Onyx ONXM1040 User manual

Thank you for purchasing the ONYX electronic speed controller
(ESC). Operating RC models can be very dangerous, so please read
this manual carefully. This ESC is designed specically for crawlers
and tanks. It is not intended for use with racing-style vehicles.
Please read and understand all warnings before installation
and operation!
OPERATIONAL WARNINGS!
●Disconnect the battery from the ESC immediately if the ESC or
battery becomes hot! Allow the ESC or battery to cool down
before reconnecting.
● NEVER use more than the specied voltage on the ESC’s input.
●ALWAYS mount the ESC in a position where air can ow through
the heat sink during operation.
●ALWAYS turn on the transmitter before connecting the battery to
the ESC.
●ALWAYS disconnect the battery from the ESC when not in use.
●ALWAYS remove the pinion gear when making programming
changes. This will prevent the model from taking off accidentally.
●DO NOT use with brushless motors.
●ALWAYS set the battery type to LiPo when using a LiPo battery.
This will turn on the LVC.
●ALWAYS use heat-shrink tubing to insulate any bare wires to
prevent a short circuit.
●ALWAYS allow the ESC to cool before touching. It is normal for
ESCs to get warm during operation.
●DO NOT allow metal/conductive materials to accidentally make
contact across any or all motor/battery posts.
●NEVER power up the ESC before plugging it into the Rx and
switching on the transmitter (Tx).
●ALWAYS keep out of reach of children.
●ONYX is not responsible for incidental damage or personal
injury as a result of misuse of this product.
LITHIUM BATTERY CAUTIONS!
This product may use a lithium polymer (LiPo) battery.
Improper handling could result in FIRE! A lithium battery
re has the potential to ignite surrounding areas and may
cause property damage or cause personal injury.
●ALWAYS set the ESC to LiPo battery mode to prevent over
discharging.
●NEVER leave a LiPo battery unattended while charging or during
operation.
●NEVER operate a vehicle with a LiPo battery inside a building.
●IMPORTANT! Always unplug the LiPo battery immediately when
nished operating your vehicle.
●ALWAYS charge and store LiPo batteries in a reproof location.
Never store LiPo batteries inside the model.
●If you ever see a LiPo battery puff or smoke during operation,
immediately disconnect the battery and move the entire model,
with the battery installed, to a reproof location (outside if possible).
●Consult the battery and charger instruction manuals.

ESC SETUP
1. CONNECT THE ESC.
A. Connect the ESC to the motor. Yellow to the positive (+) side of
the motor. Blue to the negative (-) side of the motor.
B. Connect the ESC’s Rx lead to the throttle channel of the receiver
(typically CH2).
C. Connect the “+” and “–” battery wires of the ESC to the battery pack.
CAUTION! Incorrect polarity will damage the ESC immediately.
2. TRANSMITTER SETUP
A. Set the “D/R”, “EPA” and “ATL” to 100% for throttle channel.
B. Set the “TRIM” of the throttle channel to center.
NOTE: For Futaba and Tactic transmitters, the direction of throttle
channel must be set to “REV”. Other radio systems may be different.
Consult your transmitter’s manual to be sure.
IMPORTANT! Always use the Failsafe in your radio system. Set it up
so the throttle moves to zero.
3. THROTTLE CALIBRATION
Every time you turn on the ESC, the throttle will calibrate. First turn
on your transmitter and keep the throttle at neutral. Next, turn on the
ESC. Once you hear the long beep, you are ready to go.
NOTE: When changing settings of the throttle channel, (D/R, ATV,
ATL or EPA), always restart the ESC to recalibrate.
™

4. OPERATION STATUS
•When the throttle is at neutral, the red LED is off.
•Forward or reverse at partial throttle, the red LED blinks.
•Forward or reverse at full throttle, the red LED is solid.
5. PROGRAMMING THE ESC
The ESC is programmed by using jumper connectors placed in specic
locations. (Tweezers are recommended to plug and unplug the jumper.)
The chart shows the jumper positions for programming the drag brake
and for selecting battery type.
IMPORTANT! If running a LiPo battery, you MUST use the LiPo setting
to protect the battery from over-discharging.

OPERATION
1. This ESC is optimized for crawlers, scale trucks, tanks, and boats.
It is not designed for race vehicles.
2. For tanks, two ESCs are needed—one ESC connected to each
side. Using a two-stick radio or a wheel radio with mixing, you will
be able to independently control each track.
3. When you move the throttle trigger from forward to backward, the
vehicle will immediately move backward. This setup is desired in
rock crawlers and tanks, so that you will have quick control in both
directions if you get stuck.
4. This ESC uses an automatic drag brake. 100% gives you full brake
when letting go of the trigger. 50% gives you half brakes. 0% is no
brakes and changes reverse to 25% of forward. This is the best
setting for boats, where you do not want a high speed reverse.
CAUTION!
Using this ESC will take practice. Quick movements from
forward to reverse may put additional strain on the motors, driveline,
and ESC. Smooth movements will yield the best operational experience.
SAFETY SYSTEMS
Low Voltage Cut-Off (LVC) Protection: If the battery voltage is
lower than the cut-off voltage for 2 seconds, the ESC will enter the
protection mode. When the vehicle stops, the red LED will blink to
indicate the low voltage cut-off protection has been activated.
LVC CHART
3S LiPo Throttle reduces to 50% at 9.75V, cuts off at 9.0V.
5-9 Cell NiMH Throttle reduces to 50% at 4.5V, cuts off at 4.0V.
2S LiPo Throttle reduces to 50% at 6.5V, cuts off at 6.0V.
Thermal Protection: When the internal temperature of the ESC is
higher than 212° F (100° C) for 5 seconds, the ESC will reduce and
cut off the output power. The vehicle will stop and the red LED blinks
to indicate the thermal protection has been activated. When the ESC
cools down to 176° F (80° C), the ESC will reset to normal.
Throttle Signal Loss Protection: The ESC will shut down the motor
if the throttle signal has been lost for 0.1 seconds.

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
After powering on, the motor will not work,
no sound is emitted, and the LED is off.
The vehicle won’t go in reverse.
The car runs in reverse while giving throttle.
(The motor runs in the opposite direction).
The wire connections between ESC
and the motor are wrong.
Swap the wire connections between the ESC and the motor.
After powering on, the motor won’t work
and the red LED blinks. Throttle range calibration failed. Set the “TRIM” of throttle channel to its neutral position.
Throttle signal is abnormal. Check the receiver connection; make sure it is
plugged securely into the throttle channel.
Switch may be damaged. Replace the switch.
Check the connections between the
battery pack and the ESC.
Check the battery connection or replace the
defective connectors.
The motor doesn’t work, but the LED in the
ESC is working normally.
The vehicle can’t go forward, but can go in
reverse.
The direction of the throttle channel is
not correct.
Reset the direction of the throttle channel
(NOR ➡ REV or REV ➡ NOR).
The connection between the motor and
ESC is broken.
Check the connections and replace the
defective connector(s).
The motor is damaged. Replace the motor.
The jumper position is incorrect. Check the jumper and plug it into the correct position.
The neutral point of the throttle channel
is incorrect.
Set the “TRIM” of the throttle channel to its
neutral position.
The motor suddenly stops running during
operation.
The vehicle cannot reach top speed and the
red LED doesn’t read solid at full throttle.
Transmitter settings are incorrect. Set D/R, EPA, ATL to 100% and set the TRIM
to its neutral position.
The throttle signal is lost. Check the Tx batteries and the the Rx connections.
LVC or Thermal Protection has been activated. Replace the battery pack or cool down the ESC.
The motor stutters during quick accleration.
The battery is unable to handle the motor draw. Use a battery with better discharge (greater “C” value).
Motor RPM is too high and/or the gear
ratio is too aggressive.
Use a motor with lower RPM or use a smaller pinion.
A chassis problem is causing drivetrain drag. Check the drivetrain in the vehicle.
