5. Nastavení a instalace
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 Identifikace zapojení
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.
- Další konektory:
- Motor: Connects to the motor.
- Škrticí klapka: Connects to the throttle handle.
- Rukojeť brzdy: Connects to the brake levers.
- Power Off Brake Handle: Connects to the power-off brake signal.
- Assist Sensor (magnetoelectricity): Connects to the pedal assist sensor.
- Light Line: Connects to the bicycle lights.
- Napájení: Hlavní napájení z baterie.
- Metr: Connects to the display unit.
5.2 kroky instalace
- Odpojit napájení: Ensure the electric bicycle's battery is disconnected before starting any wiring.
- Montážní ovladač: Securely mount the controller in a protected location on your bicycle, ensuring good airflow for heat dissipation.
- Connect Motor: Connect the Black Long Wire from the controller to the corresponding motor wire.
- Připojte napájení: 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).
- Připojení příslušenství: 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.
- Zabezpečená připojení: Double-check all connections for tightness and proper insulation.
- Testovací systém: Reconnect the battery and perform a low-speed test in a safe environment to ensure all functions (throttle, braking, display) are working correctly.
6. Návod k obsluze
Once properly installed, the plplaaoo Sine Wave Controller provides stable and responsive control for your electric bicycle.
- Zapnutí: Turn on your electric bicycle's main power switch. The display (if connected) should illuminate.
- Ovládání rychlosti: Use the throttle to control the motor speed. The controller provides sensitive speed regulation based on your input (1-4.2V).
- brzdění: Activating the brake levers will send a low-level signal to the controller, initiating sensitive braking and cutting motor power for safety.
