5.14 Replacing Analytical Module
This section presents the procedures for removal and installation of the analytical
module. The module is a completely self-contained unit and is part of the
NGC8200. Read through all procedural steps before beginning disassembly.
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.
When the analytical module is removed, the module should
be placed on a clean, dirt-free work surface. Care should be
taken that gas ports are free from lint or dust particles.
Totalflow strongly suggests that the GC replacement module
be kept in a sealed, static free envelope until the last
possible moment before installation.
It is important that the bottom surface of the module be
placed on a clean, lint free cloth to prevent components from
being scratched, damaged or contaminated.
To return this assembly to Totalflow service for warranty or
repair, please contact Totalflow customer service for an RA
number.
5.14.1 Instructions
1)
On the Analyzer Operation
screen, click
Hold
under Next Mode. When the
unit completes the current cycle and enters hold, continue to the next step.
2)
Collect data from the unit.
3)
Back up the configuration files, following the instructions detailed previously in
the section,
Backing Up Configuration Files (Save)
4)
Using the Lithium Battery Status
instructions, verify the battery status is OK
before proceeding.
5)
Turn off all sample streams, calibration gas and carrier gas.
6)
Disconnect or remove the power from the NGC unit externally, or remove the J1
connector from the termination panel.
As with all electronic components, caution should be used
when handling 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 then
unscrewing the end cap.
8)
Following the instructions detailed previously in the section,
, remove the assembly. If weather/circumstances permit,
the digital controller assembly may be suspended by the cables to eliminate
stress on the cable connections. Skip to step 10.
9)
Carefully unplug the cable to the termination panel, leaving the lithium battery
plugged in. Set the digital controller assembly aside on a clean, lint-free surface.
10)
Using a 5/16” hex wrench, loosen the mounting screw (see
) holding
the analytical module in place until the module can be slowly lifted from the
enclosure, taking care to not pull or stress wires attached to the rear of the
assembly.
