Analog Status Low Alarm Conditional Disable

I am trying to conditionally disable alarm so it is only enabled while a certain piece of equipment is operating. I have the built in low alarm configured as such

When I right-click on the displayed analog tag it shows Disable Low Alarm as checked, but the alarm is still active in my alarm history. How do I keep this disabled while not operational?

Thanks.

Click on the window icon to edit the expression and check/uncheck the option box so the expression evaluates on change and not only on start condition.

In your case, you likely have a race condition when the app is initializing.

Cool, I didn't realize we have that option fixed in this menu but it makes sense here. I would suggest that you still have a race condition here where you are likely having the alarm trigger, as well as the, disable set at about the same time (let me know if this isn't the case but I did some testing on my own installation as things worked as I'd expect.)

I suspect you can avoid the race condition by adding a slight delay to your alarm. Try adding a three-second alarm delay to ensure that your disable function has time to set the disable property before the alarm condition becomes true.
