Deadband
Deadband is an area of the alarm range where no reset action occurs. The purpose of the deadband is to prevent unintentional activation-deactivation cycles.
For example, an out of range alarm has an upper limit of 10 and the deadband is 2. The monitored variable must be equal to or fall below 8 (10-2) before the triggered alarm is reset.
The monitored variable has to reach the limit of the deadband before the alarm is reset.
Deadband can be set for out of range alarms and out of reference range alarms.
