The following fault warnings may be shown on the Information Display:

 

 

OFF COURSE

 

 

 

RESET ALARM

 

 

Course deviation is greater than selected off course alarm limit. Press the Alarm

 

button to cancel the alarm. The alarm is automatically reset when the vessel is

 

back within the limit.

 

 

 

 

RUDDER FEEDBACK

 

 

 

FAIL!

 

 

Indicates that the autopilot is not reading rudder feedback signal. By pressing the

 

alarm reset button, the audible alarm will be reset and the autopilot will switch to

 

a simulated signal, instead of the real. This is indicated by a flashing * * SIM * *

 

on the information display. Repair actions should be taken when back in port.

 

 

NO RESPONSE

 

 

 

FROM RUDDER

 

 

If a rudder command is not executed, or the rudder moves in wrong direction, this

 

message will be shown on the display. The reason can be a malfunction of the

 

steering gear, or simply that the steering gear is not switched on.

All three messages indicate problems with reading the signals from the navigation receiver. If you are unable to cure the problem, the NAV-mode should not be used before a Robertson dealer has been consulted.

These alarms will be given when the autopilot is unable to detect a proper signal from the selected heading sensor. The reason can be a faulty sensor or wrong selection of sensor (See “Type of Heading Sensor”, page 6-4).

DATA FAILURE

CHECK SETTINGS

If the autopilot should lose or read erratic data stored in the memory, this alarm will be given, and the autopilot is simultaneously set to MANUAL-mode.
