GE Multilin N60 Network Stability and Synchrophasor Measurement System 5-495 SETTINGS 5.2 PRODUCT SETUP5The location of the control pushbuttons are shown in the following figures.Figure 5–5: CONTROL PUSHBUTTONS (ENHANCED FACEPLATE)An additional four control pushbuttons are included on the standard faceplate when the N60 is ordered with the twelveuser-programmable pushbutton option.Figure 5–6: CONTROL PUSHBUTTONS (STANDARD FACEPLATE)Control pushbuttons are not typically used for critical operations and are not protected by the control password. However,by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.Each control pushbutton asserts its own FlexLogic™ operand. These operands should be configured appropriately to per-form the desired function. The operand remains asserted as long as the pushbutton is pressed and resets when the push-button is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton manipulation will be recognized byvarious features that may use control pushbuttons as inputs.An event is logged in the event record (as per user setting) when a control pushbutton is pressed. No event is logged whenthe pushbutton is released. The faceplate keys (including control keys) cannot be operated simultaneously – a given keymust be released before the next one can be pressed.The control pushbuttons become user-programmable only if the breaker control feature is not configured for manual controlvia the USER 1 through 3 pushbuttons as shown below. If configured for manual control, breaker control typically uses thelarger, optional user-programmable pushbuttons, making the control pushbuttons available for other user applications.Figure 5–7: CONTROL PUSHBUTTON LOGICControl pushbuttons842813A1.CDR842733A2.CDRPICKUPALARMTRIPTEST MODETROUBLEIN SERVICESTATUSUSER 3USER 2USER 1RESETEVENT CAUSENEUTRAL/GROUNDPHASE CPHASE BPHASE AOTHERFREQUENCYCURRENTVOLTAGETHREESTANDARDCONTROLPUSHBUTTONSUSER 7USER 6USER 5USER 4FOUR EXTRAOPTIONALCONTROLPUSHBUTTONS842010A2.CDRCONTROL PUSHBUTTON1 FUNCTION:SYSTEM SETUP/BREAKERS/BREAKER 1/BREAKER 1 PUSHBUTTON:CONTROLSYSTEM SETUP/BREAKERS/BREAKER 2/BREAKER 2 PUSHBUTTON:CONTROLSETTINGSETTINGSTIMER FLEXLOGIC OPERANDEnabled=1Enabled=1When applicableEnabled=1RUNOFFONAND100 msec0 CONTROL PUSHBTN 1 ON{
