Explanation
Automatic restart after voltage failure.
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.
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.
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.
