Helpful hints during sea trial of the AP9 MK3
Rate of Turn (ROT)
If in doubt of optimal vessel ROT, and before setting the ROT
parameter, it may be helpful to enter the debug loop, and scroll
through the menu until the vessel current ROT is displayed.
At service speed, make a manual, at least 90° constant turn at the
desired rate, then read the calculated ROT from the display. This
value will be a good starting point for wanted operation and may be
tried as the ROT parameter setting.
Service speed and speed sensitivity
The service speed should be set to the vessel highest speed of normal
operation. If the vessel is used at all speeds, the service speed
parameter should be set to full speed, but if the vessel typically do
not exceed it's cruising speed, the parameter should be set to this
speed.
The speed sensitivity should be adjusted after the vessel is steering
satisfactory. E.g. when the rudder setting (P-factor) is adjusted to
desired value at service speed, reduce speed to a lower working
speed (for instance half the service speed), now set the speed
sensitivity parameter to a level where the vessel steers satisfactory at
the lower speed.
