Setup and Installation

Proper installation is crucial for the safe and efficient operation of your brushless motor speed controller. It is recommended that installation be performed by a qualified technician if you are unfamiliar with electrical wiring.

Wiring Diagram Overview

The controller features a "simple structure with separate wire," indicating distinct connectors for different functions. Refer to the following general guidelines for connection. Always consult your motor and vehicle's specific wiring diagrams for precise connections.

1. Power Connection: Connect the thick red wire to the positive (+) terminal of your 48V or 72V battery and the thick black wire to the negative (-) terminal. Ensure a secure connection to prevent arcing.
2. Motor Phase Wires: Connect the three thick motor phase wires (typically yellow, green, blue) from the controller to the corresponding phase wires on your brushless motor.
3. Hall Sensor Wires (if applicable): If your motor uses Hall sensors, connect the thin Hall sensor wires (typically red, black, yellow, green, blue) from the controller to the motor's Hall sensor harness. If your motor is a "no hall motor," these connections will not be used.
4. Throttle Connection: Connect the throttle wires (typically red, black, green) to the throttle unit. Red is usually positive, black is ground, and green is the signal wire.
5. Brake Levers: Connect the brake lever wires (High/Low Electrical Level) to the corresponding brake cut-off switches on your brake levers. This allows the motor to cut power when brakes are applied.
6. Other Connections: Depending on your vehicle, there may be additional connections for display, speed sensor, anti-theft, cruise control, etc. Identify these wires carefully and connect them according to your vehicle's specific requirements.

Mounting the Controller

The controller features an aluminum alloy shell designed for heat dissipation. Mount the controller in a location that allows for adequate airflow and protects it from direct water exposure and physical damage. Use the integrated mounting brackets to secure it firmly to the vehicle frame.

Operating Instructions

Once properly installed, the controller will manage the power delivery to your motor based on your input.

• Power On: Ensure all connections are secure. Turn on the main power switch of your electric vehicle.
• Throttle Control: Gently twist the throttle to initiate motor movement. The controller provides sensitive control for smooth acceleration.
• Braking: Activating the brake levers will signal the controller to cut power to the motor, ensuring safe deceleration.
• 2-Mode Operation: The controller supports a "2-mode" operation, which typically refers to different power or speed settings. Consult your vehicle's specific interface (e.g., display unit, switch) to understand how to switch between these modes for optimal climbing or speed performance.
• Automatic Identification: The controller features 60°/120° phase angle automatic identification, meaning it can adapt to different motor types without manual configuration for phase angle.

Maintenance

To ensure the longevity and optimal performance of your Silscvtt controller, follow these maintenance guidelines:

• Regular Inspection: Periodically check all wiring connections for tightness and signs of wear or corrosion.
• Cleanliness: Keep the controller unit clean and free from dust, dirt, and moisture. Use a dry cloth for cleaning. Avoid using water or harsh chemicals.
• Heat Dissipation: Ensure the controller's mounting location allows for proper airflow. Do not cover the controller or obstruct its cooling fins.
• Avoid Overloading: Do not exceed the specified voltage (48V/72V) or power (1500W) limits of the controller. Overloading can lead to overheating and damage.
• Environmental Protection: Protect the controller from extreme temperatures, direct sunlight, and heavy rain.
