ESC Operation/Startup
Starting Your Power System
1. Turn on your transmitter and ensure the position of the
throttle stick is set to Idle/Off.
2. Plug the battery pack into the controller. You will hear
1 low long tone to indicate startup, then the respective
number of medium-length mid tones to indicate the cell
count or a musical tone for the 70% cutoff, followed
by 3 rising tones to indicate the controller is armed.
3. When you move the throttle stick upward, the motor will
run. If you continue to move the throttle stick upward
to the full throttle (high position), the motor will run
faster. If you lower the throttle stick below the start-up
position, the motor will stop running.
4. Check servo motion as part of your prefl ight check.
It is very important you make sure linkages are free-
moving with no binding.
Remember, when in the programming mode:
Full Throttle = Stick Up
Idle = Stick Down
The default settings (from the package) for your E-fl ite
40-Amp Pro ESC are as follows:
• Voltage cutoff set at 70%
• Brake set to Off
• Timing set at 15 degrees
• Throttle Input Range set at 1.2ms to 1.8ms
• Start-up Rate (Acceleration Delay) set at 0.25 seconds
• PWM Frequency set at 8kHz
• Operating Mode set to normal (airplane)
Entering the Programming Mode
1. With the battery disconnected from the controller, and
the transmitter turned on, fi rst move the throttle stick
to full throttle (>1.7ms) position. Leave it in this position
and then connect the battery to the controller.
2. Wait for 5 seconds, and the ESC will give two sets of
fast ringing tones to indicate you have successfully
entered the programming mode.
3. Once you hear these tones, move the stick to center
(between 1.4 and 1.7ms) for 5 seconds, and the controller
will beep 1 time, indicating you are now in Menu 1.
4. The controller will now wait 5 seconds for you to make
your selection; your programming options are either
full throttle (>1.7ms) or idle (<1.3ms).
5. When you have made a valid selection, the control will
beep once with a lower tone, and you can move the
stick back to center for the next menu item (2 beeps,
3 beeps and so on). If you do not make a selection
within 5 seconds, the controller will move to the next
menu item.
6. If you want to make changes in the programming menus
(see specifi c instructions below) move the throttle stick
to full throttle (>1.7ms) position. You will have 5 seconds
to make your selection.
7. If you want to advance to the next menu, allow the
programming to skip to the next menu after the 5
seconds have expired.
Programming Menu 1 – Voltage Cutoff
Use this option to set the voltage at which the controller
will shut down the motor to prevent damage to your battery
when it reaches the cutoff voltage. You will know your
battery pack has reached auto cutoff when you hear the
motor “pulse” repeatedly.
1. Move the throttle stick to full throttle (>1.7ms) position
to make changes to the voltage cutoff programming.
a.
To select 3-cell low voltage cutoff – You will hear
3 short beeps. Move the throttle stick to center
(between 1.4 and 1.6ms). The controller will beep 2
times, indicating you have set the program selection
or leave in full throttle for 5 seconds to advance to
the next selection.
b.
To select 4-cell low voltage cutoff – You will hear
4 short beeps. Move the throttle stick to center
(between 1.4 and 1.6ms). The controller will beep 2
times, indicating you have set the program selection
or leave in full throttle for 5 seconds to advance to
the next selection.
c.
To select 5-cell low voltage cutoff – You will hear
5 short beeps. Move the throttle stick to center
(between 1.4 and 1.6ms). The controller will beep 2
times, indicating you have set the program selection
or leave in full throttle for 5 seconds to advance to
the next selection.
d.
To select 6-cell low voltage cutoff – You will hear
6 short beeps. Move the throttle stick to center
(between 1.4 and 1.6ms). The controller will beep 2
times, indicating you have set the program selection
or leave in full throttle for 5 seconds to advance to
the next selection.
e.
To select 70% cutoff – You will hear 7 short beeps.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating
you have set the program selection or leave in
full throttle for 5 seconds to advance to the fi rst
selection again.
IMPORTANT NOTE ABOUT 70% CUTOFF:
This option
will activate the soft cutoff at 70% of startup voltage.
For example, if your pack measures 15.0 volts at startup,
then the soft cut will occur at 10.5 volts. The 70% cutoff
option will check the startup voltage every time you plug
the battery into the controller, so beware of using partially
charged packs, as the system cannot protect your Li-Po
batteries if you are using the 70% cutoff and connect a
partially charged pack. You will know your battery pack
has reached soft auto cutoff when you hear the motor
“pulse” repeatedly. We recommend you land your model
as soon as you hear the motor pulse (indicating the pack
voltage has dropped to the cutoff voltage level) to prevent
over-discharge of the Li-Po battery pack, and to prevent
sudden power loss.
