3-30 | Model 931S / Model 932S UV Analyzers
Start-Up and Verication
This section describes equipment and controls on the analyzer system that
require adjustments and settings before, during, and after power-up. See
Figure 3-3 for the locations of analyzer equipment or controls that require
adjustments.
Powering Up the Analyzer
When powering up the analyzer, certain checks should be performed to
ensure the analyzer is operating properly. These checks are discussed in
the following power-up procedures.
Hazardous Locations
Before proceeding, test the area around the analyzer for explosive
gases and proceed only when the area is found to be safe.
Do not remove the cover of the Explosion-Proof Digital
Communications Port on the front of the Lower Enclosure, do not
connect a serial cable to the Communications Port, do not open the
Upper/Lower Enclosures, and do not power up/down the analyzer or
computer if there is an explosive gas atmosphere present.
Before operating the analyzer for the first time, following a pow-
er-up or reset, or after maintenance, you must manually block in
the sample gas flow.
Also, for verification and troubleshooting purposes during power up,
it will be necessary to work with the Upper/Lower Enclosures open.
Before powering up the analyzer, test the area for explosive gases. If an
explosive gas atmosphere is present, do not apply power to the analyz-
er or any alternate power sources that supply power to the analyzer
components. Proceed only when the area is found to be safe.
When the Electronics Enclosures are open, take appropriate precau-
tions to avoid electrical shock. Hazardous voltages are present inside.
Do not apply power to the analyzer if any of its flamepaths appear to
be scratched, dented, or worn. Applying power to an analyzer with a
damaged flamepath is dangerous and could result in serious injury
or death and/or serious damage to equipment. See “Examining and
Caring for the Flamepaths” in Chapter 6.
Replace parts immediately if damage or wear is apparent. Contact
AMETEK if there is any doubt about the integrity of any flamepath.
