Scheme communication logic for residual overcurrent protection
ECPSCH
Main menu/Test/Function status/Scheme communication/
EFSchemeCommunication(PSCH,85)/ECPSCH:x
Displays available instances of ECPSCH with some measurements indicating
carrier and trip status.

Secondary system supervision

Values for Current circuit supervision and Fuse failure supervision are found under
Secondary circuit supervision. Fail and alarm detection information is available
together with various start and current data.

Current circuit supervision CCSRDIF

Main menu/Test/Function status/Secondary system supervision/
CurrentCircuitSupervision(RDIF,87)/CCSRDIF:x
Displays available instances of CCSRDIF with a number of measurements per
instance indicating the detection of current circuit failure and alarm operation.

Fuse failure supervision SDDRFUF

Main menu/Test/Function status/Secondary system supervision/
FuseFailure(RFUF)/SDDRFUF:x
Displays available instances of SDDRFUF with some measurements per instance
indicating start status.

Control

There are large amounts of output data from the control functions. The main
categories of data are found under Synchrocheck, and Apparatus control.
Apparatus control has by far the largest amount of data since this includes all the
interlocking information for several different breaker arrangements.
