Alarm Configuration
The alarm configuration menu is for defining settings for each of the sensor’s alarms.
Enable:
Tick the box in the Enable column to enable an alarm.
Sensor:
Choose the sensor which you want to activate the alarm for from the list.
Trigger:
Enter a value in engineering units that you want to use as the trigger point for the alarm. When the scaled
value crosses this limit the alarm will become active. The trigger direction is determined by the reset level.
Reset:
Enter a reset level for the alarm.
Duration:
This is the time in seconds to delay alarm activation. This can be used to implement alarm hysteresis for
analogue data sources that vary. If the data source is one of the internal counters, then this time is used to
totalise individual sample values. If the total over the given alarm duration is above the trigger level then an
alarm is generated. Typically this feature is used for rainfall alarms.
