What is the potential impact of a malfunctioning door edge?

A malfunctioning door edge can have serious implications for the safe operation of a passenger elevator. Specifically, if the door edge is not functioning correctly, it can lead to an inability to detect obstructions. The door edge plays a crucial role in ensuring the safety of passengers by sensing when there is an object or person in the doorway. This detection mechanism is essential to prevent the doors from closing on people or items, which could cause injuries or damage.

When the door edge is defective, it may fail to send signals that would typically stop or reverse the door's movement upon encountering an obstruction. This failure compromises the safety systems designed to protect passengers and can lead to accidents. Therefore, understanding the function of the door edge and the risks associated with its malfunction is critical in ensuring the proper safety measures are in place in elevator systems.
