Figure 2.3-1 Operation decision in FS logic
Figure 2.3-2 illustrates that fail-safe signals are provided for CH1 etc. with the decisions of
UVFS etc. relays in the FS function and instructions of the replica procedure. Be aware that
failsafe signals generated for trip signals of other protection functions in respective 24 CHs;
