1. When the operating room door of the hospital is running, the door often remains open but not closed. The main reasons are power failure, poor electrical connection, foreign object interference with safety anti pinch, green flashing door opening signal, resulting in the door body being constantly open but not closed. Another reason is the incorrect selection of the door opening direction.

　　2. The slow opening or closing of the hospital operating room door during operation is mainly due to the low setting value of the control device's speed knob for opening or closing the door; Excessive walking resistance, loose belt, insufficient tension, etc. So the speed knob for opening or closing the door of the control device can be adjusted accordingly; Turn off the power and manually move the door leaf to check for any obstacles in the moving parts; Adjust the belt tension.

3. As time goes by, the operating room door of the hospital may cause an increase in friction between the rubber strip and produce abnormal noise. We can change the distance between the ground wheel and the three frame vertical frame to increase the distance between them, and adjust the hanger wheel to adjust the door body to a position where it does not rub against the rubber strip; If it still cannot be solved, you can replace it with a small-sized silicone strip to solve the problem.

4. The three parts that are prone to abnormal noise are the friction between the track and the wheels, the ground wheel under the door body, and the friction between the rubber strips. The solution to the abnormal noise caused by rubber strip friction has been discussed above. As long as the friction between the track and the wheel is not properly maintained for a long time, the track is prone to dust, which can cause friction between the track and the wheel. The solution is to add some lubricant. The abnormal noise of the ground wheel is caused by friction between the door body and the ground wheel. It is necessary to place the ground wheel directly below the door body to solve the problem.

5. If it is a problem with the control unit, replace the controller and motor to operate normally. You can contact professional after-sales personnel for repair and treatment!
