4.4.2. Starting
The Start Mode is automatically initiated when the Jet Control toggle
switch is moved to the RUN (top) position. The Jet Electronic Control
Unit (ECU) automates the following start sequence:
Switch glow plug on
Starter motor spools up compressor
Fuel is introduced in the starter fuel line
Fuel supply to the engine is handed over from the start line to
main fuel supply line.
Starter motor is disengaged
ECU ramps engine up to idle RPM (30 000)
During Start Mode the Status LED (the top LED) will be flashing
green.
CAUTION:
Do not advance the throttle to a high RPM setting during
the start sequence. A ramp-up flame-out may result,
especially at higher density altitudes. It is also good
practice to allow the engine temperatures to stabilise
while at idle, before advancing the throttle to higher
power settings.
NOTE:
A displayed EGT exceeding 1000°C (1832 °F) may be
briefly observed during startup. This high temperature
may only exceed a set temperature for a limited time, as
determined by the engine manufacturer.
