ChongXiao Intelligent Brushless Sine Controller 36V 48V 60V 72V 84V 2000W Maximum Current 50A Aluminium Alloy E-Bike Brushless Motor Controller for Electric Bicycle Scooter

Note:The instruction manual attached to the product is a series of universal manuals for the product. The images shown in the manual may differ from those of this product, but most of the functions of the product are the same, with some differences in certain functions. There may be some discrepancies between the image taken and the actual situation. Please refer to the received product for accuracy. and the position of the power and phase lines of this controller is somewhat different from traditional controller designs, as it does not have external wires and instead has hidden interfaces. Their wiring position requires opening the back cover for wiring, and then covering it up. This design is to avoid being exposed to rain and causing short circuits, making it a safer upgraded interface. The reverse gear designed by the factory is just a signal line Don't ask why We are unable to explain. So the reverse gear with only one wire is not a defect of the product, it is the design of the product. There is only one wire for reverse gear, which is the reverse gear signal wire. The negative wire can be any black negative wire of the controller. (It can be connected to the signal line for reverse throttle, and the other negative wire for reverse throttle can be connected to any black negative wire of the controller) Please be know it before purchasing. thank you. Material: aluminum alloy and plastic Voltage: 36v-84v universal Power: 1000W-2000w all can work Current Limit: Rated current 40A, maximum output 50A. Condition: Since the process is die-casting and injection molding, the product itself will have small flaws, please don't mind. 1.hall（5 wires） 2.three -speed gear 3.reverse gear（only 1 wire,this is signal wire，If you have 2 wires, the other one can be connected to the common negative wire） 4.Phase Meter 5.throttle 6.Multi data instrument cable 7.Intelligent recognition（also call self-learning line） 8.speed cruise wires 9.high-level brake 10.Hall Meter 11.electric door lock 12.Job three-speed gear（if throttle 3 speed plug only have 2 wires,can connect it,if not have，not need connection） 13.Differential motor dedicated(2 wires,if want use square wave function,let they connect together，controller will change to square wave controller) 14.low-level brake 15.anti-theft alarm power 16.anti-theft alarm signal How to connect controller？ 1.connect the motor phase line(color to color connection） 2. connect the hall line,color to color connection.(if motor without hall line, don't need connect，but motor will have noise) 3. connect the battery line(+:battery+ , -:battery-) 4.off power,let two intelligent recognition lines connect together,open power,then the wheel will forward or reverse. (1.if wheel forward ,Separate the intelligent recognition line. 2.if wheel reverse, Separate the intelligent recognition line. Let intelligent recognition line connect together again,if wheel forward ,Separate the intelligent recognition line.) This step needs to be effective within 2 minutes after the power is turned on. If the timeout occurs, please turn off the power and then turn it back on before proceeding with these steps. 5. connect the controller throttle to throttle and need color to color connect, connect controller electric door lock to throttle electric door lock （if throttle not have electric door lock,let controller electric door lock short） NOTE:when use throttle control speed,two intelligent recognition line must separate. 6.other functions can be connected as needed.
