Description
This fault can be caused by:
• Mechanical binding from debris in pump.
• Electrical failure of the motor.
• Incorrect setting of Motor Overload Setting switches.
• Incorrect rotation.
• Motor phase loss.
This fault will be displayed if the output current exceeds 125% of the
controller rating. The controller will attempt to restart 5 times. If the
condition persists the controller will lock out and will need to be reset.
Verify the error by turning power to controller off for 5 minutes and
then on. Pump/Motor/Wiring must be checked if fault persists.
This fault can be caused by:
• Electrical failure of the motor
• Electrical failure of wiring between controller and motor.
This fault will be displayed if the output current exceeds 150% of the
controller rating. 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 5 minutes.
Remove the three motor wires from the terminal block. Check output
wiring and motor for shorting phase to phase and phase to ground.
Refer to motor's manual for information on resistance readings and
megger readings.
This fault can be caused by:
• Disconnected input power phase.
• Incorrect Motor Overload Setting switches. When using single
phase input power the Motor Overload Setting switches must be set
to 50% or lower.
For three phase input operation; this fault will be displayed if the
phase to phase input voltage is more than 25% lower than the
nominal. The controller will attempt to restart 5 times. If the
condition persists the controller will lock out and will need to be reset.
This fault can be caused by:
• High ambient temperature. The maximum ambient temperature
rating is 122 ºF (50ºC).
• Low ambient temperature. The minimum ambient temperature
rating is -22ºF (-30ºC).
This fault will be displayed if the ambient temperature is greater than
122ºF (50ºC) or less than -22ºF (-30ºC). Do not install the controller
where it will be exposed to direct sunlight. Check for a fan failure. The
fans on the back of the controller will turn on only when needed. The
fans will turn on when the motor is running and the heatsink
temperature reaches 104 ºF (40ºC).
