Hello everybody again.

 

I received yesterday mi order from BMS

 

-- Half Twist Throttle with LED Voltage Level Display - Voltage : 36V

-- Brake Grip 1

-- 36V11.6Ah Bottle Wave

-- Q85 36V250W Front Driving V-Brake E-Bike Motor Wheel - RPM : 328

 

I set up the controller S06S Hall Sensor Sine Wave for a max speed of 35 km/h, and:

 

P1 - 202

P2 - 0 as I don't have external speed sensor

P3 - 0

P4 - 0

P5 - 15

 

and the only thing that appears in the display is the 03 Error ,each time that I try to use the throttle.

 

Any advice it will be very welcome

The controller should be fine, the 03 error is I believe a motor phase problem.

There are 36 different combinations for the 3 phase wires and only a few about 6 combo's will work also I think you will need a speed sensor for the system to work although you don't necessarily need pas sensor.

First, check your motor connections. Probably, one of the bullets isn't fully home.

 

Do the colours on the hall wires match on each side of the connector?

I disconnected the throttle ,all the wires in the motor match each other ,and there is no error now ,so looks like something is wrong with the throttle.

 

The colours on the connector in the throttle don't match the connector in the controller ,the throttle has red, black and white, apart of other three loose cables with green, brown and yellow ,I guess that the last three are for the battery charge indicator, but in the controller, if I follow the diagram , the connector are red, black and blue.

I will post more pictures later on ,as I am not at home now.

Green is gor the throttle LEDs. Brown and yellow are the switch. You don't need them because you have the switch and battery indicator in the LCD.

 

For the throttle, red goes to red, black to black and signal to signal.

 

Disconnect PAS, throttle and brakes. Check thst you have 5v between red and black throttle or PAS wires, then connect only the throttle to see if it works.

 

The controller would have been set to work, so, if it still doesn't work, put the settings back to what they were.

 

Did you use HWBS. If so, you probably had one the wrong way round. They go at the caliper end of the cable.

Thanks for the help.

 

I don't have PAS , now I fit up the throttle matching wires and there is no error anymore ,put the settings back to the controller as I found it in the box

 

P1 132

P2 1 (I don't have external speed sensor ,I guess that it must be o for me)

P3 0

P4 0

P5 09

 

And the throttle still doesn't work ,I tried different combinations with the three motor wires ,follow the diagram ,and nothing.

Where I supposed to fit the green cable for the throttle Leds?

 

I am not using HWBS.

And the throttle wires voltage was???

I need to buy a tester tomorrow.........

Hello again

The throttle wires voltage is 4.4v and matching wires, red with red, black with black and signal with signal (white with blue) ,according with the S06S diagram.Now appears again the 03 error motor Hall signal abnormality each time that I try to use the throttle.

d8veh ,You were right ,one of the bullets wasn't fully home ,now the throttle is working ,the wheel spin a little bit ,like 3 seg ,very slow and with a weird noise ,and then stop it.I guess that at this point I have to try all the combinations for the 3 phase wires .......

Yes, but check that there's no damage to the motor cable where it comes out of the axle first.

Everything was good in the motor cable ,I have now 3 combinations that work fine ,same max speed ,where I have to check the Amps of each one to find the best?
