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 BNS-B20 safety sensor is designed for application in safety circuits
and is used for monitoring the position of movable safety guards to EN
1088 and EN 60947-5-3. To actuate the safety sensors, only the BNS-
B20-B01 actuator can be used, conventional magnets are not suitable.
The safety sensors are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.
The entire system consisting of the BNS-B20 safety door handle switch
and the safety-monitoring module (AES, SRB) meets the requirements
of the standard IEC/EN 60947-5-3.
Connecting multiple BNS-B20 safety sensors to one AES safety-moni-
toring module is technically possible. To connect multiple safety sensors
(check if authorised!), the NO contacts are wired in parallel and the NC
contacts in series. The Protect-IE-11 or -02 or PROTECT-PE-11 (-AN)
input expander module can be used to connect up to 4 safety sensors
with NC/NC or NC/NO contacts.
BNS-B20 safety sensors equipped with LED's shall not be wired in
series, except with the Protect-IE input expander module. As a result of
this, the luminosity of the LED's would considerably decrease and the
voltage could drop below the minimum input voltage of the downstream
safety-monitoring module.
