for any damages, losses or costs resulting from the use of the product. Any claims arising from the operating, failure or malfunctioning etc. will be
denied. We assume no liability for personal injury, property damage or consequential damages resulting from our product or our workmanship. As far
as is legally permitted, the obligation to compensation is limited to the invoice amount of the affected product.

˖ Soft Cut-Off (Gradually reduce the output) /Cut-Off (Immediately stop the output)

4.

Low Voltage Protection Threshold (Cut-Off Threshold)

˖Low / Medium / High

a)

For lithium battery, the battery cell amount is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For
example: For a 3S Lipo battery, when

³Medium´ cutoff threshold is set, the cut-off voltage will be: 3.15*3=9.45V

b)

For NiMH battery, low / medium / high cutoff voltages are 0% / 50% / 65% 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 6 cells NiMH battery, fully charged voltage is 1.44*6=8.64V

ZKHQ³Medium´FXW-off

threshold is set, the cut-off voltage will be 8.64*50%=4.32V

Warning! In order to protect the expensive multi-rotor, the default settings (i.e. Battery Type

protection even if the Lipo battery is over discharged. If you do need to activate the battery protection function please change the default settings.

5. Startup

Mode

˖Normal /Soft /Super-Soft (300ms / 1.5s / 3s)

The initial acceleration of the Soft and Super-Soft modes are slower than the Normal mode, it takes 1.5 second for Soft startup or 3 seconds for Super-Soft
startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick
moved to top position) within 3 seconds after the first startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash
caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.

6. Timing

˖Low / Medium / High,( 3.75e/ 15e/ 26.25e)

Usually, the default timing is suitable for most motors. To get higher speed, High timing can be chosen.

Begin To Use Your New ESC
Because different transmitters / flying control systems have different throttle ranges, please calibrate the throttle range for each speed controller before flying.
The Throttle Signal HUB is recommended for calibrating the throttle ranges for 4 speed controllers simultaneously instead of one by one.

Throttle range setting:
Note:
The throttle range of each speed controller in the Quattro should be set separately. When the Quattro is installed in a multi-rotor, you should set the throttle
range of each ESC via the flying control system.






Normal startup procedure:


Protection Function
1.

Start up failure protection: If the motor failed to start within 2 seconds of throttle application, the ESC would cut-off the output power. In such a case, the
throttle stick MUST be moved to the bottom position 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, etc.)

2.

Over-heat protection: When the temperature of the ESC is higher than 110 Celsius degrees, the ESC will reduce the output power.

3. Throttle

signal

loss

protection: The ESC will reduce the output power if the throttle signal is lost for 1 second, further loss for 2 seconds will cause the output

to be cut-off completely.

Trouble Shooting

Trouble

Possible Reason

Action

After power on, motor doesn

¶t work, no sound is

emitted

The connection between battery pack and ESC
is not correct

Check the power connection.
Replace the connector.

After power on, motor doesn

¶t work, such an alert tone

is emitted:

³beep-beep-, beep-beep-,beep-beep-´(Every

³beep-beep-´ has a time interval of about 1 second)

Input voltage is abnormal, too high or too low.

Check the voltage of battery pack

After power on, motor doesn

¶t work, such an alert tone

is emitted:

³beep-, beep-, beep- ´(Every ³beep-´ has a

time interval of about 2 seconds)

Throttle signal is abnormal.

Check the receiver / transmitter / flying controller
Check the cable of throttle channel

After power on, motor doesn

¶t work, such an alert tone

is emitted:

³beep-, beep-, beep-´ (Every ³beep-´ has a

time interval of about 0.25 second)

The throttle stick is not in the bottom (lowest)
position

Move the throttle stick to bottom position

After power on, motor doesn

¶t work, a special tone

³

´ is emitted after 2 beep tone (beep-beep-)

The Direction of throttle channel is reversed, so
the ESC enters the program mode

Set the direction of throttle channel correctly

The motor runs in the opposite direction

The connection between ESC and the motor
need to be changed.

Swap any two wire connections between ESC
and motor

Program ESC With Transmitter (4 Steps)























NOTE:
1.

Each speed controller in the Quattro must be programmed separately.

2.

Please make sure the settings for each speed controller in the Quattro are same.

Accessory: Throttle Hub (Throttle Hub is a standard accessory for Quatrro ESC)

1.

Applications of Throttle Hub
a)

Use this throttle Hub to calibrate the throttle range for the Quattro ESC
( The Quattro is an equipment in quadcopter, usually it has 4 ESCs in
1 board);

b)

Use this throttle Hub as throttle signal distributor for several speed
controllers (1 ESC to 4 ESCs).

2.

Operations of Throttle Hub

a)

To calibrate the throttle range for the Quattro ESC
z

Plug the throttle signal wires of 4 ESCs (S1 to S4) into Port
#1 to Port #4 of the throttle Hub.
Attention!

z

Plug the lead at right side into the throttle channel of receiver or fly-control system.

z

Connect battery to the Quattro ESC.

z

Calibrate throttle range of the 4 ESCs in the Quattro simultaneously.

b)

To distribute throttle signal to several ESCs
z

Generally, in case of throttle signal distribution, only one ESC has its built-in BEC enabled (or reserved), the BECs in other ESCs must be
disabled (That is, cut the red wires in the Rx cables)

z

Plug the throttle signal wires of 4 ESCs into Port #1 to Port #4 of the throttle Hub.

be emitted, means the
lowest point of throttle
range has been correctly
confirmed
