Manufacturer of the machine
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state of the machine may not be stopped or not be stopped in a timely
manner in the event of non-compliance with the following instructions.
b
Use of the safety system requires a risk assessment. Check whether additional
protective measures are required.
b
Comply with the applicable national laws, regulations and standards 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 laser scanner.
The manufacturer must check whether the individual components of the safety system
are suitable for the respective application depending on the risk assessment and ambi‐
ent conditions. Among other things, it is necessary to take into account the size of the
protective fields and the requirements for the machine design.
The manufacturer has the following duties:
b
Carrying out a risk assessment
b
Verifying and validating the safety functions
b
Integrating the individual components in accordance with the appropriate stan‐
dards
b
Compliance with the applicable laws, regulations and standards.
4.1.1
Notes on automated restart
The automated restart function may only be used if a comprehensive and detailed man‐
ufacturer’s risk assessment has been performed and all requirements for use of this
safety system are fulfilled.
There is no necessary requirement for a general restart interlock in ISO 10218-2. Chap‐
ter 5.10.3.3 of ISO 10218-2 makes explicit reference to a presence sensing function in
order to prevent a restart. This conforms with the basic safety and health requirements
and standards of the Machinery Directive.
If the operator is reliably detected in the monitored area and there is no possibility of
entering the hazardous area undetected, the automated restart complies with the
requirements of the standard.
4.1.2
Reference standards
The following standards must be taken into account when preparing and using the
safety system:
