Figure 36: Reinstalling 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.
24. Make sure that the top case gasket is fully seated in its groove and carefully put the
top case back on the bottom case. If you have any difficulty mating the top and
bottom cases, inspect the placement of the main PCB and the placement of the top
case gasket.
25. Turn the EAGLE 2 upside down and tighten the three case screws to secure the top
case to the bottom case.
