3.2.6 Servo test (RX SERVO TEST)

To switch to the Servo test display, press the ENTER button repeatedly until RX SERVO TEST appears on

the screen

Display-Anzeige Erläuterung Einstellungen

ALL MAX Maximum control surface travel position for all servos 1500 – 2000 usec

ALL Min Minimum control surface travel position for all servos 1000 – 1500 usec

TEST Test procedure START / STOP

ALARM VOLT Displays the set voltage at which the low voltage

warning signal is triggered

3.0 – 7.5 V

Factory setting 3.8 V

ALARM TEMP+ Displays the upper limit value at which the warning

signal is triggered

50 – 80° C

Factory setting 70°C

ALARM TEMP- Displays the lower limit value at which the warning

signal is triggered

-20 – +10° C

Factory setting -10°C

CH OUTPUT TYPE Channel sequence / Sum signal ONCE / SAME / SUMI /

SUMO / SUMD

Maximum control surface travel position (ALL MAX): this is where you set the maximum control surface

travel for the servo test

Minimum control surface travel position (ALL min): this is where you set the minimum control surface

travel for the servo test

Test procedure (TEST): START initiates the servo test process; STOP halts it again. You start and stop the

test by simultaneously pressing the INC / DEC buttons (dark background disappears)

Receiver low voltage warning (ALARM VOLT): monitors the receiver voltage, and can be set to any value

within the range 3.0 to 6.0 Volt. If the voltage falls to the threshold value, an audible signal is emitted (conti-

nuous beeping), and “VOLT.E” ﬂ ashes at top right in all the Smartbox’s receiver displays; at the same time

the parameter R-VOLT is displayed in inverse form in the receiver data display (RX DATAVIEW).

Receiver temperature monitor (ALARM TEMP +/-): monitors the receiver temperature. It is possible to

program both a lower limit value ALARM TEMP- (-20 – +10°C) and an upper limit value ALARM TEMP+

TEMP (50 – 80°C). If the receiver temperature rises above the maximum value or falls below the minimum,

the unit generates an audible warning (continuous beeping). At the same time all the Smartbox receiver

displays show a ﬂ ashing “TEMP.E” at top right, and the parameter R-TEM is shown in inverse form in the

receiver data display (RX DATAVIEW).

It is important that the temperature of your receiver always stays within the approved range under all ﬂ ight
