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 safety sensor is designed for application in safety circuits and is
used for monitoring the position of movable safety guards to ISO 14119
and IEC 60947-5-3. To actuate the safety sensors, only the BP 6, BP 8,
BP 10 or BP 15 SS actuators can be used.
The safety switchgears are classified according to
ISO 14119 as type 3 switching devices.
The safety switches are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.
Only the entire system consisting of the safety sensor (BNS), the actu-
ator (BP) and the safety-monitoring module (AES/SRB/AZR) meets the
requirements of the standard IEC 60947-5-3.
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.

If multiple safety components are wired in series, the Performance
Level to ISO 13849-1 will be reduced due to the restricted error
detection under certain circumstances.
