VKAR Bison - ESC Status, Alerts, and Protection; ESC LED Status Indicators; ESC Audible Alert Tones; ESC Protection Features

3. The LED Status in Normal Running
a) When the throttle stick is in the neutral range, neither the Red LED nor the Green LED lights up.
b) When the car moves forward, the Red LED solidly lights; the Green LED also lights up when the throttle stick is
at the top position (100% throttle).
c) When the car brakes, the Red LED solidly lights; the Green LED also lights up when the throttle stick is at the
bottom position and the maximum brake force is set to 100%.
d) When the car reverses, the Red LED solidly lights.
【
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 Lipo battery pack is lower than the threshold for 2 seconds,
the ESC will cut off the output power. Please note that the ESC cannot be restarted if the voltage of each Lipo
cell is lower than 3.5V.
For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V,
it will be considered as a 3S Lipo; If it is lower than 9.0V, it will be considered as a 2S Lipo. For example, if the
NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, it is considered as a 2S Lipo, 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 factory preset threshold for 5 seconds, the
ESC will cut off the output power. You can disable the over-heat protection function for competition race.
3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.
