Alarm/Warning
Position data missing
Rudder data missing
Rudder limit
Possible cause
Position data from the GPS is missing.
Rudder angle signal to autopilot
computer is missing.
The set rudder limit is reached or
exceeded. Might be caused by
disturbance to compass (waves), speed
log, sharp turn or improper parameter
setting.
Recommended action
• Check that the GPS antenna has a clear view of the sky
• Check device list for valid position source
• Try a new automatic source update
• Check cables and connections
• Check that the GPS antenna is not covered by ice, snow or
any other objects weakening the signals from the satellites
• If several rudder angle sensors, check which port on the
board that is set up for use
• If the missing sensor is connected to an autopilot
computer, check cabling
• If missing sensor is a CAN device, check network
connection
• Check mounting is correct and that the center position of
the feedback lines up with the center position of the rudder
and that the rudder movement is within the operational
range of the feedback
• In the case of Frequency feedbacks, and long cable runs,
external electromagnetic disturbance may affect the signal
in rare and extreme cases
• Notification only
