13 Double sheet detector
13.1 Overview
Depending on the configuration, the Preset Plus
feeder can be equipped with up to four systems for
double-/multiple-sheet detection.
D Ultrasound double sheet detector
D Double sheet detector in the pull lay (option)
D Bundle detector
D Tear-off detector/multiple-sheet detector (option,
standard with sheeter)
The four systems work independently of each other.
Note
If your press is equipped with an ultra-
sound double sheet detector and a
double sheet detector in the pull lay,
you may switch off either the ultra-
sound double sheet detector or the
double sheet detector in the pull lay.
Switching off both double sheet detec-
tors at the same time is not possible.
13.2 Ultrasound double sheet detector

Fig. 53
The ultrasound double sheet detector protects the
press against damages caused by infed double and
multiple sheets. The ultrasound double sheet detec-
tor is operational after the feeder has been switched
on.
With the exception of multilayer printing materials or
thick foils, the ultrasound double sheet detector rec-
ognizes all standard printing materials.
Switching off the ultrasound double sheet detec-
tor
In order to process special multi-layer printing mate-
rials or thick foils, you may switch off the ultrasound
double sheet detector via the CP2000 Center. After a
job change, the ultrasound double sheet detector
automatically becomes operational again.

double sheet detector can be found in Chapter
