Very Important - ROBBE Arcus E 2.2 ARF Notice De Montage

Specification - 20 A speed controller:
Continuous current: 20 A
Peak current: 25 A (max. 10 sec.)
BEC mode: Linear
BEC output: 5V / 2A
Cell count, LiPo: 2 - 3
Cell count, NiMH: 5 - 9
Low voltage protection: yes
Dimensions (speed controller): 42 x 25 x 8 mm
Weight: 18 g
Caution: the speed controller is not protected against rever-
se polarity. Connecting a battery to the controller's terminals
with reversed polarity will instantly ruin the unit.
VERY IMPORTANT: since different transmitters feature dif-
ferent throttle settings, we strongly advise you to use the
"Throttle range set-up function" to calibrate the throttle range.
Building and Operating Instructions - Arcus E 2.2 ARF
Setting the Full-Throttle and Stop positions:
(if the transmitter is new, the throttle range should always be
calibrated)
Switch transmitter on, move throttle stick to full-throttle posi-
tion.
Connect battery to speed controller.
You will hear the special beep sequence "123". This means
that the battery voltage is in the green zone.
This is followed by two longer beeps which confirm that the
controller has correctly read in the upper limit of the throttle
range.
The throttle stick must be moved to your preferred Stop po-
sition with two seconds; this is confirmed with a long beep.
This set-up procedure is concluded with an audible signal
which indicates the brake setting.
(1 x short beep = brake off;
2 x short beep = brake on).
The speed controller is now ready for use.
NOTE:
If you do not move the throttle stick during the set-up phase,
the motor will not run. In this case you must repeat the pro-
cedure.
Using the controller for the first time:
Move the throttle stick to the Stop position, then switch the
transmitter on.
Connect the flight battery to the speed controller: you will
hear the special sound sequence "123", followed by a longer
beep and the selected brake setting.
The speed controller is now ready for use.
Protective functions
1. Start-up guard: if the motor does not start within two se-
conds of the throttle command, the speed controller swit-
ches off the output voltage. If this should happen, you
MUST move the throttle stick fully back before the motor
will start. Failure to start may be due to any of the following
reasons: the connection between speed controller and
motor is intermittent; the propeller or the motor is jammed;
the gearbox is damaged, etc.
2. Overheating guard: if the controller's temperature rises
above 110°C, the unit reduces the output voltage.
3. Throttle signal failure protection: if the throttle signal is
absent for one second, the controller reduces the output
voltage. If a further failure occurs for two seconds, the con-
troller switches off the output voltage completely.
Description of functions
The speed controller is set up at the factory to suit the Arcus
E 2.2.
