If both of the circuit breaker contacts 52a and 52b are available, they should be wired to the two
physical inputs. These physical inputs are then assigned to the corresponding logical inputs: the
circuit breaker 52a contact to the "52a Input" logical input, and the circuit breaker 52b contact to
the "52b Input" logical input. The circuit breaker's automaton is considered as having eight
statuses: Start, open, closed, error, opening time, opening fault, closing time and closing fault.
The circuit breaker performance is shown in the following finite state machine:
4.7.1. Circuit Breaker opening and closing commands
The circuit breaker opening and closing commands are implemented. These commands can be
executed from the HMI commands menu or using the HMI’s specific keypad or from local or
remote communications. In order that the command related to the key can run, the menu must
be in standby mode.
To carry out commands from the remote communications (ModBus, IEC60870-5-103, IEC61850
or DNP 3.0) the equipment must be in TELECONTROL mode. (see the telecontrol section).
For the commands to have an effect, they should be assigned to the corresponding outputs. The
"Open circuit breaker" and "Close circuit breaker" bits are assigned to their corresponding
outputs in the "CONTROL" status group in the status menu.
4.7.2. Counter to register the number of openings
The SIL-D equipment is fitted with a counter that registers the number of times the circuit breaker
opens.
This counter is associated with the "Maximum number of openings" setting. When the number of
openings exceeds this preset value, the "Maximum number of openings" status is activated and
its corresponding event is generated.
This counter reading can be set to any value from within its range from the HMI or by
communications.
