1This includes the ability to have a simple or complex user interface, a remote user interface, or even no user interface.2Basic ConceptsCommunicationsThe Ronan X96S Level gage provides both 4-20 mA current loop and HART communications.4-20 MAFor many years, the field communication standard for process automation equipment has been a 4-20 mA current loop signal. Thecurrent varies in proportion to the process variable being represented. In typical applications, a signal of 4mA will correspond tothe lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%) of the calibrated range. Thus, ifthe system is calibrated for 1 to 3 feet, then an analog current of 12mA (50% of range) will correspond to a level of 2 feet.HARTHART Field Communications Protocol extends the 4-20mA current loop standard to enhance communication with smart fieldinstruments. The HART protocol was designed specifically for use with intelligent measurement and control instruments whichtraditionally communicate using 4-20mA analog signals. HART preserves the 4-20mA signal and enables two-way digitalcommunications to occur without disturbing the integrity of the 4-20mA signal. Unlike other digital communication technologies,the HART protocol maintains compatibility with existing 4-20mA systems, and in doing so, provides users with a backwardcompatible solution. HART Communication Protocol is well established as the "de facto" industry standard for digitally enhanced4-20mA field communication.The enhanced communications capability of intelligent field instruments employing the HART protocol, offers significantlygreater functionality and improved performance over traditional 4-20mA analog devices. The HART protocol permits the processvariable to continue to be transmitted by the 4-20mA analog signal and additional information pertaining to other variable,parameters, device configuration, calibration, and device diagnostics to be transmitted digitally at the same time. Thus, a wealthof additional information related to plant operation is available to central control or monitoring systems through HARTcommunications.VariablesThere are two types of variables, communications variables and device variables.Communication VariablesHART defines four device variables, PV (Primary Variable), SV (Secondary Variable), TV (Tertiary), and QV (Quaternary). PVis assigned to the primary 4-20 ma loop . HART is also communicated over this loop. SV is assigned to an optional secondary 4-20 ma loop.Device VariablesThe Ronan X96S Level gage has 2 device variables:Device Variable ValueLevel LevelHead Temp Head Temperature3Configuration VariablesThe Ronan X96S Level gage has many configuration variables that are accessed through its menus.4TheoryTheory of Radiation GagingRadiation gages operate on the principle of radiation absorption and transmission.A beam of gamma radiation is directed from the source holder, through the vessel and its process material, and onto the surface ofthe detector.Radiation which is not absorbed by the material through which it passes, is transmitted to the surface of the detector.Process measurement is possible because the amount of radiation absorbed and transmitted is predictable.The absorbed radiation is directly related to the level of process material in the vessel while the transmitted radiation is inverselyrelated to the level of process material in the vessel.Therefore, an increased process level results in a decrease of transmitted radiation.Since the radiation that's not being absorbed is being transmitted, the process level can be inferred by measuring the amount ofradiation reaching the detector at any point in time.The detector's output signal, in counts, also varies inversely to the processlevel.When the process level is low the detector is exposed to a maximum amount of radiation which produces a HIGH output ofcounts. When the process level is high the process material "shields" the detector and prevents radiation from reaching thedetector, producing a LOW output of counts.The X96S Microprocessorconverts the detector signalto user's measurement units oflevel: m, mm, cm, in, ft.The X96S displays the output measurement range in the selected user units.The "zero" of the measurement range represents thelowest level of interest, while the "span" of the measurement range represents the highest level of interest.Reduction of the signal "noise" due to radiation statistics is handled in the stage of signal processing known as digital filtering.Digital filtering is a form of statistical averaging used to smooth, or dampen,random radiation as well asprocess-related noise.Increasing the digital filters time constant decreases signal noise.Dynamic tracking permits the gage response to temporarily by-pass the digital filter.This is helpful in some processes wheresudden or drastic step changes in process must be observed in their true, or unfiltered, state.Software also compensates for the decay of the radioactive source activity.On-going adjustments are made automatically for therate of decay, or source half-life.Principles of OperationThe detector's raw output signal is processed through several stages of software in the X96S.Some of the more significant stages of signal processing are:Units Conversion conversion of counts into user-selected level unitsMeasurement Range 4-20 mA output defined by the user-selected range in user-selected units.Digital Filtering signal smoothing to reduce statistical radiation noiseDynamic Tracking quick gage response to quick process changes.Source Decay Compensation automatic compensation for the radioisotope decay5Calibration (Referencing) calibration of gage to user process.The Calibration (or Referencing) procedurerelates detector output (in counts) to numeric values that accurately represent theactual process level.The level algorithm used by the X96S software is a simple transfer function.That is, the relationship between the detector outputand the process level is mathematically expressed as:( )+ =0000L LI II IL LevelffWhere:

If = detector signal with calibrate (full) level (Lf) in vessel

Io = detector signal with reference (low) level (L0) in vessel I = current detector signal L0 = level @ reference (low level) Lf = level @ calibration (high level)6PasswordNotice:To access the Programming Menu, the Password is 101010.Step 1: Power Up You should now be on the Status Screen.Step 2: Press F3 to go back.Step 3: Now enter the password.

The top line of the display isreserved for the analog bar, if enabled. The next line is used forthe Ronan logo. Line #3 shows the device model line. Line #4displays the specific screen title. That title is typically a screendescription or required action. The remainder of the lines, with theexception of the last line, are screen or action dependent. The lastline displays the active function keys labels.Directly beneath the display is a keypad. The keypad is dividedinto two parts:a 4 key function key section anda 6 key (2 rows of 3 keys) cursor control sectionNavigating MenusThe menu and the display screen are one or more lines, each consisting of a line label (name of the entry) and optionalvalue and units. In most cases the menu navigation is exactly following the Rosemount 275 Configurators userinterface.The first column is reserved for direction keys if the number of lines does not fit the physical display. The secondcolumn will show a right arrow character when the cursor is on this line and there is sub-menu or some other screen oraction assigned to this line. If the menu is not at the top level, the end of the menu title line will show left arrow toindicate it, and to remind that the user could go back to the previous menu by pressing left arrow.If the line length is longer than the physical display, a right arrow will be displayed, and if the right arrow key ispressed, the value will be displayed in a screen, similar to the editing one, but with editing disabled.Depending on the type of the function assigned to the line a different screen will be shown when the user presses theright arrow key.If this line is a sub-menu, another menu opens.CF1 F2 F3 F4 X96S 30%Ronan EngineeringX96S Level GageMenu TitleMenu line 1Menu line 2Menu line 3 Menu line 4Menu line 5.Menu line 11Func1Func2Func3Func425Editing ValuesThe editing of different types of values is designed around the use of the four direction keys and up to 4 function keys. The leftand right arrow keys are used to position the cursor to the letter/digit to be edited, and up and down arrow keys are used to scrollbetween the possible values for this position.In all editing functions, the edited value is displayed below the current value.Editing Fixed Point NumbersUsing left and right arrow keys, position the cursor at the desired position and scroll the digit at this position using up and downarrow keys.

The up and down arrow keys are used to select thedesired choice, and F4 is used to confirm it. F3 is used to abort the editing and leave the value unchanged.X96 Local Display Vs 275 CalibratorThe local display user interface is very similar to the 275 Calibrator, but there are some differences. One of the major ones is thefact that the X96 local display lacks a numeric keypad. This automatically means that the shortcuts are not supported, as also thevalue editing is done using only the cursor keys.Another difference is the fact that all values in the local display are immediately updated, and there is no need to use SEND actionwhenever a value is changed. Also, the flashing heart character indicating that the configurator is exchanging data throughHART communication is not needed and thus not presented on the local display.When there is a value to be displayed and the line length doesnt fit the display, the 275 Configurator displays the label only andlets the user see the value using the right arrow key. X96 local display will display whatever could fit the display, thus indicatingto the user that there is more to be displayed and the right arrow sign is not indicating a new menu.26InstallationCautionSpecific LicenseGeneral LicenseUnpackingStorageRonan'sMonitor Systems use a sealed radioactivecesium(Cs-137) source which is safe if handled properly.MostLevel Monitors are mounted to large vessels.Installations on vessels that permit personnel access requirea specific license.Your company's specific license willname a Radiation Safety Officer (RSO) or RadiationProtection Officer (RPO).The RSO for your companymust be notified immediately uponreceipt of the gage.

It instructs the microprocessor to read and store the detectorcounts for a low and high level ofprocess. Once the system isconditioned to recognize the low and high level, it willprovide a4-20 mA output over the entire range of interest.Reference ModesOne ofyour first tasks will be to calibrate the system.The first step in the calibration procedure is to "reference" the gage onsome known level.The steps involved in the referencing procedure will vary slightly depending upon the mode selected as theconstant.One of these three REFERENCE MODES will be active on your system:Referencing EMPTY (Level = 0)Referencing with PROCESS at known levelReferencing with ABSORBERCalibrationLow ReferenceDepending on the Reference Mode selected, you must set up the radiation path in the vessel to the Reference condition (vessel isEMPTY, PROCESS is at a known low level, or the proper ABSORBER is in place).If ABSORBER or PROCESS is selected,you will need to supply the actual level represented.If you selected EMPTY, the system will automatically supply a level valueof 0 for you.High CalibrationAgain, depending on the Reference Mode selected, you must set up the radiation path in the vessel to the Calibration condition.You will also need to supply the actual level being set up.Preparation for CalibrationDocumentationFor future reference, document these items:(a)Environmental/process conditionsthat influence the reference/ calibration. The next time a calibration is performed, you willneed to duplicate the conditions, or account for the differences.(b) All changes made to factory-default settings such as time constant, reference constants, gain, etc.(c)The information from the status displays.A record of "counts" being received from the detector may assist with futuretroubleshooting efforts.35ConfigurationRonan ships the Level Monitor System with factory-default software settings.Those settings are responsible for the informationthat initially appears on the status displays.After installation at your site, you may need to reconfigure the system to fit your application. The goal is to correlate the X96Soutput with your actual level readings. The list below summarizes the activities that are detailed in the remainder of this chapter:-Check the factory-default settings to be sure they are appropriate for your circumstances.IF NOT, make the necessarychanges and document those changes for future reference.-Perform an initial calibration to correlate the X96Ss output to the actual process level-Document detector output counts at calibrated values to assist in troubleshooting. Also, record changes you make to factory-default settings.Keep this information for future reference.36DetectorScintillator DetectorDescription The Ronan scintillation detector consists of three main components: Theplastic scintillation n crystal, the photomultiplier tube (PMT), and theassociated electronics.Scintillation Crystal The crystal used for the Continuous Level Monitor System is poly vinyltoluene (PVT) plastic.The crystal produces light pulses which areproportional to the incident radiation events striking it.Typically mounted in a stainless steel shell the entire crystal assembly issealed against moisture and dirt and is non-repairable.An integral flangeserves to mount the crystal to the PMT.A special silicone membraneserves as an optical coupling medium between the crystal and the PMT.Photomultiplier Tube The PMT is a light sensitive vacuum tube with a photosensitive layer thatconverts the light pulses to an electrical current.Light pulses from thecrystal strike the photosensitive layer and release electrons.A high voltagepower supply connected to the photosensitive layer accelerates theelectrons through stages of current amplification.The PMT and its associated components are housed in a special magneticshield.The tube is shock-mounted internally, with an interface plate at thetop, which also mounts the electronics and the outer shell.____________________________________________Electronics Four boards, housed in a stainless steel shell, comprise the electronics andtheir functions. High Voltage Power Supply Preamplifier Discriminator Pulse Output37Detector Service The critical components of the electronic circuit and thePMT/Crystal Assembly are aligned before leaving thefactory.If any component of the Scintillation Detector isadjusted or replaced, the performance of the entire systemwill be adversely affected and will require realignmentbefore continued use is possible.Therefore, the scintillation detector IS NOT fieldserviceable.Should a problem arise with the detector, theentire Detector Assembly should be returned to Ronan forrepair/replacement.38ION ChamberDetector/Amplifier Ronans ion chamber detector is filled with an inertAssembly high-pressure gas.It uses low-voltage (-15VDC) biasand generates a low-level current proportional to the gammaradiation incident on the detector.The current(DET-7471-XXX) generated is on the order of 10 A, so an electrometer amplifier isrequired to convert the current to a low-impedance, high levelvoltage signal.The signal is then measured by the X96SMicroprocessor, which converts the voltage signal to a level (ordensity) output of4-20mA for a specified measuring range.Refer to drawing B-6409-K.The current (I), generatedCircuit Descriptionby the ion chamber, is fed into the inverting inputterminal of the electrometer amplifieer, (IC1).The electrometeramplifier output is filtered by R2C4(a microphonic, low-passfilter) and fed into a follower amplifier.The output of IC2 isproportionally fed back to the inverting terminal to provide aclosed-loop gain based on the value of the gain resistancepotentionmeter (R2) on the X96S input board. (B-9742-K).The detectors gain is adjusted whenever the signal output of thedetector is too high and may saturate the input of the X96S, whichis approximately 3.5VDC. The output must be less than 3.0VDCwith an empty vessel.An offset zero control (R6), used to null the offset voltage of theelectrometer amplifier, is factory adjusted and glyptal coated. R6is adjusted to make the output, (TP1), zero with Rf shorted. (TP2is circuit common.)The most important components of the amplifier are theoperational amplifier (IC1), feedback resistor (Rf), and feedbackcapacitor (Cf).If these components are substituted, theperformance of the system will be adversely affected.Reference:B-6409-KB-9742-K39Servicing the Detector The ion-chamber detector contains pressurized inert gas.The ionchamber itself is not serviceable and must be returned to thefactory for service.Instructions follow for DetectorRemoval/Replacement.However, a qualified technician can troubleshoot and service thedetectors amplifier assembly.Instructions follow for thatprocedure as well.Some precautions are needed when handlingthe detector/amplifier assembly.It is important to keep the interior of the detector/amplifier dry.Moisture on the high-impedance components will cause leakagecurrents.If the amplifier lid is opened, it is important to see thatwarm, dry air is introduced into the amplifier before replacingthe gasket lid.40Detector Removal/ReplacementELONGATED DETECTORS NOTES:To avoid damage in shipment or installation, theelongated detectors are packaged separate from thehousing.Avoid subjecting detectors to mechanicalshock.Avoid supporting detector by its chain handle,or other lifting devices, for prolonged periods of time.When detector is properly seated on the bottom of thehousing, the hold-down clamp tab will engage andthe extension rod screw can be adjusted to tightendetector assembly into housing.DETECTOR HOUSING/BRACKET ASSEMBLY NOTES:Many detectors are shipped inside the housing/bracketassembly.Bolts at the top and bottom of the C-Clampare used to adjust the assembly around a pipe.1)Check NOTES below for illustrationsand cautions that apply to your specificequipment.2)Unscrew cap on detector housing.3)Unscrew connector on top of detector.4)Remove detector from housing.5)Carefully install replacement detector inhousing.6)Screw connector back onto detector.7)Immediately replace detector-housingDetector HousingCapDetector HousingCable ConnectorDetector41Removing the DetectorAmplifier Circuit Board(CBAY-6102)Follow this procedure to remove the electrometer amplifier circuitboard:1.Remove the amplifier cover by unscrewing the hex socket headcap screws.2.Remove the MS connectorfrom the amplifier cover.3.Remove the two 6-32binding head screws, whichsecure the amplifier board tothe detector.4.Using a low power (60W)iron unsolder the detectorleads to the printed circuitboard standoffs.CAUTION: Excessive twistingor bending can damage thedetector leads.CAUTION: DO NOT over heatthe detector leads.
