Warning Value
This menu lets you set the Warning band width, a positive and negative warning
point relative to the setpoint. If the setpoint changes, the warning points also
change. You can assign separate digital outputs to Hi and Lo Warnings.
Selectable Values: 0 to 255, 35.5, 2.55, .255 or .0255, depending on the way
you set up the Input menus.
Warning High
This menu lets you disable the warning Hi function or set it to the alarm functions.
(The Warning Hi activates if the process value (PV) rises above the deviation
band value, and remains active until the PV goes below the deviation band value
minus the deadband value.)
Selectable Values: Latched, Unlatched, or Off
Warning High Output Number
This menu assigns a digital output which activates when the channel is in high
deviation alarm. The digital output only activates if you have set the high
deviation alarm to On.
Selectable Values: 1 to 34, None
NOTE
All digital outputs are combined. Therefore you can assign more than
one alarm to the same output number, and the output will be On if any
of those alarms is On.
