Factory default settings and automatic calibration, establish a basis for normal steering
and may be further fine tuned if necessary. During set up routines, the compass is
automatically compensated and installation errors such as reversed rudder feedback
and reversed pumpset wiring or piping are automatically diagnosed and corrected.
During this routine also the rudder speed is automatically optimised. This greatly
reduces installation set up and sea trials time while eliminating possible Autopilot
malfunction.
1.3 Components
1.3.1 Autopilot instrument
Control and display of all Autopilot functions are provided by the Autopilot instrument. It
is waterproof and may be mounted below or above deck. Multiple Autopilot instruments
can be connected and the Autopilot may be activated by pressing the push-buttons of
any instrument.
1.3.2 Course Processor R-1600
The Course Processor contains the course computer and pumpset motor drive circuitry
and acts as a centre for interconnecting wiring. It is splash proof and should be located
centrally to minimise lengths of wiring. The powerful microprocessor in the Course
Processor accepts heading information direct from an electronic compass or NMEA
compass wind transducer, navigators and compares this against the course set by the
instrument and rudder.
1.3.3 Rudder Angle Transmitter
The Rudder Angle Transmitter provides the Autopilot with accurate rudder position
information. It is mounted near the rudder shaft and connected to the tiller arm or
quadrant with an adjustable ball joint linkage.
1.1.1 Compass transducer
No Autopilot can steer better than the compass stability will allow. The Nexus compass
excels in this characteristic, where the liquid dampening provides for stability even at
high speeds in heavy seas. The high gimbaling angle, eliminates compass disturbance
with boat heeling or rolling. The compass provides a stable heading reference for the
Autopilot and should be bulkhead mounted below deck near the centre of pitch and roll
for maximum stability. Construction is splash proof. The Autopilot Course Processor or
the Nexus Server can re-transmit the compass heading on the NMEA output port to
receivers such as radars, plotters, compass repeaters etc.
1.1.2 Pumpset
Various sizes and types of pumpsets can be mounted into a hydraulic steering system.
The pumpset only operates when carrying out a rudder command. When the boat is on
course, the pumpset motor stops. A variable speed motor drive adjusts optimal rudder
speed and provides for minimum power consumption and maximising of rudder
positioning accuracy.
