Exhaust Lambda Warning

I have read the help files several times and I still don't have a firm understanding of the differences under the Delay settings for the Exhaust Lambda Warning.

There is:

Enable and Activate. I believe the combined times of both delay when the warning comes on. But what is the difference between Enable and Activate?

Enable is when the Warning Conditions will be tested (ie, check that Lambda is between Minimum and Maximum). Activate, is when the Warning becomes active after the conditions become true. You don't want the alarm to be active on every little spike in Lambda, so you provide a delay to make sure it's a real warning condition.
