Autopilot is not The autopilot is no longer receiving navigation receiving valid navigation data. Autopilot placed data while performing a in Heading Hold. Route To maneuver. This message also appears if navigation is stopped on a chartplotter before the autopilot is disengaged. Connection with Autopilot Lost The helm control has lost connection with the CCU. Lost Wind Data (sailboat only) The autopilot is no longer receiving valid wind data. Autopilot Action • Alarm sounds for 5 seconds • Continues in normal operation • Alarm sounds for 5 seconds • Autopilot transitions to heading hold N/A • Alarm sounds for 5 seconds • Autopilot transitions to heading hold 12 Error Message Low GHC™ Supply Voltage Error: ECU High Voltage Error: ECU Voltage has Dropped Rapidly Error: ECU High Temperature Error: Lost Communication Between ECU and CCU (when the autopilot is engaged) Cause The supply voltage level has fallen below the value specified in the low voltage alarm menu. The pump supply voltage has risen above 33.5 Vdc. The ECU voltage has dropped quickly below 7.0 Vdc. The ECU temperature has risen above 100°C (212°F ). Communication between the CCU and the pump has timed out. Autopilot Action N/A • Alarm sounds for 5 seconds • The ECU shuts down • Alarm sounds for 5 seconds • The error is cleared when the ECU voltage rises above 7.3 Vdc. • Alarm sounds for 5 seconds • The ECU shuts down • The helm control beeps, and autopilot transitions to standby. Detailed Configuration Settings Although all of the configuration is typically completed automatically through wizards, you can manually adjust any setting to fine-tune the autopilot. Advanced configuration settings are available only when using Dealer Mode (Enabling Dealer Configuration). User-specific settings are available during normal operation of the autopilot. See the configuration section of the owner's manual provided with the autopilot for more information. NOTE: Depending upon the configuration of the autopilot, certain settings may not appear. NOTE: On a powerboat, each time you change to the Speed Source setting, you must review the Verify Tachometer, Low RPM Limit, High RPM Limit, Planing RPM, Planing Speed, or Max. Speed settings, where applicable, before performing the autotune procedure (Performing the Autotune Procedure). Autopilot Tuning Settings To open the general autopilot tuning settings, select Menu > Setup > Dealer Autopilot Setup. Acceleration Limiter: Allows you to limit the speed of autopilot- controlled turns. You can increase the percentage to limit the turn rate, and decrease the percentage to allow higher turn rates. Speed Source Settings NOTE: Speed source settings are available only for power boats. To open the speed source settings, select Menu > Setup > Dealer Autopilot Setup > Speed Source Setup. Speed Source: Allows you to select the speed source. Verify Tachometer: Allows you to compare the RPM readings on the helm control with the tachometers on the dashboard of your boat. Planing RPM: Allows you to adjust the RPM reading on the helm control at the point when your boat transitions from displacement to planing speed. If the value does not match the value on the helm control, you can adjust the value. Planing Speed: Allows you to adjust the planing speed of your boat. If the value does not match the value on the helm control, you can adjust the value. Low RPM Limit: Allows you to adjust the lowest RPM point of your boat. If the value does not match the value on the helm control, you can adjust the value.
