CHAPTER 5: SETTINGS SYSTEM SETUPM60 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 5-1495The breaker control element contains the auxiliary logic for status and serves as the interface for opening and closing of acircuit breaker from protection, autoreclose, SCADA, or through the front panel interface. The breaker control element canbe used to create interlocking functionality. For greater security in determination of the breaker position, both the 52/a and52/b auxiliary contacts are used with reporting of the discrepancy between them.To use this element, configure the contact outputs that trip and close the breaker to use FlexLogic operands BREAKER 1 OFFCMD (or BREAKER 1 TRIP A/B/C in the case of single-pole tripping) and BREAKER 1 ON CMD, and configure the breaker controlelement inputs as described here.A description of the operation of the breaker control and status monitoring features from the front panel is provided inchapter 4.There are two breaker control elements for each CT/VT module installed. The following settings are available for eachbreaker control element.BREAKER 1 FUNCTION — This setting enables and disables the operation of the breaker 1 control feature.BREAKER1 PUSH BUTTON CONTROL — Set to “Enable” to allow front panel pushbutton open/close control operations.BREAKER1 TAGGING — Set to "Enable" to allow the graphical front panel to tag breaker 1. When tagged, the followingoperations are disabled: pushbutton open/close, IEC 61850 open/close, and close command initiated by BREAKER 1 CLOSEsetting. The trip command issued by the Trip Out element or BREAKER 1 OPEN setting is not affected.BREAKER1 SUBSTITUTN — Set to "Enable" to allow the graphical front panel to substitute breaker 1 status. When substituted,breaker 1 control open/close status is forced to the substituted value.BREAKER1 BYPASS — Set to "Enable" to allow the graphical front panel to bypass breaker 1 interlocking. When asserted,BREAKER 1 BLK OPEN and BREAKER 1 BLK CLOSE settings are bypassed.BREAKER 1 NAME — Assign a user-defined name (up to six characters) to the breaker. This name is used in flash messagesrelated to breaker 1.BREAKER 1 MODE — Selects “3-Pole” mode, where all breaker poles are operated simultaneously, or “1-Pole” mode where allbreaker poles are operated either independently or simultaneously.
