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 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!
