ANANDA D13 and D13/U Manual

Function Description

The ANANDA D13 and D13/U are compact LCD displays designed for electric bicycles (ebikes). They integrate a 2.4-inch multi-function screen and support 24V, 36V, and 48V batteries. The primary function of these displays is to provide real-time information about the ebike's operation and allow users to control various settings.

Key functions include:

• Total Mileage (ODO): Tracks the total distance the ebike has traveled.
• Trip Mileage (Trip): Records the distance for a single journey, which can be reset.
• Current Speed: Displays the ebike's instantaneous speed, with options to switch between KM/H and MPH.
• Light Status: Indicates whether the ebike's headlights are on or off.
• Pas Level: Shows the current level of power assistance, which can be adjusted by the user.
• Battery Capacity: Provides a visual representation of the remaining battery charge.
• Error Code: Displays specific codes if the ebike's control system encounters a fault, aiding in troubleshooting.
• Wheel Size: Allows for setting the wheel diameter to ensure accurate speed and mileage readings.
• Riding Time (Time): Tracks the duration of a single ride.
• Maximum Speed (MAX SPEED): Records the highest speed achieved during a ride.
• Average Speed (AVG SPEED): Calculates the average speed for a ride.
• Walking Assistant Mode: Provides low-speed assistance for walking the ebike.
• Speed Limit: Enables setting a maximum speed for the ebike.
• USB Current Limit (D13U only): The D13U model includes a USB port with a 1A current limit for charging external devices.

The display receives speed values from the vehicle speed monitoring device and the speed sensor, which then communicates with the controller to adjust motor speed. The display also feeds back motor speed information.

Usage Features

The D13/U display features a simple user interface with three buttons: Plus, Minus, and On/Off.

Switching On/Off: To turn on the display and start the ebike system, press and hold the On/Off key for 1 second. To turn off the system, press and hold the On/Off key for 2 seconds. When off, the display consumes minimal power (less than 2µA leakage current).

Controlling Lights and Backlights: In the power-on state, a long press of the On/Off button for 2 seconds will turn on the headlights and turn off the instrument backlight. Another long press for 2 seconds will turn off the headlights and turn on the instrument backlight.

Adjusting Pas Level and Walking Assistant Mode:

• Pas Level: In the power-on state, click the Plus or Minus button to switch between power-assisted gear positions, thereby changing the motor output power. The default output power range is 0-5 pas or 0-9 pas, which is adjustable in the settings.
• Walking Assistant Mode: Press and hold the Minus button to activate Walking Assistant mode. In this mode, the pas level becomes 0, providing low-speed assistance. Releasing the Minus button exits this mode and returns to the previous pas level.

Display Information Switching: The total mileage, single mileage, riding time, maximum speed, and average speed can be switched and displayed. In the power-on state, short press the On/Off key for 0.5 seconds to cycle through ODO -> TRIP -> TIME -> MAX -> AVG -> ODO. The display defaults to the interface shown before the last shutdown.

Resetting Trip Information: In the power-on state, pressing the Plus and Minus keys simultaneously for more than 3 seconds on any interface will reset the information in the TRIP, TIME, MAX, and AVG interfaces to zero.

Default Settings: To access default settings, ensure the ebike is stationary (speed is 0) and press and hold the On/Off key for 10 seconds to enter the password input interface.

• Password Input: Use the Plus key to cycle through digits (0-9) and the Minus key to switch between digit positions (Left -> Right -> Left). The fixed password is 6262. After entering the correct password, press the On/Off key for 0.5 seconds to enter the menu selection interface. If the password is incorrect, it returns to the main interface. The display remembers the last correctly entered password, so subsequent entries might not require re-entering it unless the power is turned off or an incorrect password is entered.
• Setting Max Pas: Within the menu, use the Minus button to select the maximum pas (5th or 9th gear). Press the On/Off key for 0.5 seconds to save and exit.
• Setting Wheel Size: Select from wheel diameters 16, 18, 20, 22, 24, 26, 27.5, 28 using the Plus and Minus keys. This ensures accurate speed and mileage. Press the On/Off key for 0.5 seconds to save and exit.
• KM/Mile Switching: Enter the unit switching interface and use the Minus key to switch between kilometers and miles. Press the On/Off key for 0.5 seconds to save and exit.
• Speed Limit: Adjust the limit speed using the Plus and Minus keys. The default speed limit is 25 KM/H. Press the On/Off key for 0.5 seconds to save and exit.

If no operations are performed in the setting interfaces for 10 seconds, the dashboard will automatically return to the main interface.

Maintenance Features

Error Code Display: If the ebike control system fails, the display will automatically show a flashing error code and stop normal operation. The fault must be eliminated to exit the error display interface and resume normal function. The manual provides a detailed error code definition table for troubleshooting.
