4. Setup
4.1 Mounting
Mount the controller in a location that is protected from direct exposure to water, excessive dust, and mechanical impact. Ensure adequate airflow around the unit for proper heat dissipation. Use appropriate fasteners to secure the controller firmly to a stable surface.
4.2 Wiring Connections
Refer to the vehicle's specific wiring diagram for detailed connection instructions. The general connections are as follows:
- B+ Terminal: Connect to the positive (+) terminal of the battery pack.
- B- Terminal: Connect to the negative (-) terminal of the battery pack.
- U, V, W Terminals: Connect to the corresponding phase wires of the brushless permanent magnet motor. Ensure correct phase sequence.
- J1, J2, J3 Connectors: These are for control signals, sensors (e.g., Hall sensors), throttle input, and communication. Consult the vehicle's wiring diagram for specific pin assignments and functions.
Use appropriately sized cables and terminals to handle the maximum current draw. All connections must be tight and free from corrosion.
4.3 Initial Power-Up
After all connections are made and verified, connect the battery power. Observe any indicator lights on the controller (if present) for initial status. Do not operate the motor immediately. Perform a functional check of all safety interlocks and control inputs before full operation.
5. Operating Instructions
The COKYIS 1226BL-4151 controller operates in conjunction with the vehicle's control system (e.g., throttle, direction switch, brake). Ensure all vehicle controls are functioning correctly before operating.
- Power On: Turn on the vehicle's main power switch. The controller will perform a self-test.
- Throttle Control: Gradually apply the throttle to initiate motor movement. The controller will regulate motor speed based on the throttle input.
- Direction Control: Use the vehicle's direction switch (forward/reverse) as required.
- Braking: The controller supports regenerative braking and/or electromagnetic braking depending on the vehicle's configuration.
Always operate the vehicle within its design limits and follow all manufacturer guidelines for the vehicle itself.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of the controller.
- Cleaning: Periodically clean the exterior of the controller to remove dust and debris. Use a dry, soft cloth. Do not use solvents or abrasive cleaners. Ensure no moisture enters the unit.
- Connection Inspection: Regularly inspect all wiring connections for tightness, signs of corrosion, or damage. Re-tighten loose connections and replace any damaged wiring.
- Environmental Check: Ensure the mounting environment remains suitable, free from excessive heat, moisture, or vibration.
- Ventilation: Verify that cooling fins (if present) are not obstructed to allow for proper heat dissipation.
7. Troubleshooting
If the controller or motor is not functioning as expected, perform the following basic checks:
| Symptom | Possible Cause | Action |
|---|---|---|
| Motor does not run | No power to controller, faulty throttle, motor wiring issue, safety interlock engaged. | Check battery voltage, verify all power and control connections, inspect throttle operation, ensure all safety switches are disengaged. |
| Intermittent operation | Loose connections, overheating, sensor issue. | Inspect all wiring for loose connections. Ensure adequate ventilation. Check motor sensor connections. |
| Controller is hot | Overload, insufficient cooling, short circuit. | Reduce load, improve ventilation, check for short circuits in motor or wiring. |
If troubleshooting steps do not resolve the issue, contact a qualified service technician or the manufacturer for further assistance.
