Wind shift
WINDSHIFT
This alarm is activated when a change in the apparent wind angle of
more than 15° is detected (see Section 3.2, Operation in Vane Mode).
Large cross track error
LARGE XTE
This alarm is activated when the cross track error exceeds 0.3 nm (see
Section 3.1, Operation in Track Mode).
The alarm is cleared if the heading recovers or the course is changed, or
if the operating mode is changed.
Drive stopped
DRIVESTOP
This alarm is activated if:
• the rudder reference transducer fails.
• the autopilot is unable to turn the rudder. This occurs if the weather
load on helm is too high, or if the rudder position is past the preset
rudder limits or the rudder end-stops.
Data not received
NO DATA
This alarm is displayed in the following circumstances:
• Compass not connected
• Track mode is engaged and the vessel arrives at the last waypoint in
the track
• Track mode is engaged and the autopilot is not receiving SeaTalk
navigation data.
• Track mode is engaged and the position transducer (GPS, Loran,
Decca) is receiving a low strength signal – this will clear as soon as
the signal strength improves.
• Vane mode is engaged and the autopilot has not received wind angle
data for 30 seconds.
The autopilot stops adjusting the heading as soon as data is lost.
