E1
Abnormal
communication
between the controller
and the electronic
console after powering
on.
Stop the controller to enter failure state. It cannot be started up.
The electronic meter displays the error code and the buzzer
sounds for 3 times.
Possible reasons: The communication between the controller
and the electronic meter is blocked; check each section of
connection of the communication wires from the electronic meter
to the controller and ensure that all core wires are well
connected. Check whether wires between the electronic meter
and the controller are damaged; if yes, replace the damaged
wire.
E2
Controller can’t detect
the voltage of motor:
No speed sensor signal
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.
3. 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 recovering to the normal state and enter into the
standby state after stop, normal startup can be implemented.
Possible reasons: Check whether motor wires are well
connected; re-connect motor wires. Check whether the controller
emits abnormal odor; replace it if yes.
E5
Over current protect：
Under running, current
of DC motor big than
rated current +6A for
more than 3 seconds.
1. To check if there is oil between running belt and running board.
If not, add 15ml lubrication oil.
2. Some part of treadmill is stuck to cause the motor can’t run.
3. To check if there is burnt smell from motor, replace it.
4. To check if there is burnt smell from under control board,
replace it.
E6
Explosion-proof
protection: abnormal
power voltage or motor
abnormality leads to the
damage of driving
motor circuit
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 recovering to the normal state and enter into the
standby state after stop, normal startup can be implemented.
Possible reasons: Check whether the power supply voltage is
less than 50% of the normal value; please ensure correct voltage
and test again; check whether the controller emits the odor of
burning; if yes, replace the controller; check whether motor wires
are well connected; re-connect motor wires.
E7
Safety lock not in
position
Put Safety lock in position;
Change Safety lock switch and reconnect Safety lock line
