After protective stop (with automated reset):
•
An automated restart may be implemented if this is permitted by the risk assess‐
ment of the robot application. The safety system performs an automated reset if
the protective fields of the primary protective device and the safety laser scanner
are clear. This switches the protective stop output to the ON state (HIGH) so that
the robot can be started.
•
The automated restart can be implemented in the robot controller or in a higher-
level control. Implementing automatic restart is the responsibility of the manufac‐
turer.

Physical guard
On the basis of the manufacturer’s risk assessment, it may be necessary to install fixed
guards such as fencing to avoid and restrict access to the hazardous area of the robot.
In addition to the applicable C standards for the application, the following standards
provide additional information on designing physical guards:
•
EN ISO 14120
•
EN ISO 13857
NOTICE
The possibility of entering the hazardous area by climbing over it, standing behind it or
reaching through it must be prevented.
