PATH: SETTINGS  SYSTEM SETUP  SWITCHES  SWITCH 1(8)
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
SWITCH 1 OFF CMD and SWITCH 1 ON CMD, and configure the disconnect switch control element's inputs as outlined here.
• SWITCH 1 FUNCTION: This setting enables and disables the operation of the disconnect switch element.
• SWITCH 1 NAME: Assign a user-defined name (up to six characters) to the disconnect switch. This name will be used
in flash messages related to disconnect switch 1.
