LOW POWER
ERROR
The autopilot has detected that its input voltage has
dropped under 10 VDC.
Check for proper alternator operation, batteries low on water, or
some other condition that has caused the input voltage to drop.
NO COMPASS DATA
ERROR
The computer is not receiving any data from the
compass.
Check that the compass is plugged into the autopilot. The autopilot
is operable in non-autopilot modes only (i.e.
STANDBY
or
POWER
STEER
). Check that the autopilot is programmed for the correct
type of compass (see DOCKSIDE SETUP for information).
NO DATA FROM
NAV DEVICE ERROR
The autopilot is not receiving any recognizable data
from the Nav Device.
This could be because 1) the Nav Device is not programmed
correctly; 2) the Nav Device is not putting out any data; 3) there is a
problem with the cabling between the Nav Device and the autopilot
( i.e. broken or reversed wires); or 4) there is a fault with the
autopilot interface circuitry. Some Nav Devices will not put out a
data sentence for the autopilot until a waypoint has been entered,
and navigation towards it started.
NO SPEED ERROR
The autopilot is in the PILOT or NAV mode, the speed
sensitive selection of the FAST or SLOW operating
modes is turned on and the autopilot is not receiving
any speed information from the navigation device.
Check that the device transmits one of the RMA, RMC, VBW, VHW
or VTG data sentences and that it is turned on. Check the cable
which connects the navigation device to the autopilot distribution
box, especially if you get a No Data error when the autopilot is in
the NAV mode.
PROM MEMORY
ERROR
The memory chip, which contains the autopilot
program, tested faulty.
The autopilot is not operable.
