GE Multilin C60 Breaker Protection System 5-855 SETTINGS 5.2 PRODUCT SETUP5The digital state can be entered locally (by directly pressing the front panel pushbutton) or remotely (via FlexLogicoperands) into FlexLogic equations, protection elements, and control elements. Typical applications includebreaker control, autorecloser blocking, and setting groups changes. The user-programmable pushbuttons areunder the control level of password protection.The figure shows user-configurable pushbuttons for the enhanced front panel.Figure 5–14: USER-PROGRAMMABLE PUSHBUTTONS (ENHANCED FRONT PANELThe following figure shows user-configurable pushbuttons for the standard front panel.Figure 5–15: USER-PROGRAMMABLE PUSHBUTTONS (STANDARD FRONT PANEL)Both the standard and enhanced front panel pushbuttons can be custom labeled with a factory-provided template, availableonline at http://www.gegridsolutions.com/multilin. The EnerVista software can also be used to create labels for theenhanced front panel.Each pushbutton asserts its own “On” and “Off” FlexLogic operands (for example, PUSHBUTTON 1 ON and PUSHBUTTON 1OFF). These operands are available for each pushbutton and are used to program specific actions. If any pushbutton isactive, the ANY PB ON operand is asserted.Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the correspond-ing pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic operand through the PUSHBTN 1LED CTL setting.The activation and deactivation of user-programmable pushbuttons depends on whether latched or self-reset mode is pro-grammed.• Latched mode: In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the PUSH-BTN 1 SET setting or by directly pressing the associated front panel pushbutton. The state of each pushbutton is storedin non-volatile memory and maintained through a loss of control power.The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the PUSHBTN 1 RESET set-ting or by directly pressing the associated active front panel pushbutton.It can also be programmed to reset automatically through the PUSHBTN 1 AUTORST and PUSHBTN 1 AUTORST DELAY set-tings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can beused in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breakerlocation (feeder number) must be selected prior to command execution. The selection must reset automatically if con-trol is not executed within a specified time period.• Self-reset mode: In self-reset mode, a user-programmable pushbutton can be set (activated) by asserting the operandassigned to the PUSHBTN 1 SET setting or by pressing the front panel pushbutton. A pushbutton remains active for thetime it is pressed plus the dropout time specified in the PUSHBTN 1 DROP-OUT TIME setting. If the pushbutton is activatedvia FlexLogic, the pulse duration is specified by the PUSHBTN 1 DROP-OUT TIME only. The time the operand remainsassigned to the PUSHBTN 1 SET setting remains On has no effect on the pulse duration.842814A1.CDRUSERLABEL 1 USERLABEL 2 USERLABEL 3 USERLABEL 4 USERLABEL 5 USERLABEL 6 USERLABEL 7 USERLABEL 8 USERLABEL 9 USERLABEL 10 USERLABEL 11 USERLABEL 12 USERLABEL 13 USERLABEL 14 USERLABEL 15 USERLABEL 16USER LABEL USER LABEL USER LABELUSER LABEL USER LABEL USER LABEL7 9 118 10 12USER LABEL1 3 52 4 6USER LABEL USER LABELUSER LABEL USER LABEL USER LABEL842779A1.cdr
