44 ST6000 Plus Autopilot Control Unit Owner,s Handbook
Proportional applies rudder in proportion to Joystick movement - the
further the Joystick is held over the greater the applied rudder.
Bang-Bang applies continous rudder drive in the direction of lever
movement. To improve control the speed of rudder movement changes
with the angle of the lever. For maximum speed push the lever
hardover. If the lever is returned to the center position the rudder will
remain in its current position.
The settings available are as follows:
Range: 0 = Off
1 = Proportional
2 = Bang-bang
Default: Off
Drive type
The drive type controls the way which the autopilot drives the steering
system. The default setting should be retained for mechanically driven
vessels.
Range: 1 = Mechanically driven vessels without a rudder reference unit
2 = Hydraulic, no rudder reference unit
3 = Linear, rotary and sterndrive with a rudder reference unit
4 = Hydraulic with rudder reference unit
Default: Displacement 3, semi displacement 4, planing and
4 sterndrive 3
Rudder damping
Set this option only if your system includes a rudder reference unit, and
the drive hunts when trying to position the rudder.
Test for this when your vessel is moored dockside, by pressing auto
and then +10. If the helm overshoots and has to drive back, or starts to
hunt back and forth, increase the damping level.
Alternatively, you can set a value between1 to 9. Adjust the damping
one level at a time, and always use the lowest acceptable value.
