1.3 Personnel
Onlyqualiedpersonnelmayworkonthislinearactuatororinitsvicinity.Qualiedpersons
aredeemedtobepersonswhoarefamiliarwiththeinstallation,assembly,commissioningand
operationormaintenanceoftheactuatorsandhavetheappropriatequalicationsfortheirjob.
Necessaryorprescribedqualicationsinclude,butarenotlimitedto:
● Training/instructionandtheauthorizationtoswitchelectriccircuitsanddevices/
systemsonandoffinaccordancewithEN60204(DINVDE0100/0113)andthe
technicalsafetystandards
● Trainingorinstructioninthecareanduseofappropriatesafetyandworkprotection
equipmentinaccordancewithsafetytechnologystandards.
● Firstaidtraining.
Workinasafemannerandavoidanyoperationthatwouldendangerthesafetyofpersonsor
damagethelinearactuatororotherpropertyinanyway.
1.4 Before starting work
Beforecarryingoutanywork,checkwhetherthetypesspeciedherecorrespondtothe
informationonthenameplateoftheactuator:
baelz 373-E45
1.5 During operation
Safeoperationisonlypossibleiftransport,storage,assembly,operationandmaintenanceis
carriedoutinasafe,properandprofessionalmanner.
1.5.1 Transport, installation and assembly
Observethegeneralinstallationandsafetyregulationsforheating,ventilation,airconditioning

2.5 Operating conditions
Incaseofextremevariationsinambienttemperatureandhighhumiditylevels,installationofa
heatingresistorisrecommendedtominimisecondensationintheactuator.
Actuatorcoverswithsuppressionofthermalbridges(dualcovers)arerecommended.
● Connecttheheatingelement(HZG)asshowninthewiringdiagram.
● Putthedeviceintoserviceassoonasitisinstalled.
Theactuatorsaresuitableforinstallationinindustrialplantsandinwaterworksandpower
plantswithalowpollutantconcentration.
Foruseoutdoorsorinanenvironmentwithahighpollutantconcentration,suchasheavytrafc
areas,industrialareas(chemicalplants,sewageplants,etc.),coastalareasandtheopensea,
theactuatorsmusthaveexternalpartsmadeofnon-corrosivematerialandmustbeprovided
withaspecialcoating.
Whenusedoutdoors,theactuatormustbeprotectedwithanadditionalcoveragainst
●rain
● directsunlight
● strongdraughts
● dust
3. TRANSPORT AND STORAGE
Risk of injury caused by failure to observe safety regulations!
Caution
● Weartherequiredpersonalandotherprotectiveequipment.
● Protectthelinearactuatorfromimpact,shock,vibrationandsimilarinuences.
● Storethelinearactuator(orthecompleteactuator/valveassembly)inadryplace.
● Observethetransportandstoragetemperaturelimitsof-20to+60°C.

4. ASSEMBLY
Make sure that the specications on the nameplate correspond to those in
the order documents!
4.1 Fitting position
Whenttingwiththeconnectingrodinhorizontalposition,tthelinearactuatorsuchthatthe
sidesoftheyokearepositionedoneabovetheotherintheverticalplane.
Risk of damage if no valve is tted to actuator!
Caution
Caution:
● Ifthelinearactuatorisoperatedwithoutavalve,themissingstopmaycausedamage
totheactuator.Theactuatormustthereforenever be operated without a valve.
● Allowforabout200mmspaceabovethecoveratthesiteofinstallation.
● Checktheworkenvironmentbeforettingtheactuatorandputtingitintooperation:
● Makesurethatthevalveiscorrectlyinstalled.Fordetailedinformation,refertothe
valve'sinstallationinstructions.
● Determinethemountingpositionofthelinearactuator.Donotmountlinearactuators
"headdown"belowthevalve.

4.2 Assembly with the valve
Priortoassembly,checkthat:
● theoperatingconditionscomplytothespecicationsofthelinearactuator.
● thevalveiscomplete(yokeonactuatororonvalve).
● theconnectionsonvalveandactuatormatch.
Thelinearactuatorissuppliedwiththespindleretracted.
Aslightadjustmentforttingofthecouplingcanbecarriedoutbyturningthespindle.The
followingdimensionsmustbeadheredto,otherwisedamagetotheactuatorcanensue.
Fig. 3: Assembly with the valve
Ensurethattheconnectingrodoftheactuatorandthevalvespindlearecorrectlyaligned.
Misalignmentcanleadtopowerlossandprematurewear.
Whensuppliedwithintegratedpotentiometerassembly,adjustmentoftheassemblymaybe
necessary.
Keep the spindle within the given
stroke range to avoid damage to the
actuator!

4.3 Principle of operation
Motorizedlinearactuatorstooperatecontrolvalvesforowregulationapplicationsincontrol
andprocesstechnology.Theself-lockingthreadedspindle/spindlenutisdrivenbyanelectric
motorviaagearbox.Thisconvertstherotarymovementintoalinearmovement.Load-
dependentlimitswitchesdictatetheendpositions
4.3.1 Manual adjustment
Manualadjustmentmayonlybecarriedoutwhenthemotorisnotinmotion.Forthe
adjustment,unscrewthecapnutfromthetopofthecover,removethehandcrankfromthe
bracketonthebottomoftheactuatorhousingandinsertitintothetubeinthetopofthecover.
Turnthecrankhandleusinggentlepressure.
