E-flite 30-Amp Pro Switch-Mode BEC Brushless ESC - Manual (Page 2)

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 74% cutoff,
followed by 3 rising tones to indicate the controller is armed.
3. When you move the throttle stick upward, the motor will run. Continue
to move the throttle stick upward to the full throttle (high) position,
and the motor will run faster. When the throttle stick goes below the
start-up position, the motor will stop running.
4. Check servo motion as part of your preflight check. It is very
important to 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-flite 30-Amp Pro
ESC are as follows:
• Voltage cutoff set at 74%
• 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, first 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 specific
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 74% 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 first selection again.
IMPORTANT NOTE ABOUT 74% CUTOFF: This option will activate the soft
cutoff at 74% of startup voltage or 9.2V, whichever is higher. For example,
if your pack measures 16.8 volts at startup, then the soft cut will occur at
12.4 volts. The 74% 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 LiPo batteries if you are using the
74% 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 LiPo battery pack, and to prevent sudden power loss.
Programming Menu 2 – Brake Type
The default setting is Brake Off. This option gives you the choice to have
the ESC stop the propeller during flight (Brake On) or allow it to windmill
(Brake Off). Use the Brake On options for folding propellers.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 2 times, indicating you are now in Menu 2.
2. Move the throttle stick to full throttle (>1.7ms) position to
make changes to the Brake Type programming.
a. To select No Brake/Brake Off – You will hear 1 short beep.
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 Soft Brake – You will hear 2 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 Medium Brake – 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.
d. To select Hard Brake – 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 first selection again.
Programming Menu 3 – Timing
The default setting is 15 degrees. As a general rule, lower pole count
motors use lower timing and higher pole count motors use higher timing.
Please refer to your motor instructions and specifications for an indication
of the number of poles.
LOW TIMING ADVANCE
Timing Degrees – 5 & 10
Motor Poles – 2 to 4
Expected Performance – Good balance of power and efficiency
Motor Poles – 6 or more
Expected Performance – Best efficiency and run time (lowest power)
STANDARD TIMING ADVANCE
Timing Degrees – 15 & 20
Motor Poles – 6 to 12
Expected Performance – Good balance of power and efficiency
Motor Poles – 14 or more
Expected Performance – Best efficiency and run time (lowest power)
HIGH TIMING ADVANCE
Timing Degrees – 25
Motor Poles – 12
Expected Performance – Highest power, less efficiency
Motor Poles – 14 or more
Expected Performance – Good balance of power and efficiency
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 3 times, indicating you are now in Menu 3.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the Timing programming.
a. To select 5 Degrees – You will hear 1 short beep. 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.
