1.OverviewNo Static Long Range System

The No Static Long RangeSystem is a set ofcomponents used toneutralize electro staticcharges, without airassistance, over a relativelylong range. In comparisonwith conventional electrostatic dischargers, basedon low frequencytransformer designs, whichhave an effective range of acouple of centimeters atmost, the No Static LongRange System has aneffective range ofapproximately 1 meter.

In many of today'smanufacturing processes,electrostatic charges are anincreasing problem due tohigh processing speed, lowweight of the processedmaterial and the use ofcompounds that is moresusceptible to static chargebuildup. Many times it isnot practical or evenpossible to remedy theseproblems with conventionalelectrostatic dischargeequipment because of theirlow operating range andthe limited space within theprocessing environment. Inthese cases Liros No Static

Long Range System is theideal safe and simplesolution. The longoperating range allows it tobe placed at some distanceaway from the problematicarea where it doesn'tinterfere with the actualmanufacturing processesin the machine. The NoStatic Long Range Systemis also very well suited forapplications where thedistance between thedischarger and the staticbuildup varies, for instancewhere large reels are beingwound or unwound.

A complete systemconsists in one CentralControl Unit and up to fourhigh voltage ElectrostaticDischarger Units. TheCentral Control Unit ismains powered andprovides distributed lowpower to each ElectrostaticDischarger Unit.

The only control on thefront panel is a powerswitch which makes it veryeasy to operate. Nocomplicated settings toadjust - simply power it on

and leave it alone.

The ElectrostaticDischarger Units aresupplied with low voltagepower from the CentralControl Unit. The highvoltage is producedentirely within theDischarger Units whichmeans that the connectingcables can be relativelylong and of a commontype, making theinstallation easy. This is incontrast to many otherhigh voltage electrostaticdischarger equipmentswhich require high voltagecables that can be of verylimited lengths and isdifficult to install.

The high voltage generatedin the ElectrostaticDischarger Units is of suchlow power that it is totallyshock proof according toprevalent safety standardsand regulations. Inaddition, the high voltageemitters are shaped in away that reduces thenatural wear andbreakdown caused by thehigh voltage. The shapealso makes it easy to cleanand sharpen the emitterson site. The ElectrostaticDischarger Unit design andtechnology is PatentPending.

3.Electrostatic Discharger UnitEDU/LR013.1. General Description

The ElectrostaticDischarger Unit is suppliedwith a low power voltagefrom the Central ControlUnit. This low voltage isinternally converted to highvoltages used to neutralizethe electrostatic charges. Ithas no operating controlsor indicators and the onlyconnections are to theCentral Control Unit and afunctional earthconnection.

Although the DischargerUnit generates a high


voltage of both positive andnegative polarity, themaximum output current islow enough to make ittotally shock proofaccording to prevalentsafety standards andregulations.

The Discharger Unitcontains supervisorycircuits that continuouslymonitor the output voltage.If, for any reason, theoutput voltage isn't present,the Central Control Unitcan notify external circuits

via relay outputs or othertypes of industrialcommunication.

Liros manufactures severaltypes of ElectrostaticDischarger Units. The onedescribed here is theEDU/LR01 which is themost commonly used.Consult the individualinstallation manualsregarding specific data andinstallation instructions forthe other types ofElectrostatic DischargerUnits.

3.3.2. Placement in a machine or process

Even though the Electro-static Discharger Unit it istotally shock proof, it canstill be very unpleasant todirectly come in contactwith the high voltageemitters. This could in turnlead to secondary injuries,when somebody by reflexmovement, quickly with-draws an arm for instance.Therefore it is preferred tomount the ElectrostaticDischarger Units in such away that its high voltageemitters are protected fromdirect contact with themachine operators.

Also make sure to notmount the Discharger Unitin a location or positionwhere objects, both metaland of other materials, canfall into the space in theDischarger Unit where thehigh voltage emitters arelocated.

The shortest distance

between the high voltageemitters and anysurrounding objects wherethe discharger is mountedmust be at least 50mm.

The EDU/LR01 is a longrange electrostaticdischarger which worksmost effectively with adistance of 150mm or morebetween the object to beneutralized and theDischarger Unit. Forshorter distances, eitherone of Liros standard shortrange Discharger Units or aDischarger Unit in the LongRange program specificallydesigned for shorterminimum distance shouldbe used.

3.3.4. Ozone concentration

The process of electrostaticdischarging with highvoltage can increase thelevel of ozoneconcentration in thesurrounding air. Long term

and repeated exposure toelevated levels of ozoneconcentration in the air isharmful to the human body.The ozone concentration aworker will be exposed to

around a machine orprocess is partlydependent on how manydischarger units are used,how close together theyare, how long they are

continuously running andhow far they are locatedfrom the worker and partlyby how large the premisesis where the machine orprocess is located and howquick the air is exchangedby ventilation.

In most countries laws andregulations dictates themaximum limits for varioustoxic substances, includingozone, that a worker can beexposed to (MAK-Wert inGermany for instance).Here it is the responsibility


of the employer to keep theworking environment withinthe given limits for the toxicsubstances. The ozoneconcentration can bereduced by changing thecontributing factors. Usingthe remote control functionto only have the dischargerunit on when it is needed isone way to do this. Anotherway is to increase theventilated air volume.

Make sure that the ozoneconcentration in theworking environment is

kept below permissiblelimits according to locallaws and regulations.

3.4. Electrical installation

3.4.1. Signal connection cable

The connection betweenthe Central Control Unitand the ElectrostaticDischarger Unit is donewith the SKHE/LR signalcable. Its plug is simplyplugged into the matingsocket in the DischargerUnit and secured with thefastening screw.

Always make sure to switchthe Central Control Unit offbefore an ElectrostaticDischarger Unit isconnected or disconnectedand never operate theDischarger Unit without alocal earth connection –See also paragraph 3.4.2.below.

The high voltage isgenerated entirely insidethe Discharger Unit and theconnection cable onlycontains voltages below30VDC. This means thatthere are no specialrestrictions for how thecable is mounted or fixed inthe application. Comparedto many other high voltageelectrostatic dischargerswho generate the highvoltage in a Central Unitand run this in special highvoltage cables to thedischarger elements, this isa huge advantage for theway it is done in LirosElectrostatic DischargerUnit.

See also paragraph 2.4.2.above for more informationabout the signal cable.

3.4.2. Local earth connection

The high voltage in theElectrostatic DischargerUnits/High Voltage Unitneeds a current path to alocal earth point in order tofunction correctly and withhigh performance. TheElectrostatic DischargerUnit hasa facility for an earthconnection in the sameend as the socket for thesignal cable. In order to geta good electrostaticneutralization effect it is ofhigh importance that thiscable is connectedcorrectly. It should be asshort as possible,preferably less than 2meters, and it has to befirmly connected in bothends. This is a functionalearth connection, not aprotective earthconnection, which shouldnot use cables with thesame colour and markingas a cables used for theprotective earth.

Not only does this meansbad electrostaticneutralization performancebut it can also create highEMF that disturbs sensitiveelectronic equipment. Itcan also damage theCentral Control Unit andthe Discharger Units

since currentmay instead flow from themains earth connection,capacitively coupledthrough the Control Unitand the DischargeUnit .

3.6. High voltage emitters

The high voltage emitters inLiros ElectrostaticDischarger Unit/and theloose electrodes differ inshape compared to manyconventional electro staticneutralizers. Theconventional method is touse needle shapedemitters. The sharper anemitter is, the easier it is forthe electrons to movebetween the emitter and themolecules to be ionized inthe air. However, thiselectron migration alsodeteriorates the tip of theneedle, making it lesssharp over time. Instead,Liros ElectrostaticDischarger Unit uses acircular, tube like emitter,where the free end issharpened. This way, a

much larger surface than asingle needle point is usedwhich takes longer todeteriorate. It is also veryeasy to sharpen with astandard countersinkertool.

3.5. Operating status

The ElectrostaticDischarger Unit

containscircuits that continuouslymonitor the high voltageoutputs. In case there areany faults that cause one orboth polarity of the highvoltage to disappear, forinstance emitters shortcircuited by foreignobjects, this iscommunicated to theCentral Controller Unitwhich in turn can notify a

/HighVoltage Unit

supervisory machinecontroller via relay outputsor other type ofcommunication.

The ElectrostaticDischarger Unit actuallysends an OK signalperiodically to the CentralController Unit instead ofan error signal. This meansthat if the ElectrostaticDischarger Unit/HighVoltage Unit stops workingin any way, even by a

disconnected or shortcircuited connection cable,the Central Control Unit willknow.

4.Operation andmaintenance

4.2. Maintenance

The No Static Long RangeSystem contains no partsthat are worn out and haveto be replaced under

4.2.1. Cleaning

Always make sure to switchthe power off with themains power switch beforecleaning the system.

Use a soft cotton clothlightly moistened with amild solution of detergentand water to clean thesurface of the CentralControl Unit and theElectrostatic DischargerUnits. Any strong solvents,such as thinner andacetone may not be usedsince it can dissolve thePVC and rubber materialsused in the system. PVC ismainly used within theElectrostatic Discharger

Unit, but also in the powerswitch and the front panelof the Central Control Unit.Rubber is used in variousgaskets to keep the ingressprotection at IP54. Strongsolvents can also dissolvethe print on the CentralControl Unit. Make sure todry the ElectrostaticDischarger Unitsthoroughly before power isapplied again.

It is especially important tokeep the space in theElectrostatic DischargerUnit where the high voltageemitters are located clean.Any foreign material or

substance within this spacecan seriously degrade theperformance of the unit.Even though theElectrostatic DischargerUnit can temporarilyoperate short circuited orarching, this condition maypermanently deteriorate thehigh voltage outputs ifsustained for a long periodof time. Note that evenmaterials that are notnormally conductive cancontribute to creeping ofthe high voltage betweenthe emitters, due to itssurface propertiesregarding high voltages.

4.2.2. High voltage emitters

In order to keep theelectrostatic neutralizationeffect at an optimum levelthe high voltage emittersmay need to be sharpened.To do this, a standardcountersinker tool may be

used. It has to be for 90°countersinking and have adiameter of at least 10mm.Always make sure to switchthe power off with themains power switch beforesharpening the emitters.

Also remove all residuemetal chips from theElectrostatic DischargerUnit when done with thesharpening.

4.4. Checking the high voltage output level

In case there is anyuncertainty about thefunction of the ElectrostaticDischarger Unit and theneutralization effect, the

output voltage can bemeasured to give a roughindication to weather theNo Static Long RangeSystem is operating as

intended or not. This canbe done in several ways,some of which aredescribed here.

4.4.1. Using a Static Detector

1. Switch the static detector off (release the button).2. Make sure the No Static Long Range System is switched on.3. Move the static detector at least 1 meter away from any active Electrostatic

Discharger Unit, including the one to be checked.4. Switch the static detector on (push the button).5. Move the static detector to a position about 20 cm away from the Electrostatic

Discharger to be checked. Position it at an equal distance to two of the high voltageemitters.

6. Verify that the static detector is indicating full swing between positive and negativepolarity at the same rate as the operating frequency of the high voltage polarityalternation.

4.4.2. Using an earthed wire

1. Switch the No Static Long Range System off.2. Connect a wire to the earth connection of the Electrostatic Discharger to be checked.

Do not disconnect the local earth wire used for normal operation.3. Switch the No Static Long Range System on.4. Approach the other end of the wire to one of the high voltage emitters.5. Verify that there is a bright white or light blue spark between the emitter and the wire

when the distance between them is approximately 20mm. The sparking should pulsewith the same frequency as the high voltage polarity alternation frequency.

6. Move the wire to an adjacent high voltage emitter and verify that it is sparking with thesame intensity and frequency at the same distance between the wire and the emitteras for the other emitter.

Note that this test method generates high radiated EMF that can disturb nearbyelectronic equipment. It can even disturb the Electrostatic Discharger Unit that ischecked. The disturbance can be noticed as a change of the operating polarityalternation frequency. Do not run this test for longer than necessary since the archingcan deteriorate the high voltage outputs if sustained for a long period of time.

4.4.3. Using a high voltage probe

1. Switch the No Static Long Range System off.2. Connect the negative measuring clip and the earth connection of a 1000:1 high

voltage probe to the local earth connection of the Electrostatic Discharger to bechecked.

3. Connect the positive measuring clip of the high voltage probe to one of the highvoltage emitters.

4. Connect the output of the high voltage probe either to a voltmeter or an oscilloscope.The voltmeter should have max and min detection of the input signal to reliably showthe voltage at the higher polarity alternation frequencies.

5. Set the voltmeter or the oscilloscope to measure a voltage of -5 to +5V.6. Switch on the No Static Long Range System.7. Verify that the voltmeter or the oscilloscope is showing a voltage swing either between

less than -2V and 0V for a negative high voltage emitter or above +2V and 0V for apositive emitter and that the period of the signal corresponds to the set high voltagepolarity alternation frequency.

The high voltage probe has to have a maximum working voltage of at leastor more to give accurate readings.
