” RPM Fuel Ramp K”
. Set the rotor RPM where the fuel will be feed only to main
injectors only and the burner switched off. Typical values 6.000-12.000 RPM
” Pump Start point”
Set the start power of the pump. Exactly same as gas start.
”Glow plug power”
Set the voltage of the burner
” Engine min.Flow:”
Set the percentage of time of the main fuel valve is open at beginning
of the switchover phase. This percentage will increase automatically with RPM until arrive
to fully open when the RPM of next phase are reached. The time where the burner valve is
open is complementary to the injector time, so when the main valve is open at 80%, the
burner is 20%. Typical value 50%-70%
8) Fuel Ramp: From here the startup progress like gas starts. Parameters used on this
phase are exactly the same with same use, please read the”Gas start” sequence from point
nr.8.
List of FADEC STATUS message codes
Here is a list of possible messages shown on the data terminal screen and their meaning.
TrimLow
:
Indicates that the signal received from the transmitter corresponds to the
lowered trim, that is to say, engine OFF.
Ready
:
Indicates that the engine is ready for starting, and that the transmitter signal
corresponds to IDLE, (green LED lit)
StickLo!:
This indicates that the throttle stick is in a position above IDLE, the engine will
not start with the stick in this position.
Glow Test:
Verification of glow plug
StartOn:
Test of the starter
Ignition:
Gas ignition phase.
Preheat:
Phase of heating of the combustion chamber after detecting
the gas ignition.
FuelRamp:
Phase of acceleration until speed of IDLE.
Running:
Engine working correctly, pilot have full control of engine power.
Stop:
Engine off.
Cooling:
Starter operating to cool the engine.
GlowBad:
Defective or disconnected glow plug.
StartBad:
Defective starter, insufficient RPM reached during start, RPM sensor failure.
Low RPM:
Engine speed below the minimum.
HighTemp:
Excessive temperature
FlameOut:
Exhaust GAS Temperature below the minimum.
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 have increased the pump power up to the value set on
the
“Pump Limit”
parameter, but the engine hasn’t arrived to full power. Causes could be
flat battery, fuel restriction or anything that can cause a reduction in the fuel flow.
x
xxx OVERLOAD
: A excessive current is detected flowing to the specified output.
