Section 1: Introduction1.1 System Description The instructions in this manual are for the Drexelbrook
509-7X-XXXSeriesUniversalIII™forlevelmeasurementinliquids,slurries,interfacesandgranulars.
Each Drexelbrook 509-7X-XXX system consists of aUniversal III™ (409-1000) series two-wire, 4-20 mAelectronicunitanda700seriessensingelement(probe).A380seriesconnectingcableisalsosuppliedforconnectionofthesensingelementtotheelectronicunit.

1.2 Technology In a simple capacitance probe, when the level rises and

There are drawbacks, however, especiallywhenthereiscoatingoftheprobe.

Use only if the process material isgreter than 1000 uMHOS/cm such as acidsand caustic.
AGROUND RODA ground rod can be fabricated out of anymetal compatible with the process. Usematerial that is at least 3/8inch dia. such aspipe, All-Thread, or tubing. The ground rodmust be parallel and relatively close to thesensor.
BGROUND WIRE1/4 inch or larger dia. stainless steel ropethat is anchored or weighted can be used.
ESUBMERGED METAL STRUCTUREUse any constantly submerged metalobject such as: pumps, agitators, orthermowells.
FMETAL FLANGEA submerged metal flange or orifice platecan be used.Use only if the process material is greaterthatn 1000 uMHOS/Cm. such as acids andcaustic.
DMETAL PIPINGMetal piping that connects to the tankbottom can be used as a groundreference. Use only if the process materialis greter than 1000 uMHOS/cm such asacids and caustic.
If the vessel is non metallic see grounding sketch below. sensorswith factory supplied concentric shield or ground rod do not needadditional grounding.
Measure ground continuity from housing ground screw to metalwall of vessel. A good ground will measure less than 5 ohms.

Make surethat conduits entering and leaving the housing havea good electrical ground connection to the housingIf the recommendations listed are followed, it is usuallynot necessary to add RFI filtering to protect against signalstrengthsof10Volts/Meterorless.Thisdegreeofprotection is usually sufficient to protect against walkie talkies that are used 3 feet (1M) or more from a typicalelectronic unit. If greater protection is required, or filters have already been provided, install RFI filters as shown in Figure 2-14.

In applications such as desalters or treaters and othercoalescers with electrostatic grids, it is customary forDrexelbrook to supply a special filter on the sensing element. The purpose of the filter is to remove voltage that may be imposed inthesensor fromthehighvoltagegrids.Someearlier applications have the filter located at the transmitter instead of the sensing element; either is acceptable.Connect the electrostatic filter Drexelbrook Part Number 385-0028-004asshowninFigure 2-15.

It is permissible or sometimes even recommended thatbothmethodsbeused in order to establisha calibrationstandard. For example, if the vessel was already filled before the calibration was attempted and it is difficult or impossibletolowertheleveltoestablishthesecondpoint,it would be best to use a calculated zero capacitance for the lowpointandactual level for thehighpoint.While thiswouldn’tbeasaccurateastwoknownlevelpoints,itwillbereasonablyaccurateuntilanactuallowpointcalibrationcanbeestablished. TheServicedepartmentwillhelp incalculatinghighorlowcapacitancevalues.
Because calibration involves determining two knownpoints of capacitance, a span (or range) jumperprovidesanadjustment for the change in capacitance required toproducefullscalecurrent.

3.12 Digital Integral Meter Configuration
TheoptionalDigitalIntegralMeter(DIM)(401-44-3)isusedforlocaldisplay.Itcanbeviewedthroughaglassviewportinthetransmitterhousingcover.See Figure 2-16
The meter can be configured to read any engineering units, e.g.4-20mA,gallons,inches,feet,etc.Statusmessagesarealsodisplayedonthemeter.RefertoSection2.9formeterinstallation.
To configure the meter, "Click" on Configure Meter inmenuscreenforthepop-up;
The meter is configured by: • setting the minimum value equal to the value to be
displayedattheLRVand,• setting the maximum value equal to the value to be
displayedattheURV. Factory default settings are: MinimumValue=0.00 MaximumValue=100.00 To set the meter display range equal to calibration
range: MinimumValue=LRV MaximumValue=URV To set the meter display range equal to percent of
level: MinimumValue=0 MaximumValue=100 Whenasmarttransmitterispowereddownortheribbon

3.14.1 Validation Design Concept
Smart RF Continuous Level systems derive their inputinformation from a sensing element that providesa capacitance value to the RF Transmitter. The RFTransmitteroutputsignalisderivedfromthiscapacitancevalue, based on the capacitance span of the transmitterduringinitialcalibration.
If the RF Transmitter's minimum and maximumcapacitancevaluesareknown,andremainunchanged,theeffects of a specific capacitance value within this range can beaccuratelypredicted.Ifaknowncapacitance(whichcanbeNIST-traceable)withinthisrangeproducesrepeatableresults and the minimum and maximum values remainunchanged the RF Level system can be assumed to beoperatingcorrectly.
With a known capacitance input, the output signalwouldnotbe repeatable if the calibration information isaltered,oriftheRFtransmitterwasnotoperatingwithinspecifications. Repeatable calibration information can be maintained through the use of the Save/Print capabilitybuiltintotheUniversalIIITransmitter.

3.14.2 Validation Procedures
A. Drexelbrook Laptop software must be used. Connectthe laptop to the smart level transmitter signal looptobevalidatedandstartthesoftwareaccordingtotheinstructionsprovidedatthebeginningofthisSection.
B. At the Main configuration screen observe the Level Calibration,LowerCapacitance,andUpperCapacitancevalues and the Lower Level and Upper Level values.SelectanNPOCapacitor(whichcanbeNISTtraceable,ifdesiredorrequired)thatfallssomewheremid-range.Example: See Fig. 3-18. If Lower Capacitance is 50pF andUpperCapacitanceis2000pF,thatcorrespondstoaLowerLevelandUpperLevelof0-10feet.SelectanNPOCapacitorofapproximately1000pF.[Drexelbrook401-6-8CapacitorSubstituteBoxmayalsobeused;itistraceabletoNIST].
C. Connect the NPO capacitor selected from the laststep to the Probe and Ground connections at thetransmitter (with coaxial cable from sensing elementdisconnected).
D. SelectRealTimeViewonthePCsoftwareMenuScreen(F4onyourkeyboard)SeeFig.3-19.ThedisplayshouldshowtheCapacitanceasthevalueoftheNPOCapacitor(within the capacitors tolerance), and the LEVELshoulddisplayclosetothemid-rangeoftheLowerandUpper Level from the Level Calibration field. The Loop Current and the Percentage will also reflect the values thataregeneratedbytheNPOCapacitor.Addto thescratchpadoftheMenuScreenthevalueoftheNPOcapacitorthatyouused.Ifdesired,thisinformationcanbe printed out for file or record purposes. Mark or Tag this capacitor* to correspond to this specific transmitter. Putthecapacitorinasafelocationforuseinsubsequenttestingandvalidation.
E. By placing the same exact capacitor* on the RFtransmitter'sProbeandGroundterminalsandobservingthesignaloutputgeneratedbythiscapacitor,itcanbeverified that the transmitter is operating properly and thatthecalibrationinformationisthesameasduringtheinitialsetup.
Every capacitor manufactured will generate a slightlydifferent capacitance value within its specified tolerance. BymarkingthecapacitorandusingonlythiscapacitorfortestingandvalidatingtheAMETEKDrexelbrookUniversalIII Transmitter, the system should produce repeatableresults within transmitter specifications.

4.3 Configuration (Continued)
509-7X Series Universal III™ Transmitter
4.4 Calibration
There are two methods of calibrating the UniversalIII transmitter: Point Calibration or Capacitance Calibration.
Point calibration uses the actual level in your vessel forcalibration.The furtherapart the twopointsare for thecalibration, then the better the accuracy of the overallmeasurement.
Capacitance calibration uses values obtained from theDrexelbrookServicedepartment(orapreviouscalibrationor identical application) for the zero and span calibration data. Call 1-800-527-6297 for assistance. Please providethe purchase order number, transmitter serial numberandapplicationinformationtotheServiceEngineer.
It is permissible or sometimes even recommended thatbothmethodsbeused in order to establisha calibrationstandard. For example, if the vessel was already filled before the calibration was attempted and it is difficult or impossibletolowertheleveltoestablishthesecondpoint,it would be best to use a calculated zero capacitance for the lowpointandactual level for thehighpoint. Whilethis wouldn’t be as accurate as two known level points,it will be reasonably accurate until an actual low pointcanbeestablished. TheServicedepartmentwillhelp incalculatinghighorlowcapacitancevalues.

4.4.4 Strapping Table
Thestrappingtableisa2-pointto21-pointtableusedbythe Universal III to cause output current to follow specified relationship to level. There are certain strapping tablesthatarealreadybuiltintothetransmittersoftware.Theseare: Linear (vertical tank); Horizontal Tank with flat ends; Horizontal Tank with dished ends; Horizontal Tank with hemispherical ends; and Spherical Tank. These predefined tablesareautomaticallycreatedbyselectionsmadewithVessel Config assignment during Configuration procedure inSection4.3.
If output-to-level relationship is not defined by one of these
tables,youmaycreateatableinStrappingTableprogram.Tocreateanon-linearrelationship,youwillneedatleast3pointsandmayuseasmanyas21points.A21-pointtablewill define relationship to about a 0.1% accuracy. Common exampleforasimpletablewouldbeConeBottomVerticaltank which would require 3 points—bottom, straight-side break point, and top. Open channel flow application, however, could benefit from using all 21 available points.
• Plan your table by filling out form below. You may use first column which lists every 5% between 0 and 100%, or you may fill in your own values in column 2.

Section 5: Configuration and Calibration Using the Rosemount™ Model 275 Communicator without a Drexelbrook Device Description
The Model 275 Communicator can be used to enter anddownload configuration/ calibration values to the Universal IIItransmitter.
5.1 Range / Span Control
Definitions: • LRV-LowerRangeValueofcontrolloop.• LSL -LowerSensorLimitrelatedtominimumlevelpoint.• PV -ProcessVariable;levelvaluefromtransmitter.• SV -SecondaryVariable;volumeorweight,basedonPV.• URV-UpperRangeValueofcontrolloop.• USL-UpperSensorLimitrelatedtomaximumlevelpoint.
The first step in configuration is to identify the span range positionoftheinstrument.Thereisajumperonthebackof the electronics chassis: Range Span See Fig. 5-1. The RangeSpanprovidescontinuousadjustmentofthechangein capacitance required to produce full scale current.Each Range Span position advances the range in inchesor feet to approximately five times the previous setting. Table 5-1 gives the range span position for a number ofcommonsensingelementsandrangeofmeasurement.

Application-related Problems
Comments
Product Bridging When process material fills what was originally airspace between the sensor and a nozzle or the vessel, it no longer behaves like a coating. It measures like actual level. Contact Drexelbrook.
Corrosion of metal parts TFE and stainless steel in the sensor's pressure seal have widely different coefficients of expansion that sometimes permit pressure leaks to occur. Re-torqueing the packing assembly can usually fix the problem. Contact the Service department for the proper torque values and procedure.

6.2 Troubleshooting Loop Connection
Specific transmitter loop connections will vary from installationtoinstallationbutingeneralwillbeconnectedinasimilarmannertotypicaltransmitterloopinFigure 4-1.Whentroubleshootingtheloopconnection,verifythefollowingitems.
•Loopdevicesarewiredinseries.
•Thereisatleast250ohmstotalloopresistance.
• There isat least12Vdcavailable for the transmitterwhen a loop current of 20 mA is flowing.
Troubleshooting
Is loopcurrent between3.7 and 22 mA?
Is there aminmum of 250
ohms loopresistance?
1. Check calibrator connections to loop per loop drawing Figure 4-1.2. Check for "noise" and ripple on loop with oscilloscope. Maximum noise level per HART Foundation is 1.2 mV rms (500 - 10 kHz). Maximum ripple (47 - 125 hZ) specification is .2V p-p. Line noise can sometimes be traced to things like motor speed controller wiring in close proximity with transmitter. Noise can sometimes be overcome by increasing loop resistance thereby increasing calibrator signal. Noise effects can also be reduced by connecting calibrator directly at transmitter. Generally noise is only a problem when calibrator is communicating with transmitter and does not affect normal operation of transmitter.3. Check voltage at transmitter it should be at least 12 V when 20 mA is flowing in loop.4. If wiring is correct, go to Section 6.6 to test transmitter.
Calibrator doesnot
communicatewith
transmitterYes
Yes
Check:1. If current greater than 22 mA, disconnect at sensing element and re-check. If current returns to normal, check sensing element using checkout procedure in Section 5.7. If current does not return to normal, test transmitter with procedure in Section 5.6.
2. If loop current is 0 mA, check polarity of wiring at transmitter. If OK check for open loop.
3. If loop current is between 0 and 3 mA transmitter is likely bad. Test with procedure in Section 5.6.
4. Check voltage at transmitter, it should be at least 12 volts when 20 mA is flowing in loop.
5. Disconnect the three probe cable connections at transmitter and retry. If it now communicates, check cable and probe as described in Sections 5.7 & 5.8.
1. Check Power Supply source resistance. The 250 ohms may be built in as with the Drexelbrook 401- 500 series or most DCS inputs.
2. If not, add enough resistance for loop to be at least 250 ohms.

CAUTION: Sensing element is intrinsically safe. Therefore, when using this product, it is recommended that all service activity comply with appropriate guidelines.
Remove sensing element from vessel to a safe area. Test outlined in steps 1 and 2 can be performed in a metal test vessel filled with high conductivity water. Depending on locality, tap water may not be suitable. If not, a spoonful of table salt may work.
Inthefollowingtests,ifitisnotpossibletoraiseorlowerlevel in vessel, sensing element may be suspended in ametal pipe or other container that is filled with conductive water(seeabovenote)andconnectedtogroundedsensingelement condulet.
