What to do if Seitron Control Unit displays a symbol and beeps with a flashing red power supply led?
- JJohn MillerAug 2, 2025
If your Seitron Control Unit shows a symbol, beeps, and the red power supply LED flashes quickly while a probe number flashes on the display, it indicates an anomaly with the probe. The display shows the number of the damaged probe and the type of anomaly present. Possible causes and solutions include: * **Missing, improperly wired, or open probe:** Correct the wiring or replace the probe. * **Temperature below -31°C:** Check probe S_3 for accuracy. * **Short circuit or temperature above 200°C:** Check for a short circuit or replace the probe. * **Temperature between -30°C and -20°C:** Check temperature readings. * **Temperature between +180°C and +199°C:** Inspect the probe and environmental conditions.
