Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your OSCULATI Lewmar Integra 12V Autopilot Actuator. Please read this manual thoroughly before attempting any installation or operation.
The Lewmar Integra 12V Autopilot Actuator is designed to provide reliable steering control for marine vessels when integrated with a compatible autopilot system. It operates on a 12V DC power supply.
Safety Information
WARNING:
- Always disconnect power before performing any installation or maintenance.
- Ensure all electrical connections are secure and properly insulated to prevent short circuits and corrosion.
- Installation should be performed by qualified personnel familiar with marine electrical systems.
- Do not operate the actuator if it shows signs of damage.
Product Overview
The OSCULATI Lewmar Integra 12V Autopilot Actuator is a critical component of a marine autopilot system. It translates electrical signals from the autopilot course computer into mechanical movement to steer the vessel.

Figure 1: Lewmar Integra 12V Autopilot Actuator. This image shows the main unit of the actuator, typically including the motor housing and output shaft.
Key components typically include:
- Actuator Body: Houses the motor and gearing.
- Output Shaft: Connects to the vessel's steering mechanism.
- Electrical Connectors: For power and control signals.
Setup and Installation
Proper installation is crucial for the performance and longevity of the autopilot actuator.
- Mounting Location: Select a dry, protected location near the steering quadrant or tiller arm, ensuring sufficient space for movement and access. The actuator should be mounted securely to a rigid surface.
- Mechanical Connection: Connect the actuator's output shaft to the vessel's steering mechanism (e.g., tiller arm, steering quadrant) using appropriate linkages. Ensure there is no binding or excessive play.
- Electrical Wiring:
- Connect the 12V DC power supply to the actuator's power terminals. Observe correct polarity (+ and -).
- Connect the control cables from the autopilot course computer to the actuator's control terminals as per the autopilot system's instructions.
- Use marine-grade wiring and connectors.
- Initial Check: After installation, manually move the rudder to its full port and starboard positions to ensure the actuator and linkages move freely without obstruction.
Refer to your autopilot course computer manual for specific wiring diagrams and calibration procedures.
Operating Instructions
The Lewmar Integra 12V Autopilot Actuator operates under the command of a compatible autopilot course computer. It does not have direct user controls.
- Power On: Ensure the vessel's main power and the autopilot system are switched on.
- Autopilot Engagement: Engage the autopilot system according to its specific operating instructions. The actuator will then respond to commands from the course computer to maintain the set course.
- Disengagement: Disengage the autopilot system when manual steering is required or in emergency situations.
Always monitor the vessel's steering and be prepared to take manual control, especially in challenging conditions.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your actuator.
- Monthly Check:
- Inspect all mechanical connections for tightness and wear.
- Check electrical connections for corrosion or damage.
- Ensure the actuator moves freely without excessive noise or resistance.
- Annual Check:
- Lubricate moving parts as recommended by the manufacturer (if applicable).
- Clean the exterior of the actuator, removing any salt residue or dirt.
- Inspect the wiring for chafing or degradation.
CAUTION:
Do not attempt to open the sealed actuator unit. Internal repairs should only be performed by authorized service technicians.
Troubleshooting
This section provides solutions to common issues. For more complex problems, consult a qualified marine technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not respond | No power; Loose electrical connections; Faulty course computer signal. | Check 12V power supply; Verify all wiring connections; Consult autopilot course computer manual. |
| Excessive noise or vibration | Mechanical binding; Worn linkages; Internal actuator issue. | Inspect mechanical connections for obstructions; Check for worn parts; Contact service technician if internal issue is suspected. |
| Inaccurate steering | Autopilot calibration issue; Mechanical play in steering system. | Recalibrate autopilot system; Inspect steering linkages for excessive play. |
