Safety instructions
1.1
Range of application
AUMA 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
actuator’s 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
control and supervision of such an electrician and in accordance with the
applicable electrical engineering rules.
1.3
Maintenance
The maintenance instructions (refer to page 27) must be observed, other-
wise a safe operation of the actuator is no longer guaranteed.
1.4
Warnings and notes
Failure to observe 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
careful commissioning are essential to ensure a trouble-free and safe oper-
ation.
During operation, the multi-turn actuator warms up and surface tempera-
tures > 140 °F may occur. Check the surface temperature prior to contact in
order to avoid burns.
The following references draw special attention to safety-relevant proce-
dures 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 consequen-
tial 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.

Short description
AUMA part-turn actuators type SG 05.1 – SG 12.1 and SGR 05.1 – SGR 12.1
have a modular design. The part-turn actuators are driven by an electric
motor. A handwheel is provided for manual operation. The limitation of travel is
realised via limit switches in both end positions. Torque seating is also
possible in both end positions. The type of seating is determined by the valve
manufacturer. Additionally, a mechanical end stop is provided for the protec-
tion of the valve. This is not, however, designed to be approached during
normal operation.
