GE Multilin F60 Feeder Protection System 5-555 SETTINGS 5.2 PRODUCT SETUP5Figure 5–8: USER-PROGRAMMABLE PUSHBUTTONS (ENHANCED FACEPLATE)The user-configurable pushbuttons for the standard faceplate are shown below.Figure 5–9: USER-PROGRAMMABLE PUSHBUTTONS (STANDARD FACEPLATE)Both the standard and enhanced faceplate pushbuttons can be custom labeled with a factory-provided template, availableonline at http://www.gedigitalenergy.com/multilin. The EnerVista UR Setup software can also be used to create labels forthe enhanced faceplate.Each pushbutton asserts its own “On” and “Off” FlexLogic™ operands (for example, PUSHBUTTON 1 ON and PUSHBUTTON1 OFF ). These operands are available for each pushbutton and are used to program specific actions. If any pushbutton isactive, the ANY PB ON operand will be 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 PUSHBTN1 LED CTL setting.The pushbuttons can be automatically controlled by activating the operands assigned to the PUSHBTN 1 SET (for latched andself-reset mode) and PUSHBTN 1 RESET (for latched mode only) settings. The pushbutton reset status is declared when thePUSHBUTTON 1 OFF operand is asserted. The activation and deactivation of user-programmable pushbuttons is dependenton whether latched or self-reset mode is programmed.• 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 pushbutton maintains the set stateuntil deactivated by the reset command or after a user-specified time delay. The state of each pushbutton is stored innon-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 pushbutton will remain active for the time it is pressed (the pulse duration) plusthe dropout time specified in the PUSHBTN 1 DROP-OUT TIME setting. If the pushbutton is activated via FlexLogic™, thepulse duration is specified by the PUSHBTN 1 DROP-OUT TIME only. The time the operand remains assigned to the PUSH-BTN 1 SET setting has no effect on the pulse duration.The pushbutton is reset (deactivated) in self-reset mode when the dropout delay specified in the PUSHBTN 1 DROP-OUTTIME setting expires.The pulse duration of the remote set, remote reset, or local pushbutton must be at least 50 ms to operate the push-button. This allows the user-programmable pushbuttons to properly operate during power cycling events and vari-ous system disturbances that may cause transient assertion of the operating signals.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.cdrNOTE
