Make sure all componentshave been removed from the packing material. Check all thecontents against the packing slip and report any discrepanciesto the factory.Before proceeding with the installation, do the following:• Inspect all components for damage. Report any damage tothe carrier within 24 hours.• Make sure the nameplate model number on the transmitteragree with the packing slip and purchase order.• Record the model and serial numbers for future referencewhen ordering parts.2.2 Electrostatic Discharge (ESD)Handling ProcedureMagnetrol’s electronic instruments are manufactured to thehighest quality standards. These instruments use electroniccomponents that may be damaged by static electricity pres-ent in most work environments.The following steps are recommended to reduce the risk ofcomponent failure due to electrostatic discharge.• Ship and store circuit boards in anti-static bags. If an anti-static bag is not available, wrap the board in aluminum foil.Do not place boards on foam packing materials.• Use a grounding wrist strap when installing and removingcircuit boards. A grounded workstation is recommended.• Handle circuit boards only by the edges. Do not touchcomponents or connector pins.• Make sure that all electrical connections are completelymade and none are partial or floating. Ground all equip-ment to a good, earth ground.

Maximum dis-tance is calculated as Tank Height + Sensor Offset(see page 17). It is measured from the Sensor ReferencePoint (bottom of NPT thread, top of BSP thread or face ofa flange).2.3.3.2 Minimum DistanceIf the liquid level is allowed onto the antenna, noise andmedia build-up drastically decrease reliable measurement.Liquid should not be allowed closer than 15 inches(380 mm) from the bottom of the antenna mountingthreads (or face of sanitary flange).58-610 Model R82 Radar TransmitterDielectric Turbulence R821.7-3.0None 26 (8.0)Light, < 0.5" 21 (6.4)Moderate, < 1.0" 14 (4.3)Heavy, > 1.0" 7 (2.1)3.0-10.0None 33 (10.1)Light, < 0.5" 26 (7.9)Moderate, < 1.0" 19 (5.8)Heavy, > 1.0" 12 (3.7)10.0-100None 40 (12)Light, < 0.5" 32 (9.8)Moderate, < 1.0" 24 (7.3)Heavy, > 1.0" 17 (5.2)MAXIMUM DISTANCE feet (meters)
1158-610 Model R82 Radar Transmitter2.3.3.3 Problematic Applications; GWR AlternativeSome application concerns can be problematic for Radar.For these, Guided Wave Radar is recommended:• Extremely low dielectric media (εr<2.0)• Very weak reflections from the liquid surface, particularlyduring turbulence, can cause poor performance.• Tanks heavily cluttered with false targets (mixers, pumps,ladders, pipes, etc.)• During times of very low liquid levels of low dielectric media,the metal tank bottom may be detected deteriorating per-formance.2-inch (50 mm) Antenna 8-inch (200 mm) Antenna13"(330 mm)7"(178 mm)15" (380 mm) Minimum(measured frombottom of threads orflange face)2-inch (50 mm)AntennaMaximum Recess (m) is 2 ×Nozzle Diameter (d)(example: 2" diameter nozzle)8-inch (200 mm)AntennaMaximumLiquid LevelMaximumLiquid Levelmd15"(380 mm)2" (50 mm)4" (100 mm)15"(380 mm)8" (200 mm)9" (225 mm)3" (75 mm)4" (100 mm)dFigure X<Caption>Figure X<Caption>
12 58-610 Model R82 Radar Transmitter• Foam can either absorb or reflect the microwave energydepending upon the depth, dielectric, density and wallthickness of the bubbles. Due to typical variations in theamount (depth) of foam, it is impossible to quantify per-formance. It may be possible to receive most, some or noneof the transmitted energy.• Extremely high liquid levels (Overflow) conditions whenliquid very near the antenna can cause erroneous readingsand measurement failure.2.4 MountingThe R82 Radar transmitter can be mounted to a vesselusing a variety of process connections. Generally, either athreaded or flanged connection is used.2.4.1 Installing the AntennaBefore installing, make sure:• Process temperature, pressure, dielectric, turbulence anddistance are within the antenna specifications for theinstallation.• End of antenna is protected from bending or breaking.• Insulating material is not placed around any part of theRadar transmitter including the antenna flange.• Antenna is being mounted in the optimal location. See fol-lowing sections: Location, Beam Angle, Obstructions andNozzles for specific information.2.4.1.1 LocationIdeally, the Radar transmitter should be mounted providingan unobstructed signal path to the liquid surface where itshould illuminate (with microwave energy) the largest,possible surface area. See Section 2.4.1.2, Beam Angle.Unavoidable obstacles will produce reflections that must beminimized during field configuration. See Section 2.6.5.1,Target Rejection. Mount in a location equal to 1⁄2the radiusof tank top. Do not mount in center of vessel nor closerthan 10" (25 cm) of tank wall.2.4.1.2 Beam AngleThe various antenna designs exhibit different beam patterns.Ideally, the beam pattern should illuminate the maximumliquid surface with a minimum striking other objects in thevessel including the tank wall. Use these drawings to deter-mine the optimum installation location.1/2Radius> 10"(25 cm)WDistance Beam SpreadFeet Meters Feet Meters10 3 1.7 0.5220 6 3.5 1.0530 9 5.2 1.5740 12 7.0 2.10
1358-610 Model R82 Radar Transmitter2.4.1.3 ObstructionsAlmost any object that falls within the beam pattern willcause reflections that may be misinterpreted as a false liquidlevel. Although Model R82 has a powerful False TargetRejection routine, all possible precautions should be takento minimize false target reflections with proper installationand orientation.2.4.1.4 NozzlesImproper installation in a nozzle creates “ringing” whichwill adversely affect measurement. Refer to Figure 9???. TwoAntenna extension lengths are offered to allow the R82transmitter to work reliably in a variety of nozzles.The Minimum Blocking Distance of 15" (380 mm) isalways measured from the bottom of the threads or face ofa flange. The related distance as measured from the end ofthe antenna varies depending on the antenna extensionchosen. See Figure ??.The narrow beam width of the 26 GHz, R82 does allowmounting so that the antenna can be recessed inside thenozzle. Optimally, the recessed dimension should neverexceed 2×the nozzle diameter. See Figure??????NOTE: If the antenna is recessed in a nozzle it is mandatory that EchoRejection is run to eliminate any possibility of false reflections.2-inch (50 mm)AntennaMaximum Recess (m) is 2 ×Nozzle Diameter (d)(example: 2" diameter nozzle)8-inch (200 mm)AntennaMaximumLiquid LevelMaximumLiquid Levelmd15"(380 mm)2" (50 mm)4" (100 mm)15"(380 mm)8" (200 mm)9" (225 mm)3" (75 mm)4" (100 mm)d
14 58-610 Model R82 Radar Transmitter2.4.1.5 Standpipes and StillwellsThe R82 can be mounted in a standpipe or stillwell butcertain considerations should be given:• Metal stillwells only: 2" (Sched 40 max.) to 4" (50–100 mm).• Diameter must be consistent throughout length; no reducers.• Stillwell length must cover complete range of measurement(i.e., liquid must be in stillwell).• Welds should be smooth.• Vents: holes <0.125" diameter, slots <0.125" width.• If an isolation valve is used, it must be a full port ball valvewith an I.D. equal to the pipe diameter.• Bridles/Bypass Installations: The launcher should be rotated90° from process connections.• Configuration must include an entry for PIPE I.D.See Section 2.6.5.1, Item 34- PIPE I.D.• There will be some increased dielectric sensitivity; systemGAIN will be reduced when PIPE ID >0.2.4.2 Installing the TransmitterInstall the Transmitter with its integral antenna by threadinginto the vessel. DO NOT OVERTIGHTHEN as this maycause damage to the plastic threads.• Do not place insulating material around any part of theradar transmitter including the antenna flange.• Installation for NEMA 6P/IP 68- the transmitter can beinstalled to allow for temporary submergence to 6 feet (1.8m):- use TFE paste to seal conduit entries and antenna processconnection- Do not overtighten housing cover; O-ring developswater-tight seal without excessive tightening2.4.2.1 OrientationThe R82 transmitter utilizes a linearly polarized, microwavebeam that can be rotated to improve its performance. Properorientation can minimize unwanted target reflections, decreasesidewall reflections (multipath) and maximize direct reflec-tions from the liquid surface.The internal launcher mechanism can be turned to optimizeperformance. The launcher has index marks numbered1–18 (representing 10–180 degrees). The Polarizationpattern is at 45 degrees to the transmitter display whenthe mechanism is at the #9 position.Figure XBeam Orientation with #9Launcher PositionFigure XR82 Mounted in Stillwell (Bridle)GroundLauncher Adjustment(with #9 Position Selected)45°(+)(-)45°Figure XPolarization Pattern
1558-610 Model R82 Radar Transmitter2.4.2.2 Initial InstallationIdeally, the transmitter should be mounted half the radiusfrom the tank wall. In a typical vertical tank, the Launchershould be adjusted so the polarization pattern is 45 degreesto the closest tank sidewall. See Figures ? & ?.For horizontal cylindrical vessels, aim beam down the longaxis of the vessel. Do not optimize the Quality (signalstrength) at one level in the vessel.A transmitter mounted within 10" (25 cm) of a tank wallmay demand orientation adjustments to limit multipathand optimize performance. See Section 2.4.2.3, Poor EchoStrength.2.4.2.3 Poor Echo StrengthPoor signal quality has many potential causes. Following aretwo initial areas for investigation.Launcher Orientation: Initial launcher orientation is always45 degrees (see Sections 2.4.1 & 2.4.2). In tall vessels andwhen antenna is mounted close to the tank wall, improve-ment in signal quality may be attained by rotating thelauncher to 90 degrees.Signal Loss: If the Level signal is lost repeatedly at a specificpoint in the vessel, it is usually a symptom that multipath(side-wall reflections) are causing cancellation by returningto the transmitter exactly 180° out of phase with the Levelsignal. Utilize the following procedure:• Go to transmitter screen #5 which shows both Level andEcho Strength.• Bring the Level up (or down) to the exact point where thesignal is repeatedly lost. Monitor the Echo Strength thispoint is being approached. The Echo Strength will degradeto a low point before it begins to increase.• At the poorest Echo Strength slowly rotate the launcher1–2 notches. Allow the unit to stabilize for approximatelyone minute. Repeat this process until the Echo Strength isoptimized.1/2 RadiusOrientationMechanismin #9position45°90°Figure XTop ViewMounted 1⁄2radiusFigure XxxxxGroundLauncherAdjustment(+)(-)
16 58-610 Model R82 Radar Transmitter2.5 WiringCaution The R82 Radar transmitter operates at voltages of 16–36VDC (GP) and 16-28.6 VDC (IS). Higher voltage will dam-age the transmitter.Wiring between the power supply and the Radar transmittershould be made using 18–22 AWG shielded twisted pairinstrument cable. Within the transmitter enclosure, con-nections are made to the terminal strip and the groundconnections. Trim excess wiring to minimize clutter, noiseissues and allow access to Launcher adjustment (seeFigure ??). The directions for wiring the Radar transmitterdepend on the application:• General Purpose or Non-incendive (Cl I, Div. 2)• Intrinsically SafeNOTE: For ATEX installation guidelines refer to bulletin BE 58-610.2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)A general purpose installation does not have flammablemedia present. Areas rated non-incendive (Cl I, Div. 2) haveflammable media present only under abnormal conditions.No special electrical connections are required. If flammablemedia is contained in the vessel, the transmitter must beinstalled per Cl I, Div. 1 standards of area classification.To install General Purpose or Non-incendive wiring:1. Remove the cover to the wiring compartment of the trans-mitter. Install the conduit plug in the unused opening.2. Install a conduit fitting and pull the supply wires.3. Connect shield to an earth ground at power supply andleave floating at the transmitter.4. Connect an earth ground wire to the nearest green groundscrew per local electrical code (not shown in illustration).5. Connect the positive supply wire to the (+) terminal andthe negative supply wire to the (-) terminal.6. Replace cover to the wiring compartment of transmitter.GroundLauncherAdjustment(+)(-)Figure Xxxxx

Then, power-up the transmitteron the bench and follow through the step-by-step proce-dures for the menu-driven transmitter display. Informationon configuring the transmitter using a HART communica-tor is given in Configuration Using HART (Section 2.7).2.6.1 Operating ParametersSome key information is needed to configure the Radartransmitter. If necessary, complete the configuration infor-mation table in Section 1.1.2.2.6.2 Setting Up for Shop ConfigurationThe Radar transmitter can be configured at a test bench byconnecting a 24 VDC power supply directly to the trans-mitter terminals. The connections are illustrated in theaccompanying diagrams. An optional digital multimeter isshown if current measurements are desired.When using a HART communicator for configuration, aminimum 250 Ωline load resistance is required. See theHART communicator manual for more information.2.6.3 Transmitter Display and KeypadThe R82 transmitter has a local user interface consisting ofa 2-line by 16-character liquid-crystal display (LCD) and4-push-button keypad. All transmitter measurement dataand configuration information is shown in the LCD.The transmitter default display is the measurement screen.It cycles every 5 seconds to display *STATUS*, *LEVEL*,*ECHO STRENGTH*, *%OUTPUT*, *LOOP CUR-RENT* and *LOCAL TAG* information. The transmit-ter defaults to this display after 5 minutes if no keystrokesare sensed. You can also access each of these screens indi-vidually. The display will not return to the default screenif left in one of these screens. For example, the device canbe left to read only LEVEL indefinitely if left in thisscreen.GroundLauncherAdjustment(+)(-)Figure Xxxxx

20 58-610 Model R82 Radar Transmitter2.6.5 Password Protection (Default = 0)The Radar transmitter is password protected to restrictaccess to certain portions of the menu structure that affectthe operation of the system. When the proper password isentered, an exclamation point (!) appears as the last charac-ter of the first line of the display. The password can bechanged to any numerical value up to 255. The passwordis required whenever configuration values are changed.The default password installed in the transmitter at the fac-tory is 0 (password disabled). The last step in the configura-tion menu provides the option to enter a new password. If0 is entered as a password, the transmitter is no longer pass-word protected and any value in the menu can be altered(except diagnostic values) without entering a confirmingpassword.NOTE: If the password is not known, the menu item New Password(Section 2.6.6.1, item #39) displays an encrypted value repre-senting the present password. Call the factory with thisencrypted value to determine the actual password.

2958-610 Model R82 Radar Transmitter3.0 Reference InformationThis section presents an overview of the operation of theModel R82 Radar Level Transmitter, information on trou-bleshooting, common problems, listings of agencyapprovals, lists of replacement and recommended spareparts, and detailed physical, functional and performancespecifications.3.1 DescriptionThe Model R82 is a two-wire, 24 VDC level transmitterbased on the concept of pulse burst radar operating at26GHz. The electronics are mounted in a metal or plastichousing with an innovative, internal launcher orientationmechanism.3.2 Theory of Operation3.2.1 Pulse Burst RadarThe Model R82 is a top-mounted, downward-looking pulseburst radar operating at 26 GHz. Unlike true pulse devicesthat transmit a single, sharp (fast rise-time) waveform ofwide-band energy, the R82 emits short bursts of 5.8 or26GHz energy and measures the transit time of the signalreflected off the liquid surface. Distance is calculated utiliz-ing the equation Distance = C ×Transit time/2, then devel-oping the Level value by factoring in Tank Height andSensor Offset information. The exact reference point fordistance and level calculations is the Sensor ReferencePoint—bottom of an NPT thread, top of a BSP thread orface of a flange.Distance = c ´(time ¸2)1 ns500 nsNPTProcessConnectionBSPProcessConnectionSanitarySensor Reference PointPulsePulse Burst
30 58-610 Model R82 Radar TransmitterThe exact level measurement is extracted from false echoreflections and other background noise via the use of sophis-ticated signal processing. The new R82 circuitry is extreme-ly energy efficient so no duty cycling is necessary to accom-plish effective measurement. For this reason, the R82 cantrack high rates of change that were heretofore impossiblewith existing loop-powered radar transmitters.3.2.2 Equivalent Time SamplingETS, or Equivalent Time Sampling, is used to measure thehigh speed, low power EM (electromagnetic) energy. ETS isa critical key in the application of Radar to vessel levelmeasurement technology. The high speed electromagneticenergy (1000 ft/µs) is difficult to measure over short dis-tances and at the resolution required in the process industry.ETS captures the EM signals in real time (nanoseconds) andreconstructs them in equivalent time (milliseconds), whichis much easier to measure with today’s technology.ETS is accomplished by scanning the tank to collect thou-sands of samples. The round-trip event on a 40-foot (12.3m)tank takes only 82 nanoseconds in real time. After it isreconstructed in equivalent time it measures 123 milliseconds.TankHeightSensor Offset + Tank Height =Distance from processconnection to tank bottom20 mA4 mASensor Reference PointSensor Offset (+)BlockingDistanceDistanceSafe ZoneMediaLevelLevel OffsetLowestMeasurableValue
3158-610 Model R82 Radar Transmitter3.3 TroubleshootingThe Model R82 transmitter is designed and engineered fortrouble-free operation over a wide range of operatingconditions. Common transmitter problems are discussedin terms of their symptoms and recommended correctiveactions.WARNING! Explosion hazard. Do not remove covers unless powerhas been switched off or the area is known to be non-hazardous.Use of the included PACTware™PC program is highlyrecommended and invaluable for troubleshooting andadvanced calibration. A HART RS232 or USB modem(purchased separately) is required.
