This parameter determines the ratio between commanded rudder
and the deviation from the selected depth contour. The higher
depth gain value the more rudder is applied.
If the value is too small, it takes a long time to compensate for
drifting off the set depth contour, and the autopilot fails to keep the
boat on the selected depth.
If the value is set too high, the overshoot increases and the steering
is unstable.
Contour Cross Angle (CCA)
The CCA is an angle that is added to or subtracted from the set
course.
With this parameter you can make the boat yaw around the
reference depth with lazy-s movements.
The larger the CCA, the bigger yawing is allowed. If you the CCA set
to zero there are no lazy-s movements.
Using the autopilot in an EVC system
When the GO XSE is connected to an EVC system via the SG05, you
can take manual control of the steering regardless of the autopilot
mode.
The mode indicator on the Autopilot controller is replaced by a
dash to indicate EVC override.
The system returns to GO XSE control in standby mode if no rudder
command is given from the EVC system within a predefined period.
Autopilot settings
The autopilot settings can be split between settings done by the
user, and settings done during installation and commissioning of
the autopilot system.
•
User settings can be changed for various operational conditions
or user preferences
• Installation settings are defined during commissioning of the
autopilot system. No changes should later be done to these
settings
Both user settings and installation settings depends on which
autopilot computer that is connected to the system.
