1 Safety
1.1 General warnings and cautions
If the Laser 3 Plus is used in a manner not specified within this
manual, the protection provided by the equipment may be impaired.
Failure to observe the requirements of the manual may result in the
user being held responsible for the consequences and may
invalidate any warranty.
Before you attempt to install, commission or use the Laser 3 Plus,
read this manual carefully.
Do not attempt to install, commission, maintain or use the Laser 3
Plus unless you are trained and competent.
The Laser 3 Plus does not include any user-serviceable parts.
The Laser 3 Plus does not include any user replaceable fuses.
Do not use the Laser 3 Plus as Personal Protective Equipment
(PPE).
If you do not install and use the Laser 3 Plus in accordance with the
instructions in this manual, you may risk exposure to hazardous
laser radiation.
The Laser 3 Plus may be attached to equipment that is hot. Always
wear the appropriate PPE to minimize the risk of burns.
Where there is a risk associated with the release of potentially
harmful gases into the operating environment, always use suitable
monitoring equipment.
The gases included in the process being monitored may be toxic,
asphyxiant or flammable.
Before you use the Laser 3 Plus, make sure that all connections are
leak-free at full operating pressure to prevent exposure of
personnel and the environment to the hazardous gases.
The analyser may fail if it is used with sample streams that contain
substances not compatible with those listed in Section 2.8.
Make sure that you install the instrument to conform to all relevant
safety requirements, National Electrical Code and any local
regulations. The installation must be safe for any extremes of
11

07931001B revision 2
operating conditions which may occur in the operating environment
of the Laser 3 Plus.
Do not install the analyser on a surface which is subject to high
levels of vibration or sudden jolts. Sample measurements may not
be accurate and the analyser may be damaged.
1.2 Laser safety
CLASS 3R LASER PRODUCT.
LASER RADIATION. The Laser 3 Plus is a Class 3R laser product. The
laser light is not visible. Do not look into the laser beam. Avoid direct eye
contact with the laser radiation.
The transmitter and receiver units both have a Laser On indicator. This is
ON when the transmitter emits laser radiation from the optical window.

LASER RADIATION. Changes to settings or performance of procedures
other than those specified in this manual may result in hazardous
radiation exposure.
1.3 Certification
1.3.1 Hazardous area installations
Do not modify the unit, either mechanically or electrically, or the
certification of the instrument will be invalidated and it may not operate
safely.

Make sure that the operating environment is within the limits specified in
the product data (section 2.6.5).
Do not install the Laser 3 Plus in a high-velocity dust-laden atmosphere.
Do not open the enclosure if an explosive atmosphere is present.
Do not open the enclosure if the Laser 3 Plus is energized.
It is a condition of certification that the unit must be installed following
the appropriate national or international legislation or codes of practice.
In particular, you must make sure that the correct glands are fitted to
cable entries and that you do not compromise the weatherproofing of the
enclosure.
All of the analyser electrical connections are considered to be incendive
and therefore must only be connected to safe area equipment.
The equipment is incapable of passing the dielectric strength test
prescribed by the standards, and so this must be taken into account
during installation by using an SELV power source with a prospective
short circuit current not exceeding 40A.
1.3.2 Hazardous area variants
Do not use hazardous area variants with a process atmosphere that
requires EPL Ga. (e.g. Zone 0). If they are used within this process
atmosphere, the hazardous area certification may be invalidated.
Do not use hazardous area variants for oxygen enriched flammable
samples; that is gases over 21% O2. If they are used with gases
containing over 21% O2 the hazardous area certification may be
invalidated.
Hazardous area variants are certified for use with a flammable process
atmosphere at a pressure of 0.8 to 1.1 bar absolute (11.6 to 15.95 psi). If
used with a flammable process atmosphere beyond these limits, the
hazardous area certification may be invalidated.

2 Introduction
2.1 Product description
The Laser 3 Plus is an advanced gas analyser. It comprises a transmitter unit (TU) and
a receiver unit (RU), with an optional AC to DC power supply, ancillary equipment and
sample cell.
The laser radiation detected by a photo-detector is amplified and transferred to the
transmitter unit through a multi-core cable which connects the receiver and transmitter
electronics. The same cable transfers the required power from the TU to the RU.
Connectors at each end of the cable, and a removable gland plate, allow removal of
the TU and RU for calibration or maintenance.
Flange mounts and window purge assemblies are provided to mount the transmitter
and receiver to the process flanges. Quick-connect connections between the
instrument and mounting assembly allows easy removal of the transmitter and receiver
for calibration or maintenance.
For continuous in-situ applications, the Laser 3 Plus is installed directly across stacks,
ducts and reactors typically employing path lengths of 0.1 to 25m (3.94" - 82ft.).

4.2 Configure mA inputs
mA inputs are provided to allow the analyser to make measurement corrections when
there are external influences in the process such as sample gas temperature and
pressure.
The analyser can be supplied with an ‘Options PCB’ that provides two mA inputs for
peripheral measurement devices.
The mA input provides a constantly updated input to the analyser, in which the current
represents the value being measured by the peripheral device.

4.2.4 Explanation summary of the mA Input parameter settings
55
Parameter
Function
Physical property
The option selected determines the mA input
measurement type
Units
Assigns a measurement unit to the mA input. The
options presented on the screen will be dependent on
the physical property selected
Label
Assign an appropriate name to the mA input.
For example: ‘Temp’ for temperature, ‘Press’ for
pressure
Current 1 (low set)
This is the minimum measurement current for the
connected mA input device. Typically 0 – 4 mA
Current 2 (high set)
This is the highest measurement current for the
connected mA input device. Typically 20 mA
Measurement 1 (low)
Corresponding minimum measurement at Current 1
(low set) for the connected mA Input device
Measurement 2 (high)
Corresponding maximum measurement at Current 2
(high set) for the connected mA Input device
Under range
A tolerance value set below the current 1 (low set)
value. It sets the lowest input current during normal
operation
Over range
A tolerance value set above the current 2 (high set)
value. It sets the highest input current during normal
operation
Out of range state
This is the action you want the analyser to take when
the mA input values fall outside of the under range /
over range values
Filter time
Filters the input over a given time period. This is used
to ‘smooth-out’ the measurement values.
Reset threshold
Sets the threshold where you want the filter to
‘collapse’ and revert to a non-filtered state until the
change in reading falls back below the reset threshold
(currently selected units apply)

4.3 Process environment settings “physical set up”
The analyser needs to be configured to suit the process environment.
Configuration includes setting the laser path length, process pressure and process
temperature etc.
Note:
When the laser measurement signals have been optimised and the
process environment set up has been completed Servomex recommend
saving the configuration. See section 3.10.1
The physical parameters that must be set up are illustrated in the following sequential

4.3.1 Pressure source selection
3 options are available for each segment
Option 1: External
External should be selected when the required pressure source is a mA input device.
Option 2: User defined 0-4
User defined fixed pressures can be entered and saved, to be used either with stable
process conditions or when purge compensation is enabled.
Note:
User defined pressures should only be used when the pressure of the
measured gas is constant and stable. Incorrect use will result in reported
concentration errors if the purge gas or process gas pressure changes.
Option 3: Transmitter enclosure
The analyser is fitted with a pressure transducer mounted on the main process PCB
inside the transmitter enclosure. The transducer will measure the pressure inside the
enclosure. An offset can be applied to correct for differences in measurement gas
pressure and the internal enclosure pressure.
Note:
If an environmental purge is fitted, the enclosure pressure may be higher than
the atmospheric pressure, and an addition to the calculated offset should be
applied.
4.3.2 Temp source selection
4 options are available for each segment
Option 1: External
External should be selected when the required temperature source is a mA input
device.
Option 2: User defined 0-4
User defined fixed temperature can be entered and saved to be used either with stable
process conditions or when purge compensation is enabled.
Note:
User defined temperatures should only be used when the temperature of the
purge gas is constant. Changes in measured gas temperature will result in reported
concentration errors.
Option 3: Transmitter Enclosure
The transmitter enclosure is fitted with a thermistor mounted on the main process PCB.
The thermistor will measure the temperature inside the enclosure.
Option 4: Receiver enclosure
The receiver enclosure is fitted with a thermistor mounted on the main process PCB.
The thermistor will measure the temperature inside the enclosure.
57
© Servomex Group Limited. 2017
07931001B revision 2
An offset can be applied to correct for differences in measurement gas temperature
and the internal enclosure temperature.
Hint:
Note:
Note:
Under normal operating conditions the enclosure internal temperature is
approximately 15 to 20°C above ambient.
If an environmental purge is fitted, the value reported may be higher or lower
than the ambient temperature dependant on the purge gas temperature, and
an adjustment to the calculated offset should be applied.
When the physical or user settings have been completed Servomex
recommend saving the configuration. See section 3.10.1
4.3.3 Path length and purge compensation
When purge compensation is “disabled” the measurement path length is defined as the
total distance between laser diode and receiver photodiode minus the total purged
length; the examples shown describe 2 common installation configurations.
Note:
Purge compensation “disabled” should, in general, only be used when using
a purge gas that does not contain any target gas .

The example sequence below show settings options for 1 of the additional 4 segments,
the sequence needs to be complete for all segments. A concentration level is required
for all 4 segments. E.g. if purging with instrument air and measuring O2 the
concentration in purged segments will be that of the instrument air.

4.4 Configure mA outputs
4.4.1 mA outputs
There is 1 mA output provided on the standard analyser configuration. An additional
mA output is available if the analyser is supplied with an ‘options PCB’. Supervisor
level is required to configure mA output.
Each output can be assigned to one of 4 measurement properties or the transmission.
The mA output provides a constantly updated output, in which the current represents
the value of the measurement.
The analyser allows you to specify two separate range configurations for the mA
outputs, range 1 and range 2.
The mA output can be selected as:
0 – 20 mA
0 mA represents the lowest sample measurement and 20 mA
represents the highest sample measurement in the range
specified
4 – 20 mA
4 mA represents the lowest sample measurement and 20 mA
represents the highest sample measurement in the range
specified
You can also specify how the mA output operates during calibration, a fault condition
and under-range conditions.
Note:
07931001B revision 2
For applications where the fault relay is not being used, configure the mA
output to 4 -20 mA and jam low (default setting) for safety and to prevent any
analyser faults going undiagnosed. This is the safest mode of operation.

monitored through the mA output
For example, with an under range setting of 3.8 mA, the mA output can be
less than 4 mA (indicating a zero gas concentration), down to a minimum of
3.8 mA, where an output between 3.8 mA and 4 mA indicates a negative gas

4.5.5 Hysteresis levels
The hysteresis level associated with a measurement alarm determines when an
activated condition is deactivated. This depends on the alarm mode:
71

07931001B revision 2
Alarm mode
Hysteresis effect
Low alarm
Once a low alarm condition is activated, the alarm condition is not
deactivated until a sample measurement is above:
Alarm level + hysteresis level
High alarm
Once a high alarm condition is activated, the alarm condition is not
deactivated until a sample measurement is below:
Alarm level - hysteresis level
Example: If a low alarm has an alarm level of 18% and a hysteresis level of 1%, the
alarm is activated when a sample measurement is <18% and the alarm is not
deactivated until a sample measurement is >19%.
4.5.5.1 To set alarm level and hysteresis
Figure 4-25: Set alarm level and hysteresis menu
Hint:
Hint:
07931001B revision 2
If you configure one measurement alarm as low and the other as high,
make sure that the high alarm and hysteresis levels are higher than
the low alarm and hysteresis levels. If you do not, the analyser can be
permanently in an alarm condition until you correct the levels.
Make sure that the measurement alarm and hysteresis levels are not
too close to the expected sample measurements. If your sample gas
concentrations contain minor variations that are acceptable, spurious
alarms will be reduced.

Note: You can specify the relay coil state (energised or de-energised) to meet any particular
application requirement. For example, Relay 1 coil is de-energised during an active status
when a measurement or analyser fault is detected. Therefore if the power to the analyser
fails, or the relay cable is disconnected, a fault is raised because this is electrically the
same as if Relay 1 is de-energised. This is a ‘fail-safe’ situation. In some applications it is
preferable that the relay is energised in an active status.

DC Gain 1 and DC Gain 2 are typically set for each application and may need to be
changed during comissioning to obtain optimum performance.
Note:
If the photodiode DC level is too high an error status will be raised and
the analyser will report incorrect readings
For example in dusty processes where the dust loads vary significantly,
if the gain levels are set when dust loads are high, saturation of the
photodiode may occur when dust loads drop to a minimum.
Note:

The analyser must be correctly aligned before adjusting the gain. For
guidance on this see section 7.3.1, 7.3.2 and 0 .

5.3.9 SD card
Only remove the transmitter enclosure cover to access the SD card if
there is a negligible risk of pollution of the electronic circuits due to
moisture, liquids, dirt, dust or other contamination.
Before you refit the covers, make sure that the sealing gaskets are clean,
dry and undamaged. Replace and secure all covers as soon as possible
after you complete your task within the enclosure.
When you use an SD card to transfer data logs from the analyser, make
sure that the transmitter enclosure cover is closed and secured,
otherwise the EMC protection measures will be invalidated and the
results recorded may not be valid.
When inserting or removing the SD card take care not to accidentally
remove the metal card holder as, when open, the holder can slide
backwards / out and be disconnected from the PCB. Before closing the
enclosure ensure the holder is secure.
Figure 5-5: Micro SD connector
The Laser 3 Pluswill support memory cards with capacity between 128Mb to
32Gb.
Note: The Analyser software will use up to a maximum of 2Gb of storage
memory for a single file.
07931001B revision 2
© Servomex Group Limited. 2017
92
Large datalogs (> 200000 records) can take extended periods of time (> 10
minutes) to export to the micro SD Card
The largest number of log records that can be stored on 2Gb SD Card is
775507 records taking approximately 30 minutes to export.
Note:
MicroSD Card speeds do vary and can have a significant effect on export
timings.
Note:
Unformatted Micro SD cards are not supported by the analyser. MicroSD
cards should be formatted as FAT32 format prior to insertion. If an
unformatted card is inserted an error would be given only when a user attempt
to use the card by turning logging on or saving settings.
Note:
When inserting or removing the SD card take care not to remove the metal
card holder as, when open, the holder can slide backwards and out. And be
disconnected from the PCB.
To open the cover, slide the latch to the left.
Insert the micro SD card into the slots in the cover.
Close the cover and push the latch to the right to secure it.
The SD card connector is used for:
• Data logging
• Software updates
• Settings (save / restore)

6.2 Removing the transmitter and receiver units from the process
Note:
Hint:
The calibration cell is supplied with a TU / RU connection cable
fitted with terminal connectors. Therefore, when the TU / RU units are
unplugged and un-coupled from the process, the connectors, cables
and gland plates can remain with the process while the analyser is
being calibrated. Cover / protect, gland plate, connectors and cables during
this time.
When physically un-coupling and removing the transmitter and receiver
units care should be taken to avoid disturbing, and potentially misaligning,
the balljoint flange.
Before disconnecting the TU and RU from the process ensure there is no
risk from exposure to potentially harmful gases.
Before disconnecting the TU and RU from the process ensure there is no
risk from exposure to potentially harmful gases.
Before disconnecting the TU and RU from the process ensure there is no

Before fitting the analyser to the calibration cell check the windows are clear of process
residuals. If required clean the windows.
Only use a soft, clean cloth moistened with water to wipe clean the
outside of the enclosure.
Optical glass window must be cleaned with isopropanol only.
Ensure the cables and pipes connected to the analyser and calibration
cell are routed so that they do not present a trip hazard.
The pressure in the calibration cell shall not exceed 1.5 bar absolute.
Before using the calibration cell, ensure all connections are leak free at
operating pressure.
Calibration gases are potentially harmful ensure adequate ventilation is
provided.

Purging gases are potentially harmful ensure adequate ventilation is
provided.
Before disconnecting the TU and RU from the calibration cell ensure
there is no risk from exposure to potentially harmful gases.
Ensure the laser beam is switched off before disconnecting the TU and
RU from the calibration cell.
Note:
We recommend that you use an absolute pressure sensor to measure the
gas pressure in the cell to provide the instrument with correct gas pressure
during the verification and calibration procedure. If a pressure sensor is not
fitted to the calibration cell then a suitable blanking plug should be used.
Note:
If only the ambient pressure is known or the pressure sensor is
located far away from the cell, switch off the gas flow before
calibration, wait for 1 minute for the readings to stabilise and then
perform calibration. In this case the gas pressure is equal to the
ambient pressure.
The transmitter and receiver should be connected to the calibration cell and be purged
with a none absorbing gas, usually nitrogen, via Purge Port 1, Measurement In, ref
Sections 2.2‘and 2.3.
Ensure that Purge Port 3, ‘Enclosure Out’, is free to vent to
atmosphere.
The Purge Compensation function, ref. Section 4.3.1
Purge compensation must be Disabled during calibration on a calibration cell, ensure
this is the case. Calibration can then be performed as described in Section 6.7.
After calibration is completed, the instrument must be returned to the
correct process settings, including Purge Compensation being
‘Enable’ if applicable. Other settings include path length, pressure and
temperature.
Transmitter and Reciever purge ports should also be checked, so that
they are returned to the correct process and purge requirements at
installation.

Adjust the ‘physical set up’ to suit the calibration cell environment. Path length,
pressure source, temp source, analogue I/P.
Note:
If the analyser has been set with a long measurement filter the filter should
be reset the an appropriate time for example, 10 seconds.to avoid a poor
calibration result.

Note:
Before you attempt to calibrate the system, let the instrument operate until
stable.
Note:
Before calibration proceeds clipping function should be disabled if active.
6.7.1 Calibration general sequence
If required, connect and start purging of dead volumes in TU and RU Purge 1 –
Measurement or Environmental IN e.g. for an O2 measurement.
Connect calibration gas and flush system for a minimum of 15 minutes, (30
minutes recommended). Typical flows between 500 to 1000 ml/min
Note: Measurement purge requires ventilation
Note: Ensure zero readings for zero gas concentration
Wait for the system to reach a stable reading, measurement stability must be
assured before requesting calibration
Check that the reading agrees with the concentration of certified gas within
specified tolerance, then press calibrate

to avoid disturbing, and potentially misaligning, the mounting assembly.
Note: For the following gases O2, CO2, and H2O present in the atmosphere, all the
dead volumes inside and outside the instrument enclosure must be purged with
N2 during a calibration.
101
© Servomex Group Limited. 2017
07931001B revision 2
There are two distinct calibrations for the instrument to be performed in correct
sequence:
6.7.2 LO or zero calibration
During this process, you must flush the cal cell and all the dead volumes inside the
analyser with nitrogen for a duration of at least 15 minutes at flows between 500 ml
to1000 ml/min. The customer must enter 0 in the box called CAL1C and enter all the
parameters such as Pressure, temperature and pathlength before performing a LOW
CAL.
Hint:
The graph page should show a flat line in the gas line location.
6.7.3 HI calibration
During this process, you must flush the cal cell with the gas from the calibration bottle
for a duration of at least 15 minutes to 30 minutes (longer for adsorbing gases such as
NH3) at flows between 500 ml/min to 1000 ml/min.
The customer needs to enter their precise cal bottle concentration in pp,% or other
units they have previously selected in the box called CAL2C in addition to ensure all
the parameters such as Pressure, temperature and pathlength are set correctly before
performing a HIGH CAL.
Note:
Ensure that measured gas concentrations reach maximum and stabilized with
no oscillations, and that 2f harmonic graph are correct and as expected, only
calibrate if 2f graph and line positions are in correct locations, the 2f burst has
correct amplitude and the 2f signals are correct and of sufficient amplitude.
Note:
Calibration in the absence of a surrogate gas line lock must not be attempted.
Note:
When restoring a previous calibration, the time since last calibration will not be
updated.

6.11 Dependant measurement calibration
In products which have multiple measurements available one or more measurement
will be dependant on the primary measurement. These measurements cannot be
seleted for calibration, these measurements are proportionatly calibrated when the
primary measurement calibration is completed.
6.12 In situ validation (in-line span or zero check)
6.12.1 Overview
To allow validation checks of the Laser 3 Plus analyser when attached to the process,
the optional validation cell (100 mm) must be fitted between the TU mounting and TU.
Suitable O-ring and sealing materials must be specified for the specific application
gasses.
The Analyser may fail if you use materials to connect the Laser 3 Plus to
the process that are not compatible with the application gasses.
Note:
As the test is performed swiftly, it is assumed that the process conditions will
be reasonably stable during this procedure.
Note:
Filters must be turned off before validation.
Note:
Check the validation gas type and concentration.
6.12.2 Validation process
1. Switch on zero gas (a gas which does not contain or has negligible concentration of the
target gas) to purge in-line span cell for a minimum of 5 minutes
2. Monitor concentration and verify that 2f signal reduces.
Note:
Typical flows between 500 to 1000 ml/min
3. The baseline subtraction function should now be used to zero out the analyser before
validation gas is introduced to the in-line validation cell.

7.1.1 Installation location
Make sure that you mount the Laser 3 Plus on a structure that is able to
support its mass (refer to 2.6.1 for the transmitter unit and for the
receiver unit).
The environmental operating conditions for the Laser 3 Plus are listed in
Section 2.6.5.
Make sure that all floors and platforms are clear and free from
obstructions, and that the engineer has sufficient space to move freely
and change posture.
The Analyser may fail if you use materials to connect the Laser 3 Plus to
the process that are not compatible with the process environment.
When you decide where to place the Laser 3 Plus in the process, we recommend a
minimum of 5 stack diameters of straight duct before and 2 stack diameters of straight
duct after the measurement point. Recommended distance from the process wall, duct
or pipe to the welded flange is a minimum of 100 mm. This will need to be increased,
or thermal break added, for process temperatures above 135 oC.
7.1.2 Analyser placement
You should place the transmitter and receiver units so they are easily accessible. A
person should be able to stand in front of the transmitter to view the display and access
the alignment mounting to make adjustments. Cabling exiting the Analyser should also
be considered.
Each unit requires at least 500 mm (19.7 ") of free space (measured from flange to the
stack and outwards).

7.1.3 Process flanges
The Laser 3 Plus attaches to process flanges that you must weld either to the relevant
process pipework, duct or furnace wall or, for pipework up to 150 mm (6 ") in diameter,
to a spool piece supplied by Servomex.
You can attach the laser analyser mounting assemblies (fixed or adjustable) to the
process flange either directly with appropriate gaskets, or via an isolation valve or an
isolation window, depending on your application. If your process is corrosive, toxic or
flammable, you must use isolation valves that are mechanically and chemically
compatible with the process. When these valves are closed, you can easily remove the
analyser from the installation for maintenance procedures without stopping the
process.
Always wear the appropriate PPE to minimize the risk of burns.
The maximum process pressures for the Laser 3 Plus are listed in
Section 2.6.6. For installations based in the European Union, in all
applications operating above the maximum process pressures, the
Pressure Equipment Directive (PED) applies and an appropriate isolation
flange must be fitted.
Install and use the isolation flanges in accordance with their
manufacturer’s instructions.
If the process gas temperature is greater than 135 °C (275 °F), make sure
that you provide adequate thermal isolation to ensure that the maximum
temperature reached by the process flange to which the Laser 3 Plus is
fixed does not exceed 135 °C (275 °F).
Hint:
Servomex can provide thermal spacers for a range of flange sizes.
It is important that the process flanges are aligned correctly as they are
critical to ensuring the successful alignment and maximum
transmission of the Laser 3 Plus.
The Laser 3 Plus requires 2 holes of at least 25 mm (1”) in diameter to be cut
diametrically opposite to each other in order to enable the laser beam to pass through
the process gas.
Note:
The size of the hole depends on the process flange that you are using,
application and path length.
The flange dimensions are listed in and the following tables.

Process flange alignment tolerances
The transmitter and / or receiver instrument flanges are provided with an alignment
mechanism that allows limited manual adjustment of the laser beam direction in 2
planes.
So that this operates correctly after the instrument is installed, use the following
tolerances for positioning and attaching the process flanges.
Figure 7-3: Process flange bolt arrangement (4 bolt pattern)
111
© Servomex Group Limited. 2017
07931001B revision 2
The flange bolt pattern must be:
4 bolt pattern
45 °
8 bolt pattern
22.5 ° (not shown)
Acceptable
Not acceptable
Figure 7-4: Process flange positioning tolerance
Note:
7.1.4
Failure to align the transmitter and receiver flanges may adversely affect the
performance. Tolerance to misalignment is dependent on divergence, path
length and measurement. For further advice contact Servomex or local
representative.
Mounting rigidity
Make sure that the flue wall is strong enough to support the weight of the
Laser 3 Plus transmitter and receiver units, including the mounting
flanges and unsupported cables.
Install the Laser 3 Plus on a structure that is capable of supporting the weight of the
transmitter unit (TU) and receiver unit (RU). If the structure is not strong enough, you
will experience alignment problems during commissioning and operation.

The following illustrations of a high temperature mounting arrangement for the TU and
RU, where the units have been mounted 200 mm (7.87 ”) from the process wall.
Particular attention is required on the TU as the extra weight may require reinforcement
of the process wall to counter the moment produced by the distance from the process
wall.
Always allow for the weight of the cable in addition to the weight of the TU and RU.
The 'free-hanging' un-supported weight of cables should not exceed the
weight of the unit.

If the process wall is not strong enough to support the TU or RU, Servomex
recommend that you use a reinforcement plate.
Note:
It is your responsibility to assess and design the reinforcement plate that you
will use in your installation, subject to local conditions.
This reinforcement plate could be part of the process flange (as shown in diagrams) or
a separate reinforced section of the process wall.

As the TU weighs considerably more than the RU, support for the RU is less of an
issue. However, you should use a similar mounting arrangement for consistency.

An alternative to the reinforcement plate is to provide ceiling or floor supports
to hold the weight of the TU or RU, although these may impact on the ease
of alignment and adjustments.

7.2.1 Safety
Do not install the Laser 3 Plus in a high velocity dust-laden atmosphere.
You are responsible for ensuring that:
•
•
•
•
•
•
The instrument is installed correctly and safely
The laser beam is enclosed during operation
The sampling system is leak free (if being used in bypass
extractive configuration)
The venting system is appropriate for the gases you are sampling
The installation does not introduce trip hazards
Appropriate PPE is used for installation, servicing and
decommissioning
Lubricate flange mounting threads with supplied anti-seize paste before
you install the Laser 3 Plus.
The optical windows in the receiver and transmitter units are installed in
the factory. Do not touch the optical windows as any contamination will
adversely affect the performance of the Laser 3 Plus. For cleaning
guidance see section 8.3.
Regularly inspect, test and replace seals to ensure that all external
connections are always leak-free at full operating pressure.
The equipment is incapable of passing the dielectric strength test
prescribed by the standards, and so this must be taken into account
during installation by using an SELV power source with a prospective
short circuit current not exceeding 40A.

7.3 Process connections
7.3.1 Fitting the transmitter and receiver alignment assemblies
Before you fit the transmitter and receiver alignment assembly to the process:
Make sure that there are no dangers from the release of potentially
hazardous gases, for example, toxic, flammable, asphyxiant or hot
gases.
Never look into a live process through the eye piece as this may result in
hazardous radiation exposure and permanent eye damage.
Always use adequate eye protection to prevent injury from ejected dust
or dirt and high levels of IR radiation that may be present.
Make sure that the exposed metal parts of the process are at the same
potential as that of its surroundings. If not, use suitable protective
equipment to provide protection against the risk of electric shock.
Make sure that the Laser 3 Plus is switched off.
Note:
The mounting / alignment assemblies are adjustable; the receiver alignment /
purging flange may be fixed for shorter path lengths.
Bolt the transmitter and receiver instrument flanges to the process flanges using the
standard bolts, nuts and washers provided.
Note:
Use an anti-seize paste on these threads only. Anti-seize paste must not be
used on any other fasteners, nor be allowed to contaminate the optics.
The tolerances of the standard flanges, bolts and holes allow them to be misaligned
from concentric. Therefore when you fasten the flanges, make sure that the two flanges
are concentric to aid laser beam alignment.
Note:
If the process flange temperature is in excess of 135 °C, use a thermal spacer
insulating flange gasket to minimise heat transfer to the instrument flanges.
Ensure flange o-rings are fitted to the analyser mounting flanges.
Note:
119
Orientate the mounting assembly so that the purge connections are pointing to
the left (as viewed looking at the process wall) to ensure the TU and RU
mount vertically.

Do not use the alignment tool if the process flange is hot (> 60 °C), or if
the process contains potentially hazardous gases.
Only use the light source supplied by Servomex with the alignment tool.
Make sure that there are no dangers from the release of potentially
hazardous gases, for example, toxic, flammable, asphyxiant or hot
gases.
Always use adequate eye protection to prevent injury from ejected dust
or dirt and high levels of IR radiation that may be present.
Never look into a live process through the eye piece as this may result in
hazardous radiation exposure and permanent eye damage.

Refer to
Step 1
Switch on to light source in order to check operation before fitting
then fit the alignment tool light source assembly to the Analyser
flange (fixed or adjustable) on the RU side of the process using 3
off M6 x 16 screws. Switch the light source on
Step 2
Fit the alignment tool eye piece assembly to the Analyser flange
(adjustable) on the TU side of the process using 3 off M6x16
screws. Peel back the protective boot on the ball joint assembly to
reveal the adjusting screws (Figure 7-10)
Note:
Step 3
Loosen the adjustment nuts and screws by turning anti-clockwise.
Ref (Figure 7-25)
Step 4
For correct alignment the light source must be in the centre of the
eye piece. If the eye piece is off target adjust the TU/RU alignment
assembly tighten the adjustment screws to lock the assembly in
position. This is easiest to do with two hex keys, one to loosen and
the other to tighten.
Note:
All adjusting screws have a right hand M6 thread, and give an
angular resolution of 1.8º per screw turn. The ball joint may be
adjusted by ±4º in each direction
Step 5
When all adjustments are complete, ensure all screws are locked in
place
Hint:
121
Ensure all the M6 x 16 screws are tight before beginning the
alignment process.
Taking care not to change the position of the assembly during step 5 and 6.
Step 6
Remove the alignment tool scope assembly and replace the boot
immediately
Step 7
Switch off the alignment tool light source assembly and remove it
from the RU
Step 8
If the analyser has been supplied with an adjustable, rather than
fixed mounting assembly at the receiver end, fit the alignment tool
light source assembly to the analyser flange on the TU side of the
process as described in step 1. Fit the alignment tool scope
assembly to the RU side of the process as described in step 2 and
repeat steps 4 to 7, to align and secure the second analyser
mounting assembly.
Note:
The adjustable receiver mount is adjusted by a combination of set
screws and mounting screws, see Figure 7-26.

Figure 7-10 Alignment tool
The alignment tool comprises a LED light source and eye pieces which are fitted to an
adaptor on each opposing flange. Align in accordance with tolerances in section 7.1.3
by lining up the eye piece with the light source until the LED source is concentric to the
relative bores and eye piece.
For extended path lengths (over 5 meters) an eye piece with integrated scope is
available with an optical magnification factor of 4X and crosshair target.
The alignment tool is NOT Ex certified.
It CANNOT be used where a FLAMMABLE atmosphere is present in the
‘Outside atmosphere’ or the ‘process atmosphere’.
It MUST NOT be used where an EXPLOSIVE atmosphere is present in the
‘outside atmosphere’ or the ‘Process atmosphere’.
The alignment tool shall not be used where there is a risk of exposure to
hazardous gases contained in the process.
7.3.3 Fitting the transmitter and receiver on the flange
Inspect all joints when you have connected the Laser 3 Plus to the
process.

122
Do not apply power to the transmitter unit before both the transmitter
and receiver units are fitted to the Analyser flanges and front panels
have been closed. This ensures that there is no risk of exposure to laser
light.
Make sure that there is enough space at the base and sides of the
enclosure to open the covers and to route cables and pipework without
tight bends.
Note:
Although the following diagrams show the TU, use the same technique for the
RU.
Check the o-ring is in place on the transmitter / receiver flange before
installation.
Loosen the 3 x M6 screws and align them with the corresponding keyhole slots on the
flange joint (Figure 7-11).

7.6 Purge connections
Note:
Purge connections are listed in section 2.6.3.
7.6.1 Alignment / purging assemblies
Make sure the purge gas pressure is above that of the process being
monitored to avoid exposure to hazardous gases leaking from the
process.
Make sure that the flange purges are connected and operational before
you connect the transmitter and receiver units to the process. If you do
not do this, the Laser 3 Plus optics could be damaged by the hot
process.
Hint:
Servomex recommend that the purge gas is supplied using flexible piping to
minimise strain on the alignment assembly.
The instrument windows are kept clean by setting up a positive flow of air through the
alignment / purging flanges and into the stack. This purging prevents particles settling
on the optical windows and contaminating them.
Use non-hazardous gas for purging. The purge gas must be dry and clean. Specific
gas selected is application dependent.
Hint: For Fixed pipe installations a typical flow rate is between 20 and 30l min-1. For all
other configurations, set an initial purge flow in the flange to approximately 1/10 of the
gas velocity in the duct.
After you have completed the installation, optimise the purge flow for your specific
application.
Note:
Purge flows that are too low may cause blockage or contamination of the
07931 series Laser.
Note:
Purge flows that are too high may cause dilution of the measurement gas.
If in doubt, please contact Servomex or local representative for further advice
Note:
The air quality should conform to the standard set by ISO 8573.1, Class 2-3:
particles down to 1 micron should be removed, including coalesced liquid
water and oil, and a maximum allowed remaining oil aerosol content of
0.5 mg/m3 (4.99423685 × 10-4 oz/cubic foot) at 21 °C (70 °F) (instrument air).
Note:
Some instruments require nitrogen purging grade 3.0 or higher, for example,
O2 instruments for temperatures below 500 °C (932 °F).
If in doubt, please contact Servomex or local representative for further advice

7.6.2 Enclosure environmental / measurement (instrument) purge
Make sure that you vent purge gases carefully to avoid creating a hazard.
If using toxic, asphyxiant or flammable sample or calibration gases,
always purge the enclosures with non-hazardous gas during operation to
reduce the risk of hazardous concentrations accumulating within the
analyser. Purge the enclosures for a suitable time before opening to
ensure any concentrations are reduced to safe levels. Open transmitter
or receiver enclosures in a force ventilated open area, or in another
appropriate environment in which any hazardous gases are directed
away from the user.
Make sure that the vent for environmental / measurement (Instrument)
purge gas is clear and unobstructed so that the Laser 3 Plus enclosure
does not become pressurized or its IP rating compromised.
Ensure the pressure of the measurement purge exceeds the pressure of
the environmental purge gas to avoid backflow.
If the purge delivery system cannot be flow limited, the performance of
the analyser may be degraded and the equipment may be physically
damaged.
For applications where purging of the transmitter and receiver units is required for
measurement or cooling, you must make sure that the direction of flow is as shown in
Figure 7-22: Transmitter purge and Figure 7-23: Receiver purge.
The transmitter and receiver units have internal optical surfaces. The purge gas must
be clean and you may need to add additional filtering. Use Nitrogen or other nonhazardous gas as a purge gas. Make sure that the purge flow is less than
0.1 litres/minute (0.004 cubic ft/min) to avoid pressure build up inside the units.
139
Note:
In ambient environments where dew points may exceed 15°C, Servomex
recommends the use of measurement and environmental purge with dp <15°C
for the Transmitter unit (Ident 6 in Figure 7-22) in order to prevent
condensation.
Note:
Some instrument air may contain small amounts of oil and water which will
quickly damage the optical windows, mirrors and lens in the receiver and
transmitter units. Ensure proper precautions are taken to avoid this.

7.7.2.2 Alignment of the TU (Laser gain adjustment process)
Before the Analyser can be used it must be set up and the laser adjusted and aligned
correctly so that the receiver diode is receiving the optimum laser intensity
The following steps describe the process.
Note:
Servomex recommend saving current settings before starting the gain
adjustment.
The physical alignment of the ‘ball joint’ flange will need to be adjusted to ensure the
output is within this range.
141
Step 1
Peel back the boot on the transmitter mounting assembly to show the
ball-joint alignment screws Figure 7-24
Step 2
Adjust the 4x screws to change alignment until maximum Photodiode
DC voltage achieved.
Note:
Only small adjustments should be made (half turn maximum per
iteration).
Step 3
If signal greater than 1.5 V, Lower Gain 1 or Gain 2 and note new
level of signal.
© Servomex Group Limited. 2017
07931001B revision 2
Step 4
Repeat Steps 2 -3 until the maximium Photodiode DC voltage
achieved is between 1.2V and 1.5V
Step 5
When all adjustments are complete, gradually tighten all adjusting M6
screws A, B, C and D and nuts, then replace covers (Figure 7-25),
taking care not to change the position of the assembly.
Step 6

7.7.2.3 Receiver unit alignment
Step 1
Step 2
Unscrew 4 Set Screws on the RU adjustable flange until they do not
protrude the RU adjustable flange
Using the Gap Gauge 07931503, tighten the 4 x M16 nuts / bolts on
the receiver flange to leave an equal gap of 6.0 mm around perimeter
of the RU adjustable flange – see Figure 7-27
Step 3
To align using the LEDs, watch the receiver alignment LEDs on the
receiver unit as you tighten in turn each of the 4 M16 adjusting
screws.
Note:
The LEDs flash according to the direction of the adjustment.
The first and fifth LEDs will illuminate when a large change in
alignment has occurred, whereas, the second and fourth LEDs will
illuminate when a small change in alignment has occurred (either
positive or negative – see Figure 7-29).
The first and fifth LEDs will remain illuminated when the photodiode
DC level has exceeded a pre-set voltage threshold and adequate
alignment is achieved.

Step 4
When all adjustments are complete, tighten the 4 M10 set screws in
order to lock the position
Note:
Depending on application details it may be required to readjust the
photodiode DC level several times to ensure the target DC voltage
level does not exceed 2.7 volts. To check the DC voltage level refer to
4.11.1.
Note:
The receiver alignment LEDs can only be used when the receiver is fitted with
an adjustable mount (not a fixed mount), and you are adjusting the mount at
the receiver end.

8.2 Routine maintenance
Make sure that all gas connections to the process are regularly tested for
leaks. If you find any, do not use the equipment until you have corrected
the faults.
Do not attempt to maintain or service the Laser 3 Plus unless you are
trained and competent.
Service personnel must verify the safe state of the equipment after all
repairs. If you do not:
•
•
•
•
people may be injured
the protective facilities incorporated into the design of the
instrument may not operate as intended
sample gas measurements may not be accurate, or
the instrument may be damaged
The Laser 3 Plus may be attached to equipment that is hot. Always wear
the appropriate PPE to minimize the risk of burns.
Turn off the power to the Laser 3 Plus before you attempt to remove the
transmitter and receiver units from the process, remove the receiver unit
enclosure cover for any other maintenance work. This ensures that the
laser beam is switched off and there is no risk of exposure to hazardous
laser radiation.
Sample gases may be toxic, asphyxiant or flammable.
Before you remove the Laser 3 Plus from the process, make sure that it
does not contain any potentially hazardous or heated gases, or is at a
pressure below atmospheric pressure.

8.3 Cleaning
Only use a soft, clean cloth moistened with water to wipe clean the
outside of the enclosure.
Optical glass window must be cleaned with lint free cloth, isopropanol
can be used if required.
Figure 8-6: Optical windows
8.4 Routine checks
The Laser 3 Plus contains no moving parts and does not need to be fitted with any
consumables. You only need to carry out simple maintenance procedures every 3 to 4
months. Carry out the following regular checks to ensure continuous and safe
operation of the analyser.
8.4.1 Daily
Check optical transmission
The frequency of checking depends on the level of
process condensates, particulates and vibration.
You can do this automatically if you use instrument output
(option), or via a warning relay.
8.4.2 Weekly
Check purge flow rates
Use a flow meter on the purge panel to check the purge
flow rates are the same as at the time of commissioning.
.
153

07931001B revision 2
8.4.3 Monthly
Check LEDs and display
Check the LEDs and displays are legible on the receiver
and transmitter units. Clean them if necessary.
8.4.4 Three-monthly
Check purge flow rates
Use the flow meters on the purge panel to check the
purge flow rates are the same as at the time of
commissioning.
Leak check the purge fittings.
8.5 Alignment / purging flanges
Do not disconnect the pipes from the alignment / purging flanges if there
is a risk to personnel or the environment from exposure to the potentially
hazardous gases contained in the process being monitored.
Failure of the purge will severely damage the optical surfaces of the
Laser 3 Plus.
Test the alignment / purging flanges for leaks at regular intervals as required for the
specific process and installation conditions.
Inspect the pressure of the flange and window purge at regular intervals to ensure it is
higher than that of the process as required for the specific process and installation
conditions.
8.6 Enclosure purge and breather (if fitted)
Check the flow rates of the purge panel at regular intervals to ensure it is operating
correctly.
Inspect the breather (if fitted) at regular intervals to ensure it has not become blocked
or otherwise damaged.
8.7 User replaceable spare parts
There are no user replaceable spare parts.
All Laser 3 Plus returned to Servomex or one of its appointed agents for servicing,
disposal, or any other purpose must be accompanied by a completed decontamination

12 Appendix Modbus setup
12.1 Implementation guide for Modbus communications
12.1.1 Introduction
This appendix details the implementation and use of the Modbus protocol in the analyser.
12.1.2 Supported function codes
For simplicity, only the following function codes will be supported.
Function
Description
Usage
01
Read coils
Read calibration status, pump state, etc.
02
Read discrete inputs
Read faults and alarm states.
03
Read holding registers
Read settings.
04
Read input registers
Read measurements, units, etc.
05
Write single coil
Change modes, perform calibration etc.
06
Write single register
Change single setting.
08
Sub Function
Diagnostic to test communications.
00 = Return
query data
16
Write multiple registers
Change multiple settings.
12.1.3 Exception codes
If an error should occur while processing a message one of the following exception codes will
be returned by the instrument.
163
Code
Condition
Meaning
01
Illegal function
Requested function code is not supported.
© Servomex Group Limited. 2017
07931001B revision 2
02
Illegal data address
The combination of data address and transfer
length is invalid for this function.
03
Illegal data value
A value contained in the query data field is not an
allowable value. This indicates a fault in the
structure of the remainder of a complex request.
This does NOT mean that a value to be stored in a
register is incorrect as Modbus has no means of
determining what is legal for any particular
register.
04
Slave device failure
An unrecoverable error occurred while the unit
was attempting to perform the requested action.
12.1.4 Addressing
Addresses in Modbus ADU (application data unit), run from 1 – N, whereas addresses in the
Modbus PDU (protocol data unit) run from 0 – N. This appendix gives addresses in the ADU
model. Depending on the particular Modbus master, addresses may have to be entered as
they are given or have 1 subtracted from them. For example to read register 101 an address
of 100 may be needed.
Note:
Slave ID: 247
12.1.5 Floating point numbers
Floating point numbers (e.g. 12.34, –1012.32, etc.), are digitally represented using the IEEE–
754 format. Single precision floating point numbers are used throughout and they require
32 bits of data. Since a Modbus register holds 16 bits it takes 2 registers to represent a
floating point number. We default to having the most significant word of the float, bits 16 –
31, in the first register, and the least significant word, bits 0 – 15, in the next register. This
order can be reversed by setting a coil in the system control mapping.
