Thus, UOP stops to send a trip block signal for aninternal fault. Settings and operation of UOP is the same as POP.2.3.3 Blocking overreach protection (BOP)BOP send a trip block signal except for an internal fault. When DEFCF operates, BOP issuesa trip single unless a trip-blocking single is received.The delayed pick-up timer [TCHD-DEF] is provided to allow for the transmission delay of thetrip block signal from the opposite terminal. Therefore, user should set a time depending onthe delay of communication channel.Setting [TCHD-DEF] = maximum signal transmission delay time†+ 5ms†Note: Including operation time of circuits of Binary IO modules, these circuits are usedto send/receive a trip-blocking signal.For setting [TREBK-DEF], see Chapter 2.3.1.
