Aligning compass manuallyWhere no GPS is present manual alignment of the compassis required.1. Continue to steer on a steady course and use the Use +1 and-1 buttons, or the ROTARY controller to adjust the headingdisplayed until it matches the vessel’s compass reading.2. When complete press CONTINUE to begin Autolearn.Auto LearnYou must have significant clear water in front of the vessel toaccommodate a series of maneuvers, which include sudden,sharp turns. There should be a clear area at least 100m wideand 500m ahead.D12106-1Caution: AutolearnPlease ensure sufficient free space ahead.(Minimum 100x500m long & significantly more for ahigh speed vessel.Performing Auto learnAuto learn is available from the Sea trial wizard, or from theCommissioning menu.Maintain a normal cruising speed (at least 3 kts) throughout theauto learn process.1. Ensure there is sufficient free water in front of the vessel andselect continue.A warning message is displayed.2. Select Continue or press the Ok button.A warning message will be displayed letting you know thatthe vessel will zigzag and make Sudden SHARP TURNS.3. Remove your hands from the wheel and press Auto to begin.During this procedure the autopilot will progress through therequired steps.4. If ‘PASS’ is displayed then select Continue or press the Okbutton to return to manual helm control.The autopilot will by placed in Standby mode. You havesuccessfully completed the commissioning process for yourSmartPilot system.5. If ‘FAIL’ is displayed after completion of the Auto learnprocess then select Continue or press the Ok button.The Auto learn retry message is displayed.6. You can retry the Auto learn process by selecting Yes or tocancel select No.Note: The Sea trial wizard can be cancelled at any time bypressing the Standby button.Caution: System changesAny additional changes you make to your systemsettings may require you to repeat the calibrationprocess.8.10 Checking autopilot operationAfter completing calibration, check the basic autopilot operation,as follows:1. Steer onto a compass heading and hold a steady courseat normal cruising speed. If necessary, steer the vesselmanually for a short time to check how the vessel steers.2. Ensure it is safe to engage the autopilot, then press AUTO tolock onto the current heading. The autopilot should hold aconstant heading in calm sea conditions.3. Use -1, +1, -10 and +10 or the ROTARY controller, to seehow the SmartPilot alters the course to port and starboard.4. Press STANDBY to return to manual steering.Checking rudder gainTo determine whether the rudder gain is set correctly, carry outthe following test:D12107-1123Item Description1. Rudder gain too low2. Rudder gain too High3. Correct rudder gain1. Ensure you have set the autopilot response to level 5.2. Drive your vessel at a typical cruising speed in clear water.It is easier to recognize the steering response in calmsea conditions where wave action does not mask steeringperformance.3. Press AUTO to enter Auto mode, then alter course by 40°:• This course change should result in a crisp turn followedby an overshoot of no more than 5°, If the rudder gain isadjusted correctly.• If the course change causes a distinct overshoot (morethan 5°) and/or there is a distinct ‘S’ in the course therudder gain is too high.• If the vessel’s performance is sluggish and it takes a longtime to make the 40° turn, with no overshoot the ruddergain is too low.If necessary, adjust the rudder gain.Checking counter rudderCounter rudder is the amount of rudder your autopilot appliesto try to prevent your vessel from veering off course. Highercounter rudder settings result in more rudder being applied.To check the counter rudder setting:1. Ensure you have set the autopilot response to level 5.2. Drive your vessel at a typical cruising speed in clear water.3. Press AUTO to switch the autopilot to Auto mode, then makea 90° course change:• When rudder gain and counter rudder are both setcorrectly, the vessel performs a smooth continuous turnwith minimal overshoot.• If the counter rudder is too low, the vessel will stillovershoot.• If counter rudder is too high, the vessel will ‘fight’ the turnand make a series of short, sharp turns. This results in avery ‘mechanical’ feel as the vessel changes course.Commissioning - SPX and SmartPilot systems 51
