CHAPTER 5: SETTINGS SYSTEM SETUPD60 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5-13555.5.5 Disconnect switchesSETTINGS SYSTEM SETUP SWITCHES SWITCH 1(16)The disconnect switch control element contains the auxiliary logic for status and serves as the interface for opening andclosing of disconnect switches from SCADA or through the front panel interface. The disconnect switch control elementcan be used to create interlocking functionality. For greater security in determination of the switch pole position, both the89/a and 89/b auxiliary contacts are used with reporting of the discrepancy between them. The number of availabledisconnect switches is four per breaker.To use this element, configure the contact outputs that open and close the disconnect switch to use FlexLogic operandsSWITCH 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 operation of the disconnect switch element.SWITCH 1 NAME — Assign a user-defined name (up to six characters) to the disconnect switch. This name is used in flashmessages related to disconnect switch 1.SWITCH 1 MODE — This setting selects “3-Pole” mode, where disconnect switch poles have a single common auxiliaryswitch, or “1-Pole” mode where each disconnect switch pole has its own auxiliary switch.SWITCH 1 OPEN — This setting selects an operand that when activated, and unless blocked, initiates the disconnect switch 1open command.
