6-8
6-5 CALF-14=“3” Weighing Mode (with no Supplementary Flow)
(Normal batching in built-in automatic program mode)
Output signal Output condition
Zero band Gross weight
≤
Zero band
Full-flow Final - Optional preliminary
≤
Net weight
Medium-flow Final - Preliminary
≤
Net weight
Dribble-flow Final - Free fall
≤
Net weight
Over limit Final + Over limit < Net weight
Under limit Net weight < Final - Under limit
• 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
• “Batch start” or “Discharge start”signal is ready to be input.
2
• The “Batch start” signal is input.
• The “Batch start wait timer” starts.
3
• 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.
4
• Net weight reaches the weight of “Final” –“Optional preliminary” or more.
• The “Full-flow” output is turned off.
• The “Medium-flow comparator inhibitor timer” start.
5
• Net weight reaches the weight of “Final” –“Preliminary” or more.
• The “Medium-flow” signal is turned off.
• The “Dribble-flow comparator inhibitor timer” starts.
6
• Net weight reaches the weight of “Final” –“Free fall” or more.
• The “Dribble-flow” signal is turned off.
• The “Judgment wait timer” starts.
7
• 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.
8
• The “Discharge start” signal is input.
• The “Discharge start wait timer” starts.
9
• The “Discharge start wait timer” completes the set time.
• The “Discharge output“ signal is turned on.
• The “Discharging time monitor timer” starts.
10
• Gross weight reaches 0 or less.
• The “Discharge valve close wait timer” starts.
• The “Discharging time monitor timer” is reset.
11
• The “Discharge valve close wait timer” completes the set time.
• The “Discharge output “ signal is turned off.
12
• The “Batch start” input signal for the next cycle is input.
• The “Batch finish” output signal is turned off.
• The judgment result output signal (Over limit or Under limit) is turned off.
* Now, the weighing sequence has cycled and restarts from sequence # 2 at this time.
