Alarm! Air filter

:  

When an air filter anomaly occurs, the alarm BLOCKS the compressor.

Alarm! Oil separator filter

: When an oil separator filter anomaly occurs, the alarm BLOCKS the compressor.

Alarm! Inverter fault

:   

When an inverter anomaly occurs, the alarm BLOCKS the compressor. To re-start the 

compressor, you need to reset the inverter.

(

NOTE

: there is an alarm only if the inverter is enabled)

Warning! Remote press. alarm

: When the remote command and the loaded/no load pressures set on the control unit 

are inconsistent, the alarm DOES NOT BLOCK the compressor. The compressor continues to work 

with the pressures programmed on the control unit. The alarm stops only when the remote command 

starts working correctly again.

(

NOTE

: there is an alarm only if remote is enabled)

Warning! High dew point

: The dryer temperature remains over the total of the temperatures defined in the parameters 

“Temperature OFF” and “Temperature differential” for the time defined in the parameter “Alarms delay”.

(

NOTE

: there is an alarm only if the dryer is enabled)

Warning! Ice alarm

:  The dryer temperature remains under the temperature defined in the parameter “Temperature OFF” 

for the time defined in the parameter “Alarms delay”

(

NOTE

: there is an alarm only if the dryer is enabled)

Alarm! Dryer sen. faul

t:  When an anomaly occurs on the dryer temperature sensor (sensor short-circuited or open), if 

the parameter “Alarm type” is set as the “alarm”(see Dryer menu paragraph), the alarm BLOCKS the 

compressor, otherwise the compressor continues to work. To re-start the compressor, you need to 

replace the probe.

(

NOTE

: there is an alarm only if the dryer is enabled).
