List of FADEC Warning message codes:

RC SIGNAL LOST/INCORRECT: The signal received from the RX is wrong (outside

calibration margin) or absent.

PUMP LIMIT REACHED: The FADEC has increased the pump power up to the value

set on the “Pump Limit” parameter, but the engine has not arrived to the full power.

Causes could be flat battery, fuel restriction or anything that can cause a reduction in

the fuel flow.

xxxx OVERLOAD: An excessive current is detected from the specified output.

Diagnoses

During engine operation the FADEC measures and stores all the engine operating

parameters recorded during the last the 51 minutes of operation. These measures

can be downloaded later to a PC to study the behavior of the engine in flight and to

diagnose any possible problems. Also, after each cycle of operation, the FADEC

stores the last cause of shut down and the values of RPM, temperature and pump

power at the moment of shutdown. In order to access these measures, it is

necessary to reinitialize the FADEC (shut down and powerup).

Set the trim down (TrimLow) and push the left button on the display. The FADEC will

show the cause of shutdown and the measured values at the moment of shut down.

These are as follows:

Diagnosis messages:

UserOff: The engine has been shut down because it has received the shut down

command from the transmitter.

FailSafe: The engine has been shut down because of loss of signal from the

transmitter. Once Ecu detects a loss or invalid RC signal for over 0.5 second, it sets

engine power to idle, and if after another 1.5 seconds a valid signal is still not

received the engine is shut down.

LowRPM: The engine has been shut down because the RPM has dropped below a

minimum. Cause could be lack of fuel, air bubbles, problem with the batteries, or

defective RPM sensor.
