5.2 PRODUCT SETUP

PATH: SETTINGS PRODUCT SETUP
 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 C30 is ordered with the twelve
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. 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 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.
