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.
