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 .
