Safety information
2.1
General safety note
The information and tools will not fulfill the safety requirements for your application
without further adjustments being made. The project planning provided by way of exam‐
ple is intended to serve as the basis to allow you to perform your own project planning
and configuration in line with your specific requirements. What this means is that the
information and tools merely provide an example to demonstrate how a safety function
can be taken care of.
When it comes to your own project planning and configuration, you will need to rely on
qualified staff given that it is your responsibility to ensure that the following require‐
ments are complied with at the very least:
b
Carrying out a risk assessment
b
Taking into account applicable standards
b
Verifying and validating the safety function
2.2
Intended use
The sBot Stop safety system provides protection against mechanical hazards caused by
movement of the robot arm by means of access and presence monitoring.
The safety system can be used subject to the following prerequisites:
•
Robots and humans perform their work in the same workspace, but at different
times (cooperation).
•
The robot works at a fixed position.
•
The danger results from the movement of the robot arm (mechanical hazard).
•
The only access to the robot is protected by the primary protective device (e.g.
safety light curtain).
•
The protective field of the safety laser scanner must be able to cover the entire
hazardous area (secondary protective device).
•
It is ensured that it is not possible to bypass the protective field of the primary pro‐
tective device and the safety laser scanner (e.g. by reaching around, stepping over,
climbing over or reaching through or standing behind). This is guaranteed, for
example, by fixed protective devices (e.g. fencing).

Coexistence
This safety system was developed for cooperative workspaces with robots.
Certain tasks that are performed by the robot may interact with the actions of humans.
Cooperative interaction between robots and humans is characterized by the fact that
tasks are performed in the same workspace at different times. If a cooperative interac‐
tion is monitored reliably, the robot arm can also work at high speeds.
