The Totalflow NGC8206 has an extensive built-in list of tests which are performed

each time the unit is started. This start-up testing may be disabled, but Totalflow

recommends that it be left enabled. These diagnostics consist of four areas of

testing:

• Carrier Pressure Regulator Test

• Oven Temperature Test

• Processor Control Test

• Stream Test

These start-up tests may also be performed on a regular schedule. Please see the

PCCU Help files for more information on scheduling diagnostics.

1.11.1 Carrier Pressure Regulator Tests

This test compares the actual column pressure to the column pressure set point

using carrier gas. A failure of this test indicates that the carrier pressure is not

meeting or over exceeding the expected level of pressure.

1.11.2 Oven Temperature Test

This test compares the actual oven temperature to the oven temperature set point.

A failure of this test indicates that the oven is not maintaining the required

temperature.

1.11.3 Processor Control Test

This test contains three test areas: column 1 carrier pressure, column 2 carrier

pressure and oven temperature. In each area, the test measures the effort

required to maintain the required value. From those measurements, the test

develops a standard deviation and makes a comparison. The failure of any of

these comparisons indicates an erratic deviation exists, meaning the processor is

not able to control the function.
