The main function of elevator light curtain sensor：

Elevator light curtain is an elevator door safety protection device, suitable for passenger elevators and freight elevators. It is installed on both sides of the elevator door to protect the safety of passengers.

How elevator light curtain sensor work：

The elevator light curtain sensor contains an infrared transmitter and receiver, which scans the elevator car door area to form an infrared protective light curtain sensor. When any one of the infrared rays is blocked, the elevator control system outputs a door-opening signal, and the elevator car door stops closing and opens in reverse direction. The elevator door will not close normally until the passengers or objects blocking the light leave the scanning area of ​​the elevator light curtain sensor. To prevent the elevator car door from catching people or objects.

Installation and debugging of elevator light curtain sensor：

Check whether the elevator light curtain sensor is installed firmly and whether the infrared emitter and receiver of the elevator light curtain are on the same plane.

Check whether the elevator light curtain sensor transmitter and receiver are correctly connected to the cable, and whether the cable is accurately connected to the power supply and control system.

After the elevator light sensor curtain is powered on, it starts to automatically detect and calibrate. After one second, the transmitter indicator light turns on and the receiver indicator light goes out, which means that the elevator light curtain sensor starts to work normally.
