OTHER FAULT WARNINGS
The following warnings are given by the audible alarm, together
with information in the INFO display:
OUT OF COURSE
RESET ALARM
This alarm will occur when course deviation is greater than the
selected OFF COURSE LIMIT.
Cancel the alarm by pressing the ALARM RESET button.
If required, the OFF COURSE LIMIT can be readjusted.(Press INFO
once, press INCREASE to adjust value).
COMP DIFF
RESET ALARM
Note !
This alarm appears only if two compasses are connected.
This alarm will appear if the difference between the MAIN compass
and the MONITOR compass reading is more than the set value of the
OFF COURSE LIMIT.
Normally the MAIN COMPASS is a gyro (True Heading) while the
monitor compass is magnetic (Magnetic Heading). Deviation and
Variation may cause the difference to exceed the pre-set OFF
COURSE LIMIT.
Press the ALARM RESET to cancel the alarm. This will at the same
time compensate for the present difference between the two
compasses.
COMMUNICATION
FAILURE
Serial lines make all internal communication between the two
stations in a DUAL STATION system. A failure in the
communication is given by this warning.
RUDDER FEEDBACK
FAIL
This alarm shows that the autopilot does not read the Rudder
Feedback Unit.
The AP9 MK3 has, however, a built-in simulated feedback signal that
will substitute the feedback signal.
