engages and holds the propeller until the engine is retracted.
Note: Option level II (no on-off switch):
Electrical aligning of the propeller (only in conjunction with
Option Level I).
If the propeller after stopping is not in the retraction position, it is possible
to turn the propeller slowly with the starter motor into retraction position by
pressing the starter button. The starter motor speed is reduced by electronic
means during this procedure. This procedure is not possible on the ground
due to the slow starter motor speed.
33) a) circuit breaker 15 A for the engine
extension - retraction motor
b) fuse 6 A for the DEI and for the
electric brake, see item 32 option level I
c) fuse 4 A for the 12 V socket
d) fuse 2,5 A for the radio
e) fuse 2,5 A spare fuse for turn –
and bank indicator or horizon
f) fuse 1 A for the electric variometer
g) fuse 10 A for the generator
All the above fuses b) - g) are G fuses 250 V with indicator 5 x 25 medium
slow. The coloured indicator can be easily seen through the glass top of the
fuseholder when the fuse is blown.
34) Engine elapsed time indicator
The engine elapsed time indicator is connected to the generator and
operates only when the engine is running and when the generator fuse
(33 g) is in.
Installation can also be in the instrument panel or in the relais compartment
access cover when oxygen system instrumentation is installed in the side
panel.
35) Change over switch from static pressure to total energy pressure for the
variometer (Option), only in front cockpit.
up stat = Vario operating on static pressure
= for engine running flight
down T E = Vario operating on total energy probe
= soaring flight
36) Change over switch - soaring flight - engine on flight
up Avionik + = The total electrical system is
engine on line
down Av = only soaring flight instrumentation, radio and 12 V
socket No.22 on line.
