6-4.
Over/under comparison mode
Over and Under based on the target value are set, with
respect to each of which weight values are compared in
this mode.
This is convenient to simple checkers.
■
Over/under comparison mode
Set Target, Over, and Under as desired, and set the weight to be compared by comparison weight value.
Also, set the comparison timing accordingly.
- Target value (setting mode 0-9)
Input range/0 - 99999
- Over (setting mode 0-7), under (setting mode 0-8)
Input range/0 - 9999
- Comparison weight value (setting mode 1-4 weighing function 1)
Determine the weight to be compared with (target value + over) and (target value - under).
- Comparison condition
In over/under comparison mode, control outputs (HI, GO, LO) are made under the following
conditions:
- HI output (
HI lights):
Turns ON when the weight value > (target value + over)
- GO output ( GO lights):
Turns ON when (target value - under)
≦
weight value
≦
(target value + over)
- LO output ( LO lights):
Turns ON when the weight value < (target value - under)
- Comparison timing (setting mode 1-4 weighing function 1)
Determine the timing of comparison with (target value - under) and (target value + over).
* If "Compare in a stable condition" is selected, comparison is made only while " " is lit (in a
stable condition).
* Determine whether near zero is ON or OFF by near zero comparison mode.
Also, “ except near zero ” indicates a state in which " " is unlit.
Comparison weight value
0: GROSS
1: NET
2: Comparison OFF
Weighing function 1
* If "Comparison OFF" is selected, control outputs (HI, GO, LO) are not made.
Comparison timing
0: Compare regularly
1: Compare in a stable condition.
2: Compare regularly except near zero.
3: Compare in a stable condition except near zero.
4: Comparison is made when the external judgment input is ON.
