Service warning
A number of service operations are grouped (called Level A, B, C, ...). Each level has a programmed time
interval. If a time interval is exceeded, a message will appear on display (1) to warn the operator to carry out
the service actions belonging to that level.
Automatic restart after voltage failure
The regulator has a built-in function to automatically restart the compressor if the voltage is restored after
voltage failure. This function is deactivated in compressors leaving the factory. If desired, the function can
be activated. Consult Atlas Copco.
If activated and provided the module was in the automatic operation mode, the compressor
will automatically restart if the supply voltage to the module is restored within a
programmed time period.
The power recovery time (the period within which the voltage must be restored to have an
automatic restart) can be set between 15 and 3600 seconds or to Infinite. If the power
recovery time is set to Infinite, the compressor will always restart after a voltage failure,
no matter how long it takes to restore the voltage. A restart delay can also be programmed,
allowing e.g. two compressors to be restarted one after the other.
