Control Pushbuttons - GE F35 Instruction Manual

CHAPTER 5: SETTINGS
When in the Disabled mode, minor alarms do not assert a FlexLogic operand, write to the event recorder, or display target
messages. Moreover, they do not trigger the ANY MINOR ALARM or ANY SELF-TEST messages. When in Enabled mode,
minor alarms continue to function along with other major and minor alarms. See the Relay Self-tests section in chapter 7
for information on major and minor self-test alarms.

 CONTROL
 PUSHBUTTON 1
There are three standard control pushbuttons, labeled USER 1, USER 2, and USER 3, on the standard and enhanced front
panels. These 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-programmable displays.
The location of the control pushbuttons are shown in the following figures.
An additional four control pushbuttons are included on the standard faceplate when the F35 is ordered with the 12 user-
programmable pushbutton option.
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. Each operand need to be configured appropriately to perform
the required function. Each 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 is recognized
by various features that can use control pushbuttons as inputs.
