6-8 CALF-14="5" Weighing Mode

(Nozzle controlled weighing mode)
Output signal
Zero band
Full-flow
Medium-flow
Dribble-flow
Over limit
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
#
• [ZERO] is pressed.
1
• Gross weight becomes "0".
• A container is placed on the weighing platform.
2
• [TARE] is pressed
If SqF-26="1":Tared at batch start automatically
• Weight is tared at sequence # 4. Automatically.
3
• Weight is tared.
• Net weight becomes "0".
• 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].)
4
• 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.
• The "Batch start wait timer" completes the set time.
• "Full-flow", "Medium-flow" and "Dribble-flow"
5
output signals are turned on.
• The "Full-flow comparator inhibitor timer" and
"Batch monitoring timer" start.
• Net weight reaches the weight of "Final" –"Optional
preliminary" or more.
• The "Full-flow" output is turned off.
6
• The "Medium-flow comparator inhibitor timer"
starts.
• Net weight reaches the weight of "Final"
–"Preliminary" or more.
• The "Medium-flow" signal is turned off.
7
• The "Dribble-flow comparator inhibitor timer"
starts.
• Net weight reaches the weight of "Final" –"Free
fall" or more.
8
• The "Dribble-flow" signal is turned off.
• The "Judgment wait timer" starts.
• The "Judgment wait timer" completes the set time.
• Display becomes stable. (Already "Stable" in the
chart on next page.)
9
• If automatic free fall compensation is being used,
its calculation will be made.
• Judgement is made.

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.
9
• 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.
• The "Batch monitoring timer" completes the set
time.
10
• The "Dribble-flow" signal is turned off.
• The "Supplementary flow open timer" starts.
• The "Supplementary flow open timer" completes
the set time.
• The "Dribble-flow" signal is turned off.
11
• The "Nozzle down" signal is turned off.
• The "Supplementary flow close timer" starts.
• 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";
12
• 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.
• The container has been filled with ingredient.
13
• The container is removed from the platform
• To tare, input Tare signal or press [TARE].
• If Sq F-26="1"(Tared automatically at batch start), tare
14
is cleared automatically within zero band.
