Remark
A number of service operations are grouped (Level A, Level B, ...). Each level stands for a number of service
operations to be carried out at the programmed intervals. Consult your Atlas Copco Service Centre.

Explanation
ARAVF
Automatic restart after voltage failure.
See Elektronikon regulator.
Required stop
period/Minimum
stop time
Once the compressor has automatically stopped, it will remain stopped for the minimum
stop time (approx. 20 seconds), whatever the net air pressure. In automatic operation, the
compressor will not be stopped by the regulator until a standstill period of at least the sum
of the minimum stop time and required stop period is expected. However, if the decrease
in net air pressure should require a new start of the compressor, the regulator will start the
compressor after the minimum stop time.
Power recovery
time
Is the period within which the voltage must be restored to have an automatic restart. Is
accessible if the automatic restart is activated. To activate the automatic restart function,
consult Atlas Copco.
Delay at shut-
down signal
Is the time for which the signal must exist before the compressor is shut down. If it is
required to program this setting to another value, consult Atlas Copco.
