Seller may, at its option, cancel any accepted Order if Buyer fails to pay any invoices when due.

DELIVERY: Shipments are F.O.B place of manufacture (“Shipping Point”) and the Buyer shall pay all freight, transportation, shipping, duties, fees, handling, insurance, storage, demurrage, or similar charges from Shipping Point. Delivery of goods to common carrier shall constitute delivery and passing of title to the Buyer, and all risk of loss or damage in transit shall be borne by Buyer. Any claims or losses for damage or destruction after such delivery shall be the responsibility of Buyer.

Seller reserves the right to make delivery in installments which shall be separately invoiced and paid for when due, without regard to subsequent deliveries. Delay in delivery of any installment shall not relieve Buyer of its obligation to accept remaining deliveries.

Acknowledged shipping dates are approximate only and based on prompt receipt of all necessary information from Buyer and Buyer’s compliance with terms of payment.

TAXES: All sales, excise and similar taxes which Seller may be required to pay or collect with respect to the goods and/or services covered by any Order, shall be for the account of the Buyer except as otherwise provided by law or unless specifically stated otherwise by Seller in writing.

TERMINATION AND HOLD ORDERS: No Order may be terminated by Buyer except upon written request by Buyer and approval by Seller, and if said request is approved by Seller, under the following conditions: (1) Buyer agrees to accept delivery of all of the units completed by Seller through the workday on which Seller receives the written termination request; (2) Buyer agrees to pay to Seller all direct costs and expenses applicable to the portion of the Order that is incomplete.

WARRANTY: A. Hardware: Seller warrants its goods against defects in materials and workmanship under normal use and service for one (1) year from the date of invoice. B. Software and Firmware: Unless otherwise specified, Seller warrants for a period of one (1) year from date of invoice that standard software or firmware, when used with Seller specified hardware, shall perform in accordance with Seller’s published specifications. Seller makes no representation or warranty, expressed or implied, that the operation of the software or firmware shall be uninterrupted or error-free, or that functions contained therein shall meet or satisfy the Buyer’s intended use or requirements. C. Services: Seller warrants that services, including engineering and custom application, whether provided on a fixed cost or time and material basis, shall be performed in accordance with generally accepted industry practices. D. Remedies: Seller’s liability under this section is restricted to replacing, repairing, or issuing credit (at Seller’s option) for any returned goods and only under the following conditions: (1) Seller must be promptly notified, in writing, as soon as possible after the defects have been noted by the Buyer, but not later than (1) year from date of invoice from Seller; (2) The defective goods are to be returned to the place of manufacture, shipping charges prepaid by the Buyer; (3) Seller’s inspection shall disclose to its satisfaction that the goods were defective in materials or workmanship at the time of shipment; (4) Any warranty service (consisting of time, travel and expenses related to such services) performed other than at Seller’s factory, shall be at Buyer’s expense. E.Repaired/Reconditioned Goods: As to out-of-warranty goods which Seller has repaired or reconditioned, Seller warrants for a period of sixty (60) days from date of its invoice only new components replaced in the most recent repair/reconditioning. F. Returns and Adjustments: No goods may be returned unless authorized in advance by Seller and then only upon such conditions to which Seller may agree. Buyer must obtain an RMA (Return Material Authorization) number from Seller prior to any return shipment and such RMA number must appear on the shipping label and packing slip. Buyer shall be responsible for the returned goods until such time as Seller receives the same at its plant and for all charges for packing, inspection, shipping, transportation, or insurance associated with returned goods. In the event that credit for returned goods is granted, it shall be at the lesser of the then current prices or the original purchase price. Claims for shortage or incorrect material must be made within five (5) days after receipt of shipment.

ALL OTHER WARRANTIES, FOR ANY OF SELLER’S GOODS OR SERVICES, WHETHER ORAL, WRITTEN, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR PURPOSE ARE EXCLUDED.

INTELLECTUAL PROPERTY: Seller’s sale of goods or provision of related documentation or other materials to Buyer shall not transfer any intellectual property rights to Buyer unless Seller specifically agrees to do so in writing. Seller shall retain ownership of all applicable patents, trademarks, copyrights and other intellectual property rights. Buyer shall not use, copy or transfer any such items in violation of Seller’s intellectual property rights or applicable law, or for any purposes other than that for which the items were furnished.

Seller shall defend any lawsuit brought against the Buyer based on a claim that the design or construction of the goods sold hereunder by Seller infringe any United States or Canadian Patent, Copyright or Mask Work Registration, provided that Buyer promptly notifies Seller of such claim in writing and further provided that, at Seller’s expense, (1) Buyer gives Seller the sole right to defend or control the defense of the suit or proceeding, including settlement, and (2) Buyer provides all necessary information and assistance for that defense. In the event of a charge of infringement, Seller’s obligation under the agreement shall be fulfilled if Seller, at its option and expense, either (i) settles such claim; (ii) procures for Buyer the right to continue using such goods; (iii) replaces or modifies goods to avoid infringement; or (iv) accepts the return of any infringing goods and refunds their purchase price; or (iv) defends against such claim.

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.

There are drawbacks, however, especiallywhenthereiscoatingoftheprobe.

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.

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

cableisdisconnected,thereisa1minutedelaybeforetheDIMbeginstodisplayuponreturnofpower.

If the display becomes distorted:• Removepowerfromthesmarttransmitter,• Waitoneminute,• Reapplypowertorestartthemeter.

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)


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. If container is not metallic, then agroundwireorrodisneededtobeplacedintothewaterand referenced to sensingelement condulet ormountingdevices.
