1) fine adjustment: by adjusting the angle of the limit touch point of the upper limit switch 201 itself.
2) Large position offset: by adjusting the angle of the upper outer arm 701 to the connecting shaft 11.
For the lower limiting mechanism, (1) when the user controls the roller shutter motor 1 to roll the roller shutter downwards through the control module (including the field knob, the remote APP or the WEB), the roller shutter motor 1 drives the roller shutter extending wall 8 to move downwards. When the roller shutter motor touches the lower outer arm 702, the lower outer arm 702 is urged to press downwards, the lower outer arm 702 drives the lower inner arm 602 to press downwards through the connecting shaft 11, meanwhile, the lower connecting spring 502 is gradually tensioned, the lower inner arm 602 presses downwards to a certain extent and then contacts the lower limit switch 202, so that limit matching is realized, the lower limit switch 202 informs the control module that the lower limit is reached, and the control module controls the roller shutter motor 1 to stop moving.
(2) When a user controls the roller shutter motor 1 to roll up the roller shutter upwards from the lower limit position through the control module (comprising a field knob, a remote APP or WEB), the roller shutter motor 1 drives the roller shutter extending wall 8 to move upwards. The lower connecting spring 502 is forced to be gradually reduced as the roller shutter motor 1 moves upward until the roller shutter motor 1 leaves the lower outer arm 702. But the connecting spring 502 will remain open under the influence of the lower outer arm 702 itself.
(3) When the limiting position of the roller shutter changes due to weather or aging influence, the roller shutter can be adjusted in two ways:
1) fine adjustment: by adjusting the angle of the limit touch point of the lower limit switch 202 itself
2) Large position offset: by adjusting the angle of the lower outer arm 702 to the connecting shaft 11.
