Operation manual G9SR
In order to use the G9SR system safely, the precautions listed in this manual indicated by
alert symbols and descriptions must be followed. Failure to follow all precautions and
alerts may result in an unsafe use or operation.
The design of a safety control function follows the requirements of:
- the risk assessment acc. EN ISO 12100-1.
This step defines the measures needed in risk reduction.
- the basic principles of machinery safety acc. EN ISO 13849-1
- the basic principles for electrical safety acc. EN 60204-1
In addition it is required to check the structure of the entire safety system (EN ISO
13849-1), the diagnostic coverage and the robustness against common cause failures.
This all is needed to check the calculation of the safety system reliability.
The customer must implement measures to ensure compliance with these standards.
After installation, a comparison between the specified and the installed safety function is
mandatory. This final step is verifying the function of the safety system. Make sure that
in the final step that all requirements defined based on the risk assessment are met.
Detailed information about validation can be found in ISO 13849-2.
