AUMA Electric part-turn actuators SG 05.1 - 12.1_SGR 05.1 - 12.1 NORM - Manual (Page 4)

1. 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 applications.
Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the actua-
tor’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 elec-
trician himself or by specially instructed personnel under the control and super-
vision 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, otherwise 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 operation.
During operation, the multi-turn actuator warms up and surface temperatures
> 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 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.
2. 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. Addition-
ally, a mechanical end stop is provided for the protection of the valve. This is not,
however, designed to be approached during normal operation.
