The following is an explanation using the “Language” setting as an example
- Use the up button [ ]/ down button [ ] to select from the list, and press the menu button [ ] to confirm.
Function menu
Measurement display
< Battery connection>
When a battery is connected to the XT60i port
If you connect the battery to the XT60i port, only the total voltage is
displayed. To check the voltage of each cell, you need to connect the balance
connector of the battery to the balance port.
When a battery is connected to the balance port
When you connect the battery to the balance port, it displays the total
battery voltage, the maximum voltage difference between each cell, and the
voltage of each cell.
The icon displayed at the top of the left side of the screen differs depending on the port where the battery is inserted.
- You will see the following icons when you connect the XT60i port alone or both the XT60i port and the balanced port.
- If only the balance port is connected, the icon below will be displayed.
- If the battery is connected only to the balance port, you can start cell balancing by briefly pressing the menu button ( twice. (page.11)
- If the battery is connected to the XT60i port, you can start USB charging by briefly pressing the menu button [ twice. (page.13)
BEC power supply connection >
When you connect a BEC power supply to the XT60i port or balanced port, it
displays the BEC output voltage.
- Connect BEC power supply to XT60i port
- If you have an XT60i adapter, you can connect a BEC power supply to the XT60i port.
- The XT60i adapter is not available from Futaba.
Cell balance
If the battery is connected to the balance port, you can start cell balancing.
< Start of cell balance>
If the battery is connected only to the balance port, briefly press the menu
button [ twice to start cell balancing. Alternatively, select “Cell Balance”
from the “Function” menu, check the “Start” display, and press the menu button
( once. During the cell balancing operation, the left side of the screen turns
green, and the cell number being prepared on the right side of the screen is
displayed in orange.
When the “Power Save Mode” function is on, if no operation is detected during
operation, the display will turn off, and the LED will start blinking green to
signal that balancing is in operation.
If the battery is connected to the XT60i port, press the menu button [ once to
display the system function screen. Use the down button [ ] to move to cell
balance, and press the menu button [ once to start cell balancing.
- On the battery connection screen, Press the menu button [ once to display the system function screen.
- Press the down button [ ] to move to cell balance, and press the menu button [ once to start cell balancing
< End of cell balancee
When cell balancing is complete, the left side of the screen turns blue, and
an alarm sounds. This alarm sound will continue to sound at regular intervals
until the cell balance is stopped by the following operation. While the
display is off, the LED will start blinking blue to signal the end of
balancing.
< Stop cell balance>
Pressing the menu button [ twice brietly during or after cell balancing is in operation will stop cell balancing and return you to the battery connection screen.
After balancing is complete, stop immediately and be sure to remove the
battery.
If it is connected fora long time, it is very dangerous if it catches fire due
to over-discharge. Also, the battery will deteriorate.
USB Charge
Using the battery connected to the XT60i connector as a power source, you can
chargea device (battery) that supports USB charging from the USB charging port
.
Connect the battery to the XT60i port
< Start of USB charging>
Connect the battery to the XT60i connector, connect the battery to the USB
charging port with the charging cord, and device or battery press the menu
button [ ] twice to start USB charging. Alternatively, select “USB Charge”
from the “Function” menu, check the “Start” display, and press the menu button
[ ] once.
USB connection device (battery) information:
- :The device (battery) connected to the USB charging port supports Qualcomm QC 2.0/3.0
- :The device (battery) connected to USB charging port does not support Qualcomm QC 2.0/3.0
XT60i port input alarm voltage:
- If a NiNH or Pb battery is connected or the balance port is not connected, set it to the minimum operating voltage (5.0V) of BR-4000.
- When the balance port is connected Set to the single cell voltage set in “Low voltage alarm” in the system function menu.
- When the “Power Saving Mode” is on, the display turns off after 2 minutes of inactivity, and the LED starts blinking purple to indicate that USB charging is in operation.
- When the “Power Saving Mode” is on, the display turns off after 2 minutes of inactivity, and the LED starts blinking purple to indicate that USB charging is in operation.
USB charging will stop in the following cases.
- If the current exceeds 3A, USB charging will stop.
- USB charging will stop when the power exceeds 26W.
< Stop USB charging>
Usually, the device (battery) does not accept charging from the BR-4000 once
charging is complete, but the USB charging operation of the BR-4000 itself has
not stopped. To stop charging, use the following method.
Press the menu button [ ] twice briefly during or after USB charging is in operation to stop USB charging and return to the battery connection screen. Alternatively, select “USB Charge” from the “Function” menu, check the “Stop” display, and press the menu button [ once.
OAfter charging is complete, stop charging immediately and be sure to remove the battery from the XT60i port.
- If connected for a long time, it is very dangerous if it catches fire due to over-discharge. Also, the battery will deteriorate.
Receiver signal testing
If you connect the receiver’s channel connector or S.BUS connector to the
balanced port of BR-4000 with the optional DSC cable for T7PX/ 10PX, you can
check the RC control signal’s PWM and S.Bus signal.
< PWM>
You can check the RC control signal PWM of the system. The servo receiver
output signal is connected to the balance port, and the BR-4000 detects the
PWM output frame rate (cycle) and pulse width.
< S.BUS>
You can check the S.BUS signal. The S.BUS output signal is connected to the
balance port, and the BR- 4000 displays up to 18 channels of servo control
data, allowing you to check the signal position during F/S operation.
