AC12N/AC42N Autopilot computer
Response (AC12N/AC42N)
The AC12N/42N includes three different sets of steering modes;
High (HI), Low (LO) and Wind. The mode can be automatically or
manually selected.
The speed at which the autopilot automatically changes from LO to
HI parameters (or opposite) is determined by the Transition speed
setting, defined during the commissioning of the autopilot. Refer to
the detailed description in the autopilot computer's
documentation.
You can manually fine tune each of the three response modes.
Level 4 is default with parameter values as set by the autotune
function. If no autotune is made (not recommended) the level 4
values are the factory default values.
• A low response level reduces the rudder activity and provides a
more “loose” steering
• A high response level increases the rudder activity and provides a
more “tight” steering. A too high response level causes the boat
to start lazy-s movements.
The Wind response is used on sailboats
• Increase the Wind value if the difference between the set wind
angle and the actual wind angle is too big
• Decrease the Wind value if the actual wind angle is S-ing around
the set wind angle, or if the rudder activity is too high
The performance mode is indicated in the top left corner of the
autopilot page.
• HI-A: High response mode set automatically
