Detailed Product Description

The power will be cut off automatically when the transmitter is not in use. It's matched with left and right converting switches and can be adjusted by the converting switches if the running direction of the motor is opposite to the actual direction.

Moving up and down can be controlled by each other; the motor will stop if user presses any button when the motor is working. The manual function is the same. The relay folds if press the button "up", and the "up" relay will cut off automatically if there's no loop in the output lead, the "down" control is the same as the "up" control.

Rebound when meets obstacles: when the door is moving down, the system control the motor at once to make the door stop descending if the infrared detector ray is blocked by the obstacles, and rebound to the up limit. So it avoids damages to the obstacles and the rolling door during the door descending. (This function must be matched with infrared detector).
