Troubleshooting - Hobbytech NXT SPIRIT EP 2.0 Manual De Instrucciones

Note2: If you don't release the "SET" key after the red LED begins to flash, the ESC will enter the program mode, in such a case,
please switch off the ESC and re-calibrate the throttle range again from step A to step D.
C) Set the 3 points according to the steps shown as the
pictures on the rigHT-side.
1) The neutral point
Move the throttle stick at the neutral point, and then
click the SET key, the green LED flashes 1 time.
2) The end point of forward direction
Move the throttle stick at the end point of forward
direction, and then click the SET key, the green LED
flashes 2 times.
3) The end point of backward direction
Move the throttle stick at the end point of backward
direction, and then click the SET key, the green LED
flashes 3 times.
D) Throttle range is calibrated; motor can be started after
3 seconds.
3. Check the LED Status in Normal Running
1) Normally, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
2) The red LED lights when the car is running forward or backward and it will flash quickly when the car is braking
3) The green LED lights when the throttle stick is moved to the top point (end point) of the forward zone.
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.
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.
TROUBLE SHOOTING
TROUBLE
After power on, motor doesn't work,
and the cooling fan doesn't work
After power on, motor can't work, but
emits "beep-beep-, beep-beep-" alert
tone. (Every "beep-beep-" has a time
interval of 1 second )
After power on, red LED always lights, the
motor doesn't work
The motor runs in the opposite direction
when it is accelerated
The motor suddenly stops running while in
working state
Random stop or restart irregular working
state
When the throttle stick is in the neutral
range, the red LED and the green LED
flashes synchronously
Cannot connected with the LED Program
Card or LCD Program Box
10
POSSIBLE REASON
The connections between battery pack and
ESC are not correct
Input voltage is abnormal, too high or too
low
Throttle signal is abnormal
1) The wire connections between ESC and
the motor are not correct
2) The chassis is different from the popular
design
The throttle signal is lost
The ESC has entered the Low Voltage
Protection Mode or Over-heat Protection
Mode
1) Some connections are not reliable
2) Wrong charge of the battery pack
3) Gear ratio is too long
4) Start mode (punch) is too agressive
Over current protection, motor
demagnetization, or motor is over load
Mistakenly uses the Rx wire to connect to
the program card/box
SOLUTION
Check the power connections
Check the voltage of the battery pack
Plug the control wire into the throttle channel of the
receiver correctly.
Method #1: Swap any two wire connections between the
ESC and the motor
Method #2: Change the "Motor Rotation" programmable
item to "CW(Clockwise)"
Check the transmitter and the receiver
Check the signal wire from the throttle channel of your
receiver
Red LED flashes means Low Voltage Green LED flashes
means Over-heat
1) Check all the connections: battery pack connections,
throttle signal wire, and motor connections, etc.
2) Replace the battery pack
3) Change the gear ratio
4) Go down the Start Mode to a softer value
1) Reduce the load (use softer gear ratio or reduce the
input voltage)
2) Change the motor
Connect the program card/box to the special
programming port of tthe ESC, don't use the Rx wire
