Press 

-key 

 and the segment display shows the

compressor system pressure (pressure gauge 22).

Compressor

Press 

-key a second time 

 and the segment

display shows the total operating time in hours
together with the total running time symbol: 

.

Total operating time

Operating times,
output cycles,
maintenance dead-
lines, display test
and Software-No.

means: 124h total running time

Press 

O 

 Compressor Off 

 and the pressure

control function is deactivated and the display
shows the 

idling symbol. During this time the green

indicator blinks.

 The symbol O then appears and

the green indicator lamp is extinguished.

Switch off the
compressor

If the control unit detects a fault, the compressor is
switched off immediately and automatically – with-
out an idling phase –, the 

fault relay drops and

a digit on the right of the current pressure blinks
together with the red indicator lamp.

The blinking digit indicates the detected fault
(see also message key table page 1.12).
