Operation with ejection activation synchronized by photocell (i.e. halting of the transport system),
manual elimination of the contaminated material and manual reset by the operator.
On CEIA Integrated Systems this mode determines the stop of the conveyor belt.

ED: Ejection distance
PD: Photocell distance
After an alarm, the Metal Detector does not check if there are any other metallic fragments in the material immediately
following.
This means that you must remove all the material between the Probe entrance and the removal area
.
To minimize waste of material it is advisable to select a low setting for the ED parameter.
After an alarm, if the conveyor belt is stopped, pressing STOP or one of the transport system emergency buttons before
the contaminated material has reached the predefined stop position means the Metal Detector will remain in alarm status
and cannot be reset until the belt is restarted, allowing the contaminated pack to reach the predefined stop position.
