Note:
The setup of the compass should be done in calm sea
conditions and with minimal wind and current to obtain good
results. Ensure that there is enough open water around the
vessel to make a full turn.
Refer to your heading sensor's documentation for further details for
your unit.
Transition speed
Ú
Note:
Only available if the boat type is set to Planing.
The transition speed is the speed at which the system automatically
changes between
Low
speed and
High
speed profiles.
The profiles are used to accommodate the boats' tendency to
exhibit different steering characteristics at different speeds. You may
also have different preferences about the steering performance of
your boat required at low and high speeds.
It is recommended that you set a value that represents the speed
where the boat's steering characteristics change. For instance the
planing threshold (recommended), or at the speed you want the
autopilot to change behavior.
There is a 2 knots hysteresis to prevent oscillation of high/low
settings when the vessel is travelling at or near the transition speed.
Example
The transition speed is set to 9 knots.
•
The system changes from Low profile to High profile when the
speed increases to 10 knots (= Transition speed plus 1 knot)
