Figure 2: Wiring Diagram for Electric Slip Ring Connections.
- Preparation: Disassemble the tank turret and access the main control board and existing wiring. Identify the corresponding connection points on your tank's main board.
- Main Connection: Connect the larger multi-pin connector of the slip ring to the designated port on your tank's main control board. This is typically where the turret's main wiring harness connects.
- Auxiliary Connections: Refer to Figure 2 for specific auxiliary connections. The slip ring provides dedicated ports for various tank functions:
- CN4: Barrel Lifting Gearbox
- CN10: BB Shooting Unit
- CN6: Tank Recoil
- CN16: Infrared Receiver
- CN15: Infrared Emitting Lamp
- LED5: Machine Gun Light
- FPV: First-Person View (if applicable)
- Secure Installation: Once all connections are made, carefully route the wiring to prevent pinching or interference with moving parts. Secure the slip ring within the tank's turret mechanism, ensuring it can rotate freely.
- Testing: Before reassembling the tank, perform a preliminary test to ensure all functions (turret rotation, barrel movement, shooting, lights, etc.) operate correctly.
Operating Instructions
Once correctly installed, the electric slip ring operates seamlessly with your Heng Long TK7.0 RC tank's existing control system. Its primary function is to allow the turret to rotate continuously in a full 360-degree circle without any limitations imposed by tangled wires. Operate your tank as usual, and the slip ring will manage the electrical connections for all turret-mounted functions during rotation.
Maintenance
- Regular Inspection: Periodically inspect the slip ring and its connections for any signs of wear, damage, or loose wiring.
- Cleaning: Keep the area around the slip ring free from dust, dirt, and debris, which could impede smooth rotation or affect electrical contacts. Use a soft, dry brush or compressed air for cleaning.
- Avoid Over-stress: Do not force the turret to rotate if it encounters resistance, as this could damage the slip ring or the turret mechanism.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Turret does not rotate or rotates intermittently. | Loose or incorrect main connection; damaged slip ring; obstruction in turret mechanism. | Check the main multi-pin connector. Ensure no wires are pinched. Inspect the slip ring for visible damage. Clear any obstructions. |
| Specific turret function (e.g., BB shooting, lights) not working. | Loose or incorrect auxiliary connection (CN4, CN10, etc.); faulty component. | Verify the specific auxiliary connection according to Figure 2. Check polarity. Test the individual component if possible. |
| Wires tangling despite slip ring installation. | Incorrect installation of slip ring; wires not properly routed. | Re-check slip ring mounting and ensure it is positioned to allow free rotation. Reroute internal wiring to prevent interference. |
User Tips
- This slip ring is specifically designed for RC Tanks, ensuring robust performance for continuous turret rotation.
- Always double-check your tank's model (TK7.0) before purchasing and installing to ensure compatibility.
