If a special tone “
” is emitted after 2 beep tones (“beep-beep-”), means the ESC has entered the program mode, it is
because the throttle channel of your transmitter is reversed, please set it correctly;
If the very rapid “beep-beep-, beep-beep-” tones is emitted, means the input voltage is too low or too high, please check your
battery’s voltage.
3. “
VERY IMPORTANT !
” Because different transmitter has different throttle range, we strongly suggest you using the “Throttle Range
Setting Function” to calibrate throttle range. Please read the instruction on page 4------“Throttle Range Setting”.
Alert Tone
1.
Input voltage is abnormal: The ESC begins to check the voltage when the battery pack is connected, if the voltage is not in the
acceptable range, such an alert tone will be emitted: “beep-beep-, beep-beep-,beep-beep-” (Every “beep-beep-” has a time interval of
about 1 second. )
2.
Throttle signal is abnormal: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-, beep-,
beep-”. (Every “beep-” has a time interval of about 2 seconds)
3.
Throttle stick is not in the bottom position: When the throttle stick is not in bottom (lowest) position, a very rapid alert tone will be
emitted: “beep-, beep-, beep-”. (Every “beep-” has a time interval of about 0.25 second.)
Protection Function
1.
Abnormal start up protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In
this case, the throttle stick
MUST
be moved to the bottom again to restart the motor. (Such a situation happens in the following cases:
The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)
2.
Over-heat protection: When the temperature of the ESC is over 110 Celsius degrees
,
the ESC will reduce the output power.
3.
Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further loss for 2 seconds
will cause its output to be cut-off completely.
Program Example
Setting “Start Mode” to “Super-Soft”, i.e. value #3 in the programmable item #5
Trouble Shooting
Trouble Possible
Reason
Action
After power on, motor does not work, no
sound is emitted
The connection between battery
pack and ESC is not correct
Check the power connection.
Replace the connector.
After power on, motor does not work,
such an alert tone is emitted:
“beep-beep-, beep-beep-,beep-beep-”
(Every “beep-beep-” has a time interval
of about 1 second)
Input voltage is abnormal, too high
or too low.
The balance charge connector is
not located properly in BDMP
adapter.
Check the voltage of battery pack
Check the connection of the balance charge
connector and the BDMP adapter.
After power on, motor does not work,
such an alert tone is emitted:
“beep-, beep-, beep- ”(Every “beep-” has
a time interval of about 2 seconds)
Throttle signal is irregular
Check the receiver and transmitter
Check the cable of throttle channel
After power on, motor does not work,
such an alert tone is emitted:
“beep-, beep-, beep-” (Every “beep-” has
a time interval of about 0.25 second)
The throttle stick is not in the
bottom (lowest) position
Move the throttle stick to bottom position
After power on, motor does not work, a
special tone “
” is emitted after 2
beep tone (beep-beep-)
Direction of the throttle channel is
reversed, so the ESC has entered
the program mode
Set the direction of throttle channel correctly
The motor runs in the opposite direction
The connection between ESC and
the motor need to be changed.
Swap any two wire connections between ESC and
motor
Throttle signal is lost
Check the receiver and transmitter
Check the cable of throttle channel
ESC has entered Low Voltage
Protection mode
Land RC model as soon as possible, and then
replace the battery pack
The motor stop running while in working
state
Some connections are not reliable
Check all the connections: battery pack connection,
throttle signal cable, motor connections, etc.
Random stop or restart or irregular
working state
There is strong electro-magnetic
interference in flying field.
Reset the ESC to resume normal operation. If the
function could not resume, you might need to move
to another area to fly.
1. Enter Program Mode
Switch on transmitter, move throttle stick to top position, connect battery pack to ESC, wait for 2 seconds, “beep-beep” tone should
be emitted. Then wait for another 5 seconds, special tone like “
” should be emitted, which means program mode is entered.
2. Select Programmable Items
Now you’ll hear 8 tones in a loop. When a long “beep------” tone is emitted, move throttle stick to bottom to enter the “Start Mode”
3. Set Item Value (Programmable Value)
“Beep-”, wait for 3 seconds; “Beep-beep-”, wait for another 3 seconds; then you’ll hear “beep-beep-beep”, move throttle stick to top
position, then a special tone “
” is emitted, now you have set the “Start Mode” item to the value of “Super-Soft”
4. Exit Program Mode
After the special tone “
”, move throttle stick to bottom within 2 seconds.
