4. Setup

Before initial use, ensure all connections are secure and correctly polarized. Connect the ESC to your motor, receiver, and battery according to your RC boat's wiring diagram. Pay close attention to the throttle calibration procedure outlined below.

4.1. Throttle Calibration

Throttle calibration is crucial for the first-time use or whenever the transmitter (TX) is changed. Follow these steps carefully:

1. For Reverse/Bi-Directional Function:
   • Set the throttle stick on your transmitter to the neutral position.
   • Power on the ESC. After hearing a beep, move the throttle stick to the MAX position.
   • After hearing another beep, move the throttle stick to the MINIMUM position.
   • Power off the ESC, then restart it. The calibration is complete.
2. For Forward-Only Function (No Reverse):
   • Set the throttle stick on your transmitter to the MAX position.
   • Power on the ESC. After hearing a beep, move the throttle stick to the MINIMUM position.
   • After hearing another beep, power off the ESC, then restart it. The calibration is complete.

5. Operating Instructions

The ZTW Shark G2 60A SBEC ESC is designed for reliable performance in various aquatic RC applications. Ensure your motor and battery are compatible with the ESC's specifications before operation.

5.1. Applications

• Suitable for use with RC boat inrunner motors.
• Compatible with underwater thruster engines for RC bait tug boats, ROVs, and submarines.
• Applicable to any DIY project requiring a bi-directional function.

6. Maintenance

While the ZTW Shark G2 60A SBEC ESC features a full waterproof design, proper care extends its lifespan. After each use in water, rinse the ESC with fresh water to remove any salt or debris, and allow it to dry completely before storage. Regularly inspect all wiring and connectors for signs of wear or corrosion. Ensure the water-cooling system is free from obstructions.

7. Troubleshooting

• No Power/No Response: Check battery connections, ensure the battery is charged, and verify the ESC is correctly connected to the receiver.
• Motor Not Spinning: Re-perform throttle calibration. Check motor wire connections for proper phase. Ensure the motor is not seized.
• Intermittent Operation: Inspect all wiring for loose connections or damage. Check for signal interference. Ensure the BEC output is stable.
• Overheating: Verify the water-cooling system is functioning correctly and not obstructed. Ensure the motor is not overloaded or improperly geared.
• Unexpected Shutdown: This may indicate low voltage cut-off or over-temperature protection activation. Check battery voltage and ESC temperature.
