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 protective gloves,
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.

to observe this warning results in death or serious injury.
Indicates a potentially hazardous situation with a medium level of risk.Failure
to observe this warning could result in death or serious injury.
Indicates a potentially hazardous situation with a low level of risk. Failure to
observe this warning could result in minor or moderate injury. May also be
used with property damage.
Potentially hazardous situation. Failure to observe this warning could result
in property damage. Is not used for personal injury.
Safety alert symbol warns of a potential personal injury hazard.

2. Identification
2.1. Short description
Multi-turn actuator Definition in compliance with MSS SP-102 (EN 15714-2/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.
AUMA multi-turn actua-
tor Figure 1: Example, SAEx 25.1 multi-turn actuator
AUMA multi-turn actuators SAEx 25.1 –SAEx 30.1/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.
Actuator controls ACExC 01.2 actuator controls are used to operate AUMA actuators and are supplied
ready for use. In combination with SAEx 25.1 –SAEx 30.1/SAREx 25.1 –SAREx
30.1 multi-turn actuators, they may be mounted separately on a wall bracket. For
high nominal motor currents of the actuator, the switchgear of the actuator controls
additionally require a control box.
Figure 2: Actuator controls and control box
[1] Actuator controls
[2] Control box
The functions of ACExC 01.2 actuator controls include standard valve control in
OPEN-CLOSE duty, positioning, process control, logging of operating data right
through to diagnostic functions.
Local controls/
AUMA CDT Operation, setting and display can be performed directly at the actuator controls.
When set to local control, it is possible to
●Operate the actuator via the local controls (push buttons and display) and per-
form settings (contents of these instructions).
●Read in or out data or modify and save settings via AUMA CDT software (ac-
cessory), using a computer (laptop or PC).The connection between computer
and actuator controls is wireless via Bluetooth interface (not included in these
instructions).

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
HP [kW] on the motor name tag. 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
tag does not indicate the power class but the max. rated power in HP [kW].

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.
Risk of damage due to excessively low temperatures!
→Actuator controls may only be stored permanently down to –22 °F (–30 °C).
→On request, actuator controls may be transported in specific cases and for short
duration at temperatures down to –76 °F (–60 °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.

10. Turn multi-turn actuator with handwheel in direction OPEN until valve flange
and output drive type A are firmly placed together.
11. Tighten screws [5] between valve and output drive type A crosswise applying
a torque according to table.

4.3.2. Design of output drive types B and E
Figure 16: Output drive type B
[1] Multi-turn actuator flange
[2] For output drive types B/B1/B2 hollow shaft with keyway
[2]* For output drive types B/B1/B2 solid shaft with bore and keyway
[3] Gearbox/valve shaft with parallel key
Information Spigot at valve flanges should be loose fit.
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

How to proceed 1. Check if mounting flanges fit together.
2. Check, if output drive of multi-turn actuator [1] matches the output drive of
valve/gearbox or valve/gearbox valve shaft [2/3].
3. Apply a small quantity of grease to the valve or gearbox stem [3].
