METER FUNCTION DESCRIPTION
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 to under 25 km/h. |
| 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 an 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 kilometers or miles is controlled by the 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 the 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 |
| 13 | Switch to start mode | Switch the scooter to power-assisted or non-power-assisted startup mode through Bluetooth command configuration; information via Bluetooth, the instrument will report the vehicle configuration information via Bluetooth upward machine/APP. |
| 14 | E level implementation mode | When the speed is greater than 3km, the motor can be started. The 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. |
| 16 | P mode | Park the scooter through Bluetooth, NFC, or a mechanical key. |
Error reporting Function
| Error Code | Error Item | Reasons |
| O1E | Over-current protection | The current exceeds the limit. |
| 02E | low-voltage protection | battery voltage lower than 43V |
| 03E | Short circuit of motor phase line | Short circuit of motor phase line when unlocking |
| 04E | Motor block protection | Motor blocked or short circuit or drive failure |
| 05E | Drive upper bridge failure | Drive upper bridge MOS tube damage or breakdown |
| 06E | Drive down bridge failure | Drive down bridge MOS tube damage or breakdown |
| 07E | Hall problem for the motor | Hall line sequence is wrong or poorly connected |
| 08E | The high temperature of the motor | Motor temperature higher than the normal working temperature |
| 09E | Throttle problem | Hall problem for the throttle or poorly connected |
| 10E | Left rake problem | Brake problem or poorly connected |
| I IE | communication failure between the instrument and electronic controller electronic controller | Instrument problem or poorly connector for the communication signal wire signal wire |
| 12E | The instrument received data timeout failure | Instrument problem or poorly connector for the communication wire |
| 13E | Battery Communication Failure | Poor contact of the battery communication wire or defective device |
| I4E | Controller firmware missing | Instrument and controller communication failed or were unable to communicate |
| 16E | The battery protection board is missing | The battery program upgrade failed |
| I 7E | Instrument firmware is missing | Instrument program upgrade failed |
| I 8E | Turn and turn back | Do not turn back on the startup |
| I 9E | Left brake handle not in a position | The left brake handle is not in position on the boot |
Display Function
NFC key card: In the off state, the NFC key card is close to the screen to turn on and unlock; in the power-on state, the NFC key card is close to the screen, shut down, and lock the scooter.
Function button: Short press the function button to turn on the product, and press it for about 3s to turn it off. Press the function button to turn on/off the headlight when power-on.
Press twice to switch to E (pedestrian mode) /L (economy mode) /II (sports mode) when power-on.
E mode is the pedestrian mode, with a maximum speed of 5km/h, which is suitable for use on pavement. L mode is the economy mode, with a maximum speed of 15km/h;
H mode is sports mode, with a maximum speed of 25km/h;
Press five times in riding mode to switch the speed unit;
APP turns on the cruise function, which maintains a constant speed. When the vehicle speed is greater than 5km/h, press and hold the function button for 2 seconds to enter cruise mode at a constant speed.
Brake handle: Squeeze the brake handle which will control both the disc brake and the electromagnetic brake. Press the throttle to accelerate the scooter.
FCC Statement:
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
