ROGRAMMING
Programming the MULTIcont BL-17 is very simple, and is
carried out using the throttle stick. Audible beeps indicate the
status of the programming procedure, and confirm any changes
that you make. The process cycles through all the variable
parameters step by step. Initially the throttle stick should be left
at the centre position. The desired programming options are
selected by moving the stick either to the full-throttle or the
motor OFF position. Moving the stick back to centre confirms
your selection, and moves on to the next parameter.
The software of the MULTIcont BL-17 has been designed to
make it impossible to switch to programming mode accidentally.
This initially gives the impression that it takes a very long time to
switch to programming mode, but this is intentional: for your own
safety it is essential that you cannot enter programming mode by
mistake when you are preparing to fly, or actually flying.
1. Activating programming mode
1.1 Stick to full-throttle position
1.2 Connect battery
1.3 Stick to centre position
1.4 Stick to full-throttle position
1.5 Stick to centre position
2. Select battery mode (single beep)
2.1 for Li-Po
stick to full-throttle position
or
for NiCd / NiMH
stick to motor OFF position
2.2 Stick to centre position.
3. Select brake mode (double beep)
3.1 for brake ON
stick to full-throttle position
or
for brake OFF
stick to motor OFF position
3.2 Stick to centre position.
4. Select direction of rotation (triple beep)
4.1 for default direction
stick to full-throttle position
or
for reverse direction
stick to motor OFF position
When the last programming step is finished, the controller
terminates programming mode. Now disconnect the flight battery
without moving the stick again.
However, it does no harm to move the stick back to the centre
position. If you do this, the motor emits three single beeps, and
you can disconnect the battery.
Move the throttle stick to the idle position and re-connect the
flight battery. The speed controller is now ready for use with the
newly set parameters.

7. BEC = B
ATTERY
BEC means: the controller supplies electrical current to the
receiver and servos from the flight battery. For this reason: do
not use a separate receiver battery.
! Note:
Please note that the MULTIcont BL-17's BEC circuit is only
capable of supplying a peak of 1.5 A of current for the model's
airborne receiving system.
NiCd / NiMH cell count
Li-Po cell count
Standard (micro) servos
High-torque servos
The current drain varies according to the power of the servos,
the frequency of control commands and the stiffness of the
control surface linkages (!).
If you do not have any means of measuring the BEC current, we
recommend that you carry out a ground-check by operating the
servos continuously until the battery is flat (low-voltage cut-off
triggered). The controller must not become more than warm to
the touch during this test, and the servos must respond correctly
to stick movements without any sign of failure.
If your model carries more servos than specified, or you wish to
use a flight battery with more than 10 cells, the BEC circuit must
be disabled, and a separate receiver battery installed.
The BEC system is disabled by disconnecting the red (+) wire in
the lead. Withdraw the red positive wire from the plug housing,
and insulate the contact with a heat-shrink sleeve.
Low-voltage cut-off
The MULTIcont BL-17's low-voltage cut-off circuit switches off
the motor in the model when the flight battery is discharged. This
ensures that the battery maintains adequate energy reserves for
the BEC system, so that a safe landing can be carried out. It
also ensures that Li-Po batteries are not discharged too far.
Another indication that the flight battery is almost discharged is
declining motor power (propeller speed). When you notice this, it
is time to prepare for the landing approach.
The controller automatically switches off the motor when the
NiCd / NiMH flight battery voltage falls to 5 Volts; in Li-Po mode
the bottom limit is 6 V (two cells) or 9 V (three cells). If the
battery reaches this trigger voltage and the controller switches
off the motor, you can switch it on again briefly (to enable you to
reach the landing area) by moving the throttle stick to the idle /
motor OFF position for a moment, then advancing it again
(Reset function). This should only be carried out once or twice.

AULT FINDING

FAULT ELIMINATION

Everything is connected correctly, the BEC system works,
the servos operate, but the throttle function does not work.
The most likely problem is that you did not wait the minimum
four seconds in the motor OFF position after connecting the
battery, so the controller is not "armed".
Remedy: move the throttle stick (and trim!) back to motor OFF
and leave it there for at least four seconds.
You should also check servo travel at the transmitter: it must be
set to at least 100%. If the motor still does not respond to the
throttle stick, you must reverse the direction of the throttle
channel control at the transmitter.
Every time you apply full-throttle, the controller switches off
the motor after a few seconds. This happens in particular
when you connect a freshly charged battery.
