2. Ignition switch
Position UP: -
Ignition ON
-
The power plant extends completely (automatic mode)
-
Electric fuel pump is switched on
-
Electric cooling water pump is switched on
Position DOWN:
-
Ignition OFF
-
The power plant retracts automatically as soon as the engine
is stopped and the correct propeller position is reached
(automatic mode)
-
Electric fuel pump is switched off
-
The electric cooling water pump is switched off when the
cooling water temperature has fallen below 60°C
Note:
When the power plant reaches the fully extended position with ignition ON but is not
started, after a short period of time the electrical fuel pump and the cooling water pump
will be shut off (energy saving mode).
As soon as the starter button is pressed, both devices are switched on again.
3. Memory Card Slot
The memory card reader built into the MCU3 operating unit accepts Micro-SD cards.
Using this interface, error data can be transferred to an SD card and, for example by e-
mail, transferred to the manufacturer for analysis. In addition, a software update for the
operating unit and the power plant control system can be imported via this interface if
required.
