SERVICE AND NORMAL MAINTENANCE

!NOTE

UPON COMPLETING INSTALLATION, MAKE SURE THAT THE PROBE IS TURNED ON AND OPERATING PRIOR TO FIRING UP THE COMBUSTION PROCESS. DAMAGE CAN RESULT FROM HAVING A COLD PROBE EXPOSED TO THE PROCESS GASES.

During outages, and if possible, leave all probes running to prevent condensation and prema- ture aging from thermal cycling.

If the ducts will be washed down during outage, MAKE SURE to power down the probes and remove them from the wash area.

A-9 OVERVIEW

This section describes routine maintenance of the oxygen analyzer probe. Spare parts referred to are available from Rosemount. Probe disas- sembly kit 3535B42G01 contains the required spanner and hex wrenches. Refer to the follow- ing section of this appendix for part numbers and ordering information.

Install all protective equipment covers and safety ground leads after equip- ment repair or service. Failure to in- stall covers and ground leads could result in serious injury or death.

A-10 PROBE RECALIBRATION

The oxygen analyzer system should be cali- brated when commissioned. Under normal cir- cumstances the probe will not require frequent calibration. When calibration is required, follow the procedure described in the Instruction Bulle- tin applicable to your electronics package.

A-11 CELL REPLACEMENT

This paragraph covers oxygen sensing cell re- placement. Do not attempt to replace the cell until all other possibilities for poor performance have been considered. If cell replacement is needed, order cell replacement kit, Table A-3.

The cell replacement kit contains a cell and flange assembly, corrugated seal, setscrews, socket head cap screws, and anti-seize com- pound. Items are carefully packaged to preserve

precise surface finishes. Do not remove items from packaging until they are ready to be used. Spanner wrenches and hex wrenches needed for this procedure are part of an available special tools kit, Table A-3.

Wear heat resistant gloves and cloth- ing to remove probe from stack. Nor- mal operating temperatures of diffusor and vee deflector are approximately 600° to 800°F (316° to 427°C). They could cause severe burns.

Disconnect and lock out power before working on any electrical components. There is voltage up to 115 Vac.

Do not remove cell unless it is certain that replacement is needed. Removal may damage cell and platinum pad. Go through complete troubleshooting procedure to make sure cell needs re- placement before removing it.

a.Disconnect and lock out power to electron- ics. Shut off and disconnect reference air and calibration gas supplies from probe junction box, Figure A-16.Wearing heat re- sistant gloves and clothing, remove probe assembly from stack carefully and allow to cool to room temperature. Do not attempt to work on unit until it has cooled to a comfort- able working temperature.
