Example 3
Using a three-position external switch (Differenti-
al switch, Order No. 4160.22)
This variant implements a multi-stage switching sys-
tem for the drive motor using the OFF – half-throttle –
full throttle method. At the receiver end you require a
proportional speed controller.
The settings required for this are basically as descri-
bed under Example 1, and the same notes and re-
commendations apply.
The only area which differs from the previous descrip-
tion is the method of assigning the selected three-po-
sition switch, which is carried out in the menu ...

Here again you move to the line for the fl ight phase-
independent input "9" with the rotary control pressed
in. As in Example 2, you now activate the switch sym-
bol in the second column, adjacent to SEL, with
a brief press on the rotary control, and then opera-
te the selected three-position external switch, e.g. "7".
Move the switch from the desired half-speed position
(i.e. the centre position) to the full-throttle position.
Now activate the left-hand switch symbol which is
present in the same column. Move the three-position
switch from the half-throttle position to the motor OFF
position. This switch also appears on the screen.
Move to the »Servo display« to check that the sys-
tem works correctly, and "experiment" with the various
delay times available in the right-hand column until
the system works exactly as you wish.
