Fault Conditions
The motor is designed to protect itself in the event of a fault condition. Should the motor encounter a
fault, the Error light on the integrated UI illumines and the LCD displays basic information related to the
problem. Fault conditions are of two general types.
·
Self-Clearing (SC)
–
You cannot cancel a Self-Clearing fault condition. The source of the fault must
be corrected before the fault is cleared from the UI display. For example, if a module over
temperature fault is detected, the module temperature must decrease to an acceptable level before
the fault clears. The
Retry Count
on a self-clearing fault cannot be reset by the user.
·
Not
Self-Clearing
–
Fault conditions that are not self-clearing will retry a set number of times at
specified intervals. After all retry attempts are exhausted, the motor will stop. If the fault condition
permits a
User Reset
of the
Retry Count
, pressing
Start/Pause
resets the
Retry Count
back to
zero (0) and allows the motor to attempt running again.

Overcurrent (HW)
Self-Clearing (No), Retry Count (15), Retry Delay (12 Seconds), User Reset (Yes)
Motor phase current is the input current enabling the pump to run at or under a specified speed or
torque. Phase current over the peak threshold will trigger an Overcurrent (HW) fault. The pump will
shut down and restart automatically. Then, the motor will cycle through the shutdown/restart
sequence the number of times specified in the Retry Count to correct the fault condition. At the end
of the sequence, if the fault has not corrected itself, the motor will not restart.
The fault condition can be triggered by the motor, the control. or the pump system. Press the
Start/Pause
button to clear the fault from the LCD display. Then, press any
Speed
button to restart
the motor. The retry sequence will start over. If the fault continues to occur, contact your pool
professional or a qualified electrician for service.

Low Voltage
Self-Clearing (Yes), Retry Count (15), Retry Delay (12 Seconds), User Reset (No)
The voltage to the motor/control terminals must be either 115 or 230 Vac, (depending on the option
you set with the Voltage Selection Switch) +/- 10 percent, 60 or 50 Hertz. A sustained input voltage
significantly below the chosen voltage setting will cause a Low Voltage trip to occur.
When the fault occurs, the pump will shut down and automatically restart when operating conditions
are within specifications. The pump will cycle through the shutdown/restart sequence the number of
times specified in the Retry Count to correct the fault condition.
When the input voltage returns to a normal state, the fault automatically clears and the motor
restarts. If the fault continues to occur after verifying input line voltage is correct, contact your pool
professional or a qualified electrician for service.

Hot Power Module
Self-Clearing (Yes), Retry Count (0), Retry Delay (0 Seconds), User Reset (No)
The power module is an integrated circuit in the motor control. Software in the control continuously
monitors the temperature of this component. If the temperature in the power module exceeds a
specified threshold, the motor stops in order to prevent the power module from overheating and
causing damage to the motor.
After the temperature in the power module drops below the threshold number, the pump
automatically restarts and clears the fault from the LCD display.
