1)Once the compressor module is automatically stopped, it will remain stopped for the minimum stop time, whatever happens with the air net pressure.

2)The regulator does not accept illogical settings, e.g. if the stopping pressure is programmed at 7.0 bar(e), the maximum limit for the starting pressure changes into 6.9 bar(e). The recommended minimum pressure difference between starting and stopping is 0.6 bar.

3)Is only accessible if the automatic restart function is activated. The power recovery time (the period within which the voltage must be restored to have an automatic restart) can be set between 10 and 3600 seconds. A delay at restarting can also be programmed, allowing e.g. compressors to be restarted one after the other. To activate the automatic restart function, consult Atlas Copco.

4)Full-Feature version is the Pack version with integrated air dryer.

5)Is the time period during which the warning signal must exist before the warning message appears.

6)Is the time period during which the warning signal is ignored after starting to allow the dryer to reach the dewpoint temperature.
