SmartController Alarm messages

When the SmartController detects a fault or failure on the system, it will
activate one of the alarm messages listed in the following table.
Unless otherwise stated, you should respond to the alarm by pressing
standby to clear the alarm and return to manual control, before you
attempt to resolve the problem.
In some situations, the SmartController will raise more than one alarm.
When you have dealt with the first alarm, it will display the next alarm.

POSSIBLE CAUSE and SOLUTION
See the main autopilot display head for infor-
mation on this alarm.
Serious drive failure – the drive is taking too
much current due to short-circuit or jamming.
Check the drive unit.
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.
This alarm will sound when you are more than
0.3nm from your planned track. The alarm will
also state if you are to the PORT or STARBOARD
of the track,
AutoLearn not completed successfully.
Failure codes:
1 = AutoLearn has not been carried out
2 = AutoLearn failed, usually due to manual
interruption
4 = AutoLearn failed, probably due to drive or
compass failure
Repeat the AutoLearn procedure.
