Stop the controller to enter failure state. It can not be started up. The
electronic meter displays the error code and the buzzer sounds for 3
times.
Possible reasons: There is interference between the controller and the
electronic meter. Check all the wires that connect the controller and the
electronic
meter. Make sure that all wirings are properly connected and that there
is no damage to them.
1.check if the motor wire is well connected to the controller.

2.Stop and enter the failure state. The electronic meter buzzer sounds
for 9 times and the error code is displayed. No display at other areas. If
the system enters into standby state after about 10s of failure state,
restart can be conducted.

Possible reasons: If speed sensor signal is not received for more than
3s, check whether the sensor connector is well plugged or whether it is
damaged; plug it well or replace the sensor.

some place of the treadmill is jammed so that the motor can not rotate;
thus, the system start up self-protection against excessive current under
excessive load; adjust the treadmill and restart it. Besides, check
whether there is over-current sound or burning odor when the motor is
running; replace the motor; check whether the controller emits abnormal
odor; replace it if yes; check whether power supply voltage
specifications is inconsistent or too low and use correct voltage
specifications for re-test.
