Description

Automatic operation

After reaching the switch-

Load/idle operation

The compressor switches between
"Load" and "Idle" operation; i.e. there
is an unlimited run-on.

Lead lag control mode
(LLC operation)

The switch on/off pressure set is not
taken into account by the controller.
The compressor is controlled by a
master controller.

The safety pressure is the sum of the set maximum pr

compressor is switched off with a fault message. If the maximum
pressure is exceeded by 7 PSI, a warning appears on the display.
