◎ Built-in Automatic Program Mode: Loss-in-Weight Batching (F101=4)
SP1 – Supplying Bin Gate
SP2 – Full Flow Gate
Free – Dribble Flow Gate
Start signal – Pin22
1. The Weighing Hopper/ Supply Bin is empty .The display shows "0", and all Gates are closed.
2. Open the Supplying Bin Gate.
3. When the GROSS Weight reaches "SP 1", the SP 1 Output (Pin 12) signal will come ON. Closed the
Supplying Bin Gate by using the SP 1 Output ON signal.
4. The displayed weight will exceed the SP 1 value by the Free Fall value. This weight is not necessarily
accurate - but accuracy is not needed at this moment since the purpose of this event is to fill up the
Weighing Hopper. The SP 1 value is always compared to GROSS weight.
5. Input a TARE signal (Pin 24) to ZERO display.
6. Input the Start signal via the Control I/O interface connector (Pin 22). When the Start signal is received, the
SP 2 and Free Outputs "come ON".
Note : When the Final Weight is 0, the Pin 11 and 10 are kept OFF .
7. Open the Full-Flow Gate and the Dribble-Flow Gate for Full-Flow filling into the Receiving Bin.
8. When the display reaches "Final - SP 2", the SP2 Output (Pin 11) signal will come OFF. Closed the
Full-Flow Gate by using the SP2 Output OFF signal.
9. When the display reaches "Final - FREE", the FREE Output (Pin 10) signal will come OFF. Closed the
Dribble-Flow Gate by using the FREE Output OFF signal.
10. Batch Finish signal is sent after the set time period (F103) or when the display is stable.
11. After Free Fall has stopped - check if the HI and LO (Pin 9, 8) signals are OFF. If both outputs are OFF
then the batch is completed correctly.
12. Automatic Free Fall is now recalculated for the next event.
13. The Weighing Hopper Discharge Gate will be opened using the Finish Output (Pin 7) ON signal.
14. Data Output is sent (Auto print Mode: BCD, RS-232C, RS-422/485, Printer or Current Loop). The NET
Weight data will be accumulated.
15. Signal (Pin 13) will refill using ZERO Band Output if needed. Ready for next batching event.
16.Ready for the next batching event.
17. If an Abort signal is sent (Pin 21) anytime after the Start signal is received, then:
(1) SP 1, SP 2 and Free signals will go OFF, and Gates will be closed.
(2) Batch Finish and Data Output signals will be sent.
(3) NET Weight data will be accumulated.
