4.1 Controller and operating panel

The compressors A7.5 to A22 are equipped with an t-Log electronic controller. The t-Log 

electronic controller maintains the net pressure between programmable limits by automa-
tically loading and unloading the compressor. A number of programmable settings, e.g. the 
unloading and loading pressures, the minimum stop time and the maximum number of 
motor starts are taken into account. The t-Log electronic controller stops the compressor 
whenever possible to reduce the power consumption and restarts it automatically when the 
net pressure decreases. In case the expected unloading period is too short, the compressor 
is kept running to prevent too short standstill periods.
