DANGER
H
azard due to unexpected starting of the machine
b
Affix the control switch for resetting the restart interlock outside the hazardous
area.
b
Make sure that the control switch cannot be activated by a person who is in the
hazardous area.
b
Also make sure that the person activating the control switch has a complete view
of the hazardous area.
4.5 Integration into the network of the control
4.5.1 Network topology
The device is suitable for the following network topologies:
•
St
ar
•
Line
•
Ring (Device Level Ring, DLR)
4.5.2 Integration of the safety laser scanner into the network
DANGER
D
anger due to unintended use of SIL 2 data of the safety laser scanner in SIL 3 applica‐
tions
b
Ensure that the safety-related data of the safety laser scanner is only used in
applications which do not exceed safety integrity level SIL 2 (IEC 61508) of the
safety laser scanner.
b
Be
fore integrating an already-configured safety laser scanner into a safety-related
network: reset the safety laser scanner to its factory settings, see "Factory set‐
tings", page 121.
