Problem
Cause
Resolution
High pressure safety
has tripped causing
the machine to stop.
The pressure exceeds the
alarm set point.
Transducer does not detect
pressure properly.
Check line pressure, vent pressure and
return to operating set point.
Low temperature
safety has tripped
causing machine to
stop.
Environmental temperature
below the electronic
controller setting.
In this phase, if the start button is pressed
intermittently, the machine starts in STAR
mode and the temperature should return to
above the setting. As soon as it does, the
machine will start running again in automatic
mode.
Check the environmental temperature and, if
necessary, use a heating resistance on the
oil circuit. Contact an Authorized Service
Centre.
Compressor runs
but does not
charge.
Suction valve does not
open.
Auxiliary power
disconnected, solenoid
valve fuses blown.
Make certain that the transducer is connected
both electrically and pneumatically.
Check that the solenoid valve installed on the
suction regulator is functioning properly.
Possible check valve or minimum pressure
valve failure. Contact an Authorized Service
Centre.
Check the fuses for the solenoid valve
installed on the terminal inside the starter
itself.
When starting up the
unit for the first time,
the machine does not
start. Phase anomaly
alarm.

correct.
Invert two power supply phases on the main
switch.
WARNING!!! UNPLUG THE MACHINE.
Oil leaking from air
filter.
Oil level is too high.
Suction valve defective.
Drain the oil until the correct level is
reached. For the valve, contact an
Authorized Service Centre.

safety valve vented.
During no-load operation
the machine is not
depressurized.

clogged.
Contact an Authorized Service Centre.
Excessive oil
consumption.
Oil not suitable for the
compressor operation.
Air-oil separator cartridge
spent or defective.
