Liquiline Control CDC90

Endress+Hauser

5

The IPC is responsible for retracting the assembly and activating the pilot valve manifold, and

processes all the states of the float switches and pressure switches.

The IPC only establishes digital fieldbus communication to the control station.

In both the IPC and the Liquiline transmitter, operation and configuration is possible via the device's

web server.

Primary operation is via the IPC. As the Liquiline transmitter is preconfigured upon delivery, it

generally does not require any further configuration.

The assignment of the inputs and outputs is provided in the following table and graphic:
