2.11 NGC Start-Up Diagnostics

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:
•
•
•
•
These start-up tests may also be performed on a regular schedule. See the PCCU
Help files for more information on scheduling diagnostics.

2.11.1 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.

2.11.2 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.

2.11.3 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 that an erratic deviation exists, meaning the
processor is not able to control the function.

2.11.4 Stream Test

This test measures various pressures for each available stream. Failure of a
stream indicates an inability to meet certain criteria.
During the initial start-up, all streams are disabled. During the stream test, streams
with input pressure are re-enabled, tested and either passed or failed. Streams
with no initial input pressure fail.
