IMPORTANT NOTE:
Note that since power was removed from this device, the analyzer will
perform startup diagnostics and stabilize. If the user has disabled the startup diagnostics, it 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.

10.24 Replace the termination panel to the digital
controller cable
If the termination panel to digital controller cable becomes damaged and requires replacement, follow
these instructions. Typically, the user would change the cable while performing another procedure,
but the instructions will start and finish as a complete procedure.
To replace the panel:
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
.
4.
Using the
instructions, verify the battery status is ok before proceeding.
5.
Turn off all the sample streams, calibration gas and carrier gas.
6.
Disconnect or remove the power from the device externally or remove the J1 connector from
the termination panel.
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.
7.
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.
8.
Following the instructions detailed in section
, remove the assembly (see
). If
weather and circumstances permit, the digital controller assembly may be suspended by the
cables to eliminate stress on the cable connections and you can move to step 10.
9.
Carefully unplug the cable to the termination panel, leaving the lithium battery plugged in, and
set the digital controller assembly aside on a clean, lint-free surface.
10. Using a 5/16” hex wrench, loosen the mounting screw holding the analytical module in place
until the module can be slowly lifted from the enclosure, taking care to not pull the wires
attached to the rear of the assembly (see
11. Detach the analytical module rear face jack J1 and J4, if the auxiliary heater is installed.
12. Set the module on a clean, lint-free surface.
13. Reach into the enclosure through the front opening and unplug the ribbon cable from the rear
of the termination panel J4.
14. On the replacement cable, verify the orientation by viewing the keyed receptacle on the
termination panel and cable. Insert the plug into the J4 connector.
15. Verify that the gasket on the feed-through assembly manifold interface is in place and in good
condition. If the gasket has fallen off inside the enclosure or is stuck to the GC module, replace
it onto the feed-through manifold interface, ensuring that the gasket does not cover the gas
portholes.
16. Insert the mounting screw into the analytical module.
17. Holding the analytical module at the opening of the enclosure, reconnect jack J1 and J4, if the
auxiliary heater is installed (see
).
18. Carefully insert the module into the enclosure, rotating the module to ensure that 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 the proper
alignment.
19. When the analytical module is in place, tighten the mounting screw.
20. Follow the instructions in section
to replace the assembly.
21. Plug the termination panel into the digital controller ribbon cable and then into the digital
controller assembly.
