*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 2x and it is effective after Start.

4The 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.

6The 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 3x.

Start

Tare, when the Start is input automatically if f23 11.

The READY mark turns off when the Start is input.

Weighing Completion

The weighing completion condition is set by f23 2x.

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.
