•
When an output condition is established, full flow, medium flow, and dribble flow outputs are turned off, but the other
outputs are turned on.
•
Once the full flow, medium flow, and dribble flow are turned off, they are not turned on until the next start of batching.
•
Over limit / Under limit is activated based on the net weight upon batch finish. (May be changed to customer
programmed control mode operation)
•
The zero band is a customer programmed control mode operation.
Weighing process
Sequence # Process
1
•
The “Zero band” is output.
•
Ingredient continues to be supplied until the “Full” signal is output.
2
•
The “Tare” signal is input at stable display.
3
•
The “Batch start” signal is input.
•
The “Batch start wait timer” starts.
4
•
The “Batch start wait timer” completes the set time
.
•
“Full-flow”, “Medium-flow” and “Dribble-flow” output signals are turned on.
•
The “Full-flow comparator inhibitor timer” and “Batch monitoring timer” start.
5
•
Net weight reaches the weight of “Final” –“Optional preliminary”.
•
The “Full-flow” output is turned off.
•
The “Medium-flow comparator inhibitor timer” starts.
6
•
Net weight reaches the weight of “Final” –“Preliminary” or more.
•
The “Medium-flow” signal is turned off.
•
The “Dribble-flow comparator inhibitor timer” starts.
7
•
Net weight reaches the weight of “Final” –“Free fall” or more.
•
The “Dribble-flow” signal is turned off.
•
The “Judgment wait timer” starts.
8
•
The “Judgment wait timer” completes the set time.
•
Display becomes stable.
•
If automatic free fall compensation is being used, its calculation will be made.
•
The “Batch Finish” output signal is turned on
•
If there is excess or shortage, a judgment result output signal (Over limit or
Under limit) will be turned on. (“Within limit” is on in the chart on next page.)
•
The “Batch monitoring timer” is reset.
•
The net weight is accumulated automatically.
•
The data is output from the interface set for auto print.
