Hard Cut Off
Using Your New ESC
Improper polarity or short circuit will damage the ESC therefore it is your responsibility to double check
all plugs for proper polarity and first fit BEFORE connecting the battery pack.
Alert Tones
The ZTW ESC is equipped with audible alert tones to indicate abnormal conditions at power up.
1. Continuous beeping tone (****) – Indicates that throttle stick is not in the minimum position.
2. Single beeping tone followed by a one second pause (* * * *)– Indicates that the battery pack
voltage exceeds the acceptable range. (The ESC automatically checks and verifies the battery voltage
once the battery is connected).
Built-in Intelligent ESC Safety Functions
1.
Over-heat protection
: When the temperature of ESC exceeds 110 deg C, the ESC will reduce the
output power to allow it too cool.
2.
Lost Throttle signal protection
: The ESC will automatically cut power to the motor when it detects
a lost of throttle signal for 2 seconds, then the motor will emit continuous beeping tone.
POWERING UP THE ESC FOR THE FIRST TIME & SETTING THE AUTOMATIC THROTTLE
CALIBRATION
The ZTW ESC features Automatic Throttle Calibration to attain the smoothest throttle response and
resolution throughout the entire throttle range of your transmitter. This step is done once to allow the
ESC to “learn and memorize” your Transmitter’s throttle output signals and only repeated if you change
your transmitter.
1.Switch your Transmitter ON and set the throttle stick to its maximum position.
2.Connect the battery pack to the ESC. Wait for about 2 seconds, the motor will beep for twice, then put
the throttle in the minimum position, the motor will also beep, which indicates that your ESC has got the
signal range of the throttle from your transmitter.
The throttle is now calibrated and your ESC is ready for operation.
ENTERING THE PROGRAMMING MODE
1.
Switch your Transmitter
ON
and set the throttle to its
maximum
position.
2.
Connect the battery pack to the ESC.
3.
Wait until you hear two short beeps (
●●
●●
●●
●●
) confirming that the ESC has now entered the
programming mode.
4.
If the throttle stick is left in the
maximum
position beyond 5 seconds, the ESC will begin the
sequence from one function and its associated setting options to another. (Please refer to the table
below to cross reference the functions with the audible tones).
5.
When the desired tone for the function and setting option is reached, move the throttle stick down
to its
minimum
position. ESC will emit two beeps (**) confirming the new setting has been stored.
6.
The ESC only allows the setting of one function at a time.
Therefore should you require making changes to other function, disconnect the battery
