Multi-turn actuators with integral controls

Controls are required to operate anactuator and to process actuator sig-nals. In general it is possible to installthe controls externally in a controlcabinet.

An actuator with integral controls isoften the better solution. Labourintensive design and installationcosts are considerably reduced andan optimum functionality for theapplication are just a few of the manyadvantages. AUMA offers nearly alltypes of actuators with integral con-trols.

AUMA actuator controls are avail-able with a wide variety of equipment- from the simple OPEN - CLOSEcontrol to the microcontroller versionwith logging of operating data or aversion with a fieldbus interface.

Type designation

A type code defines the various ver-sions.

It must be noted that not every com-bination is possible, e.g. an explo-sion-proof version of SARV is notavailable.

Open-close duty

Open-close duty The normal valve positions inopen-close duty are the end posi-tions OPEN and CLOSED. Afterreceiving an appropriate commandthe actuator operates the valve toone of the two end positions or, ifnecessary, to a pre-defined interme-diate position.

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

Type of duty for multi-turn actua-tors for open-close service

AUMA multi-turn actuators SA foropen-close service are rated forshort time duty S2 - 15 min. A specialversion for S2 - 30 min is also avail-able but necessitates reducedtorques.

Functions

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 requirements applyto the multi-turn actuators for thisduty. Mechanical components andthe motor must be designed appro-priately to withstand a large numberof operations without affecting therequired modulating accuracy.

Functions

Comparison short-time and intermittent duty

Short-time duty Intermittent duty

Type of duty according toIEC 34-1

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 short-time duty is limited to 15 minor 30 min.

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%respectively 50%.

S5

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

Functions

Limit switching

The limit switching enables to switchoff the actuator when reaching thedefined valve position, usually anend position. It is part of the controlunit (refer to page 14).

The travel is measured by twomechanical counter gear mecha-nisms, which when reaching the setswitching points operate the electri-cal limit switch via cams.

The torque switching enables toswitch off the actuator when reach-ing a pre-defined torque instead of adefinite position. The tripping torquecan be set independently for eachdirection.

The range of tripping torques for thevarious actuator sizes are listed onpage 11.

Torque seating in the endpositions

For tight closing certain valve typesmust be operated into the end posi-tion CLOSED with a defined force.Such valves can be closed reliablyby torque seating.

Limit seating is common in the endposition OPEN.

Torque switching as overloadprotection

The torque switching acts as over-load protection over full travel, alsowhen limit seating in the end posi-tions. Sluggishness of the valve or atrapped object in the pipeline mayrequire an excessive, non-justifiedtorque, which may damage thevalve. This is prevented by thetorque switching.

Limit switching at torque seating

When torque seating in the end posi-tion the limit switching serves forsignalisation. Therefore the actuatorcontrols can differentiate whetherthe actuator was switched off thenormal way in the end position or thetorque switching was activated inmid travel position due to excessivetorque, which will cause a fault signalin the control room.

The setting accuracy is 1/10 turn andthe tripping point repetitive errorgoes towards zero. Any possiblecoasting of the motor and gearing isnot considered.

Following numbers of turns perstroke are possible:

l 1 - 500l 1 - 5000 (Option).

DUO (Four train gear) limit switching

With the DUO limit switching an addi-tional switching point can be set foreach direction of rotation (intermedi-ate position switches).The switchingcan be set to any valve positionbetween the end positions. Theswitch remains tripped from theadjusted tripping point up to the endposition, if not more than 120 rota-tions of the hollow shaft are between.

The switch signal can be used e.g.to:

l signalize a certain valve position,l to start an additional actuator

which is mounted on a bypassvalve,

l to start or switch off any unit, e.g. apump.

Analogue torque sensing (option)

If the actuator is equipped with ananalogue torque sensing, thedemanded torque can be constantlydisplayed. The torque signal is avail-able as 4 - 20 mA current signal.

The maximum values 4 mA and20 mA can only be reached when thetorque switching is set to the maxi-mum possible tripping torque.

Running indication

The blinker switch is part of the stan-dard equipment of the actuator typesSA and can be used for running indi-cation. The contacts are wired to theAUMA plug/ socket connector.

Equipment

Switches

With the help of the switches, themechanically measured valuestravel (i.e. number of turns) andtorque are converted into usable sig-nals for the actuator controls. Theswitches are integrated into the con-trol unit which contains four switchesin the basic version:

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

l one torque switch each for thedirections 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 with aDUO-limit switching (refer to page10) two more limit switches are avail-able.

To meet the high demands regardingreliability, AUMA uses speciallydeveloped high quality microswitcheswith snap action mechanism.

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.

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-phaseAC-motors, 1-phase AC- and DC-motors areavailable for the actuator sizes up to 14.5resp. 16.1. The sizes SA 07.1 up to SA 10.1are available with variable speed motor.

The standard motors are connected via aninternal plug/ socket connector (up to 16 Anominal current) to the customer’s plug. Thisenables quick exchange of the motor, e.g. forchange of output speed.

Further information on page 16.

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 torque switch-ing) are provided within the control unit. Theymeasure the travel resp. the torquedemanded at the output drive.

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

GearingThe well proved principle of wormgearing, sometimes combined with a

planetary gear, is used to reduce the motorspeed to the required actuator output speed.Self-locking is achieved by the worm gear-ing. Worm shaft and output shaft with theworm wheel run in ample sized bearings.

The sliding worm is positioned between twosets of springs on the worm shaft. The wormwill be moved in relation to the torque. Thisaxial displacement, as measure for thetorque, is transmitted to the control unit vialever and gear wheels.

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

Valve attachmentThe mounting flange is according toDIN EN ISO 5210 resp. DIN 3210.

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

Design principle

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, easy changeover to manual drive is possible even if theactuator has been operated at full ratedtorque.

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

Electrical connectionThe connections for motor andcontrols 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.

In case the plug/ socket is disconnected formaintenance work, the control wiringremains undisturbed.

For explosion-proof types SAEx and SARExplug/ socket connectors are not permitted. Inthis case terminals are used for the electricalconnection.

Equipment

Motors

3-phase AC motors

As a standard, AUMA multi-turnactuators are equipped with 3-phaseAC motors (TENV, pot-type motorwithout ventilation).

1-phase AC motors

AUMA multi-turn actuators SA 07.1 –SA 14.5 can be supplied as an optionwith 1-phase AC motor. The requiredcapacitor and the sometimes neces-sary starting switch are fitted in anenlarged plug cover.Note: For availabe sizes and speedsplease refer to separate data sheet.

DC motors

AUMA multi-turn actuators are alsoavailable with DC motors.

Note: In some cases starting resis-tors may be required (refer to sepa-rate data sheet). Those are not partof the AUMA supply.

Variable speed motor

The sizes 07.1 – 10.1 are availablewith electronically commutatedmotors (SARV). For actuators withthese motors the output speed canbe adjusted via the actuator controlsVARIOMATIC. Therefore therequired operating time can be set atsite. Furthermore the actuators havethe following advantages:

l Motor braking(S5 - 40 % operation)

l short braking time < 5 msl 1-phase supply voltage

Special motors

On request and if for technical rea-sons possible, two-speed motors orbrake motors can be used.

Motor protection

In order to protect the motor againstoverheating, thermoswitches resp.PTC thermistors are embedded inthe windings of the 3-phase AC and1-phase AC motors. When inte-grated into the control circuit, theywill protect the motor against dam-age due to excessively high windingtemperature.

Thermoswitches resp. PTC thermis-tors offer a better protection thanthermal overload relays, since thetemperature rise is directly mea-sured at the 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 actuatorcan be switched on again.

Important! The motor protectiondevices (thermoswitches or thermis-tors) have to be integrated into thecontrols, otherwise the warranty forthe motor will lapse.

If the multi-turn actuator is equippedwith integral controls, the thermo-switches are always integrated.

Output speeds

Output speeds

With the large range of available out-put speeds, almost every requiredoperating time can be achieved withAUMA multi-turn actuators.

The actuator output speed is deter-mined by the motor speed and thegear reduction ratios, except foractuators with variable speed motorsTherefore it is necessary to mentionthe output speed when placing anorder.

For multi-turn actuators with outputdrive type A, stem nut (refer to page22), the max. permissible stemvelocity (output speed) must beobserved:

l for gate valves max. 500 mm/ minl 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 (refer to page 22).

Self-locking

AUMA multi-turn actuators SA 07.1 –SA 16.1 are self-locking1) withexception of the output speeds 125and 180 rpm. Actuators of the sizesSA 35.1 and SA 40.1 with the outputspeed 32 rpm are not self-locking.This is additionally the case forSA 35.1 with an output speed of45 rpm. These non self-lockingmulti-turn actuators have a doublestart worm / worm wheel. After thetorque switch has tripped, the slidingworm will be able to move back to itsinitial position by action of the torquemeasuring springs. This allows the

torque switch to be released. If thecontrol system provides continuoussignals, this will result in a constantswitching on and off of the motor(Pumping effect).

Remedy:

l for SA 07.1 to SA 16.1 using motorcontrols AUMA MATIC, or

l ‘capturing’ the off signal with anauxiliary contactor or relay.

1) self-locking under normal operation con-ditions; a self-locking gearing does notensure a safe stopping after an opera-tion. If this is required, a brake motormust be used.

Equipment

Heater

Condensation in the actuator is pos-sible due to wide fluctuation of theambient temperature. The heaterintegrated in the control unit preventsthis in general.

The heater is rated for continuousduty. Therefore it should always beenergized, but at least when theactuator is not operating.

Integral controls (option)

The aim in developing integral motorcontrols was to enable the customer

to save the high installation costs forexternal controls. The diagram

shows this impressively.

External controls (A)

For connecting actuators to externalcontrols, the following must be con-sidered:

l Space in a control cabinet must beprovided.

l For each actuator a power switch-ing device, e.g. reversingcontactors, must be installed.

l A supply cable must be connectedfrom each switching device to theappropriate actuator.

l Controls must be provided to pro-cess the actuator signals andoperate the switching deviceaccordingly.

l Extensive wiring diagrams mustbe prepared

l All actuator signals, e.g. thetorque and limit switch signals,must be passed on to the controls.For this purpose a multi-core con-trol cable is neccessary.

l If local controls are required, theymust be installed and need addi-tional separate wiring.

Integral controls (B)

Actuators with integral controlsinclude control and switching ele-ments and are supplied ready foruse.All electrical components, e.g. limit,torque and thermo switches, as wellas monitoring elements and positiontransmitter (option) are intregratedinto the modern controls. This resultsin the following simplifications:

l No extensive wiring in the externalcontrol cabinet is required.

l Several actuators can be con-nected to a common supply cable,using an isolating switch for eachactuator.

l the motor protection is integratedinto the controls.

l The actuator signals are pro-cessed in the controls, only feed-back to the process control sys-tem is necessary.

Integral controls / fieldbus (C)

If the actuator controls are integratedin a fieldbus system, the installationcosts are further reduced. The com-mands and signals of all actuatorsare transmitted to and from the mas-ter station via a two-wire cable or afibre-optical cable (option).The space consuming input/outputboards, as well as their associatecontrol cabinet sections, are no lon-ger required.

The function of multi-turn actuatorsAUMA NORM is not affected byvibrations up to 0,75 g in a frequencyrange of 5 Hz to 200 Hz.

EU-Directives

Machinery Directive

According to this directive, actuatorsare no complete machines. Thismeans that a Declaration of Confor-mity is not possible. However, AUMAconfirms with the Declaration ofIncorporation (available online in theinternet at: www.auma.com (down-load section)) that during the designstage the standards mentioned inthe Machinery Directive wereapplied.

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

Low Voltage and ElectromagneticCompatibility (EMC) Directives

AUMA actuators fulfil the require-ments, which was proved in exten-sive tests. Therefore AUMA issued aCertificate of Conformity (availableonline in the internet at:www.auma.com (download sec-tion)) according to these Directives.

CE-Mark

Since AUMA actuatorsfulfil the requirements ofthe Low Voltage and EMC

Directives, the actuators are markedwith the CE-mark in accordance withthe directives.

Functional tests

After assembly all actuators are thor-oughly tested and the torque switch-ing calibrated according to AUMA’sinspection specification.

A final inspection record can be pro-vided. This inspection records arealso available in the internet at:www.auma.com (services section).
