GRAUPNER mz-24 Pro Programming Manual page 112

• SUMD
A HoTT receiver configured as SUMD as described
earlier always generates a digital aggregate signal
from the control signals of a selectable number of
its controls channels, see more about on in the
SUMO section, and forwards this to servo connec-
tion 8 in the GR-16 and GR-24 receivers.
At the time this manual was revised, this type of
signal was being used by several of the latest elec-
tronic applications of flybarless systems, power
supplies, etc.
Notice
You therefore need to consult your setting in-
structions for the attached device since oth-
erwise you may make it impossible to fly the
model.
After confirming "SUMD" by touching the
button at the bottom right in the display, the active
value field switches to the right for selecting one
of the three possible receiver reactions in case of
a loss of reception (fail safe):
