Other Considerations

• TCR sample probe line pressure should be as close to 1-atmosphere as

possible to reduce sample transport lag times due to “line pack”. Sample

pressure at the NGC should be 15 ± 2 PSIG (103 ± 14 Kpa).

• To maintain this pressure at the NGC filters, it may be necessary to increase

TCR sample probe pressure to a value greater than 15 PSIG. Pressure is

dependent on sample transport tubing length between the TCR sample probe

and analyzer.

• Be sure to use tubing electrical isolators on sample tubing when connected to

pipelines that are not isolated from cathodic protection.

1.15 VGA Display (Optional Equipment)

The display board provides a ¼ panel, VGA monochromatic display to monitor the

process and results. It also provides six magnetic switches to allow a user to

navigate through various screens of data and control the processes (stop

operation, start operation and calibrate).

If the NGC is configured with the front panel display, available screens and user

defined screens may be navigated using the display magnet (Part No. 1801755-

001).

The optional VGA display features:

• ¼ panel VGA display circuit board.

• 2 LED Status Indicators, User Programmable (default left LED- flashing light

indicates a fault alarm, and a solid light indicates a warning alarm. Right LEDsolid light indicates unit is NOT in auto run mode.)

• User interface, with hall-effect magnet navigation, for monitoring NGC8200

operation.

Figure 1—20 shows the flow of information accessible through the display.
