Traxxas 3019R EVX-2 ESC with LVD - Manual (Page 2)

• Mount the speed control so that none of the power components (wiring,
motor, ESC) contacts any part of the radio system, particularly the
antenna wire. The receiver should be mounted so the antenna wire can
be extended as far away from the speed control as possible. The antenna
wire should be extended vertically in the mast and not wrapped on the
chassis under the body. Excess antenna wire should not be coiled on
the chassis. Servo cables and the antenna wire should not cross or come
in contact with any of the motor or battery wires. These steps will help
reduce the possibility of radio interference.
• Graphite or metal chassis have been known to transmit radio noise
generated by the motor. If the receiver is to be mounted on the chassis,
position it so the crystal and antenna are as far away from the chassis as
possible. This may require you to mount the receiver on its side. This will
reduce the chance of picking up radio interference from the motor.
• When mounting the speed control with double-sided servo tape, clean
both application surfaces thoroughly with alcohol to remove any
grease, dirt, oil, fingerprints, etc. The surfaces must be perfectly clean for
maximum adhesion.
• The motors require capacitors to reduce
the possibility of radio interference. If your
motors are not equipped with capacitors,
install the capacitors supplied with the EVX-2
as shown in the diagram below.
Transmitter Setup
Traxxas TQ Radio Systems
Before attempting to program your EVX-2, it is important to make
sure your TQ transmitter is properly adjusted (set back to the factory
defaults). Otherwise, you may not get the best performance from your
speed control. The transmitter should be adjusted as follows:
1. Set the throttle neutral switch to the 50/50 setting. This adjusts the
transmitter’s throttle trigger throw to 50% for throttle and 50% for
braking and reverse. Experienced users may wish to use the 70/30
setting if more broad proportional control is desired in forward
than with braking and reverse. This might be desirable in a racing
environment where reverse is disabled.
2. Set the throttle trim control to the middle “0” setting.
3. Set the Channel 2 servo reversing switch to the left position. Do
not change the position of any of the servo reversing switches after
programming the EVX-2.
4. You are now ready to program your speed control.
Aftermarket (Non-Traxxas) Transmitters
The following instructions are provided as a general reference only
for those who are using non-Traxxas transmitters. Consult your
transmitter’s instructions for information on how to change the settings.
1. Set the High ATV (adjustable travel volume) or EPA (end point
adjustment) to the maximum setting. This is the amount of servo throw
at full throttle.
2. Set the Low ATV, EPA or ATL (low side only trim adjustment) to the
maximum setting. This is the amount of servo throw at full brakes
or reverse.
3. Set the throttle trim to the middle (neutral setting).
4. Set the throttle channel reversing switch to either position. Do not
change the switch position after programming.
5. Set the trigger throw adjustment to 50% throttle and 50% brake (either
mechanical or electronic).
6. Set the exponential setting (if equipped) to the zero or fully
linear setting.
Aftermarket Receivers
The EVX-2 is compatible with most aftermarket receivers.
By removing the tab on the edge of the power connector,
the EVX-2 can be plugged directly into some models of
Futaba®, Airtronics®, Hitec®, and JR® receivers. Please refer
to the manufacturer’s wiring diagrams that came with
your receiver. On the EVX-2, the red wire is positive, the
black wire is negative, and the white wire is the control wire. Warning: On
some older Airtronics® radio systems, the positive and negative terminals
are opposite of the EVX-2 and an adapter is required. Crossing the red (+)
and black (-) wires could damage the receiver and the EVX-2. Study the
manufacturer’s wiring diagrams closely, or consult your hobby dealer.
EVX-2 Battery Setting (Low-Voltage Detection Setting)
The Low-Voltage Detection circuitry constantly monitors the battery
voltage. When the battery voltage begins to reach the minimum
recommended discharge voltage threshold for LiPo battery packs, the
EVX-2 will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the EVX-2 will shut
down all motor output. The LED on the speed control will slowly blink red,
indicating a low voltage shutdown. The EVX-2 will stay in this mode until a
fully charged battery is connected.
Your model includes a Power Cell NiMH battery. The EVX-2 speed control’s
Low Voltage Detection has been disabled for best performance with
this battery. The speed control’s LED will glow red when it is turned on,
indicating Low Voltage Detection is disabled. Be certain to activate Low-
Voltage Detection if you install LiPo batteries in your model. Never use
LiPo batteries while Low-Voltage Detection is disabled.
Verify that Low-Voltage Detection is DISABLED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery
pack to the EVX-2.
3. Press and release the EZ-Set button
to turn the EVX-2 on. If the LED is
solid red, then the Low-Voltage
Detection is DISABLED (not safe to
use LiPo batteries). If the LED is solid green, then Low-Voltage Detection
is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the EVX-2 is on and shines red.
2. Press and hold the EZ-Set® button
(the LED will turn off) (A). After
ten seconds, the motor will beep
twice and the LED will shine green.
Release the button (B).
3. Low-Voltage Detection is now
ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the EVX-2 is on and shines green.
2. Press and hold the EZ-Set® button
(the LED will turn off) (A). After ten
seconds, the motor will beep three
times and the LED will shine red.
Release the button (B).
3. Low-Voltage Detection is now
DISABLED.
Setup Programming (Calibrating your ESC and transmitter)
Read through all of the following programming steps before you begin.
If you get lost during programming or receive unexpected results, simply
unplug the battery, wait a few seconds, plug the battery
back in, and start over.
1. Disconnect each of the motor wires between the
EVX-2 and the motors. This is a precaution to prevent
runaway when the speed control is turned on before it
is programmed.
2. Connect two fully charged battery
packs to the EVX-2.
3. Turn on the transmitter (with the
throttle at neutral).
4. Press and hold the EZ-Set button (A).
The LED will first turn green and then
red. Release the EZ-Set button.
5. When the LED blinks RED ONCE. Pull
the throttle trigger to the full throttle
position and hold it there (B).
6. When the LED blinks RED TWICE.
Push the throttle trigger to the full
reverse and hold it there (C).
7. When the LED turns solid, programming is complete.
The LED will continuously shine red (Low-Voltage
Detection disabled) or green (Low-Voltage Detection
activated) indicating the EVX-2 is on and at neutral (D).
EVX-2 Operation
To operate the speed control and test the programming, reconnect the
motor wires and place the vehicle on a stable block or stand so that all of
the driven wheels are off the ground.
Note that in steps 1-8 below, Low-Voltage Detection is DISABLED (factory
default) and the LED shines red. If Low-Voltage Detection is ACTIVATED, the
LED will shine green instead of red in steps 1-8 below. Never use LiPo batteries
while Low-Voltage Detection is disabled.
1. With the transmitter on, press and release the EZ-Set button. The LED will
shine RED. This turns the EVX-2 on. If you press and release too quickly,
you may hear the steering servo jump but the LED may not stay on.
Simply press the button again until the LED shines RED and then release.
2. Apply forward throttle. The LED will turn off until full throttle power is
reached. At full throttle, the led will shine RED.
3. Move the trigger forward to apply the brakes. Note that braking control
is fully proportional. The LED will turn off until full braking power is
reached. At full brakes, the LED will shine RED.
4. Return the throttle trigger to neutral. The LED will shine RED.
5. Move the throttle trigger forward again to engage reverse (Profile #1).
The LED will turn off. Once full reverse power is reached, the LED will
shine RED.
6. To stop, return the throttle trigger to neutral. Note that there is no
programmed delay when changing from reverse to forward. Use caution
to avoid slamming the speed control from reverse to forward. On high-
traction surfaces, this could result in transmission or driveline damage.
7. To turn the EVX-2 off, press and hold the EZ-Set button for 1½ seconds or
until the red LED turns off.
8. The EVX-2 is equipped with thermal shutdown protection to guard
against overheating caused by excessive current flow. If the operating
temperature exceeds safe limits, the EVX-2 will automatically shut
down. The LED on the face of the EVX-2 will rapidly blink red, even if the
throttle trigger is moved back and forth. Once the temperature returns
to a safe level, the EVX-2 will once again function normally.
Throttle Neutral Protection
Your model’s EVX-2 speed control also features Throttle Neutral Protection.
If the transmitter’s throttle trim setting is changed while the speed control
is switched off, Throttle Neutral Protection prevents the speed control from
activating the motor until the throttle trim is corrected. Throttle Neutral
Protection also prevents the model from suddenly accelerating if the speed
control is switched on while the transmitter’s trigger is being held. When
the trigger is returned to neutral, the EVX-2 will operate properly.
EVX-2 Profile Selection
The speed control is factory set to Sport Mode (100% forward, brakes, and
reverse). To disable reverse (Race Mode) or to allow 50% power (patent
pending Training Mode), follow these steps. The speed control should
be connected to the receiver and the transmitter adjusted as described
previously. The profiles are selected by entering the programming mode.

LED Codes and Protection Modes
• Solid Green: EVX-2 power-on light. Low-Voltage Detection is ACTIVATED
(LiPo setting).
• Solid Red: EVX-2 power-on light. Low-Voltage Detection is DISABLED
(NiCad/NiMH setting). Never use LiPo batteries while Low-Voltage
Detection is disabled.
• Fast Blinking Red: The EVX-2 is equipped with thermal shutdown
protection to guard against overheating caused by excessive current
flow. If the operating temperature exceeds safe limits, the EVX-2 will
automatically shut down. Let the EVX-2 cool. Make sure your model is
properly geared for the conditions.
• Slow Blinking Red (with Low-Voltage Detection on): The EVX-2 has
entered Low-Voltage Protection. When the battery voltage begins to
reach the minimum recommended discharge voltage threshold for LiPo
battery packs, the EVX-2 will limit the power output to 50% throttle. When
the battery voltage attempts to fall below the minimum threshold, the
EVX-2 will shut down all motor output. The LED on the speed control will
slowly blink red, indicating a low-voltage shutdown. The EVX-2 will stay in
this mode until a fully charged battery is connected.
• Fast Blinking Green: The EVX-2’s LED will blink fast green if Throttle
Neutral Protection is activated, or if the speed control is not receiving
a signal. Make certain the speed control is properly plugged into the
receiver and the transmitter is switched on. If this does not restore normal
operation, then the EVX-2 is indicating the transmitter’s Throttle Trim is
incorrectly set. Reset the throttle trim to the “0” position.
• Flashing Red and Green: The EVX-2 has entered Over Voltage Protection.
If a battery with too high voltage (over 14.8 volts) is used, the EVX-2 will
go into a failsafe mode.
