X-320M™ User's Manual Installation and Setup
High Alarm
This setting is used to set the trigger point for a high alarm condition. The alarm is triggered when
the value at the sensor exceeds the High Alarm Value. The default High Alarm is
20
.
Low Alarm
This setting is used to set the trigger point for a low alarm condition. The alarm is triggered when the
value at the sensor drops below the Low Alarm Value. The default Low Alarm is
10
.
Deadband
The Deadband prevents alarms from triggering excessively when the sensor measurement
vacillates around the trigger point.
With High Alarms, the measurement must fall below the High Alarm point minus the Deadband
before the High Alarm will be triggered again. Likewise, the Deadband on the Low Alarm requires
the measurement to rise above the Low Alarm point plus the deadband before the Low Alarm will be
triggered again.
For example, if the Deadband is set to .5 inHg, and a High Alarm occurs at 31 inHg, the alarm will
not trigger again until the barometric pressure first drops below 30.5 inHg (31 - 0.5 inHg), as shown
in the figure below. The default Deadband is _____. This can be set from _____ to ______.
