1. Safety instructions
1.1 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 applications. Such risk lies entirely with the
user.
Observance of these operation instructions is considered as part of the actuator’s
designated use.
1.2 Commissioning
(electrical connection)
During electrical operation, certain parts inevitably carry lethal voltages. Work on
the electrical system or equipment must only be carried out by a skilled electrician
themselves or by specially instructed personnel under the control and supervision
of such an electrician and in accordance with the applicable electrical engineering
rules.
1.3 Maintenance The maintenance instructions (refer to page 25) must be observed, otherwise a
safe operation of the actuator is no longer guaranteed.
1.4 Warnings and notes Non-observance of the warnings and notes may lead to serious injuries or
damage. Qualified personnel must be thoroughly familiar with all warnings and
notes in these operation instructions.
Correct transport, proper storage, mounting, and installation, as well as careful
commissioning are essential to ensure a trouble-free and safe operation.
During operation, the multi-turn actuator warms up and surface temperatures
> 140 °F may occur. Check the surface temperature prior to contact in order to
avoid burns.
The following references draw special attention to safety-relevant procedures in
these operation instructions. Each is marked by the appropriate pictograph.

2) For 3-phase asynchronous motors in enclosure protection IP 68, higher corrosion protection KS or KX is strongly recommended. Additionally, for enclosure
protection IP 68, we recommend to use the double sealed terminal compartment DS.
For 1-phase AC motors, DC motors, or special motors, the enclosure protection according the name plate applies.
3) Versions with RWG up to max. to + 158 °F
4) The lifetime depends on the load and the number of starts. A high starting frequency will rarely improve the modulating accuracy. To reach the longest possible
maintenance and fault-free operation time, the number of starts per hour chosen should be as low as permissible for the process.

4. Transport, storage and packaging
4.1 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 the purpose
of lifting by hoist to valve and not to multi-turn actuator.
Fitting the handwheel: For transport purposes, handwheels from a diameter of 400 mm (1 inch
corresponds to 25.4 mm) are supplied separately.
Engage manual operation prior to mounting the handwheel! If the
manual operation is not engaged, damages can occur at the
change-over mechanism.
.Engage manual operation (figure A-1):
Manually lift the red change-over lever while slightly turning the shaft back and
forth until manual operation engages. The manual operation is correctly engaged
if the change-over lever can be lifted by approx. 85°.
Manual force is sufficient for operating the change-over lever. It is
not necessary to use an extension. Excessive force may damage
the change-over mechanism.
.Install the hand wheel over the red change-over lever on to the shaft (figure A-2).
.Secure handwheel using the snapring supplied.
4.2 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 uncoated surfaces.
If multi-turn actuators are to be stored for a long time (more than 6 months), in
addition, the following points must imperatively be observed :
.Prior to storage: Protect uncoated 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 corrosion
show, apply new corrosion protection.
After mounting, connect actuator immediately to electrical system,
so that the heater prevents condensation.
4.3 Packaging Our products are protected by special packaging for the transport ex works. The
packaging consists of environmentally friendly materials which can easily be
separated and recycled.

Figure A-1 Figure A-2

We use the following packaging materials: wood, cardboard, paper and
Polyurethane foam. For the disposal of the packaging material, we recommend
recycling and collection centers.
5. Mounting to valve/gearbox .Prior to mounting the multi-turn actuator must be checked for
damage. Damaged parts must be replaced by original spare
parts.
.After mounting, check multi-turn actuator for damage to paint
finish. If damage to paint-finish has occurred after mounting, it
has to be touched up to avoid corrosion.
Mounting is most easily done with the valve shaft/gearbox shaft pointing vertically
upward. But mounting is also possible in any other position.
The multi-turn actuator leaves the factory in position CLOSED (limit switch
CLOSED 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 (figure A-3) are delivered with bore and
keyway (usually according to ISO 5210) and are sometimes shipped with bore and
keyway according to customer request.
For output drive type A (figure B-1), the internal thread of the stem nut must match
the thread of the valve stem. If not ordered explicitly with thread, the stem nut is
unbored or with pilot bore when delivered. For finish machining of 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 grade 5, refer
to table 2) evenly crosswise.

6. Manual operation The actuator may be operated manually for purposes of setting and
commissioning, 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 center of the handwheel to approx. 85°, while
slightly turning the handwheel back and forth until manual operation engages
(figure C).
Manual force is sufficient for operating the change-over lever. It is
not necessary to use an extension. Excessive force may damage
the change-over mechanism.
.Release change-over lever (should snap back into initial position by spring
action, figure D), if necessary, push it back manually.
Operating the change-over lever while the motor is running
(figure E) can lead to increased wear at the change-over
mechanism.
.Turn handwheel in desired direction (figure F).
Disengaging manual operation:
Manual operation is automatically disengaged when the motor is started again.
The handwheel does not rotate during motor operation.

7.2 Motor connection for the sizes SA(R) 25.1/SAR 30.1 – SA 48.1.
From the size SA(R) 25.1, the power for the motor is connected to separate
terminals. For this, the cover at the motor connection compartment has to be
removed.
The control contacts are connected to the AUMA plug/socket connector.
Cross section motor terminals:
16 mm² to 70 mm² (6 to 2/0 AWG), depending on the actuator size
7.3 Motor connection for
special motors
For versions with special motors (e.g. DC motors), the connection is
performed directly at the motor (figure G-4).
7.4 Delay time The delay time is the time from the tripping of the limit or torque switches to the
motor power being removed. To protect the valve and the actuator, we recommend
a delay time < 50 ms. Longer delay times are possible provided the output speed,
output drive type, valve type, and the type of installation are taken into
consideration.
We recommend to switch off the corresponding contactor directly by the limit or
torque switch.
7.5 Controls made by AUMA In case the required reversing contactors are not to be installed in the control
cabinet, the controls AUMA MATIC or AUMATIC for the sizes SA(R) 07.1 – SA(R)
16.1 can be easily mounted to the actuator at a later date.
For enquiries and more information, please state our commission no. (refer to
actuator name plate).
7.6 Heater AUMA multi-turn actuators have a heater installed as standard. To prevent
condensation, the heater must be connected.
7.7 Motor protection In order to protect against overheating and extreme high temperatures at the
actuator, PTC thermistors or thermoswitches are embedded in the motor winding.
The thermoswitch is tripped as soon as the max. permissible winding temperature
has been reached.
Failure to integrate PTC thermistors or thermoswitches into the control circuit voids
the warranty for the motor.
7.8 Remote position transmitter For the connection of remote position transmitters (potentiometer, RWG) shielded
cables must be used.

7.9 Limit and torque switches
Only the same potential can be switched on the two circuits (NC/NO contact) of a
limit or torque switch. If different potentials are to be switched simultaneously,
tandem switches are required.
To ensure correct actuator indications, the leading contacts of the tandem switches
must be used for that purpose and the lagging contacts for motor switching off.
7.10 Fitting of the cover After connection:
.Insert the socket carrier (51.0) into the plug cover (50.0) and fasten it with
screws (51.01).
.Clean sealing faces at the plug cover and the housing.
.Check whether O-ring is in good condition.
.Apply a thin film of non-acidic grease (e.g. Vaseline) to the sealing faces.
.Replace plug cover (50.0) and fasten bolts (50.01) evenly crosswise.
.Fasten conduit connections with the specified torque to ensure the required
enclosure protection.

.Turn handwheel clockwise until valve is closed.
.After having reached the end position, turn back handwheel by approximately ½
a turn (overrun). During test run, check overrun and, if necessary, correct setting
of the limit switching.
.Press down and turn setting spindle A (figure K-1) with a flat blade
screw driver in direction of arrow, thereby observe pointer B.
While a ratchet is felt and heard, the pointer B moves 90° every time.
When pointer B is 90° from mark C, continue turning slowly. When pointer B has
reached the mark C, stop turning and release setting spindle. If you override the
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
9.2 Setting the end position OPEN (white section)
.Turn handwheel counterclockwise until valve is open, then turn back by
approximately ½ a turn.
.Press down and turn setting spindle D (figure K-1) with a flat blade screw driver
in direction of arrow, thereby observe pointer E.
While a ratchet is felt and heard, the pointer E moves 90° every time.
When pointer E is 90° from mark F, continue turning slowly. When pointer E has
reached the mark F, stop turning and release setting spindle. If you override the
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
9.3 Checking the limit switches The red test buttons T and P (figure K-1) are used for manual operation of the limit
switches.
.Turning T in direction of the arrow LSC (WSR) triggers limit switch CLOSED.
.Turning P in direction of the arrow LSO (WÖL) triggers limit switch OPEN.

10. Setting the DUO limit switching (option)
Any application can be switched on or off via the two intermediate position
switches.
For setting, the switching point (intermediate position) must be
approached from the same direction as later during
electrical operation.
10.1 Setting the direction CLOSE (black section)
.Move valve to desired intermediate position.
.Press down and turn setting spindle G (figure K-2) with a flat blade
screw driver in direction of arrow, thereby observe pointer H.
While a ratchet is felt and heard, the pointer H moves 90° every time.
When pointer H is 90° from mark C, continue turning slowly. When pointer H has
reached the mark C, stop turning and release setting spindle. If you override the
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
10.2 Setting the direction OPEN (white section)
.Move valve to desired intermediate position.
.Press down and turn setting spindle K (figure K-2) with a flat blade
screw driver in direction of arrow, thereby observe pointer L.
While a ratchet is felt and heard, the pointer L moves 90° every time.
When pointer L is 90° from mark F, continue turning slowly. When pointer L has
reached the mark F, stop turning and release setting spindle. If you override the
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
10.3 Checking the DUO switches The red test buttons T and P (Figure K-2) are used for manual operation of DUO
limit switches.
.Turning T in direction of the arrow TSC (DSR) triggers DUO limit switch CLOSED. The
torque switch CLOSED is actuated at the same time.
.Turning P in direction of the arrow TSO (DÖL) triggers DUO limit switch OPEN. The
torque switch OPEN is actuated at the same time.

11. Setting the torque switching
11.1 Setting .The set torque must suit the valve!
.This setting should only be changed with the consent of the
valve manufacturer!
Setting CLOSED Setting OPEN
.Loosen both lock screws O at the torque dial (figure L).
.Turn torque dial P to set it to the required torque.
Examples:
Figure L shows the following setting:
35 ft lbs for direction CLOSE
25 ft lbs for direction OPEN
.Tighten lock screws O again
.The torque switches can also be operated in manual
operation.
.The torque switching acts as overload protection over full travel,
also when stopping in the end positions by limit switching.
11.2 Checking the torque switches
The red test buttons T and P (figure K-2) are used for manual operation of the
torque switches:
.Turning T in direction of the arrow TSC (DSR) triggers torque switch CLOSED.
.Turning P in direction of the arrow TSO (DÖL) triggers torque switch OPEN.
.If a DUO limit switching (optional) is installed in the actuator, the intermediate
position switches will be operated at the same time.

12. Test run
12.1 Check direction of rotation .If provided, place indicator disc on shaft.
The direction of rotation of the indicator disc (figure M-1) indicates the direction
of rotation of the output drive.
.If there is no indicator disc, the direction of rotation can also be observed on the
hollow shaft. For this, remove screw plug (no. 27) (figure M-2).
.Move actuator manually to intermediate position or to sufficient distance from
end position.
.Switch on actuator in direction CLOSE and observe the direction of rotation:
If the direction of rotation is wrong, switch off immediately
Then, correct phase sequence at motor connection. Repeat test run.
12.2 Check limit switching .Move actuator manually into both end positions of the valve.
.Check if limit switching is set correctly. Hereby observe that the appropriate
switch is tripped in each end position and released again after the direction of
rotation is changed. If this is not the case, the limit switching must first be set, as
described from page 15.
If no other options (sections 13. to 15.) require setting:
.Close switch compartment (see page 23, section 16.).

13. Setting the potentiometer (option)
– For remote indication –
.Move valve to end position CLOSED.
.If installed, pull off indicator disc.
.Turn potentiometer (E2) clockwise until stop is felt.
End position CLOSED corresponds to 0 %, end position OPEN to 100 %.
.Turn potentiometer (E2) back a little.
Due to the ratio of the reduction gearings for the position
transmitter the complete resistance range is not always utilized for
the whole travel. Therefore, an external possibility for adjustment
(setting potentiometer) must be provided.
.Perform fine-tuning of the zero point at external setting potentiometer (for remote
indication).
