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.
The multi-turn actuators SAI/SARI are qualified for use in nuclear power
plants and for DBE conditions inside containment.
As the case may be, deviations from the qualified versions may exist. These
deviations are discussed and agreed between customer and manufacturer.
Deviating versions are stipulated in the order acknowledgement and may be
enquired from AUMA stating the commission number (see name plate).
Before using the product, check whether the service conditions match those
in the order acknowledgement of the contractually stipulated version.
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 hazardous volt-
ages. 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 26) 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
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 60 °C 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.
2.
Short description
The actuators have a modular design. Gearing and switching systems are
mounted in a common housing.
The multi-turn actuators are driven by an electric motor.
The type of seating is determined by the valve manufacturer.
