6 Errors and faults, troubleshooting
6.1 Indicated errors and faults
The FLAPS V6 HBR control unit can indicate up to 4 types of serious faults. The table
below lists these faults, their indications, and a more detailed description. Individual errors
are indicated by orange blinking of the LED and the other LEDs are red.
Blinking can be slow (1x/s ) or fast (5x/s ).
Indication Fault name Description & Cause Solution
Programmed
Positions
Error
The programmed
positions of the target
positions are shuffled or
overlapped. It often
occurs when
reprogramming target
positions mirrored
against factory preset.
Reprogram all target
positions one after the
other so that the positions
of the target positions go
gradually and do not
overlap (i.e. positions on
the piston rod distance
<2mm)
Position
Sensor Fault
Poor connection, short
circuit, or disconnection
of the position sensor
circuit. This may be due
to a fault in the wiring
or the position sensor,
in rare cases in the
control unit.
In flight, turn the switch to
position 1 or 2 to activate
the Safety Manual mode
(see Chapter 5.3).
On the ground, check the
wiring and functionality of
the position sensor.
Error
Low Voltage
Weak battery or long
leads to FLAPS V6 unit
with too high voltage
drop at high actuator
load
Check the current-carry
dimensioning of the on-
board power network,
battery condition, shorten
the leads to the FLAPS V6
unit, the leads to the
actuator (if necessary,
increase the cross-sections
of the wires if the leads
cannot be shortened)
Error
Undervoltage
Low battery or wiring
fault
Check the wiring, the
current-carry dimensioning
of the on-board power
network, battery condition,
shorten the connections to
the FLAPS V6 unit, the
connections to the actuator
(if necessary, increase the
wire cross-sections if the
leads cannot be shortened)
