Error messages on the control unit display indicate problems with the op-
eration of the analyzer. Use this section to see the types of problems your
error message indicates, then go to the "Diagnostic Checks" section at the
end of this chapter for help on how to perform diagnostic checks to pin-
point the problem area. Note that you should always perform the easiest
checks first. Only perform the more difficult checks if the easiest checks
don't locate the problem.
Cell is Over Temp
This error message indicates that the sensor temperature is 30 °C or more
over its correct operating temperature. The software shuts off the furnace
until the temperature returns to a normal operating range.
If this message soon goes away, it indicates that the temperature has re-
turned to an acceptable range. If there is a problem with the sensor tem-
perature control system, you will see another error message after this mes-
sage appears.
Combustibles Cal Error
This error message indicates that the combustibles detector calibration failed
because of an abnormally low signal. Once this error occurs, calibration of
the system is aborted. This message indicates a problem either with your
calibration setup or the combustibles detector.
Excessive Cal Error
If a primary calibration cannot correct the sensor temperature within the
software's allowable limits, this message is displayed to indicate the pri-
mary calibration has failed. This message could indicate one of the follow-
ing problems:
Calibration gas setup problem
Process pressure incorrectly entered
Failed cell
Leak or plug in plumbing
