Manufacturer of the overall system
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state of the overall system may not be stopped or not be stopped in a
timely manner in the event of non-compliance.
b
Use of the safety system requires a risk assessment. Check whether additional
protective measures are required.
b
Comply with the applicable national regulations derived from the application (e.g.,
work safety regulations, safety rules, or other relevant safety guidelines).
The safety system was developed under consideration of typical application cases. A
partial safety function can be implemented with the safety system in these application
cases. The manufacturer must check whether the safety system is suitable for its spe‐
cific application case (risk assessment).
If the thorough check shows that the safety system is not suitable for the specific appli‐
cation case, the safety system can be used as a basis for an individualized develop‐
ment suitable for the specific application case. This case will not be considered further
in this document.
In any event, additional work is necessary for the safety system to be used, e.g. subse‐
quent configuration of the safety controller.
The manufacturer has the following duties:
b
Executing a risk assessment.
b
Verifying and validating the safety functions.
b
Integrating the individual components in accordance with the appropriate stan‐
dards.
b
Please note that C standards have priority compared to statements about this
safety system.
4.1.1
Reasonably foreseeable misuse
The manufacturer must take into account the reasonably foreseeable misuse, among
other things, in the risk analysis. The following reasonably foreseeable misuse scenar‐
ios have been identified during development of this safety system:
Misuse by the manufacturer
•
The application has hazards that cannot be protected against by an electro-sensi‐
tive optical protective device.
•
The safety laser scanner works as an indirect protective measure and cannot pro‐
vide protection from pieces thrown from application nor from emitted radiation.
Transparent objects are not detected.
•
Incorrect design of the field sets, e.g. protective fields are designed to be too
small.
Misuse by the user/employee
•
The user may not bring any stools, seats, ladders, or other objects into the moni‐
tored area with which the user can climb over the scanning field into the haz‐
ardous area.
•
Transparent objects are not detected.
