2.
Ready:
Indicates that the engine is ready for starting, and that the transmitter signal cor-
responds to IDLE, (LED lit twice)
3.
StickLo!:
This indicates that the throttle stick is in a position above IDLE, the engine will
not start with the stick in this position.
4.
Glow Test:
Verification of glow plug
5.
StartOn:
Test of the starter and rpm sensor
6.
Ignition:
Ignition phase.
7.
SwitchOver:
Phase of heating of the combustion chamber after detecting the ignition.
8.
FuelRamp:
Phase of acceleration until idle speed.
9.
Run Idle:
Engine working correctly, pilot have full control of engine power, command re-
ceived from transmitter is IDLE.
10.
Running:
Engine working correctly, pilot have full control of engine power, command re-
ceived is an intermediate setting between Idle and Full Power.
11.
Run-Max:
Engine working correctly, pilot have full control of engine power, command
received is Full Power
12.
Cal-Pump:
Pump is being calibrated, usually at full rpms. Hold throttle steady a few sec-
onds until it is finished.
13.
Stop:
Engine off.
14.
Cooling:
Starter is operating to cool the engine.
15.
GlowBad:
Defective or disconnected glow plug.
16.
StartBad:
Insufficient RPM reached during start, RPM sensor damaged, too thick oil used
on previous run causing excessive bearing drag, no cooling sequence done in previous run, no rpm
signal, defective starter.
17.
Low RPM: Engine had been shutdown because the speed has fallen below the minimum.
Usually lack of fuel (bubble)
18.
HighTemp:
Excessive temperature.
19.
Battery!:
battery voltage out of limits.
20.
Pump Overload:
There is a restriction in the fuel path from the pump to the engine, or in
the engine itself, possibly the fuel valve partially closed or semi blocked.
21.
No Data:
Means that the data terminal is not receiving any data from the engine. Usual
causes are battery disconnected, Data Terminal in wrong port, throttle lead connected in wrong
port, pump lead reversed
Diagnoses:
During engine operation the ECU measures and stores all the engine operating parameters record-
ed during the last the 51 minutes of operation. These measures can be downloaded later to a PC
to study the behaviour of the engine in flight and to diagnose any possible problems. Also, after
each cycle of operation, the ECU stores the last cause of shut down and the values of RPM, tem-
perature and pump power.
In order to access these measures, it is necessary to shut down and power-up the ECU. Set the
trim down (trimLow) and push the left button on the display. The ECU will show the cause of last
shutdown and the parameters value at the moment of shut down.
These are as follows:
