care", to save life and health ofusers and to avoid materialdamagesand exposure environment to danger.
1.Generaldata
1.1Purpose andapplications
Electriclinearactuators(hereinafter EA)of ST0 (hereinafter ST)or STR0 (hereinafter STR)
types arehigh-powered electric-mechanicalproductsdesigned fordirectinstallations ontocontrolled
devices (regulating bodies -valves,etc.). EA ofSTtypes areprovided forremotecontrolofclosing
bodies,and EA ofSTRtypes forautomotivecontrolofregulatingbodies inbothdirections oftheir
movement.Theycan beequipped withmeans ofmeasuringand controloftechnologicalprocesses
wherean unified analogue directcurrent or voltagesignalisan informationbeareron theirinput and/or
output.Theycan be used inheating,energy,gas,air-conditioningand othertechnologicalsystems,
which theyaresuitablefor, regardingtheir features. Theyareconnected withcontrolled devices witha
flangeaccording toDIN3358, or usingapillar or flange.
Note:

1.5.1Lifetimeofactuators
Thelifetimeof an electricactuator(EA)isat least6years.
EA used forclosing mode (closingvalves) complywiththe requirementsfor at least 15,000 working
cycles (cycleC–O –C: for linear EA).
EA used forregulating/modulatingoperation (controlvalves) complywiththe belowstated numbersof
operatinghours atthetotalnumber of1million start-ups:
Switchingfrequency
max. 1,200[h-1] 1,000 [h-1] 500 [h-1] 250 [h-1] 125 [h-1]
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: Highswitchingfrequencydoesnotensurebetterregulation.Settingof regulation parameters
shouldbe thereforemadewiththe inevitablynecessaryswitchingfrequencyneeded for the processin
question.
1.6Operation conditions
1.6.1Productlocation and operation position
Electricactuatorsmaybe installed and operated inenclosed locations ofindustrialfacilities with
no temperatureand moistureregulation,protectedfromdirect climaticeffects(such as directsunlight).
Moreover, special“marine”versions maybe used inwastewatertreatmentapplications,water
management,selected chemicalapplications,tropicalenvironmentsandcoastalareas.
EA havetobe placed withthe viewofaccess towardhandleofmanualoperating,top coverand
bushing.Installation andoperation of EAispossiblein anyposition.
Warning:
WhentheEA isinstalled inopen air, itmustbe sheltered lightlytoprotectisagainstdirect
effectsofatmosphere.
Wheninstalled inthe areas withrelativehumiditymorethan 80%,inopen airundera
shelter isneeded toconnectthe space heaterdirectly–without athermal switch.

1.7Description
The STelectricactuatorsaredesigned forautomotiveposition controloflinearvalves where
relativelysmall controlthrustis
required.Theycan be also used in
air-conditioning,heatingas wellas
intechnologicalsystems.
The actuatorsaredriven with
an electricmotor(1)fed and
controlled throughtwothrust
switches (2). The thrustswitches
areswitched withafinger(5).The
position switches areswitched with
motion ofthecams(4).
The actuatorsarecontrolled
withconnection ofvoltagetothe
correspondingactuatorterminals.If
the voltageisconnected tothe
terminals1and 12 ofthe two-
thrustsversion (the thrustswitches
S1and S2), or1and 20 ones in
case oftheone-thrustversion (the
position switch S3and the thrust
switch S2), the actuatoroutputpart
performslinearmotion inthe
direction „opening“.The motion inthedirection„closing“can bereachedwithconnectionofvoltage to
the terminals1and16.
Inaccordance withthe orderthe controlpart can also containaposition transmitter(6)(resistive
orwiththe unified currentorvoltageoutputsignal)functioningasafeedback orasaremoteposition
transmitter.The remoteposition transmitterwiththe unified outputsignalconsistsofthe 2000 Ω
resistivetransmitterand the electronics board.Thetransmitterrotation isderived fromtheoutputshaft
throughthegearwheelssystem(7).
Incase ofmains failureorswitches damages theactuatorcan be operated manuallyfollowing

Abidebysafetymeasures!
BeforestartingofmountingtheEA ontothevalve:
•Check againwhethertheEA was not damagedduring storing.
•Checkwhetherthe adjusted operatingstrokeandconnectingdimensionsofthe actuator(see the

2.1.2Electricconnection and checking offunction
1. Followinstructionsin thepart "Requirementsforprofessionalqualification"!
2. Whilelaying electricalline abidebythe instructionsforheavy current installations.
3. Cablesto terminalboardsorconnectors lead throughcableglands.The cablejacket diameters must
conform to the extent specifiedinChapter1.8.3!
4. Before initiation ES into operation internaland externalprotection terminalsare needed to be connected.
5. Feeding cablesareto befixed to the solidconstruction atmost150 mm from the cable glands.
6. It isrecommended to use screened cablesto connect remotetransmitters.
7. Topreventmoisturefromentering the actuatoraround theconnectingcables,the cablesmustbesealedwith

Connecting withthemastersystem:
TheEA canbe controlledwith:
•abuilt-inpositioncontroller
•an externalpositioncontroller
The actuatorisconnected inaccordancewiththe wiringdiagramsputintotheactuatorupper
cover. Electricconnection ismade throughcableglands tothe terminalboards.The terminalboard
withsixterminals(9)(Fig.1)isdesigned forconnection and controloftheactuatorand the terminal
boardwiththree terminals(10)forconnection ofthe transmitter.The installed setofcapacitors(8)
allowsstartingof theactuator.
Afterelectricconnection it isrecommended:
Check ofwiringoftheelectricmotorandthecontrolpart: Settheactuatorintoamid-position.
Check therightdirection ofoutputshaftmovement withpressingof thebutton „closing“(onthemanual
controlboxor onthetestpress-button box), andfollowthe outputstem which shouldshift outfromthe
actuator.If not you checkproper connection.
Check oftheposition switch: Whentheactuator ismovinginthedirection„opening“switch the
contactofthe switch withpressingof itsswitchingspring.Incase of proper connection the actuator
shouldstop.If anyof thefunctions isnotproper, checkwiringofthe switches inaccordance withthe
wiringdiagram.
Inthe STR version withthe built-inelectroniccontrolleritisneeded toperform autocalibration for
assuring optimalfunctioning.
Theprocedureisas follows
Press the button SW1 forabout2sec (i.e.till the D3 diodeisgoton)tosetthe controllertothe
autocalibration mode.Duringthisprocessthecontrollerchecksthe feedback transmitterandthe
sense ofturning, putstheEA tothe positions openand closed,measures inertiamass inthe directions
"opening"and "closing", and loads the adjusted parametersintothe EEPROMmemory.Incase that
duringthe initialisation process an erroroccurs(e.g.inconnection oradjustment) the initialisation
process will be interruptedand the controller withthe D4 diode reportsabout the type ofthe error. Else
afterfinishingthe initialisation process the controllerisputintothe regulation mode.Ifneededto
changeadjustedparametersof thecontrollerfollowinstructions given inthepart Adjustingof actuator.
2.2Dismantling
Beforedismantling itisrequiredtodisconnecttheEA frommains!
Donot connect anddisconnectliveconnectors!
•Disconnectthe EA from mains phases.
•Disconnectthe leadsfromthe EA terminalboardsand loosenthecables fromcableglands.
•Loosen the fixing screwsofthe EAflange and ofthe coupling anddisconnectthe EA fromthe valve.
•Whilesendingthe EAtobe repairedputit intoapackagesolidenoughtoavoiddamagesof theEA
