In the process of using the safety grating, we may encounter some common problems, such as the safety grating is unstable to light. So what is the cause of this problem? Based on years of industry experience, the following results are analyzed:

1. The distance of the beam has exceeded the limit of the grating itself and needs to be re-adjusted.
2. The pairing of the transmitter and the receiver is not at a uniform level. When the deviation between the transmitted and received light is 5 degrees or less, it is more difficult to illuminate.
3. The safety grating has been used for too long, and too much dirt or dust accumulated inside will cause instability to light.
4. The safety grating is subject to external interference, and the shielded wire needs to be connected.

If the safety grating is unstable to light, you can check the cause from several aspects. If you still can't find the source of the problem, you can directly consult the manufacturer who purchased the grating. Have professional maintenance personnel perform counseling or return to the factory for repair.
