Troubleshooting
Problem Cause Solution
The equipment does not work •
and the voltage light is off
even when the system is con-
nected to a power source.
Control fuse is burned out.•
Excessive power voltage. •
Wrong input connection (Vigilec •
Mini).
Phase failure (Vigilec Mini).•
Replace the corresponding fuse.•
Measure and check the power voltage. •
Connect correctly.•
Check phases.•
The system is working but the •
contactor does not activated.
Voltage selection error (Vigilec •
mini).
Verify voltage selection.•
Pump alarm trips.• Overcurrent adjustment (Amp. •
max/Amp. min) too low or critical.
Motor not connected.•
Input phase failure (Vigilec mini).•
Abnormal excessive motor con-•
sumption.
Low motor consumption <0,5A.•
Check motor consumption and adjust •
again the intensity.
Connect the motor.•
Check the three supply phases.•
Check the motor. The motor is over-•
loaded.
Check pump (there is no water in the •
pump intake, the pipe is clogged, etc.).
Level control doesn’t work •
correctly.
High and low level probes are •
reversed.
Wrong ground connection.•
Cut wires (Probes/Remote).•
Place the probes in the correct position.•
Check the ground connection.•
Check the wires continuity.•
