What would cause the ATS46 to go out on overcurrent?
The Fault code is OcF: Possible Causes are: * High impedance short circuit at the output of the controller * Internal short circuit * Improper sequence of shorting contactor
Possible Corrective action: Remove power from unit and check for: -Damage to power cables and/or motor insulation -Damage to thyristors -Damage to shorting contactor/contactor stuck in closed position
If none of the obvious is seen then --identify exactly when the fault is occurring in relation to startup -- identify what In, ILt and acceleration are set for -- identify what is the full load amperage of motor -- and determine the currents being pullin in the LCR parameter of starter.
After obtain this information contact PSG for further assistance.
