1. Safety instructions1.1 Range of application

AUMA actuators are designed for the operation of industrial valves,e.g. globe valves, gate valves, butterfly valves and ball valves.For other applications, please consult us. The manufacturer is not liable for

any possible damage resulting from use in other than the designated appli-cations. Such risk lies entirely with the user.Observance of these operation instructions is considered as part of the con-trols/ actuators designated use.

1.2 Electrical connectionWork performed in potentially explosive atmospheres is subject to specialregulations (national standards) which have be observed.Work at the open actuator under voltage must only be performed if it isassured that for the duration of the work there is no danger of explosion.During electrical operation, certain parts inevitably carry lethal voltages.Work on the electrical system or equipment must only be carried out by askilled electrician himself or by specially instructed personnel under the con-trol and supervision of such an electrician and in accordance with the appli-cable electrical engineering rules.

1.3 MaintenanceThe maintenance instructions (refer to page51) must be observed, other-wise a safe operation of the actuator is no longer guaranteed.

1.4 Warnings and notesFailure to observe the warnings and notes may lead to serious injuries ordamage. Qualified personnel must be thoroughly familiar with all warningsand notes in these operation instructions.Correct transport, proper storage, mounting and installation, as well as care-ful commissioning are essential to ensure a trouble-free and safe operation.During operation, the multi-turn actuator warms up and surface tempera-tures > 60 C may occur. Check the surface temperature prior to contact inorder to avoid burns.The following references draw special attention to safety-relevant proce-dures in these operation instructions. Each is marked by the appropriatepictograph.

2. Short descriptionAUMA multi-turn actuators of the type range SAExC 07.1 SAExC 16.1/ SARExC 07.1 SARExC 16.1 are driven by an electric motor and controlledby the actuator controls AUMA MATIC AMExC 01.1, which is included in thescope of delivery.

A handwheel is provided for manual operation.The limitation of travel is realised via limit switches in both end positions.Torque seating is also possible in both end positions. The type of seating isdetermined by the valve manufacturer.

Both the multi-turn actuator and the controls have a modular design, i.e.they are designed in accordance with the principle of a modular constructionsystem.This means that each actuator or each controls are individually manufac-tured and combined for a specific valve automation task. An order-specificcommission number, printed on the name plate, is assigned to each actua-tor/ controls. You can use this commission number to download the wiringdiagram, inspection records and further information from the Internet.Our website:http://www.auma.com

CommissioningPlease note that for low temperature versions ( 50 C), the controlsrequires a heat-up time.This heat-up time is applicable in case the actuator and the controls are notlive and have cooled down to ambient temperature. In case commissioninghas to be performed under these conditions, the following heat-up timeshave to be observed:

5. Transport, storage and packaging5.1 Transport . For transport to place of installation, use sturdy packaging.. Do not attach ropes or hooks to the handwheel for the purpose of lifting by

hoist.

. If multi-turn actuator is mounted on valve, attach ropes or hooks for thepurpose of lifting by hoist to valve and not to multi-turn actuator.Fitting the handwheel:For transport purposes, handwheels as from a diameter of 400 mm are sup-plied separately.

Engage manual operation prior to mounting the handwheel!If the manual operation is not engaged, damage can occur atthe change-over mechanism.. Engage manual operation (figure2):

Manually lift the red change-over lever while slightly turning the shaft backand forth until manual operation engages. The manual operation is cor-rectly engaged if the change-over lever can be lifted by approx. 85.

Manual force is sufficient for operating the change-overlever. It is not necessary to use an extension. Excessiveforce may damage the change-over mechanism.. Attach handwheel onto the red change-over lever on shaft (figure3).. Secure handwheel using the circlip supplied.

5.2 Storage . Store in well-ventilated, dry room.. Protect against floor dampness by storage on a shelf or on a wooden pallet.. Cover to protect against dust and dirt.. Apply suitable corrosion protection agent to bare surfaces.If multi-turn actuators are to be stored for a long time (more than 6 months),the following points must be observed additionally:. Prior to storage: Protect bare surfaces, in particular the output drive parts

and mounting surface, with long-term corrosion protection agent.. Check for corrosion approximately every 6 months. If first signs of corro-sion show, apply new corrosion protection.

After mounting, connect actuator immediately to electricalsystem, so that the heater prevents condensation.

5.3 PackagingOur products are protected by special packaging for the transport ex works.The packaging consists of environmentally friendly materials which can eas-ily be separated and recycled.We use the following packaging materials: wood, cardboard, paper, and PEfoil. For the disposal of the packaging material, we recommend recyclingand collection centres.

6. Mounting to valve/ gearbox. Prior to mounting the multi-turn actuator must be checked

for damage. Damaged parts must be replaced by originalspare parts.. After mounting to valve/ gearbox, touch up any possibledamage to paint finish.. Increased temperatures at valve mounting flange or valvestem:If increased temperatures > 40 C are to be expected at thevalve mounting flange or the valve stem (e.g. due to hotmedia), please consult AUMA. Temperatures > 40 C are notconsidered with regards to the non-electrical explosion protec-tion.

The multi-turn actuator leaves the factory in position CLOSED (limit switchCLOSED tripped).

. Check if mounting flange fits the valve/ gearbox.

Spigot at flanges should be loose fit!

The output drive types B1, B2, B3, or B4 (figure4) are delivered with boreand keyway (usually according to ISO 5210).

For output drive type A (figure6), the internal thread of the stem nut mustmatch the thread of the valve stem. If not ordered explicitly with thread, thestem nut is unbored or with pilot bore when delivered. For finish machiningof stem nut, refer to next page.

. Check whether bore and keyway match the input shaft of valve/ gearbox.. Thoroughly degrease mounting faces at multi-turn actuator and valve/ gearbox.. Apply a small quantity of grease to input shaft of valve/ gearbox.. Place actuator on valve/ gearbox and fasten. Fasten bolts(quality min. 8.8, refer to table1) evenly crosswise.

8. Electrical connection. When working in potentially explosive areas, observe the

European Standards EN 60079-14 Electrical Installationsin Hazardous Areas and EN 60079-17 Inspection andMaintenance of Electrical Installations in Hazardous

Areas.. Work on the electrical system or equipment must only becarried out by a skilled electrician himself or by speciallyinstructed personnel under the control and supervision ofsuch an electrician and in accordance with the applicableelectrical engineering rules.. Observe warnings at the actuator:

Wiring diagramThe wiring diagram applicable to the actuator is attached to the handwheelin a weather-proof bag, together with the operation instructions. In case thewiring diagram is not available, it can be obtained from AUMA (state com-mission no., refer to name plate) or downloaded directly from the Internet(www.auma.com).

External fuseFor short-circuit protection and for releasing the actuator, fuses and discon-nect switches have to be provided by the customer.The current values for sizing the switch can be derived from the current con-sumption of the motor plus the current consumption of the controls.Motor current consumption:Refer to name plate on motor (nominal current).Current consumption of the controls depending on the mains voltage:100 to 120 V AC = max. 650 mA208 to 240 V AC = max. 325 mA380 to 500 V AC = max. 190 mAThe maximum permissible fuse for controls with a rated power of 1.5 kW is16 A (gL/ gG), and for controls with a rated power of 7.5 kW, the valueamounts to 32 A (gL/ gG).

Cable installation in accordance with EMCSignal and bus cables are susceptible to interference.Motor cables are interference sources.. Lay cables being susceptible to interference or sources of interference at

the highest possible distance from each other.. The interference immunity of signal and bus cables increases if the cablesare laid close to the ground potential.. If possible, avoid laying long cables and make sure that they are installedin areas being subject to low interference.. Avoid long parallel paths with cables being either susceptible to interfer-ence or interference sources.. For the connection of remote position transmitters (potentiometer, RWG),screened cables must be used.

9. Manual operationThe actuator may be operated manually for purposes of setting and com-missioning and in case of motor failure or power failure.Manual operation is engaged by an internal change-over mechanism.

Engaging manual operation. Lift up change-over lever in the centre of the handwheel to approx. 85,while slightly turning the handwheel back and forth until manual operationengages (figure 18).

Manual force is sufficient for operating the change-overlever. It is not necessary to use an extension. Excessiveforce may damage the change-over mechanism.

. Release change-over lever (should snap back into initial position by springaction, figure19), if necessary, push it back manually.

Operating the change-over lever while the motor is running(figure 20) can lead to increased wear at the change-overmechanism.

. Turn handwheel into desired direction (figure21).Disengaging manual operationManual operation is automatically disengaged when motor is started again.The handwheel does not rotate during motor operation.

14. Setting the torque switching14.1 Setting . The set torque must suit the valve!. This setting must only be changed with the consent of the

valve manufacturer!

.Loosen both lock screws O at the torque dial (figure28).. Turn torque dial P to set it to the required torque (1 da Nm = 10 Nm).Example:Figure 28 shows the following setting:3.5 da Nm = 35 Nm for direction CLOSE4.5 da Nm = 45 Nm for direction OPEN. Tighten lock screws O again

. The torque switches can also be operated in manualoperation.. The torque switching acts as overload protection over fulltravel, also when stopping in the end positions by limitswitching.

14.2 Checking the torque switchesThe red test buttons T and P (figure26) are used for manual operation ofthe torque switches:

. Turning T in direction of the arrow TSC (DSR) triggers torque switchCLOSED.The red indication light (fault) on the local controls is illuminated.. Turning P in direction of the arrow TSO (DL) triggers torque switchOPEN.The red indication light (fault) on the local controls is illuminated.. If a DUO limit switching (optional) is installed in the actuator, the intermedi-ate position switches will be operated at the same time.. After checking the switches, the fault (red indication light) has to be resetusing the OPEN or CLOSE push buttons of the local controls for operationin the opposite direction.

15. Test runWork at the open actuator under voltage must only beperformed if it is assured that for the duration of the work there is no danger of explosion.

15.1 Checking the direction of rotationThis check is only necessary for mounting on wall bracket.When the AUMA MATIC controls are mounted directly to the actuator, theautomatic phase correction ensures the correct direction of rotation, even ifthe phases are crossed over during electrical installation.

. If provided, place indicator disc on shaft.The direction of rotation of the indicator disc (figure29) indicates thedirection of rotation of the output drive.. If there is no indicator disc, the direction of rotation can also be observedon the hollow shaft. For this purpose, remove screw plug (no. 27)(figure30).

. Move actuator manually to intermediate position or to sufficient distancefrom end position.. Set selector switch to local control (I) (figure31).

. Switch on the voltage supply.. Press push button CLOSE (figure32) and observe the directionof rotation:If the indicator disc turns counterclockwise, the direction of rotationis correct.

If the direction of rotation is wrong, switch off immediately.Afterwards, correct phase sequence in the connecting cable fromthe wall bracket to the actuator and repeat test run.

15.2 Checking the setting of the limit switching. Set selector switch to position OFF (0) (figure34).

The controls power supply is maintained in position OFF.

. Move actuator manually into both end positions of the valve.. Check if limit switching is set correctly for both end positions. Herebyobserve that the appropriate switch is tripped in each end position and

released again after the direction of rotation is changed. If this is not thecase, the limit switching must be set again.

When limit switching is set correctly:. Set selector switch to local control (I) (figure31).. Perform test run at the local controls via push buttons OPEN - STOP -CLOSE.

15.3 Checking the type of seatingThe valve manufacturer states whether switching off in the end positionsshould be by limit switch (limit seating) or torque switch (torque seating).. For checking the setting, refer to page33, subclause 20.2.

15.4 Checking the PTC tripping device. Turn selector switch to position TEST (wiping) (figure35).If the PTC tripping device is working properly, the tripping of the motor pro-tection is signalled via the collective fault signal (refer to wiring diagram)and via the fault indication light on the local controls.

. Turn selector switch to position RESET (wiping) (figure36):The fault signal is reset if the device is working properly.

In case the selector switch position TEST does not initiate a fault signal, thewiring and the selector switch have to be checked by the AUMA service.

If no other options (clauses 16. to 18.) require setting:. Close switch compartment (see page 31, clause 19.).26

16. Setting the potentiometer (option) For remote indication

. Move valve toend position CLOSED.. Turn potentiometer (E2) clockwise to the stop.End position CLOSED corresponds to 0 %, end position OPEN to 100 %.. Turn potentiometer (E2) slightly back.

Due to the ratio of the reduction gearings for the positiontransmitter, the complete resistance range is not alwaysutilized for the whole travel. Therefore, an external possi-bility for adjustment (setting potentiometer) must beprovided.

. Perform fine-tuning of the zero point at external setting potentiometer(for remote indication).

17.1 Setting 2-wire system 4 20 mA and 3- /4-wire system 0 20 mA

. Connect voltage to electronic position transmitter.. Move valve toend position CLOSED.. Connect ammeter for 0 20 mA to measuring points (figure39).The circuit (external load) must be connected(observe max. load R B), or the appropriate poles at the termi-nals (refer to wiring diagram) must be linked, otherwise novalue can be measured.

. Turn potentiometer (E2) clockwise to the stop.. Turn potentiometer (E2) slightly back.

. Turn potentiometer 0 clockwise until output current starts to increase.. Turn potentiometer 0 back until the following value is reached:for 3- or 4-wire system: approx. 0.1 mAfor 2-wire system: approx. 4.1 mA.This ensures that the signal remains above the dead and live zero point.. Move valve to end position OPEN.. Set potentiometer max. to end value 20 mA.. Approach end position CLOSED again and check minimum value(0.1 mA or 4.1 mA). If necessary, correct the setting.

If the maximum value cannot be reached, the selection of thereduction gearing must be checked.

Move actuator to end position OPEN.. Hold lower indicator disc CLOSED in position and turn upper disc withsymbol OPEN until it is in alignment with the mark on the cover.

Indicator disc rotates approximately 180 to 230 at full travel from OPEN toCLOSED or vice versa. For this purpose, a suitable reduction gearing wasinstalled in our works.If the turns per stroke of the actuator are changed at a later date, the reduc-tion gearing may have to be exchanged.

19. Closing the switch compartment

. Clean sealing faces of housing and cover. Check whether O-ring is in good condition.. Apply a thin film of non-acidic grease to the sealing faces.. Preserve joint surfaces with an acid-free corrosion protection agent.Flameproof enclosure! Handle cover and housing parts withcare. Joint surfaces must not be damaged or soiled in any

way. Do not jam cover during fitting.. Replace cover on switch compartment and fasten bolts evenly crosswise.Check the multi-turn actuator for damage to paint finish. Ifdamage to paint-finish has occurred after mounting, it has tobe touched up to avoid corrosion.

21.2 SettingThe positioner in the actuator controls AUMA MATIC is programmedaccording to the purchase order details and is set together with the actuatorprior to delivery.Due to peculiarities of the regulating system not known beforehand, a readjustment may become necessary. Before adjusting the positioner, the pro-gramming of the positioner should be checked.

. Check programming of the logic board according to subclause20.2.

The self-retaining REMOTE function (see table 4) must be

switched off in conjunction with the positioner.. Take off cover plate (figure47) and carry out required programming atpositioner board (figure48) according to tables6 and 7.

Prior to setting, it must be ensured that the circuit for theposition feedback E2 (see wiring diagram) is closed(measuring device or link). In case of missing signal E2, theLED (V10) E1/E2 < 4 mA (figure47) is illuminated and thepositioner shows no reaction.

21.4 Positioner adjustment for end position OPEN (standard version)

. Run multi-turn actuator by pressing push button (local controls) toendposition OPEN.. Connect voltmeter to measuring points MP2 and MP1 for measuring theactual value E2:When position feedback is set correctly, the voltmeter shows 5 V.If measured value is not correct:Adjust position feedback according to clause16. and 17. and repeatpositioner adjustment.. Connect max. command signal (nominal value E1) = 20 mA.. Connect voltmeter to measuring points MP4 and MP3 for measuring thenominal value E1:For a nominal value of 20 mA, the voltmeter shows 5 V.If measured value is not 5 V:Check the externally supplied command signal E1.

21.5 Setting the sensitivity . Set selector switch at the local controls to position REMOTE.. Set command signal E1 according to label on cover plate (see figure50).The sensitivity (D E / dead band) is set to maximum value (2.5 %) in thefactory.. The deadband can be increased by turning the potentiometer D E (P9)clockwise. Left stop = small dead band (= high sensitivity). For a precisesetting of the dead band, a set point device with setting options in the 0.1mA range is required.. A better sensitivity (D Emin= 0.25 %) can be achieved by turning the potenti-ometer P7 (sens) clockwise.

When setting D E, the following must be observed:If the number of starts is too high, this will lead to unneces-sary wear at the valve and actuator. Therefore the maximumpossible dead band acceptable for the process must be set.

To prevent exceeding the max. permissible number of starts (refer to Techni-cal data sheets for modulating actuators) in extreme cases, a pause timebetween 0.5 s (left stop) and 10s (right stop) may be set with the potentio-meter t-off (P10).

21.6 Positioner adjustment for end position OPEN (inverse operation)

In standard version the maximum input signal (E1 = 20 mA) results in opera-tion to end position OPEN.. By switching the code switch S3-7 (figure52) to position 1, an inversion

of this signal definition (inverse operation) can be achieved.. In case an RWG (option) is installed, the connections 7 (red) and 5 (black)on the positioner board (figure38) of the actuator have to be exchanged.. In case a potentiometer is installed, (option) the connections 21 (red) and22 (black) at the potentiometer must be interchanged.

Before beginning the setting of the positioner, it has to beensured that the limit and torque switching of the actuatoras well as the feedback have been set (clauses 16. and 17.).

. Set selector switch (local controls) to position LOCAL.. Run actuator with push button toend position OPEN .. Supply nominal value E1 of 0 or 4 mA (see wiring diagram).

. Turn potentiometer t-off (P10) counterclockwise to the stop(figure52).

Missing signals E1/ E2 or wrong polarity are indicated byLED (V10) E1/E2 < 4 mA" (figures50 or 52)

. Connect voltmeter to measuring points MP3 and MP4 (figure52) for mea-suring the nominal value (0 5 V).For a nominal value E1 of 0 mA, the voltmeter shows 0 V.For a nominal value E1 of 4 mA, the voltmeter shows 1 V.In case nominal value (0 V or 1 V) is not correct:Correct nominal value signal in control room.. Connect voltmeter to measuring points MP2 and MP1 for measuring theactual value signal.For an actual value E2 of 0 mA, the voltmeter shows 0 V.For an actual value E2 of 4 mA, the voltmeter shows 1 V.Adjust position feedback according to clause16. and 17. and repeatpositioner adjustment.

21.8 Positioner in Split Range version (option)

For Split Range, a modified version of the positioner is used. The standardversion is not suitable for Split Range operation.Split Range operation is only possible with the position transmitter RWG.

21.8.1 Split Range: description of functions

In Split Range operation, a setpoint is shared by up to four positioners. Atypical example is a pipeline with a bypass. The actuator mounted on thebypass reacts in the lower range (0 10 mA), the actuator on the mainvalve in the upper range (10 20 mA). Other values such as 4 12 mA and12 20 mA can also be set.

21.8.2 ProgrammingDIP 5 at code switch S1-7 must always be in position ON for Split Range

version.

The further programming of the positioner via the code switches S2-7 andS3-7 can be made in the same way as during normal operation.

21.8.3 Positioner adjustment for Split Range (see also example further down the page)

. Supply the specified minimum command signal (nominal value E1) for thepositioner and check by measuring with voltmeter at the measuring pointsMP3 and MP4 (figure53).. Connect voltmeter between measuring point M3 and measuring point MP1.Calculate setting value:Initial value = E 1min [in Ampere] x 250 OhmSet initial value with potentiometer P5.. Supply specified maximum command signal (nominal value E1) and checkby measuring at the measuring points MP3 and MP4.. Connect voltmeter between measuring point M9 and measuring point MP1.Set potentiometer P6 to 5 V.. Supply input signal E1 from minimum to maximum value and check the setrange 0 5 V at measuring point M9. If necessary, readjust with P5 or P6.. Apply the same procedure to the second actuators positioner and setaccording to the specified nominal values E1.. After setting the Split Range operation, perform further readjustment asdescribed on page 38.

Example:Two actuators are to be operated in Split Range version. Actuator 1 must bein position CLOSED with a nominal value signal E1 of 0 mA and in positionOPEN with a signal of 10 mA.Actuator 2 must be in position CLOSED with a nominal value signal of10 mA and in position OPEN with a signal of 20 mA.

. Positioner actuator 1:Supply E1 = 0 mA, set with P5 = 0 V at M3 (measured against MP1),supply E1 = 10 mA, set with P6 = 5V at M9 (measured against MP1).. Positioner actuator 2:Supply E1 = 10 mA, set with P5 = 0 V at M3 (measured against MP1),supply E1 = 20 mA, set with P6 = 5V at M9 (measured against MP1).. Perform adjustments and settings for E2, etc. Afterwards the nominalvalue E1 can be transmitted through both actuators (connected in series).When operating within range E1 = 0 10 mA, actuator 1 moves, actuator2 remains in end position CLOSED. When operating within rangeE1 = 10 20 mA, actuator 2 moves, actuator 1 remains in end positionOPEN.
