PROBLEMS SOLUTIONS
There is no reading on the screen 1. Disconnected receiver or the ecu/receiver batteries are
empty
2. The display is connected to the wrong port or reversed
3. Problem in the ecu or display
The kerosene does not ignite 1. Check fuel flow. Disconnect the fuel line from the
engine, launch a startup and check while “ignition” is
displayed if there is fuel pump by the pump. If not, pump
problem. Pump RPM should be between 75 and 125rpm.
2. The battery is discharged. Check that the reading of
battery voltage in the terminal keeps above 7.0V during
ignition phase.
3. Fuel blockage. Check if the start valve “click” using test
menus. Blow using a piece of tube to check that the fuel
path is not restricted.
4. Glow voltage needs adjustment. Increase by 0.2 and try
again. Do not use a voltage higher than minimum
necessary to avoid to shorten the glow plug life.
There is little increase of RPM
when the
fuel ignites
1. There is air in the line of fuel
2. The filters are blocked
The engine reduces the power or it
is
stopped during starting
1. The ecu has detected temperatures
over 800ºC due to too slow starting
2. There is low battery or air in the
tubes- Therefore let it cool and retry
Engine does not accelerate to
maximum set
Rpm or “PUMP LIMIT/overload”
reading is displayed
1. There is insufficient fuel flow or air bubble
entering the engine during the initial start up.
Check suction side of pump.
2. The radio is not correctly adjusted.
The engine loses power in flight 1. The ECU battery is empty: recharge
2. The filters are dirty
The engine stops in flight 1. The fuel level is low and/or there is air
in the pipes
2. There is a poor connection between the
battery and pump
3. Interference/failsafe
4. Check the “last power down” cause on the ecu
There is excessive vibration and
unusual noise
1. The engine is unbalanced by the ingestion of a foreign
object. Do not use the engine and send it in for service.
