Operating Instructions

Once installed, the system is ready for operation. Familiarize yourself with the display and throttle functions before riding.

KT LCD5 Display Panel

The KT LCD5 display panel is specifically designed for KT series controllers and provides real-time information and control over your electric bike's system.

• Power On/Off: Press and hold the power button on the display to turn the system on or off.
• Information Display: The display shows various parameters such as current speed, battery level, assist level, trip distance, and total distance.
• Assist Level Adjustment: Use the up/down buttons to cycle through different pedal assist levels (PAS). Higher levels provide more motor assistance.
• Settings: Refer to the separate KT LCD5 Display Panel Manual for detailed instructions on accessing and adjusting advanced settings.

Thumb Throttle

The thumb throttle allows for manual speed control, independent of pedal assist.

• Acceleration: Gently press the thumb lever to engage the motor and accelerate. The further you press, the more power is delivered.
• Deceleration: Release the thumb lever to reduce power and decelerate.
• Safety: Always use the throttle responsibly and be aware of your surroundings.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your electric motor controller kit.

• Cleaning: Keep the controller, display, and throttle clean and free from dust, dirt, and moisture. Use a soft, damp cloth for cleaning. Do not use harsh chemicals or abrasive materials.
• Moisture Protection: Avoid exposing the components to heavy rain or submerging them in water. While designed for outdoor use, excessive moisture can damage electronics.
• Connection Inspection: Periodically inspect all electrical connections for signs of corrosion, wear, or looseness. Tighten any loose connections and replace damaged wiring immediately.
• Heat Dissipation: Ensure the controller's aluminum alloy casing, which acts as a heatsink, is not obstructed. Good airflow is essential for proper heat dissipation.
• Cable Management: Ensure all cables are neatly routed and secured to prevent snagging or damage during riding.

Troubleshooting

This section addresses common issues you might encounter. For more detailed troubleshooting, refer to the specific manuals for the KT LCD5 display and controller.

• System Not Powering On:
  • Check the battery connection and ensure the battery is charged.
  • Verify that the display panel is correctly connected to the controller.
  • Ensure the power button on the display is pressed and held sufficiently.
• Motor Not Responding:
  • Check all motor phase wire connections and Hall sensor connections.
  • Verify the thumb throttle connection and functionality.
  • Ensure the brake levers are not engaged (some systems have cut-off switches).
  • Check for error codes on the LCD display.
• Inconsistent Power Assist:
  • Inspect the power assist magnetic point sensor and magnet for proper alignment and cleanliness.
  • Ensure the sensor cable is securely connected to the controller.
• Display Not Showing Correct Information:
  • Ensure all display connections are secure.
  • Refer to the KT LCD5 Display Panel Manual for calibration or setting adjustments.
