1. Safety instructions
1.1. Prerequisites for the safe handling of the product
Standards/directives The end user or the contractor must ensure that all legal requirements, directives,
guidelines, national regulations and recommendations with respect to assembly,
electrical connection, commissioning and operation are met at the place of installation.
They include among others:
●Standards and directives such as IEC 60079 “Explosive atmospheres":
- Part 14: Electrical installations design, selection and erection.
- Part 17: Electrical installations inspection and maintenance.
●Applicable configuration guidelines for fieldbus applications.
Safety instructions/
warnings All personnel working with this device must be familiar with the safety and warning
instructions in this manual and observe the instructions given. Safety instructions
and warning signs on the device must be observed to avoid personal injury or property
damage.
Qualification of staff Assembly, electrical connection, commissioning, operation, and maintenance must
be carried out by suitably qualified personnel authorised by the end user or contractor
of the plant only.
Prior to working on this product, the staff must have thoroughly read and understood
these instructions and, furthermore, know and observe officially recognised rules
regarding occupational health and safety.
Work performed in potentially explosive atmospheres is subject to special regulations
which have to be observed.The end user or contractor of the plant is responsible
for respect and control of these regulations, standards, and laws.
Electrostatic charging Highly efficient charge generating processes (processes more efficient than manual
friction) on the device surface must be excluded at any time, since they will lead to
propagating brush discharges and therefore to ignition of a potentially explosive
atmosphere.
This also applies to fireproof coatings or covers available as an option.
Ignition dangers Gearboxes were subjected to an ignition hazard assessment in compliance with the
currently applicable standard according to ISO 80079-36/ -37.Hot surfaces,
mechanically generated sparks as well as static electricity and stray electric currents
were identified and assessed as major potential ignition sources.Protective measures
to prevent the likelihood that ignition sources arise were applied to the gearboxes.
This includes in particular lubrication of the gearbox, the IP protection codes and the
warnings and notes contained in these operation instructions.
Commissioning Prior to commissioning, imperatively check that all settings meet the requirements
of the application. Incorrect settings might present a danger to the application, e.g.
cause damage to the valve or the installation.The manufacturer will not be held
liable for any consequential damage. Such risk lies entirely with the user.
Operation Prerequisites for safe and smooth operation:
●Correct transport, proper storage, mounting and installation, as well as careful
commissioning.
●Only operate the device if it is in perfect condition while observing these instruc-
tions.
●Immediately report any faults and damage and allow for corrective measures.
●Observe recognised rules for occupational health and safety.
●Observe national regulations.
●During operation, the housing warmsup andsurfacetemperatures>60°Cmay
occur.To prevent possible burns, we recommend checking the surface temper-
ature prior to working on the device using an appropriate thermometer and
wearing protective gloves.

2. Short description
Part-turn actuator Definition in compliance with EN 15714-2/EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution.It need not be capable of withstanding thrust.
AUMA part-turn actuator Figure 1: AUMA SQEx 10.2 part-turn actuator
[1] Part-turn actuator with motor and handwheel
[2] Actuator controls
[3] Local controls with display, (a) selector switch and (b) push button
[4] Valve attachment
AUMA part-turn actuators SQEx 05.2 –SQEx 14.2/SQREx 05.2 –SQREx 14.2 are
driven by an electric motor.For manual operation, a handwheel is provided.Switching
off in end positions may be either by limit or torque seating.Actuator controls are
required to operate or process the actuator signals.
For non-intrusive version (control unit:electromechanical version), limit and torque
setting is made via switches within the actuator.
For non-intrusive version (control unit:electronic version), limit and torque setting is
made via the actuator controls, neither actuator nor the actuator controls housing
have o be opened.For this purpose, the actuator is equipped with an MWG (magnetic
limit and torque transmitter), also capable of supplying analogue torque feedback
signals/torque indication and analogue position feedback signals/position indication
at the actuator controls output.
Actuator controls The actuator controls ACExC 01.2 may be mounted directly to the actuator or
separately on a wall bracket.
The actuator can be operated via the push buttons on the local controls of the actuator
controls or settings can be made in the actuator controls menu.The display shows
information on the actuator as well as the menu settings.
The functions of the actuator controls include standard valve control in OPEN-CLOSE
duty, positioning, process control, logging of operating data, diagnostic functions
right through control via various interfaces (e.g. fieldbus, Ethernet and HART).
App and software
Using the AUMA CDT software forWindows-based computers (notebooks or tablets)
and the AUMA Assistant App, actuator data can be uploaded and read, settings
can be modified and stored.The connection between computer and AUMA actuator
is established wireless via Bluetooth interface.With the AUMA Cloud, we provide
an interactive platform to collect and assess e.g.detailed device data of all actuators
within a plant.

Long-term storage For long-term storage (more than 6 months), observe the following points:
1. Prior to storage:
Protect uncoated surfaces, in particular the output drive parts and mounting
surface, with long-term corrosion protection agent.
2. At an interval of approx.6 months:
Check for corrosion.If first signs of corrosion show, apply new corrosion protec-
tion.

5.1. Mounting position
When using grease as lubricant, the product described herein can be operated in
any mounting position.
When using oil instead of grease within the actuator gear housing, perpendicular
mounting position is specified whereby the flange is pointing downward.The type of
lubricant used is indicated on the actuator name plate (short designation F...= grease;
O...= oil).
5.2. Handwheel fitting
Figure 11: Handwheel

[4] Retaining ring
How to proceed 1. If required, fit spacer [1] on input shaft [2].
2. Slip handwheel [3] onto input shaft.
3. Secure handwheel [3] with retaining ring [4].
Information: The retaining ring [4] (together with these operation instructions)
is stored in a weatherproof bag, which is attached to the device prior to delivery.
5.3. Mount actuator to valve
Corrosion due to damage to paint finish and condensation!
→Touch up damage to paint finish after work on the device.
→After mounting, connect the device immediately to electrical mains to ensure
that heater minimises condensation.
The actuator is mounted to the valve using a coupling (standard) or via lever.Separate
instructions are available for actuator mounting to the valve when equipped with
base and lever.

Application ●For valve attachments according to EN ISO 5211
●For rotating, non-rising valve stem
5.3.2. Mount actuator (with coupling)
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the actuator to the valve (e.g.with bore and keyway, two-flat
or square bore).
Assemble valve and actuator in the same end position. As standard, the actu-
ator is supplied in end position CLOSED.
→Recommended mounting position for butterfly valves: End position CLOSED.
→Recommended mounting position for ball valves: End position OPEN.
Assembly steps 1. If required, move actuator in same end position as valve using the handwheel.
2. Clean mounting faces, thoroughly degrease uncoated mounting surfaces.
3. Apply a small quantity of grease to the valve shaft [2].

4. Place coupling [1] onto valve shaft [2] and secure against axial slipping by using
a grub screw [3] or a clamping washer and a screw with curved spring lock
washer [4].Thereby, ensure that dimensions X,Y or L are observed (refer to
figure and table <Mounting positions for coupling>).

6. Fit actuator. If required, slightly turn actuator until splines of coupling engage.
Figure 15:
Information Ensure that the spigot (if provided) fits uniformly in the recess and that the flanges
are in complete contact.
7. If flange bores do not match thread:
7.1 Slightly rotate handwheel until bores line up.
7.2 If required, shift actuator by one tooth on the coupling.
8. Fasten actuator with screws.
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.
9. Fasten screws crosswise to a torque according to table.
