ST600R Autopilot Control Unit
After gaining experience with the ST600R, you may wish to change
the setting. The effect of the setting must be evaluated while under
sail.
• Decrease the AutoTrim level if the autopilot gives unstable course
keeping or excessive drive activity with a change in the heel angle.
• Increase the AutoTrim level if the autopilot reacts slowly to a
heading change due to a change in the heel angle.
• For systems without a rudder reference unit, these settings have no
effect and trim is set to level 3.
Power Steer
Power steer selects the Joystick mode of operation: Proportional or
‘Bang-Bang’.
Proportional applies rudder in proportion to Joystick movement –
the further the Joystick is held over the greater the applied rudder.
Bang-Bang applies continuous 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 centre position the rudder
will remain in its current position.
The settings available are as follows:
Range:
1 = Proportional
2 = Bang-bang
Default:
1
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:
1
