When an alarm is first registered, it appears on the Alarm Log display and is
highlighted in yellow. If the alarm is short term (that is, two seconds or less), the alarm
text is not highlighted after approximately two seconds. If the alarm continues longer
than two seconds, the text remains yellow and the alarm duration is incremented. When
the next alarm occurs, the previous alarm moves down one position.
Alarm Status
The alarm status screen contains detailed information concerning alarm status
indicators. This information is separated into columns sorted by alarm name, whether
or not the alarm is enabled, lower and upper limits, thresholds, and duration, and total
number of alarms. The alarm name text can appear in a colored state. The colored
states are:
•
White
: indicates alarm is not enabled.
•
Green
: indicates alarm is enabled and not exceeding alarm limits.
•
Red
: indicates the alarm is enabled and exceeding an alarm limits.
There is a two-second persistence for any Alarm Name color change.
Use the same navigation buttons to scroll through the alarm status list as for the alarm
log list (see page 55).
An alarm status display diagram is shown in
Figure 4-35
on page 56. The diagram
illustrates the general location for the various alarm status display fields.
