Hi sir
The input signal of the mechanical reference sensor (B341) is not registered by SAP- board. The reference point (pulse) is only accepted by the computer if it is in the range of the mechanical switching flag of the reference sensor.- Make a reference run and move the backgauge alongt the entire width of the table, if the position of the mechanical reference point switch has been modified- Check functioning and position of sensor B 341- Check cabling of B341- Verify position values in service menu "machine data"
Good luck p
