1.headlight horn

2.E-ABS brake

3.low level brake

4.PAS

5.battery

6.LCD

7.electric door lock

8.self-learning line

9.hall

10.phase line

11.throttle

how to connect ？

1.connect the phase line (color to color）

2. connect the battery line(red wire :battery + , black:battery-)

3. connect the controller throttle line（color to color），connect electric door lock

（if your throttle not have electric door lock，controller electric door lock can be shorted）

4. connect the hall line(if motor without hall line, don't need connect)

5.docking the two self-learning lines, the wheel will forward or reverse.

(1.if wheel forward ,Separate the self-learning line.

2.if wheel reverse, Separate the self-learning line. Docking the self-learning line again，

if wheel forward ,Separate the self-learning line.)

6.other functions can be connected as needed.

LCD display communication protocol: UART

about introduction to LCD display parameters：

1. 1. Working voltage: 24V, 36V, 48V，52V，60V (the default is 36V, the buyer can set the voltage value by himself)..

Instrument 5-wire interface:

Red: Meter power cord

white: Power control wire of the controller

Black: instrument ground wire

Green: the data receiving line of the meter

Yellow: the data transmission line of the meter

2. Code Meaning:

E-06 is battery undervoltage. Check if the voltage set on the LCD matches the battery voltage? Either the battery is not fully charged, or it has been scrapped. Please replace the battery.

E-07 is a motor malfunction, with no wiring or poor contact at the Hall connector. If all of the above are good, it indicates that the motor Hall is faulty and needs to be replaced.

E-08 is a throttle malfunction. Check the throttle circuit and ensure that the connectors are in good contact. If the wiring is good, it means the throttle is faulty. Replace the throttle.

E-09 is a controller malfunction, please replace the controller.

E-10 is a communication reception fault.

1. Check if the instrument line is disconnected?

2. Check if the wiring between the controller and instrument is in good contact?

3. Unplug the power assist sensor and see if there is still an error message? If there is no error, it means that the power assist sensor is broken and needs to be replaced.

4. Pull off the accelerator and see if there is still an error message? If there is no error, it indicates an issue with the throttle. Please replace the throttle.

5. Remove the motor Hall wire and check if there is an error. If there is no error, it indicates that the motor Hall is broken and needs to be replaced.

3. Settings

P02: mileage unit, 00000 is KM; 00001is MILE;

P03: Voltage level: 24V, 36V, 48V, 52V,60V,default 36V;

P04: Sleep time: 0, no sleep; other numbers are sleep time, range: 1-60; unit is minute;

P05: Power-assist gear: there are 3rd, 5th gears adjustable;

P06: Wheel diameter: unit, inch; precision: 0.1;

P07: Number of speed measuring magnets: range: 1-255;

P08: Speed limit: the range is 0-100km/h, 100 means the maximum speed limit,

1. Communication status (controller control): The drive speed is maintained at the set value,

Error: ±1km/h; (both power assist and handlebar speed limit)

Note: The value here is based on kilometers. When the unit setting is converted from kilometers to miles,

The speed value on the display interface is automatically converted to the correct mile value, but this

The speed limit data set in the menu is not converted, which is inconsistent with the actual displayed mile speed limit value;

P09: Zero start, non-zero start setting, 00000 is zero start; 00001 is non-zero start;

P15: Default value, cannot be changed

P16: Default value, cannot be changed

P00:Default value, cannot be changed

P99: Default value, cannot be changed

Attention setting items: P02~P09 can be set, and it is not recommended to change the settings unless necessary.

For other settings on the instrument panel (P15~P99), you can take a look, but we suggest that you do not change them.

4. the button introduction:M is the power button

The key operation is divided into short press and long press, and combination key long press

Short press for quick/frequent actions like:

1. When riding, short press the up button or down button to modify the assist/speed gear;

2. Power button Switch the multi-function area to display data while riding, short press

Single button long press is mainly used for mode/switch state switching

Compound key (long press) is used for parameter setting, because the operation is complicated, which can reduce misoperation

(Short press does not make compound keys, because it is easy to trigger by mistake, and it is too difficult to operate)

Specific operation explanation:

1.If the current display is working, long press the power button, it will turn off the display, otherwise it will turn on the display

2. After the display screen is turned on, short press the M key to switch between display modes

3. Modify the assist ratio/electric gear

Assuming that it is currently in assist mode

1) Short press the up button, boost + 1

2) Short press the down button, boost - 1

4. Long press the power and up buttons to switch the display mode of speed.

5.Long press the up button to turn on or off the headlights.

6. Set parameters

Press and hold the up and down keys simultaneously to enter the parameter setting interface. The parameters that can be set include:

Wheel diameter (in inches), number of magnets, LCD brightness, undervoltage point, etc. (see settings: P02-P99);

In the settings interface, you can briefly press the up or down keys to increase or decrease the setting value. After modifying the parameters, it will flash. choice

After setting the value：

1. Short press the power button to switch to the next parameter while saving the set value of the previous parameter;

2. Alternatively, press and hold the up and down keys simultaneously to exit the settings and save the parameters. Otherwise, it will automatically exit and save the modified parameters after 10 seconds.

Note: Due to different production batches of products in different periods, some product parameters may differ slightly from those described in the manual, but it will not affect customer use.
