Abidebysafetymeasures!
Note:
Check againifplacement ofEA replyto chapter"Operationconditions".Incasethat operation conditions
are different from recommended, consultationwith producerisneeded.
BeforestartingofmountingtheEA ontothevalve:
•Checkagainwhether the EA was not damaged during storing.
•Checkwhetherthe adjusted operation strokeandconnectingdimensionsofthe actuator(see the
nameplate) areincompliance withthe valveparameters.
•Incase ofinconsonance,performadjusting according tothe part "Adjustment“.
3.1Mechanical connection

3.1.1Mechanical flangeconnection
•Properlydefat contact surfaces ofthe EA, connectingflangeand the valve/gearing.
•Coat the valve/gearing output shaft firmlywithagrease not containing anyacid.
•Reset the EA tothe limit position "closed"; put the valvetothe samelimit position.
•Put the EAontothe valvetohavethe output shaft reliablyinthe valve/gearing coupling.
•Usethe handwheeltoturnthe EAifneededtoreach compliancebetweenholesintheEAflangeand

•Checkwhether the connecting flange clings tothe valve/gearing.
•Fixtheflange withfourscrews(withmechanical ruggedness min.8G) tightened toallow moving ofEA.
Thenthe fixing screwstighten uniformlycrosswisely.
3.1.2Mechanical leverconnection
•Clean contactsurfaces ofthe standandthe baseand coatthe EAshaftand the pull-rodssliding
surfaces withgrease.
•Fixthe EA tothe device withtwoscrews.
•Putthe controlled devicetothe limitposition;putthe EAwithstop endstothe correspondinglimit
position.
•Putthe leveroranotheroutputelementcorresponding withtheposition as much aspossible,incase
thatthe position isnotincompliance withrequired,tune
it withthe handwheelinrange ± 15°.
•ConnecttheEAwiththe devicewiththepull-rod
consisting oftwoball pinsand a1/2"tube accordingto
STN42 5711 threadedonbothends.
•InEAwithoutstop ends operationangleposition canbe
adjusted withthe handwheel,alongthe whole

3.2Electricconnection and checking offunction
Follow up withconnectingthe EA withmains ormaster system.
1. Followinstructionsin thepart "Requirementsforprofessionalqualification"!
2. Whilelaying electricalline abidebythe instructionsforheavy current installations.
3. Cablesto terminalboardsorconnectors leadthrough screw bushings.

5. Feeding cablesareto befixed to the solidconstruction atmost150 mm from the bushings.
Connecting withthemastersystem:
TheEA canbe controlledwith:
•abuilt-inpositioncontroller
•an externalpositioncontroller

(capacitiveorresistivewithaconverterintwo-wireconnection),itisneeded to arrange connecting of the
two-wiretransmitterloop toelectricalearth of the successive externalcontroller!
2. Connection can be performed onlyin one point, inanypart ofloop out of theEA.

Theprocedureisas follows
Set theactuatortoamid-position (position andtorque switches arenot switched)
Press the button SW1 forabout2sec (i.e.till the D3 diode isgoton)tosetthe controllertothe

directions "opening"and"closing",and loads theadjusted parametersintothe EEPROMmemory.In
case thatduringthe initialisation process anerroroccurs(e.g.inconnection oradjustment)the
initialisation process willbe interrupted and the controllerwiththe D4 diode reportsaboutthe type of
the error. Else afterfinishingthe initialisation process the controllerisputintothe regulation mode.If
