ALARM MESSAGES

In the case of anomalies or if the set safety limits are exceeded, the red alarm light switches on and the alarm in progress is
visualised on the display.
1) Control of the direction of rotation
It is activated in the case of incorrect phase sequence. The alarm blocks the compressor. To
re-activate functioning the phases must be first restored.
N.B To reset the alarm completely the electric power supply must be removed
2) Control temperature probe
It is activated if the temperature probe breaks (probe open or in short circuit). The alarm
blocks the compressor. To restore functioning check the connection and/or replace the probe
.
and press the key
3) Maximum oil temperature
It is activated when the maximum oil temperature is reached. The alarm blocks the compressor.
To re-start wait for the temperature to fall below the programmed value and act on the button
4) Minimum oil temperature
It is activated when the minimum oil temperature is reached. The alarm blocks the compressor.
To re-start wait for the temperature to rise above the programmed value and act on the button
5) Oil temperature pre-alarm
It is activated when the oil pre-alarm value has been reached. The alarm does not block the
compressor. Act on the button
6) Motor circuit breaker
It is activated when the motor circuit breaker relay intervenes. The alarm blocks the compressor.
Act on the button to silence the alarm after the cause has been verified.
7) Emergency
It is activated when the emergency button is pressed which blocks the compressor. Act on the
button to silence the alarm after having restored the status of the emergency button.
8) Machine maintenance pre-alarm
This alarm informs the user that the machine requires routine maintenance (oil change, filters,
etc.). The alarm must be silenced by the operator that carries out the maintenance by selecting
"Pre-alarm times" from the menu and by restoring the value as described in the "Parameters that
can be modified" – chapter point (1).
9) Pressure separator switch
It is activated on opening of the pressure separator gauge contact. The alarm blocks the
compressor. To silence the alarm press the
pressure separator gauge.
10) Fault 4-20 mA (pressure sensor)
It is activated when the pressure sensor connected to the 4-20mA input does not function
correctly. The alarm blocks the compressor. To silence the alarm press the
having restored the normal status of the pressure sensor
11) Maximum pressure
It is activated when the maximum set pressure is exceeded. The alarm blocks the compressor. To
silence the alarm press the
12) Inverter faulty
Press the key to silence the alarm. If problem persists, contact a service center without
delay.
