2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The TESF hinge safety switch has been designed to prevent, in con-
junction with the control part of a machine, movable safety guards from
being opened before hazardous conditions have been eliminated. They
are also suitable for fitting on profile sections and existing equipment.
Hinge safety switches can only be used for applications, in
which the hazardous condition is terminated without delay
(e.g. run-on movements) when the safety guard is opened.
The user must evaluate and design the safety chain in
accordance with the relevant standards and on the requi-
red safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

under certain circumstances.
