TROUBLESHOOTING
Problem
Potential reasons
Solutions
-------
Safety key falls down
1. Place back the safety key back;
2. Replace safety key switch or magnetic sensor in the electronic
meter; if the problem still fails to be solved, replace the electronic
meter;
E01

Communication failure from the
electronic meter to the driver,
The electronic meter displays
E01 in the operating process
Communication failure from the
driver to the electronic meter
1. Check whether the connecting joint between the electronic meter
and the core wire of the controller is loose; whether wires are
damaged; whether the core wires are in correct connecting order.
2. The controller may be defective. Check and replace with a good
one.
3. The electronic controller’s IC may not be plugged to the place.
Check and ensure it is plugged in well.
4. The transformer may be damaged. Check and replace with a good
one.
E02
Explosion-proof protection or
motor abnormality
1. Check whether the power supply voltage is less than 50% of the
normal value; please ensure correct voltage and test again;
2 Check whether motor wires are well connected; re-connect motor
wires, or, if the problem still fails to be solved, replace the motor;
3. Check whether there is peculiar odor generated by the controller; if
yes, it means that IGBT has been broken down to cause short circuit;
then, replace the controller.
E03
No sensory signal
Check whether the photoelectric sensor directs to the hole on CD;
check whether wires of photoelectric sensor are damaged and
whether terminals of the photoelectric sensor and speed terminals on
the controller are firmly connected.
E04
Lifting learning or
self-inspection fails
1. Check whether motor signal wires are well inserted; re-insert the
signal wire joint to ensure that it is reliable;
2. Check whether lifting motor's AC wires are properly connected;
lifting motor shall be correctly plugged according to marks on its AC
controller;
3. Check whether motor wiring is damaged to form open circuit; if yes,
replace wires or replace the lifting motor;
4. Replace the controller;
5. After all of these inspections, press the learning key for learning
again.
E05
Over-current protection
1. It may be the system’s self-protection against excessive current
when the load exceeds the rated value; restart the machine;
2. Some part of the treadmill is jammed so that the motor cannot
rotate, thus triggering the self-protection of the system against
excessive current under excessive load; adjust the treadmill and
restart it, or add lubricant.
3. Check whether there is over-current sound or burning odor when
the motor is running; replace the motor;
4. Check whether the controller emits the odor of burning; if yes,
replace the controller.
