Terminology
Term Explanation
ARAVF Automatic Restart After Voltage Failure. See section General.
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 your supplier.
Restart delay This parameter allows to programme that not all compressors are restarted at the same
time after a power failure (ARAVF active).
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 your supplier.
Minimum stop
time
Once the compressor has automatically stopped, it will remain stopped for the minimum
stop time, whatever happens with the net air pressure. Consult your supplier if a setting
lower than 20 seconds is required.
Starting /
stopping
pressure
The regulator does not accept inconsistent settings, e.g. if the stopping pressure is
programmed at 7.0 bar(e) (101 psi(g)), the maximum limit for the starting pressure
changes to 6.9 bar(e) (100 psi(g)). The recommended minimum pressure difference
between starting and stopping is 0.6 bar (9 psi(g)).
