    Initiate the Tack or Gybe function by selecting the Tack/Gybe • option in the Mode list. - The turn is started when the direction is selected in the dialog. NoDrift mode Ú Note: It is not possible to select NoDrift mode if GPS position and heading information is missing.

  • Page 19: Heading Capture

    Heading capture When the vessel is turning in AUTO mode, an instant re-press on the AUTO key or the rotary knob activates the heading capture function. This will automatically cancel the turn, and the vessel will continue on the heading read from the compass the very moment you pressed the AUTO key or the rotary knob.
  • Page 20 Prior to entering NAV mode the navigator must be navigating a route or towards a waypoint. • Initiate NAV mode by selecting the NAV option in the Mode list • Confirm to switch to NAV mode in the dialog. Turning in NAV mode When your vessel reaches a waypoint, the autopilot will give an audible warning and display a dialog with the new course information.

  • Page 21: Turn Pattern Steering

    The limit for automatic course change is set during commisioning of the autopilot computer. For more information refer to "Autopilot settings" on page 36. Turn pattern steering The system includes a number of automatic turn steering features when the autopilot is in AUTO mode. Ú...
  • Page 22 • Turn variable: - Rate of turn. Increasing the value makes the vessel turn a smaller circle. U-turn Changes the current set heading to be 180° in the opposite direction. The turn rate is set during commisioning of the autopilot computer. For more information refer to "Autopilot settings"...
  • Page 23 • Turn variables: - Course change (C) - Turn radius (D) Depth contour tracking (DCT) Makes the autopilot follow a depth contour. Ú Note: DCT turn pattern is only available if the system has a valid depth input. Warning: Do not use the DCT turn pattern unless the seabed is suitable.

  • Page 24: Using The Autopilot In An Evc System

    Port option Starboard option (depth decreases to port) (depth decreases to starboard) • Turn variables: - Depth gain. This parameter determines the ratio between commanded rudder and the deviation from the selected depth contour. The higher depth gain value the more rudder is applied.

  • Page 25: Steadysteer

    When the autopilot is connected to an EVC system, you can take manual control of the steering regardless of the autopilot mode. The mode indicator is replaced by a dash to indicate EVC override. The autopilot goes into standby mode if no rudder command is given from the EVC system within a predefined period.

  • Page 26: Trip Log

    Trip log The Trip log is available from the Settings menu. There are three log options available: • Trip 1: records distance traveled through the water (Log input) • Trip 2: records distance traveled via GPS input • Log: shows total distance run from system installation or from a system restore Ú...

  • Page 27: Alarms

    Alarms The system continuously checks for dangerous situations and system faults while the system is running. The alarm system can be activated if any alarm settings are exceeded. Ú Note: If sensor data vital for autopilot operation (e.g. rudder response) is lost when the autopilot is running in an automatic mode, the system will automatically switch to Standby mode.

  • Page 32 Wind MHU (Masthead unit) alignment This provides an off set calibration in degrees to compensate for any mechanical misalignment between the masthead unit and the center line of the vessel. To check the masthead unit alignment error we recommend you use the following method which involves a sailing trial: •...
  • Page 33 +0.5 -2.0 +0.0 Aft depth offset This option allows the system to display two depth readings. The Aft depth is calibrated in the same manner as the Depth offset. Ú Note: Aft Depth is only available when a valid signal is received from a second and compatible NMEA 2000 or NMEA 0183 device.
  • Page 34 User triggered calibration Ú Note: Before the calibration is started, make sure that there is enough open water around the vessel to make a full turn. The Calibrate option is used for manually starting the heading calibration procedure. During this calibration, the compass measures the magnitude and direction of the local magnetic field.

  • Page 35: Damping

    Advanced This option is used for manually applying an offset to the displayed data for third party sensors which cannot be calibrated through the AP48. Damping If data appears erratic or too sensitive, damping may be applied to make the information appear more stable. With damping set to off, the data is presented in raw form with no damping applied.

  • Page 36: Autopilot Settings

    Autopilot settings The autopilot settings can be split between settings done by the user, and settings done during installation and commissioning of the autopilot system. • User settings can be changed for various operational conditions or user preferences • Installation settings are defined during commissioning of the autopilot system.
