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 appli-
cations. Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the con-
trols’/actuator’s designated use.
1.2 Electrical connection
Work performed in potentially explosive atmospheres is subject to special
regulations (national standards) which have be observed.
Work at the open actuator under voltage must only be performed if it is
assured 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 a
skilled 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 Maintenance
The maintenance instructions (refer to page 50) must be observed, other-
wise a safe operation of the actuator is no longer guaranteed.
1.4 Warnings and notes
Failure to observe 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 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 in
order to avoid burns.
The following references draw special attention to safety-relevant proce-
dures in these operation instructions. Each is marked by the appropriate
pictograph.
This pictograph means: Note!
“Note” marks activities or procedures which have major influence on the cor-
rect operation. Non-observance of these notes may lead to consequential
damage.

with actuator controls AUMA MATIC AMExC 01.1 Operation instructions

2. Short description
AUMA 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 controlled by the actuator controls AUMA
MATIC AMExC 01.1, which is included in the scope 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 is
determined 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 construction
system.
This means that each actuator or each controls are individually manufac-
tured and combined for a specific valve automation task. An order-specific
commission number, printed on the name plate, is assigned to each actua-
tor/controls. You can use this commission number to download the wiring
diagram, inspection records and further information from the Internet.

5) Resistant to vibrations during start-up or for failures of the plant. However, a fatigue strength may not be derived from this
6) The lifetime of modulating actuators 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
7) Cable length between actuator and AUMA MATIC max. 100 m. Not suitable for version with potentiometer in the actuator. Instead of the potentiometer, an RWG
has to be used in the actuator

with actuator controls AUMA MATIC AMExC 01.1 Operation instructions

4. Additional information to the wiring diagram legend
Information A:
A running indication is possible if blinker transmitter (S5) is installed
(opening and closing of contacts).
Direction CLOSE: Connections XK6 – XK7
Direction OPEN: Connections XK6 – XK8
Contacts remain closed in end position.
When connected to an external PLC, the blinking signal can be switched off
via the DIP-switches (table 4, page 32).
Information B:
The type of seating in the end positions is determined by the valve manufac-
turer. The setting is done at the programming switches S1-2 and S3-2
(see page 32). The tripping of a torque switch in an intermediate position
switches off the actuator and causes a fault signal.
The limit switches serve for signalisation when switching off by torque seat-
ing. They need to be set so that the appropriate switch is tripped shortly
before reaching the end position. If the torque switch trips before the limit
switch, the actuator is switched off and a fault signal is generated.
For further programming possibilities, e.g. self-retaining in operation mode
REMOTE, see table 4, page 32.
Information D:
The following faults are registered and can be transmitted to the control
room as a potential-free collective fault signal:
- Power failure
- Phase failure
- Motor protection tripped
- Torque switch tripped in mid-travel.
This signal can be switched off on the logic board, see table 4, page 32.
Information E:
Input signals according to DIN 19 240.
The nominal operation current of inputs XK2, XK3, and XK4 amounts to
10 – 15 mA. If the internal voltage 24 V DC is used for remote control, it
must only be connected via potential-free contacts.
Information F:
In case of wrong phase sequence, the running direction is automatically
adjusted. In case of a phase failure, the actuator stops. The fault is indicated
at LED V14 on the interface board (see page 31). For collective fault signal,
see information D.
Information G:
Potential-free contacts are available for signals. The internal control voltage
(XK11/+ 24 V and XK5/– 24V) must not be used for external lamps, relays,
etc.

5. Transport, storage and packaging
5.1 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 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 at
the change-over mechanism.
.Engage manual operation (figure 1):
Manually lift the red change-over lever while slightly turning the shaft back
and 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-over
lever. It is not necessary to use an extension. Excessive
force may damage the change-over mechanism.
.Attach handwheel onto the red change-over lever on shaft (figure 2).
.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 uncoated 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 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 corro-
sion show, apply new corrosion protection.
After mounting, connect actuator immediately to electrical
system, so that the heater prevents condensation.
5.3 Packaging
Our 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 PE
foil. For the disposal of the packaging material, we recommend recycling
and 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 original
spare parts.
.After mounting to valve/gearbox, touch up any possible
damage to paint finish.
.Increased temperatures at valve mounting flange or valve
stem:
If increased temperatures > 40 °C are to be expected at the
valve mounting flange or the valve stem (e.g. due to hot
media), please consult AUMA. Temperatures > 40 °C are not
considered with regards to the non-electrical explosion protec-
tion.
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 3) are delivered with bore
and keyway (usually according to ISO 5210).
For output drive type A (figure 5), 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 min. 8.8, refer to table 1) evenly crosswise.

carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of
such an electrician and in accordance with the applicable
electrical engineering rules.
.Observe warnings at the actuator:
Wiring diagram
The wiring diagram applicable to the actuator is attached to the handwheel
in a weather-proof bag, together with the operation instructions. In case the
wiring 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 fuse
For 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 mA
208 to 240 V AC = max. 325 mA
380 to 500 V AC = max. 190 mA
The maximum permissible fuse for controls with a rated power of 1.5 kW is
16 A (gL/gG), and for controls with a rated power of 7.5 kW, the value
amounts to 32 A (gL/gG).
Cable installation in accordance with EMC
Signal 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 cables
are laid close to the ground potential.
.If possible, avoid laying long cables and make sure that they are installed
in 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.

Heater
As standard, the control unit of the actuator is equipped with a heater to pre-
vent condensation within the actuator. Unless ordered otherwise, the heater
is internally supplied. For external supply (option), the heater always has to
be connected.
Some actuators are optionally equipped with an additional motor heater.
The motor heater is always externally supplied and has to be connected
according to the wiring diagram.
Actuator controls on wall bracket (accessory)
For version on wall bracket, please observe the following:
.Versions with potentiometer in the actuator are not suitable. Instead of the
potentiometer, an RWG has to be used in the actuator
.Permissible cable distance between actuator and AUMA MATIC amounts
to a maximum of 100 m.
.Preconfectioned cables for the connection between actuator and AUMA
MATIC on wall bracket can be obtained from AUMA on request.
In case no preconfectioned cables are used, the following has to be
observed in addition:
.Use suitable flexible and screened connecting cables.
.Connect the wires in correct phase sequence.
Check the direction of rotation before switching on (see page 24)
Subsequent mounting of the actuator controls on the actuator
In case the actuator and the actuator controls have different commission
numbers (refer to name plates), the designations of the terminal plan and
the wiring diagram (KMS . . .) have to match for both devices.

.Before mains connection: Check whether type of current, supply voltage,
and frequency correspond to motor data (refer to name plate at motor).
Opening the terminal compartment
.Loosen bolts (1) (figure 11) and remove cover.
The terminal compartment is designed for explosion protection Ex e
(increased safety). The flameproof compartment (type of protection Ex d)
remains hereby closed.
.Insert cable glands with Ex e approval and of size suitable
for connecting cables.
(The enclosure protection stated on the name plate is only
ensured if suitable cable glands are used).
.Seal cable entries which are not used with suitable plugs.
Connecting the cables
.Connect cables according to order-related wiring diagram.
Cable cross sections:
- Power terminals (U, V, W) and
protective earth (symbol ) = max. 10 mm²
- Control contacts (1 to 50) = max. 2.5 mm² flexible, max. 4 mm2rigid
.For flexible cables use end-sleeves according to DIN 46228.
.After connection ensure that cable glands and screw plugs are fitted both
tightly and water-tight.
Closing the terminal compartment
.Clean sealing faces of housing and cover.
.Check whether O-ring is in good condition.
.Apply a thin film of non-acidic grease (e.g. Vaseline) to the sealing faces.
.Place cover and fasten bolts (1) evenly crosswise.
.Fasten cable glands with the specified torque to ensure the required
enclosure protection.
Disconnection from the mains without removing the wiring
If the actuator must be taken from the valve, e.g. for service purposes, it can
be separated from the mains without having to remove the wiring (figure 12).
For this purpose, the screws (2) are removed and the entire plug/socket
connector is pulled off. Cover and frame remain together.
Flameproof enclosure! Before opening, ensure that no
explosive gas and no voltage is present.
Before fitting the terminal connection:
.Clean sealing faces of housing and cover.
.Check whether O-ring is in good condition.
.Apply a thin film of non-acidic grease (e.g. Vaseline) to the sealing faces.
.Preserve joint surfaces with an acid-free corrosion protection agent.
Flameproof enclosure! Handle cover and housing parts with
care. Joint surfaces must not be damaged or soiled in any
way. Do not jam cover during fitting.
Fit terminal connection and fasten 4 bolts (2) evenly crosswise.
Parking frame, protection cover (accessories)
A special parking frame (figure 13) for protection against touching the bare
contacts and against environmental influences is available.
The open terminal compartment can be closed using a protective cover (not
illustrated).

9. Manual operation
The 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 operation
engages (figure 14).
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 15), if necessary, push it back manually.
Operating the change-over lever while the motor is running
(figure 16) can lead to increased wear at the change-over
mechanism.
.Turn handwheel into desired direction (figure 17).
Disengaging manual operation
Manual operation is automatically disengaged when motor is started again.
The handwheel does not rotate during motor operation.
