4. Setup and Installation

Proper installation is crucial for the optimal performance of your Simrad autopilot system. Follow these steps carefully.

4.1 Planning the Installation

Before beginning, plan the location for each component. Consider cable routing, accessibility for maintenance, and environmental factors.

• NAC-1 Processor: Mount in a dry, protected area, away from heat sources and strong electromagnetic fields.
• PUMP-1 Hydraulic Pump: Install close to the steering cylinder, ensuring easy access for hydraulic line connections and fluid checks.
• POINT-1 GPS Antenna: Mount in a location with a clear, unobstructed view of the sky (360 degrees horizontally, 10 degrees above the horizon). Avoid mounting near radar, VHF antennas, or other transmitting devices.

4.2 Mounting the NAC-1 Processor

1. Select a suitable mounting surface.
2. Use the provided template (if applicable) to mark drill holes.
3. Secure the NAC-1 processor using the supplied mounting hardware.

4.3 Installing the PUMP-1 Hydraulic Pump

1. Ensure the vessel's engine is off and the steering system is depressurized.
2. Mount the pump securely to a rigid surface.
3. Connect the hydraulic lines from the steering system to the pump according to the diagram in the quick start guide. Ensure all connections are tight and leak-free.
4. Bleed the hydraulic system thoroughly after installation.

4.4 Mounting the POINT-1 GPS Antenna

1. Choose a high, unobstructed location.
2. Secure the POINT-1 antenna using the provided mounting hardware.
3. Route the NMEA 2000 cable from the antenna to the NMEA 2000 backbone.

4.5 Wiring Connections

All components connect to a common NMEA 2000 network. Ensure the network is properly terminated at both ends.

• NMEA 2000 Network: Connect the NAC-1 processor, PUMP-1 pump, and POINT-1 antenna to the NMEA 2000 backbone using T-connectors.
• Power: Connect the NMEA 2000 network power cable to a fused 12V DC power source. The NAC-1 processor and PUMP-1 pump draw power from the NMEA 2000 network.
• Steering Feedback: Connect the steering feedback unit (if external, otherwise integrated) to the NAC-1 processor as per the wiring diagram.

4.6 Initial Power-Up and Configuration

1. Apply power to the NMEA 2000 network.
2. Turn on your Simrad multifunction display (MFD) or autopilot controller.
3. Follow the on-screen prompts to perform initial setup, including compass calibration, rudder response calibration, and sea trial calibration. Refer to your MFD's manual for detailed calibration procedures.

5. Operating Instructions

Once installed and calibrated, your Simrad autopilot system is ready for operation.

5.1 Basic Operation

• Power On/Off: The autopilot system powers on with the NMEA 2000 network.
• Standby Mode: Press the 'Standby' button on your controller or MFD to disengage the autopilot and take manual control.
• Auto Mode: Press the 'Auto' button to engage the autopilot and maintain the current heading.
• Heading Adjustments: Use the +/- 1 degree or +/- 10 degree buttons on your controller to adjust the heading in Auto mode.

5.2 Advanced Features

• NoDrift Mode: This mode maintains your vessel's position over ground, compensating for wind and current. Activate from your MFD.
• Waypoint Navigation: If connected to a chartplotter, the autopilot can steer to a selected waypoint or along a route. Select the waypoint/route on your MFD and engage 'Nav' mode on the autopilot.
• Turn Patterns: Access pre-defined turn patterns (e.g., U-turn, spiral turn) from your MFD for specific maneuvers.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your autopilot system.

• Cable Connections: Periodically check all NMEA 2000 and power cable connections for corrosion or looseness.
• Hydraulic Fluid: Check the hydraulic fluid level in the steering system reservoir regularly. Top up with the recommended fluid if necessary. Inspect hydraulic lines for leaks.
• Software Updates: Check the Simrad website for the latest software updates for your NAC-1 processor and POINT-1 antenna. Updates can improve performance and add new features.
• Cleaning: Clean the exterior of the NAC-1 processor and POINT-1 antenna with a damp cloth. Avoid harsh chemicals.
