The automatic tuning process is also verifying/adjusting
the “Rudder zero” alignment made in Dockside setup.
Automatic tuning is a procedure that is not required for the
AP24 to function as it is preset with steering parameters
that should steer most boats in the 30 - 50 foot range.
Recommended speed during Automatic tuning
should not
exceed 10 knots. It should be performed in calm or
moderate sea conditions, preferably when steering East
or West.
For displacement boats use a speed that is approximately
half the normal cruising speed (i.e. if cruising speed is 10
knots, perform the Autotune at about 5 knots).
The parameter values calculated during Autotune
becomes the HI parameters. The LO parameters are
automatically set to 66% of the HI.
After the Autotune has been completed the rudder must
be controlled manually, as the autopilot has returned to
STBY mode.
The Automatic tuning function will take control of the
boat and perform a number of S-turns. It must always be
performed in open waters at a safe distance from other
traffic. The Automatic tuning function may take from 2
to
3 minutes to complete. To stop the Autotune, press the
STBY key.
Activate the Autotune by pressing the
softkey.
After an Autotune, there should be no need for further
adjustments. Fine tuning of these parameters are made
by the response control (see page 14). However, viewing
or changi
ng the parameters can be made in AUTO mode
by entering ‘Installation’ in the Main menu. See also
“Recall Autotuned” below.
