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.•
