Full delails are included. In case 01 any dillicully please conlacl our Technical Sales Deparlmenl lor assislance. The syslem is designed lor owner inslallalion which aided by Ihe lollowing guide should prove lo be a simple and inleresling job. After filling the equipment it is only necessary lo make a single adjustment lo the control unit lo match the aulopilols response lo Ihe sleenng characlerislics 01 your vessel. hood Sailing! 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. (/ 2 BASIC INSTALLATION Alter eslahlrshrng Ihe conlrol dimensions the Aulohelm 2000 can usually be mounled drreclly onto the Starboard cockprl seal (Fig 3). Proceed as lollows. TILLER PIN (Cal No. 0001) l Drill 6mm (l/4") hole x 25mm (1") deep al porn1 marked. l Using a Iwo parl epoxy adhesive such as Araldile, bond the tiller pin into place. l Position Ihe shoulder 01 Ihe pin 125mm (r/z") above Ihe liller surlace. MOUNTING SOCKET (Ca! No. D602) 0 Drill 12.5nlrn (l/2") hole x 25rnrn (1") deep inlo Ihe starboard cockpil seal. II Ihe slruclure thickness al Ihe mounling posilion is less Ihan 25mm (1") carelully reinforce Ihe under surface wilh a plywood plale bonded into position. lnslall the mounling sockel using Iwo par1 epoxy adhesive. Note The aulopilol is capable 01 generating high pushrod loads. Ensure lhal:l The epoxy is allowed to harden Ihoroughly before applying any loads; l Ail holes are drilled to correcl size and where necessary reinlorcing is provrded. INSTALLATION ACCESSORIES II il is not possible lo inslall Ihe drive unil directly onto Ihe cockpil seal or tiller as described, one 01 the lollowing accessories (or combinalion) will ensure a perfect inslallalion.

The Dri-Plug sockel musl be connecled directly lo the vessels electrical dislribulion panel and on no account paralleled into exisling wiring for other equipment. The Aulohelm supply must be independently switched and protecled by a 5 amp fuse or current trip. Since the autopilot is microprocessor based il is very imporlant lhat vollage losses in supply cables are minimised. Supply cables sl~oulcl Iherelore he as shorl as possible and 01 no less size Win sl~own in Ihe lollowirg lable. The brown wire of the Autohelm 2000 lead should be connecled lo positive.

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 r ...
