and the fibre-optic TX LED should flash.
8. Connect the 24 VDC connector to the controller. The start-up message should be
displayed on the LCD.

Motor simulation

Use the MVE Simulation functions to ensure that the starter is connected correctly to the associated equipment.
1. Disconnect the soft starter from the mains supply.
2. Set the date and time and all necessary parameters.
3. Reset all performance counters.
4. Operate the Run Simulation using the keypad on the controller.
• Check that the relays on the power interface PCB operate and activate the MV
contactors.
• Check that the firing signals are received at the gate drive board.
Check that the LEDs on the power interface board, gate drive boards and firing
•
boards activate as expected at each stage of the simulation. Refer to
on page 22 for more details.
5. Operate the Protection Simulation and confirm that the starter responds as expected.
6. Operate the Output Signal Simulation and confirm that the starter provides output
signalling as expected.
7. Confirm that the soft starter trips if the thermistor is not present.
Low voltage motor test

Use the soft starter's low voltage test function to confirm that the soft starter can control a motor.
NOTE
The FLC for the low voltage motor must be ≥ 5 A (refer to parameter 1A
value for parameter 2D
NOTE
Models V06~V13 require an LV motor test resistor assembly (part number 995-03946-00). The LV motor test
resistor assembly is not required for low voltage testing of V02~V04 models.
8. Disconnect the soft starter from the mains supply.
9. WARNING
Attach one motor test resistor assembly to each phase arm. (See below)
10. Connect the soft starter to a low voltage mains supply and a low voltage motor.
