The displays on the control module do not switch on.
- Power line failure or the emergency switch or the thermal magnetic switch is open.
Bad contact at a connector or socket in the high-voltage power line.
- Check and fix.
Thermal magnetic cutout tripped
- Look for a short-circuit in the electrical system or the motors.
- Check the available supply kW against the power requirements kW. Reduce speed if
low power is found to be the cause.
Bad contact in the power cable or the board of the stopped module or the module
before it.
- Replace the defective cable or board,; check fuses (see electrical diagram).
Adjustable frequency drive has cut out due to overtemperature.
- Drive temperature sensor is faulty; once a given temperature threshold is reached
it is not starting the cooling fan, or the fan is faulty or jammed by dirt (in all cases,
call the after-sales service). To restart: switch off the machine with the emergency
switch and blow compressed air on the drive to remove any felt which is blocking
the slits and jamming the fan.
Inverter in blocco per sovraccarico do potenza.
- Verificare se funziona diminuendo la velocità o eliminando una testa. Cercare poi
il difetto in qualche parte meccanica non scorrevole che potrebbe determinare
il sovraccarico. In ogni caso consultare l'Assistenza Tecnica per la riparazione o la
sostituzione del particolare difettoso (vedi schema).
Inverter stopped due to overload 2 fig.11.
� Reduce the speed or eliminate one of the heads, then check if the inverter resumes
operation. Then check that all mechanical parts move freely. In any case, consult the
Service Centre regarding repair or replacement of the defective part (refer to diagram).
One of the sensors is short-circuited.
- Disconnect each of these sensors in turn to identify the one at fault, then replace.
The machine's autodiagnosis function detects a number of heads different from the
number actually installed.
- Check the serial communication cable.
- Check the relay boards.
Motor (4 Fig. 7) stopped.
- If the motor overheats, a cutout is tripped; identify the cause of overheating; clean
the motor and check that the roller turns freely.
Motor power supply failure
- Check the motor connector on the board inside the cover (1 Fig. 12) and check for
loose connections
