1.General Information
1.1Purpose andApplication
Electricmulti-turnactuators(hereafterreferredtoas EA), types SO2 are high performance electro-
mechanicalproducts,designed fordirectassemblyon controlled devices.EAofSO2types areprovided
forremotecontrolofclosingbodies.Theyareequipped bymeasuring and technologicalprocesses
controlling means;the informationcarrieron their input and/or outputisunified analogue directcurrent, or
voltage signal.Theycanbe usedinheating,energy,gas,air-conditioningandothertechnological
equipments,forwhich aresuitabledue totheirmanufacturingqualities.Theyareassembled bymeansof
flangeand connectingcomponent inaccordance withISO 5210, DIN3338, resp. GOST R55510.
1. It isforbidden to usetheEA asa lifting mechanism!
2. Switchingof actuatorbya semiconductorcomponents/switcheshave tobe consulted with
producer.
SafetyInstructions
EA of SO2 typesare reserved technicaldeviceswithhigherrateof danger, with possibilityof
installation in areasspecially dangerregarding casualtiescaused byelectriccurrent.
ElectricactuatorsareaccordingtodirectiveLVD2006/95/EC and standardEN/IEC 61010-1:2010
assignedfor installation categoryII (overvoltagecategory).
EffectsoftheProductsupon Environment
Electromagneticcompatibility(EMC): the productcomplies withthe requirementsoftheDirective
2004/108/EC ofthe European Parliamentand ofthe Council on the approximation ofthe lawsthe
MemberStates relatingtothe electromagneticcompatibilityand withthe requirementsof standardsas
well EN/IEC 61000-6-4+A1,EN/IEC 61000-6-2,EN/IEC 61000-3-2and EN/IEC 61000-3-3withinvalid
edition..
Vibrationscausedbytheproduct: the productinvokes negligiblevibrations
Noise producedbytheproduct: The maximum allowablenoice level(A)ofthe product measuredin
aplace of operation is78dB(A).
Requirementsforprofessionalqualification ofpeopleperforminginstallation, serviceand
maintenance
Electricconnection canbe performed onlybyan acquainted person,i.e.an electricalengineer
withprofessionaleducationofelectricalengineering atanapprentice schooloratechnicalschool
(secondary,completesecondaryoruniversityeducation)and whose qualification wasverifiedby
an educationalfacilityauthorised toverifyprofessionalqualification.
Instructionsforoperatingstuff training
Operationcan be performedbyskilled personalonlytrained byproduction plant, resp.by
contracting service center!
Warningforsafeutilization
Protection oftheProduct

1.4.1Lifetimeofactuators
Thelifetimeof an electricactuator(EA)isat least6years.
EA used forclosing mode (closingvalves) complywiththe requirementsfor at least 15,000 working
cycles (cycleC–O –C at 30revolutions peroperatingstroke:formulti-turnEA)
EA used forregulating/modulatingoperation (controlvalves) complywiththe belowstated numbersof
operatinghours atthetotalnumber of1million start-ups:
Switchingfrequency

Minimallifetimeexpectancy–number of operatinghours
850 1,000 2,000 4,000 8,000
Timeof netoperation ismin.200 hours,max. 2,000 hours.
Lifetimeat operatinghours dependson loadingand switching frequency.
Note: Highswitchingfrequencydoes notensurebetterregulation.Settingofregulation parameters

3.Installation and Dismantling oftheActuator
Follow safetyregulations!
Note:
Check againwhethertheEA isplace inaccordance withthe Chapter“Operation Conditions”.If
the installation conditionsaredifferent than recommended itisneeded toconsultthe situation withthe
producer.
Beforestartingthe installation ontothevalve:
•Check againwhethertheEA was not damagedwhilestoring.
•Check compliance ofthestrokeadjustedbythe producerand the connectingdimensions ofthe EA
withtheparametersofthevalve.
•Incaseof anydifferenceperformthe adjustmentaccordingtothe Chapter“Adjustment”.
3.1Installation
TheEA areadjustedbythe producertothe parametersstated onthenameplate.
Put on thehandwheelbeforeassembly.
3.1.1Mechanical Connection for FlangedVersion
•Defattheabutting areasofthe connectingflange ofthe EA valveor thegear carefully;
•Lubricatethe output shaft ofthe valve/gearwithagrease not containing any acids;
•Set theEA tothe limit position “closed”, setthevalvetothesameposition;
•Put theEA ontothe valve withthe outputshaftreliablystalled inthe valvecoupling/gear;
Attention! Donot adjust EAon anarmatureforciblybecause of damageofthegear!
•Use thehand wheeltoturnthe EA tofit theopeningsintheEA andvalveflanges if needed;
•Check whetherthe connecting flangeabutswiththe valve/gear.
•Fixthe flangewithfourscrews(withmechanicalstrengthmin8G)fixed the waythe actuatorcan
Bemoved.Tighten the screwsequallyincross.
•At theendcheckthecorrectnessof thefixturewiththevalvewithrotatingthe hand wheel.
3.1.2ElectricConnection withMainsor Checking ofFunctions
Followup withconnecting theEA withmains ormastersystem.
1. Follow instructionsgiven inthe Chapter“RequirementsforProfessionalQualification...“!
2. Whilelaying electricallineabide bytheinstructionsforheavy current installations.Powersupply
cablesmustbe of the typeapproved. Minimumthermalresistanceof powersupplycablesand
wiresmustbe +90°C.
3. Cables shouldbe brought to terminalboardsorconnectors with cable screwed cableglands!

powersupplyand frequencycorrespond withthedataon theactuatornameplate.
Electricconnection:
•The electricconnection shouldbe realized accordingtothe wiringdiagramstuckintothe case of
the EA;
•Theelectricconnection shouldbe performedthroughtwocableglands seeNo. 2.2.1;
•Once electricalservices arecompleted puton thecoverand fasten itevenlycrosswise bybolts.
Fasten the cableoutletstoensurespecified shielding.
Electricconnectiontoconnector:
•Checkwhetherthe type ofcurrent,powersupplyand frequencycorrespond withthe dataon the

•Loosen theconnectorbodies;
•Bareendsof cables;
•Use therecommended tongs*toconnecttheconnectorsocketsontothecableends;
•Fixthe connectorsand tighten;
•Tightenthecableleadstoassuretheprotection enclosure.
Notes:

Follow instruction of producersofvalves,whetherswitching off inthe limit positions should
be arranged bytheposition ortorque switches!
AftertheEA iselectricallyconnected it isadvised tocheck functions:
•Afterthe EA iselectricallyconnected tocheckthecorrectfunctions oftheposition and the torque
switches S1-S6and ifneeded adaptthe orderofthe singlephase leads forthe 3-phase electric
motor.
•Set thevalvemanuallyintoanmid-position.
•Connectthe powersupplytothe terminalD2forsupplyingthe EA inthe direction “opening”and
followthe direction oftheposition indicatorrotation inthe controlpart ofthe EA .When EA is
connected correctly,the position indicatorof EA,lookingfromabove,mustrotateinthe direction of
symbols„open“or„closed“and atthe sametimethe outputcomponentofEA mustmovetothe
direction „opens“.If not it isnecessarytochangethe phase leads L1 and L3on the terminals2and
4mutually. Afterthe exchangeismade checkthedirectionof theEA rotation.
•Ifanyof the functionsisnotcorrect,checktheswitches whethertheyarewired properlyaccording
tothe wiringdiagrams.

Attention! See chapter1.2
Ifitis necessaryto connectthesupplyvoltageto Electricactuator,makesurebyfollowing the
mentionedprocedurethatthereis no injurycausedbytheelectriccurrent.Otherwise,
disconnecttheElectricactuatorfrom the electricity network.
Observe safety regulations!
After mechanicalconnection, electricalconnectionand checkingof connection and function start

4.1AdjustmentoftheTorqueUnit
Theswitching- off torques areadjustedbythe producerforbothdirections, i.e.for the direction
“opening”(thetorque switch S1) aswell as forthedirection“closing”(the torque switch S2)tothe
specified value withtolerance of ±10%.If notstated else theyareadjustedtothemaximumrate.
Adjustmentandchanging of settingsofthe torqueunittoothertorquevalues ispossibleusing
the adjustersaccordingtoFig. 2.Theswitching-off torque canbe onlyreduced withturningthe
adjustingscrewswiththescaleagainstthe adjustmentlines on the torqueunit arm.Setting tothe
longestline meansthatthe switching- off torque issettothe maximum value. Settingtothe lower line
means reducingofthe switching- off torque.

The signalingswitches ofEA areatproducerpresettoswitch on about10%beforeend positions
provided the customernotspecified otherwise.Beforeproceedingwithsignalingswitches adjustment,
S3,S4end position switches mustbe adjusted accordingtothe previous chapterifnecessary.The
procedureof signalingswitches adjustmentisasfollows:
•Check thatthe adjusting wheelofthesignallinggearboxisadjusted totherequiredlevelofthe

•BringEA toaposition inwhich You wantS5switch toclose when EA isrunninginthe „open"
direction.
•Turncam(31)of S5switch (27) clockwise until S5switch closes.
•BringEA toaposition inwhich You wantS6switch toclose whenEA isrunninginthe "close"
direction.
•Turncam(30)of S6switch (26) counterclockwiseuntil S6switch closes.
Notice: Thissignalingiscapabletosignalisefrom50 up to100%..of theworking strokeinboth movement
directions. With switchreversing function, a signalingcapabilityfrom 0 up to 100%isavailable.
