Temperature sensor fault
of pump motor controller
1. Motor temperature
sensor fault;
2. Setup error of motor
temperature sensor
type
1. Check the wiring of motor temperature
sensor;
2. Check the setup of motor temperature
sensor via programme/motor menu/
temperature control sensor type.
3. Replace the motor temperature sensor.
Note:The pins #7 and #8 of the 35–pin
controller connector are for motor temperature
sensor.

Open/short-circuited drive
1 output/main contactor of
pump motor controller
1. Driver 1 wiring fault;
2. Loading device fault;
3. Contactor fault.
1. Ensure the correct wiring and the pins free
of stains or damage;
2. Monitor output signal via monitor menu/
outputs menu/Driver 1 PWM to check
whether there is output control signal;
3. Check the coil of contactor;
4. Replace the contactor.
Note:The pins #6 of the 35–pin controller
connector is for driver 1 output.
