maintained.
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 hinge safety switches (Type 1 according to ISO 14119) are suitable
for hinged guards, which need to be closed in order to provide for the
necessary operational safety.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
