What to do if my AuCom MVE Controller shows a heatsink overtemperature?
If the AuCom Controller indicates a heatsink overtemperature, it means the soft starter is operating at a dangerously high temperature. Ensure that the ventilation and cooling systems are working correctly. You can also reduce the number of consecutive starts by increasing the value set in parameter 4M Restart Delay.
What to do if AuCom MVE shows an instantaneous overcurrent?
If the AuCom Controller displays an instantaneous overcurrent, it indicates a sharp rise in motor current, possibly due to a locked rotor or a medium level fault current. You should identify and resolve the cause of the fault.
What to do if my AuCom Controller indicates a motor overload?
If the AuCom Controller shows a motor overload, it means that the motor has reached its maximum thermal capacity, potentially due to excessive starts or current. You should resolve the cause of the overload and allow the motor to cool down.
What to do if AuCom MVE Controller displays 'Ground fault'?
If the AuCom Controller displays 'Ground fault', it means ground current has exceeded the selected level. You should test the insulation of the output cables and the motor to identify and resolve the cause of any ground fault.
What to do if my AuCom Controller shows an undervoltage?
If the AuCom Controller indicates an undervoltage, it means the mains voltage has fallen below the level selected in parameter 4Q. Check that the starter is configured appropriately for local conditions and monitor the mains voltage to determine and resolve the cause of the voltage fluctuation.
What to do if AuCom MVE displays 'Excess start time'?
If the AuCom Controller displays 'Excess start time', it means the motor couldn't accelerate to full speed in the allowed time, possibly due to parameter settings or increased loading. Resolve the cause of the overload.
What causes a frequency error on an AuCom MVE?
If the AuCom Controller shows a frequency error, it means the mains frequency is beyond the specified range. Check for equipment affecting the mains supply, like variable speed drives and SMPS. If connected to a generator, ensure the generator is adequate and has proper speed regulation.
What to do if AuCom MVE displays 'Bypass fail'?
If the AuCom Controller displays 'Bypass fail', it means the bypass contactor has welded closed or isn't operating correctly. Inspect the bypass contactor's main poles and check the contactor control circuitry and coil operation.
What to do if AuCom Controller displays 'Int Comms Fail'?
If the AuCom Controller displays 'Int Comms Fail', it means communication between the controller and the power interface board has failed. Verify the controller is receiving control voltage within the specified range (terminals A11, A12). Check that the fibre-optic cables between the controller and the interface board are firmly connected and emitting light at the Rx end.
What to do if AuCom MVE Controller displays 'EEPROM fail'?
If the AuCom Controller displays 'EEPROM fail', it means an error occurred loading data from the EEPROM to RAM when the controller powered up. Reset the fault and then reload the default settings. If the problem persists, contact your local distributor.
