POSSIBLE CAUSE and SOLUTION
The autopilot is unable to turn the rudder (this occurs if the weather
load on helm is too high, or if the rudder position sensor has passed
beyond the preset rudder limits or rudder end-stops).
Check drive and rudder position sensor.
Check the drive wiring is correctly connected.
Supply voltage has dropped below acceptable limits.
To respond to a Low Battery alarm:
• press standby to clear the alarm and return to hand steering
• start the engine to recharge the battery
AutoLearn not completed successfully.
Failure codes:
1
= AutoLearn has not been carried out (default setting)
2
= AutoLearn failed, usually due to manual interruption
4
= AutoLearn failed, probably due to drive or compass failure
Repeat the AutoLearn procedure.
Motor cables are connected to power terminals (and power cables
are connected to motor terminals) at the computer. Turn off power
and swap over connections.
Caused by any of the following situations:
• the compass is not connected
• the autopilot is in Wind Vane mode and it has not received wind
angle data for 30 seconds
• the autopilot is in Track mode and:
• the autopilot is not receiving SeaTalk navigation data, or
• the position sensor is receiving a low strength signal – this will
clear when the signal improves
Check the connections to the compass and/or wind instrument
and/or navigator.
Note: The autopilot stops adjusting the heading as soon as it loses
data.
The controller is not receiving data from the SmartPilot computer.
Check connections and check the SmartPilot computer is switched
on.
GyroPlus yaw sensor has failed:
• If you have a S1G, S2G and S3G system with internal GyroPlus sen-
sor – call a Raymarine service agent.
If you have a Non-G computers with external GyroPlus yaw sensor
– check the sensor and connections, then call a Raymarine service
agent.
