12 300 Series Level Transmitter/ Controller

The 12300 type Digital Level Transmitter/controller is ahigh performance, easy-to-set instrument based on amodular design that permits quick, low-cost upgrades asnew features are developed and as your needs change.

1.1 Principle of Operation

The Masoneilan 12300 series instrument is a 2-wire, looppowered, digital displacement level transmitter/controllerwith HART ® Communication that uses field provenbuoyancy and torque tube principles.

A change in liquid level varies the apparent weight of thedisplacer (130), which increases or decreases load on thetorque tube (136) by an amount directly proportional to thechange in liquid level.

The resulting rotation of the torque rod (138) modifies themagnetic field of a frictionless, non-contacting, Hall effect

sensor (141). The signal generated by the sensor variescurrent in the loop in proportion to the level in the vessel.

1.2 Signal Processing

The analog signal is converted into an error-free digitalsignal that can be processed by the on-board micro-controller. After the signal has been processed, the digitalresult is converted to a 4-20 mA analog output signal *.

- If the 12300 is configurated as transmitter, this 4-20mA analog output signal is the level measure.

- If the 12300 is configurated as controller, this 4-20 mAanalog output signal is not the level measure but theposition setpoint sent to the valve, so that the valvecontrols to achieve the required level setpoint. The12300 electronic turns then the signal of the Hall effectsensor into a different type of signal ( : valve position

Installation in a hazardous atmosphere must be performedin accordance with the requirements specified in the appli-cable standard for protection against explosion.

a) Transmitters Designed to be Installed in anIntrinsically Safe Circuit, according to EuropeanStandards EN 50014 and EN 50020 (CENELEC):

EEx ia IIC T6 (– 40 °C ≤ Ambient temperature ≤ 50 °C)

EEx ia IIC T5 (– 40 °C ≤ Ambient temperature ≤ 60 °C)

EEx ia IIC T4 (– 40 °C ≤ Ambient temperature ≤ 80 °C)

The main feature of this protection system is that nospark nor any thermal effect produced under the testsconditions required by the standard is capable ofcausing ignition of a given explosive atmosphere.

WARNING : Improper replacement or substitution ofelectronic components or of certain parts whosecharacteristics do not meet requirements of theapplicable standards for explosion protection mayvoid this protection.

Important:

- The controller option of the 12300 is available only ifthe customer has ordered a 12300 controller (seefig.2 - numbering system) he will then be able to confi-gure the 12300 wether as transmitter or as controller.

- If the customer has ordered a 12300 transmitter (seefig.2 - numbering system) he will then only be able toconfigure the 12300 as transmitter.

- The relevant controller information are discribed inannex F and in the HDLT communicator (joined).

The instrument is powered through the 2-wire series loop.

The instrument can be retrofitted to old style electronic orpneumatic heads to upgrade an instrument already inservice.

The complete circuit is defined in the approval documentissued by a recognized certification agency :

3.2 MOUNTING ON SITE

Unpack the unit carefully and record the serial number forfuture reference. Remove the shipping stud that securesthe displacer in the chamber.

Whenever possible, locate the transmitter at some easilyaccessible, well-lighted place on the vessel. The locationshould be such that the ambient temperature at the trans-mitter case is within the range of – 40 °C to +80 °C.

Note : Do not remove instrument cover until the unit hasbeen installed and is ready for calibration.

The codes shown on Figure 2 indicate the instrument desi-gnation as a function of various installation modes, displa-cer chamber connections, and environmental standard orprotection of the case against explosion. Figures 3 and 6show the various ways of installing the displacer chamber.

3.2.1 EXTERNAL MOUNTING(Chamber Type Model, Figures 3 and 6)

Install the transmitter in a vertical position on the side of thetank or vessel, so that the mid-range mark on the chamberis at normal level. The mid-range is marked on the cham-ber.

The equalizing lines between chamber and vessel shouldbe the same size as the chamber connections. Install ablock valve in each line. The use of a drain connection isrecommended as shown in Figure 3.

The displacer is always immobilized in the displacer cham-ber to avoid any internal damage during transportation.

During the level mounting, the displacer has to be unlockedby unscrewing the M6 stern at the drain.

3.2.2 INTERNAL MOUNTING

An internally mounted transmitter has no displacer cham-ber and the mechanism chamber bolts directly to the vesselnozzle flange.

a) Type 12303 Top Flange Mounted Transmitter(Figure 4)

There are two mounting possibilities :

1. If the overhead space necessary for mounting theinstrument is sufficient, attach the displacer to thetorque tube before bolting the chamber flange to thenozzle flange on the vessel.

2. If the overhead space is insufficient, install a deta-chable hanger extension. Before attaching the exten-sion, however, lower the displacer partway into thetank.

• After the extension has been fastened and pinned tothe displacer, the displacer may be hooked to thetorque arm and the entire unit lowered into position.When the extension consists of several detachableelements, this operation should be repeated for eachelement and the displacer lowered progressively intothe tank.

• Mount the instrument and bolt the mechanism cham-ber onto the nozzle flange.

7Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

Figure 2 – Numbering System

b) Type 12304 Side Flange Mounted Transmitter(Figure 5)

When the instrument is side flange mounted, enough clea-rance must be provided to permit attachment of the displa-cer after the chamber flange is bolted in place. To attachthe displacer, reach into the end of the protective case anddepress the torque arm. Then bring the displacer hangerup through the hole in the bottom of the case and slip thedisplacer hanger over the torque arm pin. Lower the displa-cer until the pin engages the top of the slot in the hanger.

Guide Brackets for Type 12304 (Figure 5)

If the liquid is in motion, provide brackets as shown inFigure 5 to guide the lower end of the displacer. Thediameter of the hole should be 25 to 35 mm (1” to 1 1/2”)larger than the diameter of the displacer for ranges to 1.8 m(6 feet), and 50 to 70 mm (2” to 3”) larger for greaterranges. The brackets should be placed at 50 to 70 mm (2”to 3”) from each end of the displacer. Locate the centerlineof the hole so that the displacer hangs freely.

Stilling Well for Type 12303 (Figure 4)

If the liquid is turbulent, provide a stilling well as shown inFigure 4.

The well should be made from tubing or pipe of a suitablediameter to allow sufficient clearance between displacerand pipe. It should be mounted so that it extends at least75 mm (3”) below a free hanging displacer.

A hole at the top of the stilling well should be provided toequalize pressure between well and vessel.

Instrument Case Mounting (Figure 7)

The standard case mounting is left hand — the case is tothe left of the displacer. Right hand mounting is optional. Toreverse instrument case mounting, refer to Section 6 —Maintenance.

9Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

The purpose of this section is to describe the various sub-assemblies of the instrument in order to facilitate their useand maintenance. (See Figures 19 to 21).

4.1 ELECTRONIC COMPARTMENT

The electronics compartment, located at the front of thetransmitter, can be accessed by removing the maincover (20). This cover contains a window (22) andthree push buttons (27).

The cover (20) is fully screwed on to the case (2), sealedwith an O-ring (109). It may be necessary to unscrew thecover by less than a turn to align the window and LCDdisplay and to install the safety screw (110).

The front plate (80), which is attached by three screws(125), protects the push buttons and provides a gasketseal (24).

The sensor (40) and its seal (111) are secured by twoscrews (112), located in the upper part of theelectronics compartment. The sensor is positioned sothat the blue mark is oriented toward the lower part ofthe case (see Figure 10). Another blue mark on thecase is a visual aid for the operator during reassembly.

The microprocessor, the display and the three pushbuttons are mounted on the potted electronic boardwhich makes the amplifier. This subassembly isinserted into the case with the display facing the top ofthe case. It is assembled by four screws (201).

For wiring, refer to Section 4.4.

4.2 MECHANISM COMPARTMENT

The mechanism compartment (Figures 20 & 21) on theback of the case has an opening on the right side(operator facing instrument) which is closed by athreaded cover (107) and a gasket (108). A secondopening at the bottom, closed by a special 3/4” NPT plug(190), allows access to the mechanical flexure (59),which is part of the beam.

The mechanism (50) [including parts (51 to 62)] iscompletely factory assembled and calibrated beforebeing installed into the mechanism compartment. Thepivot (51) is positioned toward the back of the casethrough two pins (52-53) and fastened by two screws(113). The beam (54) must be free to rotate withoutfriction (up to 7 degrees max.).

Two set screws (114) are located in tapped holes in theside of the case. The holes are covered by two plugs

(115). These set screws have no effect when mountingor dismounting the mechanism subassembly.

4.3 CONNECTION COMPARTMENT

The connection compartment is equipped with aterminal board (90). The flat handle terminal block,the test switch/pins, the HART ® connection pins andthe terminal board connector are mounted on theterminal board. The terminal board is mounted with 2screws (92).

The case is also equipped with radio frequency filterconnections between the terminal board connector andthe main electronic circuit.

4.4.2 SUPPLY - OUTPUT SIGNAL

The standard transmitter provides a 4-20 mA outputsignal to remotely located receivers such as recorders,indicators or controllers.

The supply voltage is :

• Flameproof version, 9,5 to 50 volts max.

• Intrinsic safety version, 9,5 to 30 volts max.

4.4.3 LOAD RESISTANCE

The maximum load resistance in terms of the supplyvoltage may be determined from the curves in Figure 9.The “R” values in brackets correspond to a high alarmof 23 mA.

If more accuracy is required, the maximum load resis-tance (R) may be calculated as follows :

For a supply voltage V (V min. = 9,5 Volts) :

R (Ohms) = V (Volts) — 9,5I max. (Ampere)

In which :

I = Max loop current (information currentof the l iquid level : 3,8 to 20,5 mA ;alarm current : 3,6 to 23 mA).

4.4.4 ELECTRIC CONNECTION

Both the terminal strip and the ground terminal arelocated in an external junction box. A conduit connec-tion (1/2” NPT or M 20) is provided in the lower part ofthe junction box for connecting the supply leads via asupplied stuffing box with an integrated cable clampdevice or any cable gland with cable clamp devicesuitable for the considered hazardous area.

Connect the receiver (load) in series with either one ofthe power supply leads as shown in Figure 8.

Observe the polarities engraved on the terminal strip.

5.1 General PrinciplesAll electronic calibrations of the DLT are made by means ofthree push buttons and a liquid crystal display on the frontof the instrument. The codes or values displayed by theLCD can be seen through a window. Access to the threepush buttons is obtained by removing the protective logoplate (80). It is not necessary to open the main cover forcalibration or adjustment of the instrument. Except formaintenance, the cover should remain closed.

5.1.1 The Liquid Crystal DisplayIt displays two lines and a bargraph. The upper linecan displays to five numerical digits and a decimal dot.The lower line can display alphanumeric digits.

On Normal operation, the LCD sequentially displaysthe loop current in mA and the level expressed in theunit displayed in the low left corner of the screen ; thelevel unit is generally % but an engineering unit canbe selected through [UNIT] in CALIBRATION menu.The bargraph length is proportional to the loopcurrent. The level value always increases with theheight of liquid in the tank or displacer chamberwhatever is the instrument action. For direct action,the current signal increases when level heightincreases ; for reverse action, the current decreaseswhen level increases.

The display is also used to Configure, Calibrate andDiagnose the DLT.

To facilitate these operations, values, codes or shortnames appear on the display. The various parametersare listed in the menus (see APPENDIX A, B, C, D, F).

5.1.2 Pushbuttons

Three pushbuttons (27) are located under the plate(80) on the front of the instrument. Remove the threescrews (125).

The left button is marked with a star , the middlebutton with the sign –, and the right one with the sign+.

means enter the function, accept or save to memory ;may be replaced by YES.

+ or – means : vertical movement in the programstructure ; may be replaced by NO or NEXT orPREVIOUS.

Note : 1. Do not overpush on the buttons. A buttonshould be depressed at least one second toperform the action.

2. Accidental pushing of the buttons will notcause any malfunction.

After using the buttons, reinstall the front plate (80) forNORMAL mode, which alternately displays the currentloop and the level of liquid.

5.1.3 Operating Modes

The instrument can operate under 3 modes :

• NORMAL Mode : it is the normal operating mode.The 4-20 mA output current is proportional to thelevel in the tank. The local digital display alternatelydisplays loop current and level expressed in theunit (% or engineering unit) shown in the low leftcorner of the screen. Reading of the instrumentdatabase is possible.

• MANUAL Mode : enter the manual mode wheninstrument configuration, calibration or diagnostic(set up or reading of diagnostic parameters) isrequired. The output current is not proportional tothe tank level in this mode.

• FAILSAFE Mode : the instrument automatically setsto the failsafe mode when an error or an alarm hasoccurred. The output current is set to the valueentered in the CONFIGURATION Menu.

5.2 Init ial Calibration of anInstrument on Level ServiceTo perform a first calibration and running in case of a levelapplication of the instrument refer to APPENDIX E.

5.3 Calibration Procedures forSpecif ic Parameters andApplications

After the 12300 Level Instrument has been installedand connected, remove the front plate (80) located infront of the instrument to gain access to the pushbuttons and select all required configuration data asindicated in the Section 5.1.4.4. APPENDIX B, thenproceed as follows:

NOTE : The electronic circuit has been factoryadjusted during instrument manufacturing to 4-20 mA,using a reference milliammeter.

So, for calibration on site, no measurement instrumentis required.

However, if the loop current must be verified and if fullcompliance with standards requirements forinstruments installed in hazardous areas is required,insert the milliammeter in series with the power supplyor connect it to the electronic board provided into theconnection compartment. Put the switch on the“TEST” position. Connect the milliammeter on the twopins located on each side of the switch. Beforedisconnecting the milliammeter put the switch back onthe position identified by “”. See Figure 19.

5.3.1 Direct Reading on the LiquidSpecific Gravity Meter [SGMETER]

• If displacer volume is lower than 1270 cm3 andservice specific gravity X displacer volume islower than 1270.

• If the displacer is fully immersed in the liquidand if the [SGMETER] function has beenpreliminary calibrated.

To calibrate the [SGMETER] function, refer toSection 5.3.2.1.

To read specific gravity of the process liquid :

• Fill the displacer chamber until the displacer is fullyimmersed in the process liquid.

• Move into the DIAGNOSTIC Menu (APPENDIX D)until [RD CTR] then [SGMETER] are displayed. Push to read the value. Return to normal operation.

Danger : If area cannot be verified as safe, donot remove any covers.

Caution : Direct reading of specific gravity iscorrect only :

5.3.2 To Set up Parameters

5.3.2.1 Calibrate the Specific Gravity MeterThis adjustment is made at the factory for completeinstruments. Use of the specific gravity function[SGMETER] aids in performing on site newcalibrations of simulations with or without liquid.

Caution : The Specific Gravity Meter function isfactory calibrated at a specific gravity of 1 forcomplete instrument only if the displacervolume is lower than 1270 cm 3 and the weight is1362 g.For an instrument delivered alone with a torquetube, the Specific Gravity Meter function isfactory calibrated at a SG 1 for a displacer with907 cm3 / 1362 g.If actual displacer characteristics differs fromthese values, recalibration is necessary and willbe possible only if displacer volume is lower than1270 cm3 and service specific gravity x displacervolume is lower than 1270 :

Proceed as follows :

a. Move to CALIBRATION Menu (APPENDIX C)until [SGM CAL], then [SG CAL] are displayed.Validate by to enter SETVAL menu and set thespecific gravity of 1. Store data.

b. Empty the chamber or simulate the low level byusing weights and stabilize the displacer (or theweights).

c. Display [ZERO ] and press to set the REF L.

NOTE : During the procedure, refer to Section5.3.2.6 if the LCD displays [ERROR].

d. Attach a set of weights to the torque arm tosimulate a high level or fill the displacer chamberuntil the high level is reached. Stabilize thedisplacer (or the weight).

• On site : Fill the displacer chamber until highlevel (REF H) is reached by a specific gravity1 liquid.

• In workshop : Simulate by weights the highlevel (REF H) corresponding to the apparentweight of the actual displacer fully immersedin a specific gravity 1 liquid.

e. Display [SPAN ] and press to set the REF H,

f. Move until [<– ] is displayed and press tostore data via [STORAGE] and [YES NO]screens. [CAL Z S] is displayed,

g. Exit the CALIBRATION Menu via [<–MANU] and then move into the DIAGNOSTIC menu(APPENDIX D) until [RD CTR] then [SGMETER]are displayed. Push to read the value andcheck if the calibration is successful. Return toNORMAL Operation Mode.

5.3.2.2 Calibration Specific Gravity [SG CAL]The calibration specific gravity is that of the liquid used(or simulated by weights) for calibration of zero andspan in the CALIBRATION Menu.

It should be modified only if zero and span calibrationare performed again for a liquid of different specificgravity. Refer to Section 5.3.3.4—Calibration, Steps 1to 7.

5.3.2.3 Service Specific Gravity [SG SER]

The service specific gravity is the one used for thefunction [SG SER] in the CALIBRATION Menu.

Its value is identical to that of [SG CAL] just aftercalibration. If the specific gravity of the processliquid is different, modify the value of [SG SER].

Two cases are possible :

a) If the specific gravity of the liquid is unknown ,you must first measure specific gravity of the liquidby using the function [SGMETER]. See Section5.3.1, then proceed as follows :

b) If the specific gravity is known, it can bemodified, regardless of what the liquid level in thedisplacer chamber is. To adjust the value :

Move into the CALIBRATION Menu until [CALIBR],[CHG SG] then [SG SER] are displayed.

Validate by to enter SETVAL menu and set thespecific gravity. Return to normal operation.

5.3.2.4 Output Current Damping [DAMPING]

In case of rapid oscillations of the level or if theliquid is in motion, it may be necessary to filter theoutput signal. A first order digital filter is provided foradjusting the damping coefficient.

Enter the CALIBRATION Menu, move to display[VAR SET], then [DAMPING] and validate by toenter SETVAL menu and set the filtering coefficient.Return to normal operation.

5.3.2.5 Reduced Range and /or Zero Shift[SPAN > – <], [ZERO <–>]

For an application where the level change is smallerthan the displacer height, it is possible to obtain thefull signal range for this reduced level range.

• Enter the CALIBRATION Menu, move to display[VAR SET], then [ZERO <–>] and validate by toenter SETVAL menu and set the zero shift value.Return to the [ZERO <–>] screen by ,

• Move to display [SPAN > – <] and validate by toenter SETVAL menu and set the span reductionvalue. Return to display [SPAN > – <] screen by ,

• Move until [<– ] is displayed and press to storedata via [STORAGE] and [YES NO] screens.[VAR SET] is displayed,

Caution : In interface service , if the [LSG SER]and/or [HSG SER] are modified, an automaticcalculation is performed to set a new value in[ZERO <–>].

17Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

• Exit the CALIBRATION Menu via [<–MANU] and then return to NORMAL Operation Mode via theMANUAL Mode.

Example : To modify a calibration so that 0 %corresponds to a displacer immersed to 1/4 of itsheight (25 %), and 100 % corresponds to a displa-cer immersed to 4/5 of its height (80 %), adjustzero shift to 25 % and span reduction to 45 %,(see schematic on Figure 11).

5.3.2.6 Error Code on Zero and Span Set

a) The value of the span can be accepted before orafter the zero value is entered. If you accept thezero without simulating the corresponding levelchange, the LCD displays [ERROR]. Press todelete the message and then perform (or simu-late) the level change before acquiring the newvalue.

b) The LCD may also display [ERROR] for a newcalibration if :

• The zero value is higher or equal to the span ofthe preceding calibration. If so, accept andstore the span first and then the zero.

• The span value of the new calibration is smal-ler than the zero value of the preceding calibra-tion. If so, accept and store the zero value firstand then the span.

5.3.3 Calibration (for Level InstrumentService)

5.3.3.1 Principle of CalibrationThe electronic circuit is calibrated towards tworeference levels (REF L and REF H), see Schematicbelow :

• REF L corresponds to the displacer completely out ofliquid.

• REF H corresponds to the displacer fully immersedin the liquid of Specific Gravity used for calibration[SG CAL].

The loop current corresponding to REF L may be setthrough [MA L] via [VAR SET] ; it is generally 4 mA.

The current corresponding to REF H may be setthrough [MA H] via [VAR SET] ; it is generally 20 mA.

Caution : If new calibration is performed, theparameters of the reduced range [SPAN > – <]and/or zero shift function [ZERO <–>] areautomatically set to zero.In interface service : If the [LSG SER] and/or[HSG SER] are modified, an automatic calcula-tion is performed to set a new value in[ZERO <–>].

Figure 11Schematic Example of Reduced Range

18Instruction No EU 3500 E 04/2000

12 300 Series Level Transmitter/ Controller

The value of [MA H] shall always be higher than thevalue of [MA L].

The level indication corresponding to REF L is setthrough function [LEVEL L] via [VAR SET] ; it isexpressed in the unit set through [UNIT] function ; ifUNIT is “%”, LEVEL L should be 0.0.

The level indication corresponding to REF H is setthrough function [LEVEL H] via [VAR SET] ; it isexpressed in the unit set through [UNIT] function ; ifUNIT is “%”, LEVEL H should be 100.0.

The electronic circuit is calibrated so that the indicatorrange 4-20 mA corresponds to the indication of amilliammeter inserted in series with the supply circuitof the DLT. Therefore it is not necessary to connect amilliammeter when performing an on site calibration ;the instrument display is sufficient.

5.3.3.2 Conditions for Dry Calibration inWorkshop (Simulation by Weights)

Parameter Name S.I Units English UnitsDisplacer Weight g lbmDisplacer Volume cm3 in3

Water Density (WD) 1 g/cm3 0.036 lbm/in3

The effective change in level will be simulated by aset of weights corresponding to :

a) The weight of the actual displacer at low level(REF L), which allows you to calibrate the zeroand obtain the minimum value [ 0,0%] of thesignal (direct action).

b) The apparent displacer weight when the levelis high (REF H). This allows you to calibrate thespan and obtain the maximum value [100,0%] ofthe signal (direct action). The correspondingweight is calculated as :

Proceed as indicated under 5.3.3.4 Calibration :

5.3.3.3 Conditions for Calibration in the fieldwith a Liquid

The effective change in level will be obtained byemptying and filling of the displacer chamber with aliquid.

Wait for the displacer to stabilize to validate thevalues displayed after each change in liquid level.

Take actions necessary to allow a change in theliquid level in the chamber : open/close isolationvalves, vent, purge, etc.

Proceed as indicated under 5.3.3.4 Calibration :

Apparent Displacer Weight =Displacer Actual Weight – (Displacer Actual Volume x S.G.x WD)

Danger : Connection of a milliammeter in seriesmust be compatible with applicable hazardousarea standards requirements. Refer to Section4.4.4.

Caution : When performing a calibration, use thefollowing parameter units wherever they apply :

Caution : Actual volume and weight of the displa-cer can be read using HART ® protocol only ifthey have been previously stored in the DLT head.Otherwise, actual volume of the displacer ismarked on the specification plate (124).

Weigh the displacer to get the actual weight.

19Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

NOTE : The calibration specific gravity [SGCAL] is automatically stored in the service speci-fic gravity function [SG SER]. If the instrument isto be used with a liquid of different specificgravity, reenter the CALIBRATION Menu to setand accept this new value in [SG SER]. (SeeSection 5.3.2.3).

5.3.4 Calibration of an Instrument forLiquid Interface Service5.3.4.1 Principle of CalibrationThe level transmitter is used to measure the interfacelevel of two immiscible liquids of different specificgravit ies. The displacer must always be fullyimmersed.

The electronic circuit is calibrated towards tworeference levels (REF L and REF H) :

• REF L corresponds to the displacer completely out ofliquid.

• REF H corresponds to the displacer fully immersedin the liquid of Specific Gravity used for calibration[SG CAL].

The loop current corresponding to REF L may be setthrough [MA L] via [VAR SET] ; it is generally 4 mA.

The current corresponding to REF H may be setthrough [MA H] via [VAR SET] ; it is generally 20 mA.

The value of [MA H] shall always be higher than thevalue of [MA L].

The level indication corresponding to REF L is setthrough function [LEVEL L] via [VAR SET] ; it isexpressed in the unit set through [UNIT] function ; ifUNIT is “%”, LEVEL L should be 0.0.

The level indication corresponding to REF H is setthrough function [LEVEL H] via [VAR SET] ; it isexpressed in the unit set through [UNIT] function ; ifUNIT is “%”, LEVEL H should be 100.0.

The electronic circuit is calibrated so that the indicatorrange 4-20 mA corresponds to the indication of amilliammeter inserted in series with the supply circuitof the DLT.

Therefore it is not necessary to connect amilliammeter when performing an on site calibration ;the instrument display is sufficient.

5.3.4.2. General Information on interfaceservice displacers

Under this Section we will consider a standarddisplacer any displacer with the followingcharacteristics :

• Volume V : ≤ 1270 cm3 (≤ 77 in3), marked onspecification plate (124),

• Product of V x SG ≤ 1270,• Weight = 1362 g (3 lbm).

A standard displacer may be used when the liquidspecific gravity difference is between 0.1 and 1.4 (withlower accuracy between 0.1 to 0.2). The lowest specificgravity (d1) liquid is 1.3 max. The highest specific gravity(d2) liquid is between 0.1 and 1.4.

Danger : Connection of a milliammeter in seriesmust be compatible with applicable hazardous areastandards and requirements. Refer to Section 4.4.4.

Caution : Special displacers may be provided forspecific applications (material, service condi-tions…). In these cases, volume and/or weight willdiffer from standard displacer characteris tics.

Actual volume and weight of the displacer canbe read using HART ® protocol only if they havebeen previously stored in the DLT head.Otherwise, actual volume of the displacer ismarked on the specification plate (124).

NOTE : During following procedures, refer to Section5.3.2.6 if the LCD displays [ERROR].

5.3.4.2.1 Wet Calibration

The effective change in level will be obtained byemptying and filling of the displacer chamberwith the two liquids .

Wait for the displacer to stabilize to validate thevalues displayed after each change in interfaceof liquids.

Take actions necessary to allow a change in theinterface of liquids in the chamber : open/closeisolation valves, vent, purge, etc.

The procedure is identical to the one used forcalibrating a level transmitter in a liquid on site(see Section 5.3.3.4), except for the differencesoutlined below.

a. With the Process Liquids

1. Enter the specific gravities to be used for cali-bration by using the functions [LSG CAL]and [HSG CAL].

2. Take necessary action to allow change in liquidinterface level in the displacer chamber suchas isolating, vent, purge valves etc....It is thennecessary to put liquids in the chamber to:

3. Set the [ZERO]when the displacer is fully immer-sed in the lowest specific gravity liquid (d1).

4. Set the [SPAN] when the displacer is fully immer-sed in the highest specific gravity liquid (d2).

5. Complete the calibration as indicated inSteps 7 to 15 of the Section 5.3.3.4.

b. With the Highest Specific Gravity Liquid (d 2)

1. Take necessary action to allow change inliquid interface level in the displacer chambersuch as isolating, vent, purge valves etc....and then :

2. Enter the CALIBRATION Menu.

3. Enter the specific gravities to be used for cali-bration by using the functions [LSG CAL]and [HSG CAL].

4. Admit liquid (d2) into the chamber to fullyimmerse the displacer.

5. Set and store [SPAN] for interface configura-tion.

6. Quit CALIBRATION Menu.

7. In the DIAGNOSTIC Menu, move to [SGME-TER]. The specific gravity displayed mustcorrespond to the specific gravity of the liquidin the chamber. This assumes the [SGME-TER] has been calibrated.

8. Slowly empty the chamber until the LCDdisplays the lowest S.G. value (d1) andrecord this value.

9. Quit the [SGMETER] function and theDIAGNOSTIC Menu.

10. Return to CALIBRATION Menu.

11. Set the [ZERO] for interface configuration.

12. Complete the calibration as indicated inSteps 7 to 15 of the Section 5.3.3.4.

c. On Site Using Water if the Highest SpecificGravity (d 2) is ≤ 1

1. Take necessary action to allow change inliquid interface level in the displacer chambersuch as isolating, vent, purge valves etc....and then empty the chamber.

2. Enter the DIAGNOSTIC Menu and move to[SGMETER].

3. Increase the water level in the displacerchamber until LCD displays the value of theprocess lowest specific gravity (d1).

4. Quit [SGMETER] and enter the CALIBRA-TION Menu. Move until [CAL Z S], then [LSGCAL] and [HSG CAL] is displayed to enter(d1) and (d2).

5. Set and store [ZERO] for this water level (d1).

6. Quit the CALIBRATION Menu and return to[SGMETER] in the DIAGNOSTIC Menu.

7. Increase the water level in the displacerchamber until the LCD displays the value ofthe highest specific gravity (d2).

8. Quit [SGMETER] and the DIAGNOSTICMenu, then return to CALIBRATION Menu.

9. Set and store the [SPAN] for this new waterlevel (d2).

10. Complete the calibration as indicated inSteps 7 to 15 of the Section 5.3.3.4.

Weight of the displacer is only necessary on drycalibration to simulate the apparent weight ofthe displacer immersed into the liquids : Weighthe displacer to get the actual weight.

Caution : This procedure is only possible ifthe [SGMETER] function has been calibra-ted. Refer to Section 5.3.1.

5.3.4.2.2. Dry Calibration

Conditions for Dry Calibration in a Workshop(Simulation by Weights)

Caution : When performing a calibration, use thefollowing parameter units wherever they apply :

Parameter Name S.I Units English UnitsDisplacer Weight g lbmDisplacer Volume cm3 in3

Water Density (WD) 1 g/cm3 0.036 lbm/in3

Caution : Actual volume and weight of thedisplacer can be read using HART ® functiononly if they have been previously stored inthe DLT head. Otherwise, actual volume of thedisplacer is marked on the specification plate(124).Weight of the displacer is only necessary ondry calibration to simulate the apparentweight of the displacer immersed in theliquids : Weigh the displacer to get the actualweight.

a. In the Workshop (Simulation by Weights)

The procedure is identical to the one used for anormal level transmitter service (see Section5.3.3.4), except the set of weights is calculatedas follows :

• To simulate an interface at 0 % (REF L) and cali-brate the zero, attach to the torque arm a weightequal to the actual displacer weight when fullyimmersed in the lowest specific gravity liquid,which is calculated as :

• To simulate an interface at 100 % (REF H) andcalibrate the span, attach to the torque arm aweight equal to the effective displacer weightwhen fully immersed in the highest specificgravity liquid, which is calculated as :

Enter in [LSG CAL] and [HSG CAL] the processliquids specific gravities (d1) and (d2).

b. With or Without Liquid in the DisplacerChamber (Use of Adjusting Screws tocalibrate)

Caution : This procedure is only possible ifthe [SGMETER] function has been calibrated.Refer to Section 5.3.1.

This method uses the [SGMETER] function (setin workshop), to adjust the screws (114) to theinterface specific gravities.

If a milliammeter is not required, this calibrationmay be performed with the case closed.

Open the access plug (107) on the right side ofthe case to look at the simulation mechanism.Remove plug (190) and the two 1/8 ” NPT plugs(115). (Use a 5 mm Hex. wrench).

Through this hole, use your finger to move theflexure (59) in the direction of the torque tube untilthe flexure touches the adjusting screw post(114). While maintaining contact, slide the flexureleft or right along the surface of the screw post,(Figure 12).

Adjusting the Screws (114)

Adjust the screw (114) on the displacer side, rela-tive to the instrument axis, to simulate the forceon the displacer resulting from the highest speci-fic gravity of the process liquids (d2).

Adjust the screw (114) on the opposite side to thedisplacer to simulate the force on the displacerresulting from the lowest specific gravity of theprocess liquids (d1).

Displacer Apparent Weight for REF H =Displ. Actual Weight – (Displ. Actual Volume x d2 x WD)

Displacer Apparent Weight for REF L =Displ. Actual Weight – (Displ. Actual Volume x d1 x WD)

Caution : During the dry calibration withoutmechanism chamber, DO NOT ATTACH ASPECIAL INTERFACE SERVICE DISPLA-CER (OR ITS EQUIVALENT EFFECTIVEWEIGHT) on the torque arm. These displa-cers are heavier than those for liquid levelservice. Any mechanical stop is possibleout of mechanism chamber, causing inevi-table damage to the torque tube and/or theDLT mechanism.

3. Press the flexure (59) against the adjustingscrew shoulder (114) which corresponds tothe highest specific gravity, d2. While maintai-ning contact and using a 3 mm hex wrench,turn the adjusting screw until LCD displaysd2.

4. Slowly move from one shoulder to the other(to avoid displacer oscillations) and verify thevalue displayed. Correct adjustments ifnecessary.

5. Quit the [SGMETER] function and return to[MANUAL] display.

Calibration with screws (114)

1. Enter the CALIBRATION Menu and move todisplay [CHG SG], then [LSG SER] and[HSG SER]. Read these two values andreturn to [CHG SG].

2. Move to [CAL Z S] then to [LSG CAL] and[HSG CAL] to enter the specific gravities (d1)and (d2).

3. Move to display [ZERO]. Press the flexure(59) to contact the lowest specific gravityadjusting screw (114) (opposite to the displa-cer side). Wait for a few seconds until thedisplacer stabilizes and accept the zerovalue.

4. Move to display [SPAN]. Move the flexure(59) to contact the shoulder of the screw(114) corresponding to the highest specificgravity (on displacer side). Wait a fewseconds until displacer is stable and acceptthe span value.

5. Release the flexure.

6. Complete the calibration as indicated in Steps7 to 15 of the Section 5.3.3.4.

7. Reinstall plugs (107), (190), and (115).

NOTE : If the displacer chamber is empty, theLCD will display an incorrect negative value.

The zero of the LCD is correct only when thedisplacer is fully immersed in the lowestspecific gravity liquid.

Moving the flexure from one shoulder to theother varies the display and the loop currentfrom 0 to 100 %.

f. Position the case correctly oriented toward the frontand in line with the axis of the torque tube.

g. Slide the case into the torque tube flange whileobserving through the side opening that the pin(72) is inserted into the beam coupling end. Use aflat tool to easy backup the coupling flexure (71).

h. When the case is in contact with the torque tubeflange, verify that the beam is free to rotate byplacing your finger on the flexure (59) through thelower 3/4 ” NPT hole.

i. Fasten the case with four screws (121) andwashers (122). Firmly tighten.

j. Verify again that the beam is free to rotate and thatthe coupling flexure (71) is not deformed. Thecoupling on the beam (54) will be tightened later.

NOTE : At this point, if instrument service condi-tions are well defined, refer to Section 6.2.3 —Instrument Coupling to the Torque Tube inWorkshop or Section 6.2.4 — Instrument Couplingto the Torque Tube on Site

6.2.2 12120/12800 Series Torque Tube(See Figure 14)

The transmitter can be mounted on different types ofexisting torque tubes. Kits including flange, gasket,and screws are provided for the adapter tubes.

6.2.3 Workshop Calibration of Coupling

Coupling between torque tube and mechanism isachieved by simulating a 1.4 specific gravity liquid. Thevalue of the weights is determined by the formulabelow, (see section d).

NOTE : It is necessary to know the mounting direction(right or left) and the action direction of the signal(direct or reverse) — refer to Section 5.1.4.4 – CONFI-GURATION Menu and APPENDIX B.

a. Using a support, install the transmitter and itstorque tube.

b. Remove the screw (106 ), the covers (104 & 107) ofthe connection and mechanism compartments, andthe plug (190) located at the bottom of the instru-ment.

c. Assemble the standard torque arm on the right orleft side as required. (Refer to Figure 7).

d. Attach to the torque arm a weight equivalent to thatof a displacer half immersed in a 1.4 specificgravity liquid :

Calibr. Weight = Displacer Actual Weight –(Displacer Actual Volume x WD x 1.4)2

e. Connect a 24 V dc supply (switch OFF) to the termi-nals in the connection compartment in series with amilliammeter. Note polarities.

6.2.4 Coupling to the Torque Tube on Site(in the Process Liquid)

The DLT case can be mounted on an installed torquetube. In this case, procedures described in Section6.2.3 should be performed on site.

In coupling the torque tube to the mechanismsubassembly (which starts at step 6.2.3. d), twosituations may occur :

• If the specific gravity (or the difference of theSG in case of an interface service) of the avai-lable liquid is between 0.7 and 1.4 : simulate halflevel h (1.4) of a 1.4 specific gravity liquid with acalculated value h (d) of the available liquid (refer tochart Figure 16).

• If the specific gravity (d3) (or the difference of theSG in case of an interface service) of the avai-lable liquid is below 0.7, perform the coupling at ahigh level.

a. If necessary, assemble the right adapter kit andverify that the torque tube is satisfactory — SeeSections 6.2.1 or 6.2.2.

b. Install the instrument — see Section 6.2.1 or 6.2.2.

c. Make electrical connections — See Section 4.4.

d. Proceed with configuration of the instrument. Referto Section 5.1.4.4 – CONFIGURATION menu.

e. Set the coupling between torque tube and mechanismsubassembly—See Section 6.2.3, Steps g to m.

f. Calibrate the instrument — See Section 5.3.3 or5.3.4.

6.2.5 Setting Adjusting Screws for SG 1 inLevel Service (Figures 12 & 19 to 21)

Two screws (114) are located in holes on the side ofthe case, closed by two plugs 1/8 ” NPT (115). Theyare positioned at factory assembly using the stepfollowing specific gravity meter calibration, (refer toSection 5.3.2.1). They can be adjusted at the time ofcalibration.

Caution : In this situation, the instrument mustbe used for specific gravities (or the differenceof SG) ranging from 0.2 to 2 d3.

26Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

These adjusting screws allow the user on site :

• For level interface service : To calibrate theinstrument, with or without liquid, (see Section5.3.4.2.2, b.).

• For liquid level service : To simulate, withoutliquid, a change in level of a specific gravity 1liquid.

In this last case, proceed as follows :

To adjust stops, put the instrument into the precedingcalibrated specific gravity meter function [SGMETER](Refer to APPENDIX D).

Open the access plug (107) to look at the simulationmechanism. Remove the 3/4” NPT plug (190) locatedat the bottom of instrument.

Through the 3/4 ” NPT opening, use your finger tomove the flexure (59) in the direction of the torquetube until it seats on the smooth end of the screws(114). While maintaining pressure, slide the flexure tothe right or the left until it stops against the screwshoulder. See Figure 12.

Relative to the instrument axis, adjust the screw ondisplacer side to simulate a high level of S.G. 1 liquid(REF H). Use the screw on the side opposite to thedisplacer to simulate a low level (REF L) (displacerchamber empty).

In practice, proceed as follows :

a. Simulate low level (REF L) :

In the workshop, attach to the displacer arm aweight equal to actual displacer.

On site, the displacer chamber should be empty.

b. Remove plugs (115) using a 5 mm hex wrench.

c. Using the push buttons, enter the DIAGNOSTICMenu and move to the specific gravity meter func-tion [SGMETER]. Validate by . The LCD display avalue around [ 0.000].

6.4 Install ing a Torque Tube withassembled DLT Case (Figure 18)

The case mounting direction for which the couplinghas been made may be identified as follows :

When the case is mounted and coupled to the torquetube (without torque arm or displacer), the tip of theconical pin (53) is aligned with one side of the ovalhole in the flexure (59) :

• Left mounting : see Figure 18 a.• Right mounting : see Figure 18 b.

For installation, reverse the procedure outlined forremoving a DLT case and torque tube subassembly(Section 6.3). It is recommended that new gaskets(143 - 149) be used when installation is performed,(refer to Figure 17).

NOTE : If the coupling does not match the mountingdirection, verify that the screw (62) is loose and pin(72) is free to rotate in the coupling end of the beam(54) before hooking the displacer on the torque arm(135).

Continue by performing operations g to i in Section6.5, unless the instrument is already prepared and

calibrated for the specific application required by thecustomer. In such a case, however, it is recommendedthat you check the adjustments of the specific gravitymeter function, adjusting screws, and the calibration,before returning the instrument to normal service.

CALIBRATION (Appendix C)

Conditions to Dry Calibration inWorkshop (Simulation by Weights)

Caution : When performing a calibration, usethe following parameter units wherever theyapply :

Parameter Name S.I Units English UnitsDisplacer Weight g lbmDisplacer Volume cm3 in3

Water Density (WD) 1 g/cm3 0.036 lbm/in3

The effective change in level will be simulatedby a set of weights corresponding to :

a) The weight of the actual displacer at lowlevel (REF L), which allows you to calibratethe zero and obtain the minimum value [0,0%] of the signal (direct action).

b) The apparent displacer weight when thelevel is high (REF H). This allows you tocalibrate the span and obtain the maximumvalue [100,0%] of the signal (direct action).The corresponding weight is calculated as :

Caution : Special displacer may be providedfor specific applications (material, serviceconditions…). In this case, volume and/orweight will differ from standard displacercharacteristics.

Actual volume and weight of the displacercan be read using HART function only ifthey have been previously stored in the DLThead. Otherwise, actual volume of thedisplacer is marked on the specificationplate (124).Weight the displacer to get the actualweight.

Apparent Displacer Weight =Displacer Actual Weight – (Displacer Actual Volume x S.G.x WD)

Danger : If area cannot be verified as safe, do notremove any covers.

APPENDIX E FIRST OPERATING AND SIMPLE CALIBRATION FOR A LEVEL INSTRUMENT SERVICE

Instruction No EU 3500 E 04/200012 300 Series Level Transmitter/ Controller

APPENDIX FSPECIFIC MODES

This annex describes two specific operating modes.1 Push button locking.

In MANUAL MODE, the use of push button can belocked by sending a specific HART message with the275 communicator (loaded with the relevant DDL).

This locking prevents any change in the menusCONFIGURATION, CALIBRATION and DIAGNOSTIC.

However, the MANUAL MODE can be unlocked when

using the password stored in the HDLT during the 275communicator locking operation. Th MANUAL MODEis automatically locked again when the user go back toNORMAL MODE. The MANUAL MODE unlockingthrough the push buttons is then temporary. Thesketch below indicates how unlocking the MANUALMODE with the pasword:

2 Controller mode.

When the CONTROLLER MODE is enabled in theCONFIGURATION menu:[CTRL I]; the NORMALMODE menu is displayed differently. Three data are

displayed alternatively: the liquid level, the loop currentand the controller set point. The following sketchindicates how to modify the controller setpoint:

Remarks :

- The controller set point can be modified even if thepush buttons are locked.

- The loop current doesn't indicate the liquid level butthe controller output (which is the valve position setpoint).

- The controller set point is always displayed by theLCD in level unit.

- If the set point and level units are different, the ratiocontrol is activated and you have to calculate andenter the good values of the Ratio gain and Ratiobias (see the 275 communicator instruction EU 3500HC E). A bad set point display is then avoided.

Local SP unit Engineering units for the controller setpoint. A choice of many units is proposed . This unit is alsoused by Initial local SP, Low SP value, High SP value, SP low limit, SP high limit.

Ratio control Ratio control is ON : -if controller setpoint unit and level units are different . -if same unit but scale for setpoint and scale for level are not the same.Ratio control is automatically set in case of different units but not for different scale.If ratio control is ON, the two parameters RATIO GAIN and RATIO BIAS must be set using theformula : SP in process variable units = Ratio gain * SP in its units + Ratio bias

Initial local SP At power up , in case of micro-controller re-start or if HDLT RESET has been performed , this setpointwill be use by the controller.

Low SP value Controller setpoint low value corresponding to low level of liquid (Low level).

High SP value Controller setpoint high value corresponding to low level of liquid (High level).

SP low limit Minimum value for the setpoint allowed.

SP high limit Maximum value for the setpoint allowed.

Alarm Alarm type could be absolute or deviation. This alarm is done on the level of liquid.ABSOLUTE= alarm detection is done on the real level of liquid.DEVIATION=alarm detection is done on the error between the level of liquid and the controller setpointexpressed in the level engineering unit .

Low alarm limit Controller low alarm. Alarms can be absolute or deviation. This value is expressed in level engineeringunit. In case of deviation alarm, the Low alarm limit must be a negative number .

High Alarm Limit Controller high alarm. Alarms can be absolute or deviation. This value is expressed in level engineeringunit. In case of deviation alarm, the High alarm limit musy be a positive number .

Controller action DIRECT or REVERSE action.DIRECT action means the controller output increases if the error=level-setpoint is a positive number.REVERSE action means the controller output increases if the error= setpoint - level is a positivenumber.

Derivative source The derivative action can be done on the process variable (the level of liquid) or on the error.

Controller rate Controller rate to process the PID algorithm. The value must be between 0.2s and 10.0s.For some very slow process, the rate can be ajusted to avoid instability ,fast controller output change ora satured controller output. In other cases the low value is better to ajust the PID parameters.The general rule is to set the controller rate 10 times greater than the frequency cut of the process.

Output Rate Limit Limits the controller output changes. This value is expressed in % output / second.The maximum value is 500%/s .

Dead zone The controller don't change its current output if the difference between the setpoint and the processvariable (level) is less than the Dead zone. The range is 0.0% to 20.0%.

Manual Reset Bias It is the controller output at a typical operating steady state.Use in P or PD process algorithm .Can be used in PID algorithm if the setpoint change are small and in stable process.Must be set to zero if not used.

Ratio Gain Use if the process variable (level) and the setpoint are expressed in different engineering units or indifferent scales. This variable is used with RATIO BIAS in the following formula: SP in process variable units = Ratio gain * SP in its units + Ratio biasRemarks : the formula is made if RATIO CONTROL is ON.

Ration Bias Use if the process variable (level) and the setpoint are expressed in different engineering units or indifferent scales.

2 PID setting Sub-menu to set tuning PID coefficients.

P Proportionnal gain. It is the ratio of proportionnal controller output to error. Value between 0 and 50.

I Integral time or reset time expressed in second. Value between 0 and 1000 seconds.

D Derivative time or rate time. Value between 0 and 5000 milliseconds.

Kd Derivative gain to control the derivative action. Value between 0 and 100.

Beta Coefficient to change the proportionnal gain . The range is -9 to +9 . When Beta is 0 no action is doneon P.When Beta =+9 , P is multiplied by 2 is error is greater than 20% and decrease to P value for error=0.When Beta =-9 , P is divised by 2 is error is greater than 20% and increase to P value for error=0.

3 setpoint To change the local controller setpoint.
