MULTIcont
15. S-BEC = SWITCHING BEC
MULTIcont MSB EXPERT speed controllers are equipped with a
high-performance switching regulator BEC system: the receiver
and servos are fed power from the flight battery via the regulator;
A separate receiver battery is not required if a socket for a back-
up battery is not present.
! If a back-up battery socket is present, the model must not be
flown without a back-up battery.
Never connect a separate receiver battery!
Please note that the MULTIcont MSB EXPERT speed
controller's S-BEC power supply can only deliver a limited current
to the receiving system in the model:
The actual current drawn by a servo varies according to its
performance, the frequency of commands and – in particular –
the freedom of movement of the control surface linkages (!). This
means that it is essential to measure the current drain of the
servos in the model before the first flight, and at regular intervals
thereafter.
If you have no means of measuring the S-BEC current: carry out
a test-run on the ground: operate the servos in a "normal" way
(similar to flying the model) until the low-voltage cut-off is
triggered (i.e. battery flat). At this point the speed controller
should be no more than warm to the touch, and the servos must
work properly all the time, without ever threatening to fail or move
erratically.
! Note: disabling the S-BEC system
The S-BEC system must be disabled, and a separate receiver
battery must be used instead, if:
•
the model carries more servos, or servos with a higher
current drain, than is permissible (
•
problems are evident during the test-run
Disabling the S-BEC system: locate the UNI connector attached
to the three-core lead. Use a pointed instrument to raise the
plastic lug of the red wire (+), and withdraw the red wire from the
plastic housing. Insulate the bare metal parts with a heat-shrink
sleeve.
! Note:
In principle several MULTIcont MSB EXPERT speed controllers
with their BEC systems can be connected to a receiver in parallel.
The only point to note here is that the set BEC voltage should be
the same on all the speed controllers connected to the receiver;
the BEC systems will only supply current to the receiver
simultaneously if this is the case. If different voltages are set, then
the BEC system with the highest voltage is the only one which
supplies current to the receiver.
16. O
PERATING WITH A
MULTIcont MSB EXPERT speed controllers (80 A and higher)
are operated with a back-up battery to support the BEC power
supply. If the speed controller's voltage should collapse, then the
supplementary battery acts as back-up power supply to the
receiver and servos.
The back-up battery should consist of a four-cell or five-cell NiXX
or 2S LiPo pack, connected to the UNI socket of the speed
controller marked SAFETY-BATT.
!
Caution: if the voltage of the back-up battery is higher than
the BEC voltage set on the receiver, then the voltage passed to
the receiver will be the higher one. You should therefore always
ensure that both the receiver and the servos are approved for use
with the voltage of the back-up battery and the BEC voltage set
on the speed controller.
