Alarm Log
The Alarm Log selection option enables the Alarm Log display. The Alarm Log display lists all the alarms,
the date, time, time code, duration, and peak value. The alarm list begins with the most recent alarm
and can hold a maximum of 100 alarms.
An Alarm Log display diagram is show and described in Alarm Log Display (on page 91). The diagram
illustrates the general location for the various alarm fields.
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 as follows:
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
Alarm Log Display).
