The disconnect switch control element contains the auxiliary logic for status and serves as the interface for opening and
closing of disconnect switches from SCADA or through the front panel interface. The disconnect switch control element
can be used to create interlocking functionality. For greater security in determination of the switch pole position, both the
89/a and 89/b auxiliary contacts are used with reporting of the discrepancy between them. The number of available
disconnect switches is four per breaker.
To use this element, configure the contact outputs that open and close the disconnect switch to use FlexLogic operands
and
