When you reach page 25 of the GHP 10 Installation Instructions, refer to the notes in this document to achieve the best results with configuring and tuning the GHP 10. The Sea-Trial Wizard The Sea Trial Wizard configures the fundamental sensors on the autopilot, and it is extremely important to complete the wizard in conditions appropriate for your boat. In general, it is highly recommended to complete the Sea Trial Wizard in calm water with little or no wind. Because the nature of calm water is relative to the size and shape of your boat, be sure you choose a location where: • Your boat does not rock while sitting still or moving very slowly. • Your boat is not significantly affected by the wind. While completing the Sea Trial Wizard in calm water, it is important to observe the following: • Keep the weight on your boat balanced. DO NOT move around on the boat while completing any of the steps in the Sea Trial Wizard. • Be sure that the engines are trimmed down, and that the trim tabs are up. Planing RPM Note If you have a displacement-hull boat, there will not be a transition point for you to set. Instead, adjust the Planing RPM to the highest possible value (6000 RPM). Compass Calibration Notes Before you begin the compass calibration procedure, drive your boat in a slow, straight line, and wait for the wake generated by the previous step to pass. When you begin the procedure, turn the boat slowly clockwise, taking care to make as steady and flat a turn as possible. Turn slowly enough that the boat DOES NOT list. If you have a dual-engine boat, slowly run the port engine forward and the starboard engine in reverse to pivot on a stationary position. Autotune Notes Before you begin the Autotune procedure, adjust the throttle so that the boat travels at a constant RPM below planing speed, with enough speed to maintain responsive steering. Select Begin when you are ready. The boat will perform a number of zigzag motions while the Autotuning is in progress. When the GHC 10 displays a completion message, select Done. Be sure to take manual control of the boat when Autotuning is complete. If the Autotuning fails: • Increase the throttle approximately 200 RPM and select Retry to begin the process again. • If it fails again, continue retrying the process adding increments of 200 RPM. • If you reach planing speed through adding increments of 200 RPM and the autotune procedure continues to fail, reduce speed below planing speed and select Alternate Autotune to begin an alternate autotuning procedure. CAuTiON: The Alternate Autotune is only applicable to a small number of boats, and should be the last attempt at autotuning. Do not perform the Alternate Autotune until you are sure the standard autotune procedure will not work on your boat. NOTE: If the autotune procedure continually fails, it is possible that air is present in the hydraulic system. It is also possible that a leak or other problem exists in the hydraulic system. If you cannot complete the autotune procedure or the Alternate Autotune, check the hydraulic system on your boat for leaks or other problems, and bleed it completely if necessary. September 2008 190-00894-06 Rev. A Printed in Taiwan Evaluating the Results of the Autopilot Configuration When the Dockside and Sea Trial Wizards are complete, test the autopilot to be sure it is configured correctly. Test the autopilot first at slow speeds (below planing), and then test the autopilot at planing speeds. To test 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. When you release the turn button, the boat should overshoot the turn and quickly correct the heading to the point at which you released the button. You will notice that the faster you are going, the greater the boat will overshoot the turn. 3. If the autopilot is configured properly at slow speeds, repeat these tests at planing speed, and vice versa. To adjust the autopilot configuration if necessary: 1. If you feel that the heading hold oscillates significantly or that the autopilot does not quickly correct the heading when turning, you can make slight adjustments to the rudder gain. NOTE: When you manually adjust the rudder gain (or counter gain), make small adjustments, and adjust only one value at a time. Test the change before entering any further adjustments. 2. On the GHC 10, select Menu > Setup > Dealer Autopilot Configuration > Turn Fine Tuning Setup > Rudder Gains to access the rudder gain adjustments. There are two types of gain settings at both low and high speeds: • Rudder Gain—Adjusts how tightly the rudder holds the heading and makes turns. 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 t...
