Introduction III

INTRODUCTION

The DT301 (Touché) Intelligent Concentration/Density Transmitter is an instrument designed for the continuous onlinemeasurement of liquid concentration/density, directly in the industrial process.

The DT301 consists of a capacitive type differential pressure transmitter coupled to a pair of pressure repeaters immersedin the process. The repeaters are connected to the external capacitive sensor through capillary tubes. A temperature sensorlocated between the two pressure repeaters automatically compensates temperature variations in the process

Special techniques in the production and assembly repeaters and temperature sensor, ensure that small variations in theprocess temperature are quickly informed to the transmitter, that calculates the fluid density process accurately through adedicated software.

Depending on the industrial process, density can be expressed in Density, Relative Density, Brix degree, Baumé degree,Plato degree, % of Solids, Concentration, etc.

Designed for process control applications, this 2-wire transmitter generates a 4-20 mA signal proportional to theconcentration/density. Digital communication for remote calibration and monitoring is also provided (Protocol Hart).

The digital technology used in the DT301 allows the choice of several types of transfer functions, an easy interface betweenthe field and the control room and some characteristics that reduce the installation, operation and the maintenance costsconsiderably.

ATTENTION

Get the best results of the DT301 by carefully reading these instructions.

Instalation 1.1

1 – INSTALLATION

GENERAL

The overall accuracy of density measurement dependson several variables. Although the transmitter has anoutstanding performance, proper installation is essentialto maximize its performance.

Among all factors, which may affect transmitter accuracy,environmental conditions are the most difficult to control.There are, however, ways of reducing the effects oftemperature, humidity and vibration.

The capacitive sensor of the DT301, that is locatedexternal to the process, is protected of external sourcesof heat by an enclosure with internal thermal insulation.Nevertheless, the transmitter should be installed in way toavoid to the maximum the direct exhibition to the ray’srun.

Humidity is fatal to electronic circuits. In areas subjectedto high relative humidity, the O-rings for the electronichousing covers must be correctly placed and the coversmust be completely closed by tighten them by hand untilyou feel the O-rings being compressed. Do not use toolsto close the covers. Removal of the electronics cover inthe field should be reduced to the minimum necessary,since each time it is removed; the circuits are exposed tothe humidity. The electronic circuit is protected by ahumidity proof coating, but frequent exposures tohumidity may affect the protection provided. It is alsoimportant to keep the covers tightened in place. Everytime they are removed, the threads are exposed tocorrosion, since painting cannot protect these parts.Code-approved sealing methods should be employed onconduit entering the transmitter. The unused outletconnection should be plugged accordingly.

Although the transmitter is virtually insensitive to vibration,installation close to pumps, turbines or other vibratingequipment should be avoided.

Proper winterization (freeze protection) should beemployed to prevent freezing, since this can result in aninoperative transmitter and could even damage the cell.

RECOMMENDATIONS FOR USE OF THE DT301

The process fluid should always cover the two diaphragmrepeaters. (See the Fig. 1.2).

The maximum speed of the process fluid under thediaphragms repeaters must be 0,4 m/s, which in a pipewith diameter of 6 '' it corresponds to a flow of 26 m³/h.These data applies to fluids with close viscosity of thewater. Fluids with very different viscosity should beanalyzed.

This limitation is due to the pressure drop between thediaphragms.The temperature of the process fluid must be within 0°Cand 120°C.

For applications in corrosive fluids, compatible materialsshould be chosen. The materials of the parts that are notin direct contact with the process, but can be subject tothe corrosive atmosphere or drops of the process, shouldalso be observed.

A possible leak of the fill fluid (less than 5 ml), due to ahole in the diaphragm can contaminate the process. Incase that is not allowed, choose a fill fluid compatible withthe process.

Verify if the fill fluid doesn't evaporate in the extremeconditions of temperature and pressure of the process.

TRANSMITTERS MODELS OF CONCENTRATION /DENSITY DT301

DT301I - Industrial model, for general purpose

DT301S - Sanitary model for food, pharmaceuticalindustry and other applications where sanitaryconnections are required.

The industrial model uses connection flanges accordingto ANSI B16.5 or DIN 2526 standards.

The sanitary model uses Tri-Clamp connection to allow aquick and easy connection and disconnection from theprocess. Wetted surface finish is 32Ra as standard.These model meet 3A recommendations so that theprobe surface is free of crevices where food or bacteriacan be collected. 3A is the most widely accepted sanitarystandard in the food, drug and beverage industry.

ASSEMBLY

Both models have two mounting types: top mounting(straight type) and side mounting (curved type).

The Figure 1.1 shows the dimensions of the DT301straight and curved type for industrial and sanitarymodels.

The installation can be done in open or pressurized tanksor through a sampling device, external to the process.

The Figure1.2 shows some mounting examples.

Choose a place for installation that facilitates the accessfor the measuring point and that be free from mechanicalshocks.

Instalation 1.3

Fig. 1.2 – Mounting types for the DT301


Try to use a valve in the connection to the process beforethe DT301, this simplifies the calibration and maintenanceof the equipment.

ELECTRONIC HOUSING ROTATIONThe electronic housing can be rotated in order to betterposition the digital display. To rotate it, use the HousingRotation Set Screw, see Figure 1.3

WARNING: EXPLOSION PROOF INSTALLATIONS

The electronic housing and the sensor assembly in potentiallyexplosive atmospheres must have a minimum of 6 threadsfully engaged. The provided joint allows 1 turn extra. Try toadjust the display window position by rotating the housingclockwise. If the thread reaches the end before the desiredposition, then rotate the housing counterclockwise, but not bymore than one turn of the thread end. Transmitters have astopper that restricts housing rotation to one turn. See Section4, Figure 4.1.

The digital display can also be rotated. See Section 4,Figure 4.2.

ELECTRIC WIRINGReach the wiring block by removing the ElectricalConnection Cover. The cover locking screw (Figure 1.3)locks this cover. To release the cover, rotate the lockingscrew clockwise.

Fig. 1.3 – Housing Rotation Set Screw

The wiring block has screws on which fork or ring typeterminals can be fastened. See Figure 1.4.

HAZARDOUS AREAS

In hazardous zones with explosion proof requirements the coversmust be tightened with at least 7 turns. In order to avoid moistureor corrosive gases, hand tight the covers until the O-rings arecompressed. Lock the covers closed with the locking screw.

Observed in hazardous zones with intrinsically safe or non-incendive requirements, the circuit entity parameters andapplicable installation procedures.

Obtain cable access to wiring connections by one of the twoconduit outlets. Should seal conduit threads by means of code-approved sealing methods. Plug and seal the unused outletconnection accordingly. Explosion proof, non-incendive andintrinsic safety Factory Mutual certification are standards forDT301.

Should other certifications be necessary, refer to the certificationor specific standard for installation limitations.

Fig. 1.4 – Wiring Block

For convenience, there are two ground terminals: oneinside the cover and one external located close to theconduit entries.

Use of twisted pair (22 AWG or greater than) cables isrecommended.

Avoid routing signal wiring close to power cables orswitching equipment. Plug and seal the unused outletconnection accordingly.

The DT301 has protection against reverse polarity.Connection of the DT301 should be done as inFigure1.6.

ATTENTION:

For proper operation, the Hand-Held Terminal requiresa minimum load of 250 Ohm between it and the powersupply.

Fig. 1.5 – Load Curve

Instalation 1.5

Fig. 1.6 – DT301 Connection Diagram.

MULTIDROP OPERATIONMultidrop connection is formed by several transmitterconnected to a single communication transmission line.Communication between the host and the transmitterstakes place digitally with the transmitters analog outputdeactivated.

The communication with the transmitters and the host(HT2, DCS, Data Acquisition System or PC) can be donewith a Bell 202 Modem using Hart Protocol. Eachtransmitter is identified by a unique address from 1 to 15.Contact Smar Service to specify the requirements formultidrop applications.

Special consideration should be given to the update ratein multidrop configuration communication.

Not however that the updating of the analog output, incontroller mode, is not affected.

The DT301 is factory set to address 0, that means a nonmultidrop operation mode, allowing the transmitter tocommunicative with the Hand-Held Terminal,superimposing the communication on the 4-20 mAsignal. To operate in multidrop mode, the transmitteraddress must be changed to a number from 1 to 15. Thischange deactivates the 4-20 mA analog output sendingit to 4mA.

NOTE:

The current output will be fastened in 4 mA as soon as thetransmitter address it is changed of zero (0) for another onein the multidrop range (1 to 15).

When intrinsic safety is a requirement, special attentionmust be paid to the entity parameters allowed to thatarea:

Operation 2.1

2 – OPERATION

FUNCTIONAL DESCRIPTION – SENSORThe pressure sensor used by the DT301 SmartConcentration/ Density Transmitter is a capacitive cell, thesame type used by the LD301 Smart PressureTransmitter. This sensor is connected to a probe toaccomplish the measures through of the pressuredifferential reading. The Figure 2.1 schematizes thesensor used by the DT301.

Fig. 2.1 – Capacitive Cell

Where,

P1 and P2 are the pressures applied in cameras H and L.

CH = capacitance between the fixed plate on P1 sideand the sensing diaphragm.

CL = capacitance between the fixed plate on the P2

side and the sensing diaphragm.

d = distance between CH and CL fixed plates.

∆∆d = sensing diaphragm's deflection due to thedifferential pressure ∆P = P1 - P2.

Knowing that the capacitance of a capacitor with flat,parallel plates may be expressed as a function of platearea (A) and distance (d) between the plates:

Where,

εε = dielectric constant of the medium between thecapacitor's plates.

Should CH and CL be considered the capacity of flat andparallel plates with identical areas, then:

However, should the differential pressure (∆P) applied tothe capacitive cell not deflect the sensing diaphragmbeyond d/4, it is possible to assume ∆P as proportionalto ∆d, that is:

∆P α ∆d

By developing the expression (CL - CH)/(CL + CH), itfollows that:

As the distance (d) between the fixed plates CH and CLis constant. It is possible to conclude that the expression(CL - CH)/(CL + CH) is proportional to ∆d and, therefore,to the differential pressure to be measured.

Thus it is possible to conclude that the capacitive cell is apressure sensor formed by two capacitors whosecapacitances vary according to the differential pressureapplied.

FUNCTIONAL DESCRIPTION - HARDWAREThe transmitter blocks Diagram, as it shows the Figure2.2, it describes the circuit used by the DT301functionally.

Programming Using Hand-Held Terminal 3.1

3 – PROGRAMMING USING HAND-HELD TERMINAL

THE HAND-HELD TERMINAL

\SMAR Hand-Held Terminal (HT2) is the man-machine interfaceused to maximize the advances of digital technology. Theterminal's front face is shown on Figure 3.1.

Fig 3.1 - SMAR Hand-Held Terminal

SMAR Hand-Held Terminal (HT2) Software has the followingfeatures:

§ Transmitter identification and specification data.

§ Remote reranging without using a reference pressure source.

§ Constant current adjustment from 3.9 to 21 mA for loop test.

§ Monitoring of all transmitter variables: PV, PV%, output, error,and process temperature.

§ Diagnosis and determining faults in the processor or thetransmitter.

The operations, which take place between the HT2 and thetransmitter do not interrupt the Pressure measurement, and donot disturb the output signal. The HT2 can be connected on thesame pair of wires as the 4-20 mA signal, up to 2 km away fromthe transmitter. It is necessary to introduce an impedance ( eitherinductive or reactive ) between the power supply and thetransmitters, so that the communication signal may besuperimposed to the power supply level.

The standard model shall not be used in Hazardous Areas.

Fitting the BatteryThe HT2 uses any 9 Volt PP3 size battery, however for longeroperating life, use of alkaline batteries is recommended. Removethe protective case by pulling it firmly downwards. Pull the tab toremove the battery cover and observe polarity. The programmerstandard model cannot be utilized in hazardous areas.

Fitting the Datapack and RampackThe datapack is the module where the DT301 configurationsoftware for the HT2 is stored. Make sure it is marked DT301,and put it into slot B. Another Rampack/Datapack can be usedfor storage of off-line configurations into slot C, although data canbe also stored in the HT2 RAM. After loading the configurationsoftware on the programmer, the software will remain resident onits RAM memory until the programmer is de-energized.

The following programming packs are available for the user:

ü Data Pack – this pack is built based on PROM or EPROMmemories;

ü RAM Pack – this pack is built based on RAM memories;ü Flash Pack – this pack is built based on Flash memories.

ATTENTION:

Should RAM packs be used, do not energize the programmer while thePACK is connected to it!

The RAM Pack could be formatted and the data would be deleted.

MEASUREMENTThis configuration menu function of the SMAR HT 2 Programmermakes it possible to select the type of transference function thetransmitter is expected to perform. There are several functionsrelated with the measurement of density and concentration, andthere is a special function which makes it possible to check the 4to 20 mA current generated by the transmitter. The followingtransference functions have been implemented:

DensityThe transference functions related to the measurement of densitycorrespond to the measurement of absolute densitymeasurement, which takes into consideration the chemicalproperties of the solution and the physical properties of themedium, and to the measurement of specific gravity, which isbased on the density of water. Therefore, it is possible to performmeasurements in the following units: kg/m3, g/cm3, SGU@ 20º C,SGU@ 4ºC.

ConcentrationSuch measurements inform the composition of a solution incomparison with several worldwide accepted units, such as:Baumé Degrees, Plato Degrees, Brix Degrees and INPMDegrees.

Constant OutputThis measurement allows the user to check the consistency ofthe input current generation values between 3.9 and 21 mA. Thisis also an extremely important characteristic while performing theLoop Testing during the Startup of an Industrial plant.

/CONF TAG XMTR[ Constant Output ]Enter_Const._CurrentExit_Const._Current

Example: Upon entering < EXE > while the cursor is on theMeasurement option of the configuration menu, informationrelated with the measurement selection will be displayed.Entering < Y >, the measurement options shown on Figure 3.4may be selected.

CONSTANTSAll measurements performed by the transmitter, with theexception of the fixed current, are calculated in accordance withthe physical and chemical properties of the solution and

the medium, respectively. However, due to intrinsic characteristicsof this transmitter, the only information required for the transmitterto perform correct measurements is the gravity acceleration,expressed in m/s2. Such information is provided in this option ofthe configuration menu.

ATENTION:

Alter this variable only if the local gravity acceleration figure is known.The use of an incorrect figure will cause measurement errors in thespan, which will require a new calibration. In order to correct amistakenly entered information, since return to the normal accelerationfigure, 9.80665, if no adjustments have been made.

Example: How to alter the default value of the gravity accelerationfrom 9.80665 m/s2 to 9.8 m/s2 : by entering < EXE > with thecursor placed on option Constants and then on the variable gl – local gravity, both display types will be presented. Upon entering < Y > to confirm the alteration, the programmer will enter theediting mode, thus allowing a new value to be entered inreplacement for the previous value. By using key < EXE > it ispossible to confirm the alteration that has been performed. It isnot necessary to enter the figures together with key < SHIFT >,since the programmer is prepared to recognize only numerickeys.

FAIL SAFEThis configuration option includes the possibility of choosing theoutput current action, should a failure occur. The output currentwill remain fixed within the limits of Lower Burnout or UpperBurnout, depending on the failure mode chosen.

The user does not choose the upper and lower burnout currentlimits. These limits are previously determined in accordance withthe transmitter version. The lower current limit is 3.9 mA and thelatest versions comply with the specifications of standard NAMURNE-43, that is , 3.6 mA. In what respects to the upper limit, allversions use the same limit: 21 mA. The selection of DownBurnout and Upper Burnout is done by means of mode switchingdevice, by pushing key < EXE > on option BURNOUT.

TRIM FINE ADJUST - TRIMThe TRIM function is used to make the transmitter readingcomply with the user's pressure and current standards.These two types of readouts, Current and Pressure, may beadjusted either in fine tuning, in order to correct minor hardware

deviations or, as in the particular case of Pressure, to determinethe working range selected by the User.

CURRENT TRIM (4-20 mA)When the microprocessor generates a 0% signal, the Digital toAnalog converter and associated electronics are supposed todeliver a 4 mA output. If the signal is 100%, the output should be20 mA.

There might be differences between the factory current standardsand your plant current standard. In this case, you may use thecurrent TRIM adjustment as follows:

§ Connect the transmitter to your plant precision milliammeterwith a 0.03 % precision readout.

§ Select the TRIM function. The display will show:

/TRIM TAG XMTR

Select the desired point, e.g., 4 mA and press the <EXE> key.The display will show:

/TRIM TAG XMTR[4mA Current Trim]Enter Line Currenti(mA) = _

/TRIM TAG XMTR[ Trim de i (4mA) ]

Valor de Corrente

If the reading is 4.00 mA, answer Yes <Y>. If the reading is, forexample, 4.012 mA, press <N> (No).

/TRIM TAG XMTR[ Trim de i (4mA) ]Entrar valor de i:i(mA)= _

Type 4.01 and press <EXE>.

The display will repeat the question if the current is correct or not.Answer it properly till the reading is 4.00 mA. Enter the sameprocedure shall be applied for the 20 mA.

PRESSURE TRIMEach sensor has a characteristic curve that establishes a relationbetween the applied pressure and the sensor signal. This curveis determined for each sensor and it is stored in a memory of thesensor circuit. When the sensor is connected to the transmittercircuit, the contents of its memory is made


available to the microprocessor, that relate the sensor’s signal tothe measure pressure.

Sometimes the transmitter display and/or the HT2 display readingmay differ from the applied pressure.

The reason may be:

§ The transmitter mounting position.§ The user's pressure standard differs from the factory standard.§ The transmitter had its original characterization shifted by

overpressure, overtemperature or by long term drift.

The pressure TRIM is used to match the reading with the appliedpressure.

There are two types of pressure trim available:

1. LOWER TRIM: Is used to trim the reading at the lower range.The user informs the transmitter the correct reading for theapplied pressure via the HT2.

2. UPPER TRIM: Is used to trim the reading at the upper range.The user informs the transmitter the correct reading for theapplied pressure via the HT2.

By selecting TRIM and PRESSURE , the display will show:Press the following cursor keys: < ↓ > and < ↑ > to select the trimoptions.

Move the cursor to the desired option and press key < EXE >

/TRIM TAG XMTRLower_PressureUpper_PressureExit

ATTENTION:

This is a factory adjustment, so the user must not perform it on the field.Should it be necessary to perform this adjustment on the field, apressure standard with an accuracy equal to or better than 0.015% ofthe pressure to be applied must be used

The upper pressure trim shall be adjusted only after the adjustment ofthe lower pressure trim..

LOWER PRESSURE TRIMThe most common discrepancy is the lower reading. The shift inZERO may be compensated by the LOWER PRESSURE TRIM.To have a digital reading more accurate it is recommended tocalibrate LOWER PRESSURE TRIM with the same valuecalibrated in the LOWER RANGE VALUE.

After consequently selecting TRIM, and LOWER PRESSURE,the display will show:

/TRIM TAG XMTR[Lower Press. Trim ]P(mmH2O20)= 510Is it correct ? Y/N

Should the readout be sufficiently close to the pressure applied,press key < Y > (yes); otherwise, press key < N > (no).Supposing that, in this example, the applied pressure is 50mmH2O, you shall press key < N > in order to make thecorrection.

The display will show:

/TRIM TAG XMTR[Lower Press. Trim ]Enter pressure valueP(mmH2020) = _

Enter the correct value; type 500 followed by <EXE>. The displaywill show:

/TRIM TAG XMTR[Lower Press. Trim ]P(mmH2O20) = 500Is it correct ? Y/N

Since it is now corrected, press <Y> to confirm. The whole curvewas shifted to cancel the offset.

UPPER PRESSURE TRIMUnder some particular operating conditions, the sensormechanical gain may be slightly modified. This reflects on thepressure reading. In order to adjust the reading to the desiredvalue, apply the UPPER RANGE VALUE of the desiredcalibration range and select the UPPER PRESSURE TRIM. Inorder to have a more accurate digital reading it is recommendedto calibrate the UPPER PRESSURE TRIM with the same valueas the calibrated UPPER RANGE VALUE.

The Upper Pressure TRIM corrects any distortions occurred onthe mechanical gain of the sensor, by acting on the transferencecurve span. The Upper Pressure Trim adjustment procedure isidentical to that of the Lower Pressure trim, which has beenexplained on the previous paragraph. All steps shall be followedin the same order, simply changing the reference from lower toupper.

MAINTENANCE - MAINTThis function makes it possible to access all information, whichare relevant for the maintenance of the transmitter. Figure 3.5shows all options offered by this function.

4 - MAINTENANCE PROCEDURES

GENERAL

SMAR DT301 intelligent pressure transmitters are extensivelytested and inspected before delivery to the end user.Nevertheless, during their design and development, considerationwas given to the possibility of repairs by the end user, ifnecessary.

As main characteristics how much to the maintenance easinessit can be detached its modularity and its reduced number ofelectronic board.

In general, it is recommended that end users do not try to repairprinted circuit boards. Spare circuit boards may be ordered fromSMAR whenever necessary.

The DT301 concentration/density transmitter has been designedto operate for many years without malfunctions. Should theprocess application require periodic cleaning of the repeaterdiaphragms, the flanges may be easily removed and reinstalled.

Should the transmitter eventually require maintenance, it may bechanged in the field. In this case, the possibly damaged sensorshould be returned to SMAR for evaluation and, if necessary,repair. Refer to the item "Returning Materials" at the end of thisSection.

DIAGNOSTIC WITH HAND-HELD TERMINALShould any problem be noticed relating to the transmitter output,investigation may be carried out bythe HHT, as long as power is supplied and communication andthe processing unit are operating normally (see Table 4.1).

The programmer should be connected to the transmitteraccording to the wiring diagram shown on Section 1, Figures, 1.6and 1.7.

A 21.0 or 3.9 mA current indicates that the transmitter is in safetyoutput or fail-safe output mode. Use the HT2 to investigate the sourceof the problem.

DISASSEMBLY PROCEDURE

WARNING:

Do not disassemble with power on.

Figure 4.3 and 4.4 show transmitter's exploded view and will helpyou to understand the text below.

The numbers between parenthesis are relating to theenumeration of the items of the related drawing.

GROUP OF THE PROBE (16A, 16B, 17A or 17B)

To have access to the probe for cleaning, it is necessary toremove it from the process.

Remove the transmitter loosening the against-flange.

Cleaning should be done carefully in order to avoid damaging ofthe delicate isolating diaphragms. Use of a soft cloth and anonacid solution is recommended.

To remove the sensor from the electronic housing, the electricalconnections (in the field terminal side) and the main boardconnector must be disconnected.

Loosen the hex screw (6) and carefully unscrew the electronichousing from the sensor, observing that the flat cable is notexcessively twisted.

IMPORTANT:

The transmitters have a stopper that can be released to allow thesensor to rotate more than one turn. See Figure 5.1.

CAUTION:

Do not rotate the electronic housing more than 180º withoutdisconnecting the electronic circuit from the sensor and from the powersupply.

Fig. 4.1 – Sensor Rotation Stopper

ELECTRONIC CIRCUITTo remove the circuit board (5), loosen the two screw (3) thatanchor the board.

WARNING:

The board has CMOS components, which may be damaged byelectrostatic discharges. Observe correct procedures for handlingCMOS components. It is also recommended to store the circuit boardsin electrostatic-proof cases.

Pull the main board out of the housing and disconnect the powersupply and the sensor connectors.

REASSEMBLY PROCEDURE

WARNING:

Do not assemble with power on.

GROUP OF THE PROBE (16A, 16B, 17A or 17B)The bolts, nuts, flanges and other parts should be inspected forcorrosion or other eventual damage. Damaged parts should bereplaced.

The fitting of the sensor must be done with the main board out ofthe electronic housing. Mount the sensor to the housing turningclockwise until it stops. Then turn it counterclockwise until it facesthe protective cover (1) parallel to the process flange. Tighten thehex screw (6) to lock the housing to the sensor. Only after thatinstall main board.

ELECTRONIC CIRCUITPlug sensor connector and power supply connector to mainboard.

Attach the display to the main board. Observe the four possiblemounting positions (Figure 4.2). The SMAR mark indicates upposition.


Fig. 4.2 – Four Possible Positions of the Display

Anchor the main board and display with their screw (3).

After tightening the protective cover (1), mounting procedure iscomplete. The transmitter is ready to be energized and tested.

INTERCHANGEABILITY

In order to obtain an, accurate and better temperaturecompensated response, the data of the sensor should betransferred for EEPROM of the main board. That is doneautomatically when the transmitter is energized.

In this operation, then main circuit reads the number of series of

the sensor. If he differs of the number stored in the main board,the circuit will interpreted that there was change of the sensor andit will look for in the new sensor memory its characteristics:- Temperature compensation coefficients.- Sensor's TRIM data, including characterization curve;- Sensor characteristics: type, range, diaphragm material and fill

fluid.

This data must be transferred to the main circuit board.

The other information are stored in the main circuit memory andare not affected by sensor change.

Data transfer from the sensor to the main circuit can also beforced by function MAINT/BACKUP/READ FROM SENSOR.

In the case of change of the main board, the information of thesensor, as described above are up-to-date. Even so, theinformation of the transmitter as upper Value, lower Value,Damping and output unit must be reconfigured.

RETURNING MATERIALS

Should it become necessary to return the transmitter and/orHand-Held Terminal to SMAR, simply contact our office,informing the defective instrument's serial number, and return itto our factory.

In order to speed up analysis and solution of the problem, thedefective item should be returned with a description of the failureobserved, with as much details as possible. Other informationconcerning to the instrument operation, such as service andprocess conditions, is also helpful.
