What model of Med-T pump do you have? Have you read the user’s manual for anyplace it mentions a “no delivery alarm”? Have you done a Google search for your pump model number and a no delivery alarm?
Here’s one webpage I found doing a “no delivery alarm Medtronic pump” Google search.
This TuD thread discusses symptoms much like yours.
You may search the TuDiabetes site by clicking the magnifying glass icon in the upper right and then inserting a search term. “No delivery” for Medtronic pumps contains several entries.
