Speed sensor has no
signal: controller PCB
has voltage output to
E3
DC motor, but can not
receive motor speed
feedback for more
than 3 seconds.
Overcurrent
protection: in
E5 operation, the DC
motor current is more
than 3 seconds longer
than the rated current.
Flameproof
protection: abnormal
power supply voltage
E6
or abnormal motor
cause damage to
drive motor circuit.
Indicates that the
E7
console did not detect
a security lock signal
1. Check if the motor line is firmly connected to controller.
2. Shutdown into the error state, console buzzer beeps 9
times, at the same time console displays error code, the other
area does not show message. Maintain error state after about
10 seconds into standby state, can restart.
Possible cause: in 3 seconds without detecting the speed
sensor signal, check if sensor plug is not plugged in or
damaged, plug it or replace the sensor.
3. Shutdown into the error state, console buzzer beeps 9
times, at the same time console displays error code, the other
area does not show message. If it returns to normal after
shutdown, you can enter standby state, normally can start.
Shutdown into the error state, console buzzer beeps 9 times,
at the same time console displays error code, the other area
does not show message. Maintain error state after about 10
seconds into standby state, can restart.
Possible causes: over rated load leads to excessive current,
system self-protection, or a part of the treadmill is stuck,
resulting in the motor can not rotate, overload, excessive
current, the system self-protection; adjust the treadmill to run
again. Or, please check if the motor is running with overcurrent
sound or if there is charred smell, to replace the motor, or to
check whether the controller PCB is charred, to replace the
controller PCB, or to check whether the power supply voltage
specifications are not in accordance with or too low. Re-test
under the correct voltage specifications.
Possible causes: check if the power supply voltage is less than
50% of the normal voltage, please use the correct voltage
specification to re-test; check the controller PCB for odour,
replace the controller PCB; check whether the motor line is
connected, reconnect the motor line.
Magnetron damage, Check if magnetron installation position is
correct, if magnets are well placed.
