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 Table 9-4 for the motor drive fault codes.
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.
