Line 1 indicates the automatic or manual operation status of
the regulator:
Auto operation means that the regulator automatically
adapts the operation of the compressor, i.e. loading,
unloading, stopping and automatic restarting according to
the programmed parameters.
Man operation means that the automatic pressure control
function of the regulator is interrupted after pressing the
Unload key on the Main screen.
Line 2 indicates whether the regulator operates in local control
or remote control mode:
Local control means that the start/stop and load/unload
buttons on the keyboard are activated.
Remote control means that these functions are controlled
remotely. Consult Atlas Copco.
Line 3 indicates whether the timer which generates time-based
start and stop commands is activated or not. See section 13.
See section 2.3 for the functions of the keys Main, Help
and Xtra.
