Possible Causes

1.  Encoder issue
  • Encoder isn’t under spring tension on the steel.
  • Debris, Dust, or Build up on encoder wheel.
  • Encoder bracket loose.

 

2.  Chain tension
  • Chain tension in gearbox is loose.
  • Loose chains between roller station.

 

3.  Steel gauge adjustment
  • Machine not calibrated for gauge thickness.
  • Incorrect station pressure settings.

Possible resolution

**NOTE** Always have machine off when checking or adjusting encoder

  • Inspect Encoder and confirm there is spring pressure against material.
  • Clean encoder wheel with degreaser.
  • Inspect and adjuster roller station chains.
  • Inspect and adjust gearbox chain tension.
  • Confirm correct gauge calibration has been performed and adjust if required.

Quick Tip

  • Always check encoder spring pressure and that roller is clean of any build up.
  • Verify chain tension before troubleshooting more complex issues.
