aidAlthough we have designed this product to be accurate and reliable many factors can affect its performance As a result it should only be used as an aid to navigation and should never replace common sense and navigational judgement Always maintain a permanent watch so you can respond to situations as they develop Your Raymarine autopilot will add a new dimension to your boating enjoyment However it is the skippers responsibility to ensure the safety of the boat at all times by following these basic rulesEnsure that someone is present at the helm AT ALL TIMES to take manual control in an emergencyMake sure that all crew members know how to disengage the autopilot you cannot handsteer with the wheel pilot check for other boats and any obstacles to navigation no matter how clear the sea may appear a dangerous situation can develop an accurate record of the boats position by using either a navigation aid or visual a continuous plot of your boats position on a current chart Ensure that the locked autopilot heading will steer the boat clear of all obstacles Make proper allowance for tidal set the autopilot cannotEven when your autopilot is locked onto the desired track using a navigation aid always maintain a log and make regular positional plots Navigation signals can produce significant errors under some circumstances and the autopilot will not be able to detect these

while the display is flashing the autopilot will maintain the current headingOff course alarmThe off course alarm sounds if the locked autopilot heading and the boats current heading differ by more than the value set in 6 see page64econds Cancelling the off course alarmTo cancel the off course alarm press STANDBY to return to manual steeringThe off course alarm is usually an indication that the boat is carrying too much sail or that the sails are badly balanced In these conditions you can usually significantly improve course keeping by improving the sail Page 13 Wednesday July 25 2001 1210 PM14ST3000 Wheel Drive Autopilot Owners HandbookUsing the Wheel PilotAutomatic deadband control Auto SeastateThe wheel pilot is set to AutoSeastate automatic deadband control as a default This causes the pilot to gradually ignore repetitive movements of the boat and respond only to true course variations By preventing unnecessary rudder movement AutoSeastate provides the best compromise between power consumption and course keeping accuracyIf you want to switch off the AutoSeastate feature1With the pilot in Auto mode press 1 together to switch from AutoSeastate to Fixed Minimum Deadband 12The sign flashes when Fixed Minimum Deadband is selected Minimum deadband provides the tightest course keeping possible at the expense of increased power consumption and drive unit activity To switch back to AutoSeastate press 1 The autopilot reverts to Automatic Deadband Control each time you select Standby modeOperating hints trim make major course changes when steering MANUALLY This ensures that the boat will safely clear any obstructions or other boats and you can take into account the changed wind and sea conditions on the new heading before engaging the autopilotLarge course changes which change the apparent wind direction can produce large trim changes When a sudden trim change occurs for example due to weather helm or sail imbalancehere will be a delay of up to one minute before the automatic trim applies rudder to restore the locked heading 811941book Page 14 Wednesday July 25 2001 1210 PMChapter 2 Using the Wheel Pilot15Using the Wheel PilotIn these situations the autopilot will not immediately assume the new automatic heading and will only settle onto course when the automatic trim has been fully established To minimize this problem use the following procedure to make major course changes1Note the required new heading2Press STANDBY disengage the clutch and steer manually3Bring boat onto the new heading and engage the clutch4Press AUTO and let the boat settle on course5Bring your boat onto the final course in 1 steps using Gusting conditionsIn gusting conditions the course may tend to wander slightly particularly if the sails are badly balanced By improving sail balance you can improve course keeping If you take the following precautions the autopilot will be able to maintain competent control even in gale force conditions Do not allow the boat to heel over the mainsheet traveller to leeward to reduce heeling and weather helmIf necessary reef the mainsail a little earlyIt is also advisable whenever possible to avoid sailing with the wind dead astern when there are very strong winds and large seasIdeally the wind should be at least 30 away from a dead runIn severe conditions it may be advisable to remove the mainsail altogether and sail under headsail only 811941book Page 15 Wednesday July 25 2001 1210 PM16ST3000 Wheel Drive Autopilot Owners HandbookUsing the Wheel display illumination on and offYou can switch the display illumination on and off when the wheel pilot is in Standby modefrom Standby mode press and 1 together to switch the illumination between on d off to return to the previous mode either wait 10 seconds or press the appropriate mode key The wheel pilot normally powersup with the illumination switched on If other SeaTalk instruments or autopilot control units are connected via SeaTalk you can also control the wheel pilots illumination from these Page 16 Wednesday July 25 2001 1210 PMChapter 2 Using the Wheel Pilot17Using the Wheel Pilot24Using Track modeIn Track mode the wheel pilot maintains a track between waypoints created on a navigation system The wheel pilot computes any course changes to keep your boat on track automatically compensating for tidal streams and leeway To operate in Track mode the wheel pilot must receive cross track error information from eithera SeaTalk navigator ora nonSeaTalk navigation system transmitting NMEA 0180 or 0183 dataNote using NMEA 0180 navigatorsNMEA 0180 equipment only transmits cross track error up to 03 nm This means that even if you are 5 nm to starboard of track the transmitted data will still be 03 nm If you attempt to engage Trackmode with the boat more than 03 nm from track the boat will overshoot excessively and may even circle For this reason the Larger Cross Track Error alarm seepage24s displayed whenever cross track error is 03 nm or greater The requirement to remain within 03 nm of track also limits the maximum allowable angular error between the track course and the boats heading If the angular error is too great the autopilot will be unable to cancel it within the 03 nm limit leading to the problems outlined aboveNMEA 0183 transmit cross track error up to 9999 nm and so enables Track mode to operate with larger cross track errors However the autopilot will still display the alarm if cross track error exceeds 03nm in case there are any hazards close to the intended track Selecting Track modeWhen you select Track mode the wheel pilot can acquire the track in one of two waysautomatic acquisition when both cross track error and bearing to waypoint data are acquisition when Cross Track Error is the only available Page 17 Wednesday July 25 2001 1210 PM18ST3000 Wheel Drive Autopilot Owners HandbookUsing the Wheel PilotAutomatic track acquisitionIf cross track error and bearing to waypoint data are both available via SeaTalk or NMEA the pilot can acquire a track automatically 1Bring the boat to within 01 nm of track 2Press AUTO3Press 10 and 10 together to enter Track mode4An alarm will sound and the display will alternate betweenthe bearing to waypoint and the direction the boat will turn to take up the new track 5Check that it is safe to turn the boat onto the new course6Press 10 and 10 togetherthe boat will

to within 01 nm of track2Bring the heading to within 5 of the bearing to the next waypoint 3Press AUTO4Press 10 and 10 together to enter Track mode the autopilot will start tracking to the waypointthe display will alternate between cross track error and the locked pilot headingManual track acquisition at low speedsUsing manual acquisition at low speeds requires additional care as tidal streams have a far more significant effect at lower speeds than at higher speeds In general terms if the tidal flow is less than 35 of the boats speed you will not notice any difference in the wheel pilots performance in Track mode However you should take extra care during manual acquisition as follows before you select Track mode make sure that the boat is as close as possible to track and that the direction made good over the ground is as close as possible to the direction of the next waypoint positive checks of the boats position at regular intervals are vital especially if you are close to

22 Wednesday July 25 2001 1210 PMChapter 2 Using the Wheel Pilot23Using the Wheel PilotSafety in Track mode provides accurate track keeping even in complex navigational situations However it is still the skippers responsibility to ensure the safety of their boat at all times through careful navigation and frequent position checks Passage making in Track mode assists precise navigation and removes the tasks of compensating for wind and tidal drift However you MUST still maintain an accurate log with regular position at the start of a journeyAt the start of a journey you must always use an easily identifiable fixed object to confirm the fix given by the navigation system Check for fixed positional errors and compensate for themVerifying computed verify the computed position with a dead reckoned position calculated from the average course steered and the distance loggedPlot frequencyIn open water you should make plots at least every hour In confined waters or when near to potential hazards you should make plots more waypointsLocal variations in radio signal quality and changes in the tidal stream can produce deviations from the desired track When setting waypoints remember that deviations can check along each track Check up to 05nm each side of the track to ensure that there are no hazards within this zoneFor the waypoint advance function to work the last four characters of adjacent waypoint names must be different 811941book Page 23 Wednesday July 25 2001 1210 PM24ST3000 Wheel Drive Autopilot Owners HandbookUsing the Wheel PilotWarning messages in Track mode Waypoint

the Wheel Pilot25Using the Wheel Pilot25Using Wind Vane modeYou can only use Wind Vane mode if the wheel pilot is connected to a suitable wind providing wind direction data To use Wind Vane mode the wheel pilot must receive wind information from one of the following sourcesSeaTalk wind instrumentNMEA wind pushpit wind vane part number Z159onnected via the supplied SeaTalk interfaceIn Wind Vane mode the wheel pilot maintains a course relative to an apparent wind angle The pilot uses WindTrim to eliminate the effects of turbulence and short term wind variations This provides smooth precise performance with minimum power consumption Wind Vane mode uses the fluxgate compass as the primary heading reference When changes in the apparent wind angle occur the wheel pilot adjusts the locked compass heading to maintain the original apparent wind angle In Wind Vane mode the wheel pilot ignores shortterm changes in wind direction yet still tracks real wind shifts as subtle as 1Selecting Wind Vane modeFrom Standby mode or Auto mode press STANDBY AUTOtogether to select Wind Vane mode The wheel pilot will then maintain the current apparent wind angle The autopilot beeps once every 30

provides optimum response for offshore conditions where genuine shifts in wind direction occur gradually In gusting and unsteady inshore conditions it is best to sail a few degrees further off the wind so that changes in apparent wind direction can be toleratedIt is important to minimize the amount of standing helm through careful sail trimming and positioning of the mainsheet travellerIt is recommended that the headsail and mainsail are reefed a little early rather than too late811941book Page 27 Wednesday July 25 2001 1210 PM28ST3000 Wheel Drive Autopilot Owners HandbookUsing the Wheel

guidelinesAll Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine design and manufacture conforms to the appropriate Compatibility EMCtandards but correct installation is required to ensure that performance is not compromised Although every effort has been taken to ensure that they will perform under all conditions it is important to understand what factors could affect the operation of the productThe guidelines given here describe the conditions for optimum EMC performance but it is recognized that it may not be possible to meet all of these conditions in all situations To ensure the best possible conditions for EMC performance within the constraints imposed by any location always ensure the maximum separation possible between different items of electrical equipmentFor optimum EMC performance we recommend thatRaymarine equipment and cables connected to it areAt least 3 ft 1 m from any equipment transmitting or cables carrying radio signals eg VHF radios cables and antennas In the case of SSB radios increase the distance to 7ft 2mMore than 7 ft 2 mrom the path of a radar beam A radar beam can normally be assumed to spread 20 degrees above and below the radiating Page 35 Wednesday July 25 2001 1210 PM36ST3000 Wheel Drive Autopilot Owners the Wheel PilotThe equipment is supplied from a separate battery from that used for engine start Voltage drops below 10V and starter motor transients can cause the equipment to reset This will not damage the equipment but may cause the loss of some information and may change the operating modeRaymarine specified cables are used Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manualIf a suppression ferrite is attached to a cable this ferrite should not be removed If the ferrite needs to be removed during installation it must be reassembled in the same positionEMC suppression ferritesWe supply the fluxgate compass and power cables with suppression ferrites fitted Always use these ferrites supplied by Raymarine Connections to other equipmentIf your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine a suppression ferrite MUST always be attached to the cable near to the Raymarine unit811941book Page

trial may result in impaired autopilot performance on some compass headings When you have checked that the system is operating correctly you must complete a short sea trial to calibrate the compass The wheel pilot has a builtin calibration capability so you can finetune it to suit your boat its steering system and its dynamic steering supplied from the factory the autopilot is calibrated to provide safe stable control for most boatsDo not attempt to make any permanent changes to the recommended calibration values until you have completed the sea trialYou must carry out the initial sea trialin conditions of light wind and calm water so you can assess the autopilots performance without the influence of strong winds or large wavesNote At any time during the sea trial you can disengage the clutch lever to return to handsteering Before starting the sea trial Before carrying out the sea trial you shouldcheck the calibration settings and if necessary reset them to the default values see page63check the installation to make sure that it is not affected by radio transmissions engine starting etc Calibrating the compass deviation correctionBy completing the following compass correction procedure the wheel pilot can correct its own internal fluxgate compass for most deviating magnetic fields You MUST complete the Compass Deviation Correction at the beginning of your sea Page 56 Wednesday July 25 2001 1210 PMChapter 5 Commissioning the Wheel the Wheel PilotTo complete the compass and hold STANDBY for 1 second a series of dashes will cycle around the display If you see a CAL OFF message instead of the dashes calibration access has been prevented Refer to page66 for details 2Keeping boat speed below 2 knots turn the boat in slow circles You should take at least 3 minutes to complete each 360 3Keep turning your boat until the display changes to show the amount of deviation the autopilot has detected The deviation alternates with the autopilots current heading every second If the deviation exceeds 15 you should resite the control unit to a location less affected by magnetic interference 811941book Page 57 Wednesday July 25 2001 1210 PM58ST3000 Wheel Drive

the Wheel the Wheel autopilot performanceThe factory setting for rudder gain provides stable control for initial sea trials However different boats can vary widely in their response to the helm and further adjustment to the rudder gain may improve the autopilots steering following test will determine whether the rudder gain is set too high or too low1In clear water and with the autopilot in Auto mode alter course to starboard by 40 by pressing 10 four timesAt cruising speeds a course change of 40 should result in a crisp turn followed by an overshoot of no more than 5If this occurs the rudder gain is set correctlyIf rudder gain is too high the 40 course change will result in a distinct overshoot of more than 5Correct this oversteer by reducing the rudder gain settingIf rudder gain is too low the boats steering performance will be sluggish it will take a long time to make the 40 turn and there will be no overshoot Correct this understeer by increasing the rudder gain setting It is easier to recognize these actions in calm sea conditions where wave action does not mask basic steering 811941book Page 59 Wednesday July 25 2001 1210 PM60ST3000 Wheel Drive Autopilot Owners the Wheel Pilot2Refer to the calibration menu diagram in Chapter 6 Adjusting Wheel Pilot Settings for instructions on how to adjust the rudder gain setting3Repeat the test until you achieve crisp course changes with no more than 5 of overshootYou should set the rudder gain to the lowest setting consistent with accurate course keeping This will minimize drive movements and reduce power consumption and wear and tear811941book Page 60 Wednesday July 25 2001 1210 PMChapter 6 Adjusting Wheel Pilot Wheel Pilot 6Adjusting Wheel Pilot wheel pilot is calibrated at the factory to provide stable performance for

that the autopilot tends to be a little less stable on Northerly headings in the higher latitudes of the Northern hemisphere or Southerly headings in the Southern hemisphereThis is caused by the increasing angle of dip of the earths magnetic field at higher latitudes which has the effect of amplifying rudder response on Northerly Southerly headings This error affects all magnetic compasses and gets worse further away from the equatorWith heading error correction switched on the wheel pilot can compensate for this error by automatically adjusting the autopilot gain depending on heading This will provide precise course keeping on all headings 811941book Page 65 Wednesday July 25 2001 1210 PM66ST3000 Wheel Drive Autopilot Owners Wheel Pilot Level 11 Boats current latitudeWhen you have
