TROUBLESHOOTING
- Check that the inverter has been correctly connected to the power line (which is on)
- Check that the motor pumps have been correctly connected to the inverter
- Check that all the cables and connections are operative.
PROBLEM
The pump is not feeded
Message
Cause
intervention
none
Interruption of power supply Replace the power supply
none
Intervention of the line protections Check the correct protecttions setting
INPUT ERROR
(only mod. T/T) - connections LINE and
MOTOR were reversed
Check the connections LINE and MOTOR and connect
correctly
PROBLEM The current circuit breaker has tripped to protect the DGBOX power line
Message
Cause
intervention
none
The residual current circuit breaker is
inadequate for inverter supply
Replace the residual current circuit breaker with a model
suitable for the pulsating components and in direct current
(class A)

OVER
CURRENT
overcurrent absorption compared to set
value (parameter A in BASE PARAMETER)
- check the correct current setting
- check the power voltage under load at pump terminals (min -
15%)
- make sure the motor pump is turning freely and is not braked
- check the correct direction of rotation
- check the correct sizing of the wires
CURRENT
LIMIT
Serious overcurrent absorption which
inverter cannot cope with
Make sure the motor pump is not bl
ocked, reduce the motor
acceleration by means of the ACCELERATION parameter.
DRY
RUNNING
(DRY
RUNNING PF)
- Lack of water at suction
- pump not primed
- suction blocked
-
wrong direction of motor rotation
- Check correct suction conditions
- prime the pump
- check the suction piping
-
check the correct d
irect
ion of motor rotation
LOW PRESS
The system does not reach the minimum
pressure
Check that there are no broken pipes.
LOW
VOLTAGE
Deviation of the supply voltage higher than
–
15% of the plate voltage
Check the supply voltage and the section and length of the
inverter power cables
HIGH
VOLTAGE
Deviation of the supply voltage higher than
+15% of the plate voltage
Check the supply voltage
OVER TEMP
MODULE
Module overheating due to overload check the pump load
COM ERROR
No communication between control board
and power board
Check the integrity of the connection cable and connections;
the power board coul
d be damaged
LOW LEVEL
No level signal with level signal input on Make sure there is water at suction or check level signal
