The certification is not a guarantee for that the realized functional safety is sufficient for any machine. The
OEM system integrator is responsible for analyzing the hazard and risks for a particular machine and
evaluate if the risks are sufficiently reduced by the provided safety functions.
System integrator responsibility
The OEM integrator is responsible for the following:
•
Maintaining an organization responsible for functional safety of the system
•
Ensuring that only authorized and trained personnel perform functional safety related work
•
Choosing reliable components
•
Completing a System Hazard & Risk Analysis and establishing the required risk reduction targets
•
Reassessing the hazard & risk every time the system is changed
•
Ensuring that the derived risks are properly reduced by the safety functions provided by the JS1-H
Steer by Wire steering joystick
•
Approving certification and homologation of the entire system to the desired risk reduction level
•
Installation, set-up, safety assessment, and validation of the interfacing sensor sub-systems
•
Validating that the safety functions reduce the risks as expected
•
Any related non-safety standards that should be fulfilled for the application and its components
•
Verifying the environmental robustness suitability of the JS1-H Steer by Wire steering joystick to
installation in the final system in its surrounding environment
•
Periodically inspecting for errata information updates
Safety architecture
The following illustration shows the abstract safety architecture of JS1-H Steer by Wire. Due to the
applicable safety requirements, the joystick implements different levels of redundancy for securing
safety-related functions.
