Operation with ejector activation for the ejection of contaminated material.
In CEIA Integrated Systems fitted with an ejector, this mode determines the automatic ejection and
removal of the contaminated material in the reject bin.

ED: Ejection distance
In free-falling applications, or whenever the immediate activation of the ejection after an alarm is required, set ED=0.
Set ET at the minimum value that grant the correct removal of the contaminated material.
In applications at high trasnport speed, where the ejection activation time is not negligible, it is possible to anticipate its
activation through the parameter ERT.
THS-RB systems
The ejection signal is sent to the checkweigher that will manage the ejection itself.
In this case set EM=F and ED=0.
