3-30 | Model 900 ADA / Model 930 Sulfur Pit Analyzers
Powering Up the Analyzer
Before operating the analyzer for the first time, following a power-up or
reset, or after maintenance, you must manually backpurge the analyzer’s
sample system and adjust the sample gas flow rate. If start-up problems
occur, refer to “Start-Up Diagnostic Checklist” in this chapter.
For verification and troubleshooting purposes during power up, it
will be necessary to work with the analyzer’s covers and doors open.
Before powering up the analyzer, test the area for flammable gases.
If an explosive gas atmosphere is present, do not apply power to the
analyzer or any alternate power sources that supply power to the ana-
lyzer components. Proceed only when the area is found to be safe.
When the analyzer’s covers and doors are open, take appropriate
precautions to avoid electrical shock. Hazardous voltages are present
inside.
IMPORTANT
Performing analyzer start-up and verification procedures requires
working from the User Interface. Familiarize yourself with working
from the User Interface before working on the analyzer. See Chapter 4
for details on how to navigate from the User Interface.
