The operate signals from the protections and an external trip are connected to the two
trip output contacts PO3 (X100:15-19) and PO4 (X100:20-24) 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 autoreclosing
DARREC1_OPEN_CB are connected directly to the output contact PO3
(X100:15-19).
TRPPTRC1 and 2 provide the lockout/latching function, event generation and the trip
signal duration setting. One binary input through SELGAPC1 can be connected to the
RST_LKOUT input of the Master Trip. If the lockout operation mode is selected, it is
used to enable external reset.

Figure 115: Circuit breaker control
The ENA_CLOSE input, which enables the closing of the circuit breaker, is
interlocked by two master trip signals. Any one trip will block the breaker from
closing. An always true signal is also connected to ENA_CLOSE via SELGAPC1 by
default. The open operation is always enabled.
