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.
