3.8.3.3 Functional diagrams for control and interlocking
The operate signals from the protections are connected to the two trip output contacts
PO3 (X100:16-19) and PO4 (X100:20-23) via the corresponding Master Trips
TRPPTRC1 and TRPPTRC2. 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 TRPPTRC2 blocks provide the lockout/latching function, event
generation and trip signal duration setting. If the lockout operation mode is selected,
one binary input can be re-assigned to the RST_LKOUT input of the Master Trip to
enable external reset with a push button.
