When in the “Disabled” mode, minor alarms will not assert a FlexLogic operand, write to the event recorder, or display tar-
get messages. Moreover, they will not trigger the
ANY MINOR ALARM
or
ANY SELF-TEST
messages. When in the “Enabled”
mode, minor alarms continue to function along with other major and minor alarms. Refer to the
Relay self-tests
section in
chapter 7 for additional information on major and minor self-test alarms.

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 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.
Figure 5–7: CONTROL PUSHBUTTONS (ENHANCED FACEPLATE)
An additional four control pushbuttons are included on the standard faceplate when the B30 is ordered with the twelve user-
programmable pushbutton option.
Figure 5–8: 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 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.
