i-maticACTUATORS WITH INTEGRAL CONTROLAND NON-INTRUSIVE SETTING

Valve actuators for multiple applications

Wherever material flows through pipelines in liquid,gas or powderform,several kinds of valvesare usedto shutoff or to regulate therate of flow or pressure.For reliable remote operation of thesevalves,whethertheybe globe，gate，ball orbutterflyvalves ordampers,DREHMO have been successfully employed electromechanical actuatorsall over the world for several decades.

Ouractuators are used in power generation,water industry, oil and gas marketaswell aschemical and petrochemical process industry.Actuators have to move the valve to a mechanically definded final position or tointermediate positionsand avoid excessive torque that overload the valveduringtravelbetweenthefinalpositions.Accordingthisspecial devices ensure that the actuator is switched off in dependence of the position,angle of rotation or torque.Special variants include part-turn actuators and thrust actuators,which transform the torque into an axial thrust by means of a thrust unit.

Overview

MULTI-TURNACTUATORS

PART-TURNACTUATORS

THRUSTACTUATORS

Thedesign principleof multi-turn actuators isto turnamultipleof 360 degreesat the output drive.

Theyare designed to operate valveswith 2 up to 1450 revolutions per stroke.

Multi-turnactuatorsarefitted mainly to gate andglobevalveswhichtransformthemultiple rotation of theactuator'soutputdrive into linearmovementviaa threaded spindle.

Flangesand output drive designs of the multi-turn actuatorsare standardizedin accordancewith DINEN ISO5210or DIN 3210 respectively and therefore fit on any modern valve design.

Furthermore a multitude of special flange designs isavailable.The multi-turn actuators are classified in four housing sizes according to their rated torque:

·5 Nm to 60 Nm: actuator size Dim 30,59
·60 Nm-250 Nm:
actuatorsizeDim 60,120,249
·250 Nm-1000 Nm: actuatorsize Dim250,500,1000
·1000Nm-2000 Nm: actuator size Dim 2000

Torquevaluesexceeding 2oooNmarerealizedbyadditionalspurorbevel gearboxes.

Part-turnactuatorsareaspecial typeofmulti-turn actuator for operatingbutterfly，ballvalves ordamper,forinstance,withanoutputdrive movementof lessthan 3 6 0 ^ { \circ } Theinternal gearof the part-turnactuatorisdesigned foratravel range inbetween 7 5 ^ { \circ } and 1 0 5 ^ { \circ }

The mechanicaldesign ofthe part-turn actuatorsDPiM(R)75-1800isbased ona DPiM(R) 30actuatorwithan additional attached planetary gearstage
to adapt the actuator to the demands of the part-turn movement.

All the advantages of the planetary gear such as handwheel operation without changeover,self-locking gear, long service life,lifetimelubrication,aswellasthefeatures alreadydescribed,are likewiseapplicable to the part-turn actuators.

The flange dimensions and the different output drives,such as plug bush with bore and groove and square bore,all correspond to the usual standards,e.g.DIN EN ISO 5211. Thismeans that directmounting on thevalve is possible.Accessoriessuchasfootand lever with ball jointsmake indirect operation of butterfly valves possible depending on the structural and designconditions of thevalves. Torque values exceeding 180o Nmare realized by multi-turn actuators with additional worm gears.

DREHMO thrust actuators can befitted tovalveswhich require a linearmovement.The thrust actuator transforms the torque of a DREHMO actuator into an axial thrust bymeans of an integrated thrust unit.

Therequired actuating force (thrust or traction) can be adjusted continuously and reproducibly.Thrustactuatorsaremainly used to operate plug valves.

Thrust units fitted to the flange of a multiturn actuator consist mainly of a trapezoidal threaded spindle,a metric screw bolt to join the valve shaft and an enclosure to protect the spindle from environmental influences. Theversion described is used for direct mounting of the actuatorto thevalve. However,"fork joint"versionsof the thrust actuators(indirectmounting)primarilyoperatebutterflyvalvesforwhich directmounting ofa 9 0 ^ { \circ } part turn actuator is not possible orefficient for design reasons.Cardanic suspension of the thrust unitatthe fork joint is alsoavailable.

OPERATIONMODES-

OPEN-CLOSE,POSITIONINGANDMODULATINGDUTY

Valvesare driven in compliancewith the required application and theirdesign.Actuator standard EN15714-2 distinguishes betweenthreecases:

> Class A: OPEN-CLOSE duty.
Theactuator isrequired todrive thevalve through itsentire travel from the fully open position to the fully closed positionor vice versa.

> Class B: Inching/positioning or positioning duty. Theactuator is required to occasionally drive the valve to any position (fullyopen,intermediate and fully closed).

> Class C:Modulation ormodulating duty. Theactuator is required to frequentlydrive the valve to any position between fully open and fully closed.

SWITCHINGFREQUENCYANDMOTOROPERATIONMODE

Between Modulating dutyand open-closedutytherearedifferencesregarding to the mechanical loads.Consequently, special actuatortypesareavailable foreachoperationmode. The types of duty for actuators in compliance with DIN EN 60034- 1and EN15714-2are typical distinction criteria. For modulating duty,additional indication is made of the permissible number of starts.

Actuators with integrated positioner for modulating duty.

Gear design and operating functions

TheDREHMOactuators basically consist of amotor,planetary gear arrangedwithatorque-bearingdisplacementworm,a handwheel andan integrated control unit.All partsof the planetary geararearrangedaroundthe hollowshaft.Asseveral teethalwaysmeshsimultaneouslywith thisplanetary gear (unlikenormalworm gears),it is possible to realizeavery compact gearwitha long service life.

FUNCTIONALITYOFMANUALOPERATION

Changeover from motorized to manual operation isnot necessary. Duringmanual operation via the handwheel,the forcesare transmitted viathewormshaft(9),thesunwheel (11) and theplanetwheel (4) to the driver plate (5), the hollow shaft (10) and the stem nut (6).

FUNCTIONALITYOFMOTOROPERATION

The motor (1) drives the eccentric (3) via the spur gear (2).The planet wheel (4),which meshes into the inner gear of the sun wheel (11), ispivotedontheeccentric (3).Asthe twowheels haveadifferent number of teeth,a relative speed is generated which is transferred by driver pins (12) to the driver plate (5),which ismounted on the planet wheel (4).The driver plate (5) is interlocked with the hollow shaft (10) via serration.

TORQUEMEASUREMENT

Inadditionto theinner gear toothsystem,thesunwheel (11)also hasan outer gear tooth systemwhich mesheswith the axially displaceable wormshaft (9).Thewormshaft (9)isheld in itscentral positionbya pretensioned spring (7).If a torque isexerted on the actuator higher than the torquecreated by the pretensioned springs, theperipheral force on the sunwheel (11) moves thewormshaft (9) from itscentral positionand therebyactuatesthe torque lever (8). Thetorque lever (8) activatesthecombined sensor(15).Therelated torquevalues can beused for the remote torque feedback indication.

FEATURESOFTHEGEAR

·Lifetime lubrication
·No mechanical switchover for handwheel operation is required
·Nostartingproblems,evenat lowtemperatures
·Long service life,even inmodulatingoperation,due to low surfacepressure combined with littlerelativemovement
between the meshing gears and optimum lubrication

COMBINEDSENSOR

Anelectronicpositionsensorisused forcontinuous position detection,including the detection of intermediate positions. Interacting with the i-matic control unit, the sensor switches off the actuator whenit reaches limit positions that have been electronically programmed and are nonerasable.

Atthe same time the sensor can supply isolated limitpositionsignalsandananalogue4-20 mA positionsignal.Asecond measuring input isusedtomakeananaloguerecordingof the torque reached,which is then compared and evaluated with settableswitch-off values in the control unit.Analoguemeasurement,signaling andevaluation of the torqueispossiblewhile the actuator is running.

Features

SELF-MONITORING

A self-monitoring process runs continuously in the actuator.To simplify troubleshooting,the process distinguishes between the following messages:

> Hardware fault
> Sensor fault
> Electronics fault
> Software fault
> Electronics temperature exceeded
> Motor temperature exceeded

Foundation Fieldbus (FF) wasexplicitlyadapted to the requirements of process automation.The distributed data transmission within the Foundation Fieldbusnetworkenablesfielddevicesperform automation tasks.Decentralization of automation to the field level relieves the central process control.Transmission physics of the FF H1 protocol usedatfield levelare basedon IEC 61158-2and ISA SP 50.02.These standardsdefine the framework for data transmission and energy supply of field devices using the same cable pair.FF H1 supports various topologies.In combinationwith junction boxes or segment barriers,variouswiring structuresare possible.Apart from conventional line and tree structures,FF H1 supports point-to-point topology or other structures with one trunk combined or individual spurs leading to the field devices.

EDDand FDT/DTMare two independent technologies for harmonisation of device integrationwithin fieldbus systems across all field devices.This includes for example device configuration, device replacement, fault analysis,device diagnostics,or documentation of theseactions.Forthis reason,EDDand FDTare crucial forPlantAssetManagementandLifeCycleManagementof a plant.

Besides the imperative main functions, field devices possess diagnostic functions and many specialised application functions to adapt the device to the processand environmental conditionsas required.If certain prerequisitesare fulfilled,for Profibus e.g.the DP-V1 protocol, data exchange connected to these functions can directly take place between control station and field device.For DREHMO actuators, this further includes statusand diagnostic signals in compliance (according toNAMURNE107onlyat Foundation Fieldbus& HART),parameter modifications of user functions,information of the electronic device ID or operational data for preventive maintenance. EDD or FDT isused to harmonise access from the control station to the dataavailable with the various field devices.

EDD

Each field device supporting thistechnologyisprovided withan EDD (Electronic Device Description).This file combines device parameters described in ASCll using standardised and platform neutral EDD language.This technology helps to createa uniformuser philosophy withidentical parameter visualisationacrossall field devices.

FDT/DTM

FDT (Field Device Tool) isa software interface definitionto integrate DTM (Device Type Manager) into the FDT system of the maintenance processor. DTM is a software module supplied by field device manufacturers.Similartoaprinterdriver,DTMis installed within the FDT frame applicationto visualise settingsand informationavailable from thefield devices.

COMMUNICATION-CENTRALFIELDDEVICEMANAGEMENT

DATATRANSMISSIONVIAFIBREOPTICCABLES

Long distances between the devices combined with the high demands fordata transmission security-in this instance,fibre optic cables area suited transmission medium.

Long distances

Lowattenuation of light signals in fibre opticcablesallows coverage of long distances between participants,resulting ina considerably higher total fieldbussystem length.With multi-mode cables,distancesup to 2 . 6 k m betweendevices can beachieved.

Integral overvoltage protection

Contraryto coppercables,fibreopticcablesareresistanttoelectromagnetic interference.Separated installation of signal cables and power cables isno longer required.Fibre optic cables provide galvanic isolation between actuators.This offers particular protection against overvoltages,for example in the event of lightning.

DREHMOactuatorswith fibre optic interface (FO)

FO module for converting actuator-internal electrical signals into fibre opticsignalsis integrated within the electrical connection of the actuator.Connection of fibre opticcables ismade via conventional FSMA plug/socket connectors.

When using Profibus DP,line,star and ring topology are possible. In this case,theavailabilityof the fibre optic ring is monitored.If the ring isinterrupted,awarningwillbe sent.Thiswarning is integrated within the signaling pattern of i-maticactuator controls,visualised on the display and transmitted to the control station in compliance with the specified signalling pattern.

SIMAisthe ideal masterstation forperfect integrationofactuators into a DCS.Entire communication is based on open fieldbus protocols.

> SIMA supports the user with a mostly automated procedure for commissioning the connected actuator network,irrespective of the DCS- plug and play. SIMAmanagesand monitors communication to field devices including all redundant data channels and hot standby components.
> SIMAasdata concentrator collectsall actuator status signalsand sends the signals relevant for normal service to the DCS.
> SIMA facilitates status information access to the connected actuators. Intheeventof failures,SlMA supportsfast fault identificationand remedy. SIMA servesthe purpose of gateway toadapt fieldbus communicationwithactuatorstotheavailable interfaces of the DCS

Configuration interface

1 SIMAMasterStation

SIMA combines standardised industrial PC components extended by required fieldbus interfaces.The entire hardware is housed ina robust 1 9 ^ { * } industrial enclosure with EMC protection.

1aHotStandbySIMA

Increased availabilityand reliability can beachievedby instaling a backup SIMA,takingoverall tasksof the primarySlMA incaseof failure.

2 Redundant Modbus loop

Themajoradvantage of this topology is the integrated redundancy.If theloop is interrupted,SiMA considers both segmentsas separate lines and allactuators remainaccessible.Actuators selected for this topology are equipped with a repeater function for galvanic isolation of loop segmentsand for Modbus signal amplification.Asa consequence,a total length of up to 2 9 6 k m can be achieved using a conventional RS-485cablewith maximum 247 participants.It isalso possible to implement line topologieswith SIMA.

3 Communication with DCs

DCScommunication is possible using Modbus RTU or Modbus TCP/IP.

4DREHMOactuators

DREHMO actuators are equipped with the suitable interface matching selected fieldbus protocol and topology. Individual devices can be separated from the fieldbuswithout interrupting fieldbuscommunication to other devices.

Advantages

> simple DCS integration
> reduction of the data volume to the DCS
> central level for control and diagnostic
> simplemaintenance for network loops
> additional operating function
> forcomplete diagnosticof the entireactuatornetwork.
