1 Waiting for start signal input
SP1/SP2/SP3 blinks
SP1/SP2/SP3 blinks at medium speed
2 Execution of tare subtraction Tare lights up
Setting mode 2-1:
final and over/under comparison
Tare subtraction
(5 pin)
Sets the compared weight value to z
ero (In the chart, tare subtraction is executed by external input and the NET weight is set to zero.)
3 Start signal ON is input
SP1/SP2/SP3
lights up
Setting mode 5-1: input selection Start (input selection)
Set point 1 (7 pin) ON
Set point 2 (8 pin) ON
Set point 3 (9 pin) ON

Output of adjust feeding in prog-
ress signal
HI or LO blinks
Setting mode 0-7: over
Setting mode 0-8: under
Setting mode 0-9: final
Setting mode 2-1:
final and over/under comparison
Setting mode 2-2:
over/under
comparison mode
Setting mode 5-2: output selection
Output selection:
waiting for external
judging (23 pin) ON
* 4
External judging input is enabled when setting mode 2-2: over/under comparison mode is set to 1: compare when external judging input is ON.
If the over-under comparison result is anything other than GO, the displayed result will blink and a waiting for external judging signal will turn
ON (
signal for over/under comparison result will also turn ON)
Switches to [No.12] sequence if over/under comparison result is GO.
* 6
Judged to be under when compared weight value < final setting value - under setting value
Judged to be over when compared weight value > final setting value + over setting value
Judged to be GO when final setting value + over setting value ≧ compared weight value ≧ final se
tting value - under setting value
11
Waiting for input of judging signal
Output of adjust feeding in prog-
ress signal
HI or LO light goes
out
Setting mode 0-7: over
Setting mode 0-8: under
Setting mode 0-9: final
Setting mode 2-1:
final and over/under comparison
Setting mode 1-2: judging time (t2)
Setting mode 5-1: input selection
Setting mode 5-2: output selection
Judging (input selec-
tion)
Output selection:
waiting for external
judging (23 pin) OFF
* 5
When judging signal ON is input, the blinking judging result will go out, output of waiting for external judging will turn OFF, and judging timer
will begin operating.
Switches to [No.10] sequence if the over/under comparison result is anything other than GO when judging is re-executed after the judging
timer has elapsed.
Switches to [No.12] sequence if ov
er/under comparison result is GO.
* 6
Judged to be under when compared weight value < final setting value - under setting value
Judged to be over when compared weight value > final setting value + over setting value
Judged to be GO when final setting value + over setting value ≧ compared weight value ≧ final setting value - under setting value

D lights up
GO lights up
Setting mode 1-3: complete output time (t3)
Setting mode 2-2: output selection (22 pin)
Setting mode 2-2:
complete signal output mode
Output selection: GO
(22 pin) ON
Output selection:
complete (22 pin) ON
* 7
The timing of complete signal output depends on setting mode 2-2: complete signal output mode (shown in the chart as 1: after judging
timer has elapsed.)
The timing of over/u
nder comparison holds the weight value compared at complete ON regardless of setting mode 2-2:over/under compar-
ison mode

After complete output timer has
elapsed

Setting mode 2-2: output selection (22 pin)
Output selection: GO
(22 pin) OFF
Output selection:
