The electric eye light source must align with what component?

The electric eye light source is a critical component in elevator safety systems, primarily used for ensuring that the elevator doors do not close on passengers or objects in the doorway. For the electric eye system to function correctly, the light source must align with the receiver. This alignment allows the receiver to detect the light beam and, in turn, initiate the appropriate safety responses.

When the electric eye light source and receiver are properly aligned, the system is able to create a continuous invisible barrier in the doorway. If an object or person interferes with this beam, the signal is broken, and the control system receives the cue to either halt or reverse the door motion. This alignment is essential for the reliable operation of the safety features in the elevator system, making it vital for protecting passengers.

In contrast, while components like the door actuator, safety edge, and limit switch play important roles in the functioning of an elevator, they do not form the direct optical link that is integral to the electric eye system. The actuator is responsible for the physical movement of the doors, the safety edge detects pressure to stop doors from closing on an obstacle, and the limit switch indicates the position of the elevator. These components are all part of the elevator's safety and control systems but do not
