1.8Packaging, Transport, Storing and Unpacking
The EAMO aredelivered insolidpackages, assuring the resistanceaccording tothe requirementsof
standards ČSN/STN18 0004, ČSN/STNIEC60654-1and ČSN/STNIEC60654-3.
The package ismade byabox.The productsinthe boxescan be packed on pallets(the palletis
returnable). The following information isgiven on the outside ofthe package:
· the producer
· the nameand the type ofthe product
· numberofpieces
· otherdata–inscriptionsand labels.
The forwarderisobliged toprotectthe packed productsloaded intotransportmeansagainst
spontaneousmotion, incaseofan open transport mean theyaretobe protected againstrainfallsand

position, avoidpossibilityofmutualbumpsand bumpsagainst the wallsofthe transport means.
The transport innon-heated and non-pressurized transport meanswithconditionsinrange:
- temperature: -25°Cto+70°C(specialversions–45°Cto+45°C)
- humidity: 5to100%withmaximumwatercontent of0.028 kg/kgofdryair
- barometricpressure: 86 to108 kPa.

Afterreceiving oftheEAcheck whetherduring theirtransportorstoring no damage
occurred.Comparethedataon theirnameplateswiththeaccompanying documentation/the
purchaseagreement(theorder).Incaseofanydiscrepancy,failureordamageinformabout
thefacttheproducerimmediately.
Ifnot installed immediatelythe EA and theirequipment shouldbe stored indry,well-conditioned
sheltered areas,protected against impurities, dust and soil humidity(withkeeping themon shelvesor
pallets),chemicaland unauthorized impacts,atambienttemperaturefrom-10°Cto+50°Cand at
relativeairhumiditymax. 80 %.
a)It isforbidden tostoreEA outside orin areasnot prevented against direct impact of climate.
b)Strainsofthe surfacefinishing should be promptlyremoved ifany–itcan preventthe product
against corrosion damages.
c) While storing morethan one yearitisnecessary tocheck lubrication filling beforethe actuatoris
put intooperation.
d)The EA installed but not operated aretobe protected the samewayaswhen storing (e.g. withawrapping).
e)Afteritismounted ontoavalvein free and wetareasorin areaswheretemperatureischanging itis
necessary toconnectthe spaceheater–topreventthe actuatoragainstcorrosion resulted fromwater
condensed in the control part.
f) Removeodd conservation greaseaslateasbeforeputting intooperation.
1.9Liquidation oftheProductand thePackage
The productismade ofrecyclable.The singlepartsof the package and the productshouldnot
be thrownawayafteritslifetimebutsorted according tothe related regulationsand rulesabout
environment protection and delivered fornext treatment.
The product itselfaswell asitspackage isnot asourceofspoiling ofenvironmentand theydo
not containanydangerouswaste.
2.Installation and Dismantling oftheActuator
Followsafetyregulations!
Note:
Check againwhetherthe EA isplaceinaccordancewiththe Chapter“Operation Conditions”.If the
installation conditionsaredifferentthan recommended itisneeded toconsultthe situation withthe
producer.
Beforestarting the installation ontothe valve:
· Check againwhetherthe EA wasnot damaged whilestoring.
· Check complianceofthe strokeadjusted bythe producerand the connecting dimensionsofthe EA
withthe parametersofthe valve.
· Incaseofanydifferenceperform the adjustment according tothe Chapter“Adjustment”.
2.1.1Mechanical connection
EA isbythe produceradjusted toparametersaccording tothe nameplate,withconnecting
dimensionsaccording tothe corresponding dimensionaldrawing and put it toamid-position.
Beforeinstallation put the handwheelon.
Mechanical lever-jointconnection
· Properlydefat contact surfacesofthe EA, connecting flange and the valve/gearing.
· Coat the valve/gearing output shaft firmlywithagreasenot containing anyacid.
· Reset the EA tothe limit position "closed"; put the valvetothe samelimit position.
· Put the EA ontothe valvetohavethe output shaft reliablyinthe valve/gearing coupling.
· Usethe handwheeltoturnthe EA if needed toreachcompliancebetween holesinthe EA flange
and the valve.
!

12 MP 52 200
· Check whetherthe connecting flange clingstothe valve/gearing.
· Fixthe flange withfourscrewstightened toallowmoving ofEA.Then the fixing screwstighten
uniformlycrosswisely.
2.1.2Electricconnection and checking offunction
Followup withconnecting the EA withmainsormastersystem.
1. Followinstructionsin the part "Requirementsforprofessional qualification"!
2. While laying electrical line abide bythe instructionsforheavy current installations.
3. Cablestoterminal boardsorconnectors lead through screwbushings.
4.Beforeinitiation ES intooperation internal and external protection terminalsareneeded tobe
connected.
5. Feeding cablesaretobe fixed tothe solid construction at most 150 mm fromthe bushings.
Checking ofsupplyconnection
· Connect asupplycabletothe actuatorand check whetherphasesareconnected properly.
· Press the button SB2"open"on the controlboard.The outputstemshouldmove
counterclockwiselylooking tothe output shaft fromthe controlchamber.
Ifthe powersupplyisreversed itisnecessarytopress the button "stop"and change phases
connection. Then perform the check again.
Checking ofthetorqueswitches
· Press the button SB2"open"on the controlboard.The outputshaftshouldmoveinthe direction
"open".
· Press the lever(42)inthe direction tothe output shaft, what switchescontacts(20)MO (S1)and
the actuatorshouldstop.
· Press the button SB1"closed"on the controlboard.The outputshaftshouldmoveinthe direction
"closed".
· Press the lever(42)inthe direction fromthe outputshaft, whatswitchescontacts(21)MZ(S2)
and the actuatorshouldstop.
Checking oftheposition switches
· Press the button SB2"open"on the controlboard.The outputshaftshouldmoveinthe direction
"open".
· Press the spring (36)toswitchcontactsofthe switch(37)PO (S3)and the actuatorshouldstop.
· Press the button SB1"closed"on the controlboard.The outputshaftshouldmoveinthe direction
"closed".
· Press the spring (36)toswitchcontactsofthe switch(37)PZ(S4)and the actuatorshouldstop.
Checking oftheindication switches
The indication switchesareordered asadditionalequipment. Ifnotagreed elsetheyare
adjusted tooperatenext beforepositions"open"and "closed".
2.2Dismantling
Beforedismantling itisrequiredtodisconnecttheEAfrommains!
Donotconnectand disconnectlive connectors!
· Disconnect the EA frommains.
· Disconnectthe leadsfromthe EA terminalboardsand loosen the cablesfrombushings.Pull out
the connectorsincaseofthe connectorversion.
· Loosen the fixing screwsofthe EA flange and disconnect the EA fromthe valve/gearing.
· Whilesending the EA tobe repaired putitintoapackage solidenough toavoiddamagesofthe
EA during transportation.

100 W.
· Switchthe converter¢spowersupplyon.
· Turnthe adjusting trimmerZERO(Fig.6)toadjustthe

Note:
The outputsignal of4-20mA can be adjusted atthe range from75 up to100% ofthe rated strokestated on the
actuator ¢ snameplate. At valuesless than 75% the value 20mA isreduced proportionally.

4.Service, maintenance and troubleshooting
4.1Service
1.Ingeneral itisprovided thatserviceofthe EA isperformed byaqualified workerin accordancewith
requirement given in Chapter1!
2.Afterputting the EA intooperation itisneeded toverifywhetherduring manipulation anyscratchon
surfaceoccurred, it istobe removed toprevent actuatoragainst corrosion!
The EA SP/SPRrequiresjust negligibleservice. Properputting intooperation isarecondition of
reliableoperation.
The serviceofthe EA leadsfromthe operation conditionsand usuallyresidesininformation
processing forfurtherarranging ofrequired functions.
The stuff hastoperform prescribed maintenancetopreventthe EA during operation against
impactsofenvironment, whichexceed the frameofallowed influences.
4.2Maintenance -extentand periodicity

Everysixmonthsitisrecommended toperform one check moveinframeofadjusted operation
stroketoverifyreliabilityoffunctioning withsetting back tothe originalposition.
After6monthsand onceayearit isrecommended tocheck tightening offixing screwsbetween
the EA and the valve/gearing.
4.3Troubleshooting
Atfailureof powersupplythe EA stopsinthe position whereit wasbeforethe failure. Ifneeded
the EA can be setonlywiththe manualcontrol(the handwheel).Afterrestoration of powerthe EA is
prepared foroperation.
Incaseof failureof anyelement ofthe EA it can be changed byanewone. Entrust the change
toaservicecentre.
Incaseofan EA failure,whichcannotbe eliminated directlyinoperation,followinstructionsfor
under-guarantyand after-guarantyservice.
Note:
If the EA requiresdismantling followthe chapter"Dismantling".
Taking theEAtopiecesforrepairpurposesisallowedonlybyprofessionallyqualified
personstrainedintheproduction plantorbyacontractedservice centre!
