7.1.8
WARNING_CODE_CURRENT
If the battery drawn current is more than 21A, this warning code is generated. This warning doesn’t limit anything.
7.1.9
WARNING_CODE_SPEED_TILT_BACK
If the skateboard speed is equal or greater than the maximum allowed speed (also called speed limit), this warning code
is generated. This warning code limits the speed of skateboard. The speed limit is calculated from the control mode and
user speed settings on mobile application (balance control mode), speed levels (remote control mode), battery remaining
capacity and other warnings that limit the speed forcefully. When the battery remaining capacity is less than 30 percent,
the speed is limited linearly with decrease in battery level till 5 percent where the speed is already limited up-to 5 km/h.
7.1.10
WARNING_CODE_LOW_BATTERY
If the skateboard battery level is less than 5 percent or remote battery is less than 10 percent, this warning code is
generated. This warning code limits the skateboard speed up-to 5 Km/h. If the remote battery level is less than 10
percent and skateboard speed is high, the skateboard speed first decays to 5 Km/h and then the remote is automatically
switched off. The skateboard doesn’t let the remote control to power on unless it is recharged. In case of skateboard, if
the battery level is 0 percent already for more than 60 seconds, the motors output power is cut off and error code is
generated. There are other protections on battery voltage that monitor the under-voltage and over-voltage conditions
which shuts down the mother board.
7.1.11
WARNING_CODE_GET_ON_WEIGHT_IS_OUT_OF_RANGE
The rider’s weight for the balance control should be at least more than 20 Kg. If it’s less than 20 Kg, this warning is
generated followed by 3 beeps and the balance mode is not entered.
7.1.12
WARNING_REMOTE_THROTTL_STICK_OUT_OF_RANGE
When the remote control is powered on, the stick position must be at mean position. If somehow, the position is not in
the center, this warning is generated followed by 3 beeps. This warning persists unless the stick position is brought back
to mean position.
Note: If the stick position is in the mean position and still the warning is being generated, there could be two reasons i.e.
either the throttle stick mean position is not calibrated or the stick wires are internally broken. To recalibrate the stick
position, please follow the stick position calibration section explained in remote chapter.
7.2
Error Codes
The error codes are generated and logged in the memory in safety critical conditions. In all types of error codes, the
motors’ output power is cut off, buzzer alarm is generated continuously and mobile application shows the error code
number. The error code number can also be decoded from the number of long beeps followed by the number of short
beeps by the buzzer. The number of long beeps represents the tens digit and while the number of short beeps represents
the unit digit. For example, the error code number 59 will generated 5 longer beeps followed by 9 short beeps in a
periodic manner. The details of error codes are kept hidden from the end user. In case of error code, the user should try
to power off the skateboard and power on again. If the error code still persists, the user should report to our after sales.
7.3
Safety Shutdown
When the skateboard is powered on, the buzzer beeps once which shows a normal start up. But if the buzzer beeps twice
soon after powered on, it indicates the last shutdown was not normal. There are some cases, where the safety shut down
is performed to protect the hardware in some cases. There can be several reason which are logged in the memory before
