Functional diagrams for control and interlocking

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
standard configuration. The disconnector (CB truck) and line side earthing switch
status information is connected to DCSXSWI1 and ESSXSI1.

Figure 254: 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 earth-switch position status, status of the trip logics,
gas pressure alarm and the circuit breaker spring charging status.
The OKPOS output from DCSXSWI defines if the disconnector or breaker truck is
definitely 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.
SYNC_ITL_BYP overrides, for example, active interlocking conditions when the
circuit breaker truck is closed in service position.
Connect the additional signals required for the application for closing
and opening of circuit breaker.
