What to do if Omron E5CN Temperature Controller shows input error (S.Err display)?
- MMarisa RobinsonAug 27, 2025
If the Omron Temperature Controller displays 'S.Err', it indicates an input error. This may be due to an input type mismatch. Verify that the sensor type matches the configured input type and reset it correctly. Another potential cause is improper thermometer installation. Ensure the thermometer is correctly installed with the correct polarity and in the appropriate location.
