AUMA Electric multi-turn actuators SA 07.1 - 48.1_SAR 07.1 - 30.1 NORM - Manual (Page 4)

1. Safety instructions
1.1 Range of application AUMA actuators are designed for the operation of industrial valves, e.g.
globe valves, gate valves, 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 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
themselves 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 25) must be observed, otherwise 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 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 multi-turn actuators type SA 07.1 – SA 48.1 and SAR 07.1 – SAR 30.1 have
a modular design. The limitation of travel is realized 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.
