If the control unit registers a fault, the compressor is immediately and
– without any idling phase – automatically shut down. The error relay drops
and on the right, next to the actual pressure value, a number blinks next
to the red indicator lamp:
– the blinking number indicates the registered cause (see also section „Mes-
sage key table" on page 11).
Acknowledgement of messages
Display the message – e.g. by pressing the Info key

Faults
Rectification
Employ suitable measures to improve the air inlet and venti-
lation in the installation room
Clean cooling unit externally
Keep air inlet opening to the compressor clean;
check to ensure that any existing cooling air duct systems are
adequatly dimensioned
Top up oil
Replace temperature sensor or repair the wire break
Ensure correct voltage conditions:
Constant voltage in accordance with IEC 38
Improve motor cooling:
improve ventilation of the installation room;
clean the cooling unit
Clean motor cooling air supply
Exchange oil separator cartridge
Reduce net pressure to prevent compressor from building up
a pressure exceeding the permissible max. pressure
Overhaul motor
