The controller module receives a signal switch sensor or other detection signal of the drive motor, the control door according to appropriate manner. Design for China, without the use of a transformer. New built two auxiliary light sensor interfaces, accessibility interface, and further improve product safety and versatility. Security ◇ pinch when closed if the person or object, the door will reopen. Extrusion more sensitive sensor, the corresponding adjustment range greater. Safe return (stop) function when closed if pinch people, the door will (soon stop) turned to direction with it. Since then, the equipment moves adjustment feature automatically while confirming safety, while slowly closing. ◇ easier to open when a power outage, the female new technologies greatly reduce the force of the door, up to a maximum 2.8 kg lighter, easier to ensure that power is turned on. Reliability ◇ controller optimized structure, durable, easy to fault. Structural optimization, fault is not easy, using optocouplers pieces, as a control circuit thing "contact points", so, in addition to physical failure prone electrical contacts, making help prolong life, stable operation. ◇ smooth opening and closing operation, quiet. Switching operation can be adjusted according to the best of shape and leaf spot. Even in the fast reverse movement, there are the optimum braking control to prevent unstable operation. For the running resistance caused by increased pressure, but also improve the power of automatic correction function to keep running smoothly. Belt module changes the rotation of the motor into reciprocating motion of the module. The use of special materials technology toothed belt, scalability small, not temperature, high transfer efficiency, so do not make adjustments due to belt stretching. Belt tensioner module belt hanging on the belt tensioner module. The module is equipped with a belt tension adjustment mechanism. The engine case is made of high strength, wear aluminum. Can be easily cut, even in the opening width of the various local shops, etc., can also be adjusted on site, with the best size for installation. As the basic unit with 2.5 m length, according to the single open, double open configure different quantities, both for transportation, but also for opening offer might improve. Module for door hangers hanging. The module is equipped with hanging round on, you can move the engine compartment rails. New materials for hanging round to ensure long life. Each hanger can independently achieve ± 3 mm Height adjustment, further simplifying installation. Motor module uses small size, high power brushless DC motor, with high transmission efficiency, low noise, high-speed reduction gear box system, then the drive belt. Internal security apparatus, even if the frequent opening and closing, as well as long-term trouble-free operation. Motor drive pulley metal fabrication, free repair.
