Testing and Adjusting the Autopilot Configuration 1. Drive the boat in one direction with the autopilot engaged (heading hold). The boat should not oscillate significantly; however, a small amount of oscillation is normal. 2. Turn the boat in one direction using the autopilot and observe the behavior. The boat should turn smoothly, not too quickly or too slowly. When you turn the boat using the autopilot, the boat should approach and settle on the desired heading with minimal overshoot and oscillation. 3. Select an option: • If the boat turns too quickly or too sluggishly, adjust the autopilot acceleration limiter (page 12). • If the heading hold oscillates significantly or the boat does not correct when turning, adjust the autopilot gain (page 12). • If the boat turns smoothly, the heading hold oscillates only slightly or not at all, and the boat adjusts the heading correctly, proceed to step 5. 4. Repeat steps 2 and 3 until the boat turns smoothly the heading hold oscillates only slightly or not at all, and the boat adjusts the heading correctly. 5. For planing vessels, repeat steps 1-4 at faster speeds (page 12). Adjusting the Acceleration Limiter Settings NOTE: When you manually adjust the acceleration limiter, make relatively small adjustments. Test the change before making additional adjustments. 1. Turn on the GHP 10V using the advanced configuration procedure (page 12). 2. On the GHC 20V, select Menu > Setup > Dealer Autopilot Configuration > Autopilot Tuning > Acceleration Limiter. 3. Select an option: • Increase the setting if the autopilot turns too quickly, • Decrease the setting if the autopilot turns too slowly. 4. Test the autopilot configuration. 5. Repeat steps 2 and 3 until the GHP 10V performance is satisfactory. Adjusting the Autopilot Gain Settings NOTE: When you manually adjust the rudder gain (or counter gain), make relatively small adjustments, and adjust only one value at a time. Test the change before making additional adjustments. 1. Enable the advanced configuration procedure (page 12). 2. On the GHC 20, select Menu > Setup > Dealer Autopilot Configuration > Autopilot Tuning > Rudder Gains. 3. Select an option: • Select Low Speed or High Speed and use the arrows on the GHC 20 to adjust how tightly the rudder holds the heading and makes turns at low speed or high speed. If you set this value too high, the autopilot may be overactive, attempting to constantly adjust the heading at the slightest deviation. An overactive autopilot can cause excess wear and tear on the drive unit, and drains the battery at a faster-thannormal rate. • Select Low Speed Counter or High Speed Counter to adjust how tightly the rudder corrects the turn overshoot. If you set this value too high, the autopilot can overshoot the turn again when attempting to counter the original turn. 4. Test the autopilot configuration. 12 5. Repeat steps 2 and 3 until the GHP 10V performance is satisfactory. Advanced Configuration Procedure Advanced configuration options are not available on the GHC 20 under normal conditions. To access the advanced configuration settings of the GHP 10V, enable the advanced configuration procedure. Enabling the Advanced Configuration Procedure 1. From the heading screen, select Menu > Setup > System > System Information. 2. Press and hold the center soft key ➊ for 5 seconds. Dealer Mode appears. ➊ 3. Press Back > Back. If the option for Dealer Autopilot Configuration is available on the Setup screen, the advanced configuration procedure is enabled. Advanced Configuration Settings You can run the Autotune automated configuration process, calibrate the compass, and define north on the GHP 10V through the GHC 20 without running the wizards. You can also define most settings individually, without running the configuration processes. Manually Running the Automated Configuration Procedures 1. Enable the advanced configuration procedure (page 12). 2. From the Heading screen, select Menu > Setup > Dealer Autopilot Configuration > Automated Setup. 3. Select Autotune, Calibrate Compass, or Set North. 4. Follow the on-screen instructions. Manually Running the Sea Trial Wizard The Sea Trial Wizard allows you to quickly define all of the important configuration settings on the GHP 10V. After running the wizard, if you do not feel the GHP 10V is working correctly, you can run the wizard again at any time. To access the wizard, enable the advanced configuration procedure (page 12). Manually Defining Individual Configuration Settings 1. Enable the advanced configuration procedure (page 12). 2. From the Heading screen, select Menu > Setup > Dealer Autopilot Configuration. 3. Select the a setting category. 4. Select a setting to configure. Descriptions of each setting are available in the appendix (page 15). 5. Configure the value of the setting. NOTE: Configuring certain settings in the dealer autopilot configuration procedure may require you to modify other settings. Review the GHP 10V Configurations Settings section (page 15) prior to modifying any settings. GHP 10V Installation Instructions
