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.

Problem:

Suction cup malfunction.
Vacuum not working, constantly on or constantly blowing air instead of (sucking and then blowing) once only.

Possible Causes & Resolutions:

• Most likely a relay is defective and needs to be replaced.
• Vacuum suction injector is defective and needs to be replaced.

Components:

KA1.2-1.7 Relays

Y108 Vacuum blank feeder back
Y109 Vacuum blank feeder front
Y110 Vacuum 1.Table

Y111 Blow off blank feeder back
Y112 Blow off blank feeder front
Y113 Blow off 1.Table

Possible cause:

• The reed sensor B233 on the vertical cylinder rear/right corner is not correctly adjusted.
  • when piston of cylinder remains in bottom position (due to blank magazine clearing process), the reed switch must be active
