3.3 Functionality
The start and stop function can be set to manual or automatic
operation.
It is possible to combine these two into a semi-automatic operation.

From this status more information about all system configuration
settings can be got, or the engine can be started immediately by
pressing the Start button.
When the Start button is pressed, the CCM checks all sensor inputs
and parameters. The engine cranking procedure begins.
The engine starts, and the warmup procedure begins.
When the compressor is ready to be loaded, it goes into the Not
Loaded status.
The operator can now load the compressor at any time by pressing
the Load button.
When loaded, the compressor's regulating system becomes active.
Actual pressure and setpressure are displayed, as well as the
condition of the regulating system (load or unload).

begins. The engine stops and the compressor will automatically

regulating system immediately becomes active.

the stopping procedure begins. The engine stops and the
compressor returns to the Standby status, with the automatic start
already activated.
