Generic example
S: Metal Detector Probe
N: Conveyor belt
C: Contaminated pack
DW: Detector width
ED: Ejector 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.
In free-falling applications, or whenever the immediate activation of the ejection after an alarm is required, set ED=0.
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.
