INSTALLATION

DRIVE UNIT

The drive unil is mounled belween the

 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 

 installation two basic

dimensions are critical (Fig.l):-

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.

Deviation of

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

BASIC PRINCIPLES

 

lollowing 

   

 

2000’s principle of operalion will help you
lo make lull use   ils advanced lealures.

The powerful 

 of a 

compass and microprocessor 

provides ‘aulolock’ course selection

 wilh precise 

 course

adjuslmenl.

Deviation from course is continuously

monilored by a sensitive 

compass and 

 rudder is

applied lo relurn 

 vessel lo course.

The applied rudder is proporlional lo
course error al any lime and lhus when

 course is restored 

 rudder will be

neulralised.

When changes in vessel lrim occur

due lo varialions in wind pressure or

engine 

 selling 

 course can

only be rnainlained by 

 

 

permanenl rudder 

 (standing helm)

lo reslore balance. II permanenl rudder

that

 SYSTEM

Pcrlormance under windvano has been
improved by 

 

 of Wind

Trim.

Wilh Wind Trim the compuler uses 

 compass as the primary

heading 

 However, as changes

occur in the apparent wind angle the
compuler automatically adjusts 

compass heading lo maintain 

 original

apparent wind angle.

This 

 eliminates the ellecls

 autopilot is set lo either  Auto or

Vane  mode a built in off-course alarm is

 sel up. The off-course

alarm will sound when the vessel
deviales for any reason from 

 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 

  vessel does not return

within these limils the alarm can only be

silenced by selecting  Standby.

In  Vane, 

 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 

 off

course alarm datum to 

 current

compass heading.

CURRENT LIMITING AND

.

CUTOUT
If the autopilot is driven into its end stops,

 drive will be  pulsed  lo prevent

.

overloading 

 motor. If 

 

 is left in

this condition for 30 seconds the
microprocessor will 

 cut 

power to the motor and sound the alarm

continuously.

To restore 

 autopilot for normal

operation the  standby  key  must be

pressed lo put 

 unit in  standby

operating mode.

Rudder Control Adjustment
The rudder 

 setting

recommended on page 21 will provide
slable control for 

 sea trials.

However, sailing 

 can vary widely in

their response lo 

 helm and further

adjustment of 

 rudder control setting

may improve 

 Autohelms steering

characteristics.

An excessively high rudder control

selling results in  oversteer  which can be

recognised by 

 vessel swinging slowly

lrom side lo side of 

 

heading accompanied by excessive
rudder movemenl. In addition, 
overshool will  be observed when 
course is changed. This condition can be
corrected by reducing the rudder control
selling (rolaling rudder control 
clockwise).

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

 rudder control selling (rotating

rudder control clockwise). These

 are most easily recognised in

calm sea 

 where wave 

does not mask basic sleering

performance. The rudder control setting
is 

 over critical and should be sel lo

 lowest selling 

 with

accurate course keeping. This will
minimise actuator movements and hence
reduce power

OPERATING HINTS

 

The Aulohelm 2000’s computer
continuously optimises 

steering performance 

 the

need 

 operalor supervision.

II is, however, very 

 lo

undersland the effect of sudden trim
changes on steering performance. When

a sudden change in 

 occurs the

automatic trim compensation system

requires approximately 60 seconds to

apply the necessary rudder off-set to

restore 

 

 heading. In gusling

condilions, therefore, the course may

lend lo wander slightly. particularly in 
case   a sailing 

 with badly

balanced sails. 

 

 

 case, a

 improvement in course

keeping can always be obtained by
improving sail balance. Bear in mind 
following imporlanl 

Do not allow the yacht lo heel

excessively.

Ease lhe mainsheel 

 lo

leeward lo reduce heeling and
weather helm.

   necessary reef the mainsail a 

early.

II is also advisable whenever possible

lo avoid sailing with 

 wind dead astern

in very slrong winds and large seas.
Ideally, 

 wind should be brought al

least 

 away from a dead run and in

severe conditions il may be advisable to
remove the mainsail altogether and sail
under headsait only. Providing lhese
simple precautions are taken the

autopilot will be able to 

competent control in gale force
condilions.

It may be 

 

 

 autopitol

tends lo be a 

 

 slable on northerly

headings in the higher lalitudes of the

 hemisphere (and corivcrscly

soutt 

 headings in the southern

hemisphere). This is caused by the
increasing angle   dip of the 

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   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!

TOTE BAG

A special zip top padded bag made from
lough PVC is available lo 

 and

Do not slow your Aulohelm in a locker

liable to flooding by the bilge water.

 Do 

 leave your

locker over the winter lay up period.

MAINTENANCE

All moving 

 the system have been

lubricated for life at the 

 Therelore

 

 whatsoever will be

required. Should a 

 develop 

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 

 connections are light

and free from corrosion.

Since 

 control unit is lhe most

complex, there is a very high probability

that if a fault has occurred it is in this unit

which should therefore be returned for
repair, which wilt be carried out speedily

and al moderate cost. The drive unit has

  lo be extremely reliable and  is

very unlikely to develop a fault.   however
the drive unit is 

 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 

 case of a sailing yacht fitted with

 system if a fault occurs only

in vane mode then it is likely lhal a fault
has developed in the vane head.
