Under-guaranteeservice isperformed bythe servicedepartment ofthe production plant, orbya
contracted service centreaccording to a written claim.
In case ofoccurring ofanyfault pleaseletusknowitand state:
•type code
•serialnumber
•ambient parameters (temperature, humidity...)
•dutycycle including frequencyofswitching
•type ofswitching-off (position ortorque)
•set switching-off torque
•type offault -description ofclaimed fault

1.5.1 Lifetimeofactuators
The lifetime ofan electricactuator(EA)isat least 6 years.
EA used forclosing mode (closingvalves) complywiththe requirementsforat least 15,000 working cycles
(cycle C –O– C at 30 revolutionsperoperating stroke:formulti-turnEA)
EA used forregulating/modulating operation (controlvalves) complywith the belowstatednumbers of operating
hours at the totalnumberof1 million start-ups:
Switching frequency
max. 1,200 [h-1] 1,000 [h-1] 500 [h-1] 250 [h-1] 125 [h-1]
Minimallifetime expectancy– numberofoperating hours
850 1,000 2,000 4,000 8,000
Time of netoperation ismin. 200 hours, max. 2,000 hours.
Lifetime atoperating hours dependson loadingandswitching frequency.
Note :High switching frequencydoesnot ensure betterregulation. Setting ofregulation parameters should be
therefore made with the inevitablynecessaryswitchingfrequencyneededforthe process in question
1.5.2 Lifetimeofsingle-phase electricmotors:
There are single-phaseelectricmotors fromSIEMENS-range ILF7 ... with run and start capacitorbuilt-in
version ofactuators with single phase electricmotor. The manufacturerguarantees100.000startsforthe 4 pole
electricmotors (approx. 1400 rpm/min).
Attention: Reversing ofactuators in design with thosesingle phase motors ispossibleonlyafterthetotalstop of
the output ofactuator. Otherwise, there maybe a continuationofthe movement ofthe output ofactuator, even
afterthe reversing process in the direction what wasbefore the reversing process. Maximumnumberofmotor
stop can be 500 perhour.
Estimated dutycyclesofactuators equipped with thoseelectricmotors feelfree to consultwiththeSales
department ofREGADAs.r.o.

Warning:
1. It isnot acceptable to storeEA outdoors, orinareasnot protected against direct climate influence!
2. It isnotrecommendedtoset upthe electricactuatormanuallywithout mechanicconnectionwitharmature.
The electricactuatordoesnot havemechanicrestriction of workingstrokeinterminalpositionsand therefore
can afterexceedingof the stroke come to mistuningofparameters set up byproductionplant.
3. Eventualdamagesto surface finish remove without delay– thuspreventing damage bycorrosion.
4. If storingtakeslongerthan1year,itisnecessary to inspectlubricationfillingsbeforeputtingEAinto

5. Assembled EA,but not putinto operation isnecessary to protectbythe equivalent method asduringstorage
(forexample suitable protective cover).
6. Afterassemblyto the armatureinfree and wet areas,orinareaswith temperaturechanges,connectwithout

3.Installation and dismantling ofactuator
Abide by safety measures!
Notes:
Repeatedlyverifywhetherplacing of EAcorrespondentsto part "Operating conditions". If actualconditions
differfrom recommended, itisnecessary to consultit with manufacturer.
Before starting of mounting the EA onto the valve:
•Checkagainwhetherthe EAwasnot damaged during storing.
•Checkwhetherthe adjusted operating speedangleand connectingdimensionsofthe actuator(see the
nameplate)are in compliance withthevalveparameters.
•In case ofinconsonance, performadjusting according to the partAdjustment.
3.1Installation
The actuatorisset up bythe manufacturerto the parameters according to labeltag, with connecting
dimensionsaccording to relevant dimensionaldrawingand isset tomid -position.
Put on the handwheelbefore assembly.
3.1.1Mechanical connection tothearmature
In casethatrequiredshapeofmechanicalconnectionisdesigned byA-shape adapter(withflangeF16,
F14 orF10),resp. C-shapeadapter(withflange F14)at firstis necessaryto fixthisadapterto connecting flange
ofEA bythe screws.
Mechanical connection – shape of connecting element B, C, D,E(eventuallyB3)and gearclutch:
•Bearing surfacesofEAconnecting flange must be carefullyde-greased.
•Slightlygrease the shaft ofarmature/gearboxbyacid-free grease;
•ShiftEA to itsterminalposition „CLOSED“; shift armature into identicalterminalposition.
•Put EAon armature, so asoutput shaft reliablyfitsintoclutch ofarmature.
Warning!
Donot use force whenyouput EA on armature, otherwisethe gearcanbe damaged!
•Should there isthe necessitytosynchronizethe openingsintheEAflange and armature, turn the EAbyhand
wheel;
•Verify,whetherconnecting flange fitstightlyto the armature / gearbox.
•Attachthe flangebyfourbolts(withmechanicalhardness min. 8G),whichsteadilytighten crosswise.
•Atthe endofmechanicalconnection perform thecheck of properconnection with thearmature, by
turning hand wheelinthe„open“direction.
Mechanical connection – rising spindle (forshapeA, C resp. B3):
•Ifthe rising spindle ofarmature isin terminalposition „open“longerthan dimension ofmounting flange up to
the controlboxcover, disassemblycoverofoutputshaft (Fig.1)on controlboxand replaceitbycovering
pipe (not partofdelivery)afterassemblyofelectricactuatoron armature.
•Seating surfacesofEA connecting flange and armature carefullyde-grease.
•Slightlygrease the output shaft ofarmature.
•ShiftEA to terminalposition „CLOSED“; shift armature into identicalterminalposition.
•Slide electricactuatorbyoutput shaft/nut onthespindle/nut ofarmatureand turnbyhandwheel
counterclockwiseuntilconnectingflangeofelectricactuatorfitstoconnecting flangeofarmature. Further
procedureisidenticalto previouspart ofmechanicalconnectionforshapesB, C, D.
•Atthe endofmechanicalconnection performthe checkof properconnectionofEA with thearmaturebytur-
ning the hand controlwheelwheelinthe „open“direction.
Note:
It isalso possible to fixtheEA on the wallconstructionusingthethree feeders located at the boxexternalwall,
opposite to the hand wheel.
