The regulator has a built-in function to automatically restart the compressor if 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 the Atlas Copco Customer Centre.
If 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
