19. Using a 5/64” hex wrench, tighten the feed-through set screw.
20. Insert the mounting screw into the analytical module.
21. Holding the analytical module at the opening of the enclosure, reconnect jack J1 and J4, if the
auxiliary heater is installed (see Figure 10-15).
22. Carefully insert the module into the enclosure, rotating the module to ensure the rear
components clear the manifold interface on the inside area of the feed-through assembly. The
feed-through manifold interface and analytical module are keyed to ensure proper alignment.
23. When the analytical module is in place, tighten the mounting screw.
24. Follow the instructions in section 10.15 to replace the digital controller complete assembly.
25. Plug the termination panel to the digital controller ribbon cable and into the digital controller
assembly.
IMPORTANT NOTE: Note that the termination panel to digital controller ribbon cable pin 1 wire is
not red. On the digital controller board, the red edge (pin 1) of the cable should plug onto pin 50,
the right side of plug. The plug is keyed; do not force the plug into the connector.
26. Insert the lithium battery pack into the enclosure between the enclosure and the thermal flask.
27. Once the device is reassembled, apply power to the analyzer.
28. Reinstall the front and rear end caps.
IMPORTANT NOTE: Since the power was removed from this device, the analyzer will perform
startup diagnostics and stabilize. If the user has disabled the startup diagnostics, they should be
enabled and power cycled to the device. If the power has been withheld from the device for an
unknown or lengthy period of time, a complete startup should be performed.
For more information on enabling the diagnostics in PCCU, click Diagnostics and then Help.
10.20 Replace the lithium battery
This section presents the procedures for the removal and installation of a new lithium battery. The
lithium battery is inside the front end cap and is wedged between the thermal flask and the enclosure
wall. Read all procedural steps before removing the assembly.
To replace the lithium battery:
NOTICE – Equipment damage or loss of data. Do not remove power to the device. Loss
of power to the device will perform a cold start. All data and configuration files will be lost.
1. On the Analyzer Operation screen, click Hold under Next Mode. When the device completes the
current cycle and enters hold, continue to the next step.
2. Collect data from the device.
3. Back up the configuration files following the instructions detailed in section 10.6.
NOTICE – Equipment damage. As with all electronic components, caution should be used
when handling the boards. Static electricity can potentially damage board components,
voiding any warranty.
4. Gain access to the digital controller assembly by loosening the countersunk hex socket locking
set screw in the front end cap using a 1/16” hex wrench and then unscrewing the end cap.
5. Unplug the lithium battery connector from the J5 receptacle on the digital controller board (see
Figure 10-19).
6. Plug in the replacement lithium battery to J5 on the digital controller board.
7. Insert the lithium battery pack into the enclosure between the enclosure and the thermal flask.
8. Using the Lithium battery status instructions, verify that the battery status is ok before
proceeding.
9. Reinstall the front end cap.
