Warranty

Defects that fall under warranty

The seller shall undertake to remedy any operational malfunction resulting from a manufactured or material defect within the limits of the provision below.

The seller shall not be liable in the case of a defect caused either by materials supplied by the buyer or by a design imposed by the buyer.

Any warranty is also invalid in the case of damage resulting from normal wear and tear, accident, disaster, misuse, fault or negligence of or by Buyer, causes external to the Products such as, but not limited to, unauthorized repairs or part replacement, electrical power surges, improper storage of the Product, use of the Product in a manner for which it was not designed.

Duration and starting point of the warranty

Unless otherwise stipulated, the warranty period shall have a duration of twelve months from the date of delivery within the meaning of article 6 paragraph 2 of the «ENVIRONNEMENT S.A: 2013 INTERNATIONAL GENERAL TERMS AND CONDITIONS OF SALES», even if the shipment or assembly is postponed for any reason outside the seller's control.

Unless agreed upon by both parties, the repair, modification or replacement of parts during the warranty period will not extend or renew the original equipment warranty period.

Buyer's obligation

In order to file a claim under warranty, the buyer must notify the seller immediately in writing of any defect in the equipment and supply evidence in proof thereof. The buyer must provide the seller with the opportunity to observe and remedy the said defects. In addition, the buyer must not carry out any repairs or have repairs made by a third party without the written agreement of the seller.

The buyer is required to check the equipment as soon as possible upon receipt and acceptance and no later than eight days following receipt. Failing to do so might invalidate any claims made later regarding a declared defect.

Any installation, maintenance, repair, service of the product performed by any person or entity other than seller without seller's prior written approval, or any use of replacement parts not supplied by seller, shall immediately void and cancel all warranties with respect to the affected product.

Exercising the warranty

Once notified of a defect, the seller shall be responsible for remedying the defect at its own expense. The seller, however, reserves the right to modify the mechanisms of the equipment as needed to comply with its obligations.

The work to satisfy the warranty obligation shall be carried out, principally, in the seller's workshop after the buyer has returned the equipment or the defective parts to the seller for the purposes of repair or replacement, whichever the seller deems best.

However, if the nature of the equipment is such that the repair has to be carried out at the location where it was installed, the seller shall only be responsible for the on-site labor costs involved in direct service of the analyzer itself. The buyer is responsible for the cost of any additional measures needed to provide unrestricted access.

The cost of transport of the equipment or the defective parts, as well as the return of the repaired or replaced equipment or part, shall be borne by the buyer. In the case of on-site repair, the buyer shall be responsible for any travelling and accommodation expenses of the seller's representative.

SAFETY GUIDELINES

THIS CHAPTER REFERS TO FRENCH REGULATIONS AND

IS INCLUDED SOLELY FOR THE PURPOSE OF EXAMPLE AND INFORMATION.

FOR OPERATION OF THE ANALYZER OUTSIDE FRENCH TERRITORY, PLEASE REFER TO THE REGULATIONS IN FORCE FOR RADIATION

PROTECTION IN THE COUNTRY IN WHICH IT IS TO BE USED.

RADIATION PROTECTION

SPECIAL INSTRUCTIONS

0.1 WARNING

Radioactive sources are regulated substances, it means that their import, export, providing, transport, handling and elimination are managed by legislative texts: please, refer to local laws.

Equipment, process and work organization must be designed so that the individual and collective professional exposures are maintained as low as it is reasonably possible, below the limits prescribed by regulation


SEPTEMBER 20130–10

SAFETY GUIDELINES

0.2 REMINDER OF PRINCIPAL STATUTORY TECHNICAL PRECAUTIONS

In each establishment where this type of equipment is installed, the employer should designate a person responsible for the nuclear activity to make sure that radiation protection regulations are observed and applied.

This person must be aware of these instructions and draw up special instructions for employees who work with this equipment. A model of the safety measures to be exposed in the measurement system is shown at the end of this document, at paragraph 0.7.

The equipment and work methods and organization shall be designed such that individual or group exposure in a professional context shall be maintained as low as reasonably possible, below the limits defined by law.

Before the source is set into service, it should be inspected. Routine inspections of equipment and of the sealing of sources are also provided for in these regulations.

Each source must be delivered with a certificate from the manufacturer certifying the characteristics of the source, especially that it is a sealed source. A sealed source is a source whose structure is such as to prevent, under normal conditions of use, any dispersion of the radioactive substances into the environment.

When the sealed source is definitively removed from service, the end-used have to yield the source to an authorized organism in his country. If there is no this kind of organism who deals with radioactives wastes, radioactive source shall be return to ENVIRONNEMENT SA, after receive the written agreements from ENVIRONNEMENT SA.

In case of loss or theft of an artificial radionuclide or in case of accident (fortuitous event causing a risk of radiation or contamination delivering an equivalent event dose greater than the equivalent of the maximum permissible dose), the authorized person must inform the government representative of the country where the event took place. Information has to be followed to ENVIRONNEMENT SA.

SAFETY GUIDELINES

0.3 PRESENTATION OF EQUIPMENT

0.3.1 DESCRIPTION

The source is secured in the rotary cylinder which is integrated in the upper block of the Beta gauge.

Figure 0–1 – Beta gauge source holder

A warning label is placed on the front side of the upper block of the receiver.

0.3.2 WARNING LABELS AND SAFETY DEVICES

The source holder is a rotary system. The Carbon 14 source can take two positions, storage and emission.

In the emission position, do not touch exit window (A) with hand.

The source holder cannot be disassembled. This design feature is intended to prevent easy access to the source. In the event of interruption of the measurement, source holder returns back automatically on storage position.

SAFETY GUIDELINES

0.4 RISKS ASSESSMENTS

Measurements of dose rate were taken by the IRSN, French expert of radioprotection. The intensity of emission flow is the same one for each type of source used in the analyzers of particles.

The risks assessment from external exposure is equivalent for the sources.

0.4.1 MEASUREMENTS TO THE DIRECT FLOW

Data are the following ones

Radiations of braking Not considered

Dose rate measurement : Contact (naked source) 350µSv/h

Dose rate measurement : 10cm (naked source) 9µSv/h

Dose rate measurement in the plastic box 0.2µSv/h

Dose rate measurement source into analyzer 0.1µSv/h

There is no consideration of amount body dose because the emitted rays are lower than 23cm of length.

0.4.2 CONTROL OF NO CONTAMINATION

The sources are sealed sources. A control of sealing characteristics and no contamination is carried out by the manufacturer and a certificate of sealed source is joined with each source.

The sources are compliant with ISO2919 classification, they respect C34343 classification



SAFETY GUIDELINES

0.5 RISK ANALYSES

The equivalents of maximum permissible dose laid down by French regulations are given in the here-below table. The values are extracted from the public health laws (Labour and Public Health Rules).

According to the French labour laws, a worker is told exposed if, because of his professional activity, he is submitted to ionizing radiations likely to involve doses superior to the levels presented here-below.

Exposed zone Limit of equivalent dose

Global exposure 1 mSv/ year

Crystalline lens 15 mSv/ year

Skin 50 mSv/ year in average value for any surface of 1cm²

0.5.1 EXTERNAL EXPOSURE

When the analyzer is working, and even when the analyzer is not working, there is no direct access to the source. Under normal conditions of analyzers use, there is no possible irradiation. Indeed, because of the radiation type, there is no possible external exposure for the whole body (radiations have a distance lower than 23cm).

Consequently, the sources handling only occur when the source is put in place into the analyzer, and when the source is put out of the analyzer at the end of the source use.

The sources handling can only be carried out by people qualified and trained to this kind of sources and to their specific dangers. The technician must wear gloves.

For hands, in contact with the window of measurement, we can consider a dose rate of 0, 1µSv/h. To exceed the regulatory threshold of 50000µSv per year, the technician should leave his hands in contact with the window of measurement of the analyzer during more than 500 000 hours per year, which is realistic. Therefore, the values are very much lower than flows of tolerable for the public.

NOTA : to value the received dose, the dosimetric films are inoperative because insensitive to Beta radiations of low energy.

0.5.2 INTERNAL EXPOSURE

The internal exposure corresponds to the ingestion or the inhalation of radioactive materials.

According to the appendices of directive Euratom 96/29, the effective dose engaged by ingestion for the 14C is 5,8.10-10 Sv/Bq. To exceed the threshold of 1 mSv/an (total exposure), it would be necessary to eat one 14C source per year (for source of 1,6MBq)

These situations are obviously completely improbable. In normal condition of use the probability of inhaling radioactive dusts is very low: the sources are sealed into a closed analyzer.

Assessments by French Radioprotection Expert, IRSN, was made, they confirmed that the level of internal exposure is considered negligible and radiation doses are well below regulatory limits.

In normal use, the personnel, using MP101M, is not defined as exposed worker, and is not classified into category A or B. The acceptable exposure values are those valid for the public.

In practice, there is neither protected area (it would be located in contact with the outlet window which is inaccessible), nor controlled area.



SAFETY GUIDELINES

0.6 RADIATION PROTECTION RECOMMENDATIONS

0.6.1 SIGNALS

A label indicating the presence of a radioactive source can be put outside on the analyzer door. In this case, it is necessary to use the black radioactive clover on yellow background. To take care not to use other types of clover.

Figure 0–3 – Radioactive clover

A warning label is placed on the front side of the upper block of the receiver.

0.6.2 STAFF INFORMATION

The staff of the user company should be clearly informed of the presence of the radioactive source, of the associated risks, and of the meaning of various signals.

0.6.3 INTERVENTION ON SOURCE HOLDERS

Any intervention on source holders should be made by the supplier or under the authority of the person responsible for the nuclear activity of the user company by an person aware of the risks.

0.6.4 ESTIMATES OF SPECIAL RISKS

The person responsible for the nuclear activity should draw up the miscellaneous instructions to be applied in case of malfunctions, incidents or fires, providing for the measures to be taken and the interventions to be carried out.

In case of a fire likely to affect the confinement of the sealed source, the risk of surface and atmospheric contamination would be low in light of the activity applicable in this case.

1.1. GENERAL

1.1.1. PRESENTATION (FIGURE 1–1)

The MP101M system is used to measure suspended particulate matter in the ambient air. Sampled air can also be monitored continuously for possible natural radioactivity, with programmed alarm in the event of a threshold overshoot.

The system is available in the form of an indoor cabinet for installation in a closed room, or an outdoor, heated and ventilated enclosure. This monitor can operate separately or be included into supervision and warning networks.

The MP101M is a particles measuring device using Beta gauge. The suspended particles are gathered by sampling a defined volume of air on a glass fiber filter. The filter is automatically unrolled between the Beta source and a Geiger-Müller counter (GM) according to defined sequences.

The difference in the radiation counting before and after gathering of the particles represents the measurement of the mass on the filter. Sampling is carried out with a vacuum pump through a sampling head connected to the top of the analyzer.

The MP101M provides many advantages, due to its technical design:

flexibility in use due to the multitasks interactive software,

presence of an upgradeable ARM7 board.

The Carbon 14 (14C) radioelement contained in the source has low-intensity and a long half-life of about 5730 years.

The filter ribbon used allows for a high number of sampling events (1200).

By the high-reliability of its components and its ease of use, the MP101M requires very limited maintenance.

Its surface density is determined in laboratory by gravimetric weighing.

The reference gauge is used for calibrating and checking the Beta gauge.

– The filter ribbon drive system, comprising:

a pay-out reel (10),

a take-up reel (7),

a capstan (5) coupled to the synchronous feed motor,

a disengageable pinch roller (6).

– The Beta gauge

The Beta gauge consists of a Carbon 14 radioactive source (14C) located in a source holder (3) in which the source can take two positions: – Out of the channel, when system is drawing in air (sampling) or shut down, – In front of the Geiger counter, for measurements of beta particles.

Geiger-Müller tube detector (8), located on the same axis, downstream of the ribbon.

In measurement mode, the source and G.M counter always maintain the same relative positions regardless of the operations performed on the device (translation of pressure assembly, ribbon feed, positioning of a reference gauge) in order to ensure the same counting conditions in all cases.

– Gas transport system

A flexible channel (4) with knurled knob for connection of the sampling head.

The flexible channel can be retracted for installation of a fixed head,

or unscrewed for use of a telescopic head.

A 16 mm diameter cylindrical conduit made of stainless steel. This conduit channels the gases sampled to the glass fibre filter (filter ribbon) with no obstacles, thus ensuring uniformity of the particle deposit.

A pressure assembly (9), maintaining the filter against the source block during measurements. Tightness of the system is ensured by the pressure assembly (9) and a clamping grille located above the G.M counter.

Heating system

The housing is heated by a 500 W electrical resistor coupled to one of the fans. The temperature is regulated by a thermostat (range: 0 to 30 °C) associated to a safety switch (cut-out at 60 °C).

1.2.4.2. Installation

a) Installation outdoors

a.1) Concrete base

For outdoor installation of the sealed box, a concrete slab (2 m x 1 m) is required.

The minimum height of the base (to protect it against water) will be selected according to the field conditions.

A passage must be provided in the base for the electrical power supply and for other cables which may be required for remote control, telephone link, etc.

Four diameter M10 threaded rods protruding by 0.10 m must be embedded in the concrete slab to receive the stainless steel legs on which the housing is mounted.

a.2) Installing the MP101M

The MP101M is set on the aluminium base plate and blocked by inserting the studs of the rear legs into the holes provided for this purpose on the mounting plate.



a.3) Installing the regulated sampling tube (RST)

Place the sampling head in its housing and adjust the height to ensure tightness between the head channel and the channel of the MP101M, without crushing it (see diagram below).

2.1. BETA GAUGE PRINCIPLE (FIGURE 2–1 AND FIGURE 2–2)

A BETA gauge consists of a radioactive source of Carbon 14 (14C) radioelement, emitting soft Beta radiation and a radioactive radiation detector: Geiger-Müller (G.M.) tube. The G.M. is mounted at a given distance downstream of the filter ribbon which gathers the particles suspended in the air.

Figure 2–2 – Beta gauge

When determining a mass deposit, at the end of each period or cycle, the source is aligned with the dust deposit and the counter (G.M.).

The low-energy Beta rays are absorbed by the matter by collision with the electrons whose number will be proportional to the density.

The matter consists of the glass fibre filter, the dust deposited and the air between the source and the G.M.

The absorption is governed by an exponential law and is independent of the physico-chemical nature of the matter.

The measurement consists in calculating the difference in absorption observed on the blank filter at the start of the cycle and on the charged filter at the end of the period or cycle.

This differential measurement is used to compensate for the non-uniformity of the filter when calculating the mass of the deposited dust. The monitor also compensates for the variation in temperature of the weight of the air knife.


SEPTEMBER 20132–4

The measurement method is governed by the following relations:

a) Blank filter at start of cycle

N1 = N0 e -k (m0 + m1)

N0 Count without absorbent (see Remark)

N1 Corrected count, in counts per second, on blank filter (air + filter) (see NOTE)

m0 Density of blank filter (mg/cm2)

m1 Density of air (mg/cm2) at temperature T1

NOTE : As concerns N1 and N2 (see below): the corrected value N displayed by the unit is deduced from the non-corrected value N' as a function of the dead time of the counter tube (G.M.) by the formula:

N = N'

1 - N' 11

The density of the air (m1) contained in the volume V between the source and the detector is deduced from the temperature of the air knife (T1) measured at the start of the cycle, using the following relation:

Remark: The activity of the source does not affect the measurement of the density deposited since the magnitude N0 characterizing it disappears when N1/N2 is resolved. The time interval separating the blank filter measurement is negligible with respect to the period of the radio element used (5730 years).

SEPTEMBER 20132–6

2.2. FLOW REGULATION PRINCIPLE

The sample is taken at a constant volume flow rate with compensation of load loss due to the filter and progressive depositing of dust.

The flow rate is therefore controlled and maintained at the selected reference value of 1.0 m3/h.

P1 and P2 designate the absolute static pressures measured on both sides of the diaphragm through two axial holes perpendicular to the fluid flow direction and located very near the diaphragm.

The diaphragm is machined and arranged to produce a turbulent flow in the immediate vicinity. The

diameters of the conduit and orifice are sized such that, P

> 0.9 in most cases, whereby the flow

can be considered as incompressible, minimizing load loss effects.


2–7SEPTEMBER 2013

The internal sensors of temperature and pressure coupled with the meterological sensors of regulated sampling tube (RST) line enable to measure the “volumetric” flow rate in the atmospheric conditions:

The flow rate is thus controlled and maintained constant to the nominal setting value (1 m3/h) at level of sampling head. That is essential in order to ensure the correct granulometric separation of the particles through the head and the precise calculation of sampled volume in atmospheric conditions.

The flow of a fluid through a critical orifice is given by the following equation, in case of an homogenous, not turbulent flow :

2.3. ACQUISITION AND PROCESSING OF MEASUREMENT PARAMETERS

The temperature and pressure sensor outputs are transmitted via an analog multiplexer with 16 input channels to the D/A converter on the Module board (4) in figure 1–7. The signals are converted into digital signals and sent to the microprocessor.

The microprocessor processes acquisition data, carries out calculations, automatisms, interfaces control.

The microprocessor receives the digital signal corresponding to count of the (G.M.) detection tube.

2.4. ORGANIZATION OF MEASUREMENTS

The measurements are organized into scan periods and cycles. A scan period is the time between two intermediate weightings performed during a cycle.

Two types of measurement results are thus generated: periodic and/or cyclic.

a) Cyclic

This type of measurement provides better precision. The cycle duration is selected to obtain maximum density of dust deposited on the filter (this depends on the utilization site).

b) Periodic

This type of measurement is less precise than a cyclic measurement. The periodic measurement is used to analyze the density of the dust while it is being deposited in order to monitor a rapidly evolving pollution event.

When operating with both cycle and period, both types of measurements are expressed. This operating mode is preferable since, unlike operation with the "short" cycle, a substantial amount of filter ribbon will be saved since the ribbon is only normally fed forward at the start of the cycle.

c) Filter clogging condition

During a cycle, it is possible that the filter ribbon be advanced several times if a clogging condition is detected. Clogging is detected when the pressure P1 is below the threshold value (factory parameter) indicating that the flow can no longer be regulated. When a clogging condition occurs, the "running" cycle is interrupted, the average of the partial concentration is calculated, the paper is advanced and the "running" cycle is resumed following a new reference calibration on the "blank" filter paper. The average concentration of the cycle will then be computed using the overall partial concentrations stored. N represents the number of spots used during the cycle and Ck the average concentrations on a fraction of a cycle corresponding to the spot at row k. At the end of the cycle, the analyzer computes the average cyclic concentration:

CCM = 1

N k = 1

N

Ck

d) Floating average

It is an average concerning the periodic concentrations delivered by the beta gauge. Its integration duration and its calculation step are programmable.

Example of a running average for 24 hours, and whose time step is 1h: every hour, the system calculates the average of the periodic measurements delivered during the last 24 hours. Thus, in case of a period duration equal to 2 hours, the running average is the result of the average of the 12 last periods.

e) Average concentration

The average concentration is calculated as follow :

If the MP101M is configured to operate in cycles and periods, it is possible to display on the screen (as additional information), the value of the cumulated concentration at the end of every scanning period. This value is calculated as the averages of the intermediate concentrations from t0 to t1, from t0 to t2, from t0 to tn until the end of the cycle.

The value of the cumulated concentration is an additional information that can only be displayed and instantaneously removed via a « data logger », if the analyzer was correctly configured.

f) Dew point

The dew point or dew temperature is a thermodynamic data specific of gas humidity. The dew point of air is the temperature to which the partial pressure of vapour is equal to its pressure of saturated vapour. If the humid air is gradually cooled, the dew temperature corresponds to the generation of water under liquid phase. This phenomenon is the measurement principle used in the condensation hygrometers, which is also called dew point hygrometers.

It is the phenomenon of condensation, which occurs when the dew point is reached and the nucleation sites are available, which generates clouds, fog and dew in meteorology. Condensation is generated, in the same manner on the walls of the buildings.

When the temperature is lower than the freezing point, the air can become saturated with water and generate superfused droplets, or saturated with ice and give white frost. In this second case, the saturation temperature is named icing point. This icing point is warmer than the dew point at these temperatures because the pressure of saturating vapour compared to the ice is lower than compared to liquid water. It is the reason why the vapour more generally settles into solid form than liquid form under the condensation point.



NOTE : The concept of dew point is an important basis concept about the operation of cooling dryers of compressed air.

Calculation methods : Magnus-Tetens Formula

Field of validity:

T : measured temperature : 0° C < T < 60 °C*0.15

RH Relative humidity : 0,01 < RH < 1,00 (step, stated in percentage)

Td : dew point : 0° C < Td < 50° C

With :

a = 17,27 and b=237,7 [°C]

2.5. REGULATED SAMPLING TUBE (RST)

The regulated sampling tube (RST) line fulfils the requirements of the standards relating to sampling and measurement of suspended particles PM10 (EN 12341) and PM2.5 (EN 14907). The method of particles sampling on filter must be equivalent to the reference method. Consequently, sampling must be carried out at a temperature close to the ambient temperature, in order to avoid any phenomenon of condensation inside the sampling line and any loss of weight due to the volatile and semi volatile compounds (as ammonium nitrate) which pass into gaseous phase at about 40 °C.

The regulated sampling tube (RST) line (Figure 2–5) is composed of :

A duct tube of 20 mm diameter (1).

A protection sheath of 60 mm external diameter (2).

A heating cord which surrounds the duct tube (3).

A temperature sensor located on the duct tube (4).

An outside meterological sensor (5) with an atmospheric temperature sensor (5-2) and a probe of relative humidity (5-1).

An adapter (6) for any standard sampling head (TSP, PM10, PM2.5, PM1, US or EN).

An electrical connector (7) to connect line heating,

A DB15 connector (8) to transfer temperature and moisture signals.



Figure 2–5 – Regulated sampling tube (RST) line assembly



The sampling temperature control is managed by the software of the device in the following way:

Sampling is carried out at atmospheric temperature.

A continuous measurement of external relative humidity is carried out,

When the RH value exceeds the empirical threshold of 60%, the line is heated and controlled (with a PID standard integration) at a temperature equal to the atmospheric temperature + 5 °C, in order to avoid condensation inside the line.

T head = T atmospheric + 5 °C.

To carry out calibration, press down the [>>] key to return to the previous screen, and the [Auto] key to launch the automatic calibration of flow rate. The « Calibration cycle » screen shown below is displayed.



Press down the [Start] key to start the calibration.

This screen enables the user to monitor the phases sequence with the « > » cursor : the device enters into « Initialization » phase, the filter paper is fed for one step, and the pressure plate is placed in the up position, against the filter paper. Then, the pump starts: the device passes into « Calibration » phase, the « Reference » flow rate, preset, is displayed, as well as the measured « Flow rate ».

If the difference between both these values is higher than 1,5 l/min, the calibration is wrong, the instrument must be re-calibrated.

– To do that, connect a reference flow meter to the flexible channel, and press down the [Details] key: the « Calibration details » screen with all the calculation parameters is displayed.

NOTE : The flexible channel is described in Chapter 1, section Gas transport system, page 1-6 , and shown in (4) of figure 1-4.



Pressure fields :

P1 field: pressure value upstream the critical orifice,

P2 field: pressure value downstream the critical orifice,

Atm. field: atmospheric pressure.

Temperature fields :

Filter field : temperature at filter level,

Atm. field: external temperature measured by the meteo sensor (if the meteo sensor option is available).

Flow-rate fields: flow-rate parameters for the current measurement.

Automatic calculation of the flow rate coefficient :

Procedure: it consists in inputting the flow rate values given by the reference flow meter

connected to the analyzer, then to validate this value with the [ ] key. The instrument automatically modifies the flow rate F coefficient, and displays the new flow rate value measured by the analyzer, which is obtained with the new coefficient.

Operating mode :

Using the [] key, go to « Calibration » line, then press down the [] key to activate the input field of the flow rate value read on the reference flow meter connected to the instrument.

Using the [], [] and [] keys, input the flow rate value, stated in l/min, read on the flow

meter. Validate the input with the F6 [ ] key.

Then, the instrument calculates the flow rate span coefficient. : and « F Coef. » is displayed in the corresponding field.

Validate the calculated coefficient by pressing down the [Memo] key the new F Coef. is memorized, its value is updated, and the flow rate measurement is adjusted to the reference value.



If the span flow rate does not correspond to the flow rate measured by the instrument (difference > 1,5 l/min), repeat the calibration procedure.

Quit the display by pressing down the [] key, then the [Stop] key.

REMARK : The flow value read on the reference flowmeter is valid for a defined reference temperature Tref and a reference pressure Pref = 1013 hPa.

Thus, it is necessary to convert this flow for the conditions Tatm and Patm in order to compare it with the flow indicated by the analyzer.

3.3.4.6 CONFIGURATION Communications Serial link

This screen is used to configure the Serial link (COM 1). The address, the baud rate, the format, and the communication protocol are configurable :

The analyzer address is composed of 4 characters which define the device code for remote controlling, or when the device is integrated into a network.

The speed of communication of the serial link is stated as the baud rate (bits per seconds): 1200, 2400, 4800, 9600, 19200, 38400, (limited to 19200 bds at present time).

The data transmission format is selected from the following: 7,n,1; 7,o,1; 7,e,1; 7,n,2; 7,o,2; 7,e,2; 8,n,1; 8,o,1; 8,e,1; 8,n,2; 8,o,2; or 8,e,2. This is a common shorthand notation for a serial port parameter setting in asynchronous mode. The first character is the number of data bits (can be 7 or 8). The second character is the parity control (can be n (for non), e (for even), or o (for odd)). The third character is the number of stop bits (can be 1 or 2).

Examples: 8,n,1: 8 data bits, no parity bit, 1 stop bit

8,o,1: 8 data bits, 1 odd parity bit, 1 stop bit

8,e,2: 8 data bits, 1even parity bit, 2 stop bits

Communication protocol: Mode 4,JBUS, PRN.

Mode4 is a communication protocol proper to Environnement SA, designed to send and receive data. It works according to master/slave mode.

JBUS protocol is an industrial protocol designed to dialog with automatons. It works according to master/slave mode.

PRN protocol is a text data frame containing information about the measures (compound name, value, unit) of the analyzer and automatically transmitted, without request, at programmable intervals.

Interface : RS-232 or RS-422.

These are standards of communication interfaces. RS-422 enables multipoint communication management for industrial controllers and RS-232 enables point-to-point communication management: analyzer PC.



3.3.4.7 CONFIGURATION Communication Network configuration

To establish the communication between a local network and the analyzer it is necessary to configure an IP (Internet Protocol) address and a subnet mask that can be recognized by this analyzer.

For example if your PC uses the IP address 192.168.0.20 and the Subnet mask 255.255.0.0 it can only communicate with an analyzer that uses an IP address of the shape 192.168.x.x and the mask 255.255.0.0

This screen is used to configure the IP address and Mask of the analyzer:

HostName field: name of the analyzer to be recognized on the network (can not be changed by the user).

IP address field: enter an IP address that enables the communication between the analyzer and the computer.

Mask field: enter a mask that enables the communication between the analyzer and the computer.

Mac address field: physical address of the analyzer named Medium Access control (can not be changed by the user).

After any modification, go to the Validate field and switch it to ON.



3.3.4.8 CONFIGURATION Communication UDP server

UDP stands for User Datagram Protocol. The analyzer network communication runs only under this protocol.

UDP applications use datagram sockets to establish host-to-host communications.

These sockets bind the application to service ports that function as the endpoints of the data transmission. A port is a software structure that is identified by a port number. Two different ports can be bind to the analyzer: Port A and Port B. They are identified by two different corresponding port numbers (8003 and 8001 for example).

Port fields : the numbers of Port A and Port B of the UDP server are programmable from 1000 to 9999

Address fields : they are programmable with 4 characters, the analyzer’s name is used by default.

Protocole fields: the user can choose different types of protocols: Mode4, JBUS, and PRN. In the last case (PRN), the IP address of the computer has to be entered.

Scope : Verification of pressure exerted on the filter PAGE : 2/2 Periodicity : 1 year

Dates

8/ Check that the filter ribbon does not move while the capstan is turning. If this is the case, then the pressure on the ribbon is correct.

If the filter ribbon moves while the capstan is turning, then adjustments need to be made to the take-up reel and/or the pay-out reel until the filter ribbon no longer moves.

Note that adjustment of the pay-out reel pressure may be more important than that of the take-up reel.

Example :

– If the filter ribbon is observed to be overly strained and damaged, then a likely cause may the tension on the pay-out reel.

– To correct this behavior, open the cover of the analyzer, loosen the clutch of the pay-out reel using the knurled button and spring, and repeat the filter ribbon pressure test and reel adjustment until satisfactory results are obtained.

9/ Remove the paper located between the capstan and the ribbon.

Specific configuration for 0–5 volt output instead of 0–10 volts

Four possible configurations allow for output of 0–5 volts:

Board configured for 0–10 volts with addition of a divider (by 2) bridge:

The user carries out the operation when specifying the acquisition system.

Operating mode: connect each analog output, previously configured for 0–10 volts, to ground through two resistances of equal value within 500 and 1000 Ohms.

Remove the “divide by 2” signal at the terminals of resistance that are connected to the ground.

0-10 V

GroundR

R0-5 V

R = 500 ohms

Board configured for 0–10 volts with adjustment of half gain:

In menu « Tests ESTEL boards », adjust the A and B coefficients of each channel in order to obtain 0–5 V at analog output for an analog-to-digital converter resolution fo 0–4000 points.

Board configured for 0–20 MA

Output of the acquisition system is carried out by the user.

Operating mode:

Connect each analog output, previously configured for 0–20 mA, to ground using a resistance of 250 Ohms, tolerance 1 %.

Voltage generated in this manner is equal to UmV = 250 x ImA, that is to say 5 V for I = 20 mA.

NOTE : – Place resistance to the nearest possible receiving equipment.

ImA : is the intensity of the electric current in milliamp.

I : is the intensity of the electric current.

Modification of gain resistance on ESTEL board

Carried out by the manufacturer if other solutions suggested to the user fail.


JUNE 20098

1.4 PROGRAMMING

The analyzer automatically detects the presence of one or two ESTEL boards and provides menus that let the user adjust and configure each board. ESTEL board programming and configuration is carried out from the « ESTEL card(s) » menu of the « Carte(s) I2C » screen.

To access the various screens of the ESTEL board, select the desired function in the « Function » field using the up [ ] and down [ ] keys.


JUNE 2009 9

1.4.1 ESTEL CARD(S) Analog output

This screen lets the user assign parameters to the analog outputs for the ESTEL board whose number is highlighted in the « No » field. These parameters are as follows:

Concentration of analyzed gases

Auxiliary channels (multiplexer)

Analog inputs

Analog outputs on an ESTEL board can be configured for 0–1 volt, 0–10 volts, 0–20 mA, and 4–20 mA. These four ranges correspond to the full scale of the analog output, and the units are those of the parameters displayed in the « Signal » column. When the signal value is higher than the full scale of the current range, the analyzer switches to the next higher range. It switches back to the lower range when measurement again falls below 85%. When the user assigns several measurement ranges to only one analog output, the metrological resolution can be changed as shown below. To avoid range switching, the user must assign the same value to the four ranges of the parameter that will be sent as analog output.
