- Protective device scope
- Photoelectric sensors, sensing edges, light arrays and vehicle-detection accessories serve defined roles. Quantity, mounting, wiring condition and operator requirements determine repair and test work.
- Access above the opening
- Ceiling height, hood location, stored goods, mezzanines and nearby services affect safe reach to brackets, barrel and operator. Lifts, platforms and material-handling arrangements are planned accordingly.
- Testing and documentation
- Normal cycles, manual operation, protective responses, fire-door procedures and facility records vary by assembly. The proposal can name the demonstrations, measurements and written results included at handover.
