2.2. 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 actuators SQ 05.2 –SQ 14.2/SQR 05.2 –SQR 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.
Actuator controls AC 01.2 actuator controls are used to operate AUMA actuators and are supplied
ready for use.The actuator controls may be mounted directly to the actuator or
separately on a wall bracket.
The functions of the AC 01.2 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).
Local controls/
AUMA software Operation, setting, and display can be either performed directly at actuator controls
or alternatively from Remote via binary input signals, or using another interface.
The following options are available at the actuator controls in local operation:
●The actuator can be operated via the push buttons of the local controls or set-
tingscanbemade in the actuatorcontrolsmenu.Thedisplayshows information
on the actuator as well as menu settings (contents of these instructions).
●Using the AUMA CDT software for Windows-based notebooks or the AUMA
Assistant App for Android-based devices, data can be uploaded and read
whereassettingscanbemodifiedandstored.Theconnectionbetweencomputer
and actuator controls is wireless via Bluetooth interface (not included in these
instructions). AUMA CDT software can be downloaded free of charge from our
website www.auma.com.
Intrusive - Non-Intrusive ●Intrusive version (control unit: electromechanical):
Limit and torque setting is performed via switches in the actuator.
●Non-Intrusive version (control unit: electronic):
Limit and torque setting is performed via the controls, without removal of actu-
ator or actuator controls covers.For this purpose, the actuator is equipped with
anMWG(magneticlimitandtorquetransmitter),also capabletosupplyanalogue
torque feedback signals/torque indication and analogue position feedback sig-
nals/position indication at the actuator controls output.

6. Fit part-turn actuator.If required, slightly turn part-turn actuator until splines of
coupling engage.
Figure 12:
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 part-turn actuator by one tooth on the coupling.
8. Fasten part-turn actuator with screws.
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.

4.4. Mounting positions of local controls
Figure 13: Mounting positions
The mounting position of the local controls is implemented according to the order.
If, after mounting the actuator to the valve or the gearbox on site, the local controls
are in an unfavourable position, the mounting position can be changed at a later
date.Four mounting positions shifted by respectively 90° are possible (by maximum
180° into one direction).
4.4.1. Mounting positions: modify
Hazardous voltage!
Risk of electric shock.
→Disconnect device from the mains before opening.
Electrostatic discharge ESD!
Risk of damage to electronic components.
→Earth both operators and devices.
1. Loosen screws and remove the local controls.
2. Check whether O-ring is in good condition, correctly insert O-ring.
3. Turn local controls into new position and re-place.
Cable damage due to twisting or pinching!
Risk of functional failures.
→Turn local controls by a maximum of 180°.
→Carefully assemble local controls to avoid pinching the cables.
4. Fasten screws evenly crosswise.

5.1. Basic information
Danger due to incorrect electrical connection
Failure to observe this warning can result in death, serious injury, or property damage.
→The electrical connection must be carried out exclusively by suitably qualified
personnel.
→Prior to connection, observe basic information contained in this chapter.
→After connection but prior to applying the voltage, observe the <Commissioning>
and <Test run> chapters.
Wiring diagram/terminal
plan The pertaining wiring diagram/terminal plan (in German or English) is attached to
the device in a weather-proof bag, together with these operation instructions.It can
also be requested from AUMA (state order number, refer to name plate) or
downloaded directly from the Internet (http://www.auma.com).
Permissible networks
(supply networks) Actuator controls (actuators) are suitable for use inTN andTT networks with directly
earthed star point for mains voltage up to maximum 690 V AC.Use in IT networks
for nominal voltages up to maximum 600 V AC are permissible. For IT network, a
suitable, approved insulation monitor measuring the pulse code is required.
Current type, mains
voltage, mains fre-
quency
Type of current, mains voltage and mains frequency must match the data on the
actuator controls and motor name plates.Also refer to chapter <Identification>/<Name
plate>.

External supply of the
electronics For external electronics supply with 24 V DC and simultaneous use of DC motors
(24 V DC, 48 V DC, 60 V DC, 110 V DC, 220V DC), the 24 V DC controls’voltage
supply should be ensured via the XK25/26 terminals, separately from the power
supply (U1, V1). In case of common supply using a single cable (links from U1, V1
with XK25/26, for 24V DC only !!!), short-term excess or falling below the permissible
voltage limits can be the consequence during switching (24 V DC +10 %/–10 %).
Anypossibly incoming operationcommandsarenotexecutedoutsidetheadmissible
limit values.The actuator controls briefly signal a fault condition.
Protection and sizing on
site For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches have to be provided by the customer.
The current values for sizing the protection can be derived from the current
consumption of the motor (refer to motor name plate) plus the current consumption
of actuator controls.
We recommend adapting the switchgear sizing to the max.current (Imax) and selecting
and setting the overcurrent protection device in compliance with the indications in
the electrical data sheet.
