Instructions ROXXY BL-Control S-BEC, # 1-01425 (06.04.2020 LA) • Errors and omissions excepted! •
MULTIPLEX
Connecting the three-core lead (UNI connector system) to
the receiver
Connect the three-core receiver lead (attached to
the speed controller) to the receiver input socket used for motor
speed control:
- With MULTIPLEX RC systems: channel 4 = throttle / motor
- With HiTEC RC systems: channel 3 = throttle / motor
Pin assignment
Do not connect a separate receiver battery to the receiver, as
the controller supplies current to the receiver and servos via the
S-BEC circuit. Disable the S-BEC system if necessary (
7.).
5. USING THE UNIT FOR THE FIRST TIME
By default, this speed controllers are set up for use with LiPo.
1. Using the ROXXY BL-Control S-BEC
the first time
1.1 Programmable RC
system
set servo travel for
throttle / motor to
100% in both
directions
1.2 Move transmitter
throttle stick (and trim,
if present) to the motor
OFF position
1.3 Transmitter ON
1.4 Connect a fully-
charged flight battery
⇒ Rising sequence of tones
⇒
In LiPo mode the number of
beeps indicates the detection
of a LiPo battery with X cells
(in NiXX mode the following
signals are emitted immediately)
⇒ Two rising tone sequences
⇒ Controller is ready for use
! Note:
Programmable parameters
If you wish to change one of the programmable parameters,
please refer to the Programming section ( 6.).
Start-up protection
The ROXXY BL-Control S-BEC speed controller are only armed
when the throttle stick is moved to the motor OFF position, and
when the audible “ready” indication has been emitted.
Always carry out a range check
Every time you wish to fly, carry out a range check with the RC
system switched on. Check in particular that radio range is not
diminished at full-throttle and half-throttle, and that no
interference occurs. Watch the servos in the model: if they jitter
or carry out random movements, this indicates an interference
problem which must be solved.
6. PROGRAMMING
Programming the ROXXY BL-Control S-BEC speed controller
could hardly be simpler; it is carried out using the transmitter
throttle stick or the MULTIPLEX MULTImate # 8 2094.
Beeps indicate the status of programming when using the
transmitter stick, and also confirm any changes. The procedure
runs through all variable parameters step by step. You select the
desired programming option by moving the throttle stick either to
the full-throttle or motor OFF position. Returning the stick to
centre takes you on to the next programmable parameter.
Activate programming mode
0.1
Flight battery disconnected
Stick to full-throttle position
Transmitter ON
0.2
Connect fully-charged flight
battery
⇒ Rising tone sequence
⇒ In LiPo mode:
Indicates detected LiPo
cell count
⇒ in NiXX mode the
following signal is emitted
immediately
Stick to full-throttle position
0.5
Stick to centre position
sounds four times: the
controller is now in
programming mode
1.
Select battery mode
(single beep, continuously repeated)
1.1
Automatic low-voltage cut-
off for LiPo batteries*
→ stick to full-throttle
position
OR:
For NiXX batteries
→ stick to motor OFF
⇒ Long tone
(confirmation signal)
1.2
Stick to centre position
2.
Select brake mode
(double beep, continuously repeated)
2.1
For brake ON*
→ stick to full-throttle
position
OR:
For brake OFF
→ stick to motor OFF
position
⇒ Confirmation signal
emitted
3.
Select direction of rotation
(triple beep, continuously repeated)
3.1
For reverse rotation
→ stick to full-throttle
position
OR:
For standard rotation*
→ stick to motor OFF
position
⇒ Confirmation signal
emitted
4.
Select motor cut-off type
(quadruple beep, continuously repeated)
4.1
For motor cut
(hard stop)
→ stick to full-
throttle position
OR:
For power
reduction *
⇒ Confirmation signal emitted
LiPo batteries:
Motor off at 3.0 V / cell
NiXX batteries:
Motor off at 6.0 V!
LiPo batteries:
Motor speed is reduced at 3.2 V /
