GE Multilin L60 Line Phase Comparison System 5-495 SETTINGS 5.2 PRODUCT SETUP55.2.12 CONTROL PUSHBUTTONSPATH: SETTINGS PRODUCT SETUP CONTROL PUSHBUTTONS CONTROL PUSHBUTTON 1(7)There are three standard control pushbuttons, labeled USER 1, USER 2, and USER 3, on the standard and enhanced frontpanels. These are user-programmable and can be used for various applications such as performing an LED test, switchingsetting groups, and invoking and scrolling though user-programmable displays.Firmware revisions 3.2x and older use these three pushbuttons for manual breaker control. This functionality has beenretained – if the breaker control feature is configured to use the three pushbuttons, they cannot be used as user-program-mable control pushbuttons.The location of the control pushbuttons are shown in the following figures.Figure 5–4: CONTROL PUSHBUTTONS (ENHANCED FACEPLATE)An additional four control pushbuttons are included on the standard faceplate when the L60 is ordered with the twelve user-programmable pushbutton option.Figure 5–5: 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.
