Abidebysafetymeasures!
Note:
Check againifplacement ofEA replyto chapter"Operationconditions".Incasethat operation conditions
are different from recommended, consultationwith producerisneeded.
BeforestartingofmountingtheEA ontothevalve:
Check againwhethertheEA was not damagedduring storing.
Checkwhetherthe adjusted operation strokeand connectingdimensions ofthe actuator(seethe
nameplate)areincompliance withthe valveparameters.
Incaseof inconsonance,perform adjusting accordingtothe part"Adjustment“.
3.1Mechanical connection
EA isby the produceradjusted toparametersaccordingtothe nameplate,withconnecting
dimensions according tothe correspondingdimensionaldrawingand put it toamid-position.
Beforeinstallation putthehand wheelon.
3.1.1Mechanical flangeconnection
•Properlydefatcontactsurfacesof the EA,connecting flangeand the valve/gearing.
•Coat thevalve/gearingoutputshaft firmlywithagrease not containing anyacid.
•Resetthe EA tothelimitposition "closed"; putthevalvetothe samelimit position.
•Put theEA ontothe valve tohavethe output shaftreliablyinthe valve/gearing coupling.
•Use the handwheeltoturnthe EA ifneeded toreach compliance betweenholes inthe EAflange
and thevalve.
•Check whetherthe connecting flangeclingstothevalve/gearing.
•Fixthe flangewithfourscrews(withmechanicalruggedness min.8G) tightened toallowmovingof
EA.Then the fixingscrewstightenuniformlycrosswisely.
3.1.2Mechanical leverconnection
•Clean contactsurfaces ofthe stand and the base and coatthe EA shaftand the pull-rods sliding
surfaceswithgrease.
•Fixthe EA tothedevice withtwoscrews.
•Putthe controlled devicetothe limitposition;putthe EA withstop ends tothe correspondinglimit
position.
•Putthe leveroranotheroutputelementcorrespondingwiththe positionas much as possible,in
case thatthe positionisnotincompliance with
required,tuneit withthe handwheelinrange± 15°.
•Connectthe EA withthe device withthe pull-rod
consistingoftwoball pinsand a1/2" tube accordingto
STN425711 threadedonbothends.
•InEA withoutstop endsoperation anglepositioncan
be adjustedwiththe handwheel,alongthe whole
circumferencewithout changingof setting of thelever.
•Whileinstallingtakecaretohavethe anglebetween
the leverandthe pull-rod atleast15°and atmost165°
(Fig.1).
Notes:
1. Minimum mechanicalruggedness of screwsis8G.
2. If adjustment of the position-signallingunit,thetransmitterortheposition indicatorintheproductionplant do
not correspond withtheEA connected thisway,adjustthe units.If adjustment ofthestop endswas
changed, it isneeded to adjust the stop end screwsagain.
•Inthe end ofmechanicalconnection checkcorrectness ofthe connectionwiththe valve/gearing

the two-wiretransmitterloop to electricalearth of the successive externalcontroller!
2. Connection can be performed onlyin one point, inanypart ofloop out of theEA.
3. Electronics of the two-wiretransmitters isgalvanicallyinsulatedthat iswhyitcan serveasan

source can supply).
4. Do not connectanddisconnectliveconnectors)!
Connecting toterminalboard
•Check whetherthetype ofcurrent,supplyvoltageandfrequencycorrespond withdataon the
nameplateofelectricmotor.
•Removethe upper cover.
•Incase ofthesingle-phase version the phase L1 and the lead Nconnecttothe corresponding
terminals.Incase ofthethree-phase version connectthe phase cables L1,L2 and L3toU,V,W
(terminals2,3,4),the protection cables tothe marked places ofinternaland externalprotection

Theprocedureisas follows
Set theactuatortoamid-position (position andtorque switches arenot switched)
Press the button SW1 forabout2sec (i.e.till the D3 diode isgoton)tosetthe controllertothe
autocalibration mode.Duringthisprocess thecontrollerchecksthe feedbacktransmitterandthe
sense ofturning,putsthe EA tothe positions open and closed,measures inertiamass inthe
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
needed tochangeadjusted parametersofthe controllerfollowinstructionsgiven inthe partAdjusting
