TRPPTRC1 and TRPPTRC2 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.

The ENA_CLOSE input, which enables the closing of the circuit breaker, is
interlocked by two master trip signals. Any trip blocks the breaker from closing. An
always true signal is also connected to ENA_CLOSE via SELGAPC1 by default. The
open operation is always enabled.
