Important Information
Safety notices
      WARNING: Navigation aid
      Although we have designed this product to be accurate and
      reliable, many factors can affect its performance. Therefore, 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.
    CAUTION: Calibration
    When supplied, this product is calibrated to default settings which
    should provide initial stable performance for most boats. To ensure
    optimum performance on your boat, the commissioning procedures
    (in the SPX-5R Drive Installation & Setup Guide) must be completed
    before this product is used.
    Your Raymarine SPX-5R Drive system 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 members of crew know how to disengage the autopilot.
    · Regularly check for other boats and any obstacles to navigation ­ no matter how
        clear the sea appears, 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.

EMC Conformance
    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.

Chapter 1: Basic Operation
1.1 Introduction
    The SmartPilot X-5 (SPX-5R) Drive system is intended for use as an aid to steering
    leisure marine craft with a fully-laden displacement up to a maximum of:
    · 4400 pounds (2000 kg) for mechanically steered craft.
    · 7500 pounds (3500 kg) for power steered craft.

                                                                             Drive unit




                                 Fluxgate
                                 compass


                                                                                      D10702-2


    Your SPX-5R Drive system is controlled by a Raymarine ST6002 Pilot Controller
    (supplied), and operates in the following modes:
    · Standby: SmartPilot off. You have manual control of the boat.
    · Auto: The SmartPilot steers the boat to maintain a locked heading.
    · Track: The SmartPilot steers the boat to maintain a track between two waypoints
       created on a navigation aid.
    The SPX-5R Drive system also provides:
    · Enhanced course keeping using AST (Advanced Steering Technology).
    · AutoLearn, Raymarine's self-learning calibration system.

    Extended systems
    You can connect the Pilot Controller to other Raymarine SeaTalk equipment so it can
    send and receive SeaTalk data. The Pilot Controller uses:
    · Waypoint information from a SeaTalk navigation instrument to provide track
       control.
    · Boat speed information from a SeaTalk speed instrument to optimize track-
       keeping performance.
    You can also use the SPX-5R Drive system with SeaTalkng (refer to the SeaTalkng
    Reference Manual), or with any navigator or instrument that transmits National
    Marine Electronics Association (NMEA) 0183. The SPX-5R Drive system is also
    compatible with NMEA2000 data, accessed via SeaTalkng.
    The Pilot Controller can display SeaTalk and NMEA instrument data in a user-defined
    selection of data pages.

    For further information on other connections to your system refer to the SmartPilot
    X-5R Drive Installation & Setup Guide.

1.2 Using the control unit
    Switching on and off
    When power is applied to the Pilot Controller, you can use the        disp button to
    switch it off and on as follows:
    · To switch the Pilot controller off, ensure it is in the Standby mode, then hold down
            disp for approximately 5 seconds. After this time, a switch off count down of
        4 seconds occurs. Keep         disp pressed during this period, to switch off the
        instrument.
    · To switch the instrument back on, hold down           disp for approximately 1 second.
    If power is not applied, the Pilot Controller buttons have no effect.
    Notes: (1) Each time power to the Pilot Controller is switched on, the controller is initially in the
                  on condition. You do not need to use         disp to switch the controller on.
             (2) When the controller is on, the operation of       disp initiates other operating
        functions, as described below.

    Start-up mode
    The SPX-5R Drive system always powers up in Standby mode with the Pilot
    Controller display showing the boat's current compass heading.

    Keypad functions
    The SPX-5R Drive system is controlled by button presses at the Pilot Controller.
    Button operation is confirmed with a short beep. Single-button and dual-button
    operations are used.

1.3 Using the SPX-5R Drive system to steer your boat
        WARNING: Maintain a permanent watch
        Automatic course control makes it easier to steer a boat, but it is
        NOT a substitute for good seamanship. ALWAYS maintain a
        permanent watch by the helm.

    Emergency release pin
    In the unlikely event of a steering failure, remove the release pin as shown to take
    manual control of the vessel.




    After removing the pin the drive and attached part of the torque restraint will rotate.
    Hold the torque restraint away from the dashboard to avoid contant with any
    protruding objects.
    Replacing the pin after use
    ·   Inspect the Pin and R-Clip for any wear or damage prior to re-use.

    Standby mode - steering by hand
    At any time you wish to take manual control of the vessel and disengage the autopilot:
    ·   press the standby key.
Chapter 1: Basic Operation                                                                   5




                                                            TRUE




                                                                                 D10524-1


      In Standby mode:
      · You have manual control of the boat.
      · The display shows STANDBY and the boat's current compass heading.

      Using the autopilot to steer to a heading
      Before engaging the autopilot, ensure you can steer the boat satisfactorily by hand,
      then steady the boat on the required heading.
      To engage the autopilot for automatic steering:
      · Press the auto key.
      The SPX-5R Drive system will steer the boat on the chosen heading, which is shown
      on the display. This mode is also known as "point-and-shoot".




                                                            TRUE




                                                                                 D3560-6



      Changing course in Auto mode
      In Auto mode, use -1, -10, +1 and +10 to change the locked heading, in either 1° or
      10° steps.Use -1 or -10 to apply changes to port and +1 or +10 for changes to
      starboard. For example: press -10 three times for a 30° course change to port.

    AutoTurn
    In Auto mode, you can carry out an AutoTurn of 90° by pressing -1 and -10 for an
    AutoTurn to port, or +1 and +10 for an AutoTurn to starboard.

    Avoiding obstacles
    When your boat is under autopilot control, you can change course to avoid the
    obstacle, then resume your previous course. You can either:
    · Manually steer away from the obstacle immediately. This is especially useful
       when a quick course change is required, e.g. in an emergency situation.
       or
    · Use -1, -10, +1 and +10 to change the locked heading.


                                                                    Obstacle

                                                                                 course


                                                            Dodge

                                                                                          D10692-1


    Steering away
    The preferred method for steering away from obstacles is:
    1. Press standby, to return to Standby mode.
    2. Manually turn the wheel to steer away from the obstacle.
    3. Press auto to re-engage Auto mode
    If you do not have time to engage Standby mode (e.g. in an emergency), manually
    turn the steering wheel to steer away from the obstacle, whist still in Auto mode. When
    you have passed the obstacle, press standby then auto, to re-engage Auto on the
    previous locked heading.
    Selecting a change of course
    1. Use -1, -10, +1 and +10 to select a change of course in the appropriate direction.
       For example, press -10 three times for a 30°dodge to port.
    2. When you are safely clear of the obstacle, reverse the previous course change.
       For example, press +10 three times to reverse a 30°dodge to port.

    Off Course alarm
    If you have been off course from the locked heading for longer than 20 seconds, an
    alarm sounds and the Pilot Controller shows whether the deviation is to port or
    starboard.
Chapter 1: Basic Operation                                                                            7




                                                           = deviation to port
                                                           = deviation to starboard



                                                                                        D3315-5


      To cancel an Off Course alarm, press standby to return to manual steering. If the
      heading recovers or if you change course, the alarm clears automatically.
      Note: The default off course angle is set at 20º. You can adjust this angle in Dealer Calibration
      (see SmartPilot X-5R Drive Installation & Commissioning Guide).


1.4 Adjusting pilot performance
      The principal method of adjusting the performance of an SPX-5R Drive system is by
      changing the response level. This controls the relationship between the course
      keeping accuracy of the SPX-5R Drive system, and the amount of helm/drive activity.
      Changing the response level should be the only adjustment you need to make to your
      SPX-5R Drive system on a regular basis.
      When you first turn on your SPX-5 Drive system after installation, the response will
      initially be set to the default level of 5, but you can change this level in User Calibration
      (refer to your SmartPilot X-5R Drive Installation & Setup Guide for details). Changes
      made using user Calibration will be retained when the SPX-5R Drive system is
      switched off.
      You can also make temporary adjustments to the response level to quickly match
      performance to changing conditions. Note however that these temporary changes to
      response level will be lost when the system is powered off, with the default value
      being reapplied when the system is next switched on.

      Response levels
      As a general rule, higher response values give tighter course keeping (e.g. for
      pilotage in confined and sheltered waters). Lower values reduce drive activity and
      conserve battery power.
      The SPX-5R Drive system has nine levels of response:
      · Levels 9 to 7 give the tightest course keeping and greatest rudder activity (and
         power consumption). This can lead to a rough passage in open waters as the
         SPX-5R Pilot may `fight' the sea.
      · Levels 6 to 4 should give good course keeping with crisp, well controlled turns
         under normal operating conditions.
      · Levels 3 to 1 minimize the amount of pilot activity. This conserves power, but may
         compromise short-term course-keeping accuracy.

       control units will also change.
Chapter 1: Basic Operation                                                                             9


      3. The display automatically returns to the previous mode if you do not press a
           button for 10 seconds.
      If you press another mode button within 10 seconds you will select the associated
      mode. For example: auto selects Auto mode, standby selects Standby mode.
      Notes: (1) You can also adjust the lighting level from other SeaTalk instruments or control
                  units.
              (2) When you switch off, any changes you have made to the lighting level will be lost.


      Contrast
      To set the display contrast level:
      1. With the autopilot in Standby mode, hold down disp for one second to access the
           LAMP screen.
      2. Hold down disp for one second again, to display the CONTRAST screen.
      3. Use +1 and -1 to set the required contrast level (from 1 to 15).
      4. The display automatically returns to the previous mode if you do not press a
           button for 10 seconds.
      If you press another mode button within 10 seconds you will select the associated
      mode. For example: auto selects Auto mode, standby selects Standby mode.

1.6 Data pages
      A series of data pages on the Pilot Controller enables you to quickly monitor various
      information from your SPX-5R Drive system. To access these data pages:
      1. Press disp to access the first data page.
      2. Press disp again to cycle the next data page, then continue this process to reach
           the page you want.
      3. When all pages have been displayed and you press disp again, the display
           returns to the current SPX-5R Drive system mode screen (for example, AUTO).
      When you first use your SPX-5R Drive system, four data pages are available, as in the
      following illustration, but you can configure up to fifteen data pages during Display
      calibration, as detailed in the SPX-5R Drive Installation & Commissioning Guide.
10                                                     SmartPilot X-5R Drive Operating Guide

     If the required information is not available for any data page, dashes are displayed.
     Most data pages show repeated data so are for information only; you cannot adjust
     the values on them. An exception to this is the RESPONSE page, where you can adjust
     the value using the -1 and +1 buttons.

     Waypoint names
     If waypoints have been given names, the Pilot Controller will display them on the
     Cross Track Error (XTE), Bearing To Waypoint (BTW) and Distance To Waypoint
     (DTW) data pages:
     · Waypoint names of five characters or less are displayed together with the page
         name (as shown by screen A below).
     · Waypoint names of more than five characters alternate with the page name (as
         shown by screen B below).
     · If a waypoint name has more than nine characters, the display only shows the first
         nine characters.




                               TRUE                                         TRUE

1.7 Alarms
     The SPX-5R Drive system supports the alarms listed on the following pages. When
     an alarm occurs, a beep sounds and the appropriate alarm message is displayed.
Chapter 1: Basic Operation                                                                         11


      Responding to alarms
      ·   Unless otherwise stated, if an alarm occurs, press standby to clear the alarm and
          return to hand steering.
      ·   If more than one alarm occurs, as each alarm is cleared, the next is displayed.

       Message         Description and possible actions

       LARGE XTE       Large cross track error
                       Occurs if the cross track error exceeds 0.3 nm. The alarm clears if the head-
                       ing recovers.

       MOB             Man OverBoard alarm
                       The SPX-5R Drive system activates the Man Overboard alarm if it receives
                       a man overboard (MOB) message from another instrument on the SeaTalk
                       system. It displays the text MOB instead of the waypoint number on the
                       XTE, DTW and BTW data pages.
                       If the autopilot is in Track mode, it will sound the Waypoint Advance alarm
                       to notify you of the change in waypoint.

       NEXT WPT        Waypoint advance alarm
                       The SPX-5R Drive system activates the Waypoint Advance alarm when-
                       ever the target waypoint changes. This occurs when:
                       · you select automatic acquisition by pressing track from Auto
                       · you request waypoint advance by pressing track for 1 second in Track
                           mode (with SeaTalk navigators only)
                       · the boat arrives at the target waypoint and the navigator accepts the next
                           waypoint
                       · you activate the Man Overboard (MOB) function in Track mode
                       When the alarm sounds, the pilot continues on its current heading but dis-
                       plays:
                       · the bearing to the next waypoint
                       · the direction the boat will turn to take up that bearing

       NEXT WPT        Responding to a Waypoint Advance alarm
       (continued)     To respond to a Waypoint Advance alarm:
                       · check that it is safe to turn onto the new track, then press track to accept
                           the waypoint advance
                       · alternatively, you can cancel the alarm without accepting the waypoint
                           advance by pressing: standby to return to hand steering, or auto to
                           return to Auto mode.
                       Note: Waypoint advance only operates if the SPX-5R Drive system is re-
                       ceiving valid bearing to waypoint and waypoint number information.

       OFFCOURSE       Off course alarm
       (PT or Stb)     Occurs if the vessel has been off course from the locked heading for longer
                       than 20 seconds.
                       · PT = Deviation to port
                       · Stb = Deviation to starboard
                       You can adjust the specified alarm angle in Dealer setup, see your Com-
                       missioning guide for details.
                       If this happens frequently you should review autopilot performance.

       SHALLOW         Shallow alarm
                       The SPX-5R Drive system activates the Shallow alarm if it receives a shal-
                       low depth alarm via SeaTalk:
                       · press standby or disp to cancel the alarm

1.8 Response setup
     The response level controls the relationship between course keeping accuracy and
     the amount of helm/drive activity. User setup functions are accessed using a User
     calibration mode. Information on other setup functions is given in the SmartPilot X-5R
     Drive Installation & Setup Guide.
     Note: You can also make temporary changes to response during normal operation, as de-
     scribed earlier in this Chapter.

     Screen Text            Options

     RESPONSE               Range = 1 to 9 .
                            Levels 9 to 7 give the tightest course keeping and greatest rudder
                            activity (and power consumption). This can lead to a rough passage
                            in open waters as the SPX Wheel system may `fight' the sea.
                            Levels 6 to 4 should give good course keeping with crisp, well
                            controlled turns under normal operating conditions.
                            Levels 3 to 1 minimize the amount of pilot activity. This conserves
                            power, but may compromise short-term course-keeping accuracy.
Chapter 1: Basic Operation                                                             13


      Accessing response setup
      You can access the User calibration mode only from Standby mode, so to set the
      response level:
      1. Ensure the SPX-5R Drive system is in Standby mode, then hold down standby
         for 2 seconds. The display will change to show DISPLAY CAL.
      2. Press disp once. The display will now show USER CAL.
      3. Press auto to enter User calibration.
         The Response setup page is displayed.
      4. To access other User calibration pages, press disp to scroll through the
         calibration functions (described below).
      5. Use the -1, +1, -10 and +10 buttons to change the value of each function you want
         to change.
      6. When you have made all the changes you want to make, hold down standby for
         two seconds to exit calibration mode and save changes.

Chapter 2: Using Track mode
2.1 Overview
   Your SPX-5R Drive system provides a Track mode, to enable you to automatically
   follow a route (or track), set on your chartplotter or GPS.
   A track is a predefined path through a series of waypoints with each "track leg" being
   a straight line between 2 consecutive waypoints.




                                                                   Waypoint


                                                  Track leg




                                                                                       D10915-1
   In Track mode, the SPX-5R Drive system will make any course changes necessary to
   keep your boat on the required track, and automatically compensate for tidal streams
   and leeway.

   Requirements for Track mode
   To operate in Track mode, the SPX-5R Drive system must receive route information
   from a suitable navigation system, such as:
   · A SeaTalk compatible chartplotter or GPS unit.
   · An NMEA 0183 or NMEA2000 compatible chartplotter or GPS unit.
   · A SeaTalkng compatible chartplotter.
   Refer to the SmartPilot X-5R Drive Installation & Commissioning Guide for
   connection details.

   Starting position and heading
   Before entering Track mode, ensure that the boat is as close as possible to the actual
   track and course heading (see Track keeping & Cross Track Error on page 17.). When
   you enter Track mode, the SPX-5R Drive system will steer the boat onto the required
   track.

2.2 Procedures
     Entering track mode
     Starting with the SPX-5R Drive system in Auto mode and your chartplotter or GPS set
     to follow a route, enter track mode as follows:
     1. Press track to enter Track mode.
     2. The autopilot will sound an alarm and the display will show information regarding
         the next planned waypoint.
     3. Check that it is safe for the boat to turn onto the new course, then press track
         again.
         The SPX-5R Drive system will turn the boat onto the new course and the display
         will show the heading required to achieve the required track.
     Note: If the boat is more than 0.3 nm from the track, a Large Cross Track Error warning will
     sound (see page 18).

     Leaving Track mode
     You can leave Track mode at any time. To do this, either:
     · Press auto to return to Auto mode.
        or
     · Press standby to take manual control of the boat.

     Avoiding obstacles
     In Track mode you still have full control from the keypad. You can change course to
     avoid obstacles by manually steering away from the obstacle or by using the course
     change buttons (-1, +1, -10 or +10).
     When manually steering around an obstacle,the preferred method is to:
     1. Press standby, to return to Standby mode.
     2. Manually turn the wheel to steer away from the obstacle.
Chapter 2: Using Track mode                                                                             17


      3. Press auto to re-engage Auto mode.
      If you do not have time to engage Standby mode (e.g. in an emergency), manually
      turn the steering wheel to steer away from the obstacle, whist still in Track mode.
      When you have passed the obstacle, press standby then auto, to re-engage Auto on
      the previous locked heading.
      Once you are safely past the obstacle, either:
      · Return to your previous planned track, by pressing track then responding to the
         NEXT WPT message by pressing track again
      or
      ·     Use your chartplotter to initiate a new route to the waypoint.

      Track keeping & Cross Track Error
      Cross track error (XTE) is the distance of the vessel from the planned track. An XTE
      can be generated if:
      · You enter Track mode when positioned some distance from the planned route.
      · You make a manual course change to avoid an object.
      · You arrive at a waypoint (see page 20).
      CAUTION:
      When entering or returning to Track mode the heading will initially
      be BTW, but may change slightly as the autopilot removes the XTE,
      to achieve the defined track leg.

     Best practice track keeping demands that the vessel follows the predefined Track Leg
     as closely as possible. This is to avoid potential collision with charted objects that may
     be near the defined path
     The Raymarine Track keeping algorithm ensures safe operation by correcting any
     XTE as quickly as possible, but with a maximum convergence angle of 30º with the
     Track Leg. It then maintains the vessel tightly on the desired track.
     Large cross track error
     If a cross track error of greater than 0.3 nm occurs, the SPX-5R Drive system will
     sound a Large Cross Track Error warning and the Pilot Controller will show whether
     you are to the port (Pt) or starboard (Stb) of the planned track.

     Tidal stream compensation
     Under most conditions, the SPX-5R Drive system will hold the selected track to within
     ±0.05 nm (300 ft) or better. It takes account of the boat's speed when computing
     course changes to ensure optimum performance.

         WARNING: Ensure safe navigation
         Before changing course, always ensure it is safe to do so.
         Always be aware of the relative wind angle, especially when
         turning away from the wind.

      To steer to the next waypoint in the route
      When the Waypoint Advance warning sounds, the SPX-5R Drive system suspends
      Track mode and maintains the current boat heading.To advance to the next waypoint:
      1. Check that it is safe to turn onto the new track.
      2. Press the track button, to cancel the Waypoint Advance warning and steer the
         boat to the next track leg.
      Note: If you do not press track to accept the Waypoint Advance, the SPX-5R Drive system will
      maintain the current heading and continue to sound the warning.

      To skip a waypoint (SeaTalk chartplotters only)
      If you want to advance to the next waypoint before you have arrived at the current
      target waypoint, you can skip the current waypoint by pressing track for 1 second.
      The display will then show a Waypoint Advance screen for the next waypoint. Check
      it is safe to turn, then press track to turn the boat towards the next waypoint.

     Waypoint arrival circle
     As the next Waypoint warning occurs within a circle around the actual waypoint, the
     next waypoint will probably be accepted some distance from the planned track leg.
     This can result in a cross track error and associated course correction.

Chapter 3: Troubleshooting & Maintenance
   This chapter provides information to enable you to identify problems, interpret alarm
   messages, maintain your SPX-5R Drive system and obtain product support.
   Raymarine products are designed to provide many years of trouble-free operation.
   They are also put through comprehensive testing and quality assurance procedures
   before shipping.
   However, if a problem occurs with your SPX-5R Drive system, use the
   troubleshooting tables in this section to help identify the problem and provide a
   solution. If you cannot resolve the problem yourself, refer to the product support

3.2 Maintenance
      Important
      Before attempting any maintenance procedure on the SPX-5R Drive system, ensure
      the boat is securely moored alongside and that power to all system components is
      switched off.
      CAUTION: Avoid damage when cleaning
      Do NOT use solvent or abrasive cleaners on any SPX-5R Drive system
      components.

      Spare parts
      CAUTION: Do not dismantle SPX-5R Drive system products
      The SPX-5R Drive system does not contain any user serviceable
      parts other than those specified below, and so should be serviced
      only by authorized Raymarine service technicians.
      The only user-replacable components in the SPX-5R Drive system are the Course
      Computer fuses, and these are available from your Raymarine dealer:
      · Fuse F1 - 15 A (power in fuse). Part number 15454.
      · Fuse F2 - 2 A (SeaTalk fuse). Part number 15455.
      If any other parts require servicing or replacement, please contact your Raymarine

     EMC Servicing and maintenance
     ·   Undue noise and interference may be a symptom of an EMC related problem,
         Always report any EMC-related problem to your nearest Raymarine dealer. We
         use such information to improve our quality standards.
     ·   To minimize any EMC related problems and ensure the best possible
         performance from your Raymarine equipment, follow the guidelines given in the
         installation instructions.
     Suppression ferrites
     Raymarine cables may be fitted with suppression ferrites. These are important for
     correct EMC performance. Any ferrite removed for maintenance purposes must be
     replaced in the original position once the maintenance is complete.
     Use only ferrites of the correct type, supplied by Raymarine authorized dealers.

     Pilot Controller
     The Pilot Controller is a sealed unit, so user maintenance is limited to the following
     routine tasks:
     · Ensure all cable connectors are securely connected.
     · Examine the controller and cables for signs of wear or damage. Replace any
        damaged components.
     CAUTION: Avoid damage when cleaning
     Do NOT wipe the Pilot Controller display screen with a dry cloth as
     this could scratch the screen coating.
     Using a clean, damp cloth, wipe the Pilot Controller. Do NOT use chemical or abrasive
     materials to clean the controller.
     Note: In certain conditions, condensation may appear inside the display screen. This will not
     harm the unit, and you can clear it by switching on the illumination for a short time.

     Drive
     Routine maintenance
     Daily inspection before commencing any passage:
     - Visually inspect the Drive installation.
     - Check autopilot operation.


     Daily inspection after each passage:
     After each trip, wipe the drive unit clean with a damp cloth, to remove salt or other
     deposits.


     Annual inspection:
     Check once per year that the Drive, and associated torque restraint are securely fitted
     and have not worked loose during usage.
     Remove any deposits from the emergency release pin and check its operation.

      Service interval:
      Inspect and service in line with your steering system manufacturer
      recommendations.
      In any event a Raymarine approved service must be carried out every 2 years or 200
      engine hours, whichever occurs soonest.
