ARAVF
Activating automatic restart after voltage failure
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 program that not all compressors are restarted at the same time after a power
failure (ARAVF active).
Compressor element outlet
The regulator does not accept inconsistent settings, e.g. if the warning level is programmed at 95 ˚C
(203 ˚F), the minimum limit for the shut-down level changes to 96 ˚C (204 ˚F). The recommended
difference between the warning level and shut-down level is 10 ˚C (18 ˚F).
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.
Unloading/ Loading pressure The regulator does not accept illogical settings, e.g. if the unloading pressure is programmed at 7.0 bar(e)
(101 psi(g)), the maximum limit for the loading pressure changes to 6.9 bar(e) (100 psi(g)). The
recommended minimum pressure difference between loading and unloading is 0.6 bar (9 psi(g)).
