Figure 32: Reinstalling the Electrode Lamp

16. Twisting the lamp slightly during insertion will help to ensure the lamp

window is snug against the stack's front electrode. The lamp should be

supported by the O-ring.

17. Continuing to hold the electrode stack between your forefinger and

thumb, carefully insert the lamp into the lamp cavity in the sensor

ensuring that the lamp remains in position.

18. Press in the electrode stack firmly to ensure that the stack wing clips are

engaged and the faces of the stack and sensor body are flush.

19. Carefully line up the PID sensor’s pins with the sockets in the bottom of

the sensor adapter and gently lower the sensor into the adapter until you

feel it contact the bottom.

20. Do not attempt to push the sensor in farther once it makes contact with

the bottom of the adapter until you are sure that the sensor’s pins are

engaged with the sockets. If you feel that the pins did not engage the

sockets, slightly rotate the sensor back and forth without putting pressure

on it until you feel the pins engage the sockets.

21. Push the sensor into the sockets until it bottoms out.

22. Insert the sensor adapter into the PID flow chamber and push it in until it

bottoms out.

23. Confirm that the main PCB is seated in its slots and that its bottom edge

is resting on the bottom of the bottom case. If the main PCB is not seated

properly, it may be damaged when the top case is re-installed.
