Traxxas 3019R EVX-2 ESC with LVD User Manual download pdf

Thank you for purchasing the Traxxas EVX-2

electronic speed control. The EVX-2 delivers

smooth, precise, full-proportional control over your

speed in forward and reverse. EZ-Set® push-button

setup, multi-color LED, and three easy-to-program

drive profiles provide convenient, customized

operation. Low Voltage Detection enables the

EVX-2 to be used with LiPo batteries. The EVX-2

comes with the peace-of-mind of the Traxxas Lifetime Electronics

Warranty and unmatched Traxxas customer support. The EVX-2 is

not a toy. It is a sophisticated electronic device capable of delivering

large amounts of current. Children under 8 years of age require adult

supervision for use of the EVX-2. If you have questions or need assistance

call us at 1-888-TRAXXAS.

Important Precautions

Your EVX-2 is an extremely powerful electronic device capable of

delivering high current. Please closely follow these precautions to prevent

damage to the speed control or other components.

EVX-2 General Precautions

•

Disconnect the Batteries: Always disconnect the

battery packs from the speed control when not in use.

• Transmitter on First: Switch on your transmitter

ﬁrst before switching on the speed control to

prevent runaways and erratic performance.

• Don’t Get Burned: The transistor tabs and the

heat sinks can get extremely hot, so be careful not

to touch them until they cool. Supply adequate

airﬂow for cooling.

• Always Use Heat Sinks: Three heat sinks are

factory-installed on the speed control and must be

used for maximum cooling and performance.

• 6 to 14-cells; 2S to 4S LiPo Only: Always adhere

to the minimum and maximum limitations of the

EVX-2 as stated in the speciﬁcations table. Do not

mix battery types (NiMH or NiCad), brands or

capacities. Use the same voltage and capacity

for both batteries. Using mismatched battery

packs could damage the batteries and electronic

speed control.

• Connectors: If you decide to change the battery or motor connectors,

only change one battery or motor connector at a time. This will prevent

accidentally mis-wiring the speed control. If the EVX-2 is not wired

exactly as shown in the diagram below, it can be damaged! Please note

that modiﬁed speed controls can be subject to a rewiring fee when

returned for service.

• No Reverse Voltage: The speed control is not protected against reverse

polarity voltage. When changing the battery and/or motor, be sure to

install the same type of connectors to avoid reverse polarity damage

to the speed control. Removing the battery connectors on the speed

control or using the same-gender connectors on the speed control will

void the product’s warranty.

• Do Not Let the Transistor Tabs Touch: Never allow the three separate

transistor banks to touch each other or any exposed metal. This will

create a short circuit and damage the speed control. (For example, laying

a metal tool across the heat sinks can damage the speed control.)

EVX-2 Advanced Precautions

• Motor Limit: EVX-2 has a 12-turn 550 modiﬁed motor limit when the

motor is properly geared. If the motor or speed control is overheating,

try a smaller pinion gear. Do not attempt to use a more powerful motor

(fewer turns) than the above mentioned motor limits or you could

experience frequent thermal shutdown.

• Insulate the Wires: Always insulate exposed wiring with heat shrink

tubing to prevent short circuits.

• Use Neutrally Timed Motors: For reverse use, the motors must have

0° timing. Modiﬁed motors (with adjustable end bells) timed to 0° or

Johnson/ Mabuchi (closed end bell) motors are recommended. Using

motors with other than 0° timing will draw excess current in reverse, and

can result in the speed control overheating and premature motor wear.

• Motor Capacitors Required: Ceramic capacitors should be properly

installed on every motor to prevent radio interference. These are already

installed on the factory Titan motor.

• No Schottky Diodes: External schottky diodes are not compatible with

reversing speed controls. Using a schottky diode with the EVX-2 will

damage the ESC and void the 30-day warranty.

• Note: This speed control is not intended for marine use.

Installation

Here are some tips for choosing a location for the speed control:

• The EVX-2 does not use a conventional on/off switch. Pressing the EZ-Set

button on the speed control turns it on and off. It is not necessary to

install an on/off switch into the wiring harness.

• Make sure there is adequate ventilation for the heat sink. If you are

planning to operate the speed control at the higher limits of its

capabilities, cut ventilation holes into the body for the heat sinks. Proper

ventilation and cooling will prevent premature thermal shutdown.

• Mount the speed control where it will be protected from crash damage.

Protect the heat sinks from coming in contact with metal that could

short the banks of transistors. Also protect the speed control from dirt

and debris kicked up by the tires.

• Mount the speed control where you will have easy access to the plugs

and the on/off (EZ-Set) button without having to remove the body.

Troubleshooting Guide

This guide describes possible speed control problems, causes, and

simple solutions. Check these items before contacting Traxxas.

Steering channel works, but the motor(s) will not run:

• The motor(s) could be bad or have a damaged brush. Check the

motor(s) and motor connections by supplying power directly to

the motor(s). Note: Disconnect the motor(s) from the ESC before

testing. Remove the pinion gear from the motor(s) or elevate the

driving wheels to avoid a runaway and damage to the vehicle.

• The speed control has thermally shut down (look for a solid

green LED). Allow the speed control to cool down. See the

overheating section.

• Make sure the EVX-2’s power cable is plugged into the throttle

channel of the receiver (Channel 2). Check the operation of the

radio system’s throttle channel with a servo.

• Possible internal damage. Return the EVX-2 to Traxxas for service.

Motor and steering servo do not work:

• Check the wires, radio system, crystals, battery and motor

connectors, and the battery packs.

• Possible internal damage. Return the EVX-2 to Traxxas for service.

EVX-2 will not go into programming mode:

• Make sure the EVX-2 is plugged into Channel 2 (the throttle

channel) on the receiver. If it is plugged into Channel 3 or the

battery terminal, it will not go into programming mode.

• Be sure the EVX-2 is turned off before trying to program or select a profile.

• Unplug battery, reconnect, and repeat programming instructions.

Motor(s) run backwards:

• Motor(s) wired backwards: check the wiring and correct.

• Backwards motor timing: reverse the motor end bells.

Receiver glitches/throttle stutters during acceleration:

• Motor capacitors broken or missing: check and replace

the capacitors.

• The receiver or antenna is too close to power wires or batteries.

• Bad connections: check the wiring and connectors.

• Motor worn: replace the motor.

• Excessive current to the motor: use a milder motor or a smaller

pinion gear.

Model runs slowly / slow acceleration:

• Check the motor and battery connectors.

• Check to see if EVX-2 is in Profile #3 (50% throttle)

• Bad battery or motor: check the operation with known

good batteries (freshly charged) and motor.

• Incorrect transmitter or speed control adjustment. Reprogram

the EVX-2.

• Motor is improperly geared: use a milder motor or a smaller

pinion gear.

• Check the drive train for binding or restrictions.

EVX-2 overheats and shuts down:

• Overloading the motor (running through tall grass, binding

in the drivetrain).

• Insufficient ventilation for the heat sinks. Cut ventilation holes

in the body or relocate the EVX-2.

• Motor may exceed maximum specification. The EVX-2 is limited to

motors with no fewer than 19-turns (550 size) with molex connectors

and 12-turns (550 size) with Traxxas High-Current Connectors.

• Motor is improperly geared. Use a milder motor or a smaller

pinion gear.

• Check the drivetrain for restrictions.
