The reason for abnormal closing of the high speed rolling shutter door

1. The rolling shutter door is always kept open. The reason for this problem may be that the sensor is damaged, and there is always a door opening signal input to the controller.

2. The curtain door is related to the door action, but it cannot be closed. The reason is that the sensor has the door signal input, that is, there is interference in the sensor induction range, compared with direct sunlight, flowing objects and unstable light sources.
