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. What tests should I perform after installing a new light screen?

We suggest conducting functional testing and security verification to ensure that the new light curtain can function properly. The testing items include detection range, response time, and alarm function.

3.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.

4. Do you provide OEM services for safety light curtain sensors?

Yes, we provide comprehensive OEM services, including customized product selection and laser marking. Our team works closely with clients to understand their unique requirements and provide them with tailored solutions. We can flexibly meet the application needs of different industrial scenarios, from customizing sensor sizes to integrating specific functions.
