PUSHBUTTON 1
MESSAGE
The three standard pushbuttons located on the top left panel of the faceplate are user-programmable and can be used for
various applications such as performing an LED test, switching setting groups, and invoking and scrolling though user-pro-
grammable displays, etc. Firmware revisions 3.2x and older use these three pushbuttons for manual breaker control. This
functionality has been retained – if the Breaker Control feature is configured to use the three pushbuttons, they cannot be
used as user-programmable control pushbuttons. The location of the control pushbuttons in the following figure.
An additonal four control pushbuttons are included when the L60 is ordered with twelve user programmable pushbuttons.
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,
configured appropriately to perform the desired function. The operand remains asserted as long as the pushbutton is
pressed and resets when the pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton
manipulation will be recognized by various 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 when
the pushbutton is released. The faceplate keys (including control keys) cannot be operated simultaneously – a given key
must 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 con-
trol via the User 1 through 3 pushbuttons as shown below. If configured for manual control, Breaker Control typically uses
the larger, optional user-programmable pushbuttons, making the control pushbuttons available for other user applications.
