2. ERROR MESSAGES AND SOLUTIONS

Item

Error Message

Descriptions

UART

CAUSE: Communication timeout.

SOLUTION:

a. Check if PIN3 and PIN4 of the upper board are connected properly or

the loose contact.

b. Restart the treadmill to re-establish communication. If the error

message occurs again, please replace the upper board or the lower

board.

U-01

CAUSE: Lower board model is not matched.

SOLUTION: Restart the treadmill to re-establish communication. If the

error message occurs again, please replace the upper board or the

lower board.

U-02

CAUSE: Upper board and lower board are not matched.

SOLUTION: Check if the version of lower board is correct. Restart the

treadmill to re-establish communication. If the error message occurs

again, please replace the upper board or the lower board.

U-03

U-04

CAUSE: Lower board writing fault.

SOLUTION: Restart the treadmill and re-write the parameter to lower

board. If the error message occurs again, please replace the lower

board.

U-05

CAUSE: Lower board reading fault.

SOLUTION: Restart the treadmill and re-establish communication. If the

error message occurs again, please replace the lower board.

DC-1

CAUSE: The input voltage is too low.

SOLUTION: Restart the treadmill to clear this error message. If the error

message still pops out, please measure and improve the input voltage.

DC-2

CAUSE: Electric voltage is overload.

SOLUTION: Restart the treadmill to clear this error message.

DC-3

CAUSE: The input voltage is too high.

SOLUTION: Restart the treadmill to clear this error message. If the error

message is still pop out, please measure and improve the input voltage.

DC-4

CAUSE: Current overload.

SOLUTION: Restart the treadmill.

Descriptions

10.

DC-5

CAUSE: Over current failure.

SOLUTION: Restart the treadmill.

11.

DC-6

CAUSE: Lower board failure.

SOLUTION: Replace the lower board.

12.

DC-7

CAUSE: During the operation, IGBT short circuit to protect lower board.

SOLUTION: Restart the treadmill and the error message “DC-6” pops

out. (It means the lower board needs to be replaced.)

13.

DC-8

CAUSE: The emergency stop button of the treadmill is loose contact.

Therefore the display of the upper board is normal but the operation of

lower board is interrupted.

SOLUTION: Check the wiring of emergency stop button. Make sure the

wiring between upper board and lower board is normal. If wiring is

normal, please replace the upper board or the lower board.

14.

CAUSE: Motor sensor failure.

SOLUTION:

Check if the motor is running normally.

- If not, please replace lower board or motor.

- If the motor runs normally, please check if the position of RPM sensor

and magnetic induction are correct.

15.

CAUSE: Incline motor doesn't reach the assigned position in limited

time within the mechanism safe range.

SOLUTION:

1. The variable resistor power supply (+) of incline motor is

disconnected.

2. The incline ADC circuit is damaged.

3. The incline motor movement is malfunction (stop or turn to wrong

side).

16.

CAUSE: The ADC value of incline motor is incorrect, and out of the

mechanism safe range.

SOLUTION:

1. The variable resistor power supply (－) of incline motor is

disconnected.

2. The incline motor movement is out of the mechanism safe range (too

high or too low).
