11 DOSING BY FILLING FUNCTIONING MODE :
The filling functioning mode is a way to monitor a dosing cycle of a product by measuring the weight of a
receptacle placed on a load cell.
In this functioning mode, the dosing process is entirely managed by
e
Nod3-
D
and especially thanks to its
four digital outputs allowing to monitor the different phases of the cycle and to indicate errors.
Fig. 6 and 7 shown below represent graphically how a filling cycle is working and what is the influence of
the variables involved.
