Ejecting Accepted Products
This operation enables the SELECTOR output (output BIT1) every
accepted
product
(instead of rejected). This configuration is the outcome of the following
settings:
parameter SELECTOR in CONFIGURATION on DEVIATOR 1;
parameter SELECTOR in PLU on DEVIATOR 1
The ejecting time can be set in the EXPULSION TIME (ms) parameter usually needed to
manage a rejected item.

NOTE:
If in the
PLU, the item "SELECTOR" is set at any value other than "NO EJECTOR",
then the DEVIATOR is never enabled;
2.18.2 Notes
In any case,
rejected products
are managed on the basis of the setting in
configuration. It means that if the rejection setting is DEVIATOR 1, the same
rejection output can be used for the rejection and for the selection of the first way
(operation 2.) and for the notification of accepted products (operation 3.).
Practically, in the presence of a selector, using the rejection with ejection makes
no sense (as generic rejected products must follow the idle way). Similarly, in case
3, if the ejection output is used to mark the accepted products it does not make
any sense using it for the rejected products as well (otherwise we fall back in 1.).
All combinations of SELECTOR parameters in CONFIGURATION and in PLU
which have not been described are ineffective or redundant.

Adjusting Dosage Via Feedback
“Feedback” means the possibility to adjust the upstream machine dosage via
digital outputs. This function aims at two different scopes:
In the operation where the lot acceptance is forced, it allows to start with high
dosage in order to get a positive average, avoiding rejected products at the
beginning of the process, then automatically decrease dosage without any
operator’s action.
Putting right that generally systematic disturbance making the product actually put
in the package different from the one programmed on the dosing scale. It is
