How to Replace the Light Curtain on a Passenger Elevator Door for Optimal Safety and Performance

Understanding the Light Curtain

Before diving into the replacement process, it’s important to understand what a light curtain does. It comprises a series of light beams that create an invisible barrier. When this barrier is compromised—say, by a person or obstacle—it triggers the elevator door to reverse, preventing injury. Regular maintenance and timely **passenger elevator door light curtain replacement** are essential for ensuring the reliability of this safety mechanism.
