Common Operator Errors
These are some common errors to avoid; if they are avoided, your analyzer will
operate with a minimum of maintenance and troubleshooting.

If your process is running and the analyzer is installed on the process, the ana -
lyzer must have power applied to it to prevent plugged plumbing and sensor
component damage.

Do not use pipe dope or any other contaminant that gives off combustible vapor
on any joints of the sample tubing.

For O

calibration gases, Do not use calibration gases to check Thermox analyz -
ers if they contain a mixture of oxygen and combustibles.

Always introduce calibration gases at the recommended flow rate.

When working on the plumbing inside the sensor cabinet, turn the power off -
the oxygen cell heater has exposed windings and a short to the plumbing will
blow the fuse and could damage the furnace or thermocouple.

Caution should be used if performing maintenance on the sensor while the
process is running. Removing any part of the sensor can allow process gases
and gases of high temperature to escape into the sensor.

Do not handle the cell excessively. Do not try to clean the cell except by rins -
ing. If you need to handle the cell, grasp by touching the seal fitting at the top;
never touch the bare part of the cell.

Do not remove a cell or type “K” thermocouple that you may want to use again
when the inside of the furnace is still hot - severe thermal shock can be destruc -
tive to either of them.

Always replace the metal cell O-ring when replacing the oxygen cell.
