Display Function - Marine Autopilots, Engine Controls and Instruments

Tiller button (Autopilot
ON-OFF switch):
A separate pushbutton can be connected
to the Drivebox at the AUX-2 connector (on
older Driveboxes the button is connected to
the rudder sensor cable).
Briefly pressing this button disengages
the autopilot and the Fly-By-Wire Servo-
Wheel.
By holding the button for 3 seconds, the
autopilot engages in HDG mode, similar to the
application of the HDG button on the AP display,
or to the AP button of the Fly-By-Wire
Station.
Installation of the ON-OFF button at the
tiller tip is recommended for yachts with tiller
steering. Otherwise install this button within
easy reach of the manual helm.
Additional Autopilot
Functions for Yachts:
Wind Modes
The Wind Modes require a wind sensor and
a gyro in the system. A wind display is not needed.
The TRUE Wind Mode is the preferred mode
for stable steering. It requires boat speed data
or Ground Speed data available (with Ground
Speed substituting water speed, the calculated
relative true wind angle will become less accurate
with increasing set).
HDG
WIND
AP-OFF
NAV
Press the WIND-button
briefly: The left
WIND-LED comes on for
the apparent (A) autopilot
wind mode. Press
the button again and
the right WIND-LED
comes on for the true
(t) wind mode. The
present wind angle
(apparent or true) is
taken as target wind
angle. It can be altered
as needed with the left or
right arrow buttons.
Tacks and Jibes:
Pressing both arrow
buttons simultaneously will trigger a tack,
when the target wind angle was smaller than
90 degrees. A jibe will be started, if the target
wind angle was greater than 90 degrees.
Note: a tack or a jibe may be stopped any
time by briefly pressing the HDG-button (if the
Heading-Mode is available).
100-degrees tack
in Compass Mode:
This function is useful
on Sailing Yachts with no wind
instruments. Press and
hold HDG-button for
three seconds, until
the HDG-LED changes
from yellow into red.
HDG WIND NAV
The autopilot is now
AP-OFF
armed for tacking. A
100-degrees heading
change can be triggered
with the left or right
arrow button. The HDG-LED
starts blinking (yellow) until the new target heading
has been reached.
The heading change may be stopped any
time by briefly pressing the HDG-button. Actual
heading (or track) will then be followed.
Warnings:
Sensor Warning
Dashes on the
display are an indication
for the absence
HDG WIND NAV
of valid data from the
AP-OFF
required sensor.
Make sure that
the configuration of
the display corresponds
with the physically
connected sensor (verify correct values of
SE: and n0:).
Settings:
Illumination
If you have a dimmer installed in the system,
use only the dimmer. Otherwise use the push
buttons for illumination
control:
1. Press and hold all
three buttons.
2. Release
SELECT button first,
SELECT
then the others.
3. Adjust brightness
with left or right button.
All other displays with the
same group number will follow
in brightness.
Do not use buttons on an autopilot display
in Wind Mode! Either use other display
unit for illumination or select head-
!
ing or NAV mode, for example.
