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
Check to see if the belt tension release mechanism is locked due to foreign objects or damaged gear trains.

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?
