ALARM MESSAGES
When a fault occurs or the safety limits set are exceeded, the red alarm light comes on and the alarm in progress is shown on
the display.
In the case of multiple alarms, use
to scroll through the items.
To silence an alarm, press the RESET button.
To delete all the non-active alarms, press RESET and hold it down for at least 2 seconds.
•
rot.dir.error
Alarm tripped in the event of an incorrect phase sequence. The alarm blocks compressor operation; to restart operation, the
correct phase sequence must be re-established.
N.B.: To completely reset the alarm you have to switch off the electrical power supply.
•
air.temp.sens. fault
Alarm tripped in the event of a temperature sensor fault (sensor open or short circuit). The alarm blocks compressor operation;
to restore operation, check the connection and/or replace the sensor, then press the RESET button XX.
•
screw.temp.sens. fault
Alarm tripped in the event of a temperature sensor fault (sensor open or short circuit). The alarm blocks compressor operation;
to restore operation, check the connection and/or replace the sensor, then press the RESET button XX.
•
max.oil.temp.
Alarm tripped when the maximum oil temperature is reached. The alarm blocks compressor operation; to restore operation,
wait for the temperature to fall below the programmed value, then press the RESET button XX.
•
min.oil.temp.
Alarm tripped when the minimum oil temperature is reached. The alarm blocks compressor operation; to restore operation, wait
for the temperature to rises above the programmed value, then press the RESET button XX.
•
oil.temp.pre-alarm
Alarm tripped when the pre-alarm oil temperature is reached. The alarm does not block compressor operation. To silence the
alarm, press the RESET button XX.
•
Motor thermal overload
Alarm tripped when the motor PTC thermal relay + fan motor thermal relay is tripped. The alarm blocks compressor operation.
To silence the alarm, first verify the cause and then press the RESET button XX.
•
Emergency button
Alarm tripped when the emergency button is pressed, which blocks compressor operation. To silence the alarm, first reset the
emergency button, then press the RESET button XX.
•
Maintenance
This alarm signals the user that the machine is due for routine maintenance (oil change, filters, etc.).
The alarm must be silenced by the service technician who performs the maintenance, as described in the section “Modifiable
Parameters”.
•
max.press.alarm
Alarm tripped when the maximum pressure set is exceeded. The alarm blocks compressor operation.
To silence the alarm, first restore the correct pressure, then press the RESET button XX.
•
press.sens.fault
Alarm tripped when the pressure sensor connected to the 4-20mA input is not working correctly. The alarm blocks compressor
operation.
To silence the alarm, first restore the normal status of the pressure sensor, then press the RESET button XX.
•
comm.error
Alarm tripped when communication between the control unit and the display is interrupted. The alarm blocks compressor
operation.
Check the connections and press RESET XX.
•
screw.motor.therm. (only if parameter 23 is activated)
Alarm tripped in the event that the screw motor thermal relay is tripped. The alarm blocks compressor operation.
To silence the alarm, first verify the cause, then press the RESET button XX.
•
fan.motor.therm. (only if parameter 23 is activated)
Alarm tripped in the event that the fan motor thermal relay is tripped. The alarm blocks compressor operation.
To silence the alarm, first verify the cause, then press the RESET button XX.
•
Max starts/hour
indicates the number of starts per hour is greater that that imposed. The alarm does not block the compressor, but persists for
an hour, after which it resets itself automatically.
If this alarm activates itself frequently, check and if necessary increase the empty cycle time.
•
Err. remote pressure
this activates itself in case of anomalies of the external pressure switch. The alarm does not block the compressor, but persists
until the resetting of the correct control sequence
•
Inverter error
Alarm tripped only when the inverter is present.
