Freely Programmable Mixers - GRAUPNER mc-16 Programming Manual

Freely Programmable
Mixer
Free Programmable Mixer
(access via Set-Up Menu)
Additional to the pre-programmed mixer functions
contained in the helicopter program are two freely
selectable mixers, which are characterized by the
letters A and B and the number of the input function
and the output channel. The lower display line will
show either the mix portion and direction, or "OF" if
the mixer is switched off using the associated
external switch.
Setting example for mixer "A"
1. Channel Selection.
Firstly the button is pressed until in the
CH SEL
upper display line "Ach" appears. Using the
the number of the input channel 1 to 8 is entered (left
digit), with the key the channel of the receiver
DEC
output 1 to 8 (right digit). Pressing the
performs a reset and sets input function and output
channel to "1", mix proportion and offset to 0% and
the mixer switch on "ON".
2. Allocation of a mixer switch.
Pressing the button changes the display to
CH SEL
"ASW" (A-Switch). This is where it is specified
whether the mixer remains constantly switched on,
(display "ON" is shown), or whether it is turned on
and off by an assigned external switch. The selection
is made with the or keys. The lower line
INC DEC
of the display shows the transmitter board socket for
the external switch allocated:
Mixer Transmitter Socket
A 7
B 6
Note:
Switch 6 also simultaneously switches the mixers for
static and dynamic torque compensation, and switch
7 the automatic gyro gain reduction.

3. Setting mix proportion and mix direction.
By pressing the
CH SEL
adjusting the mix proportion and direction appears.
Using the and/or
INC
proportion can be set between 0 and ±125%,
symmetrically to the neutral point (pressing
resets the value to 0%). If an external switch was
assigned, the mixer can be switched off now and the
display will show "OF".
4. Specify the mixer neutral point (offset setting).
If is pressed again, you arrives at the offset
CH SEL
key setting. To set the offset place the control stick in the
INC
desired position and press the
offset is indicated in the display. (value range:
button approx. -85 to +85).
CLEAR
If an external switch has been assigned and is
switched off, the display shows "OF".
(If you want to change the stored offset, the mixer
offset setting is re-entered and the new position
stored as above).
Thus the programming of mixer A is completed. The
setting of mixer B is completed in the same way.
Note:
In the helicopter programs control function 6 cannot
be used as input signal for a mixer as it does not
possess an "output point for mixers" (see the block
diagram on page 62). The signal from this channel
only affects receiver output 6 directly and servo
travel is limited to 25% of the normal value.
Dependent on the type of swashplate (Swash Mixer)
certain control paths are linked with one another (as
with all finished mixers). For example, the basic
standard mixer "N" links control function 1 with
channel 6. The mix proportions of a finished and a
freely programmable mixer can be overlaid in such a
way that a servo movement is changed.
