An autopilot is a complex system. Its performance depends on a
proper installation and a successful sea trial.
In the event of an autopilot failure, the AP50's numerous test
features will assist you in isolating a probable fault.
Audible and visual alarm is provided for every fault being detected.
The audible alarm is reset by pressing any button (e.g. by
changing mode from AUTO to STANDBY). All visual alarms
will remain and alternate with the operating display until the
fault has been rectified. If an external alarm buzzer is installed
(Refer to the Installation Manual, External Alarm) the external
alarm will be given 5 sec. after the internal. Refer to the table
below for hints if you would like to try and solve the problem
yourself. However, most of the problems may require the
assistance of a Simrad dealer.
Perform any repair actions in the listed sequence.
For AP50 Plus system, the J50 boards are located inside the
JD5X Distribution unit.
'Compass difference', 'Vessel off course', and 'Rudder limit'
warnings are automatically reset when the error is rectified.
