Blink Codes for Lower Motor Control Board 1000111476
| Number of LED Blinks | Status | Description | Possible Problem Component |
|---|---|---|---|
| 1 | Works normally | Works normally | - |
| 2 | Optical Encoder without feedback | The optical encoder is without feedback for 3 seconds during start procedure or 1 second during workout. | Poor contact or ** Motor not running will trigger this code as well. |
| 3 | Overload | The motor current is over rated tor more than & seconds | Motor |
| 4 | Speed is too large | The motor power components are damaged or speed up too fast. | Motor ** Could result from blown Mosfet. |
| 5 | The safety key is off | The safety key is off. | Safety Key |
| 6 | The incline motor is stuck or has lost efficiency | There is no signal to the MCB when the incline motor is energized. | Incline Motor |
| 7 | Communication abnormal | No or abnormal communication between the console and MCB. | Console Cable, UCB, or MCB |
| 8 | Bad connection between the incline motor and the MCB | The incline motor cannot go back to absolute "O" degrees. | Incline Motor or MCB |
