5. Persediaan & Pemasangan
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.
- Other Connectors:
- Motor: Connects to the motor.
- Pendikit: Connects to the throttle handle.
- Pemegang Brek: 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.
- Bekalan Kuasa: Main power input from the battery.
- meter: Connects to the display unit.
5.2 Langkah Pemasangan
- Putuskan Kuasa: Ensure the electric bicycle's battery is disconnected before starting any wiring.
- Mount Controller: Securely mount the controller in a protected location on your bicycle, ensuring good airflow for heat dissipation.
- Sambungkan Motor: Connect the Black Long Wire from the controller to the corresponding motor wire.
- Sambungkan Kuasa: 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).
- Sambung Aksesori: 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.
- Sambungan Selamat: Periksa semula semua sambungan untuk memastikan ketat dan penebat yang betul.
- Sistem Ujian: Reconnect the battery and perform a low-speed test in a safe environment to ensure all functions (throttle, braking, display) are working correctly.
6. Arahan Operasi
Once properly installed, the plplaaoo Sine Wave Controller provides stable and responsive control for your electric bicycle.
- Hidupkan kuasa: Turn on your electric bicycle's main power switch. The display (if connected) should illuminate.
- Kawalan Kelajuan: Use the throttle to control the motor speed. The controller provides sensitive speed regulation based on your input (1-4.2V).
- Brek: Activating the brake levers will send a low-level signal to the controller, initiating sensitive braking and cutting motor power for safety.
- Bantuan Pedal: If an assist sensor is connected, the controller will provide motor assistance based on your pedaling input.
- Vol. Rendahtage Perlindungan: 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. Penyelenggaraan
Regular maintenance helps ensure the longevity and optimal performance of your controller:
- Pastikan Bersih dan Kering: 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.
- Periksa Sambungan: Regularly check all wire connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or component failure.
- Elakkan Kerosakan Fizikal: Protect the controller from impacts or physical damage. While durable, excessive force can compromise its internal components.
- Pelesapan Haba: Ensure the controller's mounting location allows for adequate airflow to facilitate heat dissipation. Do not cover the controller with insulating materials.
