the physical control's course of travel by the touch of
a key. The switching action can be correlated to the
physical control's travel direction by software.
Of course control switches can also be freely com-
bined with the aforementioned physical switches to
solve even more complex problems.
There is a series of instructive examples which make
this programming child's play. Learn about this by tak-
ing advantage of the programming examples begin-
ning on page 268.
Logical switches
These functions permit two switches, control switches
and/or logical switches or any combination of these to
be combined with one another to create logical "AND"
and "OR" functionality. A total of 8 logical switches,
"L1 ... L8" can be programmed, see page 138.
Fixed switches FXI and FX
This type of switch turns a function, e. g. a timer, per-
manently on (closed fixed switch) or off (open fixed
switch) or they can provide a fixed input signal for a
control function, e. g. FXI = + 100 % and FX = -100 %.
For example, in flight phase programming, these fixed
switches can be used to switch a servo or speed con-
troller between two settings.
