FAQ
1.What are the conditions for the safety light curtain to be working properly?
When the emitter and receiver are in working condition, the emitter's red light remains on, and the receiver's green light is illuminated. When the light curtain is obstructed, there is no change in the emitter's indicator light, but the receiver's light changes from green to red, and the digital display shows the number of blocked light beams. When there is no obstruction, the receiver returns to its normal state with a constant green light.
2.Is the new light curtain compatible with the existing system?
We provide 1:1 customized replacement of the original light curtain data connector, with compatibility including electrical interfaces, communication protocols, and mechanical installation. Please compare the specifications of existing light curtains with ours, or contact our technical support team to help you find a compatible replacement model.
