3.13.4 Alarm Display Viewing Sequence
When the alarm scroll key is pressed to initiate viewing of the alarm displays, the sequence in
which the displays appear depends on the instrument state, type of alarm, alarm priority, and
whether the alarm has been acknowledged.
Instrument In Run State
When the state is RUN the viewing sequence is:
1. Unacknowledged diagnostics in the order of their location in the data base.
2. Unacknowledged quality alarms in order of highest priority to lowest priority (priority
number 1 - 255).
3. Unacknowledged process alarms in order of highest priority to lowest priority (priority
number 1 - 255).
4. Any active, quality alarms not viewed in Step 2 in the order of highest priority to lowest
priority (priority 0 - 255).
*
NOTE: Priority 0 alarm displays appear only in Steps 4 and 5 because 0 priority
does not have an unacknowledged condition.
5. Any active process alarms not viewed in Step 3 in order of highest priority to lowest
priority (priority number 0 - 255).
6. Active, but already acknowledged, diagnostics in the order of their location in the data
base.
7. When the above sequence has been completed the [ALARM] [END] display appears, and
pressing the R/L [RET] key returns the runtime display that was visible before entering
the viewing sequence.
Instrument Not In Run State
When the state is not RUN the viewing sequence is:
1. Unacknowledged diagnostics in the order they are in the database.
2. Active, but already acknowledged, diagnostics in the order they are in the database.
3. When the above sequence has been completed the [ALARM] [END] display appears, and
pressing the R/L [RET] key returns the runtime display that was visible before entering
the viewing sequence.
Alarm Activity During A Viewing Sequence
After viewing of the unacknowledged diagnostic alarm displays is started, any new diagnostic
that is stored in the data base area that has already been searched is not displayed until the
next viewing sequence. After viewing of the unacknowledged process alarm displays is
started, any new process alarm which becomes active is not displayed until the next viewing
sequence.
