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.
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.
Other warnings
On compressors equipped with an integrated dryer, a warning message will appear if the dew point is too
high or too low for the given ambient temperature.
Automatic restart after voltage failure
The regulator has a built-in function to automatically restart the compressor when the voltage is restored
after voltage failure. This function is deactivated in compressors leaving the factory. If desired, the function
can be activated. Consult the Atlas Copco Customer Centre.
If activated, and if the regulator was in the automatic operation mode, the compressor
will automatically restart when the supply voltage to the module is restored!
