The main working principle of the safety light curtain is that when the safety light curtain is running, if there is an object blocking the beam, the safety light curtain will send a signal to stop the machine, so as to achieve the function of safety protection. So what is the operating state of the safety light curtain when it is running?

The operating state of the safety light curtain is mainly divided into three states: no blocking, blocking and retreating.

1. When there is no object blocking, the receiver is in the light receiving state when there is no object blocking the safety light curtain. At this point, the red light on the receiver turns off and the yellow light on the transmitter turns on. At this time, the working switch of the protected equipment is pressed, and the equipment is in a normal operation state. The green light on the transmitter is always on.

2. In the normal operation of the equipment, when there is an object blocking the beam, the red light on the receiver is on, the protected equipment is in a controlled state and is forced to stop running.

3. When the object exits, when the object blocking the signal exits the protection zone, the safety grating resumes normal operation and sends a signal to keep the equipment running.

Through the above analysis of safety light curtain manufacturers and operating status, we can grasp its operating status at any time. When workers use it, they can judge whether the light grid is running normally and find faults in time.
