To set the hard-over to hard-over Rudder
Travel, press the
ADJUST
key twice.
This is used to more accurately calibrate
the digital rudder angle reading and does
not affect how far the rudder moves.
Press either the up or down
ARROW
key
until the number on the display equals
the actual number of degrees of rudder
travel.
Rudder Travel can be measured using
an analog Rudder Angle Indicator (if one
is fitted), or by measuring the stroke of
the hydraulic cylinder (Cylinder Stroke)
and the distance from the center of the
rudder post to the point on the tiller
where the cylinder attaches (Tiller Arm
Length). Then calculate the hard-over to
hard-over Rudder Travel using the
following formula.
Rudder Travel = 2 x Inverse Sine (Cylinder Stroke / (2 x Tiller Arm Length))
PILOT
The third operating mode is
PILOT
. The
autopilot will begin steering the vessel on
the last course it was on, just prior to
switching to
PILOT
, when you turn the
master select switch to this position. The
autopilot will use the last rudder angle on
the vessel as the first approximation of
dead ahead rudder.
This means that if you are towing a net
and require 15 degrees of port rudder to
make the vessel steer straight, the
autopilot will hold that rudder angle when
you turn to
PILOT
.
If the rudder angle is not correct, the
automatic trim function of the autopilot
will find the correct dead-ahead rudder
angle in approximately one minute.
