Several sensors are provided on the compressor. If one of these measurements exceeds the programmed shut-
down level, the compressor will be stopped. This will be indicated on display (1) and general alarm LED (2)
will blink.
Remedy the trouble and reset the message. See also the Inputs menu.
Before remedying, consult the applicable safety precautions.
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
If one of the measurements exceeds the programmed shut-down warning level, a message will appear on
display (1) and general alarm LED (2) will light up, to warn the operator that the shut-down warning level is
exceeded.
The message disappears as soon as the warning condition disappears.
Service warning
A number of service operations are grouped (called Service Plans). Each Service Plan has a programmed time
interval. If a time interval is exceeded, a message will appear on display (1) to warn the operator to carry out
the service actions belonging to that Service Plan.
Automatic restart after voltage failure
The regulator has a built-in function to automatically restart the compressor if the voltage is restored after
voltage failure. This function is activated. If desired, the function can be deactivated. Consult Atlas Copco.
If activated and provided the regulator was in the automatic operation mode, the
compressor will automatically restart if the supply voltage to the module is restored!
