3.7.5 Synchronization photocell
The Synchronization photocell enables a high degree of precision in ejecting contaminated material
and counting the product transiting through the unit.
Install the photocell as close as possible to the Metal Detector antenna at the entrance or the exit in
the direction of transit depending on the ejection mode used.
The photocell must be connected to the PHOTOCELL input.
The photocell must be positioned at a height where the beam is always interrupted by the objects transiting on the
conveyor belt.
