The switches to operate the Snap-Roll program must
be connected to socket 6 and/or 7 of the transmitter
board. This code allows the programming of aileron,
elevator and rudder positions, plus the pre-setting of
the throttle position. Two Snap-Roll programs are
available, i.e. Snap-Roll to left and right. To control
this function, momentary switches, part No. 4160.11,
4160.44 or kick-switch M4144, are needed to select
the Snap-Roll program “SR…”, and to turn off the
function immediately the switch is released.
The both programs differ as shown in the following
tables, The final program to be activated is always
indicated in the display.
Switch Display Function Ch
Socket 6 SR1 Throttle 1
SR2 Aileron 2
SR3 Elevator 3
SR4 Rudder 4
Socket 7 SRT Throttle 1
SRA Aileron 2
SRE Elevator 3
SRR Rudder 4
Note:
If two separate momentary switches are used, and both are turned
on together, the one connected to socket 7 has precedence.
Simultaneous activation of the Automatic Landing (code 22) using
switch 5, the Snap-Roll program will be inactive underneath the
switch point of the Automatic Landing
Consecutive presses of the CH SEL button moves
through the channels “SR2” through “SR4” and/or
“SRA, “SRE”, and “SRR”. The three channels can be
set independent of the position of switches 6 and 7,
or turned off using the CLEAR button. The first of the
codes “SR1” and/or “SRT” for the throttle control is
actually the fourth code that appears. The function
selection is changed by the CH SEL button, with the
CLEAR button cancelling a setting.
Now the servo setting for each sub-code “SR…” can
be set using the INC and/or DEC buttons in the
range 0 … ±125%
Momentary operation of switch 7 changes the
display between "SRA", "SRE", "SRR", "SRT".
The normal Dual-Rate (D/R) and Exponential
functions for channels channel 4 (rudder), see page
20, can be linked to the throttle control stick to
automatically switch between the two settings at
about 70% of full throttle.
Example:
0 … 70% throttle Rudder travel increased to
125%, with linear motion
(“LN”).
70% … 100% throttle Rudder travel decreased to
40% and exponential set to
50%.
The auto-coupling function will only operate if the
external switch at connection 2 is turned off.
In the D/R / Exponential setting, the selection for
rudder (channel 4) below 70% throttle travel is
indicated by “ch4”, with above 70% being shown by
“CH4”.
With the auto-coupling disabled, i.e. AT4 = "OF", the
D/R and Exponential for the rudder uses the normal
switching, as described on page 20
or
With the "AT4" function activated, the external D/R /
Exponential switch (connection 2) must be in the off
position for the auto-coupling to function. The
desired values are set using INC & DEC .
Note
:
The auto-coupling affects control function 4 in
accordance with the block diagram on page 52. Thus
to the left of the output point for mixers, it can
operate other control paths using the freely
programmable mixers A, B and C, and the same
from the right of the input point for mixers. For
example mix "A47" and a setting of 100% would give
similar auto-coupling effect to control paths 4 and 7.
