Motor Overload
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.
The controller will protect the motor from over current by limiting the cur-

reduced to limit the current to the motor by more than 10Hz for 5 minutes.
