Operation instructions AUMA NORM
1. Safety instructions
1.1 Range of application AUMA part-turn actuators are designed for the operation of industrial valves,
e.g.butterfly valves and ball valves.
For other applications, please consult us.The manufacturer is not liable for
any possible damage resulting from use in other than the designated appli
cations.Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the
actuators’designated use.

damage.Qualified personnel must be thoroughly familiar with all warnings
and notes in these operation instructions.
Correct transport, proper storage, mounting and installation, as well as care
ful commissioning are essential to ensure a trouble-free and safe operation.
The following references draw special attention to safety-relevant procedures in these operation instructions.Each is marked by the appropriate pictograph.
This pictograph means: Note!
“Note” marks activities or procedures which have major influence on the correct operation.Non-observance of these notes may lead to consequential
damage.
This pictograph means: Electrostatically endangered parts!
If this pictograph is attached to a printed circuit board, it contains parts
which may be damaged or destroyed by electrostatic discharges.If the
boards need to be touched during setting, measurement or for exchange, it
must be assured that immediately before a discharge through contact with
an earthed metallic surface (e.g. the housing) has taken place.
This pictograph means: Warning!
“Warning” marks activities or procedures which, if not carried out correctly,
can affect the safety of persons or material.

If actuators are delivered mounted to a valve, this step has been done in the
valve manufacturer’s plant.
Setting must be checked during commissioning!
2. Short description AUMA part-turn actuators type SG 03.3 – SG 04.3.have a modular design.
Manual operation is possible without change-over.
The limitation of travel is realised via limit switches in both end positions.
They are sized in such a way that the motor current can be switched directly
by them.When a switch is tripped in the end position, the motor power
supply is immediately interrupted.

4. Transport and storage
5. Packaging Our products are protected by special packaging for the transport ex works.
.
Transport to place of installation in sturdy packing.
.
Do not attach ropes or hooks to the handwheel for the purpose of lifting by
hoist.
.
If part-turn actuator is mounted on valve, attach ropes or hooks for the
purpose of lifting by hoist to valve and not to part-turn actuator.
.
Store in well-ventilated, dry room.
.
Protect against floor dampness by storage on a shelf or on a wooden pal
let.
.
Cover to protect against dust and dirt.
.
Apply suitable corrosion protection agent to bright surfaces.
If part-turn actuators are to be stored for a long time (more than 6 months),
the following points must be observed additionally:
.
Prior to storage: Protect bright surfaces, in particular the output drive parts
and mounting surface, with long-term corrosion protection agent.
.
Check for corrosion approximately every 6 months.If first signs of corro
sion show, apply new corrosion protection.
After mounting, connect part-turn actuator immediately to electrical mains,
so that condensation is prevented by the heater.
The packaging consists of environmentally friendly materials which can
easily be separated and recycled.
For the disposal of the packaging material we recommend recycling and collection centres.
We use the following packaging materials:
Wooden material boards (OSB)/cardboard/paper/PE film

6. Fitting the ball handle/
manual operation
To avoid damage during transport, the ball handles are fitted to the inside of
the handwheel. Prior to commissioning, the ball handle has to be fitted in
the correct position.

not required. The handwheel does not rotate during motor operation.
Turning the handwheel during motor operation results in
an extension or reduction of the operating time, depending
on the direction of rotation.
Pull out ball handle and re-insert in cor
rect position.

.
Prior to mounting the part-turn actuator must be checked
for any damage.
.
Damaged parts must be replaced by original spare parts.
.
After mounting to valve, touch up any possible damages
to paint finish.
.
For butterfly valves the recommended mounting position is end position
CLOSED.
(Prior to mounting, bring the part-turn actuator to the mechanical end stop
CLOSED by turning the handwheel clockwise).
.
For ball valves the recommended mounting position is end position
OPEN. (Prior to mounting, bring the part-turn actuator to the mechanical
end stop OPEN by turning the handwheel counter-clockwise).
.
Thoroughly degrease mounting faces of part-turn actuator and valve.
.
Place coupling sleeve on to valve shaft and secure
(refer to figure A2, detail A or B), ensure that dimensions X, Y and Z are
observed (refer to table 2).
.
Apply non-acidic grease at splines of coupling.
.
Fit actuator so that fixing holes in actuator and valve mounting flange are
in alignment.
If necessary, move actuator up or down one tooth on the coupling.
If required, turn handwheel a little in direction OPEN or CLOSE until holes
align to the threads.
.
Ensure that the spigot (if provided) mates uniformly in the recess and that
the mounting faces are in complete contact.
.
Fasten the actuator with bolts of minimum quality 8.8 using lock washers.
Fasten bolts crosswise to the appropriate torque according to table 2.

.
Check whether mechanical end position of the valve corresponds to the
mechanical end stop of actuator by turning at handwheel (clockwise for
end position CLOSED)
.
If necessary, remove screw plug (22.1, figure B1) and adjust mechanical
end stop at hex.socket head cap screw (21.1, figure B3).Turning clock
wise results in smaller, turning counter-clockwise results in larger swing
angles.
.
Never remove the screws (21.2,figure B2 and 21.1, figure
B3) completely, because this will cause oil leakage.

The limitation of travel is realised via limit switches
(page 11) in both end positions. For this reason the end
stops of the actuator have to be set to a slightly larger swing
angle (approx. by 2° larger) than the swing angle actually
required by the valve.
