(7) After the judging time expires, Over/Under judgment is made. If the weighed value exceeds the
range of the Over/Under set value, the over signal or under signal is output. In weighing from
the second time onward, (3) to (6) are repeated in a like manner.
(8) When the weighing tank runs short of raw materials, the valves of the material tank are opened
by the output of the lower limit signal to feed raw materials into the weighing tank.
Example) In the case when comparing Upper/Lower limit comparison and Near Zero
comparison with Gross weight, Final and Over/Under with Net weight.
The feeding valves and discharge valves should be opened and closed through
the PLC or relay sequence according to the control signals from the F160.
