Connections:
The FADEC have 3 types of connections:
Power connections:
Two high quality MPX connectors
carry all the power current.
Each power lead is identified by the label on the
FADEC body.
The female MPX plug provides the power to the
glow plug and starter motor. Use 0,5mm flexible
cooper lead if the length is up to 0,5m, and 1mm
if higher for Gas start engines, 1mm2 minimum
for Kerostart burner. Both negative leads are
connected to same place inside the FADEC, so it is possible to use only 3 leads to the
engine, sharing the negative between starter and glow plug. Take care of doing a neat
installation to avoid short-circuits, specially in the starter connection, it is very easy that
the soldering in the red lead touch to the starter cover in some engines.
The male MPX plug provides the connection
to the pump and the battery. Use minimum
0,5mm cooper lead for the pump and 1mm
for the battery. Keep all connections well
isolated between them, and be sure to not
reverse the battery polarity, the fadec will
be burned out immediately. The battery
voltage should be of around 7,2V, either 2s
Lipo or 5 cells Nicd/Ni Mh for Kerostart.
Gas start allows the use of A123 2s cell
(6,6V).
DATA Connection:
One 3 pin servo socket, placed on the left side of the
FADEC, provides the connectivity to the handheld
data terminal or a PC.
Signal connections:
4 JR type receptacles provide the connection to the
RX and sensors
