ALARM MESSAGE POSSIBLE CAUSE and SOLUTION
CURRENT LIMIT
Serious drive failure – the drive is taking too much current due to
shortcircuit or jamming. Check the drive unit.
DRIVE STOPPED
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 endstops).
Check drive and rudder position sensor.
LOW BATTERY
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
LRN FAIL 1
,
2
or
4
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.
MOT POW
SWAPPED
Motor cables are connected to power terminals (and power cables
are connected to motor terminals) at course computer. Turn off
power and swap over connections.
NO DATA
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 (GPS, Loran, Decca) is receiving a low
strength signal – this will clear when the signal improves
Check connections to the compass, wind instrument and naviga
tor.
Note:
The autopilot stops adjusting the heading as soon as it loses
data.
NO PILOT
The controller is not receiving data from the SmartPilot computer.
Check connections and check course computer is switched on.
NO RUDREF
Possible fault with rudder position sensor – check connections.
