Unstable double sheet measurement and error message “SEPARATION: Double sheet counter limit”

Problem:

The sheet is lifted by the front sucker bar but then dropped instead of being pushed into table 1. After 3 times slitter stop and error message “SEPARATION: Double sheet counter limit” appears.

 

Possible Causes & Resolutions:

  • Check on the HMI whether the correct sheet thickness values has been set.
  • Check whether the sheets are sticking to each other or not. If they do, separate the top ones physically from each other and try again to destack them.
  • Check the position / correct function of all separation air nozzles left and right: The top sheets should be visually separated.
  • Check the position / correct function of all separation magnets left and right: The top sheets should be visually separated.
  • If available switch on the separating air between downstacker and 1. table as well, and reset their height if necessary.
  • Check the physical setting height of the double sheet sensor: If the sensor is set too high, he will not be in contact with the sheet, resulting in incorrect measurements.
  • Check the cable between double sheet sensor and control. There may be a cable break which influences the measurement result. Replace the cable if needed.
