Totalflow has performed extensive testing on each
NGC8200 prior to shipment, and each unit is factory-
calibrated using our standard calibration blend.
During the stream test, streams with no gas pressure will
fail, and they will be disabled in the stream sequence. To
enable these streams, click Stream Setup on the Analyzer
Operation screen.
6.2.1 Status
The following description status and definitions are standard for all start-up
diagnostics. Additionally, each test group will have status results that will narrow
down the possibilities for troubleshooting.
Status Description
Idle No tests are running.
In Progress Test(s) are in progress.
Passed Basic and/or additional tests, if required, passed.
Failed
The basic test failed plus additional more in-depth
tests were run and also failed.
Aborted
Tests were aborted by the user using the Abort
command.
6.2.2 Carrier Pressure Regulator Test
If Col 1 or Col 2 carrier pressure test failed, the following procedure will step the
user through the troubleshooting process. On occasion, these instructions may
detour to other procedures, and, when complete, the user should return to these
procedures to continue.
6.2.2.1 Description
These alarms are indicative of low carrier pressure. The causes range from a
closed carrier bottle regulator to a blockage inside the GC module.
6.2.2.2 Status
The following descriptive status and definitions are applicable for only the carrier
pressure regulator test and are in addition to those defined for all start-up
diagnostics.
Status Description
Low Reg Pressure
Pressure is too low to continue the test. Possible
causes are the carrier bottle is low, the regulator on the
carrier bottle needs to be turned up to 90 PSIG, carrier
line from the bottle to the NGC is plugged, etc.
Flow Blocked
A blockage was sensed during one of the tests. The
flow test was run in an attempt to dislodge the blockage
but was not successful. See flow test below.
Pressure Reg Test
This is an additional test that is in progress because the
basic test failed. A different status will be displayed
after the test has finished.
