1. Light source interference is divided into strong light interference and reflection interference. Both of these disturbances are relatively easy to resolve. Where safety light curtains are used, ordinary lights can be used instead of strong lights. Reflection disturbances are due to the presence of a relatively bright object or mirror in the vicinity of the safety light grid, which can be resolved by moving it out of the light grid protection zone

2. Frequency converter interference, which is a problem encountered by ordinary domestic safety light screens. In this case, there are several ways to fix it. 1. Is there a shield wire in the safety light curtain communication cable used? If so, you must connect the shield wire and the ground wire; 2. Avoid wiring where there is a frequency converter; 3. An intermediate relay is connected to the light grid's The signal line is used to isolate the interference signal, and the power supply on the machine cannot be used in the field of the grating, so an independent switching power supply needs to be added. This advantage is also to avoid the interference signal being connected to the safety light curtain through the power supply; 4. If all the above problems cannot be solved, the safety light curtain manufacturer can go to the site to test according to the actual situation, and then modify it inside the light grid according to the interference source of the equipment.

3. Position juxtaposition interference means that the two machines installed on the safety light curtain are relatively close, or two light barriers are installed in parallel on one machine, and the signal sent by the transmitter of the first light grid is also received by the second light grid. received by the receiver, resulting in collocated interference, which is relatively easy to solve. As long as we slightly stagger the positions of the two sets of gratings, or swap the positions of one set of grating transmitters and receivers, the problem can be solved.

Fourth, external high-intensity signal interference, which is rarely encountered. In some factories, using wireless or specific frequency transmitters on the shop floor can also cause interference with gratings, so you need to stay away from these signals or turn them off.

4. When using the safety light curtain manufacturer's device, try to avoid using the grating around high-frequency machines, and handle the grounding wire of the safety device grating. The normal use of the safety device grating is not only to connect the wires correctly, but also to carry out regular maintenance so that the safety device grating can be used continuously.
