BTK PID reverse error / BTK PID lock error / BTK PID overload error
Error code
- 000321 BTK PID overload error
- 000323 BTK PID reverse error
- 000324 BTK PID lock error
Occurrence condition
- The Belt Tension Release Motor cannot operate due to large motor load
- The Belt Tension Release Motor is rotating in reverse
- The Belt Tension Release Motor cannot rotate
Assumed cause
- When the motor rotates in a direction different from the rotation direction (there was a sudden load abnormality, and the motor rotated in the opposite direction due to the reaction force)
- Power not turn on or motor cannot rotate at all
- The Belt Tension Release Motor load exceeds the expected
Related parts
- Harness polarity wrong
- Belt Tension Release Motor
- The motor load exceeds the expected
- Damage or foreign substances to rotating component part
- MCU Board
- Main Board
- Belt Tension Release mechanism is locked
Troubleshooting
| Step | Confirmation and action | YES | NO |
|---|---|---|---|
| 1 | Check for foreign substances Check the conveyor belt for foreign objects. Is it free from foreign objects or abnormalities? |
Go to step 2 | Remove foreign substances |
| 2 | Check for foreign substances Is it free from foreign objects or abnormalities? |
Go to step 3 | Remove foreign substances If the gear trains are damaged, replace the belt tension release mechanism. |
| 3 | Check for sensor status Check the sensor using the Belt Tension HP Sensor operation check menu. Does the sensor operate normally? |
End | Go to step 4 |
| 4 | Parts replacement Replace the MCU Board and the Main Board, in that order. Is the trouble phenomenon still occurring? |
