Micom P634 - Blocked;Faulty; Starting Signals and Tripping Logic

3.12.12 Blocked/Faulty
If the protective functions are blocked, the condition is signaled by continuous
illumination of the amber LED indicator H 2 on the local control panel and by a
signal from an output relay configured MAIN: Blocked/faulty. In addition
functions can be selected that will issue the MAIN: Blocked/faulty signal by
setting a “m out of n” parameter.

3.12.13 Starting Signals and Tripping Logic
3.12.13.1 Tripping Signals for Autotransformers
The following tripping signals are available for applications with
autotransformers:
MAIN: Trip sig.REF1 & REF2 036 174
MAIN: Trip sig.REF2 & REF3 036 175
MAIN: Trip sig.REF1 & REF3 036 176
For signaling (e.g. via LED) an additional group signal (019 200) "MAIN: REFn
trip signal" is provided, which is formed by OR-combination of the trip signals
of all available REF protections.
3.12.13.2 Starting Signals
The trip signals of differential protection and ground differential protection plus
the general starting signals of the definite-time and inverse-time overcurrent
protection functions are combined into one common general starting signal.
