BRUSHLESS ESC
•
Always monitor ESC, motor and battery temperatures during running.
•
Disconnect the battery from the ESC immediately if the ESC or battery becomes hot. Allow the ESC or battery
to cool completely before reconnecting.
•
Never use more than a 2S LiPo or 7-cell NiMH battery.
•
Always disconnect the battery from the ESC when not in use.
•
Make sure the battery is fully charged before connecting to the ESC.
•
Do not attempt to use the brushless ESC with a brushed motor.
•
The ESC may become hot during running. Allow the ESC to cool before touching.
•
Never turn on the ESC before plugging it into the receiver and switching on the transmitter.
•
Dromida is not responsible for incidental damage or personal injury as a result of misuse of this product.
THROTTLE CALIBRATION
Before the ESC can be used, throttle calibration must be performed to ensure the throttle is set up properly. Be
sure that your throttle trim is set to ZERO before performing calibration and that throttle end points and dual rates
are set to maximum.
Note: We recommend that you prop the vehicle up off the ground to prevent it from driving off the surface in case
the calibration is not performed properly.
1. With the ESC turned off, turn on the transmitter.
2. Press and hold the "SET" button on the on/off switch. Then, switch on the ESC.
When the red LED begins to flash, release the button immediately.
3. With the transmitter throttle at neutral, press and release the ESC
"SET" button. The green LED should flash one time.
4. With the transmitter throttle at full throttle, press and release the ESC
"SET" button. The green LED should flash two times.
5. With the transmitter throttle at full reverse, press and release the ESC
"SET" button. The green LED should flash three times.
6. After the calibration is completed, wait at least three seconds before giving any transmitter input.
NOTE: If you do not release the "SET" button once the red LED begins to flash, the ESC will enter the program
mode. If this happens turn the ESC off and start over.
LED STATUS IN NORMAL RUNNING
•
When the throttle is at neutral, all LEDs should be off.
•
When running forward, the red LED will illuminate.
•
At full throttle, the Red and Green LEDs will illuminate.
•
During braking, the red LED will flash quickly.
ALERT TONES
When you turn on the ESC it checks the battery's voltage. If the battery is out of the normal voltage range it will
alert you with a "beep-beep....beep-beep....beep-beep."
If the throttle signal is abnormal it will alert with a "beep.........beep........beep."
VOLTAGE PROTECTION
The Dromida brushless ESC is equipped with a "LVC" (Low Voltage Cut-off) to protect LiPo batteries from being
drained too low. If the LiPo battery is lower than the designated cut-off for more than 2 seconds the ESC will cut
off the output power. The ESC cannot be restarted if the voltage of each LiPo cell is lower than 3.5V. If using a
non-LiPo pack, be sure to adjust the ESC to its No-Cutoff Option ("No LVC") to maximize run time.
OVERHEAT PROTECTION
If the temperature of the ESC is over the factory preset temperature for 5 seconds, the ESC will cut off the output
power. If this happens, check for binding or broken parts on the vehicle.
THROTTLE SIGNAL LOSS PROTECTION
The ESC will cut off the output power if the throttle signal from the transmitter is lost for 0.2 seconds.
