WATER-PROOF

SENSORLESS BRUSHLESS

SPEED CONTROLLER

【DECLARATION】 Thanks for purchasing “EZRUN” series Electronic Speed Controller (ESC). The power system for RC model can be very dangerous, so please read this manual carefully. In that we have no control over the correct use, installation, application, or maintenance of our products, no liability shall be assumed nor accepted for any damages, losses or costs resulting from the use of the product.

(After running the ESC on wet track, please clean and dry it to avoid the oxidation to copper connectors)

2. Specially designed for RC car and truck, with excellent start-up, acceleration and linearity features.

3. Compatible with sensorless brushless motor.

4. 3 running modes suitable for different applications (“Forward with brake” mode, “Forward/Backward with brake” mode and “Rock crawler” mode).

5. 4 steps of maximum reverse force adjustment.

6. Proportional ABS brake function with 4 steps of maximum brake force adjustment, 8 steps of drag-brake force adjustment and 4 steps of initial brake force adjustment.

7. 9 start modes (“Punch”) from “Soft” to “Very aggressive” to be suitable for different chassis, tires and tracks.

8. Multiple protection features: Low voltage cut-off protection for Lipo or NiMH battery / Over-heat protection / Throttle signal loss protection / Motor blocked protection.

9. 8 steps of timing adjustment.

10. Several programming methods are supported, such as: The “SET” button on the ESC, the LED Program Card, the advanced LCD Program Box, and the PC Software.

11. The firmware of ESC can be online updated through an USB adapter on the advanced LCD program box.

【SPECIFICATIONS】

Note1: For information about the high voltage cooling fan, please refer to the brief introduction on page 4.

【BEGIN TO USE THE NEW ESC】

1. Connect the ESC, motor, receiver,

battery and servo according to the following diagram

“+” and “-” wires of the ESC are connected with the battery pack, and #A, #B and #C are connected with the motor wires. The “SET” button is used for programming the ESC.

The control cable of the ESC (trio wires

with black, red and white color) is connected with the throttle channel of the receiver (Usually CH2).

The #A, #B, #C wires of the ESC can be

connected with the motor wires freely

A) Switch off the ESC, turn on the

transmitter, set the direction of throttle channel to ”REV”, set the “EPA/ATV” value of throttle channel to “100%”, and disable the “ABS” brake function of your transmitter. (*Note2)

B) Hold the “SET” key and then switch on

the ESC, when the red LED begins to flash, release the key immediately.

(Please check the picture on the right side)

C) Set the THREE points according to the

steps shown in the picture on the right side.

1) Neutral point

2) End point of forward direction

3) End point of backward direction

D) When the process of calibration is

finished, the motor can be started after 3 seconds.

(without any order). If the motor runs in the opposite direction, please swap any two wire connections.

Note: You can use the transmitter to set the throttle channel to the “Reverse” direction, and then the motor

will run oppositely. Please calibrate the throttle range again after changing the direction of throttle channel.

2. Throttle Range Setting (Throttle Range Calibration)

In order to make the ESC match the throttle range, you must calibrate it when you begin to use a new ESC, or a new transmitter, or after changing the settings of the neutral position of throttle channel, ATV or EPA parameters, otherwise the ESC cannot work properly. There are 3 points need to be set, they are the top point of “forward”,” backward” and the neutral point. The following pictures show how to set the throttle range with a Futaba

transmitter.

【PROGRAM THE ESC】

1. Program Method

Note2: If you don’t release the “SET” key after the

red LED begins to flash, the ESC will enter the program mode, in such a case, please switch off the ESC and re-calibrate the throttle range again from step A to step D.

3. The LED Status in Normal Running

a) In normal use, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights. b) The red LED lights when the car is run forward or backward and it will flash quickly when the car is braking. c) The green LED lights when the throttle stick is moved to the top point of the forward zone (that is: full throttle).

【ALERT TONES】

1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if it is out of the normal range, such an alert tone will be emitted: “beep-beep-, beep-beep-, beep-beep-” (There is 1 second time interval between every “beep-beep-” tone).

2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-, beep-, beep-” (There is 2 seconds time interval between every “beep-” tone).

【PROTECTION FUNCTION】

1. Low voltage cut-off protection: If the voltage of a Lipo battery pack is lower than the threshold for 2 seconds, the ESC will cut of the output power. Please note that the ESC cannot be restarted if the voltage of each Lipo cell is lower than 3.5V. For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V, it will be considered as a 3S Lipo; If it is lower than 9.0V, it will be considered as a 2S Lipo. For example, if the NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, it is considered as a 2S Lipo, and the low-voltage cut-off threshold for this NiMH battery pack is 2.6*2=5.2V.

2. Over-heat protection: When the temperature of the ESC is over a factory preset threshold for 5 seconds, the ESC will cut off the output power. You can disable the over-heat protection function for competition race.

3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.

Note:

 In the program process, the motor will emit “Beep” tone at the same time when the LED is flashing.  If the “N” is bigger than the number “5”, we use a long time flash and long “Beep---” tone to represent “5”,

so it is easy to identify the items of the big number. For example, if the LED flashes as the following:

“A long time flash + a short time flash” (Motor sounds “Beep---Beep”) = the No. 6 item “A long time flash + 2 short time flash” (Motor sounds “Beep---BeepBeep”) = the No. 7 item “A long time flash + 3 short time flash” (Motor sounds “Beep---BeepBeepBeep”) = the No. 8 item

And so on.
