The following pictures show how to set the throttle range with a
Futaba
TM
transmitter.
A) Switch off the ESC, turn on the transmitter,
set the “EPA/ATV” value of throttle channel to
“100%”, and disable the “ABS” brake function
of your transmitter if it does has this function.
B) Hold the “SET” key and then switch on the
ESC, when the red LED begins to flash,
release the key immediately. (Please refer to
the picture on the right side) (
*
Note2
)
C) Set 3 points according to
the steps shown in the
picture on the right side.
1) Neutral point
2) End point of forward
direction
3) End point of backward
direction
D) When the process of
calibration is finished, the
motor can be started after
3 seconds.
*Note2: If you don’t release the “SET”
key after the red LED begins to flash,
the ESC will enter the program mode,
in such a case, please switch off the
ESC and re-calibrate the throttle range
again from step A to step D.
If you are not using a gun-style
transmitter, please refer to the
right picture to set the throttle range.
3. The LED Status
In normal use, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
a)
The red LED lights when the boat is run forward or backward.
b)
The green LED lights when the throttle stick is moved to the top point (end point) of the forward zone or backward
zone.
c)
The red LED flashed quickly when the boat is braking.
d)
If the ESC is over heat, the output power will be gradually cut-off to protect the ESC, in such a case, the Green
LED will flash in such a way: “Flashes-----Flashes-----Flashes-----”
Alert Tones
1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if it is out of the
normal range, such an alert tone will be emitted: “beep-beep-, beep-beep-, beep-beep-” (There is 1 second time
interval between every “beep-beep-” tone).
2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will
be emitted: “beep-, beep-, beep-” (There is 2 seconds time interval between every “beep-” tone).
Protection Function
1. Low voltage cut-off protection: If the voltage of a lithium battery pack is lower than the threshold for 2 seconds,
the ESC will cut of the output power. Please note that the ESC cannot be restarted if the voltage of each lithium
cell is lower than 3.5V.
For NiMH/NiCd battery packs, if the voltage of the whole NiMh/NiCd battery pack is higher than 9.0V but lower
than 12V, it will be considered as a 3 cells lithium battery pack; If it is lower than 9.0V, it will be considered as a 2
cells lithium battery pack. For example, if the NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, so
it will be considered as a 2 cells lithium battery pack, and the low-voltage cut-off threshold for this NiMH battery
pack is 2.6*2=5.2V.
2. Over-heat
protection: When the temperature of the ESC is over a special value for 5 seconds, the ESC will
gradually cut off the output power.
3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.
