PC Elements SCALE & SCALEDOS
A description of this resolution:
- PC Elements SCALE & SCALEDOS
As Gross weight is showing correct readings when the material is discharged, gross weight becomes zero. At this point of time tare the net weight by using TARENET pin in the SCALEDOS element.

We are looking for a solution for one of our problems concerning the usage of the SCALE and SCALEDOS Elements.
We are using scale boards (DSXW 110) with PC elements SCALE and SCALEDOS for a Batching application in a 'Feed Mill'. We are having a problem in the measurement readings from the scale element which is described below.
We have calibrated the loadcells using the known weights methods.
The Batch weighing process involves dosing of several ingredients on the scales. In the software we have built, after every ingredient is dosed on the scale, the 'Net wieght' is tared by setting the 'Tarenet' terminal on the SCALEDOS element. After all the ingredients are dosed the scale discharges/empties. During the load trials we have noticed that when the scales weight is discharged the Net weight is showing a big negative value (equal to the sum of all the net weights of all the ingredients) instead of zero value. The Gross weight reading shown is correct at all times. The customer is intersted in seeing a zerovalue after the scale is empty. How can we achieve a zero value reading of the net weight after the scale discharges ?
I have the program printouts of the SCALE and the SCALEDOS elements. Note, we have not used the 'Type circuits' that are supplied by Sweden.
