How to adjust the limit of electric rolling gate?

The upper and lower limits of the electric shutter door can be debugged according to the following steps:

1. First, you can pull the chain vertically downward to make the shutter door rise to the height of 1 m, and then turn on the power supply. After starting, you can press the buttons on the controller to test the sensitivity of the shutter door, where the top represents rising, the bottom represents falling, and the stop represents stopping.

2. After ensuring the flexible use of the rolling shutter door, dial the nut card on the limiter for debugging at all angles, and try to disengage the limiter nut at the same time. Next, stop the shutter door at a proper position by ascending or descending, then rotate the limit nut to press the limit roller, and insert the nut into the slot after success.
