Trouble Type

This menu lets you turn off the Trouble Alarm, or set it to the Alarm Function.

Selectable Values: Off, Latched, Unlatched

Trouble Output Number

This menu lets you assign the digital output that activates when the channel is in
Trouble.

Selectable Values: None, 1 to 34

Alarm Deadband

This menu lets you set an alarm deadband. This deadband value applies to the
high process, low process, high deviation, and low deviation alarms for the
channel you are editing.

The alarm deadband sets the hysteresis of the alarm action which is used to
avoid intermittent alarms as the PV returns to a normal state.

Selectable Values: 0 to 255, 25.5, 2.55, .255, or .0255 depending on your input
menu setup.

NOTE
All digital outputs are combined. Therefore you can assign more than one
alarm to the same output number, and that output will be On if any of those
alarms is On.
