Safety Notes; Special Features - Multiplex MULTIcont BL-20 SD Instrucciones

! 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.

AFETY 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)
!
Caution: since different makes of transmitter use
different throttle travels, always start by programming
the throttle travel. (
! 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).

PECIAL EATURES
MULTIPLEX MULTIcont BL-20 SD / SD-L speed controllers
include a series of interesting features:
•
numerous programmable parameters
- Low-voltage cut-off for: LiPo or NiXX batteries
- Brake: ON or OFF
- Motor cut-off mode: motor power reduction, or
motor stop
- Motor start mode: standard, soft and super-soft.
- Timing: low, medium, high
•
Safety start system prevents motor starting accidentally when
battery is connected
•
Motor cut-off if serious radio interference occurs, or trans-
mitter signal fails: power reduction after one second of inter-
ference, motor off if interference longer than three seconds.
•
Start-up guard: if the motor cannot run within two seconds,
the controller switches the motor off. To re-start the motor the
throttle stick must first be moved to the "Idle" position.
•
Temperature guard: if the controller overheats, it reduces
power to the motor.
Caution: The BL-20 SD / SD-L can not be programmed with
the MULTImate!

Note: if you wish to use a different connector system for
connecting a MULTIcont BL-20 SD / SD-L 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.
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
