Alarm Deadband
You can configure an alarm deadband to work with these alarms. The deadband
lets the process alarm status bit remain set, despite the alarm condition
disappearing, as long as the input data remains within the deadband of the
process alarm.
The following graphic shows input data that sets each of the four alarms at some
point during module operation. In this example, latching is disabled; therefore,
each alarm turns Off when the condition that caused it to set ceases to exist.

To see where to set the Alarm Deadband on the 5069-IF8 module, see page 93.
