ESC SR100A Manuel utilisateur
SR100A Speed Controller
V2.0
Dear customer,
Congratulations on the purchase of your new Phoenixtech SR Series Brushless ESC. This
latest series of controllers is unique in that it is equipped with a robust internal switching
Battery Eliminator Circuit (BEC) that allows the use of up to 6 lithium polymer cells in
series without the need for an external BEC. This internal BEC delivers 5.2 volts to your
receiver and servos and is capable of delivering a continuous 3 Amps of current, 4 Amps
peak.
Please read and pay careful attention to the following instructions before you start
to work with your motor and controller. These instructions contain important
programming information that can keep you from ruining your motor, batteries,
and ESC. Model aircraft can cause serious injury and destruction of property. This
is not a toy!
Your SR Series controller is equipped with a ferrite ring “choke” to minimize
interference. Depending on your radio system, you may or may not need this
device. It is easily removed by unwrapping the wire from around the ring. Always
range check your flight system on new aircraft with the motor running before
flying.
Wire Connections:
Motor Connections - The speed controller can be connected to the motor by soldering the
3 wires directly or with high quality connectors. Always use new connectors, which
should be soldered carefully to the cables and insulated with a heat shrink tube.
Battery connections – Solder the connectors of your choice on to the red and black
battery wires. The red wire corresponds to battery (+) and the black wire to battery (-).
Reversing the battery connections will destroy the ESC. The maximum length of the
battery pack wires should be 6 inches.
Receiver connection – Plug the “JR” connector into the receiver throttle channel.
Installing the Controller:
Install the controller in the model so that it is free from vibration and shock, using Velcro
or double sided foam tape. Make sure there is sufficient cooling for the controller by
ducting air through cooling holes from outside airflow. Failure to do this could cause
controller shutdown or damage. Mount the BEC switch securely.
Transmitter set up:
Check that throttle end point settings are +/-100%.
For Futaba transmitters, reverse the throttle channel.
Normal start up:
Switch the transmitter on and pull the throttle stick down to idle position.
Connect battery pack to the controller
Turn receiver switched “On” (BEC switch on).
You will hear one tone for Brake on or two tones for Brake off.
The position of full throttle will be calibrated automatically.
You motor now is ready to run.
SAFETY WARNING:
zAlways connect the motor battery pack just before flight and disconnect it
immediately after landing. The battery will be drained if left connected.
zOnce the motor battery pack is connected, handle the model with extreme care!

zEnsure that you are well clear of the propeller at all times.
zA rotating propeller is extremely dangerous!
zEven when the receiver (BEC) switch turned “OFF”, the motor battery pack may
still be connected. Handle the model with extreme care and stay clear of the
propeller!
The controller comes programmed with the following factory default settings:
Brake : Off Lets the propeller coast
Battery type : Li-Poly Auto-Detect Auto detect Cells No.
Soft start : Enable Accelerates motor slowly
Low Voltage Cutoff : Reduce power Slow motor when battery is low
Timing : Auto ESC advance timing mode
Frequency : 8KHz ESC switching frequency
RPM Control : Off Governor mode for helicopters
How to program your controller:
The ESC is programmed by using the transmitter throttle stick as directed below and
responding to the tones produced by the motor. The tones are played in the order below.
Responding to a tone with the throttle stick changes a setting.After making a change,
disconnect the battery. Start over to make another change. To leave programming mode
without making a change, disconnect the battery from the ESC.
zREMOVE PROPELLER
zSwitch on the transmitter and push throttle stick to full throttle.
zConnect the motor battery pack and turn on the receiver (BEC) switch.
zWait for 5 seconds, you’ll hear __ -- (two low tones followed by two high tones)
zSetup mode is entered
zWhen you hear the desired tones from below, pull the throttle down, you will hear
two confirmation tones. The setting is now memorized.
zYou can only change one setting at a time, if you need to change more settings,
disconnect the battery from the ESC and wait 5 seconds, and repeat the above
procedure for the next setting.
zYou can exit the programming mode at any time if you disconnect the battery from
the ESC.
1. Setting up the propeller Brake on or off
Follow above procedure to enter the programming mode.
If you pull the throttle stick to off within 5 seconds, Brake will be changed. (ON ÆOFF,
or OFF ÆON)
When you connect the battery to get ready to fly, you will hear one tone for Brake on or
two tones for Brake off.
2. Battery type
(Select battery type that is being used in your model)
NiCad: (50% of initial voltage)
. . . . . (5 single beeps)
Auto detect LiPo (3.0V/Per)
.. .. .. .. .. (5 double beeps)
3. Rotation reverse
This function is to change the motor rotation direction.

(For example: Right to Left, or vice versa)
Reverse motor rotation
W W W W W (5 double warble tones)
4. Soft start (Acceleration)
When a gearbox is used, it’s highly recommended to enable the soft start feature
to protect the gearbox, especially when large diameter propellers are used.
Disable the soft start function when direct drive is used or for speed competition.
Enable:VV VV VV VV VV (5 dual warble tones)
Disable: V V V V V (5 single warble tones)
5. Low Voltage Cutoff (LVC)
If the motor battery pack drops to the programmed cut-off voltage, the controller will
either ignore, reduce the motor speed or stop the motor to ensure that there is enough
power for the receiver and servos. You can resume normal operation by pulling down the
throttle stick and pushing it up again, but remember that it’s time to land your model!
Ignore
(Motor won’t stop until battery IS DRAINED)
_-- _-- _-- _-- _-- (single low tone followed by dual high tone)
Reduce power:

_- _- _- _- _- (single low tone followed by single high tone)
Cut off:
(Stop motor – Motor can be restarted by moving throttle stick down to idle position)
-_ -_ -_ -_ -_ (single high tone followed by single low tone)
6. Timing (advance timing)
The controller has three timing modes; Automatic works perfect for ALL types of brushless
motor. For some brands or homemade brushless motors, you have to set the right timing for
optimal efficiency and power; 7 degree for multi-pole motors, 30 degree for out runner motors.
Automatic: (7 ~ 30 degree)
- - - - - (five short tones)
LowAdvance: (7 degree)
-- -- -- -- -- (five double short tones)
High Advance (22 ~ 30 degree)
--- --- --- --- --- (five triple short tones)
7. Switching Frequency
The controller has two switching frequencies. 8KHz is good forALL types of two pole motors,
16KHz is good for multi pole motors.

Caution! Warning!:
Model aircraft equipped with high power motors can kill. High power motor systems can be very
dangerous! High currents can heat wires and batteries, causing fires and burning skin or anything.
Follow the wiring connection carefully!
Always fly at a sanctioned field. Never fly over or near spectators. Even though this controller is
equipped with a safety arming program, you should still use caution when connecting the
battery.
Notice for Operation:
•Do not exceed 16 NiCad NiMh cells or 5S Li-Poly cells in series.
•Temperature overload protection is built into the speed controller, it turns off the motor
immediately when the temperature reaches 212°F/100°C.
•Do not connect the controller to just ‘any’kind of power sources. Take care to ensure that
the right polarity of NiCad, NiMh or Li-Poly power packs.
•The controller will be destroyed if connected to the battery with the wrong polarity.
