1. Safety instructions
1.1. Basic information on safety
Standards/directives Our products are designed and manufactured in compliance with recognized
standards and 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.
Safetyinstructions/warn-
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 exclusively by suitably qualified personnel having been authorized 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 recognized 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 conformance to these regulations, standards, and laws.
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.
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 recognized rules for occupational health and safety.
●Observe the national regulations.
●During operation, the housing warms up and surface temperatures > 140 °F
(60 °C) may occur.To prevent possible burns, we recommend checking the
surface temperature using an appropriate thermometer and wearing protective
gloves, if required, prior to working on the device.
Protective measures The end user or the contractor is responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment
for the staff.
Maintenance To ensure safe device operation, the maintenance instructions included in this manual
must be observed.
Any device modification requires prior written consent of the manufacturer.

2.2. Short description
Multi-turn actuator Definition in compliance with EN 15714-2/MSS SP-102 (EN ISO 5210):
A multi-turn actuator is an actuator which transmits to the valve a torque for at least
one full revolution.It is capable of withstanding thrust.
Figure 6: Example, SAEx 25.1 multi-turn actuator
AUMA multi-turn actuators SAEx 25.1 –SAEx 35.1/SAREx 25.1 –SAREx 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.Controls are required to
operate or process the actuator signals.

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.
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.

The product described in this document can be operated without restriction in any
mounting position.
4.2. Handwheel fitting
Information For transport reason, handwheels with a diameter 15.7”(400 mm) and larger are
supplied separately within the scope of delivery.
Damage at the change-over mechanism due to incorrect assembly!
→Only pivot change-over lever manually.
→Do NOT use extensions as lever for operation.
→First engage manual operation correctly, then mount handwheel.

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
retaining ring.
When exchanging the output drive sleeve, later retrofitting to a different output drive
type is possible
