**
LX Zeus has a connection for an external speed command switch, which is
wired to
vario unit. Using
an external switch it is possible to switch between SC and Vario manually. Setting the
SC Switch
to
ON
means that closing of the switch will cause SC mode, and setting
SC INPUT
to
OFF
means that closing
the switch will select Vario mode. There is a third option by setting SC INPUT to
Toggle
and connecting
a push button, now each press will toggle between SC and Vario (obligatory setting when using the LX
Remote).

LX Zeus has the capability to offer variometer total energy compensation in two
ways. Selection of compensation method is done after selection of the % figure.
000% means total energy compensation when
using a TE
tube. When using this
solution the unit does not process compensation this depends entirely
on the TE tube and its installation. After an input of a percentage which is other than zerothe special
software routines will be activated and will provide an electronic
compensation process. The default value is 100% but this can be varied following
a test flight.
The TE compensation can be fine tuned during flight with the following procedure. It is essential that this
is only done in smooth air; it is not possible to tune the TE accurately when it is thermic.
•
select 100 % and default TEF
•
accelerate up to approximately 160 km/h (75 kts) and keep the speed stable for a few seconds
•
gently reduce the speed to 80 km/h (45 kts)
Observe the vario indicator during the manoeuvre. At 160 km/h (75 Knots) the vario will indicate about –2
m/s
(-4kts). During the speed reduction the vario should move towards zero and should never exceed zero
(slightly positive indications are acceptable). If the vario shows a climb, then the compensation is too low,
increase the TE%; and vice versa. Repeat this procedure and make further adjustments if necessary.
Note!
Electronic and pneumatic TE compensation requires
different connection of tubes.
