The Roller shutter is composed of a variety of door pieces. It is a door that rotates up and down in the fixed slide way with the roller above the door as the center. What is the reason why it cannot be closed?
If the green light of the ground sensing control machine is constantly on, the automatic manual switch cannot be operated; The reset button on the ground sensor must be pressed and held for more than 5 seconds. After release, the red light remains on and the green light goes out. If the green light remains on after resetting, please inquire for inspection; Is there a corresponding volume around the ground loop
2. When the Roller shutter of Jinan is in the automatic state, the door body is still falling after the set delay closing time. Is the infrared light checked red or green? Green indicates normal status, while red indicates a malfunction. Adjust the infrared position appropriately until the green light is on;
3. The Roller shutter is stuck or the door sling falls off.
4. When the door body repeatedly runs, it seems that it runs repeatedly. If there are objects or curtains blocking infrared rays during the inspection of the door lowering process, corresponding measures should be taken to eliminate them.
The main frame profile of Roller shutter made by unique technology is connected by plastic parts, and the screw fixing at the connection adopts hidden design, which improves the appearance of the door. The connection between the profile and plastic parts adopts stamping and drilling to make the door structure firm. Cross connection design: The cross tube is stamped with a special process and tightly combined with the circular tube, which not only makes the door truss structure more firm, but also ensures smoother operation.
The Roller shutter uses a special motor to drive the intermediate shaft of the roller shutter to rotate to the roller shutter switch. When it reaches the upper and lower limits set by the motor, it will stop automatically. I hope the above content is helpful to you.
