Alert Message
Meaning
End condition
OAT SENSOR NOT
DETECTED
This alert appears when the EFIS-D10A has an
OAT connected and then loses that connection for
some reason. Either the EDC-D10A has become
disconnected, or the OAT sensor itself has become
disconnected from the EDC-D10A.
Double-check your wiring between the EFIS-
D10A and the EDC-D10A as well as that of the
OAT sensor.
REMOTE COMPASS
NOT DETECTED
The EFIS-D10A is unable communicate with the
EDC-D10A. If you have an OAT connected to
your EDC-D10A, it will not be displayed either.
Ensure that you a) have an EDC-D10A installed
and b) have verified that the wiring to the EDC-
D10A is correct. Please see the EFIS-D10A
Installation Guide for more information on
verifying the installation of the EDC-D10A.
This error also can appear if you have updated the
firmware in your EFIS-D10A while the remote
compass was
not
connected. If this is the case, try
uploading the new firmware again with the EDC-
D10A connected. Attempt the connection within
the first few seconds of operation.
Note that the EFIS-D10A does not have internal
magnetic sensors and thus
requires
the EDC-D10A
be connected.
TEMPERATURE
UNSTABLE
When the unit is turned on after having been off
for a long period, its internal temperature rises
above ambient at a fast rate. This fast change in
temperature can sometimes reduce the reliability of
the output of the sensors. Therefore, this alert is
displayed and the horizon indication is changed
from blue/brown to grey/black.
The alert is cleared when you press any of the
buttons. The screen remains grey and black until
the temperature within the unit has stabilized. This
temperature instability should last no longer than 2
minutes. For this reason, it is a good idea to turn
the unit on before you run through any of the
preflight procedures, so that it will be ready by the
time you are ready to fly.
