DR4500A Truline®HTST, STLR, and Pasteurization FlowCircular Chart RecordersDR45AH - HTST (High Temperature Short Time)DR45AS - STLR (Safety Thermal Limit Recorder)DR45AP - Pasteurization (Flow)Function44-45-03-168/02Page 1 of 12SpecificationHoneywell’s Truline recorder is a one tofour-channel, microprocessor-based,circular chart recorder. Its “one-pen” stylusprinthead produces up to four analogtraces and prints alphanumeric chart dataon a blank heat-sensitive chart. All fourtraces share the same time line reference,which the Truline prints. This eliminatesthe error caused by pen alignment offsetsin conventional pen designs.Since the Truline prints the chart andgenerates the analog traces at the sametime, there is no error due to variationsin chart size caused by changes intemperature and humidity.With microprocessor electronics andsingle printhead, the TrulineHTST/Pasteurization recorder is easilyconfigured by users to meet a variety ofapplication requirements for foodprocessing.The HTST/Pasteurization models aredesigned to meet the requirements ofthe U.S. Department of Health andHuman Service’s Grade A, PasteurizedMilk ordinance.FeaturesDual Displays — Bright, vacuumfluorescent, alphanumeric digitaldisplays make pasteurization processdata instantly available to youroperation.Bargraph Display — indicatesdeviation of ± 10% of input span withcenter bar, On-control indication.User Configurable — English languageprompts, coupled with simple keystrokesequences, make configuring therecorder easy and straightforward. Youcan set and/or alter operatingparameters to fit your requirementswithout re-calibration.Four Channel Input — Up to fourchannels that monitor process variablesfrom a variety of sensor types helpreduce panel space requirements.ALMCHNRSPOUT22F175.8SP 164.8A%22658Figure 1—DR4500A Truline Recorder - HTST/STLR/Flow ModelsAll-Purpose Chart — One allpurpose,blank chart eliminates theneed for ordering and stockingseveral types of charts. You candesign the chart to match theirspecific application.“One-pen” Stylus Print Head —prints configurable alphanumericchart data including time and trendlines. This automaticallycompensates for chart widthvariations caused by changes in theambient relative humidity.Analog Inputs — Two inputs forrecording and control on the HTSTmodel. One input for control onSTLR. Third and fourth inputs availableas options. One to four inputsare available for the pasteurizationflow model.Accutune II — This standardfeature provides a new, truly plugand play tuning algorithm, which will,at the touch of a button or through adigital input, accurately identify andtune any process including thosewith deadtime andintegrating processes. This speeds upand simplifies start-up plus allows retuningat any setpoint.Fuzzy Logic — This standard featureuses fuzzy logic to suppress processvariable overshoot due to SP changesor externally induced processdisturbances. It operatesindependently from AccutuneIItuning. It does not change the PIDconstants, but temporarily modifiesthe internal controller response tosuppress overshoot. This allows moreaggressive tuning to co-exist withsmooth PV response. It can beenabled or disabled depending on theapplication or the control criteria.Time/Date — To guard againstunauthorized chart advancement, anintegral real-time clock providesaccurate timing for the recorder’s timeand date printing, and also anyoperator changes.

This means thatits software now primarily determinesthe recorder's capabilities.Since Honeywell has preprogrammeda variety of functional capabilities intothe recorder, you only have toconfigure those functions that arespecific for the given application. Youconfigure the recorder by followingEnglish language prompts that appearin the digital displays.The configuration data (type of input,chart speed, chart range, alarmsettings, tuning constants, etc.) arestored in nonvolatile memory for safekeeping in the event of a powerfailure.Operator InterfaceTwo digital displays (Figure 2) presentthe process variable (PV) value and bykey selection, the controller set point;controller output; deviation fromreference input; or engineering unitsas desired. The lower display can beset to scroll or hold.20951When the optional inputs formeasuring the temperature at thedivert valve is active, the lower displayindicates the temperature beingmeasured at the divert valve as thedefault value. In configuration mode,digital displays are pre-empted byEnglish language prompts and valuesthat you use to enter configurationdata.Indicators light to show alarmconditions, which channel PV is ondisplay, use of remote set point,which output relay is on, selectedtemperature unit, and controller’smode of operation.A deviation bargraph lets operators tellat a glance if the process variable isat, above, or below the controller’ssetpoint. The keypad through whichconfiguration data is entered alsoserves as an integralautomatic/manual station that providesbumpless transfer for controllers.Recording and PrintingBoth the chart and the printhead aredriven by the stepper motors, whichare controlled by the microprocessorallowing precise maintenance freeoperation.Since chart speed is configurable, youcan easily alter the chart speedthrough the keypad. Gear changing oradditional motors are no longerrequired.The microprocessor uses the configuredchart range data as well as theinput data to determine the properprinthead position. The stepper motoraccurately positions the printheaddrive.

44-45-03-16Page 3Recording and Printing,continuedBy using a “one-pen” printhead that iscapable of printing alphanumericcharacters, you can now set various“printed” chart data through configuration.This means that such chartdata as range marking in engineeringunits, digital values for processvariables, and trace identification areeasily personalized for the application.This data, plus printed time lines andengineering units of scale eliminatethe need to maintain an inventory of avariety of preprinted charts.The Truline recorder uses a dot filltechnique from a microprocessoralgorithm to produce a continuousanalog trace of a process variable.Digital ControllerThe DR4500A Series recordercontroller includes an integralmicroprocessor-based, one or twoloop, PID controller. The recordercontroller produces a 4–20mA outputfor controlling the Hot Water loop orFlow and on-off relay output for thedivert valve.As with the record functions, Englishlanguage prompts quickly guide youthrough the entry of all the controller’sconfigurable parameters.A second optional control output isavailable to control system backpressure on the DR45AP version.In addition to this, a high pressure limitoutput can be set.DiagnosticsAll DR4500A Series recorders includeself-diagnostic systems that checkcritical operations and provide errormessages to alert you about detectedfaults.Power-up self-diagnostics is amicroprocessor controlled diagnosticprogram that runs tests on selectedcircuitry when the recorder is poweredup. A “key” test allows you to initiate,on demand, a self-diagnostic routinethat checks the keypad and frontpanel displays.Process InterfacePower, input, and output wiringconnect to terminations inside thecase. Knockouts in the sides andbottom of the case accept conduitconnections for convenient wire entry.ConstructionThe DR4500A Series recorder ishoused in a molded case, which canbe panel or surface mounted.Circuitry is partitioned on printedcircuit boards for ease of service.A UL and FM approved NEMA4X dooris also available.Input ProcessingThe recorder requires a 3-A approvedsanitary high-speed RTD sensor(Such as RDF Model 21345-6-E-T11/2-2) to measure hot milktemperature. Various types of sanitaryfittings and sizes available with thishighly responsive, reduced tip sensorwill meet your specific applicationrequirements.For DR45AH/AS recorders using theoptional Digital ReferenceMeasurement, a 3-A approved sanitaryhigh-speed, dual element RTDsensor (Such as RDF Model#21345(SP)-6-E-T11/2-2) orequivalent is required to measure theHot Milk Temperature and the DigitalReference Temperature.Each input is sampled at a rate of 3times per second for 1 or 2 inputs, or 3times in 2 seconds for 3 or 4 inputs.Each sample is amplified and thenconverted to a digital signal which isisolated and passed to themicroprocessor. A digital filter withconfigurable time constants lets youapply input signal smoothing asdesired. All non-linear inputs arelinearized by the microprocessor.In the unlikely event of failure, you caneasily and quickly replace theresistance bulb temperature sensor.Compliance to MilkOrdinance RegulationsDR45AH/AS/AP fully complies with thestrict regulations of the “Grade APasteurized Milk Ordinance”.Compliance features include:• Internal configuration switchThis security switch limits access toconfiguration parameters.In the switch “off” position, you canconfigure all the recorder/controllerparameters to the desired value.The “on” position locks the majorityof the configurable parameters,including hot milk diversionsetpoint, so that they may not bechanged.The only functions remaining in the“on” (locked) position are:Chart - start the chart or place it inhold.Man/Auto - You can place the hotwater temperature controller (whichcontrols the Milk temperatureindirectly) in Manual or Automaticmode as defined below:MAN - The output signal to thehot water valve is manuallycontrolled.AUTO - The setpoint for the hotwater controller is adjustable.Lowr/Disp - Lets you scroll throughthe process variable inputs,outputs, setpoints and deviationfrom setpoint.Configuration - allows changes toControl 1 and Control 2 tuningparameters plus adjustments totime/date/day/year.• Diversion Valve PositionIndicationRed and Green lights, visiblethrough the door, indicate flowdiversion valve position.Red indicates flow diversion,Green indicates forward flow.• Electronics Access ControlChart Plate sealing provisions,using a wire lead seal, preventaccess to the electronics and theinternal configuration switch.

44-45-03-16Page 4Model DR45AHRecorder/ControllerOn the DR45AH recorder, the divertvalve temperature is printed on thechart when Input 1 is programmed asa Digital Reference TemperatureIndicator.When a diversion occurs, the DR45AHrecorder/controller will automaticallyprint on the chart the temperaturemeasured at the divert valve by theDigital Reference Thermometer andthen, when forward flow is startedagain after the diversion, it will printthe temperature again.In addition, there are red and greenindicator lights on the front of therecorder that provide a visualindication of forward flow or flowdiversion.Milk Pasteurization ProcessFigure 3 is a flow diagram of the HTSTmilk pasteurization process. Milk flowsfrom the raw milk supply tank throughthe plate-type heat exchanger, whereit is heated to pasteurizationtemperature prior to entering theholding tube.The tube size ensures that the milkremains at the pasteurizationtemperature for the required time.Hot milk temperature is measured as itleaves the holding tube. If thistemperature is above the pasteurizationtemperature, the DR45AHHTST allows milk flow to proceed topackaging or storage. If the milk isbelow pasteurization temperature, theDR45AH HTST diverts it to the rawmilk tank for reprocessing.For this application, DR45AH HTSTuses two analog inputs, one digitalinput, one 3-mode controller and oneon-off controller to control:• hot water flow to the plate heatexchanger• Flow diversion valve position.Pasteurization temperature controlconsists of recording the informationshown on the circular chart (Figure 4)and implementing the followingstrategies:Model DR45AHRecorder/Controller, continuedMilk Pasteurization Process , cont.1. The first analog input is hot watertemperature (if Digital ReferenceTemperature option is selected,then Input 3 is the Hot WaterTemperature) , which indirectlycontrols milk temperature in theplate heat exchanger. Thistemperature may be recorded.2. The hot milk temperature is thesecond analog input. Thistemperature is recorded.The high-precision RTD sensorprovides this temperaturemeasurement. DR45AH HTSTuses 100-ohm ( α = 0.00385 )platinum bulb actuation to providehot milk temperaturemeasurement accuracy of ±0.3°F3. A switch on the flow diversionvalve provides the digital input toactivate the frequency pen thatrecords the valve position on theouter portion of the chart. The usersupplies and installs the two relaysthat connect therecorder/controller to thepasteurizer system wiring.You can also record the flow diversiontemperature setpoint without anadditional analog input.Model DR45ASSafety Thermal Limit RecorderThe DR45AS (STLR) model providesall the same features of the DR45AHHTST recorder without the integral hotwater control loop.The DR45AS model is set up to recordthe hot milk temperature as well as theflow diversion valve position and toindicate this position using red andgreen lights on the front of therecorder.Optionally, it can also be set up withthe integral Digital Reference feature.Model DR45APRecorder/ControllerThe DR45AP Pasteurization Flowrecorder/controller can be set up tocontrol the flow rate in a pasteurizationprocess.In addition to the normal divert valvecontrol provided by high and low flowlimit setpoints, optional inputs can beset up to display and record the Rawand Pasteurized pressures in thesystem.The recorder/controller will display, inthe lower display, the system high andlow pressures from independentpressure transmitters and control thesystem back pressure using thesecond control output from therecorder/controller.In addition, a high-pressure limitoutput can be set.Optional red and green lights areavailable on the front of the recorderthat provide a visual indication offorward flow or flow diversion.Milk Pasteurization ProcessThe DR45AP controls the flow rate ina pasteurization process (Figure 3).The flow is controlled from the flowinput from a pressure transmitter orMagnetic flowmeter in the constantflow line.The recorder uses PID control and a4-20mA output to control a variablespeed pump, which adjusts the flow inthe system.The differential pressure function usespressure inputs from Input 2 and Input3 to measure and display the high andlow system pressures (Input 2 – Input3) and uses this value and the optionalsecond 4-20 mA control output tocontrol the system back pressure.Diverts are based on High Flow orLow Flow setpoints configured in therecorder/controller. Diversion to theRaw milk tank occurs when the flowrate is below the Low Flow setpoint orabove the High flow setpoint.There is a Time Delay that can beconfigured to occur before forwardflow will begin. The configurable rangefor this time delay is from 0 to 60seconds.continued
