230 Detail program description - Telemetry
L.R-VOLT Lowest operating voltage of the
receiver since it was last turned on, in
volts
SENSOR1 Indicates values of optional telemetric
sensor 1, in volts and °C
SENSOR2 Indicates values of optional telemetric
sensor 2, in volts and °C
Signal quality (S-QUA)
The signal quality (S-QUA) is sent "live" over the
receiver's return channel to the transmitter and
indicates the signal strength in %.
Reception power (S-dbm)
Reception power (S-dbm) is indicated with negative
values, which means a value of zero is the maximum
value (= best reception) and the lower the values are,
the poorer the reception power! The range test before
operation, among other things, is important for this.
Note:
With negative numbers the evaluation of a number is
reversed: The higher the number following the minus
symbol, the lower the value is. Therefore, a reception
power of -80 dBm, for example , is poorer than one of
-70 dBm.
Perform the range test as described on page 80 and
88 before each fl ight and, in doing so, simulate all
servo movements which also take place during the
fl ight. The range must be at least 50 m on the ground
with the range test activated. At this distance, the
value shown under "S-dBm" in the "
RX DATAVIEW "
display may not be greater than -80 dBm in order to
guarantee safe operation. The model should never
be operated with a lower value (e.g. -85 dBm). Check
the installation of the receiver system and the position
of the antenna.
The reception power should not drop below -90 dBm
during operation. Otherwise, reduce the distance of the
model. Normally, however, the acoustic range warning
(peep tone interval 1 s) is triggered before this value is
reached in order to guarantee safe operation.
Signal strength (S-STR)
The signal strength (S-STR) is displayed in %. In
general, an acoustic range warning (peep tone
interval 1 s) is issued as soon as the receiver signal
becomes too week in the return channel. However,
since the transmitter has a signifi cantly higher
transmission power than the receiver, the model can
still be safely operated. For the sake of safety, the
distance to the model should be reduced until the
warning tone goes silent again.
Receiver temperature (R-TEM.)
Make sure the receiver remains within the permissible
temperature range during all fl ight conditions (ideally
between -10 and 55 °C).
The receiver temperature limit, at which a warning
is issued, can be adjusted in the sub-menu »
RX
SERVO TEST « under "ALARM TEMP+" (50 … 80 °C
and "ALARM TEMP-" (-20 … +10 °C). When the
value is under-run or over-run, an acoustic signal
sounds (continuous peep tone) and "
TEMP.E " will
appear at the top right of all "RX" receiver sub-menus.
Additionally, the parameter "
R-TEM " will be displayed
in inverse video on the » RX DATAVIEW « display
page.
Data packages (L PACK TIME)
Indicates the longest time span in ms in which data
packages are lost in the transmission from the
transmitter to the receiver. In practice, that is the
longest time span in which the remove control system
has entered into fail-safe mode.
Receiver operating voltage (R-VOLT)
Always check the operating voltage of the receiver.
Never operate or even start your model if the
operating voltage is too low.
The receiver low voltage warning can be adjusted
between 3.0 and 6.0 volts in "ALARM VOLT" of the
»
RX SERVO TEST « sub-menu. If this range is under-
run, an acoustic signal is sounded (repetitive double
peep tone (long/short)) and "
VOLT.E " will appear at
the top right of all » RX …« receiver sub-menus.| In
addition, the parameter " R-VOLT " will be displayed in
inverse video in the » RX DATAVIEW « sub-menu.
The current receiver battery voltage is also displayed
in the default display, see page 28.
Minimum receiver operating voltage (L.R-VOLT)
"L.R-VOLT" indicates the minimum operating voltage
of the receiver since the last time it was switched on.
If this voltage should deviate signifi cantly from the
current "R-VOLT" operating voltage, the receiver
battery may be too heavily encumbered by the
servos. The consequence is voltage drops. In this
case, use a more powerful voltage supply in order to
achieve maximum operational safety.
Sensor 1 + 2
Indicates the values of optional telemetric sensors
1and 2, if present, in volts and °C. A description of
these sensors can be found in the appendix.
