It is always the last alarm that is displayed. After the last alarm has been acknowledged and
thereby sent to the alarm queue, the next alarm in turn appears for acknowledgment.
In addition to this, all alarm events are collected in an historical alarm log, see section
5.9.3.
5.16.2
Alarm during delay
Alarms can be delayed for the purpose of suppressing short-term variations.
Normally only the alarm output relays are affected by the delay. But the
Show
alarm parameter can be used to also delay the alarm message and
“Alarm” lamp, see section
5.9.2.6.
The alarm can already be acknowledged at this stage.
Irrespective of the acknowledgement happening or not, the alarm will disappear without trace if
the alarm condition ends before the delay time has expired, regardless of the return option
selected.
5.16.3
Active alarm
Active alarm means that the delay period has passed and that the alarm
condition is still met.
As long as the alarm remains active, the alarm message remains and is
waiting for acknowledgment.
As soon as the alarm is acknowledged, it is moved to the alarm queue.
5.16.4
Inactive alarm
Inactive alarm means that the delay period has passed but the alarm
condition is no longer met.
An alarm with the return option
Automatic return
, clears immediately when
the alarm condition ends. It will therefore never be shown with the
Inactive
status.
If the alarm has the
Return after acknowledgement
return option instead, the alarm remains until it
is acknowledged. Following acknowledgement it is moved to the alarm queue.
5.16.5
Alarm queue
Acknowledged alarms that are still
active are collected in an alarm
queue. When all alarms have been
acknowledged, the initial screen
can therefore appear as shown in
the left box. You can use the “
↓
”
and “
↑
” buttons to browse through the alarms in the queue.
After the queue number, a symbol appears that specifies the current alarm status in the following
way:
*
Specifies that the alarm is active
.
Specifies that the alarm is under delay
Blank Specifies that the alarm is inactive
The alarm queue can store up to 20 alarms.
