Electric actuators are among themost important components of thesafety system of a nuclear powerplant. This means that the actuatorshave to operate the valve correctlyunder defined conditions, e.g. toremain safely operable even underDBE conditions.

For more than 20 years AUMA hasmanufactured electric actuators foruse in nuclear power plants. Duringthis time AUMA has acquired aknow-how in this field that can hardlybe surpassed. AUMA is one of theleading electric actuator manufactur-ers world-wide.

AUMA has two multi-turn actuatorranges SAN/ SARN and SAI that arequalified for the use in nuclear powerplants. The SAI actuators areapproved for the use ‘inside Contain-ment’, the SAN/ SARN actuators arequalified for ‘outside Containment’.With this brochure AUMA offers acomplete overview of construction,functions and equipment of the SAN/SARN actuator range. The SAI actu-ators are described in a separatebrochure.

Applications

AUMA actutators of the type SANand SARN are qualified for the useoutside containment. This corre-sponds to the yellow section in theillustration. They are used whereverthe automation of a valve requiresrotation. The adaption to the require-ments of nearly every valve automa-tion task is possible. This is achievedby:

■ various combination possibilitieswith AUMA valve gearboxeswhich are also qualified for the usein nuclear power plants. Therebythe torque range can be furtherextended and/ or the multi-turn ac-tuator can be converted into apart-turn or linear actuator

■ a large variety of versions. Whet-her for open loop or closed loopcontrol with a large variety of op-tions, a suitable version is availa-ble for every requirement.

Open-close duty

A type code defines the various ver-sions.

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.

Type of duty for multi-turn actua-tors for open-close duty (SAN)

AUMA multi-turn actuators SAN foropen-close duty are rated forshort-time duty S2 - 15 min. Descrip-tion of types of duty on page 7.

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.

Short-time duty S2

The operation time at a constant load is short, so that ther-mal equilibrium is not reached. The pause is long enoughfor the machine to cool down to ambient temperature. Theduration of the short-time operation is limited to 15 min.

Intermittent duty S4

The duty is a sequence of identical cycles which consist ofstarting time, operation time with constant load and restperiod. The rest period allows the machine to cool down sothat thermal equilibrium is not reached. The relative on-time at S4 - 25 % is limited to 25 %.

Functions

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 8), 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.

Equipment/ 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, except for actuators withvariable speed motors. Therefore itis necessary to mention the outputspeed when placing an order.

For multi-turn actuators with outputdrive type A, stem nut (refer to page

17), 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 17).

side and are switched using a common control element.1 NC and 1 NO

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 page10) 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.

Combinations with spur gearboxes GSTN

Multi-turn actuators SAN can becombined with a spur gearbox.Torques up to 16,000 Nm are possi-ble.

By combining the multi-turn actua-tors SAN with the spur gearboxesGSTN 25.1 – GSTN 40.1 the torque /output speed ranges can be consider-ably increased. All gearbox sizes areavailable with several reduction ratios.

Detailed information can be found onthe corresponding technical datasheets.

The position of the valve can betransmitted as a continuous signal:

■ for remote indication■ as feedback signal to a positio-

ner

For continuous transmission of thevalve position a reduction gearing isrequired in the control unit of theactuator.

Position feedback is provided as ananalogue feedback signal by a pre-cision potentiometer

Design principle

MotorAn especially high starting torque isfrequently required to unseat valves

from the end position. The 3-phase ACmotors developed by AUMA fulfil this basicrequirement.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 14.

GearingThe well proven principle of wormgearing is used to reduce the motor

speed 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.

1

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 or the torque required atthe output drive, respectively.

The switches signal to the actuator controlsthat the set tripping points have beenreached, which then switches off the motor.

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.

Further information on page 17.

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 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.

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.

Motor protection 3 Thermoswitches1) Within this range, the actuator reaches the specified torque. Overvoltage may result in excessive temperature rise in the motor windings. The

stall torque increases in the ratio of the square of overvoltage divided by the standard voltage. In the case of undervoltage the motor torque(stall torque) decreases in the ratio of the square of undervoltage divided by the standard voltage. Larger voltage variations have therefore tobe considered when sizing the actuator.

In order to protect the motor againstoverheating thermoswitches areembedded in the motor windings.When integrated into the control cir-cuit, they will protect the motoragainst damage due to excessivelyhigh winding temperature.

Thermoswitches offer better protec-tion than thermal overload relays,since the temperature rise is directlymeasured at the motor.

The thermoswitches will interrupt thecontrol circuit as soon as a windingtemperature of 155° 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.

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 providedthe output speed, output drive type,valve type and the type of installationare taken into consideration.

The lifetime in operation hours (h)depends on the load and the numberof starts. A high starting frequencywill rarely improve the modulatingaccuracy. To reach the longest pos-sible maintenance and fault-free

operation time, the number of startsper hour should be chosen as low aspermissible for the process. This canbe achieved by setting the modulat-ing parameters accordingly.

Other information

EU Directives

Machinery Directive

According to this directive, AUMAactuators 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.

A final inspection record is alwaysissued. The inspection records canbe retrieved online via the Internet(www.auma.com).
