How to Alter a Digital Firing in Progress
Someone asked, “How do I override a digital controller during firing? Can I press Stop but somehow continue firing?”
There are several ways to override a digital controller, depending on the brand. One method is to just press Stop. Make a change in the program, such as adding another segment, and press Start again. The controller will continue firing, taking up where it left off before. You might want to double-check your manual, but this would apply to most brands of controllers.
When you turn the controller back on after pressing Stop, the controller will go to the first segment that encompasses the current kiln temperature. If the kiln is at 1500 degrees F when you press Start, and segment 2 starts at 1400 degrees and ends at 1700, then the controller would begin firing at segment 2. This is the way most controllers operate.
Some models, such as the latest Sentry 12-key, allow you to edit a program during firing. Press the 4 key. The display will show the target temperature of the current segment. Change the temperature if needed. Then press Enter. The display will then show the hold time of the current segment. Change the time, if needed, and press Enter. The kiln will resume firing.
Some controllers, such as the Sentry 12-key, also have an "add time" feature that allows you to add time to a soak without having to press Stop to make the change.
Wishing you a great fall season,
