The ESC will not provide any power to the motor, if the throttle
stick is anywhere higher then zero throttle when the main battery
is plugged in. To arm the esc ready for use you, You must move
the throttle stick to zero then disconnect and re connected the
battery.
Always power your radio transmitter before powering up the
receiver and/or the ESC. Some receivers with failsafe features or
Spektrum receiver units that are not bound on receiver power up
are entirely capable of causing the arming sequence to occur and
command the ESC to drive the motor. Always keep the aircraft
restrained and clear of body parts when the ESC is powered.
If your ESC cannot sense any radio signal it will beep the motor
and flash orange on the LED continuously
3.0 Scorpion SBEC features
ALL of the Scorpion 26V SBEC programming features are
available though the use of the ESC programming card
included with your ESC. So there is NO need to purchase any
other cables or cards to allow you to program your ESC
properly
Scorpion ESC’s come with default or factory settings which
are recommended for most applications. Programming
options can be changed at the discretion of the user. See
section 6.0 for programming instructions
Features:
Safe Power up
To arm the controller, the throttle must be
held in the “Brake/Zero” position (all the way
down). If throttle is not at zero at startup, the ESC
will not provide any power to the motor regardless
of where the throttle stick is positioned when first
powered up.
Loss of signal
(fail safe)
The Scorpion will stop the motor as a safety
feature when the throttle signal is lost or
corrupt for 3 seconds. If a signal is regained the
user will have instant control again.
LED
The LED is used for programming/startup
confirmation of your scorpion esc. Once armed
the LED can be set to give an indication of low
battery conditions
Low Voltage Cutoff
You can choose for your ESC to stop or reduce
power when the input battery voltage drops to a
preset/programmed cutoff voltage.
Current Limiting
Amp output limit, the output is rated at 10% over
the rated Amp. At approximately 10% over the
rated Amps it will automatically limit the output to
the motor, as long as the motor is not rated too
much over the ESC spec limits, this safety
mechanism will prevent a over load to the ESC but
if you install a motor for example rated at 100
amp on a ESC that are rated for only 60Amp, this
mechanism will not work properly due to the
instant surge of power demand from the motor, it
may shutdown too early or simply fry the ESC, the
only solution to this is to never use a Motor that
has a rating bigger then the ESC, don’t even think
you can use it if you run the motor at a slower
RPM or load, it will not work!!
Thermal Protection
At 95 degree C, the ESC will slowdown the power
output to the motor by 50% ( the on board LED
will flash red), to re initiate full throttle you need
to move the throttle stick to idle position and then
the ESC will resume normal output once you
throttle up again. If your ESC is over 60deg on
startup it will not arm red LED will flash and a DI
DI DI sound will be played.
Brake
Stops rotation of the motor when the
throttle signal is moved to the lowest
position.
Throttle
Airplane, Car and Heli modes come pre
programmed and can be selected by the user
Electronic timing
Manual settings that may improve the efficiency of
the system for some motors are available. The
standard Scorpion setting is to automatically
detect and adjust for the motor it is driving.
4.0 Initial setup
You MUST perform throttle range setup before the first use of
the ESC. Remove propeller/pinion from motor while
performing initial throttle range setup.
4.1
Throttle range setup (full throttle and stop)
4.2
Turn on transmitter and set throttle to maximum
position
4.3
Connect battery to ESC. After approximately 2
seconds, the LED flashes rapidly, then 1 second after
you will hear 2 beeps from the motor confirming the
maximum throttle position has been set. (If at this
time, you leave the throttle stick at maximum
position for over 10 seconds, the ESC will reset itself
to Factory default throttle setting)
4.4
Move throttle to minimum position within 10 seconds
and hold throttle at minimum position, the LED
flashes slowly for 1 second. Then you will hear 2
beeps (1 KHZ tone) indicating minimum throttle
position is set and confirmed. You only need to do
this once as throttle range will be stored in the
memory of the speed controller. You can reset the
throttle range by performing steps 1.1 to 1.3 again
5.0 Connecting your Scorpion
SBEC to the programming card
Your Scorpion SBEC is programmed using the Infrared (IR)
Program card and Receiver included with this ESC.
First you must connect your IR Receiver to your ESC
Ensure the brown wire from your esc is facing outwards
5.1
Once you have plugged in the IR Receiver push the
switch across to IRS.
5.2
Now connect a battery to the ESC. Your motor will emit 3
beeps and the LED will flash 3 times red.
5.3
Your IR Receiver is now ready to receive a signal from
the program card.
please note that IR will be interfered in direct sunlight so to
program your model we suggest doing it indoors in the shade out
of direct sunlight
before flying you will need to place the switch back to PPM mode
