70 RayPilot 650 Control Unit - Owner’s Handbook
6 Adjusting Autopilot Settings
Rudder damping (rUd dPG)
Set this option during the initial dockside checks if the autopilot
‘hunts’ when trying to position the rudder.
Magnetic variation (vAr)
If required, set this value to the level of magnetic variation present at
your boat’s current position – indicated as east or west. The autopilot
sends this variation setting to other instruments on the SeaTalk
system, and it can be updated by other SeaTalk instruments.
AutoAdapt (AUt AdP)
The AutoAdapt feature allows the autopilot to compensate for
heading errors at higher latitudes, which are caused by the increasing
dip of the earth’s magnetic field.
The increased dip has the effect of amplifying rudder response on
northerly headings in the northern hemisphere, and on southerly
headings in the southern hemisphere.
Note: If you set AutoAdapt to
1 or 2, you then need to enter your
current latitude in the next screen (Latitude), so that the autopilot can
provide accurate course keeping by automatically adjusting the
rudder gain depending on the heading.
Latitude (LAt)
The RayPilot 650 only displays this screen if you have set AutoAdapt
to
1 or 2. Use the ▲ (NAV) and ▼ (LIGHTS) keys or course change
