Figure 45: Synchrocheck function
Two types of disconnector and earthing switch function blocks are available.
DCSXSWI1...3 and ESSXSWI1...2 are status only type and DCXSWI1...2 and
ESXSWI1 are controllable type. By default, the status only blocks are connected in a
standard configuration. The disconnector (CB truck) and line side earthing switch
status information is connected to DCSXSWI1 and ESSXSI1 respectively.

Figure 47: Earth switch control logic
The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The
input can be activated by the configuration logic, which is a combination of the
disconnector or breaker truck and the earth-switch position status and status of the trip
logics.
The OKPOS output from DCSXSWI defines whether the disconnector or breaker
truck is either open (in test position) or close (in service position). This output,
together with the open earth switch and non-active trip signals, activates the close-
enable signal to the circuit breaker control function block. The open operation for
circuit breaker is always enabled.
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.
