ings 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.
Commissioning Prior to commissioning, it is important to check that all settings meet the requirements
of the application. Incorrect settings might present a danger to the application, e.g.

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 housingwarmsup andsurfacetemperatures> 60°C may

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
Multi-turn actuator Definition in compliance with EN 15714-2/EN ISO 5210:
A multi-turn actuator is an actuator which transmits torque to a valve for at least one
full revolution.It is capable of withstanding thrust.
AUMA multi-turn actuators SA 25.1 –SA 48.1/SAR 25.1 –SAR 30.1 are driven by
an electric motor and are capable of withstanding thrust in combination with output
drive type A.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 The AM 02.1 actuator controls are used to operate actuators and are supplied ready
for use.The controls may be mounted directly to the actuator or separately on a wall
bracket.For high nominal motor currents of the actuator, the switchgear of the actuator
controls additionally require a control box.The functions of the actuator controls
include standard valve control in OPEN-CLOSE duty, position indications and different
signals right through to position control (option).
Local controls Operation (via push-buttons), setting and indication can be performed directly at the
actuator controls (contents of these instructions).

3.2. Storage
Danger of corrosion due to inappropriate storage!
→Store in a 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.
Damage due to excessively low storage temperatures!
→AUMA MATIC actuator controls may NOT be stored below –40 °C
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.
3.3. Packaging
Our products are protected by special packaging for transport when leaving the
factory.The packaging consists of environmentally friendly materials which can easily
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.

4.3.2. Output drive types B and E
Application ●For rotating, non-rising valve stem
●Not capable of withstanding thrust
Design For output drive types B/B1/B2, the connection to the valve or the gearbox is made
by directly placing the multi-turn actuator hollow shaft onto the input shaft of the valve
or gearbox.
For output drive types B3/B4/E, the connection is made via output drive sleeve which
is inserted into the bore of the hollow shaft of the multi-turn actuator and fixed by a
