single start command for a hazardous movement.
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 TESZ 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 depending on the required safety level.
