2. Key Features
- Auto Trim Tab Control: Automatically reduces bow rise and corrects listing for optimal boat performance.
- Manual Tab Control: Allows for immediate manual override and control of the trim tabs at any time.
- Trim Tab Position Indication: Provides visual feedback on the current position and activity of the trim tabs.
- "All Up" and "All Down" Buttons: Enables one-touch manual adjustments to fully retract or fully deploy the trim tabs.
- Integrated System: Includes the ATP control kit, ATP helm display, and plug-and-play waterproof connectors for simplified installation.
3. Setup and Installation
Proper installation is crucial for the optimal performance of the AutoTrim Pro system. It is recommended to consult the detailed installation guide provided with your product for specific wiring diagrams and mounting instructions. The system includes an ATP control kit, ATP helm display, and waterproof connectors designed for ease of assembly.
3.1 Wiring Considerations
- Ensure all connections are secure and waterproof.
- For boats that may be left unattended for extended periods, consider wiring the system to a dedicated switch. This allows the unit to be completely powered off, preventing potential battery drain, as the system may draw a small amount of power even when inactive.
- Verify that all necessary cables and adapters are present before beginning installation. If any components appear to be missing, contact Bennett Marine support.
3.2 Initial Programming and Calibration
The unit requires precise setup and programming to establish the correct level and running attitude for your specific vessel. Follow the calibration instructions in the full manual carefully to ensure accurate automatic trim adjustments.
4. Operating Instructions
4.1 Automatic Trim Tab Control
To engage automatic control, ensure the boat is on plane. You may initially set the tabs to "All Down" during acceleration, then switch to "Auto" mode once the desired speed is reached. The system will then continuously monitor and adjust the trim tabs to maintain optimal boat attitude, reducing bow rise and correcting any listing.
4.2 Manual Trim Tab Control
At any point, you can override the automatic system and take manual control of the trim tabs. Refer to the helm display for specific buttons or controls to switch between automatic and manual modes. Manual control allows for precise adjustments as needed.
4.3 Trim Tab Position Indication
The ATP helm display provides real-time indication of your trim tab positions. This visual feedback helps you understand the system's activity and make informed manual adjustments if necessary.
4.4 One-Touch Adjustments ("All Up" and "All Down")
Dedicated "All Up" and "All Down" buttons allow for quick, full retraction or deployment of the trim tabs. These are useful for initial planing or when docking.
5. Maintenance
The Bennett AutoTrim Pro system is designed for durability in marine environments. Regular maintenance includes:
- Visual Inspection: Periodically check all wiring and connections for signs of wear, corrosion, or damage.
- Cleaning: Keep the helm display and control unit clean and free of salt residue or debris. Use a soft, damp cloth.
- Hydraulic System Check: Ensure the associated hydraulic trim tab system is properly maintained according to its own manual, as the AutoTrim Pro relies on its functionality.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not powering off / Battery drain | Unit remains powered on even when boat is off. | Wire the AutoTrim Pro to a switched power source to allow for complete power disconnection when not in use. |
| Incorrect automatic trim behavior (e.g., persistent listing) | Improper initial calibration or setup. | Review and repeat the initial programming and calibration steps as outlined in the full installation manual. Ensure the boat is in a level attitude during calibration. |
| System not functioning / Missing components | Missing critical wiring harness or adapter. | Verify all included components against the packing list. Contact Bennett Marine customer support for assistance with missing parts or compatibility issues. |
