hardover time
To finish the rudder end stop calibration procedure
the autopilot must calculate the rudder hardover port
to hardover starboard time.
The following points must observed before carrying
out the procedure:
x If the boat is equipped with hydraulic power
assisted steering the engines must be running
when setting the rudder end stops and
measuring the hardover time.
x Move rudder to midships position.
x Highlight the ‘START’ command.
x Keep clear of the wheel.
x Press the ENTER key to start test.
The rudder hardover to hardover time can only be
calculated with the boat stationary.
If during the hardover timing, the rudder does not
move, check:
x The boat speed is less than 3 knots.
x The rudder reference unit must move through an
angle of at least 90
0 when the wheel is turned
from hardover to hardover.
x The output variation from the rudder reference
unit is greater than 1V from hardover port to
hardover starboard.
x Refer to the installation section for the rudder
reference unit and check the installation.
x The separate power supply to the ACP control
unit is switched on.
waterline length
Boat waterline length must be entered into the
autopilot for it to steer accurately. This value can be
entered in metres or feet.
