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.
1.2
Commissioning
(electrical connection)
During electrical operation certain parts inevitably carry lethal voltages.
Work on the electrical system or equipment must only be carried out by a
skilled electrician himself or by specially instructed personnel under the con-
trol and supervision of such an electrician and in accordance with the appli-
cable electrical engineering rules.
1.3
Maintenance
The maintenance instructions (refer to page 17) must be observed, other-
wise a safe operation of the actuator is no longer guaranteed.
1.4
Warnings and notes
Non-observance of the warnings and notes may lead to serious injuries or
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 procedu-
res in these operation instructions. Each is marked by the appropriate picto-
graph.
This pictograph means: Note!
“Note” marks activities or procedures which have major influence on the cor-
rect 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.
1.5
Further notes
This pictograph means: Procedure may have been performed by valve
manufacturer!
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!

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.
