BASIC PRINCIPLES
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

scl 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

al minimum levels.
