The standard position of the left flip switch is ”AUTO“, for the right flip switch it is
“STOP“. The propeller RPM set with the rotary switch will be held constant
during the flight.
If the left flip switch is set to ”MANU“ and the right flip switch is set to ”HIGH
RPM“ (T/O setting), then the propeller will remain in flat pitch. The green
indication light indicates that the propeller is in the T/O setting (flattest pitch).
To change the propeller pitch to the glide setting, set the left flip switch to
”MANU“ and the right flip switch to ”FEATHER“. To leave the glide position, set
the left flip switch to ”MANU“ and then set the right flip switch to ”HIGH RPM“
(T/O setting). The propeller reaches the final pitch after 90 s. After the propeller
has moved out of the glide setting (a green indication light will go ON and the
propeller starts to windmill) and after restart of the engine, set the left flip switch
to “AUTO“ and the right flip switch to “STOP“. Now select the desired propeller
RPM with the rotary switch.
The installed control unit will perform a self test once it is supplied with electric
power from the electrical system. The unit can be used once the yellow and
green indication lights FLASH for several seconds.
If the yellow indication light flashes during operation or other indications of
malfunctions are given, follow the procedures of chapter 3.13.1.18 and contact
the manufacturer.
