Garmin GHP Compact Reactor Hydraulic Autopilot Starter Pack Configuration Guid - Page 3

1 Select an option: • If you are performing this procedure as part of the Sea Trial Wizard, proceed to step 3. • If you are performing this calibration outside of the Sea Trial Wizard on a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Compass Setup > Fine Heading Adjustment. • If you are performing this calibration outside of the Sea Trial Wizard on a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Compass Setup > Fine Heading Adjustment > Begin. 2 Adjust the fine heading setting until it shows the correct heading as determined by a trusted heading indicator, such as the ship compass or a handheld compass. 3 Select Back. Testing and Adjusting the Configuration NOTICE Test the autopilot at a slow speed. After the autopilot has been tested and adjusted at a slow speed, test it at a higher speed to simulate normal operating conditions. 1 Drive the boat in one direction with the autopilot engaged (heading hold). The boat may oscillate slightly, but it should not oscillate significantly. 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 (Adjusting the Acceleration Limiter Settings, page 3). • If the heading hold oscillates significantly or the boat does not correct when turning, adjust the autopilot gain (Adjusting the Autopilot Gain Settings, page 3). • If the boat turns smoothly, the heading hold oscillates only slightly or not at all, the boat adjusts the heading correctly, the configuration is correct. No further adjustments are necessary. Adjusting the Acceleration Limiter Settings 1 On a helm control, enable Dealer Mode (Enabling Dealer Configuration on the Helm Control, page 3). 2 Select an option: • On a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Autopilot Tuning > Acceleration Limiter. • On a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Autopilot Tuning > Accel. Limiter. 3 Select an option: • Increase the setting if the autopilot turns too quickly. • Decrease the setting if the autopilot turns too slowly. When you manually adjust the acceleration limiter, make relatively small adjustments. Test the change before making additional adjustments. 4 Test the autopilot configuration. 5 Repeat steps 2 through 4 until the autopilot performance is satisfactory. Adjusting the Autopilot Gain Settings The autopilot gain settings are set during the Autotune procedure. Adjusting these values is not recommended, and you should record the values set by the Autotune procedure before making any changes. 1 On a helm control, enable Dealer Mode (Enabling Dealer Configuration on the Helm Control, page 3). 2 Select an option: • On a helm control, from the heading screen, select Menu > Setup > Dealer Autopilot Setup > Autopilot Tuning > Rudder Gains. • On a chartplotter, select Settings > My Vessel > Autopilot Installation Setup > Autopilot Tuning > Rudder Gains. 3 Select an option based on the type of boat: • If you have a sailboat, a displacement-hull powerboat, or a powerboat with the speed source set to None, select Gain and adjust how tightly the rudder holds the heading and makes turns. If you set this value too high, the autopilot may be overactive and attempt to constantly adjust the heading at the slightest deviation. An overactive autopilot can drain the battery at a faster-than-normal rate. • If you have a sailboat, a displacement-hull powerboat, or a powerboat with the speed source set to None, select Counter Gain and adjust how tightly the rudder corrects the turn overshoot. If you set this value too low, the autopilot can overshoot the turn again when it attempts to counter the original turn. • If you have a planing-hull powerboat with the speed source set to Tach. - NMEA 2000 or Proprietary, Tachometer, or GPS, select Low Speed or High Speed and 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 and attempt to constantly adjust the heading at the slightest deviation. An overactive autopilot can drain the battery at a faster-than-normal rate. • If you have a planing-hull powerboat with the speed source set to Tach. - NMEA 2000 or Proprietary, Tachometer, or GPS, select Low Speed Counter or High Speed Counter to adjust how tightly the rudder corrects the turn overshoot. If you set this value too low, the autopilot can overshoot the turn again when it attempts to counter the original turn. 4 Test the autopilot configuration, and repeat step 2 and 3 until the autopilot performance is satisfactory. Advanced Configuration Settings You can run the autotune process, calibrate the compass, and define north on the autopilot without running the wizards. You can also define each setting individually, without running the configuration processes. Enabling Dealer Configuration on the Helm Control Advanced configuration options are not available on the helm control under normal conditions. To use the advanced configuration settings of the autopilot, you must enable Dealer Mode. Enabling Dealer Mode to use the configuration options is not necessary on a chartplotter. 1 On a helm control, from the heading screen, select Menu > Setup > System > System Information. 2 Hold the center key for 5 seconds. Dealer Mode appears. 3 Select Back > Back. Configuring the Autopilot 3
