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
Negative pin (
−
) brown
Positive pin (+) red
Signal ( ) orange
Do not connect a separate receiver battery to the receiver,
as the controller supplies current to the receiver and servos
via the BEC circuit. Always keep to the maximum servo
count limit in BEC mode (
2.). Disable the BEC system if
necessary ( 7.).
5. U SING THE UNIT FOR THE FIRST TIME
By default, MULTIcont BL-15 speed controllers are set up for
use with LiPo batteries; the brake is ON.
1. Using the MULTIcont BL-15 controller for 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
MULTIcont BL-15 speed controllers 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. P ROGRAMMING
Programming the MULTIcont BL-15 speed controller could
hardly be simpler; it is carried out using the transmitter throttle
stick or - for even greater convenience - 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.
0. 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
⇒ Rising tone sequence
0.3 Stick to centre position ⇒ Rising tone sequence
0.4 Stick to full-throttle position ⇒ Rising tone sequence
0.5 Stick to centre position ⇒ Rising tone sequence
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
position
⇒ 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
2.2 Stick to centre position
