Emergency Stop Design and Testing
E-stops are for people, not for convenience.
Design points
| Item | Practice |
|---|---|
| Placement | Reachable from every operating position |
| Type | Mushroom head with a maintained action |
| Reset | Manual reset, and it must not restart the machine |
| Scope | Defined clearly: which equipment does it stop |
| Labelling | Identify what each device stops |
Testing
- Test each device at the stated interval and record the result.
- Confirm the whole stop chain, including drives and peripherals.
- Re-test after any modification to the cell.
Emergency stop requirements follow the applicable standards and risk assessment. Confirm with a competent person.
