Port option
(depth decreases to port)
Starboard option
(depth decreases to starboard)
The following parameters are available for depth contour tracking:
Depth gain
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 NSO evo3 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 NSO evo3 control in standby mode if no rudder command is given
from the EVC system within a predefined period.
Using the NSO evo3 in an AP70/AP80 system
If your MFD is connected to an AP70/AP80 autopilot system, the MFD can be used to operate
the autopilot.
In an AP70/AP80 autopilot system, only one control unit can be active at the same time.
Ú
Note: The MFD cannot be used to configure or commission an AP70/AP80 system.
The thruster symbol on the Autopilot controller indicates thrusters are defined in
the AP70/AP80 autopilot system.
For more information about AP70/AP80 autopilot system, refer to the separate AP70/AP80
documentation.
Autopilot detection
The AP70/AP80 system has its own source groups. If the MFD is going to be used to run the
AP70/AP80 system, the MFD must use the same source groups as the AP70/AP80 system.
When a MFD is connected to an AP70/AP80 system, it detects the AP70/AP80 system and a
prompt is displayed asking if the MFD should restart and use the AP70/AP80 system source
groups (restart in professional autopilot compatibility mode).
