Inspection
TheModel915EXBarwascarefullypackedatthefactory.Nevertheless,we
recommendcarefulexaminationofthecartonandcontentsforanydamage.Ifdamage
isevident,keepthepackingmaterialandimmediatelynotifythecarrierofapossible
damageclaim.Shippingclaimsmustbemadebytheconsigneetothedelivering
carrier.
SpecialConditionsforSafeUse
1. TheModel915EXmustbeusedinconjunctionwithaMeechType904power
supplyor904CMsystem.
2. Thepowersupplyshallbeprotectedbyafusecapableofwithstandinga
prospectiveshortcircuitcurrentof4000A
3. Theusermustdetermine,inconsultationwithMeech,thesuitabilityofthe
apparatusforusewithanysolventspresentattheapplication.
4. Whenusedindustyenvironments,theequipmentmaynotbeusedinassociation
withdustshavinganelectricalresistanceequaltoorlessthan103 Ohm
5. Whenusedindustenvironments,theequipmentmaybeusedonlywithdusts
 requiringanignitionenergyofgreaterthan0.2m.J.
6. Theusermustdetermine,inconsultationwiththemanufacturer,thesuitabilityof
 theapparatusforusewithparticularsolvents.

Operation
ThetypicalMeechModel915EXinstallationconsistsofoneormorebarsconnected
toaMeechModel904PowerUnit.
ThePowerUnitconvertstheelectricalsupplyintoahighvoltage,lowamperage
output.Thisoutputenergyistransferredtothe915EXbarbytheHTcable.
TheresistivelycoupledelectrodesareenergisedbytheACvoltagefromthePower
Unit.Theelectrodesemitthisenergy(coronadischarge)intheformofafieldof
ionisedair.Thisionisedairsuppliesionsofbothpolarities.
Electrostaticallychargedproductswhichpassthroughthiscoronaareimmediately
neutralisedandbecomestaticfree.
Undertestconditions,theMeechModel915EXhasbeenfoundtogivechargedecay
timesthatareuptoeighttimesfasterthanstandardACshocklesseliminatorbars. 5

Installation
The915EXBarcanbeplacedbetween25mmand150mmfromthesurfacetobe
neutralised.Itisimportanttoensurethatthesurfacetobeneutralisedhasfreeairon
bothsidesandthatearthedmetalobjectsare,wherepossible,atleast20mmaway
fromthebar.Theseprecautionswillmaximisetheunit’sionisationcapability.
Goodresultscanbeachievedatdistancesupto150mmbutasthedistancefromthe
objectincreases,thespeedofchargeneutralisationwilldecrease.
Atypicalinstallationdistanceis50mmfromthetargetsurface.Thisgivesexcellent
performanceathighweborproductspeeds,whilstavoidingpossibledamagefrom
webbreaksorproductmis-feeds.Veryfastwebsmayrequirethebartobeasclose
as25mmtotheweb.
Correctpositioningofthebar(s)isvitaltoefficientoperation.Thefollowingdiagrams
showthecorrectinstallationprocedures:
1.Theoptimaldistancefrommaterialtobeneutralised.

Mountingofthebarisby20mmM4studsmountedinatrackattherearofthebar.
Thesecanbeslidtoanypointalongthebar’slengthtomeetthemachine’savailable
fixingpoints.
Thechassisofthebariselectricallyconnectedtogroundonthepowerunitviathe
flexiblearmouredconduit.However,itisgoodpracticetoprovideasecondary
groundingthroughthefixingpointswherepractical.
TheHTcableandarmouredconduitrequireconnectiontoaMeechmodel904power
unit.Pleaseconsultthe904instructionmanualforfurtherinstruction.
NB:Meechmodel904powerunitisnotATEXratedandhencemustbemounted
outsidethehazardouszone.Forthisreasonastandard5mHTcableisprovidedbut
thiscanbeextendeduponrequest.
1. Freespaceisrequiredonoppositesidesofthetargetmaterial,notarollerorsolid
object.

2. Avoidproximitytoearthedpartsofmachineryasthiswilldistortthecoronaand
reduceitse󰀩ciency.
3. Ifbarsareneededonbothsidesofthematerial,theyshouldbe
staggered.
4. Thebarsmustbeearthedforcorrectoperation.Ifinanydoubtrunanearthwire
fromthebartotheearthstudonthePowerUnit.

Maintenance
Ionisersrequireperiodiccleaning.Duringnormaloperation,dirtwillbuild-upon
theemitterpinsanduponthebodyoftheioniser.Thiswillcauseareductionin
performance.
Typically,weeklycleaningissu󰀩cient.However,equipmentusedinsomeheavy
contaminationareas,suchasgravureprintingorwhereplasticfumesarepresent,may
requiredailycleaning.Equally,inaClass100area,cleaningmayonlyberequiredon
amonthlybasis.
Beforecleaning,ensurethattheequipmentisswitchedo󰀨.
Emitterpinscanbecleanedverye󰀨ectivelywithabrush.Adrytoothbrushisideal.
Ionisingbarswillneedperiodicwipingtocleangreydepositsfromthesurface
ofthebar.AclothmoistenedwithasmallamountofIPAormethylatedspiritsis
recommended.Allowamomenttodrybeforeswitchingon.
ShouldyouhaveanyadditionalquestionsregardingthemaintenanceofMeech
equipmentpleasecontactMeechInternationaldirectlyoryoulocalMeechdistributor.

FaultFinding
Testsmustbecompletedbyaqualiedelectricalengineer.
IfindoubtpleasecontactMeechheado󰀩ceoryourlocaldistributor.
CAUTION:
Whilstnodangertopersonnelexists,itisessentialthat,withtheexceptionofbars
withawaterresistantoption,highvoltageionisingequipment,makesnocontactwith
waterorwaterbaseduids.Shouldsuchaneventoccur,disconnectimmediatelyand
returnequipmenttothemanufacturerforwaterdamageassessment.
TheModel915EXionisingbarformspartofasystem,comprisingthebaritselfanda
Model904PowerUnit.
Toverifywhereafaultmayhaveoccurreditisimportanttotesteachitemofthesystem
individually.Shouldmorethanonebarbeconnectedtoapowerunit,thesemustbe
testedindividually.
TochecktheModel915EXbarfollowtheproceduredetailedbelow.
1. Switcho󰀨theelectricalsupplytothesystemanddisconnecttheIECplug.
11

12
2. Disconnectallionisingbarsfromthepowerunit.
3. FollowthetestprocedurefortheModel904PowerUnit.Thiscanbefoundinthe
instructionmanualoftheModel904.

4. Havingcheckedthepowerunit,reconnectoneModel915EXionisingbar.
5. Usingahighvoltageprobeandmetermeasurethevoltageonthepinsofthe
ionisingbar.Thisvoltageshouldbeapproximately6.5kV.
CAUTION:
Thistestmustonlybecarriedoutwhentheinstallationareaisnon-hazardous.This
mayrequirethebartoberemovedfromitsnormalinstallationposition.
6. Ifthevoltageisbelow4.0kVthenthebarshouldbereturnedtoMeechforservice
and/orrepair.
7. Ifthereismorethanonebartotest,disconnecttherstitemandrepeattheabove
stepswithsubsequentbars.
