NoteNo person may install, operate, ormaintain a DLC3000 Series digitalvalve controller without first beingfully trained and qualified in valve,actuator and accessory installation,operation and maintenance, and carefully reading and understandingthe contents of this manual. If youhave any questions regarding theseinstructions, contact your Fisher salesoffice before proceeding.

Product DescriptionType DLC3010 digital level controllers (figure 1-1) areused with level sensors to measure liquid level, thelevel of interface between two liquids, or liquid specificgravity (density). They are communicating,microprocessor-based sensing instruments. In additionto the normal function of providing a 4 to 20milliampere current signal, Type DLC3010 digital levelcontrollers, using the HARTcommunicationsprotocol, give easy access to information critical toprocess operation.

These digital level controllers are designed to directlyreplace standard pneumatic and electronic leveltransmitters, and mount on a wide variety of Fisher249 Series cageless and caged level sensors. TypeDLC3010 digital level controllers mount on othermanufacturers’ displacer type level sensors with rotaryshaft outputs through the use of mounting adaptors.

Use of this GuideThis guide describes how to install, setup, andcalibrate DLC3000 Series digital level controllers.Additional information for installing, operating, andmaintaining the DLC3000 Series digital levelcontrollers can be found in the related documentslisted on page 4-8.

This guide describes instrument setup and calibrationusing a Model 375 Field Communicator. Forinformation on using the Model 375 FieldCommunicator, see the Product Manual for the FieldCommunicator, available from Emerson PerformanceTechnologies. An abbreviated description of FieldCommunicator operation is also contained in theDLC3000 instruction manual.

Procedures that can be accomplished with the use ofthe Model 375 Field Communicator have the Field

Communicator symbol in the heading.

Installation

September 2005 2-1

1-1 22-2This section contains digital level controller installationinformation, including an installation flowchart (figure2-1), mounting and electrical installation information,and a discussion of failure mode jumpers.

Configuration: On the Bench or inthe LoopConfigure the digital level controller before or afterinstallation. It may be useful to configure theinstrument on the bench before installation to ensureproper operation, and to familiarize yourself with itsfunctionality.

Protecting the Coupling andFlexures

CAUTION

Damage to flexures and other parts cancause measurement errors. Observethe following steps before moving thesensor and controller.

Lever LockThe lever lock is built in to the coupling access door.When the door is open, it positions the lever in theneutral travel position for coupling. In some cases, thisfunction is used to protect the lever assembly fromviolent motion during shipment.A DLC3010 controller will have one of the followingmechanical configurations when received:1. A fully assembled and coupled caged-displacersystem is shipped with the displacer or driver rodblocked within the operating range by mechanicalmeans. In this case, the access handle (figure 2-5) will

be in the unlocked position. Remove thedisplacer-blocking hardware before calibration. (Seethe appropriate sensor instruction manual). Thecoupling should be intact.

CAUTION

When shipping an instrument mountedon a sensor, if the lever assembly iscoupled to the linkage, and the linkageis constrained by the displacer blocks,use of the lever lock may result indamage to bellows joints or flexure.

2. If the displacer cannot be blocked because of cageconfiguration or other concerns, the transmitter isuncoupled from the torque tube by loosening thecoupling nut, and the access handle will be in thelocked position. Before placing such a configurationinto service, perform the Coupling procedure.

3. For a cageless system where the displacer is notconnected to the torque tube during shipping, thetorque tube itself stabilizes the coupled lever positionby resting against a physical stop in the sensor. Theaccess handle will be in the unlocked position. Mountthe sensor and hang the displacer. The couplingshould be intact.

4. If the controller was shipped alone, the accesshandle will be in the locked position. All of theMounting, Coupling and Calibration procedures mustbe performed.

The access handle includes a retaining set screw, asshown in figures 2-5 and 2-7. The screw is driven in tocontact the spring plate in the handle assembly beforeshipping. It secures the handle in the desired positionduring shipping and operation. To open or close theaccess door, this set screw must be backed out so thatits top is flush with the handle surface.

WARNING

To avoid personal injury, always wearprotective gloves, clothing, andeyewear when performing anyinstallation operations.Personal injury or property damagedue to sudden release of pressure,contact with hazardous fluid, fire, orexplosion can be caused bypuncturing, heating, or repairing adisplacer that is retaining processpressure or fluid. This danger may notbe readily apparent whendisassembling the sensor or removingthe displacer. Before disassemblingthe sensor or removing the displacer,observe the appropriate warningsprovided in the sensor instructionmanual.Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

Mounting the 249 Series Sensor

The 249 Series sensor is mounted using one of twomethods, depending on the specific type of sensor. Ifthe sensor has a caged displacer, it typically mountson the side of the vessel as shown in figure 2-3. If thesensor has a cageless displacer, the sensor mountson the side or top of the vessel as shown in figure 2-4.

The Type DLC3000 digital level controller is typicallyshipped attached to the sensor. If ordered separately,it may be convenient to mount the digital levelcontroller to the sensor and perform the initial setupand calibration before installing the sensor on thevessel.

NoteCaged sensors have a rod and blockinstalled on each end of the displacerto protect the displacer in shipping.Remove these parts before installingthe sensor to allow the displacer tofunction properly.

NoteIf alternate drainage is provided by theuser, and a small performance loss isacceptable, the instrument could bemounted in 90 degree rotationalincrements around the pilot shaft axis.The LCD meter may be rotated in 90degree increments to accommodatethis.

The digital level controller and torque tube arm areattached to the sensor either to the left or right of thedisplacer, as shown in figure 2-6. This can be changedin the field on the 249 Series sensors (refer to theappropriate sensor instruction manual). Changing themounting also changes the effective action, becausethe torque tube rotation for increasing level, (looking atthe protruding shaft), is clockwise when the unit ismounted to the right of the displacer and counter-clockwise when the unit is mounted to the left of thedisplacer.

2. Slide the access handle to the locked position toexpose the access hole. Press on the back of thehandle as shown in figure 2-5 then slide the handletoward the front of the unit. Be sure the locking handledrops into the detent.

3. Remove the hex nuts from the mounting studs.

4. Position the insulator on the digital level controller,sliding the insulator straight over the mounting studs.

5. Re-install the four hex nuts on the mounting studsand tighten the nuts.

6. Carefully slide the digital level controller with theattached insulator over the shaft coupling so that theaccess hole is on the bottom of the digital levelcontroller.

7. Secure the digital level controller and insulator tothe torque tube arm with four cap screws.

8. Tighten the cap screws to 10 Nm (88.5 lbfin).

Electrical ConnectionsProper electrical installation is necessary to preventerrors due to electrical noise. A resistance between230 and 1100 ohms must be present in the loop forcommunication with a HART-based communicator.Refer to figure 2-10 for current loop connections.

Power Supply To communicate with the digital level controller, youneed a 17.75 volt dc minimum power supply. Thepower supplied to the transmitter terminals isdetermined by the available supply voltage minus theproduct of the total loop resistance and the loopcurrent. The available supply voltage should not dropbelow the lift-off voltage. (The lift-off voltage is theminimum “available supply voltage” required for agiven total loop resistance). Refer to figure 2-11 todetermine the required lift-off voltage. If you know yourtotal loop resistance you can determine the lift-offvoltage. If you know the available supply voltage, youcan determine the maximum allowable loopresistance.If the power supply voltage drops below the lift-offvoltage while the transmitter is being configured, thetransmitter may output incorrect information.The dc power supply should provide power with lessthan 2% ripple. The total resistance load is the sum ofthe resistance of the signal leads and the loadresistance of any controller, indicator, or related piecesof equipment in the loop. Note that the resistance ofintrinsic safety barriers, if used, must be included.

WARNING

To avoid personal injury or propertydamage caused by fire or explosion,remove power to the instrumentbefore removing the digital levelcontroller cover in an area whichcontains a potentially explosiveatmosphere or has been classified ashazardous.

All power to the digital level controller is supplied overthe signal wiring. Signal wiring need not be shielded,but use twisted pairs for best results. Do not rununshielded signal wiring in conduit or open trays withpower wiring, or near heavy electrical equipment. If thedigital controller is in an explosive atmosphere, do notremove the digital level controller covers when thecircuit is alive, unless in an intrinsically safeinstallation. Avoid contact with leads and terminals. Topower the digital level controller, connect the positivepower lead to the + terminal and the negative powerlead to the terminal as shown in figure 2-12 .

Grounding

WARNING

Personal injury or property damagecan result from fire or explosioncaused by the discharge of staticelectricity when flammable orhazardous gases are present. Connecta 14 AWG (2.1 mm2) ground strapbetween the digital level controllerand earth ground when flammable orhazardous gases are present. Refer tonational and local codes andstandards for groundingrequirements.

The digital level controller will operate with the currentsignal loop either floating or grounded. However, theextra noise in floating systems affects many types ofreadout devices. If the signal appears noisy or erratic,grounding the current signal loop at a single point maysolve the problem. The best place to ground the loopis at the negative terminal of the power supply. As analternative, ground either side of the readout device.Do not ground the current signal loop at more than onepoint.

Shielded Wire

Recommended grounding techniques for shielded wireusually call for a single grounding point for the shield.You can either connect the shield at the power supplyor to the grounding terminals, either internal orexternal, at the instrument terminal box shown in figure2-12.

Power/Current Loop Connections

Use ordinary copper wire of sufficient size to ensurethat the voltage across the digital level controllerterminals does not go below 12.0 volts dc. Connect thecurrent signal leads as shown in figure 2-10. Aftermaking connections, recheck the polarity andcorrectness of connections, then turn the power on.

RTD ConnectionsAn RTD that senses process temperatures may beconnected to the digital level controller. This permitsthe instrument to automatically make specific gravitycorrections for temperature changes. For best results,

locate the RTD as close to the displacer as practical.For optimum EMC performance, use shielded wire nolonger than 3 meters (9.8 feet) to connect the RTD.Connect only one end of the shield. Connect the shieldto either the internal ground connection in theinstrument terminal box or to the RTD thermowell.Wire the RTD to the digital level controller as follows(refer to figure 2-12):

Two-Wire RTD Connections

1. Connect a jumper wire between the RS and R1terminals in the terminal box.

2. Connect the RTD to the R1 and R2 terminals.

Three-Wire RTD Connections

1. Connect the 2 wires which are connected to thesame end of the RTD to the RS and R1 terminals inthe terminal box. Usually these wires are the samecolor.

2. Connect the third wire to terminal R2. (Theresistance measured between this wire and either wireconnected to terminal RS or R1 should read anequivalent resistance for the existing ambienttemperature. Refer to the RTD manufacturer’stemperature to resistance conversion table.) Usuallythis wire is a different color from the wires connectedto the RS and R1 terminals.

Communication Connections

WARNING

Personal injury or property damagecaused by fire or explosion may occurif this connection is attempted in anarea which contains a potentiallyexplosive atmosphere or has beenclassified as hazardous. Confirm thatarea classification and atmosphereconditions permit the safe removal ofthe terminal box cap beforeproceeding.

The 375 Field Communicator interfaces with the TypeDLC3000 digital level controller from any wiringtermination point in the 4–20 mA loop (except acrossthe power supply). If you choose to connect the HARTcommunicating device directly to the instrument,attach the device to the loop + and terminals insidethe terminal box to provide local communications withthe instrument.

Test Connections

WARNING

Personal injury or property damagecaused by fire or explosion may occurif the following procedure is attemptedin an area which contains a potentiallyexplosive atmosphere or has beenclassified as hazardous. Confirm thatarea classification and atmosphereconditions permit the safe removal ofthe terminal box cap beforeproceeding.

Test connections inside the terminal box can be usedto measure loop current across an internal 1 ohmresistor.

1. Remove the terminal box cap.

2. Adjust the test meter to measure a range of 0.001to 0.1 volts.

3. Connect the positive lead of the test meter to the +connection and the negative lead to the T connectioninside the terminal box.

4. Measure Loop current as:

Voltage (on test meter) 1000 = milliamps

example:

Test meter Voltage X 1000 = Loop Milliamps

0.004 X1000 = 4.0 milliamperes

0.020 X 1000 = 20.0 milliamperes

5. Remove test leads and replace the terminal boxcover.

Alarm Jumper Each digital level controller continuously monitors itsown performance during normal operation. Thisautomatic diagnostic routine is a timed series ofchecks repeated continuously. If diagnostics detect afailure in the electronics, the instrument drives itsoutput to either below 3.70 mA or above 22.5 mA,depending on the position (HI/LO) of the alarm jumper.

An alarm condition occurs when the digital levelcontroller self-diagnostics detect an error that wouldrender the process variable measurement inaccurate,incorrect, or undefined, or a user defined threshold is

violated. At this point the analog output of the unit isdriven to a defined level either above or below thenominal 4 20 mA range, based on the position of thealarm jumper.

On encapsulated electronics 14B5483X042 andearlier, if the jumper is missing, the alarm isindeterminate, but usually behaves as a FAIL LOWselection. On encapsulated electronics 14B5483X052and later, the behavior will default to FAIL HIGH whenthe jumper is missing.

Alarm Jumper Locations

Without a meter installed:

The alarm jumper is located on the front side of theelectronics module on the electronics side of the digitallevel controller housing, and is labeled FAIL MODE.

With a meter installed:

The alarm jumper is located on the LCD faceplate onthe electronics module side of the digital levelcontroller housing, and is labeled FAIL MODE.

Changing Jumper Position

WARNING

Personal injury or property damagecaused by fire or explosion may occurif the following procedure is attemptedin an area which contains a potentiallyexplosive atmosphere or has beenclassified as hazardous. Confirm thatarea classification and atmosphereconditions permit the safe removal ofthe instrument cover beforeproceeding.

Use the following procedure to change the position ofthe alarm jumper:

1. If the digital level controller is installed, set the loopto manual.

2. Remove the housing cover on the electronics side.Do not remove the cover in explosive atmosphereswhen the circuit is alive.

3. Set the jumper to the desired position.

4. Replace the cover. All covers must be fullyengaged to meet explosion proof requirements. ForATEX approved units, the set screw on the transducerhousing must engage one of the recesses in the cover.

Loop Test (2 2) (optional)Loop test can be used to verify the controller output,the integrity of the loop, and the operations of anyrecorders or similar devices installed in the loop. Toinitiate a loop test, perform the following procedure:1. Connect a reference meter to the controller. To doso, either connect the meter to the test connectionsinside the terminal box (see the Test Connectionsprocedure) or connect the meter in the loop as shownin figure 2-10.2. From the Online menu, select Diag/Services, andLoop Test, to prepare to perform a loop test.

3. Select OK after you set the control loop to manual.

The Field Communicator displays the loop test menu.

4. Select a discreet milliamp level for the controller tooutput. At the “Choose analog output” prompt, select 4 mA, 20 mA, or Other to manually input a valuebetween 4 and 20 milliamps.

5. Check the reference meter to verify that it reads thevalue you commanded the controller to output. If thereadings do not match, either the controller requires anoutput trim, or the meter is malfunctioning.

After completing the test procedure, the display returnsto the loop test screen and allows you to chooseanother output value or end the test.

Basic Setup and Calibration

September 2005 3-1

3-3 3Initial Setup If a Type DLC3010 digital level controller ships fromthe factory mounted on a 249 Series sensor, initialsetup and calibration is not necessary. The factoryenters the sensor data, couples the instrument to thesensor, and calibrates the instrument and sensorcombination.

NoteIf you received the digital levelcontroller mounted on the sensor withthe displacer blocked, or if thedisplacer is not connected, theinstrument will be coupled to thesensor and the lever assemblyunlocked. To place the unit in service,if the displacer is blocked, remove therod and block at each end of thedisplacer and check the instrumentcalibration. (If the “factory cal” optionwas ordered, the instrument will beprecompensated to the processconditions provided on the requisition,and may not appear to be calibrated ifchecked against room temperature 0and 100% water level inputs).If the displacer is not connected, hangthe displacer on the torque tube, andre-zero the instrument by performingthe Mark Dry Coupling procedure.If you received the digital levelcontroller mounted on the sensor andthe displacer is not blocked (such asin skid mounted systems), theinstrument will not be coupled to thesensor, and the lever assembly will belocked. To place the unit in service,unlock the lever assembly and couplethe instrument to the sensor. Thenperform the Mark Dry Couplingprocedure.

To review the configuration data entered by thefactory, connect the instrument to a 24 volt dc powersupply as shown in figure 2-10. Connect the 375 Field

Communicator to the instrument and turn it on. Fromthe Online menu select Review, then select DeviceParams (Device Parameters). You can then pagethrough the configuration data using the NEXT andPREV keys. If your application data has changedsince the instrument was factory-configured, refer tothe menu tree at the beginning of this quick start guidefor paths to the appropriate parameters.For instruments not mounted on a level sensor orwhen replacing an instrument, initial setup consists ofentering sensor information. The next step is couplingthe sensor to the digital level controller. When thedigital level controller and sensor are coupled, thecombination may be calibrated.Sensor information includes displacer and torque tubeinformation, such as:

Length units (meters, inches, or centimeters)

Volume units (cubic inches, cubic millimeters, ormilliliters)

Weight units (kilograms, pounds, or ounce)

Displacer Length

Displacer Volume

Displacer Weight

Displacer Driver Rod Length (moment arm) (seetable 3-1)

Basic Setup and Calibration

September 2005 3-3

3. You are asked to select the measurementapplication (level, interface, or density).

NoteFor interface applications, if the 249 isnot installed on a vessel, or if the cagecan be isolated, calibrate theinstrument with weights, water, orother standard test fluid, in levelmode. After calibrating in level mode,the instrument can be switched tointerface mode. Then, enter the actualprocess fluid specific gravity(s) andrange values.If the 249 sensor is installed and mustbe calibrated in the actual processfluid(s) at operating conditions, enterthe final measurement mode andactual process fluid data now.

a. If you choose “Level” or “Interface,” the defaultprocess variable units are set to the same unitschosen for displacer length. The default upperrange value is set to equal the displacer length andthe default lower range value is set to zero.

b. If you choose “Density,” the default processvariable units are set to “SGU” (Specific GravityUnits). The default upper range value is set to “1.0”and the default lower range value is set to “0.1”.

4. You are asked, “Do you wish to make theinstrument direct or reverse acting?”Choosing “reverse acting” will swap the default valuesof the upper and lower range values (the processvariable values at 20 mA and 4 mA). In a reverseacting instrument, the loop current will decrease as thefluid level increases.5. You are given the opportunity to modify the defaultvalue for the process variable engineering units.6. You are now given the opportunity to edit thedefault values that were entered for the upper rangevalue (PV Value at 20 mA) and lower range value (PVValue at 4 mA).

NoteIf Setup Wizard aborts on step 6, clearthe Level Offset parameter beforerestarting Setup Wizard.

7. The default values of the alarm variables will be setas follows:

Direct-Acting Instrument (Span = Upper Range Value LowerRange Value

Alarm Variable Default Alarm ValueHi-Hi Alarm Upper Range ValueHi Alarm 95% span + Lower Range ValueLo Alarm 5% span + Lower Range ValueLo-Lo Alarm Lower Range Value

Reverse-Acting Instrument (Span = Lower Range Value UpperRange Value

Alarm Variable Default Alarm ValueHi-Hi Alarm Lower Range ValueHi Alarm 95% span + Upper Range ValueLo Alarm 5% span + Upper Range ValueLo-Lo Alarm Upper Range Value

The PV alarm deadband is set to zero.The process variable alarms are all disabled.8. You are asked if temperature compensation is tobe used.

a. If you select “No Temperature Compensation”

If Density mode was chosen, the Setup Wizard iscomplete.

If specific gravity temperature compensationtables exist in the instrument, you will be asked if it’sok to overwrite them with single values.

You are prompted to enter the specific gravity ofthe process fluid (if interface mode, the specificgravities of the upper and lower process fluids).

NoteIf you are using water or weights forcalibration, enter a specific gravity of1.0 SGU. For other test fluids, enter thespecific gravity of the fluid used.

b. If you select “Temperature Compensation”

Two data specific gravity tables are available that maybe entered in the instrument to provide specific gravitycorrection for temperature (refer to the Detailed Setupsection of the instruction manual). For interface levelapplications, both tables are used. For levelmeasurement applications, only the lower specificgravity table is used. Neither table is used for densityapplications. Both tables may be edited during detailed

DLC3000 Series

setup. The Setup Wizard asks if the tables should beused. If not, then you must supply a “single point”specific gravity value (two “single point” values for aninterface application).

NoteThe existing tables may need to beedited to reflect the characteristics ofthe actual process fluid.

If Density mode was NOT chosen, you will bepresented with the current specific gravity temperaturecompensation table (or lower fluid specific gravitytemperature compensation table if interfaceapplication) for editing. You can accept the currenttable(s), modify an individual entry, or enter a newtable manually. For an interface application, you canswitch between the upper and lower fluid tables.

You are prompted to choose a torque tubematerial. The instrument loads the default torque tubetemperature compensation table for the materialchosen. If you choose “Unknown” for the material, theK Monel temperature compensation table is loaded. Ifyou choose “Special” the current table in theinstrument will be left unchanged, but the label for thematerial is changed to “Special”. This feature allows aspecial user table to be retained without overwriting,but does not allow it to be copied to a storedconfiguration.

You are presented with the torque-tubetemperature compensation table for edit. You canaccept the table, edit an individual table entry, load atemperature compensation table for a different torquetube material, or enter a new table manually. If atemperature compensation table for a differentmaterial is chosen, the torque tube material will beupdated to reflect the new material chosen. If a newtable is entered manually, or an individual entry ismodified, then the torque tube material will bechanged to “Special.”

NoteIn firmware version 07 and 08, the datatables for torque-tube correction aresimply stored without implementation.You may use the information topre-compensate the measuredtorque-tube rate manually.

Coupling After entering the sensor information, the SetupWizard prompts you to couple the digital levelcontroller to the sensor. If not already coupled,perform the following procedure to couple the digitallevel controller to the sensor.1. Slide the access handle to the locked position toexpose the access hole. Press on the back of thehandle as shown in figure 2-5 then slide the handletoward the front of the unit. Be sure the locking handledrops into the detent.2. Set the displacer to the lowest possible processcondition, (i.e. lowest water level or minimum specificgravity) or replace the displacer by the heaviestcalibration weight.

NoteInterface or density applications withdisplacer/torque tube sized for a smalltotal change in specific gravity aredesigned to be operated with thedisplacer always submerged. In theseapplications, the torque rod issometimes resting on a stop while thedisplacer is dry. The torque tube doesnot begin to move until a considerableamount of liquid has covered thedisplacer. In this case, couple with thedisplacer submerged in the fluid withthe lowest density and the highestprocess temperature condition, or withan equivalent condition simulated withthe calculated weights.If the sizing of the sensor results in aproportional band greater than 100%(total expected rotational span greaterthan 4.4 degrees), couple thetransmitter to the pilot shaft while atthe 50% process condition to makemaximum use of available transmittertravel (6). The Mark Dry Couplingprocedure is still performed at the zerobuoyancy (or zero differentialbuoyancy) condition.

3. Insert a 10 mm deep well socket through theaccess hole and onto the torque tube shaft clamp nut.Tighten the clamp nut to a maximum torque of 2.1 Nm(18 lbfin).4. Slide the access handle to the unlocked position.(Press on the back of the handle as shown in figure2-5 then slide the handle toward the rear of the unit.)Be sure the locking handle drops into the detent.

Calibration

Quick Calibration

The following procedure may be used to calibrate theinstrument as an analog transmitter replacement. Theoutput 4 and 20 mA conditions will be related to agiven pair of mechanical input conditions only, the PVin engineering units will not be calibrated. Thisapproach will give satisfactory results for many of thesimple level measurement applications encountered.

NoteThis procedure assumes that you areusing the instrument in LevelMeasurement Mode, even if theprocess is interface or density.The SG value used for Level is theactual fluid SG. The SG value used forInterface is the difference between theSG of the upper and lower fluids. TheSG value entered for Density would bethe difference between the minimumand maximum density range of theapplication.

1. Connect a 24 V dc supply and make sure there isbetween 230 and 1100 Ohms series resistance in theloop. Hook up a 375 Field Communicator (or otherHART master) across the instrument terminals oracross the series resistor and establishcommunications with the transmitter.

2. Enter the mounting sense (4-1-1-1-2), then SEND.

3. Set Level Offset (3-3-3) to zero; then SEND.

4. Set PV is (3-3-6) to LEVEL, then SEND.

5. Set Specific Gravity (3-3-5) to the differencebetween SGs of the upper and lower fluids.

6. Set up the lowest process condition (or hang aweight equal to the displacer weight minus theminimum buoyancy).

7. Couple to the 249 Series transmitter sensor andclose the access door (this unlocks the leverassembly).

8. Mark Dry-Coupling (3-2-1) point (this marks zerodifferential buoyancy).

9. Set Zero (3-3-2-5-1).

10. Set up the highest process condition (or hang aweight equal to the displacer weight minus themaximum buoyancy).11. Set Span (3-3-2-5-2).12. Set Meter Type to % Range Only (4-2-2-2-3).13. The instrument is calibrated stop here. Do notproceed to Detailed Calibration.

Detailed Calibration

PV Sensor CalibrationIf the advanced capabilities of the transmitter are to beused, it is necessary to calibrate the PV sensorinstead of using the Quick Calibration (“zero andspan”) approach.

Sensor Calibration Using LiquidsLevel Application—with standard displacer andtorque tube, using a single test fluid

Standard practice is to initially calibrate the system atfull design span to determine the sensitivity of thesensor/transmitter combination. (This practice hastraditionally been called “matching”). The data isrecorded in the transmitter non-volatile memory. Theinstrument may then be set up for a target fluid with agiven specific gravity by changing the value of SG inmemory. The value of SG in the instrument memoryduring the calibration process should match the SG ofthe test fluid being used in the calibration.1. From the Online menu select: Basic Setup, PVSetup, Level Offset (3-3-3). Set Level Offset to 0.00,press ENTER and SEND.

2. Run through Setup Wizard (3-3-1) and verify thatall sensor data is correct.

Select Application = Level, Direct Action. Use No temperature compensation.Enter SG = 1.0 (for water) or actual SG of of test

fluid if different than 1.03. After completing the Setup Wizard, raise the testfluid level to the process zero point (e.g.: up to thecenterline of the lower side equalizing connection, halfthe displacer length below the center-of-float mark,etc.) From the Online menu select: Basic Setup,Sensor Calibrate, Mark Dry Coupling (3-2-1). Followall prompts.4. Fill the cage with test liquid almost to the top of thedisplacer. From the Online menu select: Basic Setup,Sensor Calibration, Single Point (3-2-4). Follow theprompts and enter the actual test liquid level in thecurrently selected engineering units.5. Adjust the test fluid level and check the instrumentdisplay and current output against external level at

several points to verify the level calibration. If thedisplay is slightly inaccurate:

a. For bias errors, try re-marking the coupling pointat the zero level condition.

b. For gain errors, try using the two-point sensorcalibration to trim the torque tube rate. Use twoseparate fluid levels on the displacer, separated byat least 10 inches.

After the calibration, edit the SG parameter (3-3-5) toconfigure the instrument for the target process fluid.The sensor is calibrated.

Interface Application—with standard displacerand torque tube

This procedure assumes that process temperature isnear ambient temperature and that the displacer is notoverweight for the torque tube. If these assumptionsare not correct for your installation, refer to theoverweight displacer procedures in this section or theTemperature Compensation information in theinstruction manual. First, use the standard sensorcalibration procedure under the previous heading,Level Application—with standard displacer and torquetube using a single test fluid. Proceed with step 6.

6. When the single liquid level is as accurate as youcan get it, set up or simulate the zero interface levelcondition. E.g.: Bring the actual lower process fluid tothe zero interface level position and fill the rest of thecage with the actual lighter upper process fluid. Anequivalent weight or computed water level can beused as an alternative.

The output in % should now be approximately:

100 * SGupperfluid / SGlowerfluid

From the Online menu, select: Basic Setup, PV Setup,PV is, (3-3-6). (Note: if the PV is parameter has beenset to density, the menu selection for PV is will be3-3-4.) Select Interface, press ENTER and SEND.

7. From the PV Setup menu (where you should beafter finishing the PV is selection), select the SpecificGravity menu. Use the single point entry method, andenter the SG of the lower fluid and the SG of theupper fluid, respectively, at the prompts.

8. If you are using the actual upper fluid, make surethe displacer is completely covered.

If you are simulating the upper fluid with water, you willneed to fill the cage to SGupperfluid times displacerlength (plus a little extra to account for the amount thatthe displacer rises because of the increase inbuoyancy).

NoteInformation on computing precisesimulation of this effect is available inthe Supplement to 249 Series SensorsInstruction Manual Form 5767 (partnumber D103066X012). Contact yourFisher sales office for information onobtaining this manual supplement.

From the Online menu, select: Basic Setup, SensorCalibrate, Trim PV Zero (3-2-5).

Enter 0.0 inches. This will trim out the displacer risecorrection at the minimum buoyancy condition. (Checkthe Level Offset variable, to see how much correctionwas made. If the Level Offset exceeds 20% ofdisplacer length, there may be problems when usingDeltaV [see the notes on pages 3-8 and 3-9regarding DeltaV interaction]. However, the fraction ofan inch that is trimmed out here will not hurt.) Thisstep is taken to make sure that a 4 mA output will beproduced at the lowest measurable process condition.Since the output will not change any more for interfacelevels dropping below the bottom of the displacer, wearbitrarily re-label that point as zero. An alternativeapproach is to adjust the range values slightly to get 4mA out at the lowest possible computed PV.9. The sensor is calibrated. Check output againstinput to validate reconfiguration to Interface mode.

Interface Application—with an overweightdisplacer

An interface application can be mathematicallyrepresented as a level application with a single fluidwhose density is equal to the difference between theactual fluid densities. We take advantage of this factwhen the sensor sizing prevents the transmitter frombeing able to observe the actual zero buoyancycondition (i.e., the linkage is lying on a travel stop atthe dry displacer condition).1. From the Online menu, select; Basic Setup, PVSetup (3-3).

2. Set Level Offset (3-3-3) to zero.3. Set the range values (3-3-2) to: LRV = 0.0, URV =displacer length.4. Mark the coupling point at lowest process condition(displacer completely submerged in the upperfluid NOT dry).5. Set PV is (3-3-6) to Level6. Set Specific Gravity (3-3-5) to the differencebetween the 2 fluid SGs. (For example, if SG upper =

3

Basic Setup and Calibration

September 2005 3-7

0.87 and SG lower = 1.0, the specific gravity to enteris 0.13).

7. Use any of the sensor calibration methods tocalibrate torque tube rate, but use actual processfluids, or use a single test fluid to set up buoyancyconditions simulating the process conditions you arereporting to the instrument. From the Online menuselect: Basic Setup, Sensor Calibrate (3-2).

NoteInformation on simulating processconditions is available in theSupplement to 249 Series SensorsInstruction Manual Form 5767 (partnumber D103066X012). Contact yourFisher sales office for information onobtaining this manual supplement.

8. If the zero is off, set up the zero condition againand repeat the Mark Dry Coupling procedure. Do notuse Trim PV Zero.

Following are some guidelines on the use of thevarious sensor calibration methods when theapplication uses an overweight displacer:

Weight-based: Use two accurately known weightsbetween minimum and maximum buoyancyconditions. The full displacer weight is invalid becauseit will put the unit on a stop.

Wet/dry: “Dry” now means submerged in lightest fluidand “wet” means submerged in the heaviest fluid.

Single-point: Set up any valid process condition thatyou can independently measure, (other than thecondition that matches the coupling point). The higherthe data point is, the better the resolution will be.

Two-point: Use any two interface levels that actuallyfall on the displacer. Accuracy is better if the levels arefarther apart. The result should be close if you canmove the level even 10%.

Density Applications with standard displacerand torque tube.

NoteYou will need to select PV Units whenchanging from level or interface todensity. After sending the info, it isnecessary to back out of the handheldmenu that shows SG SP and LevelOffset, and then re-enter that menuand select Range Values. The rangevalues will need to be edited toprovide reasonable magnitudes in thenew unit system.

If the displacer is overweight, there is no way to getthe output numerically correct in density mode,because the Level Offset is not available. Therefore,density calibration normally has to begin with theassumption that the displacer is free moving at zerobuoyancy (dry) conditions. “Mark” the coupling pointaccurately at the dry displacer condition. Then any ofthe four sensor calibration methods (weight-based,wet/dry, single-point, or two-point) can be used indensity mode. However, the terminology can beconfusing, because it usually refers to a “level” as theprocess condition to set up. When using one of thesemethods, remember that you are in the density modeand enter observed PV in current units of SGU, g/L,lb/in3, kg/m3, etc.Weight Based: The weight based method asks youfor the lowest and highest density you want to use forthe calibration points, and computes weight values foryou. If you can’t come up with the exact values it asksfor, you are allowed to edit the values to tell it whatweights you actually used.Wet/dry: The wet/dry method essentially reverts tolevel mode during the calibration process. It asks forthe SG of your test fluid first. Then, it has you set upfirst a dry and then a completely submerged displacercondition.Single-point: When using the single-point calibration,you must report the density condition in current PVunits when it asks you for the “level” in current PVunits. The precondition for single-point calibration towork is that the coupling point was previously“marked” at the zero buoyancy state.Two-point: The two-point calibration method requiresyou to set up two different process conditions, with asmuch difference as possible. You could use twostandard fluids with well-known density and alternatelysubmerge the displacer in one or the other. If you are

going to try to simulate a fluid by using a certainamount of water, you have to remember that theamount of displacer covered by the water is whatcounts, not the amount in the cage. The amount in thecage will always need to be slightly more because ofthe displacer motion. Because of this inconvenience,and the extra work of draining and flooding with twofluids, the two-point calibration method is probably theleast attractive in density mode.

Note: These calibration methods advise you to trim PVzero for better accuracy. That command is notavailable in density mode.

Sensor Calibration at Process Conditions (HotCut-Over) when input cannot be varied

If the input to the sensor cannot be varied forcalibration, you can configure the instrument gainusing theoretical information and trim the output offsetto the current process condition. This allows you tomake the controller operational and to control a levelaround a setpoint. You can then use comparisons ofinput changes to output changes over time to refinethe gain estimate. A new offset trim will be requiredafter each gain adjustment. This approach is notrecommended for a safety-related application, whereexact knowledge of the level is important to prevent anoverflow or dry sump condition. However, it should bemore than adequate for the average level-controlapplication that can tolerate large excursions from amidspan set point.

There are a number of calibration methods available inthe DLC3000 Device Description. Two-point calibrationallows you to calibrate the torque tube using two inputconditions that put the measured interface anywhereon the displacer. The accuracy of the methodincreases as the two points are moved farther apart,but if the level can be adjusted up or down even a fewinches, it is enough to make a calculation. Most levelprocesses can accept a small, manual adjustment ofthis nature. If your process cannot, then the theoreticalapproach is the only method available.

NoteThis approach is not recommended foruse with DeltaV. It results in a largevalue being entered in the Level Offsetparameter, which can trigger arecursive attempt to write range valuesto the digital level controller after acommunications glitch. Thenon-volatile memory write-cycle life inthe instrument will be exhaustedrapidly.

1. Determine all the information you can about the249 hardware: 249 type, mounting sense (controller tothe right or left of displacer), torque tube material andwall thickness, displacer volume, weight, length, anddriver rod length. (Driver rod length is called “DispRod” in the DD menus. It is not the suspension rodlength, but the horizontal distance between thecenterline of the displacer and the centerline of thetorque tube). Also obtain process information: fluiddensities, process temperature, and pressure. (Thepressure is used as a reminder to consider the densityof an upper vapor phase, which can becomesignificant at higher pressures.)2. Run the Setup Wizard and enter the various datathat is requested as accurately as possible. Set theRange Values (LRV, URV) to the PV values whereyou will want to see 4 mA and 20 mA output,respectively. These might be 0 and 14 inches on a 14inch displacer.3. Mount and couple at the current process condition.It is not necessary to run the Mark Dry Couplingprocedure, because it stores the current torque tubeangle as the zero buoyancy condition, and willtherefore not be accurate.4. With the torque tube type and material information,find a theoretical value for the composite or effectivetorque tube rate, (Refer to the Entering TheoreticalTorque Tube (TT) Rates procedure in this section),and enter it in the instrument memory. The value can

be accessed in the Review Menu under FactorySettings.

5. If the process temperature departs significantlyfrom room temperature, use a correction factorinterpolated from tables of theoretical normalizedmodulus of rigidity. Multiply the theoretical rate by thecorrection factor before entering the data. You shouldnow have the gain correct to within perhaps 10%, atleast for the standard wall, short length torque tubes.(For the longer torque tubes (249K, L, N) with thin-walland a heat insulator extension, the theoretical valuesare much less accurate, as the mechanical pathdeparts considerably from the linear theory.)

NoteTables containing information ontemperature effects on torque tubescan be found in the Supplement to 249Series Sensors Instruction Manual Form 5767 (part number D103066X012).Contact your Fisher sales office forinformation on obtaining this manualsupplement.

6. Now using a sight glass or sampling ports, obtainan estimate of the current process condition. Run theTrim PV Zero procedure and report the value of theactual process in the PV engineering units. (forexample, sight glass reads 11 inches.) The instrumentwill compute an offset to trim out the differencebetween your value and it’s calculation, and store it inthe Level Offset parameter.

7. You should now be able to go to automatic control.If observations over time show the instrument outputexhibits, for example,1.2 times as much excursion asthe sight glass input, you could divide the storedtorque tube rate by 1.2 and send the new value to theinstrument. Then run another Trim PV Zero procedureto correct the offset, and observe results for anotherextended period to see if further iteration is required.

Entering Theoretical Torque Tube (TT) Rates

The Supplement to 249 Series Sensors InstructionManual, Form 5767, provides the theoreticalcomposite torque tube (TT) rate for 249 Seriessensors with Type DLC3010 controllers. Thesenumbers are nominal values. They should be within10% of the values that the instrument would computewhen you perform a sensor calibration. They will beless accurate for the long torque tubes (Type 249K, L,N, V, and P), especially with thin-wall constructions.If you are unable to perform a sensor calibrationduring installation, you may enter the values into theinstrument at the following menu item in the handheld:Review, Factory Settings, TT rate (5-4-1)Then, manually set the LRV and URV to the PVvalues at which you desire 4 and 20 mA output,respectively.Basic Setup, PV Setup, PV Range, URV LRV(3-3-2-2)Next, perform a Trim PV Zero operation to align theinstrument output with the sight glass reading.Basic Setup, Sensor Calibrate, Trim PV Zero (3-2-5)These steps will provide an approximate PVcalibration to get a system operational. Furtherrefinements can then be made when it is possible tomanipulate and observe the level and instrumentoutput.

NoteThis approach is not advised whenusing the HART interface in a DeltaVinstallation, because the computedLevel Offset can exceed 20% ofdisplacer length, making one of therange values appear invalid during theDeltaV initialization process. This canlead to repetitive re-initializationattempts, using up the write-cycle lifeof the instrument NVM.

Minimum Differential Specific GravityWith a nominal 4.4 degrees torque tube shaftrotation for a 0 to 100 percent change in liquid level(specific gravity=1), the digital level controller canbe adjusted to provide full output for an input rangeof 5% of nominal input span. This equates to aminimum differential specific gravity of 0.05 withstandard volume displacers.See 249 Series sensor specifications for standarddisplacer volumes and standard wall torque tubes.Standard volume for 249C and 249CP series is∼980 cm3 (60 in3), most others have standardvolume of ∼1640 cm3 (100 in3).Operating at 5% proportional band will degradeaccuracy by a factor of 20. Using a thin wall torquetube, or doubling the displacer volume will eachroughly double the effective proportional band.When proportional band of the system drops below50%, changing displacer or torque tube should beconsidered if high accuracy is a requirement.
