1.6 Warning about misuse
In case of improper use or manipulation of the safety switch-
gear, personal hazards or damages to machinery or plant
components cannot be excluded when safety switchgear is
used. The relevant requirements of the standard ISO 14119
must be observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages result-
ing from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary re-
pairs, conversions and modifications to the device are strictly forbidden;
the manufacturer shall accept no liability for damages resulting from
such invasive work, arbitrary repairs, conversions and/or modifications
to the device.

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 BPS 300,
BPS 303 or BPS 303 SS actuators can be used, conventional magnets
are not suitable.
The safety switchgears are classified according to
ISO 14119 as type 4 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 300 with
integrated safety-monitoring module) and the actuator (BPS 300/
BPS 303 or BPS 303 SS) 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.
