Figure 39: Circuit breaker control
There are three disconnector status blocks (DCSXSWI1...3) available in the IED.
The remaining two not described in the functional diagram are available in SMT for
connection where applicable.
The binary inputs 5 and 6 of the additional card X110 are used for busbar disconnector
(DCSXSWI1) or circuit breaker truck position indication.
Primary device position
Busbar disconnector closed
Busbar disconnector open
CB truck in service position
CB truck in test position
The binary inputs 7 and 8 (X110:11-13) are for the position indication of the line side
earthing switch.
The circuit breaker closing is enabled when the ENA_CLOSE input is activated. This
can be done by the configuration logic, which is a combination of the disconnector
or breaker truck and earthing switch position statuses and the statuses of the master
Input to be energized
Input 5 (X110:8-9) Input 6 (X110:10-9)
