Troubleshooting
Problem
Cause
Solution
The unit doesn’t work and the power-
•
on light is off, even after connecting
the supply voltage and selecting
“AUTO” mode.
Wrong input connection.
•
Phase failure.
•
Over-voltage supply.
•
Connect accurately.
•
Check the three phases.
•
Verify and measure the supply voltage.
•
Pump OVERLOAD alarm trips.
•
Excessive motor consumption.
•
Low overcurrent adjustment.
•
Input phase failure.
•
Verify the pump. The pump motor is overloaded.
•
Check the motor consumption and adjust the current.
•
Check the three supply phases.
•
Pump UNDERLOAD alarm trips.
•
Low current consumption <1,5 A.
•
Input phase failure.
•
Motor not connected.
•
Check the pump (no water in suction, stuck pipe,
•
etc...).
Check the three supply phases.
•
Connect the motor.
•
The pump doesn’t re-start.
•
Re-start time is set to “0”.
•
Adjust the re-start time.
•
The pump starts & stops on the mini-
•
mum level probe (2 probes mode).
Maximum and minimum level probes inverted.
•
Place the probes in the correct position.
•
Level control doesn’t work correctly.
•
Incorrect ground connection.
•
Damaged wires.
•
Check the ground connection.
•
Check the integrity of the wires.
•
The pump doesn’t start, low level light
•
is off, External ON/OFF is not being
used.
External ON/OFF is open circuit.
•
Place a jumper over the External ON/OFF terminal
•
blocks.
The pump doesn’t start, low level light
•
is off, External ON/OFF is not being
used.
External ON/OFF is open or no supply voltage
•
is applied.
Check the external remote control.
•
The circuit breaker trips on start-up.
•
Excessive current consumption.
•
Verify the pump and its wiring.
•
The pump doesn’t stop with External
•
ON/OFF or level control.
“MANUAL” mode selected.
•
Select the “AUTO” mode.
