Error signal during driving (LED flashing pattern)
When the ESC battery terminal voltage drops to the cut-off
voltage set on P.16, the standby LED lights up and flashes,
and the green LED will be flashed and drive speed is going
to low.
LED green blinks and runs at low speed ~ Low voltage cut-off
Protection circuit for Battery reverse connection
This product is equipped with a reverse battery protection
circuit, so the ESC circuit is protected if the reverse
connection less than about 10 seconds. (Some heat is
generated when the protection circuit is activated.)
When the battery is connected in reverse, the LED on the
back of the battery terminal will turn red. Remove the
battery immediately and reconnect it correctly.
※
The protection circuit is automatically activated
when the battery is reversely connected.
When the ESC overheats due to driving and reaches the
specified temperature, the orange LED blinks in addition to
the standby LED lighting / flashing, and the vehicle runs at
low speed.
In this case, stop driving until the ESC temperature drops.
If the heat protection is activated in a short driving time, the gear ratio setting may be
overloaded. In this case, check each setting status.

Important
The condition to detect the cut-off voltage is not “Battery voltage” but “ESC battery
terminal voltage”. If the contact condition of the connector to which the battery is
connected and the welded state of the solder bonding the connector are
insufficient, that portion will have a large electrical resistance, and the voltage
detected at the ESC terminal will be far below the battery voltage.
If there is a large difference between the set cut-off voltage and the actual battery
voltage at the time of cut-off operation, the reason may be due to the connector to
which the battery is connected or the solder welding location of the connector.
In such cases, the ESC or motor performance may not be fully achieved. It is
recommended to replace the connector or rework the solder.
Important
This function protects only the ESC circuit board when the battery is reversely
connected. Capacitors connected to ESC such as Chevalier series are not
protected, so be careful when connecting batteries.
