4. Replacement Cycle & Indicators
| Duty | Replace Every | Cycles | Warning Signs |
| Standard | 5–7 years | 1 M | Roller wear >1 mm, >1 Ω resistance |
| Commercial | 3–4 years | 0.6 M | Contact welding, IP54 failure |
| High-speed | 2–3 years | 0.4 M | Cam scoring, vibration >2 g |

Replace immediately if:
– Contact welding or housing cracks
– Repeated “door lock fault” without mis-alignment
– Roller temperature >70 °C during normal run

Maintain one spare **DL-5EN** per 25 doors for <4-hour response.
