Aulohelm 2000 is an up.to-lhe-minule digital liller autopilot which shares Ihe same microprocessor Iechnology buill into our biggest and mosl sophisticaled lully inslalled pilols. II will provide precise powerful sleering lor sailing yachls up lo 13m (43') LOA. The basic system comprises Ihe main control unit, liller drive unil and basic mounting fillings. This can be exlended by adding any of Ihe following accessories: l l l Windvane Radio Navigation interlace Hand Held Conlrol Unit The lull syslem is shown below. INSTALLATION SLOPING RUDDERSTOCK DRIVE UNIT The drive unil is mounled belween the toiler and a single allachmenl poinl on the yacht's structure. After connection to the yacht's 12 volt electrical system the unit becomes operational. For correcl installation two basic dimensions are critical (Fig.l):Dimension A = 620mm (24.5") mounling socket lo tiller pin Dimenslon B = 460mm (16") rudder stock cenlre line to tiller pin Clamp Ihe tiller on the yacht's cenlre line and mark elf dimensions A and B (A is measured on the STARBOARD side of the cockpit) using masking tape to locate the fixing points. Ensure the measurements are at right angles as shown. The drive unit must be mounted horizontally. I PORTHAND MOUNTING In certain circumslances it may be more convenient to mount the unit on lhe porthand side. When this is the case, the changeover switch will require adjustment as lollows. Use a screwdriver to rotate lhe switch anli.clockwise until the endstop is reached (Fig. 2). Never force the changeover switch, light pressure only Is required.

The control unit should be siled where it can be operated easily horn Ihe steering positron. It should also be posilioned al leas1 60cm (2'6") away lrom lhe main steering compass lo avoid devialion of both compasses. Deviation of the control unit fluxgale compass is less imporlanl since headings are always adjusted by reference lo the main sleering compass. Nevertheless, deviation should be avoided if possible and thus the conlrol unit should be siled as far away from other magnelic or iron devices as praclical. Having selected the besl mounling site, the mounling sockel may be secured lo a convenient wooden or glass libre surface using the self lapping screws provided. The mounling surface may slope away from verlical by a maximum of 459 Accessory Connection In common wilh all Ihe Aulohelm 2000's accessories, the drive unit plugs inlo Ihe conlrol unit lo facilitate slowing and servicing. To ensure reliable connection each plug incorporates a locking ring which should be turned clockwise lo secure. Although each accessory has a unique socket and cannot be misconnected, Ihe drive unit should be connected lo Ihe sockel marked Helm, Ihe windvane to Ihe socket marked Vane and the hand held remole conlrol lo Ihe sockel marked Remote. OPERATION WINDVANE ATTACHMENT \ \ I I!, I .I BASIC PRINCIPLES TIE w~ndvane atlaclrrrrcnt is normally niounled cenlrally on lhe alter rail where it can be sited in clear wrnd on bolh lacks. The windvane mounting masl is clamped lo Ihe aller rail by Ihe Iwo `U' bolls provided (Fig.12). The inlerconnecling cable should be broughl Ihrough Ihe slol lo allow Ihe windvane head to be plugged into Ihe lop 01 Ihe masl (Fig.13). The inlerconnecling cable can lhen be run back and plugged inlo Ihe Aulohelm 2000. Note The windvane head is supplied with Ihe vane detached for ease of packing. The vane is easily assembled lo lhe head and secured by means 01 lhe circlip provided (Fig.14). Care should be laken lo ensure that the small circlip is correclly locqled inlo lhe groove. m lollowing descriplion 01 Ihe Aulohclrn 2000's principle of operalion will help you lo make lull use 01 ils advanced lealures. The powerful combirralion of a Iluxgale compass and microprocessor conlrol provides `aulolock' course selection logelher wilh precise push-bullon course adjuslmenl. Deviation from course is continuously monilored by a sensitive fluxgate compass and correclive rudder is applied lo relurn lhe vessel lo course. The applied rudder is proporlional lo course error al any lime and lhus when Ihe course is restored Ihe rudder will be neulralised. When changes in vessel lrim occur due lo varialions in wind pressure or engine Itirollle selling lhe course can only be rnainlained by Ihe applicalion 01 permanenl rudder oif-sel (standing helm) lo reslore balance. II permanenl rudder oll-sel is nol applied lo restore balance the vessel will bear on lo a new heading. Under lhese circumslances Ihe Arrlol~elm 2000 clclecls llial Itie origrnal course is nol berng reslored and conlinues lo apply addrlional rudder ollscl in llie appropriale direclion urilil the vessel relurns lo Ihe origirral treading. Aulomalic lrimming capability ensures that Ihe originally sel course is held irrespective of any changes in balance Ihal may occur during Ihe course 01 a passage. The Aulohelm 2000's computer also continuously monilors Ihe pallern of applied rudder correclion and can distinguish unnecessary repetilive corrections caused by prlch and roll of Ihe vessel lrom those necessary IO rnainlain Ihe selecled heading. The computer will automatically , neglecl all unnecessary correclions so Ihal aulopilol aclivily and power consumplion is conlrnuously oplimised al minimum levels. The high degree of control aulomalion made possible by the micro compuler simplilies user control lo a series 01 push bulton operations. 14 KEYPAD OPERATION Full conlrol of Ihe Autohelm 2000 is provided via a simple six bullon key pad. The basic control functions are as tallows:- ii When the aulopilol is swilched on il wilt always star1 up in Stand by mode. In Stand by mode Ihe pushrod can be exlended or relracled lo engage wilh Ihe tiller pin using the four black bullons. ii Push and hold down lo exlendlrelracl Ihe pushrod. t, 0l .u 0 AUTO Push once lo engage the aulopilot lo mainlain Ihe currenl heading or push twice (wilhin 2 seconds) lo return lo Ihe previous aulomalic heading. 66 -10 4-10 Push lo aller course lo port (-) or slarboard (+) in incremenls of 1 and 10 degrees. STAN Push once lo disengage Ihe autopilot and relurn to Stand by mode. (The previous automatic heading will be memorised). -- __. _ _ _ _ _ WINDVANE SYSTEM Pcrlormance under windvano has been improved by Ihe inlroduction of Wind Trim. Wilh Wind Trim the compuler uses Ihe fluxgate compass as the primary heading relerence. However, as changes occur in the apparent wind angle the compuler automatically adjusts Ihe compass heading lo maintain Ihe original apparent wind angle. This syslcm eliminates the ellecls 01 turbulence or shorl term wind varialions and provides smooth precise perlormance under windvane with minrmum current consumption. When a wrndvane syslem is lilled. a new layer 01 control funclions is aulomatically opened as follows:- AUTOTACK FUNCTION The Aulohelm 2000 has an automalic lacking lunction which operales in both compass and windvane mode as lollows:- Push both red keys togelher once to engage the windvane and mainlain Ihe currenl apparent wind angle. or Push both red keys logelher twice to return lo Ihe previous apparenl wind angle. __--- - Push once to alter the vessel's heading relative lo the apparent wind in increments of 1 or 10 degrees. Note + keys always turn the vessel to starboard. 0 +1 , Push -1 and -10 keys logelher once to iniliale a tack to port. -10 +10 Push +l and +lO keys togelher once lo initiale a lack to starboard. a 0 STAND BY Push once lo disengage Ihe windvane for manual sleering. (The previous apparent wind angle wilt be memorised). or Push once to change over to , aulomalic compass heading control and maintain Ihe current heading. The Aulo Tack function operales by selecting a preset course change (100") to bring Ihe vessel onlo the opposite tack. During the tack, the Of1 Course Alarm may sound. This indicates the autopilot is adjusting trim to acquire the new course. On completing the tack and having sheeted and retrimmed the sails, the vessel rnay be brought onlo Ihe desired apparenl wind angle by line adjuslmenls lo lhe course using the t/-lo keys. No adjustments should be made within 1 minule of compleling the tack to allow the Autopilot to compensate lor the helm trim on the new tack. 0 AUTO 0 I 19 OPERATING MODE INDICATION The operating mode of Ihe Aulohelm 2000 is indicated by a flashing LED as follows:- FUNCTIONAL TEST PROCEDURE Afler compleling (he ins(allalion you should carry out the following lunclional lesl lo familiarise yourself wilh Ihe syslem before allempting sea Irials. Plug Ihe Aulohelm 2000 inlo Ihe power sockel and switch on Ihe eleclrical supply. The unit will emit a short beep Lone lo indicale lhat it is aclive and (he LED will flash to indicate Stand by operaling mode. Ensure the mounting pin is engaged in the socket. Using Ihe four course control keys to extend or relracl Ihe pushrod posilion the end over Ihe tiller pin. The unit will emil a short beep lone on each press of a key lo confirm valid enlries. Place Ihe pushrod end on Ihe liller pin, and press Ihe +lO key. The liller should move lo porl. II the litter moves to slarboard, the changeover switch is incorredy set and musl be adjusted as described on page 3. Press Auto lo place the aulopitot under compass control. The LED will be tit constantly to indicale that Ihe unit is in Auto mode. If Ihe yacht is swinging aboul ils mooring, you will see lhat small variations in heading cause the unii to apply correclive action lo the rudder. Press Stand by lo relurn Ihe unit lo Stand by mode. Rudder Control Adjustment Before allempling sea lrials Ihe rudder ' conlrol musl lirsl be adjusled lo Ihe selling shown below. OPERATING MODE STANDBY Enables Ihe pushrod lo be positioned over the tiller pin and provides power sleenng. AUTO Autopilot steers to maintain compass heading. WINDVANE Aulopilol sleers lo maintain apparent wind angle. Windvane mode is also confirmed by a single beep tone emitled every 30 seconds. LED FLASIHING CODE 1 I I This selling will provide stable control for inilial sea trials and may, if necessary, be fine luned later (see page 25). - -mliow Hand Held Control Unit (Cat No. 2076) An optional hand held conlrol unit can be plugged inlo Ihe control unil to provide full course change capability from anywhere on board. The unil duplicates the main control units four course change keys and may be used in bolh Stand by and Auto modes. The operalion of the main conlrol unil is unchanged when Ihe hand held conlrof unit is connecled. Radio Navigation Interface (Cal No 2075 .- MMEA lormal) `IIll:; llllOllilCX! lll;ly IX?

The previously conducled functional lesl will have verified lhal Ihe aulopilol is operaling correclly and lhal you are familiar with all of its conlrols. During lrrst sea trials. Ihe vessel will be conslanlly changing heading, and il is, Iherelore. very imporlanl lo mainlain a constant look.oul. The following initial lrial procedure is recommended:@ Steer on to Ihe desired heading and hold the course steady. l Using the lour course control keys, position and lhen place Ihe pushrod end over Ihe lillcr pin. l ' . Aller course lo porl or slarboard in rnulllple incrcmenls of 1 and 10 degrees. Power Steering l Press Stand by and praclice power steering using the four course conlrol keys. l Press Auto lwice (wilhin 2 seconds) lo return to Ihe original automatic heading. Hand Steering l Press Stand by and Ml the autopilol lrom the tiller pin lor return to hand sleering. Automatic Sea State Control During the sea Irial. the operation 01 the automatic sea stale conlrol can be observed. When the aulopilol is initially engaged in Auto mode the aulopilot will respond lo all pilch and roll movemenls. During the lirsl minule of operation, it will be noticed lhat repetitive movements of the vessel are gradually neglected until linally the aulopilot will respond only lo true varialions in course. To ensure accurale course adjustment the sea stale control is automatically reset whenever a 10 degree course change is executed. Sea State tnhibit Where maxmum course keeping accuracy is required the automatic sea stale control may be inhibited by pressing -1 and +l keys together once Autopilot aclivity and lherelore power consumption will be increased but , course keeping accuracy will be maximised. The automatic seaslale control is reslored by pressing the -1 and +l keys together. Note Engaging the autopilot (pushing Auto) or engaging the windvane (both red keys logelher) will always reslore the automalic sea state conlrol. 0 Press Auto lo lock on lo Ihe currenl heading. In calm sea conditions a perfectly constant heading will be maintained. i 22 _.--..--.~ - - - -l Auto-Tack Function The following addilional trial is recommended: Steer onto a constant heading approximately loo free of close hauled Press Auto to lock onto the current heading or bolh red keys lo lock OnlO Ihe apparenl wind if a vane is filled. v v 1 . The yacht will complele a 100° course change IO bring it onto Ihe opposite lack. WINI) * Disengagement The pushrod is held inlo engagement wilh the lilter pin by Ihe weigh1 of the aclualor unit. This melhod of engagement is secure and has been adopted for safely reasons lo allow Ihe pushrod lo be easily disengaged when manual override becomes necessary. OFF-COURSE ALARM When the autopilot is set lo either Auto or Vane mode a built in off-course alarm is aulomatically sel up. The off-course alarm will sound when the vessel deviales for any reason from the original course by more than 15 degrees for over 10 seconds. II is denoled by a continuous series of bleep lones. The alarm will be silenced if the vessel returns to within 15 degrees of the original course. In Auto, if the vessel does not return within these limils the alarm can only be silenced by selecting Standby. In Vane, the alarm will sound when the wind direction changes by more lhan 15 degrees and may be accepted by pressing bolh red keys together. This will silence the alarm and advance Ihe off course alarm datum to the current compass heading. . CURRENT LIMITING AND CUTOUT If the autopilot is driven into its end stops, Ihe drive will be pulsed lo prevent overloading Ihe motor. If the pilol is left in this condition for 30 seconds the microprocessor will aulomalically cut out power to the motor and sound the alarm continuously. To restore the autopilot for normal operation the standby key must be pressed lo put Ihe unit in standby operating mode. w l Decrease the apparenl wind angle (using the +l key if on the slarboard lack) unlil the yachi is sailing close hauled al oplimum penetration. On compleling lhe lack and having sheeted and retrimmed Ihe sails, the vessel may be brought onlo the desired apparent wind angle by fine adjuslmenls lo Ihe course using Ihe +ll-lo keys. No adjuslmenls should be made within 1 minute of compleling the lack lo allow the Autopilot lo compensale for the helm trim on Ihe new lack. l Prepare to lack and then press Ihe + 1 and +lO keys together (if on the starboard lack) to initiate a lack IO slarboard. Rudder Control Adjustment The rudder conlrol setting recommended on page 21 will provide slable control for inilial sea trials. However, sailing crafl can vary widely in their response lo the helm and further adjustment of Ihe rudder control setting may improve Ihe Autohelms steering characteristics. An excessively high rudder control selling results in oversteer which can be recognised by Ihe vessel swinging slowly lrom side lo side of Ihe aulomalic heading accompanied by excessive rudder movemenl. In addition, distincl overshool will be observed when Ihe course is changed. This condition can be corrected by reducing the rudder control selling (rolaling rudder control anticlockwise). Similarly, an insufficient rudder control selling results in understeer which gives sluggish sleering performance and is particularly apparent when changing course. This is corrected by increasing Ihe rudder control selling (rotating rudder control clockwise). These lendencies are most easily recognised in calm sea condilions where wave aclion does not mask basic sleering performance. The rudder control setting is nol over critical and should be sel lo Ihe lowest selling consislenl with accurate course keeping. This will minimise actuator movements and hence reduce power consumplion. . it 25 OPERATING HINTS - -~--_._--______---___------The Aulohelm 2000's computer continuously optimises automalic steering performance etiminaling the need lor operalor supervision. II is, however, very imporlanl lo undersland the effect of sudden trim changes on steering performance. When a sudden change in lrim occurs the automatic trim compensation system requires approximately 60 seconds to apply the necessary rudder off-set to restore the aulomalic heading. In gusling condilions, therefore, the course may lend lo wander slightly. particularly in Ihe case 01 a sailing yachl with badly balanced sails. In Ihe laller case, a signiticant improvement in course keeping can always be obtained by improving sail balance. Bear in mind the following imporlanl poinls:l . -_-~_ MAINTENANCE All moving parIs. the system have been lubricated for life at the faclory. Therelore ii0 mainlenance whatsoever will be required. Should a lault develop Ihe autopilot's plugabilily ensures that only the defective unit need be returned. Before lhis is done please double check that the power supply cable is sound and that alt connections are light and free from corrosion. Since Ihe control unit is lhe most complex, there is a very high probability that if a fault has occurred it is in this unit -.----z.-p- Do not allow the yacht lo heel excessively. l Ease lhe mainsheel travetler lo leeward lo reduce heeling and weather helm. 0 It necessary reef the mainsail a tillle early. It may be noliced Ihat ltre autopitol tends lo be a litlle less slable on northerly headings in the higher lalitudes of the r~orllrerr~ hemisphere (and corivcrscly soutt rerly headings in the southern hemisphere). This is caused by the increasing angle of dip of the earlh's magnetic field at higher latitudes which has the effect of amplifying rudder response on northerly headings. The tendency towards norlherty heading instability is usually more obvious al higher speeds and when it occurs can be corrected by reducing the rudder control selling. Passage making under automatic pilot is a very pleasant experience which can lead lo the temptation of relaxing permanent watch. This must always be avoided no malter how clear the sea may appear to be. Remember, a large ship can travel Iwo miles in five minutes -just the lime it takes lo make a cup of coffee! which should therefore be returned for repair, which wilt be carried out speedily and al moderate cost. The drive unit has p10va11 lo be extremely reliable and is very unlikely to develop a fault. If however the drive unit is suspecled of being faulty it may be checked by connecting 12V across the sockets al the end of the drive unit cable and ensuring the motor runs normally. In Ihe case of a sailing yacht fitted with a windvane system if a fault occurs only in vane mode then it is likely lhal a fault has developed in the vane head. b.
