Operation with ejection cycle activation, synchronized by photocell, for the automatic ejection of the
single contaminated pack.
In CEIA Integrated Systems fitted with an ejector, this mode determines the automatic ejection and
removal of the contaminated material in the reject bin. For this systems it is recommended to set a
transit speed lower than 60 m/min.

Generic example
S: Metal Detector Probe
N: Conveyor belt
E: Ejector
F1: Synchronization photocell
F2: Ejection check sensor
PL: Pack length

THS-RB systems
The ejection signal is sent directly to the ejector. In this case all conveyor sections must have the
same speed and their start must be synchronized. Parameters values can be set as indicated in
paragraphs describing other conveyor belt types.
