Votol EM-200 Controller

I recently bought QS138 70 V3 kit with Votol EM200 sp2 controller with harness and 72V battery.
It didnt come with any explanation on what wire does what. I have trouble getting the motor to turn. Some sites say that there is single purple wire that needs to get 72 volts, without that it wont work. On another site I saw that pruple-grey wire needs 72 volts and purple wire needs 12V. It does confuse me a little. With 72V to purple I can connect to controller via PC and edit settings, but motor will still not turn.
Any help with links etc is appreciated. Spring is nearing and I'd like to get the project finished.
 
The colors differ between the harnesses. If you can connect to it via PC and you get the red led blinking, that means it's on. If you have the motor connected, no faults in the controller, proper motor configuration, and twist the throttle, the motor should turn. If it doesn't, star from the beginning.

You should start by looking at the big Votol thread here, as virtually everything for the smaller models (em-30, em-150) will apply to em-200 as well.
 
Here attached pls find the wiring definition of EM150-2&EM200-2SP controller for your checking.

Your brake level/pedal should have a sensor switch which closes as you apply brakes. If you have no brake light, then you can use low brake. Just connect one of the sensor wires to negative and the other one to the brake wire on the controller. Then change the port setting from high brake to low brake and check the low brake box in settings under regen amount.

If you have a brake light activated by your brake lever, just tie into the (+) side (between the brake sensor and brake light) and connect it to the brake wire of your controller and leave it at the default high brake settings.

Start low regen and test is with battery below 80% charge. Then progressively add more until had the desired braking. Regen is disabled if battery voltage is within 5v of your overvoltage setting. So get well below that to make sure your battery can absorb the full regen you set in EBS ratio %.

If you have throttle release regen on then you need to go to port settings to turn it off.

You don’t need a dc/dc converter to use high brake. Battery voltage is fine. The +12v they show means it will work for those who needed a dc/dc converter for their lights and accessories.

Choosing high or low brake is normally based on your brake light. Normally your brake lever sensor connects from battery (+) (for lights that are designed for that voltage) or the 12v from your dc/dc converter (normally found on conversions), or the output from your 72v/36v for when your bike has led rsted for 36-60v. The other wire of the brake sensor goes to the brake light AND to the brake wire on the controller. If you decide to use low brake you just change high brake port to low brake and also check the low brake box in the settings below regen %.
