FAULT
TRIGGER
POSSIBLE CAUSES
POSSIBLE SOLUTIONS
Over Current
The device is behaving like
and ammeter and indicating
that it is drawing greater than
the programmed SFA after
initial motor start.
Shorted motor wires - line to line
Check line to line resistance (Ohms) and confirm
they match motor specifications. (Rx1 scale)
Shorted motor wires - line to ground
Damaged wire insulation. Check motor wire
insulation with a megger. Recommend a meter
that can read values 2,000,000 Ohms or more.
Dry run
Default setting: If the
pressure in the system drops
below 10psi for 15 seconds,
the device faults. NOTE:
Dry Run is based solely on
the ability of the system to
maintain pressure. It is not
based on Amps.
Over pumping the well.
Check water level in the well.
Operation at open discharge so the
transducer does not see the required
10psi of back pressure.
To operate continuously at open discharge, lower
Sensitivity (detection pressure). Setting to 0
essentially turns Dry Run off.
To operate intermittently at open discharge, set
Detection Time to exceed the open discharge run
time.
Locked Rotor
The pump motor is drawing
higher amps than expected.
The value for Service Factor Amps
in the App may be incorrect.
Verify that the value for Service Factor Amps has
been entered properly in the app.
The motor is stalled and can not turn the
pump.
Check for debris stuck in the pump.
The device is behaving like
and ammeter and indicating
that it is drawing greater than
the programmed SFA after
initial motor start.
Shorted motor wires - line to line
Check line to line resistance (Ohms) and confirm
they match motor specifications. (Rx1 scale)
Shorted motor wires - line to ground
Damaged wire insulation. Check motor wire
insulation with a megger. Recommend a meter
that can read values 2,000,000 Ohms or more.
Over Pressure
System pressure exceeded
the Over Pressure limit set in
the device.
Setpoint changed to be too close to
Over Pressure setting.
Recommend at least a 10psi difference between
setpoint and Over Pressure setting.
Water treatment installed between device
and tank causes water hammer. As flow
through the water treatment decreases, the
tank is isolated and water hammer
may happen.
Locate device and tank before all water
treatment.
Check valve located between tank and
device. This allows pressure to build up from
thermal expansion of hot water heater.
Remove or relocate check valve.
No tank in system causes water hammer.
Add an appropriate tank.
Waterlogged tank causes water hammer.
Check tank and replace if necessary.
Tank too small for system capacity causes
water hammer.
Add an appropriate tank.
Excessive Run Time
The system ran continuously
for longer than the Excessive
Runtime Hours setting.
Leak in the system.
Check for leaks in pipe system.
Short Cycle
The system is running for a
shorter time than it should.
Waterlogged tank.
Check tank and replace if necessary.
Current Sensor
Fault
The system is running but the
controller is not detecting
any current draw.
Broken motor lead.
Verify that all motor wires are free from damage
and that all connections are secure.
The thermal protector in the motor is open.
Wait for 20 minutes then try to restart the motor.
Pressure Sensor
The pressure sensor is not
working properly.
The sensor was damaged by either a
significant pressure spike or power surge.
Replace the entire device.
