Versions

Controls are required to operate anactuator and to process actuator sig-nals. In general, it is possible toinstall the controls externally in acontrol cabinet.

An actuator with integral controls isoften the better solution. Labourintensive design and installationcosts are considerably reduced and

an optimum functionality for theapplication are just a few of the manyadvantages. AUMA offers nearly alltypes of actuators with integralcontrols.

AUMA actuator controls are avail-able with a wide variety of equipment– from the simple OPEN – CLOSEcontrol to the microcontroller version

with logging of operating data or ver-sions with fieldbus interface.

Open-close duty

The usual valve positions inopen-close duty are the end posi-tions OPEN and CLOSED. Uponreceiving an appropriate commandthe actuator moves the valve to oneof the two end positions or, if neces-sary, to a pre-defined intermediateposition.

The valves are operated relativelyseldom, the time intervals can spanbetween a few minutes up to severalmonths.

Modulating duty

The controlled variable in a modulat-ing application is affected by manyinfluences. A change of the refer-ence input signal, pressure fluctua-tion in the pipeline and temperaturevariations influence the process insuch a way that a frequent adjust-ment of the MOV is required. Forsensitive modulating applicationsthe starts may be in intervals of a fewseconds.

Therefore high demands are placedon actuators for this duty. Mechani-cal components and the motor mustbe designed appropriately to with-stand a large number of operationswith no decline in the required modu-lating accuracy.

Types of duty for multi-turn actu-ators for modulating service(SAR, SARExC)

AUMA multi-turn actuators SAR formodulating service are rated forintermittent duty S4 - 25 %. Specialversions for S4 - 50 % and S5 - 25 %are also available.

Typical operation process in modulating duty

Comparison short-time and intermittent duty

Type of duty according to VDE 0530 / IEC 34-1Short-time duty S2

The operation time at a constant load is short, so thatthermal equilibrium is not reached. The pause is longenough for the machine to cool down to ambient temper-ature. The duration of the short-time operation is limitedto 15 min (10 min, 30 min).

Intermittent duty S4

The duty is a sequence of identical cycles which consistof starting time, operation time with constant load andrest period. The rest period allows the machine to cooldown so that thermal equilibrium is not reached. The rel-ative on- time at S4 - 25 % or S4 - 50 % is limited to 25 %and 50 % respectively.

Intermittent duty S5

Similar to S4, but with additional braking time. The brak-ing is carried out electrically, e.g. by reverse current.

Seating

Depending on the design of the valveto be operated, end position switch-ing either limit seating, i.e. by mea-suring the valve travel completed, ortorque seating, i.e. after reaching adefined torque. For this purpose, the

actuator is equipped with two inde-pendent measuring systems, i.e.limit switching and torque switching.

The type of seating has to be taken inaccount both when setting the actua-tor and in the actuator control. How-ever, the processing of signals forthe two types of seating differs.


Limit seating

The actuator runs at nominal output speed up to the settripping point P. Depending on output speed, actuatorsize and valve type, the combination has sufficient iner-tia to move the obturator further in direction of the endposition (overrun) after the motor has been switchedoff. In addition, the overrun also depends on the load.By selecting an earlier tripping point P, the overrun canbe accounted for in case of limit seating.

Torque seating

After starting from the end position OPEN, the actuatorruns in direction CLOSE. In end position CLOSED thetorque increases within the valve seat until the actuatoris automatically switched off after reaching the setvalue.

Overload protection against torque peaks

The torque switching, used fortorque seating in the end position(see page 10), serves as overloadprotection for the entire travel, evenin the case of limit seating.

If excessive torque builds up in thevalve in an intermediate position,e.g. due to a trapped object, thetorque switching trips after reachingthe set tripping torque.

After the controls have processedthe torque switch signal accordingly,the motor will be switched off. As aresult, valve and actuator are pro-tected from damage.

If the limit switch signals are pro-cessed accordingly in the controls,you can distinguish between a nor-mal torque switch tripping at the endpositions and tripping in an interme-

diate position (fault) caused byover-torque.

DUO limit switching/ intermediate position switches (option)

With DUO limit switching an addition-al switching point can be set for eachdirection of rotation (intermediateposition switches). The switching canbe set to any valve position betweenthe end positions.

The switch will remain operated fromset tripping point to end position if notmore than 120 turns of the hollowoutput shaft are in between.

The switch signal can be used forany purpose, e.g. to:

Limit and torque switches

With the help of the switches, themechanically measured travel (i.e.number of turns) and torque are con-verted into usable signals for theactuator controls. The switches areintegrated into the control unit whichcontains four switches in the basicversion:

■ one limit switch each for the endpositions OPEN and CLOSED,

■ one torque switch each for the di-rections OPEN and CLOSE.

The limit switches are tripped whenan end position is reached and thetorque switches are tripped when theset tripping torque is exceeded.

If the actuator is supplied withDUO limit switching (refer to page11) two more limit switches for inter-mediate positions are available.

To meet the high demands regardingreliability, AUMA uses speciallydeveloped high qualitymicroswitches with a snap actionmechanism.

In the basic version the switch con-tacts are of silver. For voltagesbetween 5 V and 50 V and low cur-rent, switches with gold-plated con-tacts are recommended.

Non-intrusive setting (option)

If the actuator is equipped with amagnetic limit and torque trans-mitter (see page 13) andAUMATIC integral controls (seepage 22) the actuator can be set

non-intrusively. This means thatthe parameters can be set without

having to open the actuator. Therebyseveral advantages are achieved:

■ No tools are required for setting.■ The actuator need not be opened

again after the electrical connec-tion is completed. The electronicand mechanical components inthe housing are well protectedfrom ingress of water and dust.

■ The actuator can be set in poten-tially explosive atmospheres,without affecting the explosionprotection.

13


Magnetic limit and torque transmitter (MWG) (option)

The magnetic limit and torque trans-mitter converts the mechanical val-ues of limit and torque into continu-ous electronic signals.

The simultaneous use of AUMATICintegral controls which evaluate thesignals is a prerequisite for the use ofthe MWG. This variant does not

require any switches for limit posi-tions or torque.

Actuators with MWG have the follow-ing advantages.

■ Non-intrusive setting is possible(see page 12)

■ A torque signal is permanentlyavailable. It can be used forswitching off at the set trippingtorque. It can also be transmittedfor external use, for example fortorque monitoring at the valve.

Absolute travel measurement –without battery

The valve position is determinedusing a so called multi-turn-absoluteencoder.Four shafts, each with a ratio of 8:1,are used to convert the travel into anelectronic signal. Each valve posi-tion is assigned an unambiguouscombination of the 4 shaft positions.Magnets and hall sensors registerthe shaft positions electronically.

As soon as the power supply hasbeen restored after a power failure,the current valve position is immedi-ately available; a reference opera-tion is not required. Position changesdue to manual operation duringpower failure are registered by theMWG even without supply voltage. Abattery is not required.

Torque – continuously available

The proven design of the slidingworm provides the mechanical prin-ciple of torque sensing. A torque loadat the actuator output drive results inan axial movement of the slidingworm against the spring action. Witha lever, the axial movement is trans-formed into a rotary movement. Hallsensors convert this movement intoan electronic signal.

Position/ torque feedback signal (option)

If the actuator is equipped with anMWG and AUMATIC integral con-trols, the valve position and therequired torque at the valve areavailable as output signals. Even ifthere is no MWG installed in the actu-ator, the position of the valve can betransmitted as a continuous signalfor remote position indication.

Position feedback is provided as ananalogue feedback signal by:

Design principle

MotorAn especially high starting torque isfrequently required to unseat valves

from the end position. The motors developedby AUMA fulfil this basic requirement.

Besides the commonly used 3-phase ACmotors, 1-phase AC motors and DC motorsare available for the actuator sizes up to 14.5or 16.1 respectively.

The motor is connected via an internal plug/socket connector (up to 16 A nominal cur-rent). This enables quick exchange of themotor, e.g. for change of output speed.

Further information on page 18.

Control unitDepending on the type of valve theactuator must be switched off in the

end position by limit or torque switching.

For this purpose two independent measuringsystems (limit switching and torqueswitching) are provided within the controlunit. They measure the travel or the torquedemanded at the output drive, respectively.

The switches signalize to the actuator con-trols that the set tripping points have beenreached, which then switches off the motor.

The control unit may optionally be equippedwith a magnetic limit and torque transmitter.The transmitter converts the mechanicalparameters limit and torque into continuouselectronic signals. In combination with theintegral controls AUMATIC tripping pointsand tripping torques can be set non-intru-sively, i.e. without using tools or opening thecontrol unit.

GearingThe well proven principle of wormgearing, sometimes combined with a

planetary gear, is used to reduce the motorspeed to the required actuator output speed.Worm shaft and output shaft with the wormwheel run in ample sized bearings.

The sliding worm is positioned between twostacks of springs on the worm shaft. Theworm will be moved in relation to the torque.This axial displacement, as a measure forthe torque, is transmitted to the control unitvia lever and gear wheels.

The gear housing is filled with lubricant. Thisresults in maintenance free service for a longperiod of time.

Design principle

Valve attachmentThe mounting flange is according toEN ISO 5210 or DIN 3210.

Various output drive types are available.Therefore it is possible to adapt to differenttypes of valves.


Manual operationFor commissioning or in an emer-gency, the multi-turn actuator can be

operated with the handwheel. By operatingthe red change-over lever the motor drive isdisconnected and the manual driveengaged. Since disconnection betweenmotor and drive shaft is made before theself-locking worm/ worm wheel, easychange over to manual drive is possible evenif the actuator has been operated at full ratedtorque.

When starting the motor the manual drive isautomatically disengaged. During electricoperation the handwheel does not rotate.

Electrical connectionThe connection for motor and con-trols up to size 16.1 are made on a

50-pole AUMA plug/ socket connector. Onlarger sizes, the motor is connected to termi-nals in the actuator.

If the plug/ socket is disconnected for mainte-nance work, the wiring remains undisturbed.

The explosion-proof actuator types SAExCand SARExC are provided with a specialplug/ socket connector for explosion-proofactuators as a standard.

Motors

3-phase AC motors

As a standard, AUMA actuators areequipped with 3-phase AC motors(TENV, pot-type motor without venti-lation).

AUMA has developed these motorsto comply with the special require-ments in valve automation. The mostsignificant features of this construc-tion are the high starting torque, thelow flywheel effect and the thermalmotor protection.

In order to protect the motor againstoverheating thermoswitches or PTCthermistors are embedded in themotor windings of the 3-phase ACand 1-phase AC motors. When inte-grated into the control circuit, theywill protect the motor against dam-age due to excessively high windingtemperature.

Thermoswitches and PTC thermis-tors offer better protection than ther-mal overload relays, since the tem-perature rise is directly measured atthe motor.

The thermoswitches will interrupt thecontrol circuit as soon as a windingtemperature of 140 °C is exceeded.After cooling down to a temperaturebetween 120 °C to 90 °C, the actua-tor can be switched on again.

Important! Failure to integrate themotor protection device into the con-trols voids the warranty for themotors.

If the actuator is equipped with inte-gral controls, the thermoswitchesare automatically integrated.


Delay time

The delay time is the time from thetripping of the limit or torque switchesto the motor power being removed.

To protect the valve against exces-sive peak torques, the delay timeshould be as low as possible. Thisshould be taken into account, espe-cially if the actuators are controlledby a PLC. We recommend a delaytime < 50 ms and to switch off thecorresponding contactor directly bythe limit or torque switch. Longerdelay times are possible provided

the output speed, output drive type,valve type and the type of installationare considered.

For the AUMA MATIC and AUMATICintegral controls (available for sizesSA(R) 07.1 – SA(R) 16.1) the motorwill immediately be switched off aftertripping of a switch.

Output speeds

Output speeds

With the large range of availableoutput speeds, almost everyrequired operating time can beachieved with AUMA multi-turn actu-ators.

The output speed is determined bythe motor speed and the gear reduc-tion ratios. Therefore it is necessaryto mention the output speed whenplacing an order.

For multi-turn actuators with outputdrive type A, stem nut (refer to page26), the max. permissible stemvelocity (output speed) must beobserved:

■ for gate valves max. 500 mm/ min■ for globe valves max. 250 mm/min

(max. 45 rpm)

For higher velocities or outputspeeds it is strongly recommendedto use a spring loaded stem nut, out-put drive type AF (see page 26).

Actuator controls

Which type of controls?

AUMA MATIC

The AUMA MATIC is the idealcontrol for open-close

duty. Functionssuch as the auto-matic phasecorrection sim-plifycommisioning.To operate the

actuator on site theintegral local con-trols can be used.

The following feedback signals areavailable: end positions reached,tripping torque exceeded, the selec-tor switch position and a collectivefault signal.

An explosion-proof version of theAUMA MATIC is available.

AUMATIC

The AUMATIC withmicrocontroller includesall functions of theAUMA MATIC. In addi-tion, the AUMATIC hasa variety of additionalfunctions and the equip-ment has been consid-erably expanded:

■ Non-intrusive setting(option)

■ Adaptive positioner (option)■ Programmable signal relays■ Fieldbus interface (option)

■ Display with plain text display■ Monitoring and diagnosis■ Logging of operating data■ Serial programming interface1)

The AUMATIC design: A modularsystem consisting of functions, com-munication interfaces and equip-ment elements, enables the combi-nation of the ideal solution for everyvalve automation problem.

An explosion-proof version of theAUMATIC is available.

1) Please note, due to patent law the AUMATIC product with infrared interface on local controls must not be supplied to either the UK or Japan.This product without infrared interface does not infringe a patent and can be supplied to either country.

Wall bracket

The controls, also in explosion-proofversion, can be mounted separatelyfrom the actuator on a wall bracket(see page 5). This is recommendedif:

■ limited space would restrict theaccess to directly mounted con-trols

■ high ambient temperatures in thesurroundings of the actuator couldaffect the electronics,

■ heavy vibrations of the valve couldinfluence the controls.

Actuator controls

Advantages of integral controls (option)

The aim in developing integral motorcontrols was to enable the customer

to save the high installation costs ofexternal controls. This is highlighted

by the diagram below.

External controls (A)

For actuators to be connected toexternal controls, the following mustbe considered:

■ All actuator signals, e.g. thetorque and limit switch signals,must be passed on to the externalcontrols in the control cabinet.

■ The control of the actuators via areversing contactor combinationhas to be implemented and in-stalled in the control cabinet.

■ The local controls have to be im-plemented and mounted

Integral controls (B)

Actuators with integral controls aresupplied ready for use with local con-trols and switching elements.All electrical components, e.g. limit,torque and thermoswitches, as wellas monitoring elements and possiblyavailable position transmitters areintegrated into the modern controls.This results in the following simplifiedsystems:

■ No extensive wiring in a controlcabinet is required.

■ Reliable and correct processing ofthe actuator signals assures theimmediate reaction of the controlsand prevents excesive torquesfrom building up in the valve

■ Actuator and controls are ideallyadjusted to each other

■ Standard wiring diagrams areavailable

Integral controls/Fieldbus (C)

If the actuator controls are integratedin a fieldbus system, then the instal-lation costs are further reduced. Thecommands and signals of all actua-tors (slaves) are transmitted to andfrom the master via a two-wire cableor via optical fibres. The space con-suming input/ output boards, as wellas their associate control cabinetsections, are no longer required.

Electrical connection

AUMA plug/ socket connector

Multi-turn actuators SA and SAR upto size 16.1 are equipped with AUMAplug/ socket connector for motor andcontrols. This applies whether theactuator is equipped with integralcontrols or not.

The significant advantage of thistype of connection:Once connected, the wiring remainsundisturbed, even if the actuator has

to be removed from the valve, e.g. formaintenance purposes.

For size SA 25.1 and larger the motoris connected to screw type terminalsin the terminal compartment of theactuator. The controls will still bewired to the AUMA plug/socketconnector.

Double sealed(option) The double sealed connection is a

sealed plug and socket which is fittedbetween the actuator housing andthe plug/ socket connector. Evenafter removing the plug cover or if thecable glands do not seal properly thedevice will be protected against theingress of dust or humidity.

Plug/ socket connector with terminal board for explosion-proof multi-turn actuators SAExC and SARExC

Explosion-proof actuators in ver-sions with or without controls aredesigned with a ‘flameproof enclo-sure’. The sealed terminal board ofthis electrical connection ensuresthat the flameproof enclosureremains undisturbed even if the plugcover has been removed.

The electrical connection betweenthe terminal board and the electric/electronic components within theactuator provided via a plug/ socketconnector. The advantage of themodular design with plug-in connec-

tion is thereby also provided forexplosion-proof actuators.

The customer connection compart-ment is designated protection type‘increased safety’.

By means of a protection cover,which is available as an option, thedisconnected plug may be fitted to awall to enable the operation of theplant under explosion-proof condi-tions.

Plug-in terminal connection for explosion-proof multi-turn actuators SAExC and SARExC (option)

Contrary to the plug/ socketconnector, the customer connectionis made on terminals which havebeen fitted to a terminal frame. Theconnection compartment has beenenlarged. In terms of explosion pro-tection this connection type has thesame characteristics as the plug/socket connector.

On request, these terminals can alsobe used for non-explosion-proofactuators.

By means of a protection coverwhich is available as an option, thedisconnected plug may be fitted to awall to enable the operation of theplant under explosion-proof condi-tions.

Combinations Multi-turn actuators/ Gearboxes

Combinations with bevel or spur gearboxes

By combining multi-turn actuatorsSA with spur gearboxes GST 10.1 –GST 40.1 or with bevel gearboxes GK10.2 – GK 40.2 the torque/ speedranges are considerably extended.All gearbox sizes are available withseveral reduction ratios.

Detailed information can be found onthe corresponding technical datasheets.

Combinations with worm gearboxes

Combinations with lever gearboxes

Multi-turn actuators SA can be combined with a spur or a bevel gear-box. Torques up to 16,000 Nm are possible.

In combination with a worm gearboxof the type range GS 50 – GS 500 amulti-turn actuator SA is convertedinto a part-turn actuator, usually for a90° movement. Ideal solutions areherewith available especially forlarge part-turn valves with hightorque requirements.

Multi-turn actuators up to the size40.1 can be combined with GSgearboxes. The torque range goesup to 360,000 Nm.

The worm gearboxes are available indifferent versions. Counter-clock-wise closing versions can also besupplied.


Valves which are operated via leverarrangements require a lever gear-box. Commonly a swivel movementup to 90° is performed. For suchapplications the SA multi-turn actua-tors can be combined with a levergearbox of the type range GF 50 –GF 250. The design of the GFgearboxes is based on the GS wormgearboxes.

Multi-turn actuators up to the size25.1 can be combined with GFgearboxes. The torque range goesup to 32,000 Nm.

As for the worm gearboxes, variousversions are available, e.g. for coun-ter clockwise closing.


Combinations with linear thrust units

In combination with a linear thrustunit LE, a multi-turn actuator SA isconverted into a linear actuator. Thelinear thrust unit converts the rotarymovement of the actuator outputshaft into an axial movement.Strokes up to 500 mm and thrusts upto 217 kN can be generated using aSA/LE combination.

Other information

EU Directive

Machinery Directive

According to this directive, multi-turnactuators are not completemachines. This means that a Certifi-cate of Conformity is not possible.However, AUMA confirms with theDeclaration of Incorporation (on theInternet under www.auma.com) thatduring the design stage the standardsmentioned in the Machinery Directivewere applied.

By mounting the actuator to othercomponents (valves, pipelines etc.)a ‘machine’ within the meaning of theDirective is formed. Before commis-sioning this machine a Certificate ofConformity must be issued.

Functional tests

After assembly, all actuators arethoroughly tested according toAUMA’s inspection specification andthe torque switching is calibrated.
