3.1.2.5 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 Detection Probe at the entrance or
the exit in the direction of transit depending on the ejection mode used (see paragraph 3.8.8).
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. It is also recommended to place it at the minimum possible distance from the Probe side and sufficiently
set back with respect to the transit tunnel, according to the free metal zone indicated on paragraph 3.1.2.2 (expecially
when it has a body or other elements made of metal).
