IMPORTANT NOTE:
Depending on ambient temperatures, reaching the desired oven temperature
could take up to an hour. During this time, you can follow the Startup Wizard as described in
section
and enter information as prompted.
6.4.2.3
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.
6.4.2.4
Stream test
This test measures various pressures for each available stream: Initial, Resting, Maximum, Holding,
Flowing and Ending.
Figure 6-20: Pressure test for streams
Stream
Pressure
Initial
< .5 psi
Resting
< .5 psi
Maximum
< 20 psi
Holding
± .2 psi for 6 seconds
Flowing
Between 5 and 20 psi
Ending
< .5 psi
Results from testing the various stream pressures at first-time installation helps to verify that the
Stream Sample Valves (SSVs) or the Sample Shut Off (SSO) valve are not leaking when closed. It
also verifies that the SSVs allow sample gas to pass through when opened.
IMPORTANT NOTE:
During startup, all streams are disabled. During the stream test, streams
with input pressure will be enabled, tested, and either passed or failed. Streams with no initial
input pressure will fail and are left disabled. Streams can always be enabled later if they will be
used (see section
6.5
Startup wizard
After starting PCCU32 and clicking the
Entry
icon, the analyzer’s Startup Wizard begins automatically
). The wizard initializes at first-time connection with a new analyzer or each time you
reconnect to the analyzer and have not completed the Startup Wizard. The wizard presents analyzer
configuration screens in the sequence required to place the analyzer in service.
