Motor Drive Faults

The display on the motor drive located inside the electrical enclosure alerts

the operator to abnormal motor drive/motor operation. Motor drive faults

cause the pump to stop, refer to the motor drive Error Messages given later.

To clear a motor drive fault, correct the problem that caused the fault and

then remove power from the motor drive by turning the heaters off and wait

until the motor drive display is completely blank.
