20. After pressing
ACK
in step 19, the
system performs a purge-from-span,
then automatically continues to step 21.
21. The screen indicates that the sample line
purge is in progress and displays the
time remaining to complete the process.
The screen displays the message:
PLEASE
WAIT
...
22. After 30 minutes, the screen will display
that the Ultra Trace sensor is being
connected. Afterwards, the system will
wait a maximum of 5 minutes for 30
PPM or less oxygen. If the oxygen
concentration is greater than 30 PPM,
the system will continue to step 23. If
the oxygen concentration is less than 30
PPM, the system automatically goes to
step 25.
23. If the oxygen content is greater than 30
PPM, the system performs another 15
minute sample line purge and returns to
the menu in step 22 to check again for
30 PPM or less.
24. Steps 22 and 23 will be repeated a
maximum of three times before the
system begins automatic shutdown. If
within 30 minutes the oxygen concen-
tration falls below 30 PPM, the system
will continue on to step 25.
NOTE: If the system shuts down due to high oxygen concentration, check
for leaks around gas connections. Check that gas concentrations
are not more than 30 PPM. Check that there is no back pressure
in the analyzer vent lines. Repeat Full Start.
