FAQ for D4NL-1AFG-B
How does the guard lock mechanism work?
Spring-loaded lock engages automatically when door closes. Solenoid must be energized to release lock. Machine can only run when lock is engaged (door closed AND locked). Prevents access while hazardous motion continues.
What's the difference between solenoid release and power-to-lock?
Solenoid release (D4NL): locked by default, power releases. Safer for power failure (door stays locked). Power-to-lock: requires power to lock. Choose solenoid release for safety, power-to-lock for applications requiring manual release during power loss.
What safety category does this achieve?
Category 4, Performance Level e (PL e), SIL 3 when used in properly designed safety circuit. Highest safety rating for guard locking applications. Suitable for high-risk machinery (presses, robots, centrifuges).
How do I wire the 4NC + 1NO contacts?
4NC safety contacts: wire in series to safety relay/monitor for dual-channel safety circuit. 1NO monitor contact: wire to PLC input for door status indication. Never use monitor contact for safety function.
What's the 1300N lock force?
Lock can withstand 1300N (130kg/286lbs) of force before failing. Prevents forced entry while machine is running. Required by safety standards for guard locking applications.
