TheanalogoutputcircuitontheHCUandICU_HPOoptionalboardsaregalvanicallyseparatedfromthegaugeelectronics.

Thissection(analogleveloutput)describesthesettingsforanalogleveloutputforboththeHCUandICU_HPOboard.FortheHART communicationoftheICU_HPOboard,refertoinstructionmanual973SmartRadarLT®

HART communicationoutput.®

5.1.1 HCUanalogoutputcharacteristics

Theanalogoutputispassive,henceanexternalpowersupplyisrequired.Thevoltageoftheloopsupplyshouldbeatleast12Vdc,andmaynotexceed64Vdc(measuredattheterminalsofthegauge).

Theloopresistanceisthetotalresistancefromtheloop,andhenceincludessupplyoutputresistance,totalcableresistance(includingseriesresistor)andtheinputresistancefromreaderoranaloginput.

ToreducethepowerdissipationontheHCUboard,anexternalresistormustbewiredinserieswiththeloopincasetheloopsupplyvoltageishigherthan30Vdc(refertofigure5.1A).Thepowerratingoftheexternalresistancedependsonthevalue;werecommend:1W/kΩ.

5.1.2 ICU_HPOanalogoutputcharacteristics

Theanalogoutputcanbeseteitherpassiveoractive(refertosection5.2.1).Whensettoactive,thesupplyvoltageintheloopis:20Vdc(±5%).

Thevoltageoftheloopsupplyshouldbeatleast8Vdc,andmaynotexceed64Vdc(measuredattheterminalsofthegauge).Supplyvoltagesover30Vdcrequireanexternalseriesresistor(refertofigure5.1B).

Note:HART communicationrequiresaminimumloopresistanceof250Ω.®

ThemaximumloopresistanceforHART communicationis1100Ω.®

ThisimpliesthatforHART communicationtheminimumsupplyvoltageis14Vdcandthemaximumsupply®

SettingtheanalogoutputlooptoactiveorpassiveisdonebyselectingthecorrectconnectorontheICU_HPOboard.Standard,theSmartRadarLT’saredeliveredwiththeanalogoutputloopsetas“passive”.Hence,anexternalsupplyvoltageisrequired.

Whentheanalogloopshouldbesetto“active”,theconnectorontheICU_HPOboardneedstobechangedfromposition.Thatprocedureisdescribedbelow.
