The disconnect switch 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 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
depends on the number of the CT/VT modules ordered with the D30.
SWITCH 1 FUNCTION
— Assign a user-defined name (up to six characters) to the disconnect switch. This name is used in flash

messages related to disconnect switch 1.
— This setting selects "3-Pole" mode, where disconnect switch poles have a single common auxiliary

switch, or "1-Pole" mode where each disconnect switch pole has its own auxiliary switch.
— This setting selects an operand that creates a programmable signal to operate a contact output to open
