TROUBLESHOOTING
RUN LIGHT CAL LIGHT PROBLEM or FUNCTION CORRECTIVE ACTION
On Steady Off
RUN:
Pump is running—or ready to run—no
problems in operation
If pump is not running, check for
loose wiring and ensure proper
function of pressure or float
switches.
On Steady On Steady
CAL: The PumpSaver
®
is in the
calibration process.
None
Off On Steady
CAL COMPLETE:
The PumpSaver has calibrated, the
RESTART DELAY/ CALIBRATION
knob was left in the CAL position.
Pump is off.
Pump will restart as soon as the
RESTART DELAY/ CALIBRATION
knob is rotated out of the CAL
position.
Off Off
OFF / MANUAL RESTART: The pump
is not running. Either the PumpSaver
®
has tripped on dry-run, dead-head, or
overload while the RESTART DELAY/
CALIBRATION knob was in the
RESET position or source power is not
present.
If knob is in the RESET position,
rotate out of RESET—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.
Blinking Off
DRY RUN / DEAD HEAD:
The PumpSaver
®
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.
Check for restricted flow or
inadequate supply of liquid.
Off Blinking
OVERLOAD:
The PumpSaver
®
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.
Check for low or high voltage or
jammed pump impellers. If these
conditions do not exist, recalibrate
the unit while it is drawing higher
current (amps should not exceed
SFA).
Blinking
alternately
with the CAL.
LIGHT
Blinking
alternately
with the RUN
LIGHT
VOLTAGE FAULT:
The PumpSaver
®
is preventing the
pump from starting due to voltage
problems. The voltage is being
interrogated and the unit will remain in
this mode until the voltage is at an
acceptable level. If the unit remains in this state for
more than 5 seconds, check for
high or low voltage.
Blinking in
unison with
the CAL.
LIGHT
Blinking in
unison with
the RUN
LIGHT
RAPID CYCLE: The PumpSaver
®
has
shut down on rapid cycling. Power
must be removed and reapplied to
reset the unit.
Check for a broken bladder in the
pressure tank (if used), or check
for a defective pressure or float
switch.
