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 25: 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.
