1.1.Takingthesystemintooperation

Toactivatetheweighingsystem,turnitonusingtheon/off()keyontheterminal.

After3to5minutestheelectronicsandloadcellshavereachedtheoperational
temperature.Beforethis,inaccuraciesofuptoca.0.3%mayoccur.

Itisrecommendednottoliftloadsbeforethezero‐pointcorrectionhasbeenexecuted.

1.2.Powersupply

Thepowersupplytothesystemtakesplacethroughanexchangeablebatterypack.Note:
Forlegalfortradesystemsthepowersupplytothesystemtakesplacethroughafix
mountedbattery.

Withacompletelychargedbatterythetotalweighingtimeisabout35hours(onasystem
withoutaprinter).

Whenthevoltagelevelofthebatteryisrunninglow,thedisplaywillshow.Whenthe
“LO‐BA”indication  isshownfor1or2minutes,theweighingsystemswitchesoff
automatically.Itisstronglyrecommendedtochargetheemptybatterydirectlywiththe
suppliedcharger.

Inordertomaximizethelifetimeofthebattery,followthecharginginstructionsbelow
precisely:
1. Insertthebatteryintothechargermodule.Note:Forlegalfortradesystemsconnect
thechargercabletothesystem
2. Plug‐inthechargeradaptorplug,intomainsvoltage220‐240VDC.TheredLEDonthe
chargeradaptorislittoindicatethatthechargerischargingthebattery.When
charging,itisnecessarytochargethebatteryforatleast6hours.Thiswillprevent
lossofbatterycapacity.
3. Anemptybatterywillbefullychargedafterapproximately6hours.Whenthered
LEDturnsoff,thebatteryisfullycharged.Itisnotpossibletooverloadthebattery
becausethechargerswitchesoffautomatically.
4. De‐connectthechargeradaptorplugfromthe220‐240VDCmainsvoltage.
5. Aftertakingoutthechargeradaptorplug,directlyremovethebatteryfromthe
chargermodule.Note:Forlegalfortradesystemsdirectlyremovethechargingcable
fromthesystemafterremovingtheadapterfromthecharger.
6. Forcharginganextbattery,startatstep1again.
Ifyouusethesysteminshiftworkorifthesystemhasabuilt‐inprinter,itisrecommended
topurchaseasupplementarybatterypack.

Wrongwayofliftingtheload

Correctwayofliftingtheload

Theaccuracyoftheweighingsystemdiminisheswithcirca0.1%perdegreestartingfroma
tiltedpositionof2°.Thiseffectalsooccurswithpits/pot‐holesinthefloor.Anevenflooris
optimal.Thesystemwillbeproducedwithanelectricallevelswitch.Whentheforksareout
oflevelwithmorethan2degrees,theindicatorwill
display‐‐‐‐‐‐
.


Themostaccurateweighingresultisobtainedwhenthecentreofgravityoftheloadis
placedbetweentheforks.Withannon‐centricloading,theforkswilltordateandbend.This
mayresultinahigherinaccuracy.Withlegalfortradeversions,thelevelcontrolwillswitch
offtheindicatorwithanon‐centricloadingoratiltedpositionthatinfluencestheweighing
accuracy.



Temperaturerange:between‐10and+40°
Cthemaximuminaccuracyis0.1%ofthe
weighedload.Outsidethisrange,
inaccuraciesofupto0.3%mayoccur.

Fasttemperaturechangesmustbeavoidedbecauseitwillcausecondensationintheelectronics.
Duringacclimatisationtheweighingsystemmustbeswitchedoff.

1.3.Maintenance

Themaintenanceguidelinesfornormalpallettrucksapplytothechassisofthemobileweighing
system.Fromexperienceweknowthattheintegratedweighingsystemstillfunctionswhenthe
chassisisdamagedbyoverloading.

Mainguidelines:
‐ Becausethesteeringwheelsaremountedinthefront,pullingofthepallettruckispreferred
abovepushingit.
‐ Whentheliftingmechanismisnotused,thehandleshouldbekeptintheneutral,middle,
position.Thisprolongsthelifespanofthesealings.
‐ TheweighingsystemmeetsuptotheprotectionclassIP65.Thismeansthatdustormoisture
(rainorwaterbeamfromallsides),willnotinfluencetheoperationoftheelectronics.
However,high‐pressurecleansingincombinationwithwarmwaterorchemicalcleanserswill
leadtotheentryofmoistureandthereforenegativelyinfluencetheoperationofthesystem.
Incaseofastainlesssteelchassisyoushouldneveruseadetergentthatcontainschloride,
otherwiseyouwillgetbrownspotsonthechassis.
‐ Onlyspecialistsmayundertakeanywelding.Thisistoavoiddamagetoelectronicsandload
cells.
‐ Thebearingsofthewheels(non‐polyurethane)andthepivotingpointsofthelevellingbarof
theloadingwheelsmustbecleansedandgreasedregularly.


1.4.MobileWeighingsystem

Amobileweighingsystemisamobilescale.Thismeansthattheownershouldconsiderthesame
maintenanceasapplicablewithstandardstationaryscales.

Ayearlyinspection,byanauthorizedserviceprovider,isrecommended.Andincasethescaleis
stamped‘legalfortrade’thentheweighingsystemshouldbere‐stampedinaccordancewiththe
metrologicalregulationsinthecountryofuse.

WhenyourcompanyisISOcertificated,itisverylikelythatallmeasuringdevicesshouldbe
checkedmoreregularlythanonceayear(i.e.½yearor¼year).Foraneasyoverviewyoucanfill


Basedontheserecommendationsweareconvincedthatyourmobileweighingsystemwillwork
accuratelyandreliablyforaverylongtime.

3.2.Beforeweighing:checkzeropoint

Beforeeachweighingitisnecessarytocheckwhetherthesystemisunloadedandfree.The
indicatorisfittedwithanautomaticzerocorrection.Thismeansthatsmalldeviationsofthezero
