Operation

4.1 Controller and operating panel

The compressors A75 to A90 are equipped with a pro-Log electronic controller.
The pro-Log electronic controller maintains the net pressure between programmable limits
by automatically loading and unloading the compressor. A number of programmable set-
tings, e.g. the unloading and loading pressures, the minimum stop time and the maximum
number of motor starts are taken into account.
The pro-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.
Operating panel
In order to control the compressor and to read and modify programmable parame-
ters the controller has a control panel provided with:
- LEDs indicating the status of the compressor;
- a display indicating the operating conditions, a service need or a fault;
- buttons to control the compressor and access data collected by the controller;
- buttons to manually start and stop the compressor;
- an emergency stop button (separate installed)
