AUMA power class for
switchgear The switchgear used in the actuator controls (reversing contactors/thyristors) are
classified according to AUMA power classes (e.g.A1, B1, ....).The power class
defines the max. permissible rated power (of the motor) the switchgear has been
designed for.The rated power (nominal power) of the actuator motor is indicated in
kW on the motor name plate.For the assignment of the AUMA power classes to the
nominal power of the motor types, refer to the separate electrical data sheets.
For switchgear without assignment to any power classes, the actuator controls name
plate does not indicate the power class but the max. rated power in kW.

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 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.
Actuator controls ACExC 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 ACExC 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-
tingscanbemadeintheactuator controls menu.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
whereassettings can be modified and stored.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 (magnetic limit and torque transmitter), also capabletosupplyanalogue
torque feedback signals/torque indication and analogue position feedback sig-
nals/position indication at the actuator controls output.

Application ●For valve attachments according to EN ISO 5211
●For rotating, non-rising valve stem
4.3.1.1. Part-turn actuator (with coupling): mount to valve
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the part-turn actuator to the valve (e.g.with bore and keyway,
two-flat or square bore).
Information Assemble valve and part-turn actuator in the same end position. As standard, the
part-turn actuator 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 part-turn 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 part-turn actuator.If required, slightly turn part-turn actuator until splines of
coupling engage.
Figure 13:
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.
9. Fasten screws crosswise to a torque according to table.

4.4. Mounting positions of local controls
Figure 14: 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
Flameproof enclosure, danger of explosion!
Risk of death or serious injury.
→Before opening, ensure that there is no explosive gas and no voltage.
→Handle cover and housing parts with care.
→Joint surfaces must not be damaged or soiled in any way.
→Do not jam cover during fitting.
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.
