If your safety system architecture requires guard locking upon a complete control system power failure (Power-to-Unlock), the D4BL-1 series should be specified instead. Ensure your safety relay logic distinguishes between locking configurations to prevent unexpected gate releases during voltage dips.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eSince this model is a Power-to-Lock device, a complete loss of electrical power will instantly release the guard locking force.
