3 Blinks Sensor Fault
(continued)
4 Blinks Over Current This fault can be caused by:
• Installing a 1Ø motor - system requires a 3Ø, 200 or 230 V motor.
• Mechanical binding from debris in pump.
• Electrical failure of the motor.
• Incorrect setting of “MOTOR OVERLOAD SETTING (SFA)” switch.
A false “bound pump” error will be displayed if the switch is set too low.
• Pump wire insulation breaking down. Check insulation with megger.
Verify the error by turning power to controller off for 1 minute and then on.
Pump/Motor must be checked if fault persists.
5 Blinks Short Circuit This fault can be caused by:
• Electrical failure of the motor.
• Electrical failure of wiring between controller and motor.
Verify the error by turning power to controller off for 1 minute and then on.
If error persists, motor and wiring between controller and motor must be
checked. Turn power off for 1 minute. Remove the three motor wires from the
terminal block. Check wiring and motor for shorting phase to phase and
phase to ground. Refer to motor’s manual for information on resistance
readings.
