ZhilianhaiStandards for Robot Safety Circuits
What is addressed
| Element | Requirement |
|---|---|
| Architecture | Redundancy and monitoring appropriate to the risk |
| Performance | Reliability level required for each function |
| Verification | Positive testing and recorded results |
| Documentation | Drawings showing safety functions |
| Modification | Change control after commissioning |
Practical points
- Safety signals should not share components with standard control logic.
- Any change requires re-verification, however small it looks.
- Keep drawings updated; outdated safety drawings are a liability.
Safety circuit design is a specialist area. Involve a competent engineer from the start.
