43
F22 = 9 (Check weighing 3:Loss in weight)
Output and Condition
* Relay OK output can be changed to OVER or UNDER by setting
f24
.
Triangle 2 is displayed when Gross
≧
Full, regardless of the
f24
setting.
OVER/UNDER is judged always and the result is output to the LED and the relay.
10.2.2. Simple
Batch
The weighing sequences of simple batch (
f22
=
10,
11
or
12
) are similar to those of
check weighing (
f22
=
7
,
8
or
9
) respectively. The differences are listed below.
1 Basically ON/OFF of the relay and the LED are reversed.
2 No judgment other than Zero band and Full before input of the Start signal.
3 The weighing completion condition is set by
f23
=
2
x and it is effective after Start.
4 The outputs of Preliminary and Free fall are off from weighing completion to the
next start.
5 Weighing completion can be output by setting
f24
and
f25
.
6 The start signal can be accepted after weighing completion even if the weight is
not within the zero band.
7 Over/Under output is set by
f23
=
3
x.
Start
Tare automatically when the Start is input if
f23
=
11
.
The READY mark turns off when the Start is input.
Weighing Completion
The weighing completion condition is set by
f23
=
2
x.
f23
=
20
: Either the STOP key is pressed or the Batch stop input is on.
f23
=
21
: Stable is detected after reaching Final.
Before reaching Final, the
STOP
key or Batch stop input forces weighing
completion even if
f23
=
21
.
