This allows moreaggressive tuning to co-exist withsmooth PV response. It does not change the PIDconstants, but temporarily modifiesthe internal controller response tosuppress overshoot. It operatesindependently from AccutuneIItuning. 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. 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. Third and fourth inputs availableas options. This automaticallycompensates for chart widthvariations caused by changes in theambient relative humidity.Analog Inputs - Two inputs forrecording and control on the HTSTmodel. You candesign the chart to match theirspecific application.“One-pen” Stylus Print Head -prints configurable alphanumericchart data including time and trendlines. 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.

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. All fourtraces share the same time line reference,which the Truline prints. Its “one-pen” stylusprinthead produces up to four analogtraces and prints alphanumeric chart dataon a blank heat-sensitive chart.
