3.5. ECU / Relay Box
Install the ECU so that the rear of the ECU is ventilated by cool ambient air. This
arrangement is necessary to drain the heat from active components .
Max. temperature on ECU housing: 90°C.
Install the relay box and contacts such that they are protected from spray.
Moisture will cause contact problems!
4. Engine Operation
Read the manual before operating the engine!
Note:
Always adjust engine RPM so that the engine runs smoothly.
Make sure that the centrifugal clutch does not “drag”. Avoid the 4100-4200 RPM
range as engine operation is not as smooth as at other speeds.
4.1. Ignition / Warming-up
Complete the daily check (see 5.1) before switching on the engine.
To start engine:
Fuel valve:
Open
Throttle:
Idle position (fuel/air mixture is controlled electronically)
Main switch:
On
Ignition:
On
Starter:
Operate
As soon as the engine starts, throttle up sufficiently so that the engine runs
smoothly in conjunction with the resonance frequency of the cell/propeller.
Never operate the engine for long periods at low RPM (with stationary
propeller) so as to provoke overheating situations.
If water temperature touches 100°C on ground, increase engine RPM to
2000 for better cooling!
Allow engine to warm up at about 2000 RPM.
After 2 minutes, engine RPM can be raised to 2500 RPM until all temperatures
have reached minimum operating temperatures (water: min. 60°C, oil min 60°C).
After taxying to the holding point, apply brakes and set the engine briefly to full
power. Check that manifold pressure increases to between 0.7-1 bar (60 KW) or
1.2 to 1.4 bar (74 KW). The SMART-MIP will indicate total pressure, so at the
time of this check, it should indicate 1.7 to 2 bar (60 KW) or 2.2 to 2.4 bar (74
KW).
If manifold pressure does not increase, abort takeoff immediately
,
determine the cause of the fault and correct.
Monitor oil pressure at all times .
