Switch Error: wrong consecution of switches during powerplant extension
If the DEI-NT has detected a wrong sequencing of the limit switches during
powerplant extension, the powerplant will not be retracted automatically after
stopping the engine, but the system switches over to manual operation and
„Switch Error" and the "hand" symbol will be displayed on the centre display.
There is a possibility that the powerplant doesn't stop in the position where the
propeller should stop turning and the still turning propeller hits the propeller
stopper.
If the pilot can't detect any failure he may confirm the warning and reactivate
the automatic retraction (switching the ignition on and off), but not before the
propeller stops turning.
Error of the switch operated by the propeller-stopper, (no failure message)
It might be possible that the propeller stops just above the propeller stopper and
presses on the stopper during powerplant retraction into the position where the
stopper moves forward. The stopper can't move forward and operate the switch
in this position.. To avoid any damage the powerplant will not retract
completely. To accomplish this the DEI-NT checks within 3 seconds if the
switch has been operated. If not, the powerplant will be extended automatically
to the powerplant position where the propeller usually stops turning.
Rotate the propeller out of this position by pressing the starter button, further
powerplant retraction is as normal.
Note: only in this special case is it possible to rotate the propeller with the
starter motor in this powerplant position (position where the propeller usually
should stop turning).
