IMPORTANT
LASER SAFETY INSTRUCTIONS
The Raman Process Analyzer uses a Class IV Diode Laser with a maximum output of 1 Watt at a wavelength of 810 nm (invisible, near-infrared light). The light is transmitted through fiber optic cables to and
from the probe. The Raman Process Analyzer contains a Laser Safety Device that detects the return intensity of the laser light. If the return light diminishes below a certain level, the device reduces the laser
power to Class I. This safety feature reduces the chance of personnel injury from contact with the laser.
Take the following precautions when working around the Raman Process Analyzer:
Invisible laser light — avoid exposure to operating laser. A Class IV laser is used in
this analyzer. The laser has a maximum output of 1 Watt at a wavelength of
810 nm.
1. Only service this product if you have completed formal training in laser safety and
safe servicing techniques on this unit.
2. Never look at the probe tip when the probe is connected to the analyzer. Disconnect
the fiber optic cables before examining the probe.
3. Always clean the probe tip when removed from process. It may be possible for liquid droplets or particles to attach to the tip of the probe, allowing light “reflection”
to return to the Laser Safety Device. Use only appropriate material that will not
scratch or otherwise damage the probe tip.
4. Do not bring the probe tip in contact with any surfaces when removed from the process. Any “scattered” light returned by the probe may trigger the laser back to Class
IV.
5. All personnel working in the area of the laser must wear laser safety goggles (fullgoggle type with side shields). Goggles must have a minimum attenuation factor of
100,000 (optical density 5) for an 810 nm wavelength.

SECTION I. SYSTEM OVERVIEW
1-1. SCOPE OF MANUAL
This instruction bulletin covers installation, setup,
operation, troubleshooting, and maintenance of the
Raman Process Analyzer manufactured by Rosemount Analytical. The troubleshooting and service
procedures in this manual are limited to those that
can be performed by most equipment operators.
1-2. COMPONENTS CHECKLIST
(PACKAGE CONTENTS)
The Raman Process Analyzer system includes the
items listed in Figure 1-1. The SURE Calibration Kit
contains all the necessary components for quickly
calibrating the analyzer.
1-3. FUNCTIONAL EQUIPMENT DESCRIPTION
When properly configured, the analyzer detects and
measures the concentration of sample components
that inelastically scatter light. Access for the detection of the process components is accomplished with
one to four analyzer probes installed in or around the
process flow.
Functional components of the analyzer are shown in
the electronic diagram of Figure 1-2. The important
components of the diagram include the process
probes, the diode lasers, the laser safety device,
spectrograph, vortex cooler, CCD camera, and the
industrial computer. Brief descriptions of the analyzer component functions are provided in the following paragraphs.

The following are brief descriptions of analyzer component functions. A listing of components in the
analyzer cabinet is provided in Figure 1-3.
a. Diode Lasers and Probes. The analyzer uses
one or two diode lasers and up to four process
probes. Each diode laser generates a light beam.
The light beam is split in a 10/90 optic splitter.
Fiber optic cables transmit ten percent of the
beam to a diamond reference circuit and the remaining ninety percent to a 50/50 optic splitter.
A fiber optic cable from the diamond reference
transmits the reference beam to the spectrograph.
The ninety percent portion of the beam is evenly
split to provide excitation energy for two process
probes. Each beam is filtered at the probe to
eliminate stray radiation. The probe emits the
filtered laser beam into the process flow.
The process components inelastically scatter distinct wavelengths. Two return cables transmit
scattered light from the probe to the analyzer.
The unfiltered S cable transmits all scattered
light to the Laser Safety Device. The filtered R
cable transmits only a specific range of nearinfrared wavelengths to the spectrograph.
b. Laser Safety Device. To minimize operator
hazards, the laser safety device monitors the intensity of the scattered laser light from the process flow. If the safety device receives less than
an acceptably large part of the scattered light, it
reduces the laser power output from Class IV to
Class I.
The laser safety device continues to regulate the
output of the diode lasers at pulsed Class I power
levels until the device detects an acceptable
amount of scattered light from the process.
Low light scatter may indicate a broken fiber optic cable, a bad cable connection, or removal of
the probe from the process. Refer to the “Laser
Safety Instructions” in the front of this manual
for more information.
c. Vortex Cooler. The vortex cooler helps control
the temperature of the CCD (charge coupled device) camera and the cabinet interior. The main
function of the vortex cooler is to maintain the
ambient temperature near the camera at 30°C so
that the internal CCD chip temperature will remain at –30°C.
Incoming instrument air is dried, filtered, and
routed through a temperature-controlled air valve
to the vortex cooler. The vortex effect separates
the forced air into warm and cold air flows. The
chilled air is routed to the CCD camera.
As the cabinet air gets warmer, the air valve
opens a larger flow of forced air to the vortex
chamber, providing more cooling air to the camera. As the cabinet air cools, a proportional air
valve partly closes to slow the flow of cooling
air.
d. Spectrograph and CCD Camera. Filtered light
from the diamond reference and the R probe is
transmitted by fiber optic cable to the spectrograph. The spectrograph separates incoming light
into distinct wavelengths. Each wavelength of
light is sent to the CCD camera head where the
spectral image is decoded and electronically transferred to the CCD camera controller. The controller processes the spectral image into numerical
data. The data is sent to the industrial computer for
interpretation and display.
e. Industrial Computer. The industrial computer
converts data points into light intensity with respect to frequency. The histogram of each predicted component is displayed on the CRT. The
spectra are processed by the prediction’s algorithm in accordance with the calibration file.
Each application requires its own calibration file.
The output data is stored for further analysis.
f. User Interface. An interface device is required
to set up and operate the analyzer using the
MAIN and MAINCFG software programs. The
user interface device can be a remote computer
connected through a network modem, Ethernet,
RF antenna and laptop computer, or a monitor,
keyboard, and mouse connected at the analyzer
cabinet.
g. Analyzer Outputs. The available analyzer out-
puts are MODBUS and/or analog, 4 to 20 mA.
h. SURE Calibration Kit. The SURE calibration
kit is a light proof housing that secures the probe
tip above a fluorescent glass. The kit uses no
external light source or power source. When the
fluorescent glass and probe are properly assembled in the light-proof housing, the analyzer can
be calibrated using the MAINCFG software program.

SECTION II. INSTALLATION
2-2. TYPICAL INSTALLATION
Before starting to install this equipment,
read the “Safety instructions for the
wiring and installation of the laser” at
the front of this Instruction Bulletin.
Failure to follow the safety instructions
could result in serious injury, death, or
substantial property damage.
2-1. OVERVIEW
This section covers installation of the Rosemount
Raman Process Analyzer. Included are a typical installation, common requirements, what you need to
have on hand to start an installation, and the mechanical and electrical installation instructions. An
authorized Rosemount service representative must
complete the analyzer installation. You must complete the mechanical installation before calling the
service representative for final check-out and installation commissioning.
A typical system installation is shown in Figure 2-1.
When properly installed, the analyzer cabinet is securely mounted to a wall in the process control area.
The cabinet should not be mounted in the path of direct sunlight.
Process probes are installed in the process flow (usually a sampling flow). Up to four process probes may
be installed for each analyzer. The installed probes
should be adequately shielded from accidental impact, rainfall, and direct sunlight. Ready access for
probe removal, cleaning, and replacement is recommended.
Fiber optic cable lengths are per customer specification. Make sure the correct cables are selected for
each run. One inch or larger diameter conduits or cable troughs are recommended for shielding the fiber
optic cables. Pull boxes are needed when successive
cable bend angles exceed 180 degrees. Conduit ends
should point down to protect against water accumulation. Sharp conduit edges must be avoided and the
cables should be lubricated before pulling.

2-3. MECHANICAL INSTALLATION
a. Analyzer Cabinet.
Lift the cabinet with the upper brackets. Avoid
contact with the vortex cooler. Position and securely mount the cabinet using appropriate
screws and flat washers.
b. Raman Probe.
Never rest the cabinet standing up.
Damage to conduit fittings can occur.
The analyzer is housed in a NEMA-4X cabinet.
The NEMA-4X cabinet is suitable for wall
mounting in a Class I, Division II environment
when equipped with an ISA Type Z-Purge.
When lifting, the cabinet door must be closed
and latched. Make sure the mounting brackets
are installed and tight.
The analyzer cabinet weighs approximately 165
lbs (75 kg). Analyzer cabinet mounting dimensions are provided in Figure 2-2. Mark the position for cabinet hanger mounting on center with
wall studs or a securely mounted plywood backplate.

Each analyzer system includes up to four process
probes designed for mounting in a flow line or
tank. Install each process probe according to the
following instructions:
1.
Remove the protective covers from the
probe tip, Figure 2-3.
2. Install a bored through compression fitting
of compatible metallurgy in the process
line, tee, or process tank wall.
3.
Insert the probe to the desired depth in the
compression fitting.
4. If compatible with the process, apply a suit-
able sealant around the seal diameter of the
probe.
5. Tighten the compression fitting to secure
the probe. Do not over-tighten the fitting.

c. Fiber Optic Cable Conduits.
Fiber optic cables are precision optics
devices. Careless handling or installation of a fiber optic cable can result in
permanent cable damage.
1.
Install a 3/4 in. (19 mm) diameter minimum
conduit from the analyzer cabinet to each
process probe. The minimum radius for all
conduit bends is 10 in. (254 mm). For fiber
optic cable runs, it is not required to connect the conduit to the analyzer cabinet.

Carefully pull the cable through the conduit; pull enough cable to allow for cable
slack when connecting at the analyzer cabinet or probe.
6.
When using cable pull boxes, turn the
coiled cable over. Feed the pull tape to the
opposite side of the pull box. Wrap and tape
the cable to the pull tape and pull the free
end through the next section of conduit.
Repeat the cable pulling instructions as
needed to install all fiber optic cables.
