IMPORTANT! The ESC named “xxx-xxx-OPTO” does not have a built-in BEC. An UBEC (Ultimate-BEC) or an individual battery
pack should be used to power the receiver. And an individual battery pack is needed to power the program card when setting the
programmable value of such ESCs. Please read the user manual of program card for reference.
Wiring Diagram:
Manual of Sensor less Brushless Motor Speed Controller Ver. HW-01-081027.1
Programmable Items:
Brake Setting：Enabled / Disabled, default is Disabled
Battery Type：Li-xx(Li-ion or Li-poly) / Ni-xx(NiMH or NiCd)，default is Li-xx.
Low Voltage Protection Mode(Cut-Off Mode)： Soft Cut-Off (Gradually reduce the output power) or Cut-Off (Immediately stop the
output power). Default is Soft Cut-Off.
Low Voltage Protection Threshold(Cut-Off Threshold)：Low / Medium / High, default is Medium.

When NOT using balance discharge monitoring and protection function (i.e. Not plugging the balance charge connector
into the BDMP socket on the Guard series ESC, the ESC only monitors the voltage of the whole battery pack )
For lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.6V/2.85V/3.1V. For example: For a 3 cells lithium pack, when “Medium” cutoff threshold is set, the cut-off voltage will be: 2.85*3=8.55V. For nickel batteries, low / medium / high cutoff voltages are 0%/45%/60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 10 cells NiMH battery, fully charged voltage is 1.44*10=14.4V, when “Medium” cut-off threshold is set, the cut-off voltage will be:14.4*45%=6.5V。 When using balance discharge monitoring and protection function (i.e. Plugging the balance charge connector on battery
pack into the BDMP socket on the Guard series ESC, the ESC monitors not only the voltage of the whole battery pack but also
the voltage of each cell). For lithium battery，low / medium / high cut off voltage for each cell is: 2.6V/2.85V/3.1V. When the
voltage of any cell in battery pack is lower than the cut-off threshold, the protection function is activated.
Startup Mode：Normal /Soft /Super-Soft, default is Normal.
Normal is preferred for fixed-wing aircraft. Soft or Super-soft are preferred for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower in comparison, usually taking 1 second for Soft startup or 2 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. This special design is very suitable for aerobatic flight when quick throttle response is needed. Timing：Low / Medium / High, default is Low. Note2
Usually, low timing value can be used for most motors. We recommend the Low timing value for 2 poles motor and medium timing
value for motors with more than 6 poles to get a high efficiency. For higher speed, High timing value can be chosen.
Note2: After changing the timing setting, please test your RC model on the ground prior to flight!
Special Note
Some high KV out-runner motors have very special construction, the space between each magnet is very large, and many ESCs can’t
drive these motors. After much testing, our ESCs have proven to work very well with these types of motors. Some RC enthusiasts still have
several questions about the programming value for these special motors. Therefore, we have provided some suggestions as follows:
Programmable Value Suggestion
Timing Startup
Usually, aircraft use “Normal” startup mode and helicopter use “Super-soft” startup mode Align 420LF (Made in TAIWAN, out-runner) Begin To Use Your New ESC
Please start the ESC in the following sequences:
1.
Move the throttle stick to the bottom position and then switch on the transmitter. Connect the battery pack to the ESC, the ESC begins the self-test process, a special tone “ 123” is emitted, which means the voltage of the battery pack is in normal range, and then N “beep” tones will be emitted, means the number of lithium battery cells. Finally a long “beep------” tone will be emitted, which means self-test is OK, the aircraft/helicopter is ready to go flying.  If nothing is happened, please check the battery pack and all the connections; ” is emitted after 2 beep tones (“beep-beep-”), means the ESC has entered the program mode, it is because the throttle channel of your transmitter is reversed, please set it correctly; If the very rapid “beep-beep-, beep-beep-” tones is emitted, means the input voltage is too low or too high, please check your battery’s voltage. VERY IMPORTANT!

Because different transmitter has different throttle range, we strongly suggest you use the “Throttle Range Setting Function” to calibrate
throttle range. Please read the instruction on page 4------“Throttle Range Setting”.
Alert Tone
Input voltage is abnormal: The ESC begins to check the voltage when the battery pack is connected, if the voltage is not in the acceptable range, such an alert tone will be emitted: “beep-beep-, beep-beep-,beep-beep-” (Every “beep-beep-” has a time interval of about 1 second. ) Throttle signal is abnormal: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-, beep-, beep-”. (Every “beep-” has a time interval of about 2 seconds) Throttle stick is not in the bottom position: When the throttle stick is not in bottom (lowest) position, a very rapid alert tone will be emitted: “beep-, beep-, beep-”. (Every “beep-” has a time interval of about 0.25 second.) Manual of Sensor less Brushless Motor Speed Controller Ver. HW-01-081027.1
Protection Function
1.
Abnormal start up protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In
this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a situation happens in the following cases:
The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)
Over-heat protection: When the temperature of the ESC is over 110 Celsius degrees, the ESC will reduce the output power.
Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further loss for 2 seconds will cause its output to be cut-off completely.
Program Example
Setting “Start Mode” to “Super-Soft”, i.e. value #3 in the programmable item #5
1. Enter Program Mode
Switch on transmitter, move throttle stick to top position, connect battery pack to ESC, wait for 2 seconds, “beep-beep” tone should be emitted. Then wait for another 5 seconds, special tone like “ ” should be emitted, which means program mode is entered.
2. Select Programmable Items
Now you’ll hear 8 tones in a loop. When a long “beep------” tone is emitted, move throttle stick to bottom to enter the “Start Mode” 3. Set Item Value (Programmable Value)
“Beep-”, wait for 3 seconds; “Beep-beep-”, wait for another 3 seconds; then you’ll hear “beep-beep-beep”, move throttle stick to top ” is emitted, now you have set the “Start Mode” item to the value of “Super-Soft” 4. Exit Program Mode
After the special tone “
”, move throttle stick to bottom within 2 seconds.
