activated for closing the circuit breaker or allowing the closing. The
SECRSYN1_SYNC_OK
output signal of SECRSYN is connected to
SYNC_OK
input
of CBXCBR through control logic. The function is blocked in case of terminal side or
bus side MCB is open.

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.

Earth switch control logic
The circuit breaker closing is disabled by default, as in case of generator, the closing
of the circuit breaker is done by a special synchronizer device.
The
OKPOS
output from DCSXSWI defines whether the disconnector or breaker
truck is open (in test position) or closed (in service position). This output, together
with the open earth switch and non-active trip signals, activates the signal enabling
closing to the circuit breaker control function block. The open operation for circuit
breaker is always enabled.
