7. Enable analysis of the sample by taking the instrument out of the
suspend mode. The unit begins injecting and analyzing sample when
the instrument temperatures reach operating levels.
8. Allow the analyzer system to stabilize. Monitor the measured values on
the front panel for consistent analysis readings to determine when the
analyzer system has stabilized.
Startup After Short-
Term Shutdown
If initially starting the analyzer or if major service was performed, use the initial
start-up procedure detailed in the previous section,
Initial Start-Up .
When starting the analyzer after a short-term shutdown, perform the following:
1. Open the instrument and purge air and carrier air to the instrument.
Refer to the applications information, manuals, and drawings shipped
with the instrument, and adjust the pressure regulators to the
appropriate settings.
2. Apply power to the analyzer.
Note If the X-Purge option is installed, you must follow the instructions
include in Appendix F .

3. Allow the analyzer to warm up until the instrument stabilizes.
4. Adjust the flow rates.
5. Turn on sample to the instrument.
The analyzer includes an interlock system that prevents the injection valve from
operating until the pyrolyzer and oven temperatures reach the operating value.
Short-Term
Shutdown
Follow this procedure when temporarily shutting down the analyzer. To shut
down the analyzer for maintenance purposes or for a long-term shutdown, refer
to the following section,
Maintenance Shutdown .
1. Observe reported sulfur value.
2. Do not interrupt power, instrument air, carrier or auxiliary air, or open
oven doors until reported sulfur value is less than 0.5 ppm or reported
sulfur value has not changed by more than 2% for 15 minutes.
Note If possible, switch sample selection to nitrogen to sweep the system.
