Alarm Deadband incorrect

The Alarm Deadband is too large for the current settings of the Low and High Alarms. Enter an Alarm Deadband that is between the High Alarm and the Low Alarm and that does not overlap. In other words:

Deadband < (High Alarm – Low Alarm)/2

The deadband is a value where an alarm, once set, will not disable as long as the input value remains within the deadband range of the alarm trigger point. (This value, in combination with the process alarms, creates the range.)
