BEEP SOUND AND LED STATUS
The Meaning of Beep Sound LED Status
∞ 1 short Beep: The battery is NiMH/NiCd
∞ 2 short Beeps: The battery is 2S Lipo
∞ 3 short Beeps: The battery is 3S Lipo
∞ 1 long Beep: Self-test and throttle calibration is OK, the ESC is ready to run ∞
∞ Forward, brake or reverse at partial throttle, red LED blinks
∞ Forward, brake or reverse at full throttle, red LED is solid
THROTTLE SET THE ESC
PROTECTION FUNCTIONS
1. W O L VOLTAGE CUT OFF PROTECTION : If the voltage of battery pack is lower than the threshold for 2 seconds, the ESC will
enter the protection mode.
2S Lipo 3S Lipo 5-9 cells NiMH
Output reduces 50% at 6.5V
recovered
Output reduces 50% at 9.75V
recovered
Output reduces 50% at 4.5V
recovered
2. OVER EAT PROTECTION
: When the internal temperature of the ESC is higher than a factory preset threshold for 5
When the car stops, the red LED blinks to indicate the over-heat protection has been activated. If the ESC cools down to 80
Celsius degree, the output power is recovered to normal state.
3. THROTTLE SIGNAL LOSS PROTECTION
second.
TROUBLE SHOOTING
TROUBLE POSSIBLE REASON SOLUTION
After power on, motor can’t work, no
The ESC doesn’t get its working voltage; Connections
between battery pack and ESC are broken Check the battery wires connection or replace the
defective connectors
Switch is damaged Replace the switch
Polarity or battery type is wrong Check polarity and battery type
After power on, motor can’t work; red
LED blinks
Throttle signal is abnormal
Check the throttle wire connection; make sure it is
plugged into the throttle channel of the receiver
Automatic throttle range calibration is failed
Set the “TRIM” of throttle channel to 0 or turn the knob
to its neutral position
The motor runs in the opposite direction
The wire connections between ESC and the motor need
to be changed Swap two wire connections between the ESC and the
motor
The car can’t go backward
The jumper position is wrong Check the jumper and plug it to the correct position
The neutral point of throttle channel is changed or
drifted Set the “TRIM” of throttle channel to 0 or turn the knob
to its neutral position
The car can’t go forward, but can go
backward
The direction of throttle channel is not correct
Reset the direction of throttle channel from original
“NOR” to “REV”, or from original “REV” to “NOR”
The motor doesn’t work, but the LED in
the ESC works normally
The connections between motor and ESC are broken
Check the connections and replace the defective
connectors
Motor is damaged Replace the motor
The motor suddenly stops running while
in working state
The throttle signal is lost
Check the transmitter and the receiver.
Check the throttle wire connection
protection has been activated
Replace the battery pack, or cool down the ESC
The car cannot get top speed and the red
LED doesn’t solid on at full throttle
Some setting in the transmitter are incorrect
Set D/R, EPA, ATL to 100% or turn the knobs to
maximum value.
Set TRIM to 0 or turn the knob to its neutral position
Motor is cogging when accelerated
quickly
The battery has limited discharge ability Use battery with better discharge ability
Motor RPM is too high, the gear ratio is too aggressive
Use motor with lower RPM, or use smaller pinion to get
softer gear ratio
Something wrong in the driving system of the car Check the driving system of the car
The car doesn’t run straight
Steering TRIM is not adjusted correctly Make adjustment of the TRIM
Wheel nuts are too loose Tighten wheel nuts
