ECPSCH (85)
Main menu/Test/Function status/Scheme communication/
EFSchemeCommunication(PSCH,85)/EFC
Displays available instances of ECPSCH (85) with some measurements indicating
carrier and trip status.

Local acceleration logic ZCLCPLAL

Main Menu/Test/Function status/Scheme communication/
LocalAccelerationLogic(PLAL)/ZCLC
Displays available measurements indicating trip by loss of load or by zone extension

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 pickup and current data.

Fuse failure supervision SDDRFUF

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

Control

There are large amounts of output data from the control functions. The main categories
of data are found under Synchronism-check, Autorecloser 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.
