Priming the fuel system
Priming is achieved by a special menu on the ecu. Set the trim to low and go to “Info” menus and next to “Pump
test”. Click on “on” / ”off” to start/stop the pump manually. Please observe fuel line to engine very carefully and
push the off button to shutoff as soon as fuel reaches engine. Repeat the same operation on the burner line by
the appropriate menu.
IMPO RT A N T:
The prime procedure should be done only to fill the fuel tubes and filters in the case of
a first installation or in case of disas s e mbling of the tubes. Do not run the prime function so that the
engine becomes flooded by fuel, as this will cause an uncontrolled fire at next startup.
Starting the engine
Set the throttle stick down and the trim up. “Idle” - Confirm that the green LED in the ecu is illuminated and the
screen shows “Ready” -
!Ready to start!
Move the stick to 50% and then back to idle again. The Ecu will begin the startup sequence as described below:
First the internal glow plug will be energized. After 6-10 seconds, depending on the engine temperature and
battery charge, the starter will be powered up to have the rotor turning at 3000 RPM.
Once the rotor is at speed, the pump and solenoid valves will be energized in pulsating mode. Few seconds later
the kerosene will ignite and the exhaust temperature will begin to increase. The rpm and pump power will
increase automatically. During this phase the data terminal will display “IGNITION”.
When the exhaust temperature is of around 70ºC, the data terminal reading will change to “SWITCHOVER”, during
this phase the fuel will be routed to main injectors and the speed of the rotor will be progressively increased to
10,000 RPM.
Once this phase is finished, the reading will be “FUEL RAMP”. In this phase the engine receive fuel only trough its
normal fuel input, and internal glow plug iwill be disconnected . The fuel flow and starter power will be increased
automatically to increase the RPM up to idle RPM. When 25.000 RPM is reached the Ecu will automatically
disconnect power to the starter.
When the rotor speed reaches idle, the screen will change to “running” and the engine speed is stabilized.
The engine is running!
Control of engine power/rpm is now handed back to the transmitter and controlled by the position of the throttle
stick.
Increase/decrease the throttle slowly, verifying that the engine accelerates/decelerates.
Take special care
around the engine intake, keep your hands at a safe distance along with any other objects as they can
be easily ingested.
Engine shut down procedure:
To shut down the engine lower the trim and the stick. Is recommendable that before shutting down the engine
please restrain the model then raise the throttle stick to approximately 25%, allowing temperatures to stabilise
for around 5 seconds before carrying out the shutdown procedure.
Both main fuel and starting fuel lines need purging of all air after initial installation. Take extra care when priming
the lines, ensure that NO fuel is pumped inside the engine. To do so, disconnect the fuel lines from the engine
wile priming.
