This document describes the NINGBO TEVERUN TECHNOLOGY CO.,LTD Colorful TFT Display, model UKC2, a display unit designed for various applications, likely electric vehicles or similar systems.
Function Description
The UKC2 is a 3.5-inch colorful TFT screen that serves as a central information display and control interface. It provides real-time data, allows for system adjustments, and offers diagnostic information.
Key functions include:
- Information Display: Shows current speed (AVG, MAX, RT), mileage (Odometer, Trip distance), clock, riding time, battery status, output power, motor ON/OFF state, and real-time current and temperature.
- Control Interface: Allows users to adjust assist levels (ECO, 1, 2, 3, 4, 5), backlight brightness (5 levels), and switch between different display modes.
- System Settings: Provides access to a menu for configuring various parameters such as unit system (Metric/Imperial), power system voltage (48V/52V/72V), temperature protection thresholds (80-130°C), zero start (N/Y), auto-off time, wheel diameter (8-14 inch), cruise control (OFF/AUTO/MANUAL), ABS (ON/OFF), speed magnets (1-88), assist parameters (Assist1-Assist5), EABS level (1-5), F/R start level (1-5), F/R current limits, and export mode (NO/YES).
- Diagnostic Features: Displays error codes for maintenance purposes (Motor phase, Hall failure, Handlebar turning fault, Undervoltage protection, Controller error, Communication error, Over-temperature protection).
- Battery Information: If the system supports battery communication, it can display detailed battery information including voltage, capacity, cycle times, temperature, last uncharge time, remain capacity, and full capacity.
- Password Protection: Supports power-on password protection and allows for password reset.
- Software Upgrade: The software can be upgraded via UART.

Usage Features
- Power On/Off: Press and hold the Power button for 1 second. The display automatically shuts down after 10 minutes of no operation or ride (configurable).
- Assist Level Adjustment: Short press UP/DOWN buttons to change assist levels.
- Headlight/Display Mode Change: Press and hold the UP button for 1 second to turn on/off the headlight and switch between daytime/night mode. This also adjusts backlight brightness.
- Data Cleanup: Press and hold UP & DOWN buttons concurrently for 1 second to reset temporary data (AVG Speed, MAX Speed, Trip, Time).
- Menu Navigation: Double-press the M button (within 0.3 seconds) to enter/exit the parameter setting menu. Use UP/DOWN to select items, M to confirm, and POWER to cancel or go back.
- Speed Measurement: The number of speed measuring magnetic steel (magnetic pole) can be adjusted.
- Unit System: Configurable between Kilometer and Mile modes.
- Intelligent Power Indicator: Provides stable power indication, unaffected by motor start-stop fluctuations. If battery communication is supported, it displays an accurate percentage.
- Clock Function: Internal battery ensures the clock works even when the display is off.
- Cruise Control: Can be set to OFF, AUTO, or MANUAL.
- ABS: Can be turned ON or OFF.
- Export Mode: When enabled, speed is limited to 25% and requires an initial speed for motor power.
- Mounting: Clamps are suitable for 3 sizes of handlebars: 31.8mm, 25.4mm, and 22.2mm. Adapter rings are provided for 25.4mm and 22.2mm handlebars.
Maintenance Features
- Error Code Display: The display shows specific error codes (1, 2, 4, 5, 6, 7, 8) to help diagnose issues related to motor phase, Hall sensor, handlebar, undervoltage, controller, communication, and over-temperature.
- Factory Reset: A factory setting menu allows restoring all parameters (except odometer) to their default values.
- Software Upgradability: The ability to upgrade software via UART allows for future improvements and bug fixes.
- Screw Installation: Users are advised to pay attention to the screw's torque value during installation to prevent damage, as damages caused by excessive torque are not covered by the warranty.
