4. Setup
Follow these steps to set up your CR40EP Lipo Waterproof Controller:
- Mounting the Controller: Securely mount the controller in your RC vehicle using appropriate mounting tape or screws. Ensure it is placed in a location that allows for adequate airflow for cooling, if applicable, and is protected from direct impact.
- Connecting to Motor: Connect the three motor wires from the controller to your brushless motor. The order of connection may affect motor rotation direction; if the motor spins in the wrong direction, swap any two of the three wires.
- Connecting to Receiver: Plug the signal cable (usually a three-wire servo connector) from the controller into the throttle channel (typically channel 2) of your RC receiver.
- Connecting Battery: Connect your compatible battery pack (2-3S LiPo or 5-9 cell NiCd/NiMH) to the controller's battery input. Ensure correct polarity.
- Transmitter Setup: Turn on your RC transmitter and ensure the throttle trim is centered and the throttle EPA (End Point Adjustment) or ATV (Adjustable Travel Volume) is set to 100% for both forward and reverse.
- Calibration (if required): Some controllers require calibration with the transmitter's throttle stick. Refer to your RC vehicle's specific instructions or the controller's detailed manual for calibration procedures if the controller does not respond correctly.
Figure 1: The Jamara CR40EP Lipo Waterproof Controller. This image shows the compact black controller unit with cooling fins, featuring a label indicating "Speedregler CR40EP Lipo Waterproof" and "Rev./Brake Art.Nr. 081449". Wires extend from the unit: a thin three-wire servo cable (white, red, black) for receiver connection, and three thicker wires (yellow, red, blue) with bullet connectors for motor connection.
5. Operating
Once the controller is properly set up, follow these general operating guidelines:
- Power On Sequence: Always turn on your RC transmitter first, then connect the battery to the controller.
- Throttle Control: Use the throttle stick on your transmitter to control the speed and direction of your RC vehicle. Pushing forward typically engages forward motion, pulling back engages reverse (after a brief neutral pause), and returning to center is neutral.
- Braking: The controller features a reverse/brake function. Applying reverse throttle from a forward motion will typically engage braking.
- Waterproof Feature: While waterproof, avoid submerging the controller for extended periods or in corrosive liquids. Always dry the controller thoroughly after exposure to water.
- Power Off Sequence: Disconnect the battery from the controller first, then turn off your RC transmitter.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your controller:
- Cleaning: Regularly clean the exterior of the controller to remove dirt, dust, and debris. Use a soft, dry brush or cloth. For stubborn dirt, a slightly damp cloth can be used, ensuring the controller is completely dry before next use.
- Inspecting Wires and Connectors: Periodically check all wires and connectors for signs of wear, fraying, or corrosion. Replace any damaged components immediately.
- Storage: Store the controller in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Battery Care: Always follow the manufacturer's guidelines for battery charging, discharging, and storage to prevent damage to both the battery and the controller.
7. Troubleshooting
If you encounter issues with your controller, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on. | Battery not connected, battery discharged, incorrect polarity, faulty wiring. | Check battery connection and charge. Verify polarity. Inspect all wires for damage. |
| Motor not responding or erratic. | Incorrect motor wiring, receiver not connected, transmitter/controller not calibrated, signal interference. | Verify motor wire connections. Ensure receiver is properly connected to controller. Perform throttle calibration. Check for signal interference. |
| Motor spins in wrong direction. | Incorrect motor wire phasing. | Swap any two of the three motor wires connected to the controller. |
| Controller gets excessively hot. | Overloading, insufficient cooling, incorrect gearing. | Reduce load, ensure adequate airflow, check motor and gearing for proper setup. |
