Simrad AP25 Marine Instruments User Manual


 
Configuration and setup
20221495F 133
If the hardware for automatic HI/LO selection is connected
and configured, verify that the HI/LO transition is occurring,
and the HI/LO parameters are changing after the transition
speed is crossed (by more than 1 Knot higher or lower speed).
Try the effect of LO and HI parameter settings.
Try the Dodge and U-turn function.
If a Non-Follow Up lever (or handheld remote) is connected,
test change of modes and verify port and starboard steering
commands of the lever.
Set waypoints into each navigator connected to the system,
and verify that the AP25 steers in NAV mode for each NAV
source.
Try the NoDrift mode.
If the boat is a sailboat use the WIND mode and try the AP25
at different settings of the apparent wind angle. Also try the
WINDN(av) mode, optimized VMG and WCV when sailing
(tacking) to a waypoint.
If the rudder response feels aggressive during the sea trial,
you may want to reduce the rudder speed to get a smoother
steering.
Alternatively on a sailboat you may want to have a higher
rudder speed when running. The motor Drive out (page
104)
can be set with this in mind. Never adjust in more than 10%
steps with respect to the reading set during the automatic
rudder test (page
103). Always perform a new Autotune after
the adjustment.
Provide the owner with user training.
Providing user training
The user should be instructed in the "basic" operational
functions, such as:
Turning the system on and off
Changing modes. Explain briefly what takes place in the
different modes.
Regaining manual control from any mode. Point out in what
modes the helm is engaged by the autopilot (bypass/clutch).
Taking command at an "inactive" station, if applicable.
