4.1 Controller and operating panel
The compressors A7.5 to A22 are equipped with an e-Log electronic controller.
The e-Log electronic controller maintains the net pressure between programmable limits by
automatically loading and unloading the compressor. A number of programmable settings,
e.g. the unloading and loading pressures, the minimum stop time and the maximum num-
ber of motor starts are taken into account.
