Орнотуу кадамдары (Жалпы көрсөтмө):
- Биринчи коопсуздук: Disconnect the e-bike's battery before beginning any installation work.
- Монтаждоо: Securely mount the controller in a protected area on your e-bike, away from direct water exposure and excessive vibration. Ensure adequate airflow for cooling.
- Мотор зымдарын туташтыруу: Connect the motor phase wires (usually thicker wires) from the controller to the corresponding motor wires. Ensure correct phase matching.
- Холл сенсорунун зымдарын туташтырыңыз: Connect the Hall sensor wires (usually thinner wires) from the controller to the motor's Hall sensor connector.
- Connect Battery Wires: Connect the main power wires (red for positive, black for negative) from the controller to the e-bike battery. Double-check polarity.
- Connect Throttle/Pedal Assist Sensor (PAS): Connect the throttle and/or PAS sensor wires to their respective connectors on the controller.
- Connect Brake Levers: Connect the brake lever wires (if applicable) to the controller. This allows the motor to cut off power when brakes are applied.
- Connect Display/Control Panel: Connect the display or control panel wires to the controller.
- Акыркы текшерүү: Before reconnecting the battery, visually inspect all connections to ensure they are secure and correctly matched.
- Сыноо: Reconnect the battery and perform a low-speed test to verify proper operation.
If you are unsure about any part of the installation, consult with a qualified e-bike technician.
4. Иштөө нускамалары
Once the controller is correctly installed and powered on, it will manage the electric motor's functions based on your e-bike's input devices (throttle, pedal assist sensor, brake levers).
Operational Modes (Three Gears)
The controller supports three distinct operational modes, often referred to as 'gears' or 'power levels'. These modes typically adjust the maximum power output or speed limit of the motor. You can usually switch between these modes using a button on your e-bike's display or control panel. Consult your e-bike's specific user manual for details on how to select these modes.
- 1-режим (төмөн): Provides lower power assistance, suitable for casual riding, maximizing range, or navigating crowded areas.
- 2-режим (Орто): Offers balanced power and speed, ideal for general commuting and varied terrain.
- 3-режим (Жогорку): Delivers maximum power assistance for higher speeds, climbing steep inclines, or rapid acceleration.
Тормоз жардам
The controller features a low brake assist function. When the brake levers are engaged, the controller will cut power to the motor, ensuring safe deceleration and stopping. This function is crucial for rider safety.
5. Техникалык тейлөө
To ensure the longevity and optimal performance of your Engwe DC Motor Controller, follow these general maintenance guidelines:
- Тазалыкты сактоо: Regularly clean the exterior of the controller to prevent dust and dirt buildup, which can hinder heat dissipation. Use a dry or slightly damp кездеме. Катуу химиялык заттарды колдонбоңуз же сууга батырбаңыз.
- Байланыштарды текшерүү: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent power or damage.
- Суунун таасиринен сактаныңыз: While designed for outdoor use, avoid prolonged exposure to heavy rain or submersion in water. Water ingress can severely damage the internal electronics.
- Температураны башкаруу: Ensure the controller is mounted in a location that allows for proper heat dissipation. Avoid covering it with insulating materials during operation.
- Кесиптик текшерүү: If you notice any unusual behavior, sounds, or smells from the controller, have it inspected by a qualified technician.
