Diagnostics Checks

This section shows you how to check different sensor areas for possible
problems. See the "Error Messages" section for help on what checks you
should perform based on the error message you see. In addition, if you
don't see an error message, yet feel your readings are inaccurate, you may
also want to check the "General Troubleshooting" section that follows. We
recommend that the thermocouple millivolts and cell millivolts be displayed
during troubleshooting as a troubleshooting aid (see the "Display" section
in Chapter 4 for help on how to display these items). This information will
be helpful should you need to contact the factory for assistance. Be sure to
always include your analyzer model and serial number when calling the
factory for technical support.
Diagnostic checks are broken down as follows:
Wiring Checks
Thermocouple Checks
Calibration Setup Checks
AC Power Checks
Furnace Checks
Process Pressure Checks
Cell Checks
Exercise care when working on the sensor. Turn off power, allow
!
the unit to cool, and wear gloves.
WARNING
Wiring Checks
Interconnecting wiring problem
Make sure all wiring connections between the control unit and the sensor
are terminated to the proper locations and are seated properly. This in-
cludes ensuring that sets of wires are not reversed, and that the cable is not
damaged or melted.
