If the unit is blocked, the energy supply to the drive motor must be immediately dis-
connected.
The cause of malfunction must be determined.
Aerzener Service can be quickly at hand and provide expert troubleshooting for you.
The unit must not be taken into operation until it is properly functioning.
Information on operating/protecting
the compressor stage and the pressurised pipeline elements
The compressor stage is protected by oil pressure, discharge temperature and
•
discharge pressure sensors. The sensors are connected to a fault signalling de-
vice/control at the factory. If the permissible operating parameters are exceeded
or undershot, the fault signalling device/control switches the drive motor off. In the
case of systems without a fault signalling device/control, the customer must install
an appropriate fail-safe control.
To ensure proper operation, the fault signalling device/control must be incorpora-
•
ted into the drive motor safety chain in accordance with the circuit diagram. Plea-
se note
that the fault signalling device/control and drive motor are fed from the
same
circuit, so that the motor cannot be operated without compressor protection.
