    What to do if the Omron E5 Z shows a large temperature error or S.Err display?
    • J
      Joanne AlexanderAug 12, 2025
      If you are experiencing a large temperature error or seeing an 'S.Err' display on your Omron Temperature Controller, it could be due to a mismatch in the input type setting. To resolve this, verify the sensor type you are using and then reset the input type on the controller to match. Another potential cause is improper installation of the thermometer. Double-check the thermometer's installation location and polarity, ensuring it is correctly installed.

      If an A/D converter error occurs, first note the error, then reset the power to the Omron Controller. If the display does not change, the Controller may need replacement. If resetting the power removes the error, it is possible that the error was caused by noise. In this case, check for potential sources of noise.

    What to do if Omron Controller shows memory error?

      If a memory error occurs, reset the power to the Omron Controller. If the display doesn't change after resetting the power, replacement of the unit is necessary. However, if the error is removed, it's possible that the original error was caused by noise. In that case, check the surrounding environment for potential noise sources.
