WebNov 12, 2024 · The determination of which failure mode to use—upscale or downscale burnout—depends on the use of the transmitter. This selection is made based on making the loop failsafe. For example, if it is a temperature transmitter and it is used for a high temperature interlock, we would select upscale burnout. WebTo compensate for that, a temperature controller will normally go into upscale burnout mode, and drive the furnace burner to low fire or turn down the SCRs. But then, you have to deal with the downtime, rework, or even the potential of losing product.
