1.3 Connecting the Display

The P3C display uses a UART 2 communication protocol. Ensure your e-bike controller is compatible. The display comes with various connector types to suit different e-bike conversion kits. Inappropriate interface replacement may affect the normal use of the display screen.

2. Operating Instructions

The P3C LCD Display Meter provides essential information and controls for your e-bike. It features a horizontal mid-mounted VA color LCD display for vivid and dynamic data presentation.

2.1 Display Overview

Key display areas include:

• Battery Indicator: Shows current battery charge level.
• Multifunctional Display Area: Displays various data such as voltage (VOL).
• Headlight Indicator: Shows if the headlight is on.
• PAS (Pedal Assist System) Level: Indicates the current assist level (e.g., 5 PAS Mode).
• Speed: Current riding speed (KM/H or MPH).
• Mileage: Displays Trip (ODO) or Total Mileage (KM).

2.2 Functions and Controls

The display features three buttons (+ , Power, -) for easy navigation and control:

• Battery Indicators: Monitor your e-bike's power.
• Walk Mode: Activates a low-speed assist for walking the bike.
• PAS Level Adjustment: Cycle through different pedal assist levels (e.g., 5 PAS modes).
• Speed Display: View your current speed.
• Trip/ODO: Toggle between trip distance and total odometer readings.
• Trip Time: Displays the duration of your current ride.
• Mile/KM Conversion: Switch between metric and imperial units.
• Error Warning: Alerts you to system faults.
• Headlight Control: Turn your e-bike's headlight on or off.
• Boost Function: Provides a temporary power boost.
• USB Charging: The display includes a USB interface (5V/500mA) for emergency charging of mobile phones or other small devices.

3. Maintenance

To ensure the longevity and optimal performance of your P3C Electric Bike LCD Display Meter, follow these maintenance guidelines:

• Cleaning: Use a soft, damp cloth to wipe the display screen and body. Avoid abrasive cleaners, solvents, or harsh chemicals that could damage the screen or casing.
• Protection: While the display has an IP65 rating (dust tight and protected against water jets), avoid submerging it in water or exposing it to heavy rain for extended periods.
• Storage: When not in use for extended periods, store the e-bike and display in a dry, temperate environment.
• Cable Inspection: Periodically check all cables and connectors for any signs of wear, damage, or loose connections.

4. Troubleshooting

This section addresses common issues you might encounter with your P3C Electric Bike LCD Display Meter.

4.1 E10 Error Code

If the display shows "E10" after connecting, it indicates a communication issue. There are two primary reasons for this error:

1. Incompatible Communication Protocol: The communication protocol between the display and your e-bike's controller may be incompatible. Ensure both components use the UART 2 protocol.
2. Vehicle System Malfunction: The e-bike's overall condition might be poor, affecting components such as the boost controller, throttle (knob), or motor. These issues can disrupt communication with the display. Inspect these components for proper function and connection.

If you encounter the E10 error, first verify protocol compatibility. If compatible, check all related wiring and components of your e-bike system.

4.2 General Display Issues

• Display Not Turning On: Check the power connection to the display and ensure your e-bike's battery is charged and turned on.
• Incorrect Readings: Ensure all connections are secure. If speed or mileage readings are incorrect, check the speed sensor and its magnet on your wheel.

6. User Tips

Here are some helpful tips based on common user inquiries:

• Compatibility Check: Before purchasing or installing, always verify that the P3C display's UART 2 communication protocol and voltage (24V/36V/48V/60V) are compatible with your specific e-bike model and controller. Some e-bikes, like certain Giant/Yamaha models or Eskute Wayfarer, may use different protocols or wiring.
• Connector Type: Pay close attention to the connector type (e.g., 5PIN, 6PIN, SM 5pin, SM 6pin, SM 7PIN) to ensure it matches your e-bike's wiring harness.
• E10 Error: If you encounter an E10 error, double-check the communication protocol and inspect your e-bike's boost controller, throttle, and motor for any issues that might prevent proper communication with the display.
