Problem Or Function
RUN: Pump is running, no problems in operation.
CAL: The motor protector is in the calibration process
CAL COMPLETE: The motor protector is calibrated,
RESTART DELAY / CALIBRATION pot was left in "CAL."
position. Pump is off.
OFF / MANUAL RESTART: The motor is not running.
Either the Motor protector has tripped on dry run,
dead head, or overload while the RESTART DELAY
/ CALIBRATION pot was in the "RESET" position, or
source power is not present.
DRY RUN / DEAD HEAD: The motor protector has shut
the pump off due to a dry run or dead head condition.
The unit is timing through the restart delay and will try
to restart.
OVERLOAD: The motor protector has shut the pump off
due to an overload condition. The unit is timing through
the restart delay and will try to restart if line voltage is
at an acceptable level.
VOLTAGE FAULT: The motor protector is preventing
the pump from starting due to voltage problems. The
voltage is being monitored and the unit will remain in
this mode until the voltage is at an acceptable level.
RAPID CYCLE: The motor protector has shut down on
rapid cycling. Power must be removed and reapplied to
reset the unit.
Corrective Action
None
None
Pump will restart as soon as the RESTART DELAY /
CALIBRATION pot is rotated out of the "CAL." position.
If pot is in the "RESET" position, rotate out of that
position. If the "CAL" light blinks, check for an overload
condition. If the RUN" light blinks, look for a dry run
or dead head condition. If no lights come on, check
incoming power for adequate voltage.
Check for restricted flow or inadequate supply of liquid.
Check for low or high voltage or jammed pump
impeller. If these conditions do not exist, recalibrate
the unit while it is drawing higher amps (Amps should
not exceed SFA).
If the unit remains in this state for more than 5
seconds, check for high or low voltage.
Check for broken bladder on the pressure tank (if
used), or check for defective pressure or float switch.
