CHAPTER 4: INTERFACES
FRONT PANEL INTERFACE
Figure 4-39: 3x4 annunciator page with two active windows
To display the annunciator, press the Home pushbutton, then the Annunciator Tab pushbutton. If there is one or more
4
window in alarm or requiring reset, the annunciator page showing the first of these opens. Otherwise the first annunciator
page opens.
Alarms do not display automatically. Instead set the Home page and/or rolling pages to annunciator pages to view them
by default.
When any annunciator page displays, the Tab pushbutton labels populate with other annunciator pages. Tab label text for
each annunciator page is configurable and displays in the header and Tab label. The current page has a blue Tab label.
Tab labels for annunciator pages that have an active window (that is, on, latched, or unacknowledged) are red. Pages
where alarms are not triggered have a grey Tab label. Pages that have no configured windows do not have Tab
pushbuttons and do not display.
The Up, Down, Left, and Right pushbuttons cause the selection to move one window in the indicated direction. Pressing the
Right pushbutton past the last window in a row scrolls the display to any next annunciator page, not the next row. The
behavior is similar for the other pushbuttons, for example pressing the Up pushbutton when a window in the top row is
selected, displays any previous page. If no previous page exists, no action occurs.
Annunciator windows are statically positioned, so that all windows are visible no matter their state.
Alarm types of each window can be configured as Self Reset, Latched, or Acknowledgeable. In Self Reset mode, the
window lighting follows the state of the configured FlexLogic operand. The self-reset mode alarm sequence conforms to
ISA-18.1-1979 (R2004) standard type A 4 5 6.
