If the autopilot is restricted by a low rudder limit, this text will be
displayed.
Press ALARM RESET
This will switch on the simulated feedback signal shown in the INFO
display as a continuous flashing text:
SERVICE IS REQUIRED BY AN AUTHORIZED DEALER
In case rudder angle indicators are connected to the rudder feedback unit,
Note !
they may also be out of order.
This alarm will appear if the rudder does not respond to a given
rudder command.
Check that the steering gear is switched on and that any system
change-over switches are set for autopilot steering.
The reason may also be related to a failure in the steering gear system
or the autopilot drive signal switches (solid state PCB in the D9X
unit).
No Navigational Steering can be made if this fault warning should
appear.
Check that the nav. receiver is switched on and properly set to
provide the NMEA signals:
Cross Track Steering (XTE): APA, APB.
Course to Steer (CTS): BOD, BWC, BWW, BWR.
Also check the autopilot nav. settings in INFO-loop 2.
This fault warning indicates that the reception conditions are poor.
The same warning can also be given during Nav. mode operation of the
Note !
autopilot when a waypoint is reached. The given heading from the nav.
receiver is then to be set on the autopilot in AUTO mode before switching
back to Nav. steering (XTE).
