Possible causes
• The autopilot is in Wind
Vane mode and has not
received wind angle data for
32 seconds.
• The autopilot is in Track
mode and is not receiving
navigation data, or the rudder
angle sensor is receiving a
low-strength signal. This
will clear when the signal
improves.
Autopilot components are
initializing.
The autopilot is in Wind Vane
mode and has not received
wind angle data for 32 seconds.
The autopilot has not received
speed (STW or SOG) data for 10
seconds, while in Auto mode.
The EV-1 or EV-2 is not
receiving heading data.
The internal rate gyro on the
EV-1 or EV-2 unit has developed
a fault. This will be evident
as a compass issue and could
cause the compass heading to
deviate or lock-up.
On the Evolution ACU unit, the
motor cables are connected to
the power terminals, and vice
versa.
A source of GPS data is not
connected to the SeaTalkng ®
system.
A fault has occurred with the
joystick. This alarm applies
only to autopilot systems that
include a joystick controller.
Loss of communications
between the EV-1 and ACU, or
EV-2 and drive interface unit.
Solution
Check the connections to the
wind transducer, multifunction
display, and autopilot control
head (as appropriate).
Some components may take a
moment to startup.
Check the connections to the
wind transducer.
Check the connections to
the speed transducer. Pilot
does not require speed data
in order to operate. However,
it does enhance the overall
performance when in Auto
mode.
• Check the connections to the
EV-1 / EV-2.
• Power cycle the EV-1 /
EV-2, by removing and then
reconnecting the SeaTalkng ®
cable.
If the problem persists, contact
your local Raymarine service
center.
Switch off the power to the unit
and reconnect correctly.
Check connections to the GPS
data source.
Check the connections to, and
operation of the joystick.
Check all physical data
connections between these
devices, as appropriate.
