Pgc2000 With Flame Photometric Detector; Air Purge Systems - ABB PGC2000 Operation And Service Manual

Each analyzer has a temperature code (T-Rating) listed on the nameplate. This T-Rating indicates
the temperature classification of the area in which the analyzer has been designed to operate. T-
Ratings and area classifications for analyzer locations are determined and supplied by the customer.
A package titled "Important Papers" comes with the analyzer. Included in this package are data
sheets and installation drawings needed to support installation and setup of the analyzer. This
manual refers to these data sheets and drawings as the "Data Package."

PGC2000 WITH FLAME PHOTOMETRIC DETECTOR

When the analyzer has a flame photometric detector (FPD), a panel attached to the left side of the
analyzer contains the detector, the detector amplifier, and the high-voltage transformer that provides
the spark to ignite the FPD (see Figure 1-2).

AIR PURGE SYSTEMS

If the analyzer will be in a Class I hazardous location, an air purging system must be installed to
reduce the risk of explosion. Class I locations are those in which flammable gases or vapors are or
may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.
The GCC purge is part of the basic design of the analyzer and must remain functional under all
operational circumstances.
