Four reasons why the fast rolling door cannot be closed normally

　　With the rapid development of China's industrial economy, the demand for large and fast rolling doors is increasing, and it is widely used in various industrial plants, logistics channels, workshops, warehouses, machine rooms, garages and other places. And some customers responded that the fast rolling shutter door could not be closed normally. What caused this?

　　1. Check the ground sense controller first: if the green light of the ground sense controller is on, the manual automatic switch cannot be operated at this time; you must press and hold the reset button on the ground sensor for more than 5 seconds, and the red light will be on after release. The green light is off; if the green light is still on after reset, please check if there is a corresponding volume iron around the sense coil.

　　2. In the automatic state, the door body has not been lowered beyond the set delay closing time. Check whether the infrared indicator is red or green. Green is the normal state. Red indicates a fault. Adjust the infrared position properly until the green light is on.

　　3. The door body of the quick door is stuck or the door strap is off.

　　4. The door body of the fast door runs repeatedly: When the door body repeatedly runs, first check whether there is an object or the curtain body itself cut off the infrared status during the descending process, and take corresponding measures to eliminate it.

　　The above are the four main reasons why the fast rolling shutter door cannot be closed normally. If you have other questions, please contact Xinyi Door Industry
