Explanation
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.
This parameter allows to programme that not all compressors are restarted at the same
time after a power failure (ARAVF active).
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).
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.
Once the compressor has automatically stopped, it will remain stopped for the minimum
stop time, whatever happens with the net air pressure. Consult Atlas Copco if a setting
lower than 20 seconds is required.
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)).
