Introduction
SpectraSensors Overview
SpectraSensors, Inc. is a leading manufacturer of technologically advanced
electro-optic gas analyzers for the industrial process, gas distribution and
environmental monitoring markets. Headquartered in Houston, Texas,
SpectraSensors was incorporated in 1999 as a spin-off of the NASA/Caltech Jet
Propulsion Laboratory (JPL) for the purpose of commercializing space-proven
measurement technologies initially developed at JPL.
About the Gas Analyzers
The SS500e/SS2000e/SS3000e are tunable diode laser (TDL) absorption
spectrometers operating in the near- to short-wavelength infrared. Each
compact sensor consists of a TDL light source, sample cell and detector
specifically configured to enable high sensitivity measurement of a particular
component within the presences of other gas phase constituents in the stream.
The sensor is controlled by microprocessor-based electronics with embedded
software that incorporates advanced operational and data processing
algorithms.
Sample Conditioning System
A sample conditioning system is included with the system that has been
specifically designed to deliver an optimum sample stream that is
representative of the process systems stream at the time of sampling. Most
SS500e/SS2000e/SS3000e analyzer systems are configured for use at
extractive natural gas sampling stations.
Differences between the SS500e, SS2000e, and SS3000e
The SS500e and SS2000e are single-channel analyzers used predominantly for
measuring H2O or CO2 in pipeline natural gas. The SS2000e is a higher
resolution version of the SS500e (for performance specifications, see Table A–1
on page A–1, Table A–2 on page A–2, Table A–3 on page A–3 or Table A–4 on
page A–4). The SS3000e is a dual-channel version of the SS2000e and is
usually configured to measure H2O and/or CO2 in the same or separate pipeline
natural gas sample streams (for performance specifications, see Table A–5 on
page A–5). Refer to the following chart for an illustration of possible system
configurations for the SS3000e.

SS500e/SS2000e/SS3000e Gas Analyzer
How the Analyzers Work
The SS500e/SS2000e/SS3000e analyzers employ tunable diode laser
absorption spectroscopy (TDLAS) to detect the presence of trace substances in
process gases. Absorption spectroscopy is a widely used technique for sensitive
trace species detection. Because the measurement is made in the volume of
the gas, the response is much faster, more accurate and significantly more
reliable than traditional surface-based sensors that are subject to surface
contamination.
In its simplest form, a diode laser absorption spectrometer typically consists of
a sample cell with a mirror at one end, and a mirror or window at the opposite
end, through which the laser beam can pass. Refer to Figure 1–1. The laser
beam enters the cell and reflects off the mirror(s) making one or more trips
through the sample gas and eventually exiting the cell where the remaining
beam intensity is measured by a detector. With the SS500e/SS2000e/SS3000e
analyzers, sample gas flows continuously through the sample cell ensuring that
the sample is always representative of the flow in the main pipe.

Due to their inherent structure, the molecules in the sample gas each have
characteristic natural frequencies (or resonances). When the output of the
laser is tuned to one of those natural frequencies, the molecules with that
particular resonance will absorb energy from the incident beam. That is, as the
beam of incident intensity, I0(), passes through the sample, attenuation occurs
via absorption by the trace gas with absorption cross section (). According
to the Beer-Lambert absorption law, the intensity remaining, I(), as measured

of passes), is given by

(1)
where N represents the species concentration. Thus, the ratio of the absorption
measured when the laser is tuned on-resonance versus off-resonance is
directly proportional to the number of molecules of that particular species in
the beam path, or

Figure 1–2 shows the typical raw data from a laser absorption spectrometer
scan including the incident laser intensity, I0(), and the transmitted intensity,
I(), for a clean system and one with contaminated mirrors (shown to illustrate
the system’s relative insensitivity to mirror contamination). The positive slope
of raw data results from ramping the current to tune the laser, which not only
increases the wavelength with current, but also causes the corresponding
output power to increase. By normalizing the signal by the incident intensity,
any laser output fluctuations are canceled, and a typical, yet more pronounced,
absorption profile results. Refer to Figure 1–3.

Note that contamination of the mirrors results solely in lower overall signal.
However, by tuning the laser off-resonance as well as on-resonance and
normalizing the data, the technique self calibrates every scan resulting in
measurements that are unaffected by mirror contamination.
Wavelength Modulation Spectroscopy (WMS) Signal Detection
SpectraSensors takes the fundamental absorption spectroscopy concept a step
further by using a sophisticated signal detection technique called wavelength
modulation spectroscopy (WMS). When employing WMS, the laser drive
current is modulated with a kHz sine wave as the laser is rapidly tuned. A lockin amplifier is then used to detect the harmonic component of the signal that
is at twice the modulation frequency (2f), as shown in Figure 1–4. This phasesensitive detection enables the filtering of low-frequency noise caused by
turbulence in the sample gas, temperature and/or pressure fluctuations, lowfrequency noise in the laser beam or thermal noise in the detector.

With the resulting low-noise signal and use of fast post-processing algorithms,
reliable parts per million (ppm) or parts per billion (ppb) detection levels are
possible (depending on target and background species) at real-time response
rates (on the order of 1 second).
All SpectraSensors TDL gas analyzers employ a similar design and hardware
platform. Measuring different trace gases in various mixed hydrocarbon
background streams is accomplished by selecting a different optimum diode
laser wavelength between 700-3000nm, which provides the least amount of
sensitivity to background stream variations.
Getting Familiar with the Analyzer
SpectraSensors’ SS500e/SS2000e/SS3000e analyzers are typically comprised
of two main enclosures; the analyzer electronics and the sample conditioning
system (SCS), as shown in Figure 1–5. Refer to Appendix A for system
drawings. On the front panel of the analyzer, the keypad and LCD display serve
as the user interface to the analyzer. Internally, the control electronics drive the
laser, collect the signal, analyze the spectra and provide measurement output
signals.
Housed inside the SCS are the measurement cell and heater along with flow
devices to control flow and pressure for the measurement cell and the bypass
loop.

Power is connected to the analyzer from an external power source through the
top of the enclosure. The measurement cell along with flow devices to control
flow and pressure for the measurement cell and the bypass loop are mounted
inside the SCS enclosure. Refer to Chapter 3 for more information on the SCS.
Inside the SS500e/SS2000e/SS3000e analyzer electronics enclosure is the
electronics assembly. Refer to Figures 1–6 through 1-11 for a views of the AC
electronics assemblies and DC electronics assemblies.
The circled area in Figure 1–6 highlights the optional RS-232C to
RS-485 converter. For analyzers configured with an RS-232C
connection only, the converter is not installed on the electronic
assembly, which will use different cables for connections.

The SS500e/SS2000e/SS3000e analyzer is manufactured for wall or Unistrut®
(or equivalent) metal framing installations. Refer to the layout diagrams in
Appendix A for detailed mounting dimensions.
When mounting the analyzer, be sure not to position the
instrument so that it is difficult to operate adjacent devices. Allow
3 feet (1 m) of room in front of the analyzer and any switches.
It is critical to mount the analyzer so that the inlet and outlet lines
reach the inlet and outlet connections on the chassis while still
maintaining flexibility so that the sample lines are not under
excessive stress.

Installation
To mount the analyzer:
1. Select a suitable location to mount the analyzer. Choose a shaded
area or use an optional analyzer hood (or equivalent) to minimize
sun exposure.
SpectraSensors analyzers are designed for operation within the
specified ambient temperature range of –4 °F to 122 °F (–20 °C
to 50 °C). Intense sun exposure in some areas may cause the
analyzer temperature to exceed the maximum.
2. Locate the mounting holes on your unit.

ready for the electrical connections.
Connecting Electrical Power to the Analyzer
The analyzer will be configured for 100-240 VAC @ 50/60 Hz single phase input
or optionally 18–24 VDC input. Check the manufacturing data label or the
terminal block labels to determine the power input requirements. All work must
be performed by personnel qualified in electrical conduit installation. Conduit
seals should be used where appropriate in compliance with local regulations.
Hazardous voltage and risk of electric shock. Before
attaching the wiring to the analyzer, make sure all power to the
wires is off.
Careful consideration should be taken when grounding. Properly
ground the unit by connecting ground leads to the grounding
studs provided throughout the system that are labeled with the
ground symbol .
Depending on the analyzer configuration, the electrical wiring can typically be
connected to the analyzer through a conduit hub located at the upper right of
the electronics enclosure.

terminal block (TB2) located inside the analyzer electronics enclosure as shown
in Figure 1–6, Figure 1–7, Figure 1–8, Figure 1–10 or Figure 1–11. In addition,
two digital outputs per channel connected to SPDT relays are also provided.
The relay for the General Fault Alarm is configured to be fail-safe (or normally
energized) so the dry contact will open in the event of power loss or General
Fault Alarm. Thus, the cable for the General Fault Alarm should be wired to
the common and normally open (NO) terminals.
The standard configuration provides RS-232C output; however, optional
converters are available to provide RS-485 or Ethernet output. By default, the
4-20 mA current loop output is factory set to source current.

Changing the 4-20 mA Current Loop Mode
Changing the current loop mode may negate specific hazardous
area certifications. Contact your factory service representative for
details.
By default, the 4-20 mA current loop output is factory set to source current. In
some instances it may be necessary to change the 4-20 mA current loop output
in the field from source to sink. The work must be performed by personnel
qualified in electronics assembly.
To change a 4-20 mA board from source to sink:
1. Disconnect power to the analyzer and open the electronics enclosure
cover. Take care not to disturb the electrical assembly inside.
2. Locate the 4-20 mA board(s) on the electronics assembly panel in

6. Reconnect power to the analyzer. Confirm the 4 mA (min.) and
20 mA (max.) points (see “To scale the current loop signal” in
the Firmware Operator’s Manual).
7. Close and tighten the electronics enclosure cover.
Connecting the Gas Lines
Once you have verified that the analyzer is properly wired, you are ready to
connect the sample supply and sample return. Consult the layout and flow
diagrams in Appendix A for guidance. All work must be performed by
technicians qualified in instrument tubing. SpectraSensors recommends using
1/4” O.D x 0.035” wall thickness, seamless stainless steel tubing.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before installing
the SCS.
To connect the sample supply line:
1. First, confirm that the sample probe is correctly installed at the
process supply tap and that the sample probe isolation valve is
closed.
The process sample at the sample tap may be at a high pressure.
Use extreme caution when operating the sample probe isolation
valve and field-pressure reducing regulator.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
2. Also confirm that the field pressure reducing station is installed
properly at the sample probe and that the pressure regulator at the
field pressure reducing station is closed (adjustment knob turned
fully counter-clockwise).
3. Check that the relief valve vent line is properly installed from the
field pressure reducing station to the low pressure flare or
atmospheric vent connection.
4. Determine appropriate tubing route from the field pressure reducing
station to the SCS.

5. Run stainless steel tubing from the field pressure reducing station to
the sample supply port of the SCS. Bend tubing using industrial
grade benders, check tubing fit to ensure proper seating between
the tubing and fittings. Fully ream all tubing ends. Blow out the lines
for 10–15 seconds with clean, dry nitrogen or air prior to making the
connection.
6. Connect the inlet tube to the SCS using the 1/4” stainless steel
compression-type fitting provided.
7. Tighten all new fittings 1-1/4 turns with a wrench from finger tight.

3 - SAMPLE CONDITIONING SYSTEM
Personnel should have a thorough understanding of the operation
of the analyzer and the procedures presented here before
operating the sample conditioning system (SCS).
The process sample at the sample tap may be at a high pressure.
A pressure reducing regulator is located at the sample tap to
reduce the sample pressure and allow operation of the sample
conditioning system at a low pressure. Use extreme caution when
operating the sample probe isolation valve and field pressure
reducing regulator.
About the SCS
SS500e/SS2000e/SS3000e systems is typically ordered with an integral
Sample Conditioning System (SCS). Each SCS has been specifically designed
to deliver a sample stream to the analyzer that is representative of the process
stream at the time of sampling. To ensure the integrity of the sample stream
and its analysis, care must be taken to install and operate the SCS properly.
Therefore, any personnel intending to operate or service the analyzer and SCS
should have a thorough understanding of the process application and the
design of the analyzer and SCS.
Most problems experienced with sample systems tend to result from operating
the system differently than intended. In some cases, the actual process
conditions may be different than originally specified (e.g., flow rates, presence
of contaminants, particulates, or condensables that may only exist under upset
conditions). By understanding the application and the design of the system,
most issues can be avoided altogether or easily diagnosed and corrected to
ensure successful normal operation.
For SS500e/SS2000e/SS3000e Gas Analyzer systems, Natural Gas refers to
low pressure gas typically consisting of a mixture of methane (CH4) and
heavier hydrocarbons. A typical Natural Gas composition is listed in Table A-6
on page A–15.
The SS500e/SS2000e/SS3000e Gas Analyzer system has been
calibrated specifically for the type of background stream listed in
the calibration report. Significant deviations from the specified
stream composition may result in erroneous readings. If your
stream composition differs significantly from the composition
listed, your system may have undergone custom calibration. If
you are unsure, contact your factory sales representative.
Hardware Installation and Maintenance Manual
3–1
SS500e/SS2000e/SS3000e Gas Analyzer
Typical SCS Component Overview
All SpectraSensors TDL analyzers are designed for extractive sampling rather
than in situ applications. This allows for sample conditioning, filtration,
temperature, pressure and flow control to protect the optical components of
the system, and provides for ease of maintenance without shutting down the
process.
Some of the typical components used in the SCS will be described in this
section. The SCS for your analyzer may not use all of these components, and
may also include additional special devices not discussed here.
For questions regarding your SCS, please contact SpectraSensors’
Service department at 1-800-619-2861, 1-713-300-2700 option
#2 (International) or by email at service@spectrasensors.com.
Sample Probe
A sample probe is used to provide a representative sample of any process
stream. This sample can only be made if the stream is in a vapor phase. Mixed
liquid/vapor streams must be avoided, so the location of the sample probe is
critical in many processes.
Contact your SpectraSensors’ Sales representative to provide the
temperature, pressure and complete stream composition of the
process stream for advise and recommendations regarding
locating the sample point.
A representative sample of the process can only be taken away from the wall
of the process piping. Also, dirt and liquids tend to accumulate close to the
walls of the piping, especially near the bottom of horizontal runs of pipe.
Therefore, SpectraSensors recommends probes that fit well into the pipe.
These may be removable to protect the probe from pipeline “pigging”.
Sample Regulators at the Probe
The pressure of the sample gas is usually reduced at or very close to the
sample probe, sometimes in the probe itself, to reduce the sample transport
lag time to deliver the sample to the analyzer. A guard filter is typically used to
protect the regulator from larger particulates in the sample.
Refer to the following diagram that shows the interface of the probe and the
analyzer system. The analyzer system provided by SpectraSensors is
represented by the blue dashed outline. The probe and field pressure reducing
station may also be supplied by SpectraSensors, but is separate from the
analyzer system.

Sample Conditioning System Filters
A guard filter is typically installed at the inlet to the SCS with a fine element to
protect the flow controllers, flow meters and pressure regulators from fine
particulates.
A bypass filter with a fritted metal, glass fiber or polymetric membrane filter
may also be in place to remove larger quantities of particulates or entrained
liquids and mists. Some filters may fit with liquid knock-out traps to protect the
system from free liquids.
Accumulation of liquids in these filters, or a steady flow of liquid from a liquid
knock-out trap, should be investigated and corrected immediately as this is
generally an abnormal condition.
Sample Regulator Heaters
In most applications, the process sample is at high pressure. When the
pressure is reduced, the sample cools due to the Joule-Thompson effect.1 The
amount of cooling varies greatly depending on the application, but oftentimes
must be offset using a heated sample regulator to prevent condensation of
some sample components. Sample probe regulators can be electrically or
steam heated. Some probes have the pressure reducing valve parts inserted
into the process piping, so that the Joule-Thompson cooling is offset by
warming from the flowing sample. Note that for these probes to work correctly,
the process gas must be flowing anytime the sample is flowing or liquid
condensation may collect in the sample transport line, or even freeze up the
sample probe regulator. Refer to Appendix A for the proper regulator pressure
setting.
1
Named for James Prescott Joule and William Thomson, the Joules-Thompson effect
describes the increase or decrease in temperature that accompanies the expansion
of gas without production of work or transfer of heat. The cooling occurs because
work must be done to overcome the long-range attraction between the gas molecules as they move farther apart. (www.britannica.com)
Hardware Installation and Maintenance Manual
3–3
SS500e/SS2000e/SS3000e Gas Analyzer
Sample Transport Tubing
Sample transport tubing must be made of an appropriate material, which may
be coated, and of an appropriate diameter for the application. Many times the
sample transport tubing must be heat-traced to prevent sample condensation
or to prevent fluctuations in measurement due to changes in ambient
temperature. Refer to Appendix A for SpectraSensors’ recommended sample
transport tubing specifications.
Sample Bypass Flow Control
A sample bypass flow control valve and flowmeters are usually provided to
maintain a flow of fresh sample to the SCS even during system shut-down. The
flow control valve is typically a needle valve and should be closed very gently
and carefully if used to shut off flow completely to avoid damaging the valve.
If the bypass flowmeter has a glass tube, perform an occasional check for
evidence of liquid in the tube. If liquid is found in the bypass or sample cell
flowmeter tubes, investigate and correct immediately.
SCS Pressure Regulator
All SpectraSensors’ TDL cells are limited to a maximum 10 PSIG pressure. To
ensure that this pressure is not exceeded, a pressure regulator is provided
inside the sample system. Refer to Appendix A for the correct pressure setting
for this regulator.
Sample Cell Flow Controller
A sample cell flow controller is normally provided with the SCS. Typically a flow
control needle valve and flowmeter similar to the sample bypass are used, but
in some cases a differential flow controller is used. As with the bypass flow
control valve, if the flow control needle valve and flowmeter must be used for
sample shut-off, close the valve gently and carefully to avoid damage.
Validation Systems
Validation of the analyzer performance can be accomplished by comparison to
other analyzers, portable measurement devices, or by validation using a
cylinder standard.
Refer to Appendix A for details of the validation system used in your system.
Sample Return/Vent
Tunable diode laser spectroscopy is inherently sensitive to sample pressure in
the measurement cell, so the analyzers are calibrated for a range of sample
pressures. Most applications benefit from operation at low pressures instead of
high pressures. Sometimes the analyzer is designed to vent the sample to
atmosphere or an atmospheric pressure return system. Return to a flare or
3–4
4900002230 rev. A 8-18-14
Sample Conditioning System
other sample return must recognize the pressure limitations of the cell and also
the calibration of the analyzer.
SCS Heaters
Many analyzer systems have heated SCS enclosures. In many cases, this is
only to avoid condensation of sample components.
When starting up the heated SCS, follow the general guidelines below:
1. Energize power to the SCS and allow it to warm up to a level close
to the SCS sample temperature setpoint.
2. Start the sample flow and set to the specified flow rates.
3. Allow the system temperature to stabilize.
4. Energize power to the analyzer controller and ignore any error
messages that are seen on the display during the temperature
stabilization period.
5. Once the analyzer has been allowed to thermally stabilize, be sure
to enable Peak Tracking and any other software features as directed
in the chapter called “Operating the Analyzer” in the Firmware
Operator’s Manual.
Checking the SCS Installation
The integral SCS is factory set with the appropriate pressures, flow rates, and
enclosure temperature, as indicated in the system drawings (refer to
Appendix A). However, before operating the system for the first time, a careful
check of the installation of the entire SCS from the sample probe to the return
vent is recommended. SpectraSensors also recommends purging the transport
line to confirm there is no dust, particulates or liquids that were trapped during
installation.
To perform SCS installation checks:

Starting up the SCS
After the SCS installation has been thoroughly checked, you are ready to begin
preparing for initial SCS startup.
To prepare for SCS startup:
1. Confirm that all AC power switches for the analyzer and SCS are off.
2. If applicable, apply AC power to the electric heat-traced sample
transport tubing at the tracer control system.
Personnel should have a thorough understanding of the operation
of the heat tracer power supply and control system, if applicable,
before operating the SCS.
3. If applicable, confirm that the sample supply line electric heat tracer
temperature controller is set and that the sample supply line tracer
is heating to the appropriate temperature.
4. Confirm that the sample probe isolation valve is closed.
5. Confirm that the pressure regulator at the field pressure reducing
station is closed (adjustment knob turned fully counterclockwise).
6. Confirm that all sample system shut-off valves are closed.
3–6

Sample Conditioning System
7. Confirm that the sample bypass and analyzer flowmeter control
valves are gently closed (adjustment knob turned clockwise).
Do not overtighten the control valves or damage could occur.
To start up the field pressure reducing station:
The process sample at the sample tap may be at a high pressure.
Use extreme caution when operating the sample probe isolation
valve and field pressure reducing regulator.
1. Disconnect the sample transport tubing at the SCS and temporarily
run to a new, safe location (vent or flare).
2. Open the low pressure flare or atmospheric vent header shut-off
valve, if applicable, for the relief valve vent from the field pressure
reducing station.
The low pressure flare or atmospheric vent header shut-off valve
must be “car-sealed” open and tagged as a relief valve vent so
that this valve will not be closed unless the SCS is not in
operation.
3. Slowly open the sample probe process shut-off valve at the sample
supply tap.
4. Slowly open the pressure regulator at the field pressure reducing
station (adjustment knob turned clockwise) and set the pressure
regulator to the specified pressure. Refer to the system drawings in
Appendix A.
5. Blow sample through the sample transport tubing to flare or safe
vent to ensure that dirt or liquids are not in the sample tubing.
6. Reconnect the sample transport tubing and set the pressure
regulator to the specified pressure.
To start up the sample bypass stream on process sample:
1. Ensure the low pressure flare or atmospheric vent header shut-off
valve is opened for the bypass flow effluent from the SCS.
2. Open the sample supply shut-off valve.
3. Open the bypass flowmeter control valve to establish sample flow
from the sample probe and set the flowmeter control valve to the
specified value. Refer to the system drawings in Appendix A.
Hardware Installation and Maintenance Manual
3–7
SS500e/SS2000e/SS3000e Gas Analyzer
Do not open the cell flowmeter at this point.
4. Confirm that the sample supply pressure is set to the approximate
pressure specified under flowing conditions. Refer to the system
drawings in Appendix A.
Make sure that no liquid, solids, etc. are flowing through the
bypass by viewing the flowmeter. If substances are present, shut
down the system and purge the lines.
Although the exact supply pressure setpoint is not critical, the
pressure at the sample system should be within 5 PSIG of the
specified supply pressure setpoint. There may be a difference
between the pressure readings at the sample tap and inside the
SCS due to the pressure drop in the sample transport line under
flowing conditions. If the pressure at the SCS under flowing
conditions is not sufficiently close to the specified setpoint, it will
be necessary to readjust the pressure regulator setpoint at the
field pressure reducing station to provide the required supply
pressure with the specified sample bypass flow.
To start up the analyzer on process sample:
This procedure can be completed during the system warm-up
process. Refer to the system drawings in Appendix A for all
recommended settings.
1. Ensure the low pressure flare or atmospheric vent header shut-off
valve is opened for the sample flow effluent from the SCS.
2. Open the sample flowmeter control valve(s) to approximately the
specified flow for each measurement cell. Refer to the system
drawings in Appendix A.
3. If required, adjust each sample pressure regulator to the specified
setpoint for each measurement cell.
4. Adjust the sample flowmeter control valve(s) to the specified flows
for the measurement cells.
The adjustment setpoints of the analyzer flowmeters and
pressure regulators will be iterative and may require multiple
adjustments until the final setpoints are obtained.
3–8
4900002230 rev. A 8-18-14
Sample Conditioning System
The analyzer system has been designed for the sample flow rate
specified. A lower than specified sample flow rate may adversely
affect analyzer performance. If you are unable to attain the
specified sample flow rate, contact your factory sales
representative.
5. Confirm the sample flow and pressure setpoints and re-adjust the
control valve(s) and pressure regulator to the specified setpoints, if
necessary.
6. Confirm the sample bypass flow and re-adjust the control valve to
the specified setpoint, if necessary. The SCS is now operating with
the process sample.
7. Power up the analyzer according to the procedure given under
“Powering Up the Analyzer” in the Firmware Operator’s Manual.
8. After sufficient warm-up time, if applicable, confirm that the sample
system enclosure is heated to the specified temperature by
observing the temperature reading on the analyzer display.
Shutting Down the SCS
Situations may occur that require the shutdown of some or all of the SCS.
These circumstances may include short-term shutdown for repairs or parts
replacements, for example, or a long-term shutdown of the system for packing
and storing.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
The process sample at the sample tap is at a high pressure. A
pressure reducing regulator is located at the sample tap to reduce
the sample pressure and enable operation of the SCS at a low
pressure. Use extreme caution when operating the sample probe
isolation valve and field pressure reducing regulator.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
Hardware Installation and Maintenance Manual
3–9
SS500e/SS2000e/SS3000e Gas Analyzer
To isolate the measurement sample cell for short-term shutdown:
The analyzer can be isolated from the primary sample bypass section for shortterm shutdown or maintenance of the analyzer while allowing the sample
bypass flow to continue in a steady-state mode.
Due to the high pressure of the process sample, it is advisable to
allow the sample bypass flow to continue during short-term
isolation of the analyzer. Continuing sample bypass flow allows
the field pressure regulator to continue normal operation without
possible overpressure and activation of the relief valve in the
event the pressure regulator leaks when the downstream flow is
discontinued.
1. Close the sample flowmeter control valve(s) (adjustment knob
turned clockwise) for each measurement channel. Do not overtighten the control valve(s) or damage could occur.
2. Allow any residual gas to flow out of the measurement cells.
Never purge the analyzer with air or nitrogen while the system is
powered up.
3. Close the low pressure flare or atmospheric vent header shut-off
valve for the effluent from each measurement cell.
If the system will not be out of service for an extended period,
SpectraSensors advises that power remain applied to the sample
transport line electric tracer and the sample system enclosure
heater, if applicable.
To isolate the SCS for short-term shutdown:
The SCS can be isolated from the process sample tap for short-term shutdown
or maintenance of the SCS without requiring the shutdown of the field pressure
reducing station.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
3–10
4900002230 rev. A 8-18-14
Sample Conditioning System
Although the pressure reducing regulator at the process sample
tap is designed for “bubble-tight” shut off, this condition may not
occur after the system has been in operation for an extended
period. Isolation of the SCS from the field pressure regulator will
discontinue sample flow and may cause the pressure at the outlet
of the field pressure regulator to slowly increase if “bubble-tight”
shut off of the pressure regulator does not occur. The slow
pressure increase will continue until the pressure setpoint of the
relief valve is reached and the excess pressure is vented by the
relief valve. To prevent this, isolate the sample at the probe or
vent the sample to a safe location.
1. Isolate the analyzer from the bypass following the procedure under
“To isolate the measurement sample cell for short-term
shutdown” on page 3-10.
2. Close the sample supply shut-off valve to the SCS.
3. Allow the sample bypass to flow until all residual gas has dissipated
from the lines as indicated by no flow on the sample bypass
flowmeter.
4. Close the low pressure flare or atmospheric vent header shut-off
valve for the effluent from the sample bypass.
5. Turn off power to the analyzer.
If the system will not be out of service for an extended period,
SpectraSensors advises that power remain applied to the sample
transport line electric tracer and the sample system enclosure
heater, if applicable.
To isolate the process sample tap for long-term shutdown:
If the SCS is to be out of service for an extended period, the SCS must be
isolated at the process sample tap.
The process sample at the sample tap may be at a high pressure.
A pressure reducing regulator is located at the sample tap to
reduce the sample pressure and allow operation of the SCS at a
low pressure. Use extreme caution when operating the sample
probe isolation valve and field pressure reducing regulator.
The sample transport line must be vented to the low pressure
flare or atmospheric vent header through the bypass flowmeter to
avoid pressure surges. The procedure given in the following steps
can be followed regardless of whether or not the SCS has been
isolated from the process tap as described in the previous section.
Hardware Installation and Maintenance Manual
3–11
SS500e/SS2000e/SS3000e Gas Analyzer
All valves, regulators, switches, etc. should be operated in

shutdown” on page 3-10.
2. Confirm flow in the sample bypass flowmeter (the actual flow is not
critical).
3. Close the sample probe process shut-off valve at the sample supply
process tap.
4. Allow pressure in the field pressure reducing regulator to dissipate
until only a low residual pressure is indicated on the pressure gauge
at the field station.
5. Close the field pressure reducing regulator (adjustment knob turned
fully counterclockwise).
6. Close the low pressure flare or atmospheric vent header shut-off
valve for the relief valve vent from the field pressure regulator.
7. Close the sample supply shut-off valve to the SCS.
8. Leave the sample bypass flowmeter control valve open.
9. Close the low pressure flare or atmospheric vent header shut-off
valve for the effluent from the sample bypass.
10. Turn off power to the analyzer.
11. Turn off the AC power to the SCS heater and the sample tracer, if
applicable, at the power distribution panel.
Although power could be shut off to the sample supply electric
tracer, it is advisable to allow this line to remain heated unless the
SCS is to be out of service for an extended period or maintenance
is required on the line.
To purge the analyzer for shipment/relocation:
1. Refer to the procedure “To isolate the process sample tap for
long-term shutdown” on page 3-11.
2. Disconnect the sample tubing at the inlet to the analyzer. Refer to
drawings in Appendix A.
3. Connect clean, dry nitrogen to the sample inlet. Set to 30 PSIG.
4. Open the low pressure flare or atmospheric vent header shut-off
valve for the effluent from the sample bypass.
5. Allow the analyzer to purge for 20 minutes.
6. Shut off the nitrogen purge and disconnect.

Periodic SCS Maintenance
Due to the chemical properties of the process samples, care must
be taken to repair or replace components with proper materials of
construction. Maintenance personnel should have a thorough
knowledge and understanding of the chemical characteristics of
the process before performing maintenance on the SCS.
The status of the SCS should be checked regularly to confirm proper operation
(pressures, flows, etc.) and detect potential problems or failures before
damage occurs. If maintenance is required, isolate the part of the system to be
serviced by following the appropriate procedure under “Shutting Down the
SCS” on page 3-9.
All filter elements should be checked periodically for loading. Obstruction of a
filter element can be observed by a decreasing supply pressure or bypass flow.
If loading of a filter is observed, the filter should be cleaned and the filter
element replaced. Refer to “Replacing the Filter” on page B-15. After
observation for some time, a regular schedule can be determined for
replacement of filter elements.
No other regularly scheduled maintenance should be required for the system.
Preventive and Demand SCS Maintenance
Due to the chemical properties of the process samples, care must
be taken to repair or replace components with proper materials of
construction. Maintenance personnel should have a thorough
knowledge and understanding of the chemical characteristics of
the process before performing maintenance on the SCS.
Preventive and demand maintenance will be required when components and
parts deteriorate or fail as a result of continuous use. The performance of the
entire SCS and individual components should be monitored regularly so that
maintenance may be performed on a scheduled basis in order to prevent a
failure that could take the system out of operation.
The SCS is designed for convenient removal and replacement of component
parts. Complete spare components should always be available. In general, if a
problem or failure occurs, the complete part should be removed and replaced
to limit system down time. Some components may be repaired (replacement
of seats and seals, etc.) and then reused.
If the sample supply line does not appear to completely clear during normal
operation, it may be necessary to clean the sample transport line to remove
Hardware Installation and Maintenance Manual
3–13
SS500e/SS2000e/SS3000e Gas Analyzer
any liquid that may adhere to the wall of the tubing. The sample transport line
should be purged dry with air or nitrogen before the system is placed back in
operation.
The analyzer must be taken out of service during any cleaning of
the sample transport line.
If liquid makes it into the analyzer SCS, a filter element may become
obstructed leading to a decreasing supply pressure or bypass flow. If
obstruction of a filter is observed, the filter should be cleaned and the filter
element replaced.
Regular SCS Status Check
1. Open the SCS door.
2. Read and record the flowmeter settings while the gas is flowing.
3. Close the SCS door.
Do not leave the SCS door open any longer than absolutely
necessary. SpectraSensors recommends no more than 60
seconds.
4. Compare the current readings with the past readings to determine
any variations. Reading levels should remain consistent.
5. If reading levels decrease, check the filters.
To check filters:
1. Shut down the system following the procedure in “Shutting Down
the SCS” on page 3-9.
2. Inspect, repair or replace the filter as required. Refer to “Replacing
the Filter” on page B-15.
For additional information, contact SpectraSensors’ Technical
Service Group at 1-800-619-2861.
3. Restart the system following the procedure in “Starting up the
SCS” on page 3-6.

Appendix B: Troubleshooting
This chapter presents recommendations and solutions to issues that may be
experienced during analyzer operation. If the problem being encountered is not
referred to in this chapter, refer to “Service Contact” on page B-22.
Class 3B invisible laser radiation possible when open. Avoid
exposure to the beam. Never open the sample cell unless directed
to do so by a service representative and the analyzer power is
turned off.
The optical head has a seal and “WARNING” sticker to prevent
inadvertent tampering with the device. Do not attempt to
compromise the seal of the optical head assembly. Doing so will
result in loss of device sensitivity and inaccurate measurement
data. Repairs can then only be performed by the factory and are
not covered under warranty.
Gas Leaks
Probably the most common cause of erroneous measurements is outside air
leaking into the sample supply line. It is recommended the supply lines be
periodically leak tested, especially if the analyzer supply lines have been
disconnected and reconnected due to relocation, replacement or returned to
the factory for service.
Do not use plastic tubing of any kind for sample lines. Plastic
tubing is permeable to moisture and other substances which can
contaminate the sample stream. SpectraSensors recommends
using 1/4” O.D. x 0.035” wall thickness, seamless stainless steel
tubing.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
Contamination
Contamination and long exposure to high humidity are valid reasons for
periodically cleaning the gas sampling lines. Contamination in the gas sampling
lines can potentially find its way to the sample cell and deposit on the optics or
interfere with the measurement in some other way. Although the analyzer is
designed to withstand some contamination, it is recommended to always keep
the sampling lines as free from contamination as possible.
Hardware Installation and Maintenance Manual
B–1
SS500e/SS2000e/SS3000e Gas Analyzers
To keep the sampling lines clean:
1. Make sure that a filter or membrane separator is installed ahead of
the analyzer and is operating normally. Replace the membrane or
filter, if necessary (refer to “Replacing the Membrane
Separators” on page B-15 or “Replacing the Filter” on page
B-15).
If liquid enters the cell and accumulates on the internal optics, a
Laser Power too Low fault will result.
2. If mirror contamination is suspected, refer to “Cleaning the
Mirrors” below.
3. Turn off the sample valve at the tap in accordance with site lock-out,
tag-out rules.
4. Disconnect the gas sampling line from the sample supply port of the
analyzer.
5. Wash the sampling line with a suitable solvent and blow dry with
mild pressure from a dry air or nitrogen source.
6. Once the sampling line is completely free of solvent, reconnect the
gas sampling line to the sample supply port of the analyzer.
7. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
Cleaning the Mirrors
If contamination makes its way into the cell and accumulates on the internal
optics, a Power Fail fault will result. If mirror contamination is suspected,
please consult with your factory sales representative before attempting to
clean or replace the mirror(s). If advised to do so, use the following procedure.
Do not attempt to clean the cell mirror until you have consulted
with your factory service representative and have been advised to
do so.
The sample cell assembly contains a low-power, 10 mW MAX, CW
Class 3b invisible laser with a wavelength between 750-3000 nm.
Never open the sample cell flanges or the optical assembly unless
the power is turned off.
B–2
4900002230 rev. A 8-18-14
Troubleshooting
Always handle the optical assembly by the edge of the mount.
Never touch the coated surfaces of the mirror.

Determining the type of cell mirror
Measurement cells will come equipped with either a glass or stainless steel
mirror. Before determining whether to clean or replace the mirror, identify the
type of measurement cell being used in the analyzer. There are two types of
measurement cells used with the SS500e/SS2000e/SS3000e; 0.1-m, 0.8-m.
Refer to Figure B–1.

Measurement cell types
The stainless steel mirrors are identified with either an “X” engraved on the
outside bottom of the mirror or a groove around the rim of the mirror. Glass
mirrors have no external markings. To determine the type of mirror being used
for the system cell:
1. Feel at the bottom of the cell for the engraved “X” marking. Refer to
Figure B–2 below.

B–4
4900002230 rev. A 8-18-14
Troubleshooting
Do not attempt to replace a glass mirror with a stainless steel
mirror or system calibration may be adversely affected.
To clean the mirror, refer to the instructions “To clean the mirror” on page
B-5. To replace a stainless steel mirror, refer to the instructions for “To replace
the stainless steel mirror” on page B-6.
To clean the mirror:
1. Power down the analyzer following the procedure outlined in the
section called “Powering Down the Analyzer” in the Firmware
Operator’s Manual.
2. Isolate the analyzer from the sample bypass flow by shutting off the
appropriate valve(s) and/or pressure regulator. Follow the procedure
outlined in “Isolating the Measurement Cell for Short-term
Shutdown” in the Firmware Operator’s Manual.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
3. If possible, purge the measurement cell with nitrogen for 10
minutes.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
4. Carefully mark the orientation of the mirror assembly on the cell
body.
Careful marking of the mirror orientation is critical to restoring
system performance upon reassembly after cleaning.
5. Gently remove the mirror assembly from the cell by removing the
socket-head cap screws and set on a clean, stable and flat surface.
The sample cell assembly contains a low-power, 10 mW MAX, CW
Class 3b invisible laser with a wavelength between 750-3000 nm.
Never open the sample cell flanges or the optical assembly unless
the power is turned off.
Hardware Installation and Maintenance Manual
B–5
SS500e/SS2000e/SS3000e Gas Analyzers
Always handle the optical assembly by the edge of the mount.
Never touch the coated surfaces of the mirror.
6. Look inside the sample cell at the top mirror using a flashlight to
ensure that there is no contamination on the top mirror.
SpectraSensors does not recommend cleaning the top mirror. If
the top mirror is visibly contaminated, contact your factory
service representative.
7. Remove dust and other large particles of debris using a bulb blower
or dry compressed air/nitrogen. Pressurized gas duster products are
not recommended as the propellent may deposit liquid droplets onto
the optic surface.
8. Put on clean acetone-impenetrable gloves.
9. Double fold a clean sheet of lens cleaning cloth and clamp near and
along the fold with the hemostats or fingers to form a “brush.”
10. Place a few drops of Isopropyl alcohol onto the mirror and rotate the
mirror to spread the liquid evenly across the mirror surface.
11. With gentle, uniform pressure, wipe the mirror from one edge to the
other with the cleaning cloth only once and only in one direction to
remove the contamination. Discard the cloth.
Never rub an optical surface, especially with dry tissues, as this
can mar or scratch the coated surface.
12. Repeat with a clean sheet of lens cleaning cloth to remove the streak
left by the first wipe. Repeat, if necessary, until there is no visible
contamination on the mirror.
13. Carefully replace the mirror assembly onto the cell in the same
orientation as previously marked making sure the O-ring is properly
seated.
14. Tighten the socket-head cap screws evenly with a torque wrench to
13 in-lbs.
To replace the stainless steel mirror:
If your system has been configured with a stainless steel mirror in the 0.1-m
or 0.8-m measurement cell, use the following instructions for replacing the
mirror.
B–6
4900002230 rev. A 8-18-14
Troubleshooting
If stainless steel mirrors are replacing another version of mirror in
the field, such as glass, the analyzer may need to be returned to
the factory for re-calibration to ensure optimal cell function. Refer
to “Service Contact” on page B-22.

Excessive Sampling Gas Temperatures and
Pressures
The embedded software is designed to produce accurate measurements only
within the allowable cell operating range (refer to the system drawings in
Appendix A and/or calibration report).
The cell temperature operating range for analyzers that are
equipped with heated enclosures is equal to the enclosure
temperature setpoint ±5 °C.
Pressures and temperatures outside this range will trigger a Pressure Low
Alarm, Pressure High Alarm, Temp Low Alarm, or Temp High Alarm
fault.
If the pressure, temperature, or any other readings on the LCD
appear suspect, they should be checked against the specifications
(refer to the system drawings in Appendix A and/or calibration
report).
Confirming the Relief Valve Setting
Confirm that the relief valve at the field pressure reducing station has been set
to the specified setpoint. Refer to the analyzer drawings for the required
settings.
1. Remove the relief valve from the pressure reducing regulator and
connect to an adjustable pressure source.
Refer to the manufacturer’s instructions for details related to
setting the relief valve.

Peak Tracking Reset Procedure
The analyzer’s software is equipped with a peak tracking function that keeps
the laser scan centered on the absorption peak. Under some circumstances,
the peak tracking function can get lost and lock onto the wrong peak. If the
difference between PkDf and PkDl is more than 4, or Track Fail Error is
displayed, the peak tracking function should be reset. Refer to the Firmware
Operator’s Manual for this analyzer for instruction.
Electrical Noise
High levels of electrical noise can interfere with laser operation and cause it to
become unstable. Always connect the analyzer to a properly grounded power
source.
