Fault Message
Possible Cause
Solutions
Flashing
Parameter 007 or perform the
auto calibration sequence
Pump calibration has not been
completed.
See Pg 6 for calibration
instructions.
Flashing
Parameter 004 and 008
Water level in the well/sump is
below pump intake, pump stops
running.
Broken outlet pipe
iPROTECT will attempt to
restart the pump every 30
minutes until water level
restored.
Flashing
Parameter 005 and 009
Pump running amps greater than
calibrated running amps, pump is
in overload protection state.
Pump damage, dragging impeller
or bearing, possible clogging.
Pump calibrated without water or
with a nominal kW value
iPROTECT will attempt to
restart the pump every 30
minutes until running amps
restored to normal.
Inspect and/or repair pump.
Erase previous calibration
and recalibrate with water.
Flashing
Parameter 010
Pump running amps greater than
200% of calibrated running amps
Pump Stalled protection is especially
important for pumps with cutting or
macerating mechanisms
Cut off power supply,
inspect, repair or replace
pump.
Flashing
Parameter 011
Voltage is lower than the
calibrated voltage.
The pump is in under voltage
protection state.
iPROTECT will attempt to
restart the pump every 5
minutes until normal
voltage is restored.
Flashing
Parameter 012
Voltage is higher than the
calibrated voltage.
The pump is in the over-voltage
protection state.
iPROTECT will attempt to
restart the pump every 5
minutes until normal
voltage is restored.
Flashing
Pump starts more than 5 times
per minute.
It is less likely that this could
occur in drainage or transfer
mode unless there is a wiring
fault.
Check pressure switch
settings are correct for
application.
Check pressure tank pre-
charge pressure and
condition of diaphragm.
Check the volume of sump
is not too small.
Flashing
The jumper on temperature
protection terminals has been
removed.
Pump motor temperature high
and pump thermal switch in open
state (if connected).
Reinstall jumper on
temperature protection
terminals.
Wait until pump motor
temperature reduces.
Investigate cause for
Overheating.
