1.4 Introduction and Measurement principle
The GPro 500 TDL is a precision optical instrument designed for continuous in-situ or extractive gas
measurement, based on tunable diode laser absorption spectroscopy (TDLS). The GPro 500 TDL provides a high performance & flexible gas measurement solution. It is supplied with a process adaptor
specific optimized for the application. For in-situ applications these include standard purged probes and
wafer cells, non-purged probes (with or without integrated particulate filter) & filtered wafer (W) cells. For
extractive applications, a variety of extractive cells options are available..
For in-situ applications utilizing the standard purged probe or wafer cell; to ensure
reliable measurement performance, it is important that there is flowing process
gas at the measurement location. See chapter 2.2 (Flow conditions at measuring
point) on page 28 and chapter 3.1.2 (Process side purging) page 31 for further
details. (This does not apply to non-purged probes or extractive cells).
GPro 500 TDL is suitable for use in industrial environments or environments
where it may be connected to a mains electrical network supplying domestic
premises.
The measuring principle used is infrared single-line absorption spectroscopy, which is based on the fact
that each gas has distinct absorption lines at specific wavelengths. The absorption lines are carefully selected to avoid cross interference from other (background) gases. Using direct absorption spectroscopy,
a spectrum in a specific wavelength range is taken and compared with spectral reference data stored in
the on-board database for any given temperature and pressure. The concentration is then calculated. Any
inconsistency between reference data and measurement data will trigger an alarm. The detected light
intensity varies as a function of the laser wavelength due to absorption of the targeted gas molecules in
15
Laser Spectrometer GPro 500
the optical path between the laser and the detector. The laser line width is a small fraction of the absorption line width so the reproduced spectra is very accurate. The instrument stores the spectral data in its
memory and once a scan is obtained a curve fitting to this data is performed yielding a measurement
value. Account is also taken to the process gas temperature and pressure and these parameters are
measured separately or they can be manually fixed.
The GPro 500 TDL is a gas analyzer and as such measures the FREE molecules
of the specific gas of interest. It will not detect such molecules when they are
bound together into larger molecular structures or when attached to particles
or dissolved into droplets. This should be carefully considered when comparing
measurement results with other measurement techniques.
1.4.1 Dust load
As long as the laser beam is able to generate a signal for the detector, the dust load of the process gases
does not influence the analytical result. By amplifying the signal automatically, measurements can be
carried out without any negative impact. The influence from high dust load is complex and is dependent
on the optical path length (probe length), particle size and particle size distribution. At longer path lengths
the optical attenuation increases rapidly. Smaller particles also have a significant impact on the optical
attenuation: the smaller the particles are, the more difficult the measurement will be. The general impact
on the measurement result in high dust load is an increased noise level. For high dust load applications,
please consult your local METTLER TOLEDO representative, see "Sales and Service" on page no 130.
1.4.2 Temperature
The temperature influence on an absorption line must be compensated for. An external temperature
sensor can be connected to the GPro 500. The signal is then used to correct the measurement results. Without temperature compensation the measurement error caused by process gas temperature
changes affects the measurement substantially. Therefore, in most cases an external temperature signal
is recommended. The manual mode with fixed temperature and pressure values is only recommended
with processes where these values are constant and well known. Temperature sensor requirements:
4 – 20 mA output, either active or loop powered, with range suitable for process temperature range. The
sensor must also meet the local hazardous zone requirements.
Temperature sensor accuracy requirements are: Pt100 or equivalent, +/– 0.01 °C or better, with configurable 4 – 20 mA outputs.
Rule of Thumb:
For oxygen measurements, typically a delta of 1 degree C equals 500 ppm O2 change in reading in
normal air, without compensation.
1.4.3 Pressure
The process gas pressure affects the line shape of a molecular absorption line and influences the measurement results. An external pressure sensor can be connected to the GPro 500. When the correct
process gas pressure is supplied, the GPro 500 uses a special algorithm to adapt the line shape and
effectively compensate for the pressure influence as well as the density effect. Without compensation the
measurement error caused by process gas pressure changes is substantial. Therefore, in most cases an
external pressure signal is recommended. The manual mode with fixed temperature and pressure values
is only recommended with processes where these values are constant and well known. Pressure sensor
requirements: 4 – 20 mA output, either active or loop powered, with range suitable for the process pressure range. The sensor must also meet the local hazardous zone requirements.
Pressure sensor accuracy requirements are: +/– 1 mbar or better, with configurable 4 – 20 mA outputs.
16
Rule of Thumb:
For oxygen measurements, typically a delta of 50mbar equals 1% O2 change in reading in normal air,
without compensation.
Note: It is recommended that a pressure sensor referenced to absolute pressure is used to negate errors
caused by atmospheric pressure variation. The pressure sensor must always be mapped to the
TDL input as an absolute sensor, so if a gauge sensor is used, the nominal atmospheric pressure
value will need to be added to the values entered for pressure min (4 mA) and pressure max (20
mA).
WARNING
Ensure P & T sensors are connected before applying loop power.
1.4.4 Cross interference
Since the GPro 500 derives its signal from fully-resolved molecular absorption lines, cross interference
from other gases is minimized. The GPro 500 is therefore able to measure the desired gas component
very selectively.
CAUTION
Always take great care when choosing the measurement location.
Positions where there are fewer particles, the temperature is lower or there is a more
suitable process pressure, are recommended. The more optimized the measurement
location is, the better the overall performance of the system will be.
Please consult your Mettler Toledo representative ("Sales and Service" on page no 130).

1.5 Instrument description
18
The GPro 500 TDL normally consists of 4 separate units: the TDL head, process adaptor, junction box
and the M400 transmitter (user interface). Additionally purging gas, (suitable for the application) and
4–20mA pressure and temperature sensor inputs are required in most cases. The general installation
diagrams for purged and non-purged probes, wafer cells and extractive measurements are shown on
Page 18
1.5.1 System Overview
A connecting device is required between the TDL and the M400 transmitter. For ATEX applications, an
existing junction box can be used, or one can be ordered as an accessory (see Appendix chapter 2.3
(Accessories) on page no 126). The 4–20 mA signals for temperature and pressure compensation are
connected to the sensor’s head via this junction box. The junction box also provides the connection point
for the GPro 500 Ethernet interface connection.. For more information in installation in hazardous areas,
please refer to chapter 8 (Explosion Protection) on page no 102.
In standard configurations the GPro 500 is connected to the M400 transmitter. This offers a flexible user
interface that not only displays concentration and other measurement parameters in real-time, but can
be used to configure specific analyzer parameters during commissioning and subsequent verification
and calibration of the system. This avoids the requirement for using a PC at the measurement location
to configure the analyzer. In addition, the M400 offers additional I/O capabilities, i.e. 4x 4…20 mA active
analog outputs and 6 relays. Alternatively, if GPro 500 is supplied as an additional output version. This
version provides 2 x 4…20 mA passive analog outputs directly from the sensor head and offers a full
Ex-d solution. In this case a M400 transmitter is not supplied and a M400 should not be connected to
the sensor head. To configure the optional direct analog outputs, it is necessary to use the MT-TDL software Suite to configure the GPro 500 during commissioning (using the Ethernet connection to the
GPro 500, see item 6 on see Figure 1 (General schematic of standard purge probe (SP) shown.) on
page no 19). For more information on the MT-TDL Software, please refer to chapter see 6 (Service) on
page no 80.

Figure 2 GPro 500, shown with standard probe (SP)
The GPro 500 consists of the TDL head which contains the laser module with a temperature stabilized
diode laser, collimating optics, the main electronics and data storage. It is housed in a coated aluminium
box. The process adaptor attaches to the TDL head. Dependent on the application, this may be a purge,
purge free or filter probe, in-line wafer cell or extractive cell. The TDL head has environmental protection
to IP65, NEMA 4X. The GPro 500 is installed by assembling the supplied purging and then mounted onto
the process flange DN50 or ANSI 2" – see (Dimensions of the DN50/PN25 flange for standard purge
probe (SP) and non-purged probe (NP) on page no 19). The optical alignment is robust and reliable and
does not require manual alignment. For the standard purge probe (SP) and wafer cell, purging prevents
dust and other contamination from settling on the optical surfaces. For clean and static processes (for
example headspace monitoring), a non-purge probe (NP) may be supplied. In this case process side
purge is not required.

Laser Spectrometer GPro 500
Approval for the M400 is Class 1 Div 2/Zone 2 ATEX. For installation in Zone 1
areas, see "Accessories" on page no 126 – Purging box for M400.
1.5.2 Sensor head
The combined tunable diode laser and receiver assembly is known as the TDL head. This contains the
laser, optics and all the electronics for laser control, signal processing, line locking, detector electronics,
data storage/retrieval, current outputs (optional), etc. The sensor head has an Ethernet interface, accessible via the junction box, for high level maintenance by the use of METTLER TOLEDO Process Analytics
specific software (MT-TDL). All components of the sensor head are non-wetted and are therefore under
normal conditions are never in contact with the process stream. The power required for the sensor head
is 24 V, 5 W minimum. The connection between the sensor head and the process adaptor (probe, wafer
or extractive cell) is a precision machined interface. Care should be taken to ensure that the metal surfaces are carefully aligned when installing the sensor head to prevent damage.
ATEX Version:
In the ATEX Version, the sensor head is supplied with a pre-configured cable already installed. Do not
open the sensor head for removing, altering, or replacing the cable. The standard cable length is 5 m,
but optional lengths of 15 m, 25 m and 40 m are also available. For the ATEX version, note that this cable
must not be removed or changed by the user as opening the TDL blue cover will void the ATEX hazardous
area certification.
WARNING
Opening the sensor head voids warranty and
violates the ATEX hazardous area classifications.
US Version:
The US version must be installed using a suitable cabling conduit system in accordance with local codes
and regulations. To aid installation, the unit is supplied without an attached cable. METTLER TOLEDO
recommends the use of suitable cables listed as accessories in Appendix 2 (Spare Parts and Accessories) on page no 123
The terminals are suitable for single wires/flexible leads 0.2 mm2 to 1.5 mm2 (AWG 24–16).
WARNING
The electrical installation must be performed in accordance
with National Electrical Codes of practise and/or
any other applicable national or local codes.
WARNING
Wait 2 minutes before opening the enclosure after de-energizing the system.
22
WARNING
When fitting the enclosure cover onto the sensor head,
the 8 x M5 fixing screws must be tightened to 8 Nm torque.
WARNING
For gas group A, sealing of the conduit is required at the enclosure entry.
For gas groups B, C and D, no conduit sealing is required.
1.5.3 Insertion probes
Probes exists in several versions, including purged (SP), non-purged (NP) depending on the application.
Both material of construction (windows, metals, O-rings, etc.) and insertion length can be customized
to particular needs.
1.5.4 M400 type 3 transmitter
This is the GPro Series user interface. With the M400 the user can set the necessary parameters for
operation, and control the alarm and I/O setup. The M400 will of course also display the measured
gas concentration, the process temperature and pressure as well as the transmission (signal quality/
strength). It features class 1 Div 2 FM approval (ATEX zone 2) and four 4–20 mA active analog outputs.
M400 also features ISM – Intelligent Diagnostics – which provides the following features::
–– Time to Maintenance Indicator (TTM). Real time, dynamic prediction of when the next maintenance
cycle is required for best operation. Action: Clean the optics (window, corner cube)
–– Dynamic Lifetime Indicator (DLI). Based on the DLI information, the transmitter tells you when it’s
time to replace the TDL. Action: Replace TDL (Expected lifetime >10 years)
1.6 Software
Software for the GPro 500 TDL consists of 2 programs:
• A program not visible to the user and integrated in the CPU electronics, running the micro controller
on the CPU card. The program performs all necessary calculations and self-monitoring tasks.
• MT-TDL Suite: a Windows based program running on a standard PC connected through the Ethernet
connection. This program enables communication with the instrument during installation, service,
calibration and normal operation. See chapter 6 (Service) on page no 80 for more details.
It is only necessary to connect a PC for advanced maintenance, normal installation and service/calibration can be done via M400. Both communication ports
(Ethernet and RS 485) to the M400 can be used at the same time. However,
during access with a PC no changes are allowed on the M400.
1.7 Laser classification
The diode lasers used in the GPro 500 TDL operate in the near infrared (NIR). It has an output power
which, according to IEC 60825-1 latest edition, classifies the GPro 500 TDL as a Laser Class 1M product.

Preparations
2.1 Tools and other equipment
The following tools are necessary to install GPro 500:
• 2 pcs open-end spanners for M16 bolts
• 1 pcs Allen key 5 mm for the locking screws on flanges and Tx lid screws
• 1 pcs Allen key 3 mm for the RS 232 cover screws
• 1 pcs flat screwdriver 2.5 mm for electrical connections
• 1 pcs flat (6 mm) or cross head (No 2) screwdriver for Rx lid screws
• Adjustable wrench for purge connections
Other equipment necessary, not supplied my METTLER TOLEDO:
• Check valve
• Process side gasket (99 x 2.62 mm)
2.2 Flow conditions at measuring point
When deciding the placement of the GPro 500 TDL in the process, we recommend a minimum of 5 pipe
diameters of straight duct before and 3 pipe diameters of straight duct after the point of measurement.
This will lead to laminar flow conditions which is favorable for stable measurement conditions.
2.3 Measuring head placement (probe installations)
The TDL head should be easily accessible. A person should be able to stand in front of it and adjust the
M16 fixing bolts using two standard spanners. There should be at least 60 cm free space measured from
the flange fixed to the stack and outwards as shown below.
60 cm (23.6")
60 cm (23.6")
Figure 5 Minimum free space at the process flange.

Laser Spectrometer GPro 500
US Version:
Installation in a Division 1 area requires conduit as well as cable glands approved for the area. The
explosionproof probe head will need final adjustment which requires movement of the probe head. To
faciliate this, you will need to provide and install an explosionproof flexible coupling (for example: Killark
ECF/EKJ) in close proximity to the probe head. The coupling needs to be long enough and installed within
your conduit system to minimize vibration and to faciliate final adjustment of the probe head which may
include rotation by max. ± 90 degrees. Please be sure to provide a coupling which is suitably long.
2.4 Flanges and stack hole requirements (Probe installations)
The probe requires one hole, at least 54 mm in diameter. Standard flange used for connection is DN50/
PN25 or ANSI 2“/300 lb. The flange can either be welded directly to the process, or optionally be part of
a bypass system The two flanges are shown in Dimensions of the DN50/PN25 flange for standard purge
probe (SP) and non-purged probe (NP) on page no 30.
When the process flange is mounted it is important that the free space in front
of it is at least 60 cm to facilitate installation and maintenance. Se Minimum free
space at the process flange. on page no 31.
Gasket is not provided. See chapter Table 1 (Product data sensor head) on page
no 24 for information on suitable gaskets.
2.5 Cables and electrical connections
The TDL and M400 are connected with a RS 485 cable. The user should verify that the cable length
for the 4–20 mA analogue current output from the TDL does not influence the measurements (due to
inductance etc.). If electrical connections have to be made at installation, refer to chapter 5 (Electrical
Connections) on page no 67, 5M cable length statement.
ATEX Version:
WARNING
The GPro 500 comes with a pre-installed cable and cable gland.
Do not attempt to replace the cable as it will void the warranty
and violate the ATEX classification!
RS 485 cable specifications for the ATEX version: Lead area must be at least 0.5 mm2 and the maximum
length is 200 m. The specification for the Ethernet cable is CAT5.
32
US Version:
The FM version must be installed using a suitable cabling conduit system in accordance with local codes
and regulations. To aid installation, the unit is supplied without an attached cable.

Installation and Start-up
Laser Spectrometer GPro 500
This chapter describes the steps and measures needed to be taken during commissioning of the
GPro 500.
3.1 Installation and adjustments
3.1.1 Mechanical installation
The GPro 500 is designed to be very easy to install. The optical path is aligned in the factory so the installation procedure is simply to bolt it to the process flange, mount the purging tube (6 mm or optional
1/4" tube fitting) and mount the cables.
For efficient installation you must make sure that the pre-installation requirements
are met prior to the visit of the Mettler-Toledo technician.
For purged (SP) probes and purged wafer (W) cells, if the process is running or
if the optical surfaces will be exposed to contaminates or condensates following
initial installation, it is essential to connect and turn on the process purge. It is
recommended to initially run the purge gas at maximum flow (typically 10 l/min)
to protect the optics. This flow will be adjusted and optimized later during final

3.1.2 Process side purging
(not applicable to non-purged probe [NP] and extractive cell [E])
Depending on the type of process adaptor supplied, there may be requirement for either one or two
optical purges. These are called Instrument purge and Process purge.
Figure 7 on page 37 and Figure 9 on page 38 provides further details on the purge requirements for
the standard purge (SP) probe together with the typical configuration of the required external flowmeters
(rota meters) used to supply and control the purge gas flow.
Purge and non purge Probes without filter.
If installing an SP or NP probe without filter, ensure that the holes/slots are facing the process (verify that
the flat gasket between the probe and the sensor head is well installed) and ensure the flange gasket is
in place.
Non-purged with filter
Prior to inserting an NP probe with an installed filter, mark the position/angle of the DUST SHIELD on the
flange. When installing the probe, ensure that the DUST SHIELD is facing the process in coming flow and
ensure the flange gasket is in place.
Instrument Purge
The GPro 500 TDL head attaches to the process adaptor via a precision mechanical interface.
Between the optical window of the TDL head and the adaptor’s process window, there is a small cavity.
This cavity forms part of the optical path of the analyzer and therefore it is important that there are no
traces of the gas to be measured, i.e. O2 or H2O or other, in this space, otherwise this will add to the
measurement concentration. The instrument purge is therefore used to flush this space. In addition, in
the unlikely event of a breakage of the process window, the purge will flush process gas away from the
cavity.
Typical purge gas flow for instrument purge is < 1 l/min
Note: All current process adaptor types require instrument purge.
34
Process Purge
For standard purged (SP) probes and purged in-line wafer (W) cells, in addition to the instrument purge
described above, these also utilize a process purge to protect the optical windows from direct contact
with process gas. The process purge flow is adjusted during commissioning to provide sufficient flow to
provide this protection and to set the optical path length through the probe.
Note. Process purge is critical for the protection of the process wetted optical components and for correct
operation of the analyzer and therefore must be running at all times.
For oxygen applications nitrogen purge is required, or alternatively another clean, non-explosive, noncorrosive and dry O2 free gas. For other gas measurements, instrument grade air is normally recommended. The GPro 500 standard purged probes (SP) and purged wafer cells (W) are designed to
consume as little purge gas as possible while still keeping the process optical surfaces clean.
When bulk plant nitrogen (or instrument air for non O2 measurements) is not available gas cylinders can
alternatively be be used. The purge consumption during normal operation is less than 1 l/min. which
means that if you have ten bottles with 3300 Std Liters (Liters of gas when at “standard” room temperature and pressure) filled to 2500 psi (172 bar), which is typically large bottles, they will last at least
3 weeks. Process purge gas consumption rarely exceeds 5 l / min.
The purging of the probe optics is essential to avoid contamination of the probe optics during process
operation. After installation ensure that purging is operating before you start the process. The details are
described in chapter 3 of the operating instructions.
WARNING
Always start purging at maximum flow before starting the process.
WARNING
Purging must always be switched on in order
to avoid dust and / or condensate deposition onto the optical surfaces.
Another alternative is to use a nitrogen generator (for O2 applications) local compressed air supply (for
CO and H2O applications), as long as it is oil free and non condensing and meets the quality requirements laid out in ISO 8573.1, class 2–3, for instrument air.
The purging is attached to the 6 mm (optional 1/4") Tube Fitting. The purge gas then exits in front of the
first window and in front of the corner cube at the end of the probe see Figure 6 (Optimizing the purge
flow) on page no 36.
WARNING
The purge gas inlet for the process side must have a check valve to
avoid contamination of the purging system from process gas.
WARNING
Always start purging at maximum flow before starting the process.
WARNING
Purging must always be switched on in order
to avoid dust deposition onto the optical surfaces.
35
WARNING
Do not connect instrument and process side purging in series,
otherwise when disassembling the sensor heat the probe purging will stop.
3.1.3 Adjusting the purging flow (for standard purged [SP] and in-line wafer [W]
cells)
The flow rate of the purging will affect the effective path length and consequently the measurement value.
Therefore the following procedure should be used. Start with a very high flow rate and gradually decrease
it. The measurement value will then start at a low value and increase with decreasing purge flow. At some
point it will level out and stay constant for a while and then again start increasing. Choose a purge flow
in the middle of the constant region.
CAUTION
If the process flow rate remains constant this will be a good purge flow but the effective path
length will always be a function of the process flow rate so be observant on this.

3.1.4 Signal Optimization
When in installation mode, the current value of % transmission and the noise signal level (NSL) will be
displayed for 5 minutes on the M400 transmitter display, before automatically returning to measurement
mode. These two diagnostics values aid in optimizing the laser signal quality. This is accomplished by
loosening the securing clamp and slowing rotating the blue TDL head. Continue to rotate the head until
the NSL value is less than 40 and the transmission value is above 70%. Finally fully tighten the clamp
and confirm the values are still acceptable. (See "TDL Installation" on page no 41 for further details).
WARNING
The GPro 500, when fitted with the standard purged (SP) probe,
can not operate in process conditions where process gas stream velocity
is typically <1 m/s. This would make the effective path length
(see "Dimensions and Drawings" on page no 43) too variable.
For applications with sample flows <1 m/s, an in-line wafer cell option is
available. For static processes where the process gas is clean and dry
(non-condensing), for example; tank head space measurement,
a non-purge probe option is available.

The process side purge connection is fitted with a seal between the fitting and the purge h ousing to
conform to the pressurized equipment directive (PED). To ensure the integrity of this seal and to prevent damage when connecting the purge tube to the fitting, a back spanner (wrench) must be used
to securely hold the fitting body as the purge pipe nut is tightened, as illustrated in Figure 8 below.

WARNING
Instrument side purging must be sufficient in order
to maintain the temperature of the sensor head below the
maximum acceptable limit of < 55 °C (< 130 °F).
WARNING
When the process gas stream is on, the instrument side purging must always be on in order to avoid possibility of ingress of process gas stream into
the sensor head in the unlikely event of a TDL sensor head window failure.
3.1.5 Solar radiation and process radiated heat.
Exposure of the TDL head to very high temperatures, for example, solar radiation and/or excessive localised heat sources (such as radiated heat from process walls or adjacent equipment) can cause internal
overheating of the device. It is therefore important under these circumstances that adequate protection
is provided, either in the form of a solar shield/roof for solar protection, or a suitable heat shield in the
case of excessive radiated heat from nearby processes or equipment. If the TDL is exposed to excessive
heat for prolonged periods, under these extreme circumstances the measurement may be withdrawn and
the TDL will display a laser source error message. If this should occur, the device should be allowed to
cool to its normal operating temperature range and suitable remedial measures made to prevent further
overheating occurring. Should the sensor head be exposed to excessive high temperatures beyond the
specification, the laser may shutdown, and a laser source error message may be indicated. If this should
occur, power should be disconnected and the sensor head allowed to cool before restarting the device.
Note: The solar shield/roof should not enclose the TDL head, as a free flow of air should be allowed to
circulate at all times.

3.2 Alignment
The GPro 500 is carefully aligned when it leaves the factory and normally doesn’t require any alignment
during normal use. If misalignment is suspected you need to contact Mettler Toledo or you local supplier
(see Sales and Service on page no 130) and send the GPro 500 back to the factory for re-alignment.
When the GPro 500 sensor head is removed from the probe (or from the thermal barrier should this be
installed), for example for verification and/or inspection, it is not necessary to realign it when mounting
it back onto the probe (or heat barrier). However, we should recommend to turn the head until the maximum transmission is reached. Consult the M400 manual on how to see the live transmission value on
its display.
3.2.1 Signal Optimization
Note that when in installation mode, the current value of % transmission and the noise signal level
(NSL) will be displayed for 5 minutes on the M400 transmitter display, before automatically returning

tighten the clamp and confirm the values are still acceptable. (See "TDL Installation" on page no 41
for further details).
WARNING
The purge gas for the thermal barrier must always be
turned on when the process is running in order to protect the sensor head from permanent damage.
WARNING
The failure of the instrument side and thermal barrier purging system must
trigger an alarm. This alarm has to be implemented in th DCS ny the user.

If, however, small pressure variations around atmospheric pressure are to be expected, relative pressure sensors will produce better results; but the variations of the underlying barometric pressure will be ignored.
For relative pressure sensors, the minimum and maximum values must be mapped so that
the TDL can interpret the analog pressure signal as “absolute”, i.e. a fixed barometric pressure of 1013 mbar (for example) has to be added to the mapped values.

Electrical Connections
ATEX Version:
Most of the electrical connections are terminated at the junction box. All potentials are floating and none
of them should be grounded to the box. This applies to all connection tables.
WARNING
Ensure that the electrical installation of the TDL conforms to all
applicable local and national electrical safety requirements.
WARNING
Obey the safety instructions given below when you install the
TDL; if you do not, the TDL certification may be invalidated, the
TDL may not operate correctly, or it may be damaged.
WARNING
Isolate mains power before commencing installation.
WARNING
Make sure that power is disconnected or switched
off before connecting any cable.
US Version:
The US version must be installed using a suitable cabling conduit system in accordance with local codes
and regulations. To aid installation, the unit is supplied without an attached cable.
The terminals are suitable for single wires/flexible leads 0.2 mm2 to 1.5 mm2 (AWG 16–24).
WARNING
The electrical installation must be performed in accordance
with National Electrical Codes of practise and/or
any other applicable national or local codes.
WARNING
Wait 2 minutes before opening the enclosure after de-energizing the system.
67
Laser Spectrometer GPro 500
WARNING
When fitting the enclosure cover onto the sensor head,
the 8 x M5 fixing screws must be tightened to 8 Nm torque.
WARNING
For gas group A, sealing of the conduit is required at the enclosure entry.
For gas groups B, C and D, no conduit sealing is required.
Power supply ot the GPro 500 and M400
The GPro 500 and the M400 have to be powered separately:
–– GPro 500: 24 VDC, 5 W minimum
–– M400 transmitter: 20–30 V DC or 100–240 V AC
WARNING
Always check the complete wiring between the M400 transmitter, the
GPro 500 sensor head, junction box (if applicable) and external temperature and pressure sensors before switching on the sensor.
WARNING
Always check all the electrical and grounding connections before switching on the power.
5.1 Electrical Safety and Grounding
The GPro 500 does not incorporate an integral on/off switch. You must provide a means of externally
isolating the electrical supply from the GPro 500: use a suitable switch or circuit breaker located close
to the GPro 500, clearly marked as the disconnecting device for the GPro 500.
–– The electrical supply circuit must incorporate a suitable fuse or over-current protection device, set to
or rated at no more than 10 A.
–– The GPro 500 must be connected to an external protective earthing system via one of the screws for
the lid to the sensor head (see Figure 32 on page no 70).
–– Ensure that your electrical supply can provide the necessary maximum power consumption. Refer to
"Product data" on page no 24.
–– Equipment connected to the mA input, mA output, RS 485 and Ethernet must be separated from
mains voltages by at least reinforced insulation.
–– Ensure that the cables that you connect to the GPro 500 are routed so that they do not present a trip
hazard.
–– All signal and electrical supply cables must be rated for temperatures of 70 °C or higher. When you
carry out insulation testing, disconnect all cables from the GPro 500.
68
Power supply ot the GPro 500 and M400
The GPro 500 and the M400 have to be powered separately:
–– GPro 500: 24 VDC, 5 W minimum
–– M400 transmitter: 20–30 V DC or 100–240 V AC
WARNING
Always check all the electrical and grounding connections before switching on the power.
Instrument Protective Grounding
WARNING
It is important that the protective ground connection
provided at the analyzer enclosure is connected to a suitable
instrument grounding (earthing) point at the site of installation.
The GPro 500 is supplied with both internal and external protective grounding (earth) connections. The
external protective grounding connection is clearly labelled and consists of an M6 x12mm screw located
on the flange of the instrument cover. The internal protective grounding connections are located inside
the instrument enclosure and are used for connection of the cable outer screen. See drawing "Protective
Grounding." on page no 70 for location of protective ground connections.
ATEX Protective Grounding
Note: The European ATEX certified version is supplied pre-wired with the internal grounding connection
already terminated to the cable outer screen.
IMPORTANT: The instrument cover MUST NOT be opened under any circumstances, as this will invalidate the safety certification.
For the external protective grounding a suitable grounding cable should be appropriately terminated and
attached to the M6 x12mm protective ground connection. The other end of the cable should be terminated
at a suitable instrumentation grounding point at the installation site.
FM Protective Grounding
The FM certified version is supplied without an attached cable. When installing the multicore cable, the
cable screen should be appropriately terminated at one of the two internal protective grounding points,
using the supplied M4 x 6mm screw.
For the external protective grounding a suitable grounding cable should be appropriately terminated and
attached to the M6 x12mm protective ground connection. The other end of the cable should be terminated
at a suitable instrumentation grounding point at the installation site.
Grounding cable needs to be in accordance with the NEC regulations.

5.2 Sensor head connections
ATEX Version:
In the ATEX Version, the sensor head is supplied with a pre-configured cable already installed. Do not
open the sensor head for removing, altering, or replacing the cable.
The junction box is the interface between the GPro 500 and the M400 and also the Ethernet. Any suitable junction box approved for the hazardous area can be used. The GPro 500 can be supplied with the
optional accessory GHG 731.11 which is a suitable junction box supplied by Malux. The dimensions of
this is shown below:
WARNING
Opening the sensor head voids the warranty
and violates the ATEX certification.

Service
Laser Spectrometer GPro 500
6.1 Connecting a PC
The MT-TDL software is the GPro 500 service tool. With this software all parameters can be access and
all possible settings can be modified. To run it you need to connect a PC, with the software installed, to
the Ethernet port in the junction box as illustrated below.
P
T

When accessing the MT-TDL with a PC it is important to make sure that no work is performed at the same
time via the M400.
WARNING
When accessing the GPro 500 using the MT-TDL software,
work using the laptop or PC must comply with the restrictions in place for working in hazardous areas.

6.3 The MT-TDL software
The most important function of the MT-TDL software from a service standpoint is the log capabilities. When
connected to the GPro 500 with your PC it is possible to start a log of selected parameters for a defined
period of time. One can then disconnect the PC from GPro 500 and with the log data stored on the SD-card
it can easily be access at a later time. A log folder is created on the SD-card and the files within this folder
can either be sent to trained staff at Mettler Toledo for further investigation or it can be viewed locally on your
PC with the MT TDL log viewer. Files are stored in date stamped folders, one folder for each day.
The software has three access levels but the normal user will only use the first one (Normal). The remaining two access levels are restricted for use by METTLER TOLEDO personnel. You can perform the
following tasks under the Normal access level:

Analog output (Note: only available if connected to a TDL with this option)
Through different menus the necessary installation parameters may be set. After setting the necessary
parameters the PC is no longer needed. The GPro 500 has all the parameters stored in the internal
memory. The PC can therefore be disconnected and the GPro 500 can be turned off and on without
resetting the parameters.
Once the program starts the user is presented with a screen like the one in the illustration below. It consists of an upper part and a lower part. In the upper screen a plot of the signal processed absorption
lines and the model absorption lines are shown. The version of the service program is also shown to the
right (in the example here) as is also the IP number of the GPro 500.
The content in the lower part is specific to the function the user chooses – concentration trend, trans
mission trend, etc. The following paragraphs will discuss their content.

Figure 50 External sensors
6.3.5 Diagnostic
On this tab, several ISM related data is available. ISM (Intelligent Sensor Management) is
METTLER TOLEDO’s concept for proactive, real-time sensor health monitoring. The ISM relevant
data for the GPro 500 contain the following:
–– DLI (Dynamic Lifetime Indicator): The DLI indicates in days the expected laser diode remaining lifetime, based on current usage. This value is read-only and is a general indication of the
analyzer’s recommended duration until complete replacement. When the DLI reaches zero, the
analyzer will continue to measure but the alarm will appear in the M400 transmitter.
–– TTM (Time to Maintenance): The TTM is evaluating in real-time the remaining time until the
minimum recommended transmission value of 10% is reached. This evaluation is based on
the current rate of transmission loss under the present process conditions. When the TTM
reached zero, cleaning of the optics or even replacement of optics parts is recommended.
–– T-max extern: this is the maximum temperature at which the GPro 500 process adaption has
been exposed to from the process gas stream.
–– Operating hours: the service time of the GPro 500 in hours.
–– Create Diagnostic file: use this button for troubleshooting the unit. When the butten “Create
diagnostic file” is pressed, a ZIP compressed file is created after 15 seconds on the desktop.
The ZIP file contains:
–– the log file (equivalent to clicking on the “Get logfile” button).
–– 10 spc files containing the full spectral data of the last 10 seconds in service.
–– the ppm trend values
–– the % trend values
–– the calibration history file
The data ZIP file cannot be opened by the user. Please send the ZIP file to your METTLER TOLEDO

Calibration using a calibration cell (for O2 measurements only)
For a more accurate calibration the calibration cell can be used. Doing this the TDL
96
(the units head) needs to be removed from the probe. Then it has to be mounted on
the calibration cell according to the illustration below. Before calibration is started new
values for path length, temperature and pressure have to be entered on M400. Then
the calibration gas is flowed through the calibration cell and the calibration is done in
the calibration menu of M400.
During calibration with the calibration cell the process is still sealed and no extra
precautions need to be taken.

7.3 Maintenance
The GPro 500 TDL is designed to reduce maintenance to a minimum. Experience has shown that
maintenance interval of more than 3 months is acceptable for most applications. The maintenance
operations described in this section will secure a continuous and safe operation of the monitor.
7.3.1 Routine maintenance
GPro 500 has no moving parts and require no consumables. TTM and DLI in M400 can generate
maintenance requests - for instance if the transmission drops. For best performance, however, we
recommend to routinely carry out the following steps:
–– Check optical transmission regularly (daily). This can be done automatically by TTM and DLI
or WARNING relay or similar.
–– Clean windows when necessary (see below).
–– For applications where the concentration of the measured gas is normally zero (zero gas application): Check instrument response by applying some gas at least once every 12 months.
Apply sufficiently high gas concentrations to obtain a strong instrument response for at least
10 minutes (at least 70 minutes after power on). No warnings or errors should be displayed
during the test. Contact your supplier if you are in doubt about your instrument.
–– Check calibration every 12 months (depending on the required accuracy). Recalibrate if necessary, see "Calibration" on page no 100.
7.3.2 Remove the probe or wafer cell from the process
The GPro 500 is removed from the process by loosening the four bolts on the flange and carefully
extracting it. If necessary the purging connection may have to be removed as well. For wafer cell
removal, the process must first be stopped, or the pipe section isolated via closure of isolation
valves. The flange mounting bolts can then loosened and removed and the wafer cell carefully
extracted from the pipe flanges.
97
Laser Spectrometer GPro 500
WARNING
Before removing the probe or wafer cell from the process it is very important to verify with the plant manager
that it is safe. The process must be shut down or in a state
so it is safe to expose the ambient environment to it.
WARNING
Do not turn off the purging before removing the probe.
This will prevent the optical surfaces from being contaminated
7.3.3 Removing & cleaning the corner cube
To remove the corner cube you need to unscrew the end cap on the probe. Thereafter the unit
containing the corner cube can be taken out. Carefully clean the surface of the corner cube and
remount it. The optical surface can be cleaned with non-hazardous, non-abrasive detergents or
solvents. Iso-propyl alcohol (IPA) is the recommended solvent for optical component cleaning.
1
2
Figure 60 Cleaning/Replacing the corner cube on standard probe (SP) and non-purged probe
(NP).
1 Corner cube module
2 Probe end cap
As the in-line wafer cells is integral of the process and in order to maintain the integrity of the PED
(Pressure Equipment Directive) certification, the corner cube should not be removed.
7.3.4 Cleaning the probe process window
To clean the process window you need to remove the probe from the process, see 7.3.2 on page
no 97. Remove the sensor head, unscrew the probe and then unscrew the purging tube with
holder. Carefully clean the surface of the process window. The optical surface can be cleaned
with non-hazardous, non-abrasive detergents or solvents. Iso-propyl alcohol (IPA) is the recommended solvent for optical component cleaning.
WARNING
Do not remove the process window from the window module since that will void the pressure certificate.
98
The process side purge connection is fitted with a seal between the fitting and the purge h ousing
to conform to the pressurized equipment directive (PED). To ensure the integrity of this seal and
to prevent damage when connecting the purge tube to the fitting, a back spanner (wrench) must
be used to securely hold the fitting body as the purge pipe nut is tightened, as illustrated in Figure
61 below.
Figure 61 Connecting purge pipe to process side purge fitting.
WARNING
Do not remove and / or disassemble the purge gas inlet for process (7).
If disassembled, the PED pressure certificate is void.

WARNING
The high pressure glass in the probe must not be subject to any
mechanical impact which might cause damage to the glass (scratch,
gash etc.). When cleaning the glass it must be done with a soft cloth.
Make sure that it is safe to dismount the probe before cleaning.
If the process window cannot be cleaned correctly, the whole window module and flange assembly need to be replaced.
WARNING
The window module 3 is securely attached to the flange 6 using hex
head screws. Do not attempt to remove or untighten the screws,
as this will void the PED pressure certificate.
WARNING
When reassembling the probe 5, carefully slide the purging tube 4 inside and screw the probe into the flange 6 until the thread is fully seated. This is to ensure the tightness of the purging system inside the probe.
7.4 Calibration
If the GPro 500 is installed together with the M400 transmitter, then the M400 can be used to
perform calibration/verification directly. See section 7.1 for details or refer directly to the M400
manual for further information.
7.4.1 Process Calibration
Calibration directly in the process can be done if the concentration of the gas to be measured is
known and stable. This is very convenient and is done very quickly from the calibration menu on
M400. For details, see the M400 manual on page 67.
7.4.2 Calibration using calibration cells (O2 only)
For O2 analyzers, the optional calibration cell can be used to provide a quick and accurate calibration/validation check. Doing this the TDL (the units head) needs to be removed from the probe.
Then it has to be mounted on the calibration cell according to the illustration below. Before calibration is started new values for path length, temperature and pressure have to be entered on M400.
Then the calibration gas is flowed through the calibration cell and the calibration is done in the
calibration menu of M400.
During calibration with the calibration cell the process is still sealed and
no extra precautions need to be taken.

7.5 Residual Hazards
Despite all precautionary measures taken, residual hazards still remain.
7.5.1 Leaky connections
–– Connections can become loosened through the effects of vibration.
–– The connection between measurement probe and process adaptor is a potential source of
leakage.
The connections between the measurement probe and the process adaptor
must be checked regularly by the user/operator, and kept in full working
condition.
WARNING
Leaky connections can allow process medium to escape to the environment, presenting a hazard for persons and the environment.
7.5.2 Electricity failure
WARNING
In case of electricity failure (releasing of the fuse)
make sure that the mains power is properly disconnected before starting any trouble shouting.
7.5.3 Heat protection
WARNING
The housing is not equipped with heat protection. During operation the
surface of the housing can reach high temperatures and cause burns.
7.5.4 External influences
Objects falling on the housing can damage or destroy the TDL head, or
cause leaks etc.
Lateral forces may damage or destroy the TDL head.

Description of Equipment:
General - The GPro 500 Gas Sensor is an optical instrument designed for continuous in-situ gas monitoring in
stack, pipes, and similar applications. The sensor is based on tunable diode laser absorption spectroscopy
(TDLAS) technology. The GPro 500 Gas Sensor utilizes a single side installation without the need for alignment
to measure the average gas concentration along the line of sight path in the probe. The measuring principle
used is infrared single line absorption spectroscopy, which is based on the fact that each gas has distinct
absorption lines at specific wavelengths. The GPro 500 consists of 3 separate units, the TDL head (which is
explosionproof rated and the subject of this certificate), and the insertion probe which has no electrical
connections, a junction box and the user interface M400 (which are not explosionproof rated). The flange
mounted insertion probes are available in 3 lengths.
Construction - The GPro 500 housing is a coated aluminum enclosure with a bolt on cover and is available
with (1) ½ inch NPT conduit opening.
Ratings - The GPro 500 TDL head contains the laser module with a temperature stabilized diode laser,
collimating optics, the main electronics and data storage. The unit is rated for a maximum of 24 VDC, 5 Watts.
The laser source has a maximum radiation strength of 0.24mW/mm².

Appendix 5 ESD Guidelines
ESD (ElectroStatic Discharge)
ESD is the rapid, spontaneous transfer of electrostatic charge induced by a high electrostatic
field. Electrostatic damage to electronic devices can occur at any point from manufacture to field
service. Damage results from handling the devices in uncontrolled surroundings or when poor
ESD control practices are used. Generally damage is classified as either a catastrophic failure or
a latent defect.
A catastrophic failure means that exposure to an ESD event has caused an electronic device to
stop functioning. Such failures can usually be detected when the device is tested before shipment.
A latent defect, on the other hand, is more difficult to identify. It means that the device has only
been partially degraded from exposure to an ESD event. Latent defects are extremely difficult to
prove or detect using current technology, especially after the device is assembled into a finished
product.
Usually, the charge flows through a spark between two objects at different electrostatic potentials as they approach one another.
It is of utmost importance that ESD protective procedures are used during service in the field. The
components used in GPro 500 have all been protected from ESD through the whole production
chain.
Ground Everything
Effective ESD grounds are of critical importance in any operation, and ESD grounding should be
clearly defined and regularly evaluated. According to the ESD Association Standard ANSI EOS/ESD
all conductors in the environment, including personnel, must be bonded or electrically connected
and attached to a known ground, bringing all ESD protective materials and personnel to the same
electrical potential. This potential can be above a „zero“ voltage ground reference as long as all
items in the system are at the same potential. It is important to note that non-conductors in an
Electrostatic Protected Area (EPA) cannot lose their electrostatic charge by attachment to ground.
ESD guidelines
In many facilities, people are one of the prime generators of static electricity. Therefore, wrist straps
must be used while carrying out maintenance and service on the GPro 500, to keep the person
wearing it connected to ground potential. A wrist strap consists of the cuff that goes around the
person‘s wrist and the ground cord that connects the cuff to the common point ground.
Work Surface
An ESD protective work surface is defined as the work area of a single individual, constructed and
equipped to limit damage to ESD sensitive items. The work surface helps to define a specific work
area in which ESD sensitive devices may be safely handled. The work surface is connected to the
common point ground by a resistance to ground of 106 Ohms to 109 Ohms. This is done by using a soft bench mat, which is connected to ground, on the work surface. All equipment must be
connected to grounded outlets and all personnel must wear wrist straps connected to the bench
mat using a cord.
