the controller performs the following functions:
-
Control the compressor and dryer (for versions with dryer)
-
Protect the compressor and dryer (for versions with dryer)
-

Automatic restart after network voltage failure (optional mode).
Automatic control of compressor
The controller keeps the output pressure within programmed limits, controlling the loading and unloading compressor modes. Various set
parameters are taken into account, including: unloading and loading pressure, minimum stop time and maximum number of motor starts.
Protection of compressor
Fail stop
If the temperature at the element outlet exceeds the set fail stop value, the compressor is stopped. This is indicated on the display (3). The
compressor also stops in the event of an inverter alarm.
See the safety instructions before taking any action.
Alarm:
An alarm limit can be set below the fail stop limit value.
If any of the values measured exceed the alarm limit value, this will be indicated before reaching the fail stop limit value.
Service warning:
If the service timer exceeds the set value, this will be indicated on the display (3) to inform the operator.
