Example: If the compressor element outlet temperature exceeds the programmed shut-down 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 Safety precautions.
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
If one of the measurements exceeds the programmed shut-down warning level, this will also be indicated to
warn the operator before the shut-down level is reached.
Service warning
If the service timer exceeds a programmed value, this will be indicated on the display to warn the operator
to carry out some service actions.
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. The ARAVF label 1079 9932 74( see
section Pictographs ) shall be glued near to
the controller. 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.
