The DZ40 is an LCD display designed for EN15194 electric bicycles. It features a simple and thin design, intended for installation on the left handlebar, and can be used in conjunction with a middle display. The display utilizes a high-brightness white nixie tube for clear visibility.

Function Description:

The DZ40 display provides essential information and control for electric bicycle operation. Key functions include:

• Speed Display: Shows real-time speed.
• Gear Control: Allows control over 0-5 gears, with a default setting of 0-5.
• Battery Indication: Features a six-level battery indicator, showing levels 1-5 and providing an under-voltage prompt (indicated by one light flashing).
• Walk-Assist Function: Enables a walk-assist mode.
• Headlight Indication: Displays the headlight status (requires controller support).
• Fault Code Indication: Shows fault codes to help diagnose issues.
• User Settings: Allows users to adjust various parameters, including unit settings (metric KM/imperial MI), wheel diameter information, and speed limit information. Battery voltage is a fixed display item.

Important Technical Specifications:

• Power Supply: DC 24V/36V/48V.
• Rated Current: 18mA/36V.
• Shutdown Leakage Current: < 1uA.
• Display Type: White digital tube display.
• Communication Mode: UART (default).
• Working Temperature: -20°C ~ 60°C.
• Storage Temperature: -30°C ~ 80°C.
• Waterproof Level: IP65.
• Housing Material: ABS.
• Upper Housing Window Material: Brown PC with high hardness.
• Installation: Designed for standard handle pipe size φ 22.2, fixed with an M3 inner hexagon screw. Locking torque is 0.8N.m.

Usage Features:

• Four Buttons: The display is equipped with four buttons for easy operation: a switch on/off button, a function key, an adjustment key+ (for the upper part of the display area), and an adjustment key- (for the lower part of the display area).
• Power On/Off: To turn on, press the switch on/off key for 2 seconds when the display is off. To turn off, long-press the switch on/off key for 2 seconds in the power-on state. The display automatically turns off after 5 minutes of inactivity (if speed is 0).
• Power Shift Switching: Press the adjustment key+ or adjustment key- to switch between assist gears (0/low/medium/high).
• Assist Implementation: Press and hold the adjustment key- button for 2 seconds to enter boosting state; release it to exit.
• Headlight Control: Press and hold the function key for 1 second to turn on headlights (if supported by the controller), which also dims the display. Press again for 1 second to turn off headlights and restore display brightness.
• User Settings Access: Within 10 seconds of startup, press and hold the function key for 2 seconds to enter the user setting interface. Long-press the function key for 2 seconds to exit and save settings. If no operation occurs for 10 seconds in the setting interface, the display reverts to normal riding state without saving.
• Unit Setting: Allows switching between metric (KM) and imperial (MI) units. The factory default is KM.
• Wheel Diameter Information: Users can view wheel diameter information (e.g., 700C, 27.5).
• Speed Limit Information: Displays the speed limit (default is 25 km/h).
• Battery Voltage Check: Shows the collected battery voltage (two digits, decimal places rounded off).
• Battery Display: When battery power is normal, a 5-segment LCD displays power, and the outer frame lights up. When exhausted, the 5-segment LCD is extinguished, and the outer frame flashes, indicating immediate charging is needed.

Maintenance Features:

• UART Communication Interface: Provides a convenient interface for maintenance services.
• Fault Code Display: The display shows a fault icon and flashing fault code (e.g., E30 for communication failure) to help identify issues.
• Fault Code Definition: The device defines ERROR 30 for communication failure, which means the display cannot receive data from the controller or receives incorrect data.
• Troubleshooting for E30:
  1. Check if TX and RX communication lines are connected correctly.
  2. Check if the harness and connector are loose or broken.
  3. Verify if the display communication protocol matches.
• Wiring Definition: A standard connector wiring definition table is provided, detailing the function of each line (Red: VCC, Blue: Kp, Black: GND, Green: RX, Yellow: TX). Note that for waterproof plug-ins, lead colors may not be visible in the harness.

General Attention Points:

• Always ensure safety during use.
• Do not plug or unplug the display while the power supply is active.
• Avoid using the device in harsh environments such as heavy rain, heavy snow, or direct exposure.
• If the display cannot be used normally, it should be repaired as soon as possible.
