Manual mode:
From values from 9 to 255 the power applied to the pump is fixed.
It is necessary to test with the selected pump and battery the right value to have the
pump to start at the desired speed.
P
ump Start ramp
: This parameter adjust the speed
of the fuel increase during the “Fuel ramp” phase.
Higher values mean a faster fuel flow increase.
Increase this value if the engine takes too long to arrive to idle, and decrease it if the
starts are too hot, with the engine overshooting the idle speed.
Auto Start mode. GAS:
Ensure your engine operates correctly before attempting full auto-start operation. You
can run the engine using the FADEC in manual mode, see “Manual Start mode
”
section.
Keep the magnetic RPM sensor clear of stray magnetic sources such as fuel pump and glow
plug wire as the magnetic field generated can upset the rpm reading.
Ensure your starter operates smoothly and without sticking. You should be able to attain
at least 1/3 of the idle RPM when the engine cold and 2/3 of the idle RPM during the
engine starting with the starter powered directly with the battery.
Ensure that the filament of your glow plug is well exposed out of the plug to ensure
prompt gas ignition.
A restrictor is sometimes required to control the flow rate of the start gas, especially if
pure propane is used. Gas supplies must be gas only, dip-tube liquid feed types are not
suitable. Propane/Butane mixtures work well in temperate climates. Beware of using too
much gas in the belief this will ignite more easily. Keep the maximum gas pressure under 2
bar (25psi) to avoid damage to the solenoid valves.
Problems lighting the gas are mostly related to plug element exposure, ensure the element
is pulled clear so the gas can really “see” the element. It needs to glow bright yellow for
good ignition, so adjust the “glow power” voltage in the main menu as required.
If necessary, prime the fuel circuit using the “pump test function” on the INFO menus.
Stop the pump when the fuel arrive close to the engine (10-20 cm) but avoid to fill the
engine with fuel. Use this option only to fill the tubes after servicing, but not at each
start.
Always
set-up and confirm the operation of your Auto-start installation on the
test-stand, before installing into your model.
The present version of Autostart uses only one channel for all of the engine
functions: To trigger the autostart cycle, the process is as follows:
1.
The user raises the trim. "Ready" will appear on the HDT (Hand data terminal)
screen. The trim and stick should be where the engine is supposedly to be to idle
once running. If the trim is on "stop" position, "Trim low" will be read on the HDT.
If higher than idle, "StickLo!" will be read.
