9-1.7 System Description
The IVO variable pitch propeller is controlled by a spring-loaded rocker switch labelled FINE
and COARSE. Propeller pitch adjustment is controlled by an electronic circuit which
provides system status indication using two status indicators (orange LED). Status
indication logic and corresponding system status is described in the following table:
Status Indicators (orange)
System Status Propeller Pitch Control
Both LEDs off No pitch change
Upper LED flashing Propeller changing pitch to FINE
Upper LED steady on* End position FINE reached and electronic pitch
change inhibit FINE activated. LED goes out after 3
seconds (beginning with version 1.2)
Lower LED flashing Propeller changing pitch to COARSE
Lower LED steady on* End position COARSE reached and electronic pitch
change inhibit COARSE activated LED goes out
after 3 seconds (beginning with version 1.2)
Both LEDs flashing fast
synchronously**
Actuating motor does not work despite rocker switch
activation. Possible defects: brushes worn out, cable
break, motor defect …
Both LEDs flashing fast
asynchronously**
An error occurred at least three times. Operation is
not affected (beginning with version 1.3)
