Replacing Gc Module - ABB NGC8206 User Manual

16) Holding the new analytical module at the opening of the enclosure, reconnect
jack J1 and J4, if the auxiliary heater is installed (see
17) 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 the analytical module
are keyed to ensure proper alignment.
18) When the analytical module is in place, tighten the mounting screw.
19) Use
20) Plug the termination panel to the digital controller ribbon cable into the digital
controller assembly.
21) Insert the lithium battery pack into the enclosure between the enclosure and the
thermal flask.
22) Turn on all sample streams, calibration gas and carrier gas.
23) Once the unit is reassembled, apply power to the NGC (Step 6).
24) Follow the Cold Start procedure in Maintenance.
25) Reinstall the front and rear end caps.

5.15 Replacing GC Module

This section presents the procedures for the removal and installation of the GC
module. The module is a completely self-contained unit and is part of the
analytical module. Read through all procedural steps before removing the
assembly.
Verify before beginning the procedure that the module is appropriately rated for
the system voltage. Compare the module voltage to the ID tag located on the side
of the enclosure.

Replacing Digital Controller Complete Assembly
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.
Note that since power was removed from this unit, the NGC
will perform start-up diagnostics and stabilize. If the user has
disabled the start-up diagnostics, they should be enabled
and power cycled to the unit. If power has been withheld
from the unit for an unknown or lengthy period of time, a
complete start-up should be performed.
For more information about enabling the diagnostics in
PCCU, click Diagnostics and then Help.
