1.6.4 Speed coefficient
Principle of operation
: the
Gyropilot
computer automatically determines the speed
coefficient, and adjusts the angle of helm proportionally to the speed of the boat. The higher the
speed, the lower the angle of helm.
However, if this setting is not appropriate it is possible to amplify or to reduce the amplitude of
the angle of helm, by modifying the
speed coefficient
. It is adjustable between
1
and
53
. The
higher this value, the higher the angle of helm, proportional to the speed of the boat. By default,
the
speed coefficient
is set at
6
.
Please note that when the channel
surface speed
is not present on the bus, the
Gyropilot
uses the
speed over ground
channel (if it is present on the bus).
Useful tip
: to check the effectiveness of your setting, enter an extreme value, for example
50
, and compare the behaviour of your boat, before the setting and after this extreme setting. A
difference in the behaviour of the pilot should be observed with the two settings.
1.6.4.1 Degraded mode
If the channels
surface
speed
and
bottom speed
are not present
on the
TOPLINE
bus, then
the
Rudder coefficient
parameter assumes another meaning: it becomes the average speed of
the boat. This mode of operation is less efficient, but is used in case the measurement of speed
breaks down. In that case, disconnect your depth-log interface from the bus, and restart the
installation (the
speed
channel must no longer be present on the bus). Then, enter the average
speed of the boat in the
rudder coefficient
.
1.6.5 Rudder offset
This parameter allows you to set the middle point of the rudder, from -3° to +3 in relation to the
axis of the boat. By default, the
rudder offset
is set at
0
°.
1.6.6 Time before cut-off
This time lag is used to force the pilot to keep control of the rudder in case of a communication
breakdown with the
TOPLINE
bus. The time lag is adjustable between 6 and 60 seconds, and
the default value is 6 seconds.
