ST600R Autopilot Control Unit
Drive Stopped
This alarm is activated if the autopilot is unable to turn the rudder.
This occurs if the weather load on helm is too high, or if the
requested rudder position is past the preset rudder limits or the
rudder end-stops.
Data Not Received
This alarm is displayed in the following circumstances:
• 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 locked heading as soon as data is
lost.
Waypoint Advance
The waypoint advance alarm sounds whenever the target waypoint
number changes, which occurs in the following circumstances:
• Automatic acquisition is selected by pressing
TRACK
from Auto
mode
• Waypoint advance is requested by pressing
TRACK
for 1 second in
Track mode (SeaTalk Navigators only).
When the alarm sounds, the pilot continues on its current heading,
but displays the bearing to the next waypoint and the direction in
which the boat will turn to take up that bearing.
Check that it is safe to turn onto the new track, and press
TRACK
to
accept the waypoint advance.
To cancel the alarm without accepting the waypoint advance, press
STANDBY
to return to hand steering, or
AUTO
to return to Auto.
Note:
The waypoint advance will only operate on pilots receiving valid
bearing to waypoint and waypoint number information.
