5.5 InitialLiquidSupply
Step1: Ifnotusingaprefilledcartridge,fillanemptyonewiththedesiredfluid,tillupto
80%ofitscapacity.
Step2: Insertthecartridgeintothecorrespondingholderandscrewitontotheluer‐lock
fluidboxconnector,rotatingclockwise.
Step3: Placethecompressed‐air
adaptorontothecartridgeandrotateclockwiseuntilit
latchesinplace.
Step4: ConnectthePVChosewithcouplerplugKS4‐CK‐6toairsupply.Acouplersocket
typeKD4‐1/2‐Aisrequired.

CAUTION!(checkforleakage)
Allofthepartsmustbeinstalledcorrectly,andthe
entireconfigurationmustbeleak‐tight–
otherwisethesubstancetobedispensedcantrickleoutinanuncontrolledmanner.

Step5: Afterestablishingaconvenientdispensingpressure,activatethepneumaticsupply.

ValvesdesignedbyVERMESMicrodispensingcanbeoperatedatarelativelylowsupply
pressure,intherange
between0and7bar.Thisupperlimitshouldnotbeexceededinnor‐
malapplications;inmostcasesevenavalueof4barissufficient.

Standardvalues:
 Low‐viscousfluids(e.g.water):0.5–1.5bar
 Mediumviscosity(e.g.SMT‐adhesives):1.5–2.0bar

Highviscosity(e.g.pastes):2.0–7.0bar

5.6 RemovingAirInclusionsfromtheSystem
Airmustberemovedfromthesystem,forinstanceaftertheexchangeofacartridge.
Savethecurrentdispensingparametersbeforehand(seepage36).

Confirmthefollowingparameterselection:
Rising0,5,OpenTime1,5,Falling0,17,Delay5–30,NeedleLift75andNumberofPulses500‐2000

Dispensea
quantityofca.500to2000portionsbypressing[trig].
Whenthismeasureiscomplete,retrievetheinitialparametersstoredbeforehand(see36),and
startthedispensingprocess.
5.7 ParameterInputandStart
Step1: Enterthedispensingparameters(eitherrecommendedbythemanufactureror
determinedinyourownexperiments)intothesubmenu“PulseParameters“of
thecontrolunit(seepage19).
Step2: Press[enter]toacknowledgetheselection.
Step3: Returntothefirstmenulevelbypressing[esc]repeatedly.
Step4:
 Startthedispensingprocessbypressing[trig].

INFORMATION!(Startingthedispensingprocess)
Adispensingprocesscanonlybeinitiatedinthefirstmenulevelbyalltheusualmethods.In
theotherlevelsitisonlypossiblewiththe[trig]key. 
