5. Configuración e instalación
The controller is designed for easy installation with clear wiring identification. It is specifically for 250W brushless motors and compatible with KT series communication protocols.
5.1 Wiring Identification
Carefully identify each wire according to its color and function before connecting. Refer to the diagram below for visual guidance.

Figure 5.1: Detailed wiring diagram for the controller connections.
- Black Long Wire: Connects to the Motor Wire.
- Red and Black Single Big Wire: Connects to the Power Cord (Battery).
- Red, Blue, Black, Green and Yellow Five Wire: These typically connect to the display/meter, throttle, and other accessories. Refer to your specific e-bike system's wiring for exact connections.
- Otros conectores:
- Motor: Se conecta al motor.
- Acelerador: Connects to the throttle handle.
- Mango de freno: Connects to the brake levers.
- Power Off Brake Handle: Connects to the power-off brake signal.
- Assist Sensor (magnetoelectricity): Se conecta al sensor de asistencia del pedal.
- Light Line: Connects to the bicycle lights.
- Fuente de alimentación: Entrada de energía principal desde la batería.
- Metro: Connects to the display unit.
5.2 pasos de instalación
- Desconectar la energía: Ensure the electric bicycle's battery is disconnected before starting any wiring.
- Controlador de montura: Securely mount the controller in a protected location on your bicycle, ensuring good airflow for heat dissipation.
- Conectar el motor: Connect the Black Long Wire from the controller to the corresponding motor wire.
- Conecte la electricidad: Connect the Red and Black Single Big Wire to your e-bike battery's power output. Ensure correct polarity (Red to positive, Black to negative).
- Conectar accesorios: Connect the remaining wires (throttle, brake, display, assist sensor, light line) according to the wiring diagram and your e-bike's specific components. Match connectors carefully.
- Conexiones seguras: Verifique nuevamente todas las conexiones para verificar que estén bien ajustadas y que el aislamiento sea adecuado.
- Sistema de prueba: Reconnect the battery and perform a low-speed test in a safe environment to ensure all functions (throttle, braking, display) are working correctly.
6. Instrucciones de funcionamiento
Once properly installed, the plplaaoo Sine Wave Controller provides stable and responsive control for your electric bicycle.
- Encendido: Turn on your electric bicycle's main power switch. The display (if connected) should illuminate.
- Control de velocidad: Use the throttle to control the motor speed. The controller provides sensitive speed regulation based on your input (1-4.2V).
- Frenado: Activating the brake levers will send a low-level signal to the controller, initiating sensitive braking and cutting motor power for safety.
- Asistencia al pedaleo: If an assist sensor is connected, the controller will provide motor assistance based on your pedaling input.
- Vol bajotagy Protección: The controller features built-in low voltage protection (DC 30/40 ± 0.5V) to prevent over-discharge of your battery. When the battery voltage drops below this threshold, the controller will reduce or cut power to protect the battery.
7. Mantenimiento
Regular maintenance helps ensure the longevity and optimal performance of your controller:
- Mantener limpio y seco: Periodically clean the exterior of the controller with a dry cloth. Avoid using water or cleaning solutions directly on the unit. Ensure it remains dry and free from moisture.
- Inspeccionar las conexiones: Revise periódicamente todas las conexiones de cables para garantizar que estén seguras y libres de corrosión o daños. Las conexiones sueltas pueden provocar un funcionamiento intermitente o fallos en los componentes.
- Evite el daño físico: Protect the controller from impacts or physical damage. While durable, excessive force can compromise its internal components.
- Disipación de calor: Ensure the controller's mounting location allows for adequate airflow to facilitate heat dissipation. Do not cover the controller with insulating materials.
