16 GHP 10 Installation InstructionsCalibrating the Compass1. Drive your boat at cruising speed in a straight line.2. Select Begin, and continue to drive in a straight line.3. When instructed, turn the boat slowly clockwise, taking care tomake the turn as steady and flat as possible.Turn slowly so that the boat DOES NOT list.After you successfully complete the calibration, the GHC 10displays a completion message.4. Select an option:• If the calibration completes successfully, select Done.• If the calibration fails, select Retry and repeat steps 1–3.Performing the autotune ProcedureBefore you can perform the autotune procedure, you must have a largestretch of open water available.1. If you have a non-planing vessel, adjust the throttle so the boattravels at a typical cruising speed that provides responsive steering.If you have a planing vessel, adjust the throttle so the boat travelsbelow planing speed.2. Select Begin.The boat performs a number of zigzag motions while the Autotuningis in progress.The GHC 10 displays a completion message.3. Select an option:• If the autotune completed successfully, select Done and takemanual control of the boat.• If the autotune failed, adjust the throttle and select RetryAutotune.• If the autotune failed, and the rudder went hard over or the boatwent in a circle, select Reverse Steering Dir. and Retry.• If you receive an Error: ECU Drive Circuit Overload. Seemanual for tips on reducing load error message, see the tips onpage 17.4. If autotune fails again, repeat steps 1–3 until the autotune completessuccessfully.5. If the autotune procedure continues to fail after you reach maximumcruising speed, reduce your speed to the initial autotune speedand select Alternate Autotune to begin an alternate autotuningprocedure.Setting northBefore you can set north, you must have at least 45 seconds of hazard-free, open water available.This procedure appears if you connect an optional GPS device to theGHP 10 (page 14), and the device has acquired a GPS position. If youdo not have a GPS device connected, you are prompted to set the fineheading adjustment (page 16).1. Drive the boat in a straight line at cruising speed, and select Begin.The GHC 10 displays a completion message when the calibration iscompete.2. Select an option:• If the calibration completed successfully, select Done.• If the calibration failed, repeat steps 1–2.Setting the Fine Heading adjustmentThis procedure appears only if you do not have an optional GPS deviceconnected to the GHP 10 (page 14). If you do have a GPS deviceinstalled on your boat that has acquired a GPS position, are prompted toset north instead (page 16).1. Using a handheld compass, identify north.2. Adjust the fine heading setting until it matches north on themagnetic compass.3. Select Done.Evaluating the Results of the autopilotConfiguration1. Test the autopilot at a slow speed.2. If necessary, adjust the gain setting (page 17).3. If you receive an Error: ECU Drive Circuit Overload. See manualfor tips on reducing load error message, see the tips on page 17.4. Test the autopilot at a higher speed (normal operating conditions).5. If necessary, adjust the gain and acceleration limiter settings.testing and adjusting the autopilot Configuration1. Drive the boat in one direction with the autopilot engaged (headinghold).The boat should not oscillate significantly; however, a small amountof oscillation is normal.2. Turn the boat in one direction using the autopilot and observe thebehavior.The boat should turn smoothly, not too quickly or too slowly.When you turn the boat using the autopilot, the boat shouldapproach and settle on the desired heading with minimal overshootand oscillation.3. Select an option:• If the boat turns too quickly or too sluggishly, adjust theautopilot acceleration limiter (page 16).• If the heading hold oscillates significantly or the boat does notcorrect when turning, adjust the autopilot gain (page 17).• If you receive an Error: ECU Drive Circuit Overload. Seemanual for tips on reducing load error message, see the tips onpage 17.• If the boat turns smoothly, the heading hold oscillates onlyslightly 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 holdoscillates only slightly or not at all, and the boat adjusts the headingcorrectly.5. For planing vessels, repeat steps 1–4 at faster speeds (page 16).adjusting the acceleration Limiter SettingsNOTE: When you manually adjust the acceleration limiter, makerelatively small adjustments. Test the change before making additionaladjustments.1. Enable the advanced configuration procedure (page 17).2. On the GHC 10, select Menu > Setup > Dealer AutopilotConfiguration > 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 10 performance is satisfactory.
