1.6 Warning about misuse
In case of improper use or manipulation of the safety
switchgear, personal hazards or damages to machinery
or plant components cannot be excluded. 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
resulting from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary

2.3 Purpose
The safety sensor is used in AS interface systems for monitoring the
position of movable safety guards in accordance with ISO 14119 and
IEC 60947-5-3. The combination of the BNS 260 AS safety sensor,
the BPS 260-1/-2 actuator and the ASM safety monitor ensures the
safe monitoring of the condition of the corresponding safety guard. To
actuate the safety sensor, only the coded BPS 260-1/-2 actuators must
be used.
The safety switchgears are classified according to ISO 14119
as type 4 switching devices.
The safety function consists in safely switching off the code
transmission when the safety guard is opened and maintaining the safe
switched off condition for as long as the safety guard is open.
An AS-Interface Safety at Work component functions on the basis of
an individual code generator (8 x 4 bit). This safety code is cyclically
transmitted over the AS-i network and monitored by the safety monitor.
The component status can be evaluated through a PLC with AS-
Interface master. The safety-related functions are enabled by means of
the AS-i safety monitor.
LED display
The LEDs have the following meaning (to EN 62026-2):
Green LED
AS-Interface supply voltage
Red LED
AS-Interface communication error or slave address = 0
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
