2. Throttle Range Setting (Throttle Range Calibration)
In order to make the ESC fit the throttle range, you must calibrate it for the following cases; otherwise the ESC
cannot work properly.
1) Begin to use a new ESC;
2) Begin to use a new transmitter;
3) Change the settings of neutral position of the throttle stick, ATV or EPA parameters, etc.
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.
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.
Note3: The “SET” key of EZRUN-18A-SL is beside the main switch of the controller.
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.
【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 lithium 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
lithium 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 3 cell lithium battery pack; If it is lower than 9.0V, it will be considered as a 2 cell
lithium battery pack. For example, if the NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, so it
will be considered as a 2 cell lithium battery pack, 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.
【TROUBLE SHOOTING】
【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
battery pack more than 6 cells of NiMH. It is located on the heat sink of the ESC, it
helps to cool the ESC with downward airflow. The picture on the right side shows
the installation.
WARNING! Please note the original fan (5V) combined with the ESC can
ONLY work with a 2 cells lithium battery pack or 4-6 cells NiMH battery pack.
Please NEVER use it with a 3 cells lithium battery pack or NiMH battery pack
more than 6 cells, otherwise it may be destroyed.
Please check the label of the fan carefully to confirm its working voltage
before using it.
2. Program card (Digital LED Display).
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. When the programmable value
needs to be changed, please just plug the control wires of the ESC (trio wires with
black, red and white color) into the socket of the program card (The socket is on
the right corner, and marked with ), and then connect the main battery pack
to the ESC, each item
’s value will be shown on the program card. Use “ITEM” and
“VALUE” buttons to select the programmable items and new values, and then
press
“OK” button to store the new settings into the ESC.
3. Advanced 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
can also work as an USB adapter to connect the ESC with a PC to update the ESC firmware online.
Trouble Possible Reason Solution
After power on, motor can ’t work, no
sound is emitted
The connections between
battery pack and ESC are not
correct
Check the power connections
Replace the connectors
After power on, motor can’t work, but
emits “beep-beep-, beep-beep-” alert
tone. (Every “beep-beep-” has a time
interval of 1 second )
Input voltage is abnormal, too
high or too low.
Check the voltage of the battery
pack
After power on, motor can’t work, but
emits “beep-, beep-, beep-” alert tone.
(Every “beep-” has a time interval of
about 2 seconds)
Throttle signal is abnormal Check the transmitter and the
receiver
Check the wire of the throttle
channel
The motor runs in the opposite direction The wire connections between
ESC and the motor need to be
changed
Swap any two wire connections
between the ESC and the motor.
The motor suddenly stops running
while in working state The throttle signal is lost Check the transmitter and the
receiver
Check the wire of the throttle
channel
The ESC has entered the Low
Voltage Protection Mode Replace the battery pack
Random stop or restart or irregular
working state Some connections are not
reliable Check all the connections: battery
pack connections, throttle signal
wire, and motor connections, etc.
There is strong Electro -
Magnetic interference in flying
field.
Reset the ESC to resume normal
operation. If the function could not
resume, you might need to move to
another area to run the car.
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. (
*Note3 )
(Please refer to 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.
