Control Pushbuttons - GE N60 Instruction Manual

PRODUCT SETUP
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.
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 are shown in the following figures.

An additional four control pushbuttons are included on the standard faceplate when the N60 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.
