Several cases of glass lifter failure
Hits：793 Date：2017/7/17
Glass lifts occasionally there will be several cases of failure of the situation, in many cases, we only need to move hands can be resolved.
1. Soft stop function:
The descending position of the lifter is limited and the glass falls directly to the bottom of the lifting mechanism and the bottom dead center impact, the frequent impact will greatly reduce the service life of the lifter, while the direct drop in the end there will be a significant impact noise.
In order to avoid the above problems, the elevator through the intelligent control system first preset a lower limit soft stop position, to reach the lower limit point before the 5mm distance, through the intelligent control system to stop the system to stop running, then continue to press the button, There is also a small drop of space. Through a key drop function glass down to the end, found the glass slightly higher than a few millimeters for the normal phenomenon.
2. False trigger anti-folder function:
When the window glass automatically rising during the resistance is too large or encountered obstacles, it will automatically stop rising and make it downward movement, is its own anti-folder function, to avoid misuse and cause personal injury; anti-folder after the trigger 10s Inside, the lifter does not have a key lift function. Such as the following circumstances, such as lifting the window glass, there may be abnormal sound and lifting difficulties such as the phenomenon, will trigger a serious anti-folder protection:
(1) vehicles in the violent bumpy road lift glass;
(2) foreign body caught in the window (such as limbs, branches, etc., to avoid harm to the human body);
(3) closing the door in the process of lifting the glass;
(4) the window is not used for a long time, foreign body bonded to the window.
3. Thermal protection function:
When the window glass continuous lift more than 10 times, will trigger the elevator motor thermal protection function to protect the motor operating temperature does not exceed the limit value to prevent the motor overheating burned.
The first time into the thermal protection, the window will stop working, waiting for 30 seconds after the time, re-allow the elevator to complete a complete rise and fall process; if the initial thermal protection, 30 minutes again because of continuous operation into the second Thermal protection, then it must wait 30 minutes before allowing the motor to work.
