Operation process

  1. After loading the paper roll and finishing the material feeding job.
  2. Press the CENT button, and the unwind stand will return to the middle position.
  3. Choose detect sensor mode I/II. Choose II, because the DOINMC machine adopts an ultrasonic sensor.
  4. Choose P/N. It controls the drive motor’s movement direction. Move to the machine operation side or move to the machine transmission side.

Inspection steps:

  1.  If you choose P mode, the sensor detects the material operation side shifting, and the drive motor guides the material to the transmission side moving. If this situation happens, that means you choose the correct mode.
  2. If the sensor detects material operation side shifting, the drive motor also moves towards the operation side. Please press the P/N button to let the material move to the transmission side.  And incidcation light will flash.
