2 Safety instructions

Safety instructions and warnings are provided at the points in the respective chapters where the information is required. Some warnings are also provided repeatedly for this reason, to ensure that the potential danger arising from a given situation is always highlighted. Always observe and comply with the sa-fety instructions, caution notes and warnings provided in the chapters. Also observe the following warnings and safety instructions. They serve to a-vert dangers to life and limb of users and maintenance personnel and to prevent damage to property. They apply for all measures and tasks described in this manual, even if they are not explicitly indicated again at the relevant point.

2.1 General

WARNING Only operate the measuring device D−R 820 F in perfect condition and in strict compliance with the safety instructions!

• The Dust Concentration Meter D−R 820 F may only be connected to the

supply voltage shown on the typeplate (standard: 400V, 3~, 50Hz). • The D−R 820 F may only be operated on a power supply with an earthing

contact. The protective action must not be cancelled by an extension with-out an earthing contact. Any interruption in the protective earth conductor inside or outside the device is dangerous and is not permitted.

• The D−R 820 F must be protected with a 16 A fuse on the input side. • Before opening any device components, the Dust Concentration Meter

D−R 820 F must be disconnected from the power supply by operating the main switch or the series fuse.

• Electronic components are becoming ever smaller and more complex. As a result, their susceptibility to electrostatic discharge is also increasing. Mod-ern electronic components are very sensitive to electrostatic discharge. To protect these components, measures must be taken against electrostatic discharges (ESD protection) when performing any work on the open de-vice. To prevent static charging of the human body, we recommend that service personnel are equipped with a personal grounding system.

• Use of the D−R 820 F in potentially explosive areas and measurement in explosive gas mixtures is not permitted.

• Cables and gas lines should be laid so that risk of accident due to tripping or getting caught on the lines is excluded.

• Parts of the probe are electrically heated or come into contact with hot measuring gas and are therefore subject to high temperatures. Never touch these parts without temperature-resistant gloves or when the parts are live.

• The measuring system as a whole, as well as the individual components, may only be operated in the original design. If elements are replaced, the manufacturer's genuine parts must be used.

• Modifications to the configuration of the measuring system, i.e. the adjust-ment of parameters which are not normally available to the user, can com-promise the safety of the Dust Concentration Meter and are carried out at own risk! Therefore, have configuration modifications carried out by an authorised service technician or by the manufacturer's factory personnel.

Safety instructions

18 D−R 820 F

• Covers inside the D−R 820 F may only be removed when the system is disconnected from the power supply.

• Subassemblies are configured device-specifically and are therefore not in-terchangeable between different D−R 820 F.

WARNING Installation, operation, maintenance activities and any repairs must be per-formed exclusively by qualified personnel of the manufacturer, taking account of the pertinent requirements (Zentralverband der Elektrotechnik- und Elektro-industrie e.V./Central Association of the Electrical Engineering and Electronics Industry).

2.2 Blower

2.2.1 Suction action Warning: Objects, articles of clothing and even hair can be sucked in (risk of injury!). Do not stand near the suction intake during operation. Never operate the blo-wer with the suction intake open. This must be covered with an air filter with fi-ne filter cartridge. Do not reach into the suction intake.

2.2.2 Blow-out action Warning: Very strong blow-out action at the discharge nozzle. Sucked-in ob-jects can be ejected at high speed (risk of injury!). The blower is only suitable for conveying clean air. Foreign bodies or impuri-ties that could be blown out must be filtered out before entry into the blower. The blower must never be operated with the discharge nozzle open and must therefore be covered with a guard in accordance with DIN EN 294. Do not reach into the discharge hole.

2.2.3 Temperature Warning: The blower housing heats up during operation. If the temperature exceeds + 50°C, the blower must be protected from direct contact by the op-erator (risk of burns!).

2.2.4 Noise development The noises emitted by the blower vary in the range up to approx. 80 dB(A) sound-pressure level LA. In certain unfavourable cases, sound insulation is required (measurements by the operator recommended). The operator must provide this sound insulation to prevent exceeding of the legally permitted maximum values at workstations in the blower environment.

Product Description

D−R 820 F 33

The Dust Concentration Meter D−R 820 F is a highly sensitive system for con-tinuous, optical, extractive dust or dust concentration measurement. A defined partial current is removed from the exhaust gas current. This partial current is continuously heated and diluted with clean, tempered ambient air. The partial current is optically measured in the measuring chamber. The signal that results from the diverted current is a measurement of the dust content of the exhaust gas. The microcontroller integrated into the control unit generates a dust-proportional signal. This is output as a 4 ... 20 mA signal. In addition, the cur-rent measured value is displayed on the control unit display. Various parame-ters (e.g. relating to the display) can be entered and adjusted using the key-board.

Figure 3.11: D−R 820 F Functional diagram with 2 blowers

The D−R 820 F can alternatively be operated with compressed air or nitrogen. These can also be used to cool the probe housing. This can be seen in a vari-ant of the functional diagram Figure 3.12.

3.8.1.2 Functional diagram of the optical probe The optical probe of the D−R 820 F operates according to the forward scatter-ing principle. The concentrated and modulated light of a laser diode penetrates the measuring volume. The light scattered by the dust particles is largely scat-tered forwards, therefore the receiving lens is positioned here. The scattered light is generated in proportion to the dust concentration pre-sent, so the more dust, the more scattered light. The light is guided by an opti-cal waveguide to the receiving diode, where it is processed to the desired end size by a sensitive electronic unit. The obtained measuring result is calibrat-able and can, in accordance with directive EN 13284-1, be displayed on the dust concentration in mg/m³.

For the automatic function test and the legal control cycle, a beam splitter with a shutter has been used inside the electronic housing in this system. It swit-

ches between the actual optical measurement and the comparison path. Con-sequently, there are no moving parts in the corrosive exhaust gas. This also ensures that the termination between optical probe and electronic housing is gas-tight. The basic calibration of the system can be carried out by software. A pollution measurement is performed every 5 min in order to record dust de-posits on the optical boundary surfaces and the ageing of the optical elements.

3.8.1.3 Extractive dust measurement In the case of the D−R 820 F, another mathematical relationship results be-tween the physical values in relation to the optical in-situ measurement (see also chapter 3.8.1 Measuring principle from page 34). The optical signal Cal (scattered light) is dependent on the dust content of the measuring gas, the set dilution of the extracted measuring gas, the temperatures and absolute pres-sures of the gases. The mathematical relationship therefore appears as follows:

(Indices: "without" measuring chamber, "D" diluting air and "M" measuring gas) The relationship with the measuring gas results from:

FM Extracted measuring gas volume flow [m³/h]

F Volume flow in the measuring chamber [m³/h] DM FFF −≈

FD Volume flow diluting air [m³/h] A contamination-related decrease in the volume flow and an environment-related temperature change are corrected with this correction. The absolute pressures and TM are preset as constants! The D−R 820 F outputs the dust-proportional signal CiB on the display and at the analog output (4 ... 20 mA). CiB then corresponds to the above-specified relationship. In addition, the cal signal (scattered light) is always provided via an analog output. The unit [V] for the cal signal was defined during the development of the Dust Concentration Meter D−R 820 F. The two parameters for gravimetric correction of the dust signal A and D are preset at delivery. A and D are determined during a gravimetric comparison measurement and can be stored in the control unit. Default setting: A = 1 D = 0 (see chapter 8.2 Dust calibration page 79)

3.8.2 Gas ducts The course of the measuring gas can be seen in Figure 3.13. The D−R 820 F continuously samples a partial current from the exhaust gas (suction is per-formed by an injector). As the measuring gas usually contains a strong con-centration of the particles to be measured, a defined (heated) diluting air cur-rent is added to the extracted partial gas current at the probe input of the D−R 820 F (see 3.8.3 Thinning, dilution page 38) , i.e. the measuring gas is di-luted to a defined extent. At the same time, the gas mixture is heated up to a set temperature (see 11.2 Presetting page 100), at which the moisture is evaporated, but the particles to be measured are present in solid state. This extracted, diluted and heated measuring gas then passes the measuring cell and then leaves the measuring device. The course of the measuring gas can be seen in Figure 3.13.

For diagnostic and cleaning purposes, the D−R 820 F automatically executes a purge operation. This includes a zero and reference point control (see 3.8.3 Thinning, dilution page 38) and cleaning of the ducts that conduct the measur-ing gas (see 3.8.5 3/2-way ball valve page 39). The purge operation is illus-trated in Figure 3.14.

3.8.4 Zero and reference point To guarantee a precise measurement, the D−R 820 F performs an automatic zero and reference point control every 4 hours (default value, starting with switch-on). First of all the current zero point of the sensor is checked. This is followed by checking of the pollution and then the reference value of the sen-sor, in comparison with the calibrated reference value (see chapter 8 Calibration page 79). In this way the sensor is checked for correct functioning. If the deviations are too large, this indicates a maintenance requirement or a fault (see chapter 10 Error messages and error elimination page 91).

3.8.5 3/2-way ball valve For self-diagnosis and cleaning of the probe's measuring gas-conducting ele-ments, the 3/2-way ball valve and the purge valve are set to the purge position every 24 hours (default value), so that the probe is cleaned. Ball valve and purge valve are actuated automatically. This cleaning procedure is also executed when a fault is detected in the ( ) extractive Dust Concentration Meter D−R 820 F, in order to protect the measuring device from heavy pollution. The volume flows and temperatures are monitored with the aid of the preset parameters. Further internal tests are also carried out on the measuring device to check correct functioning (e.g. in-ternal memory, communication sensor - control unit, sensor temperature) The ball valve can also be operated manually for diagnostic purposes. For this purpose it is possible to change between PURGE and MEASURING with the

and keys on the control unit of the D−R 820 F. Alternatively, the rotary switch on the ball valve can also be operated manu-ally. For this purpose the Automatic/Manual adjusting hand wheel on the left side of the ball valve must be set to MANUAL (the ball valve must be reset af-ter completing the diagnosis or maintenance activity).

CAUTION For continuous dust measurement, the Automatic/Manual adjusting handwheel must be in the AUTOMATIC position!

After switching from purge to measurement, the D−R 820 F remains in Pur-ge/Maintenance status for another minute!

If the D−R 820 F is in fault status, the ball valve cannot be moved into the measurement position!

4.1 Selection of the measuring point The installation position of the probe should meet the requirements of the gui-delines applicable in-situ (e.g. EN 13284-1) (in Germany VDI 2066 page 1). In case of doubt, we recommend that the installation position is determined by the responsible measuring institute (measuring point in accordance with §§ 26/28 ( ) BImSchG/Federal Immission Control Act). We recommend that the inlet and outlet section is at least 5 x diameter of the exhaust gas channel.

In principle it should be noted that the dust and flue gas distribution must be as homogeneous as possible at the measuring point, in order to obtain a repre-sentative recording of the dust load across the duct cross-section.

4.2 Installation of the weld-in socket The weld-in socket of the D−R 820 F is installed in accordance with Figure 4.2 or Figure 4.3 . The installation position of the probe is horizontal. As a rule the D−R 820 F is arranged with a sample gas recirculation. An acci-dental blocking of the outgoing air with the risk of strong contamination of lenses and filter, will thus be prevented. Figure 4.2 and Figure 4.3 are showing how to handle the sample gas recirculation. A separate routeing of the outgoing air with additional return nozzle to the stack or a direct recirculation (>10 m!) to the mounting flange is expedient.

In principle the sample gas recirculation could take place back into the room, because it is a matter of highly diluted (injector and diluting air) stack gas. But this gas has a lot of heat energy and will warm-up the room. A recirculation out-of-doors is more suitable. In either case it should be seen that the hose is correctly laid to prevent a blocking. The sample gas leaves the probe with a temperature of over 70° C. By com-pliance with the max. length of hose (10 m), there is no probability that the hose would freeze.

The mounting of the weld-in socket on the measuring channel has to carry the weight of the socket (approx. 10 kg) and the weight of the complete probe (approx. 60 kg). If necessary the channel has to be strengthened by a support-ing structure.

Assembly

D−R 820 F 45

4.3 Installation of the probe Danger of contamination of the measuring cell!

For mounting and during the time up to commissioning the ball valve has to be set to MANUAL and PURGE!

For mounting the probe it is recommended to do the following steps: 1. Set the ball valve to MANUAL and PURGE, 2. remove optical sensor while mounting (unfasten 4 nuts, separate screwed

cable gland and remove sensor), 3. insert probe into flange (don’t forget gasket!), 4. tighten probe with the 4 nuts and bolts provided,

(Installation position as in picture: angle plug on the left towards the center of the D−R 820 F unit).

5. reinsert optical sensor, 6. set check valve vertically (purge air optical sensor),

Flow arrow of valve points upwards (to optical sensor).

Always pay attention that the check valve, above the purge air filter of optical sensor, is in an upright position. (see „R“ in Figure 3.6 on page 29).

CAUTION Risk of measuring cell pollution! Before commissioning, the 3/2-way ball valve must be set to PURGE and AU-TOMATIC (see 3.8.5 3/2-way ball valve page 39)!

Figure 5.1: Mounting position optical sensor

1. After removing the housing cover (GRP cover) first insert the optical sensor (D−R 800 F) with its measuring lance into the measurement chamber. There is no need to open the device for that purpose. The adjustment is done as shown in Figure 5.1 (arrow), with angle plug towards middle of the device. Tighten optical sensor with the self-locking nuts to the flange.

2. Check wiring at control unit and sampling probe. 3. Connect external series fuse. 4. Check value and direction of rotation of voltage (400 V) at control unit input. 5. Connect main fuse F01. 6. Connect fuses F02 to F04 and the two protective motorswitches S01 and

S02 one after another.

7. The valve on the blower for the injector air (blue lever in Figure 5.2) is closed during dispatch. Now it has to be opened for operating, but only approx. 80%.

Commissioning

54 D−R 820 F

It is advisable, to remove the blue lever after commissioning and keep it readily available nearby, fastened for example with a cable connector. For this reason it is prevented that the valve position (80%) is modified unchecked.

Figure 5.3: Mounting position valve for allocation of diluting air

8. Inside the probe the valve for allocation of diluting air (Figure 5.3) has to be opened. This valve is also closed during dispatch. It is secured by a two-piece pipe clamp. It is sufficient to untighten only the left side of the pipe clamp. After this, the valve can be opened with some turns. Finally the pipe clamp protection is tightened on the opened valve.

9. Wait until the diluting air has reached a value of min. 1 m³/h.The value is shown in the display behind identifier FD.

10. Connect the diluting air heat element with fuse F05 11. Connect the probe ventilation with fuse F06

CAUTION Condensate formation! Risk of measuring cell pollution! Cancellation of the preheating is not recommended!

12. The device is in the mode Preheating = ON (see 6.9.11 Set probe heat

element | page 72). The preheating time ends after 30 minutes. 13. After expiry of the preheating time, the device switches to measuring mode. 14. After switching from purge (preheating) to measurement, the device re-

mains in maintenance status for 1 minute. 15. The measured values, shown in the display of the control unit (Value T and

TD is displayed alternately), should be consistent with the values specified in Table 5.1. If the displayed value FD (volume flow) is not yet in the range of ap-prox. 3 ... 6 m³/h, the valve of the blower injector air has to be opened or closed respectively (see point 7 above).

6.1 Optical sensor The optical sensor is described in detail in a separate manual (D-R 800). Ho-wever, this information is generally irrelevant for use as a measuring probe in the D−R 820 F, as all necessary settings are performed and monitored by the D−R 820 F system. Therefore the user does not need to perform any settings on the sensor. The D−R 820 F is operated with the factory setting.

Do not change any settings on the optical sensor! Otherwise, control by the D−R 820 F and functioning of the complete system will no longer be guaran-teed. Checking or changing the settings of the D−R 800 F is only necessary and ex-pedient in exceptional cases. Checks or changes should therefore only be car-ried out after consulting the Service department. You will find the relevant ad-dresses and telephone numbers on page 121 (DURAG GROUP company ad-dresses)

Calibration

D−R 820 F 79

8 Calibration

8.1 Device calibration

8.1.1 Device calibration; General As a highly sensitive measuring device, the D−R 820 F is subject to the fine fluctuations of the components and materials used. For this reason the refer-ence point of the optical sensor is compared, in order to detect any errors in the sensor in good time. The zero point of the optical sensor does not have to be calibrated. The actual reference point is defined during the device calibration.

This calibration exclusively relates to the electronics of the D−R 820 F and not the gravimetric calibration (generally by test institute). This is at the customer's discretion.

8.1.2 Performing calibration The device is calibrated in accordance with the instructions under point 6.8 page 65. The calibration takes approx. 3 minutes. When calibration is com-plete, the D−R 820 F returns to the Calibration menu. The new reference value can be checked with the key.

The 3/2-way ball valve should be set to purge for device calibration!

The displayed reference value should be between 60 and 80%!

8.2 Dust calibration

8.2.1 Dust calibration; General The measured value acquisition is subject to a wide variety of influences, due to the different technological conditions at the relevant measuring points. Vari-able influence factors include type of dust, gas speed and temperature. The dusts to be measured vary, for example, in particle size, density, particle sha-pe, charge and other dust and gas characteristics. Consequently, a different characteristic curve results for the output signal in relation to the dust content for each case of operation of a D−R 820 F. The signals of the D−R 820 F must therefore be calibrated with gravimetric comparison measurements (in accor-dance with VDI 2066 and VDI 3950 in Germany). The results of the calibration, i.e. the parameters, can be entered directly in the D−R 820 F, and the device outputs a signal proportional to the dust content.

8.2.3 Performing calibration

Before starting the calibration, you must ensure that the device (point 6.9.2 page 66) and operating parameters (point 6.9.3 page 67) are correctly en-tered. You must also ensure that the error "MB sensor too small*" does not occur during calibration (status line, or erorr log)!!

If the optical sensor outputs the error "MB sensor too small" (MB Hardware MessBereich/Measuring Range) during the gravimetric comparison measure-ment, then this measurement cannot be used for the dust calibration and must therefore be repeated! (see error log) This applies similarly for every error that puts the D−R 820 F into fault condition. In addition, it should be noted that the D−R 820 F performs the zero and refer-ence point test automatically, and no data are available for the comparison measurement during this time.

10 Error messages and error elimination

The D−R 820 F outputs status signals for monitoring, indicating error states and troubleshooting. These are made available on the display in plain text and at the status contacts (see connection diagram) as a potential-free contact. The error messages are divided into the classes maintenance, maintenance requirement and fault. All current events are shown one after another in the status line of the display. The last 100 errors and events are stored in the error log of the D−R 820 F. You can also see the dependency of the events here, based on time and se-quence. After exiting the Calibration or Parameter menu with the <set> key (see Figure 6.4: SET switch on page 64), all events are deleted, i.e. the status display is reconfigured and any new events are written to the error log.

If the messages/causes of the maintenance requirement category cannot be eliminated, please inform the competent Service department! (DURAG GROUP company addresses see page 121)

10.1 Events Provided that no maintenance, maintenance requirement or fault is present, all

displayed events are only informative in nature.

After calling the parameter setting or calibration with the <set> key, any main-tenance requirement or fault message present is reset.

10.2 Maintenance status "Maintenance status" is shown in the display. Maintenance operating status occurs at the following times: • Service mode or parameter input active • 4-hour zero and reference point control active (see point 3.8.4 Zero and

reference point page 38) • Device is in purge position (see chapter 3.8.5 3/2-way ball valve page 39) • Manual maintenance switch is on (see Figure 3.8: Control unit, page 31) • The device is switched to maintenance status via a remote control (serial

communication) (the device keyboard is locked during remote mainte-nance!)

• The optical sensor is in maintenance status

After switching from purge to measurement, the D−R 820 F remains in pur-ge/maintenance status for another minute!

When the maintenance switch (see Figure 3.8: Control unit, page 31) is in the maintenance position, the ball valve is not automatically set to purge if FX is less than 80%FXmin and in the event of a sensor error !

10.3 Maintenance requirement status "Maintenance requirement" is shown in the display.


10.4 Fault status "Fault status" is shown in the display.

If the ball valve is moved into the "Measurement" position via the control key) when a fault is present, all events are deleted and the status display/error evaluation is reconfigured.

Claus plant All H2S--containing exhaust gases that de-velop are processed in the Claus plant. The toxic H2S is converted into elementary sul-phur and water during this process.

Cyclical communication Interface communica-tion in which data are bundled into data packets and transferred in a defined order, separated by defined characters (e.g. semi-colon).

Dilution Thinning or dilution is a measure for the concentration of the extracted measuring gas. The dilution is specified in [%].

Extinction <lat.>: (Phys.) Attenuation of a wave motion (radiation) when passing through a medium After conversion of the transmission into absorbance and after a (→) gravimetric comparison measurement, the display oc-curs in mg/m³. For dust concentrations this result is specified in mg/Nm³ through com-putation to the reference values T, P, RF.

extractive Extractive measuring procedures are cha-racterised by the fact that the sample to be analysed is withdrawn from the meas-uring gas line, conditioned and fed to the analysis device via a sample line and sample processing.

Forward scattering In physics scattering generally refers to the deflection of an object through inter-action with another local object (scattering centre). An example is the scattering of light on fine particulates. Forward scatter-ing refers to scattering processes in which only a small deflection occurs (small scat-tering angle). The measurement is there-fore recorded from the front, so against the beam direction.

Frame This generally means a data packet in this manual

Gravimetry <lat.>: (Chem.) Measurement analysis;

method for quantitative definition of ele-ments and groups in mixtures of materials.

In-situ situ measuring method The term in situ (lat. for at the (original) lo-cation, on the premises, "on the spot") in environmental technology denotes the exe-cution of defined procedures on the spot.

Modbus (interface communication) The Modbus protocol is a communication protocol based on a master/slave or cli-ent/server architecture. Modbus has be-come a facto standard in industry, as it is an open protocol. A master (e.g. a PC) and several slaves (e.g. measurement and control systems) can be connected by means of Modbus.

Offset or adjustment offset In this manual offset denotes a static va-lue which is added to or subtracted from a measured value, in order to adjust the ze-ro value, for example.

Opacity <lat>: (Optics) Nontransparency A light beam sent through a mixture of gas and particles is attenuated by absorp-tion and diffusion. The more particles are found in the light beam, the stronger the opacity. The ratio of received light to initial light is a measurement of the transmis-sion or the reciprocal opacity.

Reciprocal <lat.>: mutual; Reciprocal value: (Math.) Inverse value (swapping numerators and nominators of a fraction)

RS485 interface - analogous to the RS422 interface - has been developed for serial high-speed da-ta transfer over long distances and is be-coming increasingly widespread in the in-dustrial sector. The data cables must be implemented as twisted pairs.

Scattered light A light source emits light which is diffused by particles in the gas and recorded by a detector. The scattered light principle is suitable for small dust loads to under 1 mg/m³. The relationship between meas-ured value display and dust load is de-termined by means of (→) gravimetric comparison measurement.
