Reasons and solutions for slow opening speed of automatic door

1、 The current automatic door motor is driven by worm gear, but the reducer will also be worn and slippery after a long time of use, until the door leaf cannot be driven. In this case, only the corresponding motor parts can be replaced.


2、 First of all, eliminate the reason for the first power-on learning. At the beginning of each power-on, it will slowly run an opening and closing process, and re-detect the parameters such as the travel and weight of the door leaf.


3、 The old Panasonic motor is driven by a belt. There is a small belt on the back of the motor. For a long time, the teeth of the belt will be worn out after more than five years, and it will be worn down gradually. At this time, the small belt needs to be replaced. Most of the small belts are HTD363 s3m, with a face width of 5mm.


4、 If the door leaf cannot be closed normally continuously, that is, when the door leaf is not fully closed, someone approaches the automatic door and re-opens it. If this situation is continued for 4 or 5 times, the door leaf will re-learning and change to the slow detection state. At this time, people should leave the sensing range of the sensor and let people approach the automatic door after it is closed normally.
