4.5.1.5 Extension with second laser scanner
Only in conjunction with the variant with automated reset, the safety system can be
extended by a second safety laser scanner. This may be necessary if the robot area to
be monitored cannot be monitored with a single safety laser scanner.
DANGER
Failure to observe manufacturer obligations
This adaptation is
not part of this safety system!
Implementation of the adaptation described in this chapter makes you the manufac‐
turer of a safety system.
b
Carry out the adaptation of the safety system described here only subject to own
responsibility.
b
Comply with all manufacturer obligations for development and implementation of
a safety system.
NOTE
The manufacturer must adapt the documentation (circuit diagrams, SISTEMA) corre‐
spondingly if the safety system is extended with a second laser scanner.
The OSSDs of the second laser scanner can be connected to I7 and I8 of the
UE410-8DI module. No other changes to the program or wiring are necessary.
