ERR0R_1_1_ Servo motor encoder malfunction
1. If motor does not rotate, the EAC drive board could be the issue.
2. If the motor rotates and ERROR_1_1_ appears, replace the motor speed sensor.
Replace
1. EAC drive board
2. Servo encoder
ERR0R_1_2_
Servo motor thermal sensor is activated; speed is reduced to half speed.
1. Inspect motor temperature. If it is not hot, inspect the thermal sensor cable connection.
2. Inspect walk belt tightness. 3. Inspect walk belt wear.
4. Lubricate the belt. If lubrication is not effective, replace the walk belt..

ERROR_3_1_
Incline motor calibration malfunction
1. Inspect cable connections.
2. After starting the unit, feel the incline motor. If hot, the drive board is malfunctioning.
3. After starting the unit, inspect whether incline 0% switch operates. If so, the drive board is malfunctioning.
 4. Inspect the 0% switch operation.
Replace
1.EAC drive board 2.Incline 0% switch
Power off
Power is off.
1. Re-start the unit as a test.
2. If issue is repeated, replace the EAC drive board.
Replace
1. EAC drive board
ERR0R_4_2_
Low voltage supply
1. Power supply is too low.
2. Measure power supply voltage. If too low, external power supply is insufficient. Please have an electrician address the situation.
3. After fixing the power supply, use the product to confirm its safety.
