VERY IMPORTANT:
since different transmitters feature different throttle
settings, we strongly advise you to use the "Throttle range set-up function" to
calibrate the throttle range.
Caution: this controller is not protected against reversed polarity.
Connecting a battery to the controller's terminals with reversed polarity
will instantly destroy the unit.
If you prefer to use a separate receiver battery instead of the
BEC system, you must withdraw the red wire from the receiver
lead attached to the controller, and insulate the bare end to avoid short-circuits.
Using the controller for the first time:
Move the throttle stick to the Stop position, then switch the transmitter on.
Connect the flight battery to the speed controller, special beep sequence "123".
You will hear the following according to the selected battery type:
Beep, beep, beep, beep for detected 4S LiPo battery. At the end a long beep
---- is emitted: the speed controller is now ready for use.
Move throttle stick forward: motor starts.
Setting the full-throttle and stop positions:
(if the transmitter is new, the throttle range should always be re-calibrated)
Switch transmitter on, move throttle stick to full-throttle position.
Connect battery to speed controller.
"Beep-Beep" sequence sounds, indicating that the upper throttle position
stop has been correctly confirmed. Move the throttle stick to the desired Stop
position.
"Beep-Beep" sequence sounds again, indicating that the Stop position has been
correctly confirmed. Finally a long beep will sound.------. The speed controller is now
ready for use.
Note:
When programming the Stop position, you will hear a series of short
sequential beeps heard followed by 2 short beeps if the throttle stick is at the
wrong end of its travel.
Protective functions
1. Start-up guard: if the motor does not start within two seconds of the
throttle command, the speed controller switches off the output voltage. If
this should happen, you MUST move the throttle stick fully back before
the motor will start. Failure to start may be due to the following reasons:
intermittent connection between speed controller and motor; the propeller
or the motor is jammed; the gearbox is damaged, etc.
2. Overheating protection: if the controller's temperature rises above 110°C,
the unit reduces the output voltage.
3. Throttle signal failure protection: if the throttle signal is absent for one
second, the controller reduces the output voltage. If a further failure occurs
for two seconds, the controller switches off the output voltage completely.
