Chapter 1: Introduction
1.1 Overview




                                                                                              1 Introduction
                                                                                D5652-1


                  The ST3000 wheel pilot is a cockpit autopilot for wheel steered boats.
                  It is designed for owner installation and consists of two main units:
                     bracket mounted ST3000 control unit with built-in compass
                     proven ST3000 wheel drive unit
                  ST3000 control unit
                  Operating modes
                  The wheel pilot has four basic operating modes:
                     Standby mode: autopilot off
                     Auto mode: autopilot engaged and locked onto a heading
                     Track mode: autopilot on and maintaining a track between two
                      waypoints created on a navigation system
                     Wind Vane mode: autopilot on and maintaining a course relative
                      to an apparent wind angle
                  SeaTalk and NMEA compatibility
                  The ST3000 control unit is SeaTalk compatible, so it can share data
                  transmitted from other Raymarine SeaTalk instruments:
                     wind information from a wind instrument can be used for
                      wind vane steering without the need to install a separate vane
                 2                     ST3000 Wheel Drive Autopilot - Owner's Handbook

                        track information, from a navigator, can provides waypoint
                         control from the autopilot
                        boat speed from a speed instrument can provide optimum track
1 Introduction




                         keeping performance
                        SeaTalk compatibility also allows additional fixed and hand-held
                         autopilot control units to be easily connected at secondary
                         steering and control positions
                     With an optional SeaTalk/NMEA interface (part number: E85001)
                     the wheel pilot can also be used with any navigator or position sensor
                     transmitting NMEA 0183.
                     The ST3000 can be calibrated to suit each installation. This can
                     provide optimum performance with many types of boat and
                     steering systems.
                     ST3000 wheel drive unit
                     The wheel drive unit is attached by a single pin to a clevis
                     permanently fixed to the cockpit structure. Drive is transmitted to the
                     wheel by a tensioned toothed belt. A lever operated eccentric bush in
                     the drive unit mounting arm enables belt tension to be released to
                     facilitate manual override by allowing the belt to slip. The drive
                     disengagement system is both effective and reliable.

                     CAUTION:
                     The ST3000 is recommended for wheel steered boats up to
                     7000 kg (15,000 lb) displacement. Above this limit and for heavy
                     duty applications, such as single handed racing or long distance
                     ocean sailing, we recommend one of the more powerful
                     Raymarine autopilots (such as the ST5000+ system or
                     Type 150/400 course computer).

                  could result in poor product performance, personal injury
                  and/or damage to your boat.
                  WARNING:         Electrical safety
                  Make sure the power supply is switched off before you make any
                  electrical connections.
                  WARNING:         Navigation aid
                  Although 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 skipper's responsibility to ensure the
                  safety of the boat at all times by following these basic rules:
                     Ensure that someone is present at the helm AT ALL TIMES, to
                      take manual control in an emergency.
                     Make sure that all crew members know how to disengage the
                      autopilot  you cannot handsteer with the wheel pilot engaged.
                     Regularly check for other boats and any obstacles to navigation 
                      no matter how clear the sea may appear, a dangerous situation can
                      develop rapidly.
                     Maintain an accurate record of the boat's position by using either
                      a navigation aid or visual bearings.
                     Maintain a continuous plot of your boat's 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 cannot.
                     Even 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 errors.

Chapter 2: Using the Wheel Pilot
2.1 Overview
                  WARNING:
                  Passage making under autopilot control is an enjoyable
                  experience that can, if you are not careful, lead to the relaxation
                  of the permanent watch. Always maintain a permanent watch no
                  matter how clear the sea may appear to be.
                     The wheel pilot always powers up in Standby mode (indicated by
                      a flashing `C' alongside the boat's current compass heading).




                                                                                                 2 Using the Wheel Pilot
                     The wheel pilot is controlled using simple push-button
                      operations. The control unit confirms all button presses with a
                      short beep. In addition to the main single key functions, there are
                      several dual key operations.
                     To select automatic steering:
                       steady the boat on the required heading
                       engage the wheel drive clutch
                       press AUTO: the display will then show an `A' alongside the
                          current heading
                     To return to manual steering at any time:
                       press STANDBY
                       disengage the clutch lever
                     You can use the -1, +1, -10, and +10 keys to make course changes
                      when the boat is under autopilot control.




                                                                                   D5608-1

                                     To return to hand steering:
                                     1. Press standby: the wheel pilot will return to Standby mode.
                                        The display will show a flashing `C' and the boat's current
                                        compass heading.
                                     2. Disengage the wheel drive clutch by rotating the clutch lever
                                        anti-clockwise.
                                     3. The last heading is memorized and can be recalled (see page 13).

                                             2. When safely clear of the obstacle, you can either:
                                                 reverse the previous course change (for example, by pressing
                                                  +10 three times), or
                                                 return to the previous heading (see below)

                  Cancelling the off course alarm
                  To cancel the off course alarm, press STANDBY to return to manual
                  steering.
                  Note: The 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 balance.

                               Automatic deadband control (Auto Seastate)
                                      The 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 accuracy.
                                      If you want to switch off the AutoSeastate feature:
                                      1. With the pilot in Auto mode, press -1 and +1 together to switch
                                         from AutoSeastate to Fixed Minimum Deadband (1).
                                      2. The "" sign flashes when Fixed Minimum Deadband is selected.
2 Using the Wheel Pilot




                                         Minimum deadband provides the tightest course keeping
                                         possible, at the expense of increased power consumption and
                                         drive unit activity.

                                      Note: The autopilot reverts to Automatic Deadband Control each
                                      time you select Standby mode.

                                      CAUTION:
                                      Only 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 autopilot.
                                      Large 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 imbalance) there will be a delay
                                      of up to one minute before the automatic trim applies rudder to restore
                                      the locked heading.

                  In 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 changes:
                  1.   Note the required new heading.
                  2.   Press STANDBY, disengage the clutch, and steer manually.
                  3.   Bring boat onto the new heading and engage the clutch.
                  4.   Press AUTO and let the boat settle on course.
                  5.   Bring your boat onto the final course in 1 steps using -1 or +1.
                  Gusting conditions
                  In gusting conditions, the course may tend to wander slightly,




                                                                                              2 Using the Wheel Pilot
                  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 excessively.
                      Ease the mainsheet traveller to leeward to reduce heeling and
                       weather helm.
                      If necessary, reef the mainsail a little early.
                      It is also advisable (whenever possible) to avoid sailing with the
                       wind dead astern when there are very strong winds and large seas.
                      Ideally, the wind should be at least 30 away from a dead run.
                      In severe conditions, it may be advisable to remove the mainsail
                       altogether and sail under headsail only.

                                     these units.
Chapter 2: Using the Wheel Pilot                                                        17


2.4 Using Track mode
                  In 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 either:
                     a SeaTalk navigator, or
                     a non-SeaTalk navigation system transmitting NMEA 0180 or
                      0183 data

                  Note: using NMEA 0180 navigators




                                                                                             2 Using the Wheel Pilot
                  NMEA 0180 equipment only transmits cross track error up to 0.3
                  nm. This means that even if you are 5 nm to starboard of track, the
                  transmitted data will still be 0.3 nm.
                  If you attempt to engage Track mode with the boat more than 0.3 nm
                  from track, the boat will overshoot excessively and may even circle.
                  For this reason, the Larger Cross Track Error alarm (seepage 24) is
                  displayed whenever cross track error is 0.3 nm or greater.
                  The requirement to remain within 0.3 nm of track also limits the
                  maximum allowable angular error between the track course and the
                  boat's 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 above.
                  NMEA 0183 transmit cross track error up to 99.99 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
                  0.3 nm in case there are any hazards close to the intended track.

       Selecting Track mode
                  When you select Track mode, the wheel pilot can acquire the track in
                  one of two ways:
                     automatic acquisition  when both cross track error and bearing to
                      waypoint data are available
                     manual acquisition  when Cross Track Error is the only available
                      information

                               Automatic track acquisition
                               If cross track error and bearing to waypoint data are both available
                               (via SeaTalk or NMEA), the pilot can acquire a track automatically:
                               1.   Bring the boat to within 0.1 nm of track.
                               2.   Press AUTO.
                               3.   Press -10 and +10 together to enter Track mode.
                               4.   An alarm will sound and the display will alternate between:
                                     the bearing to waypoint, and
                                     the direction the boat will turn to take up the new track

                  Manual track acquisition
                  If your navigator only provides cross track error information, you
                  must acquire the track manually:
                  1.   Steer the boat to within 0.1 nm of track.
                  2.   Bring the heading to within 5 of the bearing to the next waypoint.
                  3.   Press AUTO.
                  4.   Press -10 and +10 together to enter Track mode:
                        the autopilot will start tracking to the waypoint
                        the display will alternate between cross track error and the
                          locked pilot heading

                  Manual track acquisition at low speeds
                  Using 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 boat's speed,
                  you will not notice any difference in the wheel pilot's 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 boat's position at regular intervals are vital,
                       especially if you are close to potential navigational hazards

                               Returning to Auto from Track mode
                                      To return to Auto mode from Track mode:
                                         press AUTO, or

                               Cross track error (XTE)
                                      Cross track error (XTE) is the distance between your current position
                                      and the planned route. This is displayed in nautical miles (nm) and is
                                      taken directly from your navigator.

       Tidal stream compensation
                  Under most operating conditions, Track mode will hold the selected
                  track to within 0.05 nm (300 ft) or better.
                  The autopilot takes account of the boat's speed when computing
                  course changes to ensure optimum performance over a wide range of
                  boat speeds. If speed data is available, the autopilot will use the
                  measured boat speed. Otherwise it will use the default cruise speed
                  entered in Calibration Level 5 (see page 64).

                               Waypoint arrival and advance
                                     IMPORTANT NOTE:
                                     Waypoint advance will only operate if the wheel pilot receives
                                     valid waypoint name and bearing to waypoint information.
                                     If your navigator transmits valid waypoint name and bearing to
                                     waypoint data, you can advance from one waypoint to the next
                                     by pressing -10 and +10 together.
                                     Arrival
                                     As the boat passes the target waypoint, the navigator manually or
                                     automatically selects the next target waypoint. The pilot will then:

                                        detect the new target waypoint name
                                        sound the waypoint advance alarm
                                        display the new bearing to waypoint and the direction the boat

                                     Advance
                                     When the waypoint advance alarm is sounding, the wheel pilot will
                                     suspend Track mode and maintain the current heading:
                                        check that it is safe to turn onto the new track
                                        press the -10 and +10 keys together: this will cancel the waypoint
                                         arrival alarm and turn the boat towards the next waypoint
                                     Unless you accept the waypoint advance in this way, the alarm will
                                     continue to sound and the autopilot will maintain the current course.

                               Dodges in Track mode
                                     In Track mode, you still have full control from the keypad:
                                        to make a dodge maneuver: use the -1, +1, -10 or +10 keys
                                        after you have avoided the hazard, reverse the course change
                                         selected for the dodge maneuver by selecting an equal course
                                         change in the opposite direction
                                        if the boat remains within 0.1 nm of track, there is no need to steer
                                         back towards the track

       Safety in Track mode
                  WARNING:
                  Track mode provides accurate track keeping even in complex
                  navigational situations. However, it is still the skipper's
                  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 plots:

                  Confirming position at the start of a journey




                                                                                             2 Using the Wheel Pilot
                     At 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 them.

                  Verifying computed positions
                     Always verify the computed position with a dead reckoned
                      position, calculated from the average course steered and the
                      distance logged.

                  Plot frequency
                     In open water, you should make plots at least every hour.
                     In confined waters or when near to potential hazards, you should
                      make plots more frequently.

                  Setting waypoints
                     Local 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 occur.
                     Thoroughly check along each track. Check up to 0.5 nm each side
                      of the track to ensure that there are no hazards within this zone.
                     For the waypoint advance function to work, the last four
                      characters of adjacent waypoint names must be different.

Chapter 2: Using the Wheel Pilot                                                        25


2.5 Using Wind Vane mode
                  Note: You can only use Wind Vane mode if the wheel pilot is
                  connected to a suitable wind sensor/instrument providing wind
                  direction data.
                  To use Wind Vane mode, the wheel pilot must receive wind
                  information from one of the following sources:
                     SeaTalk wind instrument
                     NMEA wind instrument
                     Raymarine pushpit wind vane (part number: Z159) connected via
                      the supplied SeaTalk interface




                                                                                             2 Using the Wheel Pilot
                  In 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 short-term changes in
                  wind direction, yet still tracks real wind shifts as subtle as 1.

       Selecting Wind Vane mode
                  From Standby mode or Auto mode, press STANDBY and AUTO
                  together to select Wind Vane mode. The wheel pilot will then
                  maintain the current apparent wind angle.




                            and

       Operating hints for Wind Vane mode
                     WindTrim filters the wind vane output. This provides optimum

                     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 tolerated.
                     It is important to minimize the amount of standing helm through
                      careful sail trimming and positioning of the mainsheet traveller.
                     It is recommended that the headsail and mainsail are reefed a little
                      early rather than too late.

Chapter 3: Maintenance & Fault Finding
                 This chapter provides information about maintaining your wheel
                 pilot system, obtaining product support and solving common
                 problems.

3.1 General maintenance
                 CAUTION:
                 The control unit does not contain any user serviceable parts.
                 It should be repaired only by authorized Raymarine service
                 representatives.

                 Display condensation
                    In certain conditions, condensation may appear on the LCD
                     window. This will not harm the unit, and can be cleared by
                     switching on the illumination for a while.

                 Routine cabling checks
                    Make sure all connections are firmly attached.




                                                                                             3 Maintenance & Fault Finding
                    Examine the cable for signs of wear or damage  replace any
                     damaged cables.

                 Cleaning the wheel pilot
                    If the wheel drive or control unit are dirty, wipe them with a clean,
                     damp cloth.
                    Never use chemical or abrasive materials.

                 EMC advice
                    When powered up, all electrical equipment produces
                     electromagnetic fields. These can cause adjacent pieces of
                     electrical equipment to interact with one another, with a
                     consequent adverse effect on operation.
                    To minimize these effects and enable you to get the best possible
                     performance from your Raymarine equipment, guidelines are
                     given in the installation instructions, to enable you to ensure
                     minimum interaction between different items of equipment,
                     i.e. ensure optimum Electromagnetic Compatibility (EMC).

                                              Always report any EMC-related problems to your nearest
                                               Raymarine dealer. We use such information to improve our
                                               quality standards.
                                              In some installations, it may not be possible to prevent the
                                               equipment from being affected by external influences. In general
                                               this will not damage the equipment but it can lead to spurious
                                               resetting action, or momentarily may result in faulty operation.

                                3.2 Product support
                                           Raymarine products are supported by a worldwide network of
                                           distributors and Authorized Service Representatives.
                                           Before you consider returning the autopilot, make sure that the power
                                           supply cable is sound and that all connections are tight and free from
                                           corrosion. If the connections are secure, refer to the following Fault
                                           Finding section.

Chapter 4: Installing the Wheel Pilot
4.1 Planning the installation
                   Before you start installing your wheel pilot system, read through the
                   following information and the relevant installation sections in this
                   chapter.
                   Cabling guidelines
                      consider how you will run cables to and from each component
                      avoid running cables through bilges where possible
                      avoid running cables close to fluorescent lights, engines, radio
                       transmitting equipment etc.

                   EMC installation guidelines
                   All Raymarine equipment and accessories are designed to the best
                   industry standards for use in the recreational marine environment.
                   Their design and manufacture conforms to the appropriate
                   Electromagnetic Compatibility (EMC) standards, 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 product.
                   The 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 equipment.
                   For optimum EMC performance, we recommend that:
                                                                                               4 Installing the Wheel Pilot




                      Raymarine equipment and cables connected to it are:
                        At least 3 ft (1 m) from any equipment transmitting or cables
                          carrying radio signals e.g. VHF radios, cables and antennas.
                          In the case of SSB radios, increase the distance to 7 ft (2 m).
                        More than 7 ft (2 m) from the path of a radar beam. A radar
                          beam can normally be assumed to spread 20 degrees above
                          and below the radiating element.

                                       The equipment is supplied from a separate battery from that used
                                        for engine start. Voltage drops below 10 V, 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 mode.
                                       Raymarine 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 manual.
                                       If a suppression ferrite is attached to a cable, this ferrite should not
                                        be removed. If the ferrite needs to be removed during installation

       Mounting procedure
                   The control unit slots into a permanently mounted socket sited in the
                   cockpit. It contains a gimballed fluxgate compass and therefore has
                   some restrictions on mounting position.




                                                                                                  4 Installing the Wheel Pilot




                                                                                      D5629-1



                   The control unit should be sited
                      where it can be operated easily from the steering position.
                      at least 80 cm (2.5 ft) away from the main steering compass to
                       avoid deviation of both compasses
                      as far away from other magnetic or iron devices as practical (to
                       avoid compass deviation)

                                           Having selected the best mounting site, secure the mounting socket to
                                           a convenient wooden or glass fibre surface using the self tapping
                                           screws provided.
                                           The mounting surface should not be more than 10 from vertical. This
                                           will allow correct compass operation with the boat heeled at an angle
                                           of up to 40.




                                                                               10 maximum

                                    Cabling and socket installation
                                           Both power and SeaTalk data are supplied to the control unit via a
                                           custom waterproof plug and socket. The plug comes ready assembled
                                           and the socket can be mounted in the cockpit area adjacent to the
                                           autopilot. The control unit supplies power to the wheel drive unit via
                                           a cable plugged into the underside of the control unit.

                                           Power supply
                                              The wheel pilot requires its own dedicated power supply  it
                                               cannot source its power from SeaTalk.
                                              The power supply should be taken directly from the boat's central
                                               distribution panel and protected with a 12 A fuse or equivalent

                   IMPORTANT:
                   Correct power cable size is critical for correct autopilot
                   operation. If in doubt, use a heavier gauge cable than specified.
                   A lighter gauge cable may cause a voltage drop between the
                   supply and the autopilot. This will reduce the power at the wheel.

                   SeaTalk cabling
                   The ST3000 control unit is SeaTalk compatible. It can receive and
                   transmit information to other instruments and autopilot control units
                   via the SeaTalk bus.
                   To connect the ST3000 control unit to the SeaTalk bus you will need
                   a suitable SeaTalk interface cable (part numbers: D229 flat moulded
                   plug, D179 male round plug, D181 female round plug) or a plugged
                   SeaTalk cable with one end cut off:
                       plug one end of the cable to the last instrument or control unit
                                                                                                              4 Installing the Wheel Pilot




                       connect the cores at the other end to the SeaTalk socket as shown
                   CAUTION:
                   The fuse on the control unit power supply is too large to offer safe
                   protection to the SeaTalk bus. You MUST protect the power
                   supply for the SeaTalk 12 V (red) line with a 5 A fuse (or
                   equivalent circuit breaker).

                   NMEA cabling
                   To connect NMEA equipment, you will need to use a
                   SeaTalk/NMEA interface (part number: E85001) to convert the

                                    Mounting the socket
                                          To mount the SeaTalk socket:
                                          1. Fix the template (supplied at the end of the handbook) onto the
                                             bulkhead at the selected socket location
                                          2. Carefully drill the 18 mm (23/32 in) clearance hole and 2.4 mm
                                             (3/32 in) pilot holes, then remove the template.
                                          3. Fit the plug cap to the socket body.
                                          4. Locate the O-ring seal into the groove between the plug cap and
                                             socket body.
                                          5. Cut and strip back the power cables and SeaTalk cables (if fitted).
                                          6. Thread both cables through the bulkhead hole and connect to the
                                             relevant pins on the socket.
                                          7. Attach the socket to the bulkhead using the two self tapping
                                             screws supplied.
                                          8. Secure the cables to the bulkhead.

Chapter 4: Installing the Wheel Pilot                                                     43


4.3 Drive unit installation
                   The Raymarine 3000 wheel drive is designed to operate with steering
                   systems having between 1 and 3 turns lock to lock. Steering systems
                   with more than 3 turns lock to lock may cause impaired steering
                   performance due to reduced rate of rudder application.
                   Lost motion in the steering system must not exceed 2% of total
                   movement. This is equivalent to 15 of free wheel movement for a
                   system with 2 turns lock to lock. If lost motion exceeds this level it
                   must be corrected, otherwise steering performance will be impaired.

       Attaching the wheel drum
                   The drum is clamped to the wheel spokes using the three U-bolts
                   provided. You can use the standard wheel drum on wheels with 3, 5
                   or 6 spokes:
                      A holes: 3 and 6 spoke wheels
                      B holes: 5 spoke wheels
                      C holes: 3, 5 or 6 spoke wheels with spoke diameter of 26 mm
                       (1 in)  these holes require special U-bolts (part number D103)




               A                            B                              C

                                                                                                4 Installing the Wheel Pilot



                   Note: For 4 spoke wheels, contact Raymarine Technical Services to
                   obtain a specially drilled drum.
                   Position
                   Ideally, you should fit the wheel drum behind the wheel (i.e. between
                   the wheel and the pedestal, as shown in the following diagram). To do
                   this, you will need to remove the wheel.
                   If there is insufficient clearance behind the wheel, you can fit the
                   wheel drum in front of the wheel.

                                           The drum comes with three complete sets of spacers to fit differing
                                           spoke diameters.The spoke diameter is marked alongside each

                                           Use the U-clamps to secure the wheel drum to the wheel spokes:
                                               roughly position the drum on the wheel and then lightly tighten
                                                the clamp nuts
                                               check if the drum is central by spinning the wheel
                                               re-position the drum until it is central  with a total run-out less
                                                than 2 mm (1/16 in)
                                               when the drum is central on the wheel, tighten the clamp nuts

                                           The drive unit is normally mounted on the cockpit side wall. If the
                                           standard belt does not allow a convenient location for the mounting
                                           clevis, you will need to purchase one of the alternative belt sizes to

                   Attaching the mounting clevis
                   1. Fit the mounting clevis to the drive unit using the pin provided.
                      Then loop the belt drive over the drum and the drive sprocket.
                   2. Rotate the clutch lever fully clockwise against its stop (i.e. to the
                      `tight belt' position) and then offer the clevis against the vertical
                      side-wall.
                   3. Move the clevis down against the side wall until the belt is just
                      taut. Then adjust the fore-and-aft position of the clevis until the
                      belt lies parallel to the wheel. To help check if the belt is running
                      parallel, use a long straight edge such as a sail batten.

                                    4. When you have determined the correct position for the clevis,
                                       carefully draw around its base.




                                                                                                    D5639-1



                                    5. Remove the drive unit and draw around the inside of the
                                       elongated fixing holes on the clevis.




                                                                                                    D5640-1

                                    6. Drill two 8 mm ( /16 in) clearance holes for the clevis fixing bolts
                                       at the lower end of each elongated hole position. This allows the
                                       belt to be subsequently tightened if necessary.
                                    Note: Before drilling the holes, check that you have access to the
                                    other side of the mounting wall to attach the nuts!

                   7. Bolt the mounting clevis into position with the fixing bolts
                      positioned mid-way in the elongated holes. This will ensure that
                      the belt is taut when you rotate the clutch lever fully clockwise to
                      tension the belt.

                   8. Re-assemble the complete drive system and then check the clutch
                      operation. If necessary, reposition the clutch lever on the splined
                      eccentric bush to ensure that the lever can rotate 180 without
                      obstruction.
                   9. Check the belt tension:
                       when the belt is tensioned by rotating the clutch lever fully
                         clockwise, you should be able to back-wind the drive unit by
                         slowly rotating the wheel. If belt slip occurs, increase belt
                         tension by reclamping the clevis in a slightly lower position.
                       when the clutch lever is rotated fully anti-clockwise the wheel
                         drum should slip easily against the belt
                       do NOT over tighten the belt

                                    3. Rotate the clutch lever fully clockwise against its stop (to the
                                       `tight belt' position), then offer the bracket against the pedestal.

                   4. Move the bracket down against the pedestal until the belt is just
                      taut. The slide the pedestal bracket around the pedestal and
                      rotating the clevis bracket to ensure that the belt runs parallel to
                      the wheel.

                                    5. When you have determined the correct position for the pedestal
                                       bracket, carefully draw around its base and inside its the
                                       elongated fixing holes.




                                                                                                  D5644-1



                                    6. Tighten the clevis mounting bolts.
                                    7. Drill four 4.3 mm (11/64in) pilot holes for the pedestal bracket
                                       fixing screws at the lower end of each elongated hole position.
                                       This allows the belt to be subsequently tightened if necessary.

                   8. Screw the pedestal bracket into position with the self tapping
                      screws mid-way in the elongated holes. This will ensure that the
                      belt is taut when you rotate the clutch lever fully clockwise to
                      tension the belt.




                                                                                   D5646-1



                   9. Re-assemble the complete drive system and then check the clutch
                       operation. If necessary, reposition the clutch lever on the splined
                       eccentric bush to ensure that the lever can rotate 180 without
                       obstruction.
                   10. Check the belt tension:
                        when the belt is tensioned by rotating the clutch lever fully
                          clockwise, you should be able to back-wind the drive unit by
                                                                                                  4 Installing the Wheel Pilot



                          slowly rotating the wheel. If belt slip occurs, increase belt
                          tension by reclamping the clevis in a slightly lower position.
                        when the clutch lever is rotated fully anti-clockwise the wheel
                          drum should slip easily against the belt
                        do NOT over tighten the belt

                                    Mounting on transverse bulkheads
                                    If the steering wheel is mounted on a transverse bulkhead, you will
                                    need to make special provision to mount the drive unit. You can
                                    obtain as L-bracket (part number: D047) from your Raymarine dealer
                                    to mount the clevis on the bulkhead as shown.
                                    Note: You may also need to make a hardwood spacer to ensure
                                    correct belt alignment with the wheel drum.

                                    Alternative drive unit mounting positions
                                    The wheel drive unit may be positioned on either the port or starboard
                                    side of the wheel. The fluxgate compass is calibrated to give correct
                                    steering sense when the drive unit sprocket is facing aft. Access to the
                                    clutch lever is also easier when the drive unit is mounted this way
                                    round.
                                    However, if an obstruction prevents you from mounting the drive unit
                                    with the drive sprocket facing aft, you can mount it with the sprocket
                                    facing forward. In this case, you will need to re-adjust the motor drive
                                    sense to regain correct steering  see page 53.

Chapter 5: Commissioning the Wheel Pilot




                                                                                             5 Commissioning the Wheel Pilot
                 This chapter explains how to commission your wheel pilot after
                 installation. This consists of a number of simple functional tests
                 followed by a short sea trial.

5.1 Functional tests
       Switch on
                 1. Switch on the main power breaker.
                 2. The control unit should beep and display the pilot type (ST3000).
                 3. Within 2 seconds, the display should show a flashing `C' followed
                    by the compass heading (for example, C 234). This shows the
                    autopilot is active.
                 Note: If the wheel pilot does not beep or display the compass
                 heading, please refer to the Fault Finding section (see page 30).

       Operating sense
                 The operating sense defines the direction the wheel pilot will apply
                 helm when a course change key is pressed or the boat goes off course.
                 To check the operating sense:
                 1. Turn the clutch lever fully clockwise to engage the clutch.
                 2. Press +10.
                 3. The wheel should move to produce a turn to starboard.




                                           +


                                                                                  D5648-1


                 4. If the wheel movement produces a turn to port, refer to the
                    following instructions on reversing the operating sense.
                 Note: You should only need to reverse the operating sense if you have
                 installed the drive with the sprocket facing forward (see page 52).

                                              Reversing the operating sense
5 Commissioning the Wheel Pilot




                                              If necessary, reverse the operating sense as follows:
                                              1. Press -1 and +1 together for 5 seconds.
                                              2. The display shows the new operating sense (port or starboard) for
                                                 5 seconds, and then the autopilot reverts to normal operation.

                                       Checking the navigation interface
                                              If you have connected the wheel pilot to a navigator, check the
                                              interface as follows:
                                              1. Set up a track on the navigator to give a Cross Track Error
                                                 between 0 nm and 0.3 nm.
                                              2. Enter Auto mode by pressing AUTO.
                                              3. Enter Track mode by pressing -10 and +10 together.
                                              4. After 3 seconds, the pilot should automatically scroll through the
                                                 navigation displays:


                                                                                     Locked heading

                  Track data error

                                                               The wheel pilot displays this message if you
                                                               select Track mode when the navigator has

                                                               the navigator regains its fix.

       Checking the wind instrument interface
                 If you have connected the wheel pilot to a wind instrument, check the
                 data link as follows:
                 1. Press STANDBY and AUTO together.
                 2. The wheel pilot should display a `W' and the locked heading.




                            and




                                                                                                        D5616-1


                 If the display continues to show a flashing `C' and the current heading,
                 the wheel pilot is not receiving any wind data. The most likely reason
                 is a cabling error  either open circuit, short circuit or wires reversed.

       Checking the SeaTalk interface
                 If you have connected the wheel pilot to other instruments or control
                 units via SeaTalk, check the link as follows:
                 1. Press STANDBY on the ST3000 control unit.
                 2. Select display illumination level 0 (LAMP 0) on any other SeaTalk
                    instrument or autopilot control unit.
                 3. The ST3000 control unit should immediately respond by
                    switching off its display illumination. If the illumination does not
                    switch off, there is a cabling fault between the ST3000 and the
                    SeaTalk instruments.

5 Commissioning the Wheel Pilot




                                              CAUTION:
                                              Failure to carry out the sea 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 built-in calibration capability so you can
                                              fine-tune it to suit your boat, its steering system and its dynamic
                                              steering characteristics.
                                              As supplied from the factory, the autopilot is calibrated to provide
                                              safe, stable control for most boats.
                                                 Do not attempt to make any permanent changes to the
                                                  recommended calibration values until you have completed the
                                                  sea trial.
                                                 You must carry out the initial sea trial in conditions of light wind
                                                  and calm water  so you can assess the autopilot's performance
                                                  without the influence of strong winds or large waves.
                                              Note: At any time during the sea trial, you can disengage the
                                              clutch lever to return to hand-steering.

                                              Before starting the sea trial
                                              Before carrying out the sea trial, you should:
                                                 check the calibration settings and, if necessary, reset them to the
                                                  default values (see page 63)
                                                 check the installation to make sure that it is not affected by radio
                                                  transmissions, engine starting, etc.

5.3 Adjusting autopilot performance




                                                                                                 5 Commissioning the Wheel Pilot
                 The 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
                 autopilot's steering characteristics.
                 The following test will determine whether the rudder gain is set too
                 high or too low.
                 1. In clear water and with the autopilot in Auto mode, alter course to
                    starboard by 40 by pressing +10 four times.
                     At cruising speeds, a course change of 40 should result in a
                        crisp turn followed by an overshoot of no more than 5.
                        If this occurs the rudder gain is set correctly.
                     If rudder gain is too high, the 40 course change will result in a
                        distinct overshoot of more than 5 (A).
                        Correct this oversteer by reducing the rudder gain setting.
                     If rudder gain is too low, the boat's steering performance will
                        be sluggish  it will take a long time to make the 40 turn and
                        there will be no overshoot (B).
                        Correct this understeer by increasing the rudder gain setting.

                                       You 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 tear.

Chapter 6: Adjusting Wheel Pilot Settings
6.1 Introduction
                  The wheel pilot is calibrated at the factory to provide stable
                  performance for most boats. However, you can fine tune many of the
                  calibration features to match your personal preferences, and the type
                  of boat and steering system.
                  Note: You should carry out an initial sea trial before adjusting any of
                  the calibration features.




                                                                                                6 Adjusting Wheel Pilot Settings
                  You might need to adjust the wheel pilot calibration settings if:
                     the pilot does not maintain a selected heading
                     the rudder activity is too high or the course keeping is not tight
                      enough.
                     the boat appears to be unstable on Northerly headings (or
                      Southerly headings in the southern hemisphere)
                     you operate in Track Control mode without a speed instrument
                     you wish to change the Off Course alarm angle
                  The calibration menu allows you to adjust the following parameters
                  from their factory default settings:
                     rudder gain
                     average cruise speed
                     off course alarm limit
                     variation
                     Northerly/Southerly turning error compensation
                     boat's current latitude

                                   6.2 Calibrating the wheel pilot
                                        Calibration Level 1: Rudder gain
                                               Use Calibration Level 1 to adjust the rudder gain. This must be set
                                               when your boat is under way, as described on page 59.

                                        Calibration Level 5: Cruise speed
                                               Use Calibration Level 5 to set the boat's normal cruising speed for
                                               operation in Track mode.
                                               When interfacing with a navigation system, the wheel pilot uses the
6 Adjusting Wheel Pilot Settings




                                               boat's average cruising speed to perform track calculations.
                                               Note: If a SeaTalk speed instrument is connected, boat speed data
                                               will be transmitted directly to the autopilot.

                                        Calibration Level 6: Off course alarm angle
                                               Use Calibration Level 6 to set the off course alarm angle. This alarm
                                               warns you if the autopilot is unable to maintain its set course.
                                               The off course alarm operates if the autopilot strays off course, by
                                               more than the set value, for more than 20 seconds.
                                               You can set the limit in 1 increments between 15 and 40.

       Calibration Level 9: Magnetic variation
                  Use Calibration Level 9 to input the level of magnetic variation
                  present at the boat's current position.
                     -ve variation = west
                     +ve variation = east
                  The wheel pilot transmits this value onto the SeaTalk bus, so it can be
                  picked up by other SeaTalk instruments.

       Calibration Level 10: Heading error correction




                                                                                                6 Adjusting Wheel Pilot Settings
                  Use Calibration Level 10 to switch on Northerly or Southerly heading
                  error correction:
                     0 = Off
                     1 = Northern Hemisphere, 2 = Southern Hemisphere
                  You might notice 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 hemisphere).
                  This is caused by the increasing angle of dip of the earth's 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 equator.
                  With 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.

                                        Calibration Level 11: Boat's current latitude
                                               When you have switched on heading error correction (Level 10), you
                                               need to use Calibration Level 11 to input the boat's current latitude
                                               (to the nearest degree).
                                               Set the latitude using the -1, +1, -10 and +10 keys.
                                               Note: If the correction is switched off in Calibration Level 10 (i.e. set
                                               to `0'),Level 11 will be omitted. When you press the AUTO key in
                                               Calibration Level 10 you will advance to Level 13.

                                               You can prevent unauthorized access to calibration as follows:
                                               1. Press and hold -1 and STANDBY together for 10 seconds until the
                                                  display shows CAL OFF:

                                               2. Toggle the calibration access between OFF and On using the -1 and
                                                  +1 keys.
                                               3. Store the setting by pressing -1 and standby for 10 seconds until
                                                  the wheel drive returns to normal operation.

responsibility for damage incurred during installation.
This Warranty does not cover routine system checkouts or alignment/calibration, unless required by

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
