3.METER FUNCTION DESCRIPTION

3.1 Operation Function

No	Function Item	Function Description
1	Headlight Control	The headlights are turned on by default when the power

is turned on. The headlights are turned off when the power is turned off.

The headlights are blinking when looking for the scooter, and the

headlights are automatically turned off when charging.

2| Speed Limit| The speed limit mode is sent by the APP via Bluetooth to the meter, and then the meter sets the controller.

The speed is limited under 18mph.

3| Acceleration| When the power is on, the assist sliding speed exceeds 4 km/h (2.5 mph).

When the handle is pressed, the system will control the rotation of the hub

| | according to the depth of the handle press.

The lighter the press, the slower the speed, the faster the press, the faster the speed. The real-time speed is displayed in the first three words of the meter.

---|---|---
4| Brake| The brake is electronic brake + drum brake. When the brake is pressed, the system controls the output electromagnetic brake and slows down

gradually until the hub is locked.

5| Kick Start| The controller can drive the motor only when the speed of the kicking is

above 4 km/h or 2.5mph.

6| Speed Unit Switching| The speed unit of kilometer or mile is controlled by app via Bluetooth.

The speed unit can be changed by pressing the button 5 times.

7| Online upgrade| Controller firmware and instrument firmware can be upgraded through

Bluetooth.

8| Bluetooth control command receiving| It can receive instructions sent by mobile phone/upper computer via Bluetooth, analyze them, and perform corresponding actions, such as

turning on and off vehicle locks and headlights

9| Issue of control

instruction

| Relevant control instructions are sent through UART channel to control

the relevant actions of the controller.

10| Error Code Showing

and reporting

| The meter can display error code reported by its own judgment and

controller, and report to the upward computer/APP via Bluetooth timing.

11| Timely reporting of real-time vehicle

information

| The instrument reports the real-time status information of the body, such as current speed, VMT, total VMT, etc., through Bluetooth timing

up-position machine/APP

12| Vehicle configuration information report| After receiving the instruction to read the vehicle configuration

information via Bluetooth, the instrument will report the vehicle configuration information via Bluetooth upward machine/APP.

13| Switch to start mode| Switch the scooter to power-assisted or non-power- assisted startup mode

through Bluetooth command configuration;

14| E level implementation| When the speed is greater than 3km, the motor can be started. The
| mode| maximum speed is 5km. It can only be started with help, not without help, and the meter flashes at the same time.
---|---|---
15| On/off cruise mode| Configure the scooter to turn on or off the constant speed cruise mode by Bluetooth command.

3.2 Error reporting Function

Error Code	Error Item	Reasons
01E	Over current protection	The current exceeds the limit.
02E	low-voltage protection	battery voltage lower than 42V
03E	Short circuit of motor phase line	Short circuit of motor phase line when

controller

| instrument problem or poorly connector for the communication signal wire signal wire
12E| Instrument received data timeout failure| instrument problem or poorly connector for the communication wire
14E| Right rake problem| Hall problem for the throttle or poorly connected
15E| Controller firmware missing| Instrument and controller communication failed or unable to communicate
18E| Turn and turn back| Do not turn back on startup
19E| Left brake handle not in position| The left brake handle is not in position on boot
20E| Right brake handle not in position| The right brake is not in position when starting up
31E| High temperature of controller| The working temperature of the controller exceeds the normal temperature

3.3 Display Function

Powerbutton:

Long press to turn on, long press to turn off; after boot, click to turn on/off the headlights; double click to switch gears; short press 6 times to switch mile/mile;
Short press once power button to turn on/off the headlights while the vehicle is power-on;
Short press twice to switch to E (pedestrian mode) /L (economic mode) /H (sports mode) while the vehicle is power-on;
E mode is pedestrian mode, the maximum speed is limited to 3 mph, suitable for pavement implementation;
L mode is economic mode, the maximum speed is limited to 9 mph;
The H mode is sports mode, and the maximum speed is limited to 18 mph;
