6-4 IDENTIFYING AND CORRECTING FAULT INDICATIONS

A fault in the operation of the Two-Wire In Situ Oxygen Analyzer is indicated by the faulted op- eration display. If no faults exist, the display will indicate NONE. Information on the current fault is found under the DIAGNOSTICS MENU as detailed in Section 3, STARTUP AND OPERATION.

The following paragraphs describe the faults, possible causes, and corrective actions. Refer to Figure 6-4 as needed for test points and wir- ing information.

NOTE

Allow adequate time for the oxygen probe to reach its operating tempera- ture [approximately 500°C (932°F)] be- fore investigating a fault. The SHOW FAULTS screen of the DIAGNOSTICS menu will indicate a fault until the unit reaches operating temperature.
