3. First steps, the unit in use
a) Connections
- First connect the three satellite receivers. All three receivers must be connected,
otherwise the system will not start. The purpose of this requirement is safety, as
it reveals sources of errors such as faulty connecting leads in good time. Any
faults which develop in flight have no effect, as reception is always adequate with
at least one satellite receiver.
- Connect the servos to the appropriate sockets; the function assignment is printed
on the
PowerBox
itself.
- Now connect the
SensorSwitch
to the appropriate socket on the unit, ensuring
that the ribbon cable faces up as shown. In models subject to severe vibration we
recommend that you secure the ribbon lead by at least one additional point to
avoid the connector working loose. If the connector were to fall out, it would have
no effect on the switched state of the
PowerBox
, but would prevent you switching
the system off.
- The optional ultra-bright external LEDs can now be connected to the unit. We
urge you to connect them and mount them in the fuselage side, as they enable
you to detect battery problems when the model is flying.
- The final step is to connect the batteries to the
PowerBox
’s integral MPX
connectors. We recommend the use of batteries or
1500mAh
or
2800mAh
capacity from
PowerBox Systems
. If you prefer to use other makes of battery, or
wish to make up your own packs, it is absolutely essential to maintain correct
polarity. Check twice rather than make a mistake! Connecting a battery with
reversed polarity will instantly ruin the voltage regulators. In order to minimise
power losses, the
Evolution Spektrum
does not feature reverse polarity
protection. The
+
(positive) indicator can be seen on the case cover.
