Appearance, Size, and Material
The LCD-S866 features an outer shell made of durable ABS plastic. The liquid crystal display is protected by a high-hardness acrylic window, offering scratch resistance comparable to tempered glass.
Working Voltage and Wiring
This display is compatible with various operating voltages, including DC24V, 36V, 48V, and 60V. Custom voltage options may also be available. The document details the standard wiring sequence for connecting the display to the controller, including color coding for power, control, ground, and data lines.
Key Features and Functions
The LCD-S866 offers a comprehensive range of functions:
- Display Functions: Real-time speed, battery level indicator, fault prompts, total mileage, and single trip mileage.
- Control and Setting Functions: Power switch control, wheel diameter adjustment, automatic sleep time setting, backlight brightness adjustment, start mode selection, drive mode settings, voltage level configuration, and controller current limit adjustments.
- Communication Protocol: Utilizes the UART protocol for data communication.
Display Content and Fault Codes
The display provides detailed information, including battery level, multi-function data such as total mileage (ODO), single mileage (DST), battery voltage (VOL), and operating time (TM). It also shows current operating current, instantaneous power (WATT), and various fault codes. A table is provided to help users understand the meaning of different fault codes, such as communication failures, motor issues, and battery undervoltage.
