2.4.2
Unblocking overreach protection (UOP)
DEFCAR sends a trip block signal in UOP. Thus, UOP stops to send a trip block signal for an
internal fault. Settings and operation of UOP is the same as POP.
2.4.3
Blocking overreach protection (BOP)
BOP send a trip block signal except for an internal fault. When DEFCF operates, BOP issues
a 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 the
trip block signal from the opposite terminal. Therefore, user should set a time depending on
the 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 used
to send/receive a trip blocking signal.
For setting [
TREBK-DEF
], see section 2.4.1.
