To find the cause of an alarm, on each screen in the system the [Alarms] key appears in
the lower left corner of the display. The color of this key will reflect the severity level of
the most severe active alarm. Press the [Alarms] key to navigate to a screen where the
alarm list will be displayed. The list will display all unacknowledged alarms. Alarms
whose state has cleared will also appear in the list if they have not been acknowledged.
Once acknowledged, the cleared alarms will be removed from the list.
The cause of the alarm and the time that it occurred will be displayed on the screen. The
user can navigate the alarm list using the [Up] and [Down] keys. The [ACK] key when
pressed, acts to acknowledge all of the alarms in the list.
Next to the alarm list is text box which provides support information for the currently
selected alarm. Scrolling through the alarm list, the text box will update with the appro-
priate support information.
