36V-48V 500W controller can work with hall join sensor or no longer connect corridor sensor Rated Voltage: 36V/48V/60V Low Voltage : 31V/42V/52V±0 Rated Power: 500W Limit Current:30A 1 2 line 3 line four brake five brake 6 (low/middle/high) 7 8 lock 9 line 10 instrument line eleven strength delivery 12 signal thirteen (red battery+, black battery-) 14 15 meter line 1 the motor line (color to color,if motor without corridor line, don&;t want join corridor line) 2 connect the battery line(red:battery + , black:battery-) 3 connect the controller throttle line to throttle, controller electric lock hook up with throttle electrical lock (if throttle not have electrical lock,the electric lock 2 wires of the controller could be docked together) 4 the 2 self-learning lines, the wheel will ahead or opposite (1 wheel forward ,Separate the self-learning line 2 wheel reverse, Separate the self-learning line Docking the self-learning line again, if wheel ahead ,Separate the self-learning line) Self-learning is to conform to the provision voltage 5 purposes could be linked as essential NOTE:Due to the manufacturing of goods from assorted factories, the wiring isn't always permanently matched, and the customer must regulate the wiring sequence themselves throttle want red to red, inexperienced to green, blue to blue connect, like the photo show, thank you
