Functional diagrams for control and interlocking

The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The input
can be activated using the configuration logic, which is based on the status of the trip
logics. However, other signals can be connected based on the application needs.
The SYNC_ITL_BYP input can be used, for example, to always enable the closing of the
circuit breaker when the circuit breaker truck is in the test position. SYNC_ITL_BYP
overrides, for example, active interlocking conditions when the circuit breaker truck is
closed in service position.
