Controlling steering performance in automatic modes
The autopilot should be configured during installation and setup. Some parameters may
be adjusted during operation to increase the steering performance. Refer to "Autopilot
settings panel" on page 44.
Using the autopilot in standby mode
The autopilot must be in STBY mode when you steer the boat
manually.
You can switch the autopilot to STBY mode from any operation by a
short press on the OP40 STBY/AUTO key.
Power steering (NFU)
If you tap the PORT or STBD key icons in the pop-up dialog when
the autopilot is in STBY mode, the system will switch to NFU (Non-
Follow-Up). You can then use the key icons to control the rudder,
and the rudder will move as long as the key is pressed.
You return to STBY mode by a short press on the OP40 STBY/
AUTO key.
Follow-up steering (FU)
You can select Follow-up steering from the Autopilot menu.
When FU is active you can use the rotary knob to set rudder angle.
The set angle is indicated by the yellow pointer above the rudder
angle graphic. The rudder will move to the commanded angle and
then stop.
Warning:
While in Follow-up mode you cannot take manual control of the wheel.
You return to STBY mode by a short press on the OP40
AUTO mode (auto compass)
When the AUTO key is pressed, the autopilot selects the current
boat heading as the set course. The yellow arrow shows the
vessel's actual heading. If the arrow is pointing directly upwards,
the vessel is on course.
The autopilot will keep the boat on the set course until a new
mode is selected or a new course is set with the OP40 rotary knob
or the PORT or STBD key icons.
Once the course is changed to a new set course, the boat will automatically turn to the
new heading and maintain the new course.
Heading capture
When in AUTO or NoDrift mode the heading capture feature allows you to automatically
cancel the turn you are in by an instant press on the OP40 rotary knob. The autopilot will
cancel the turn to continue on the heading read from the compass the very moment you
pressed the OP40 rotary knob. This is a useful feature if you are not sure of the exact turn
you have to make to steer towards e.g. an inlet or a dock.
Turn pattern steering (power boats)
The autopilot includes a number of automatic turn steering features for power boats
when the pilot is in AUTO mode.
The turn steering option will not be available if the boat type is set to sailboat - instead
the tack/gybe feature is implemented.
