Autopilot Settings - Simrad NSS9 Evo3S Operator's Manual

It is recommended to turn on the AP Depth Data Missing alarm when using DCT. When
this alarm is activated an alarm will be raised if the depth data is lost during DCT.
To initiate a DCT turn
• Steer the boat to the depth you want to track, and in the direction of the depth contour
• Activate auto mode, then select depth contour tracking while monitoring the depth
reading
• Select the port or starboard button to initiate the depth contour steering to follow the
bottom sloping to starboard or to port
Port option
(depth decreases to port)
Turn variables
• Ref. depth: this is the reference depth for the DCT function. When DCT is initiated the
autopilot reads the current depth and set this as the reference depth. The reference depth
can be changed when the function is running
• 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 will take a long time to compensate for drifting off the
set depth contour, and the autopilot will fail to keep the boat on the selected depth. If the
value is set too high the overshoot will increase and the steering will be unstable.
• 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 s movements.
The larger the CCA the bigger yawing will be allowed. If the CCA is set to zero there is no
S-ing.

Autopilot settings

The Autopilot settings dialog depends on which autopilot computer that is connected to the
system. If more than one autopilot is connected, the Autopilot settings dialog shows option
for the active autopilot.
Chart compass
Select to display a compass symbol around your boat on the chart panel. The compass
symbol is off when the cursor is active on the panel.
Select active autopilot
Selects if the autopilot controls the trolling motor or the outboard motor(s).
Autopilot data sources
Provides automatic and manual data source selection for the outboard autopilot.
Auto hide autopilot bar
Controls whether the autopilot information bar is shown when the autopilot is in standby.
