These operating instructions are an integral part of this
product. They contain important information and safety
notes, and should therefore be kept in a safe place at all
times. Be sure to pass them on to the new owner if you ever
dispose of the product.
1. S AFETY N OTES
!
Read the instructions before using the controller
!
Avoid heat build-up
Provide unobstructed air circulation round the controller
!
Do not connect the flight battery with reversed polarity
Connecting the battery leads with reversed polarity will
instantly wreck the controller
For this reason:
• red wire to the POSITIVE terminal (+)
• black wire to the NEGATIVE terminal (-)
!
When soldering or working on the motor or controller
Always disconnect the battery (short-circuit / injury hazard)
!
When testing and running the power system
Do not run the motor while holding it in your hand; always
secure the model firmly. Check that there is adequate space
for the propeller to rotate. Remove all objects from the area
around the propeller which could be sucked in or blown away
(clothing, paper etc.). Never stand in the rotational plane of
the propeller (injury hazard).
2. S PECIFICATION
MULTIcont BL15 BL-15
Order No.: # 7 2265
max. continuous current: 15 A
Pulse frequency: 8 kHz or 16 kHz (adjustable)
Receiver power supply
max. 3S LiPo or
9 NiXX cells
BEC voltage: 5.0 V
BEC current: max. 2.0 A
Dimensions in mm (approx.): 40x25x9
Weight incl. leads (approx): ca 22 g
Maximum number of servos usable with MULTIcont BL-15
controllers in BEC mode**
MULTIcont BL-15
Maximum number of micro / standard servos*: 4
* MULTIPLEX Nano-S or Tiny-S servo types.
** If the number of servos in the model exceeds the stated
maximum, it is essential to disable the BEC system and use a
separate receiver battery (
7.).
3. S PECIAL F EATURES
MULTIPLEX MULTIcont BL-15 controller offers an excellent
range of additional features:
•
numerous programmable parameters
- low-voltage cut-off for: LiPo and NiXX batteries
- brake: ON or OFF
- motor reverse: on or off
- motor cut-off type: motor power reduction or motor cut
- motor start behaviour: soft or standard
- timing: automatic or manual (7 degrees or 22 - 30 degrees)
- pulse frequency: 8 kHz or 16 kHz
- model type: fixed-wing or helicopter (governor mode)
These parameters are programmable using the
transmitter throttle stick.
!
But not with the MULTIPLEX MULTImate # 8 2094 or PC.
•
With BEC (Battery Eliminator Circuit)
receiver power supply from the flight battery.
•
Start-up safety system prevents the motor bursting into life
when the flight battery is connected
•
Motor cut if major interference occurs or the transmitter signal
fails
•
Automatic low voltage cut-off with re-start facility (Reset
function) for LiPo and NiXX cells
4. W IRING
!
Note: if you wish to use a different connector system for
connecting a MULTIcont BL-15 speed controller to your
motor and / or battery, please note the following infor-
mation:
Soldering requires some care, as the quality of the joints is
crucial to the reliability of the power system:
•
Use electronic-grade solder for all soldered joints
•
Do not use acid-based solder flux
•
Parts to be soldered must be hot enough (the solder must
flow), but must not be overheated (damage to components)
•
If you are unsure, ask a modeller with experience in soldering
to help you
•
Carefully insulate all solder joints and bare wires (e.g. using
heat-shrink sleeving)
Attaching the battery connectors
The battery connectors have to be attached to the two wires (red
= +, black = -). Keep the wires as short as possible. If necessary,
cut the battery leads to the required length. Fit a piece of heat-
shrink sleeve on each wire, and shrink the sleeve over the
soldered joint.
Take great care to maintain correct polarity when soldering the
battery connectors to the leads. Reversed polarity inevitably and
invariably wrecks the controller.
Connecting the speed controller to the motor
The motor is connected to the three wires which exit one end of
the controller. Solder sockets to the wires which match the motor
connectors, and insulate each soldered joint with a separate
heat-shrink sleeve. Keep the leads as short as possible.
If you need to reverse the direction of rotation of the motor,
simply swap over two of the three wires leading to the motor;
alternatively change the direction by programming (
6.3.).
