E. Electrical power
F. Measurement data
G. Control center
Emerson has designed the analyzer for industrial process applications
requiring ATEX Zone 1 hazardous area certification; the analyzer has an Ex d
flameproof enclosure. It contains an optical system with multiple lasers and
a series of optical components that provide an optical path, a heated multipass analysis cell, and sample and outlet ports that can be connected to a
gas handling system and control and analysis electronics. The number of
lasers installed depends upon customer requirements. The complete system
operates Vac from a 110/240 Vac 50/60 Hz supply.
The analyzer uses mid-infrared optical absorption spectroscopy to measure
gas concentrations. The light sources are lasers, which are operated to
produce wavelength sweeps that cover the absorption lines of the gases.
The light from each laser is routed through an optical path to the analysis
cell, which provides measurement of low concentrations of the subject
gases. An external sample handling system conditions the sample gas and
draws it through the analysis cell. The light exits the multi-pass analysis cell
and is directed to a receiver in the analyzer. The variation in the intensity of
light in the vicinity of the absorption lines is measured, and the
concentration is determined using a comprehensive spectral fitting routine.

1.5.1Optical description
The laser modules are located in the core of the analyzer. Each laser module
produces a separate light beam, and these beams are combined linearly as
the modules are aligned in the system. The combined beams are closely
coupled, parallel, and coaxial about a virtual line. The laser light beams pass
through an optical steering assembly, which directs the laser beam through
the sample cell.
The sample cell contains a set of mirrors to create a path through the sample
gas that is between 0.7 ft. (0.2 m) and 49.2 ft. (15 m) through multiple
reflections along the length of the cell. The laser beams exit the cell at the
opposite end from where they entered and are directed using a second
optical block to a receiver.
By measuring and analyzing the light detected by the receiver unit, it is
possible to accurately determine the concentrations of the target molecules
within the gas sample cell.

corrosion, gas leaks, or overheating. Report anything found to the
hazardous area Ex maintenance organization.
2. Make sure that the analyzer has been correctly installed.
See Install.
3. Make sure that the enclosure is closed and all bolts are correctly
torqued.
If the enclosure cannot be closed and locked, report it to the
maintenance organization and do not proceed further until the door
has been repaired.
4. Make sure that the gas handling system is turned OFF.
5. Make sure that the external circuit breaker is set to OFF.
6. Visually examine the gas ports to make sure that the sample supply
line and the sample return line are correctly attached to the analyzer.
7. Visually check that the electrical connections have been made to the
instrument.
8. Set the main circuit breaker to ON, which applies main power to the
instrument.
The analyzer begins its automatic startup. The control PC that forms
part of the instrument is configured to automatically load the
necessary gas sensor software and configuration files. The startup
sequence commences automatically under software control.
At the end of the startup procedure, the gas measurements initially appear
as 0.00 ppm until the first readings are taken. After a few seconds, the
initial gas concentrations will be displayed.

4.1Introduction
This chapter describes the controls, displays, and indicators on the
Rosemount CT5800 and how to use the display controller located on the
front panel of the instrument.
NOTICE
The gases shown in the screenshots and the measurements may be different
from those shown in your particular analyzer. They indicate the functionality
of the software, which is the same regardless of the gases or gas
concentrations being measured.
4.2Normal operation
The analyzer is designed for long term continuous operation, and therefore
its normal state is to be switched on and performing gas measurements. The
analyzer is usually only switched off for maintenance.
