【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
User Manual of “EZRUN” Series Splash-Proof Brushless Speed Controller HW-SM411ENG-20120630 Page - 2 -
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
TM
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.

2. Programmable Items list
3.9. Timing: There are many differences among structures and technical features of different brushless motors; an
ESC with fixed timing cannot be compatible with all brushless motors, so it is necessary to make the timing value
programmable. Please select the most suitable timing value according to the motor you are just using. Generally,
higher timing creates bigger power output, but the whole efficiency of the system will be slightly lower.
3.10. Over-Heat Protection: If the function is activated, the output power will be cut-off when the temperature of
the ESC is higher than a factory preset threshold for more than 5 seconds. When the protection happens, the
Green LED flashes.
4. Reset All Items To Default Values
At any time when the throttle is located in neutral zone (except in the throttle calibration or programming mode),
Attention: The italics texts in the above form are the default settings.
3. Programmable Values
3.1. Running Mode: With “Forward with Brake” mode, the car can go forward and brake, but cannot go backward,
this mode is suitable for competition; “Forward/Reverse with Brake” mode provides backward function, which is
hold the “SET” key for over 3 seconds, the red LED and green LED will flash at the same time , which means each
programmable item has be reset to its default value.
【TROUBLE SHOOTING】
suitable for training. The “Rock Crawler” mode is only used for rock crawler.
Note: “Forward/Reverse with Brake” mode uses “Double-Click” method to make the car go backward.
When you move the throttle stick from forward zone to backward zone for the first time, the ESC begins to brake
the motor, the motor speeds down but it is still running, not completely stopped, so the backward action is NOT
happened now. When the throttle stick is moved to the backward zone again (The 2nd “click”), if the motor speed is
slowed down to zero (i.e. stopped), the backward action will be occurred. The “Double-Click” method can prevent
mistakenly reverse when the brake function is frequently used in steering.
With “Rock Crawler” mode, the reverse action will be happened immediately when the throttle stick is moved to
backward zone. Please set the “Drag Brake Force” to 100% if you choose the “Rock Crawler” mode.
3.2. Drag Brake Force: Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect
of a neutral brushed motor while coasting.
3.3. Low Voltage Cut-Off: The function is mainly used to prevent the Lipo battery from over discharging. The ESC
monitors the battery’s voltage at any time, if the voltage is lower than the threshold, the output power will be
reduced to 50% in 2 seconds. Please drive to the side of racing track as soon as possible and then stop the car,
the ESC will completely cut off the output power in 10 seconds.
3.4. Start Mode (Also called “Punch”): Select from “Level1 (Soft)” to “Level 9 (Very aggressive)” start mode as
your like. Please note that if you choose “Level 7” to “Level 9”, you’d better use good quality battery pack with
powerful discharge ability, otherwise these modes cannot get the bursting start effect as you want. If the motor
cannot run smoothly (the motor is trembling), it may caused by the weak discharge ability of the battery pack,
please choose a better battery or increase the gear rate.
3.5. Maximum Brake Force: The ESC provides proportional brake function. The brake force is related to the
position of the throttle stick. Maximum brake force refers to the force when the throttle stick is located at the top
point of the backward zone. A very large brake force can shorten the brake time, but it may damage the gears.
3.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction. Different value
makes different reverse speed.
3.7. Initial Brake Force: It is also called “minimum brake force”, and it refers to the force when the throttle stick is
located at the initial position of the backward zone. The default value is equal to the drag brake force, so the brake
effect can be very smooth.
3.8. Throttle Neutral Range: Please see the following illustrations to adjust the neutral range.

【OPTIONAL ACCESSORIES FOR UPGRADE】
We provide the following optional accessories for upgrade your power system:
1. Cooling fan (12V): The high voltage fan is necessary when you are using 3S
Lipo or NiMH battery more than 6 cells.
WARNING! Please note the original cooling fan (5V) can only work with 2S Lipo
or 4-6 cells NiMH battery. DON’T use it with a 3S Lipo or NiMH battery more than 6
cells. Please check the label of the cooling fan carefully to confirm its working
voltage before using it.
2. LED Program Card (Digital LED Display).
The Program card is an optional accessory which needs to be purchased separately. It
has a friendly user interface. The process of programming the ESC becomes quite
easy and fast with this pocket sized device.
3. Advanced LCD Program Box (LCD Display).
Advanced Program Box is an optional accessory which needs to be purchased
separately.
It has LCD display to show the programmable items, so it can work as an individual
device to set the ESC. And it also works as an USB adapter to connect the ESC with a
PC to update the ESC firmware online.
