3.30SLC series safety light curtain, through the specific digital tube and indicator light, inform the user of the location of the light curtain fault and the cause of the failure, so that the user can better maintain:

1. When its own failure (such as the light source is not synchronized, the intensity of the light source is not enough, the light drive power path is wrong, the main control circuit is wrong, the cable is wrong, and the receiving drive circuit is wrong, the main control circuit is wrong, and the CPU is wrong) the light curtain can ensure that no wrong signal is sent to the controlled equipment to ensure the safety of the product; 

2. In order to pursue better safety in terms of output, dual independent OSSD outputs are adopted, so that automatic fault prevention has high safety, and can directly drive relays and safety PLCs
