Temperature sensor fault of
pump motor controller
1. Motor temperature
sensor fault;
2. Motor temperature
sensor type setup
error.
1. Check the wiring of motor temperature
sensor;
2. Check the setup of motor temperature sen-
sor (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 driver 1
output/main contactor of
pump motor controller
1. Driver 1 wiring fault;
2. Loading device fault;
3. Contactor fault.
1. Check if the wiring is correct and pins are
stained or damaged;
2. Monitor output signal (monitor menu/out-
puts menu/Driver 1 PWM) to check
whether there is output control signal;
3. Check the coil of contactor;
4. Replace the contactor.
Note: The pin #6 of the 35-pin controller
connector is for driver 1 output.

Open/short-circuited driver 2
of pump motor controller
1. Driver 2 wiring fault;
2. Loading device fault;
3. Contactor fault.
1. Check if the wiring is correct and pins are
stained or damaged;
2. Monitor output signal (monitor menu/out-
puts menu/Driver 2PWM) to check
whether there is output control signal;
3. Check the coil of contactor;
4. Replace the contactor.
Note: The pin #5 of the 35-pin controller
connector is for driver 2 output.

2. Stained/damaged/bro-
ken wiring.
1. Check if the wiring is correct and pins are
stained or damaged;
2. Monitor output signal (monitor menu/out-
puts menu/Driver 3 PWM) to check
whether there is output control signal;
