Introduction

Recommendationsandregulations given inthe installationmanual are referredto fuel level

sensorsDUT-E (hereinafter DUT-E),developedbyJV Technoton CJSC,Minsk,Belarus. This

document definestheprocedureforinstallationandconnectionof DUT-E,aswell as

providesguidance/recommendations ontheoperation.

DUT-E are used foraccurate measurement ofliquidfuellevelinthevehicle tanksand in

fixed/immovabletanks.

DUT-Ecanbeusedasa standardsensorofthefuel-levelindicator,aswellas apartof the

fuelconsumptioncontrolandvehiclemonitoring systems.

Distinctivefeaturesof DUT-E:

−deliveryset includesallnecessaryitemsforthe properinstallation and

connection, incl. mountingplate, connectingcable, rubbergaskets, screws andseals;

−supply voltage range is from 10 to 50 V;

−possibility toreduce the length upto 30% without calibration*;

−possibility toincrease thelength byusing the additionalsectionsofDUT-E;

−thermo-correction with adjustable coefficient allows tomake automatic updating of

measurements basedontheambient temperature **;

−easy bayonetfastening allows youto installandremovethesensorwithout any tools;

−bottomspringstop serves to give extra stiffness for sensormounting;

−openingsforsealing will help to prevent theunauthorized demounting or operating

troubles of DUT-E;

−self-diagnostic check of DUT-Eallows to controlthe sensor operation.**

1.3.4 Characteristics of outputsignal for DUT-E 232 and DUT-E 485

Characteristicsof output signalof DUT-E232 andDUT-E485 correspond tothespecification

of interfacesof RS-232 andRS-485 accordingly.

Factory interface settings: 19200 bit/s, 8bit, 1stopbit.

Otherfactorysettings aregiveninAppendix4of this manual.

Speedof data exchange via digitalinterfacecanbechosenfrom thefollowing values:4800,

9600, 19200 bit/s.

Theresults of DUT-E measurements canbetransferred via digitalinterface as:

a) standardunits, from0to 1000 (0-emptytank,1000 - fulltank);

b) fuellevelinthetank, mm;

c) fuelvolume, l;

d) fuelvolumeinrelationto thefulltank, %.

Besidesthe remaining fuel amount in the tank,DUT-Epassesinformationabout current

temperature(measuredbythesensorlocatedon the electronic board).

Information transfer is carriedout accordingto DUT-ECOMprotocol.

2. Installationand set-up

This chapter provides basic recommendations for the DUT-E installation.

Beforeyou start,youshouldmake external check of thevehicle for any possible failures

andmakeInspectionActof thevehicle (seeAppendix 1)

2.1 Exterior examination before startingof works

Beforeyou start,youshouldmake external check of DUT-Efor any possibledefectsthat

occurredduringtransportation, storageorcarelesshandling:

a) visible damage ofthehousing,measuringpart,mountingplate,rubber gaskets,signal

cableorconnector;

b) tubeplay of themeasuringpart in relation to eachotherand/or to the housing.

By discoveringanydefects, please,contact theproduct supplier.

DUT-Ecanbeinstalled as intotheopeningof the standardfuelsensor* as intoa special

opening inthetank.

*Studycarefullytheschemeof the mountingopeningsforthestandardfuelsensorand

comparewiththeDUT-Einstallationscheme(SeeFigure 9).

ATTENTION! By installingthesensor youshouldfollow safetyrules of the repairworks on

automotive vehicles aswell as safetyrequirements prescribedbytheenterprise.

2.2 Installation on theplaceofa standard fuel sensor

ATTENTION! It is not recommended toinstallthe DUT-E on the place of a standard fuel

sensor because ofitsfarlocation from the geometric center of the tank, and as a result,

inaccuracy in the fuel levelmeasurement may occur. Thereasonforthatissignal

fluctuationof DUT-E thathappens becauseof fuelflowinginsidethetank.

BeforetheDUT- Einstallationit isnecessaryto remove the standard fuelsensorandclean

the installationplace (seeFigure 2)

manual.

2.3 Installation into a specialopening

ATTENTION! Beforedrilling the holesinthetank youshould dismantleit, evaporate oradd

water.

ATTENTION! Beforeyoustartdrillingthehole,please,makesurethatthere are no

partitions insidethetankundertheselectedlocation, whatcanpreventDUT-Einstallation.

Installationsteps:

a) Identify the place where it is supposed to install the sensor. Itisrecommendedtochoose
