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, a relevant output terminal is turned on or off. “Full flow”, “Medium flow”,
and ”Dribble flow”: OFF, the other outputs: 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
# Process # Process
1
•
[ZERO] is pressed.
•
Gross weight becomes ”0”.
2
•
A container is placed on the weighing platform.
3
•
[TARE] is pressed
If SqF-26=”1”:Tared at batch start automatically
•
Weight is tared at sequence # 4. Automatically.
•
Weight is tared.
•
Net weight becomes “0”.
4
•
The “Batch start” signal is input.
If SqF-26=”1”:Tared at batch start automatically
•
Weight is tared at the “Batch start” input.
•
(Tare action is the same as [TARE].)
•
The “Batch start wait timer” will start 1 second (time
for visual inspection for the tare action) later.
•
The “Nozzle down” signal is turned on.
•
The “Batch start wait timer” starts.

(Continued)
In case of No supplementary flow
•
Supplementary flow is not made when;
•
If SqF-09
≠
”0” and judgement result is either
“Acceptable weight” or “Over limit”.
•
If SqF-09=”0”: No supplementary flow setting.
•
Net weight is judged and either “Over limit”,
“Acceptable weight”, or “Under limit” signal is
turned on based on judgement result.
•
The “Batch monitoring timer” is reset.
•
The net weight is accumulated automatically.
•
The data is output from the interface set for auto
print.
•
Weighing process leads to sequence #13.
In case that supplementary flow is made
•
Supplementary flow is made when;
•
If SqF-09
≠
”0” and judgement result is
“Under limit”.
•
The “Nozzle down “ signal is turned on.
•
The “Batch monitoring timer” starts.
5
•
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.
10
•
The “Batch monitoring timer” completes the set
time.
•
The “Dribble-flow“ signal is turned off.
•
The “Supplementary flow open timer” starts.
6
•
Net weight reaches the weight of “Final” –“Optional
preliminary” or more.
•
The “Full-flow” output is turned off.
•
The “Medium-flow comparator inhibitor timer”
starts.
11
•
The “Supplementary flow open timer” completes
the set time.
•
The “Dribble-flow“ signal is turned off.
•
The “Nozzle down“ signal is turned off.
•
The “Supplementary flow close timer” starts.
7
•
Net weight reaches the weight of “Final”
–“Preliminary” or more.
•
The “Medium-flow” signal is turned off.
•
The “Dribble-flow comparator inhibitor timer”
starts.
8
•
Net weight reaches the weight of “Final” –“Free
fall” or more.
•
The “Dribble-flow” signal is turned off.
•
The “Judgment wait timer” starts.
12
•
The “Supplementary flow close timer” completes
the set time.
•
Judgement is made.
If “Under limit”;
•
Repeat the weighing process from sequence # 9.
If “Acceptable weight” or “Over limit”;
•
The “An acceptable weight” or “Over limit” is
turned on.
•
The batch monitoring timer is reset.
•
The net weight is accumulated automatically.
•
The data is output from the interface set for auto
print.
13
•
The container has been filled with ingredient.
•
The container is removed from the platform
9
•
The “Judgment wait timer” completes the set time.
•
Display becomes stable. (Already "Stable" in the
chart on next page.)
•
If automatic free fall compensation is being used,
its calculation will be made.
•
Judgement is made.
14
•
To tare, input Tare signal or press [TARE].
•
If Sq F-26=”1”(Tared automatically at batch start), tare
is cleared automatically within zero band.
