Analyzer Troubleshooting and Maintenance
Generally, little maintenance is required to ensure the analyzer remains
operating at peak efficiency, other than that described in the “Removal
and Replacement of Major System Components.” This maintenance,
which includes parts that require scheduled replacement and cleaning, is
intended to ensure continued and proper operation of the analyzer.
Before performing maintenance on the analyzer, be sure to follow ap-
propriate actions and precautions to prepare the analyzer for service,
such as properly isolating the analyzer from the sample gas stream/
duct, backpurging the sample line (“Flush/Zero” mode), powering
down the analyzer (unless it is necessary to keep the analyzer operat-
ing), and opening the Electronics Enclosure.
For certain procedures, such as replacing source lamps, it is not required
to isolate the analyzer sampling system from the sample gas stream.
You must take precautions against ESD (electrostatic discharge) dam-
age while performing the following operations. Precautions include
using a wrist strap working on a grounded work surface, and storing
electronic assemblies in anti-static packaging.
Always disconnect power and/or external power sources to the ana-
lyzer before opening any covers or doors on the analyzer to check on
any components or to perform maintenance within the enclosures.
If it is necessary to open the analyzer’s covers or doors while the cir-
cuits are live, first monitor the area for flammable gases and proceed
only when the area is safe.
Cleaning/Replacing Parts in the Sampling System
To clean and/or replace parts in the analyzer sampling system:
1. Manually zero the analyzer (“Flush/Zero” mode), isolate the analyzer
sampling system from the sample gas stream, and power down the
analyzer as described in this chapter.
2. Continue with the procedures to disassemble, clean or replace parts,
and reassemble the appropriate sampling system components and all
associated sample system tubing.
