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:
“beep-beep-, beep-beep-,beep-beep-”
(Every
“beep-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:
“beep-, beep-, beep- ”(Every “beep-” 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:
“beep-, beep-, beep-” (Every “beep-” 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
“
” 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
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
Plug the throttle signal wires of 4 ESCs (S1 to
S4) into Port #1 to Port #4 of the throttle Hub.
Attention!
In the following picture, t
he pins at the symbol “S” line are the paths of throttle signals
transmission.
Plug the lead at right side into the throttle channel of receiver or fly-control system.
Connect battery to the Quattro ESC.
Calibrate throttle range of the 4 ESCs in the Quattro simultaneously.
b)
To distribute throttle signal to several ESCs
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)
Plug the throttle signal wires of 4 ESCs into Port #1 to Port #4 of the throttle Hub.
Attention!
In the following picture, the pins at the symbol “S” line are the paths of throttle signals
transmission.
Plug the lead at right side into the throttle channel of receiver.
Move throttle stick
to bottom position
and then switch
on transmitter.
Connect battery pack
to ESC, special tone
like
“
123
” means
power supply is OK
When self-test is
finished, a long
“beep-----”
tone
should be emitted
Move
throttle
stick
upwards to go flying
Several
“beep-” tones
should be emitted to
present the amount of
lithium battery cells
