Problem
Cause
Solution
The system doesn’t work
•
and the power-on pilot light
is off while main power
supply voltage is present.
Blown control fuse.
•
Wrong input connection
•
Phase failure.
•
Supply over-voltage.
•
Replace with appropiate fuse.
•
Connect accurately.
•
Check phases.
•
Verify voltage.
•
The system is working but
•
the contactor does not
activated.
Voltage selection error.
•
Verify voltage selection.
•
Pump alarm trips.
•
Low overcurrent adjustment.
•
Input phase failure.
•
Anormal excessive motor
•
consumption.
Low current consumption <0,5 A.
•
Klixon input not use.
•
Check motor consumption and adjust
•
the current.
Check three supply phases.
•
Verify pump. The pump motor is
•
overloaded.
Check pump.
•
Short-circuit the non used Klixon
•
inputs.
Display shows “Err-SEn”
•
message.
The transducer isn’t connected
•
Transducer current is <2 mA.
•
Connect the 4-20 mA transducer.
•
Check transducer.
