Example: If the compressor element outlet temperature exceeds the programmed shutdown
level, the compressor will be stopped. This will be indicated on the display of the controller.
The compressor will also be stopped in case of overload of the drive motor.
Air-cooled compressors will also be stopped in the event of overload of the fan motor.
Before remedying, consult the
Shutdown warning
A shutdown warning level is a programmable level below the shutdown level.
If one of the measurements exceeds the programmed shutdown warning level, this will also be
indicated to warn the operator before the shutdown level is reached.
The message disappears as soon as the warning condition disappears.
A warning will also appear if the dew point temperature is too high (on compressors with
integrated dryer).
Service warning
A number of service operations are grouped (called Service Plans). Each Service Plan has a
programmed time interval. If the service timer exceeds a programmed value, this will be indicated
on the display to warn the operator to carry out the service actions belonging to that Service Plan.
Automatic restart after voltage failure
The controller has a built-in function to automatically restart the compressor when the voltage is
restored after voltage failure. For compressors leaving the factory, this function is made inactive.
If desired, the function can be activated. Consult your local supplier.
If the function is activated and provided the regulator was in the automatic operation
mode, the compressor will automatically restart if the supply voltage to the module is
restored.
The ARAVF label (see section Pictographs) shall be glued near to the controller.
