Range Of Application - AUMA SAEx 25.1 Operation Instructions Manual

•
Protective measures The end user or the contractor are responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment for
the staff.
Maintenance To ensure safe device operation, the maintenance instructions included in this manual
must be observed.
Any device modification requires prior written consent of the manufacturer.

1.2 Range of application

AUMA multi-turn actuators SAEx/SAREx are designed for the operation of industrial
valves, e.g. globe valves, gate valves, butterfly valves, and ball valves.
The devices described below are approved for use in the potentially explosive atmo-
spheres of zones 1, 2, 21, and 22.
If temperatures > 40 °C are to be expected at the valve flange or the valve stem (e.g.
due to hot media), please consult AUMA.
Temperatures > 40 °C are not considered with regards to the non-electrical explosion
protection.
Other applications require explicit (written) confirmation by the manufacturer.
The following applications are not permitted, e.g.:
•
•
•
•
•
•
•
•
•
•
•
No liability can be assumed for inappropriate or unintended use.
Observance of these operation instructions is considered as part of the device's desig-
nated use.
These operation instructions are only valid for the "clockwise closing" standard ver-
sion, i.e. driven shaft turns clockwise to close the valve. For "counterclockwise closing"
version, a supplement must be observed in addition to these operation instructions.
Particular conditions of use
The particular conditions of use are listed on the certificates supplied. Among others,
this includes the following conditions:
•
•
•
During operation, the housing warms up and surface temperatures > 60 °C may
occur. To prevent possible burns, we recommend checking the surface temperat-
ure using an appropriate thermometer and wearing protective gloves, prior to
working on the device.
