The operate signals from the protections described above are connected to both of
the two trip output contacts PO3 (X100:16-19) and PO4 (X100:20-23) via the
corresponding Master Trips TRPPTRC1 and TRPPTRC2. The open control
commands to the circuit breaker from local or remote CBXCBR1-exe_op or from the
auto-recloser DARREC1-open_cb are connected directly to the output PO3
(X100:16-19).
The TRPPTRC1 and 2 blocks provide the lockout/latching function, event generation
and the trip signal duration setting. In case the lockout operation mode is selected,
the binary input 4 (X120:5-6) is assigned to the RST_LKOUT input of the Master
Trip to enable external reset with a push button.
