◎ Customer Programmed Control Mode: Loss-in-Weight ( F101 = 2)
SP1 – Supplying Bin Gate
SP2 – Full Flow Gate
Free – Dribble Flow Gat
1. The Weighing Hopper is empty as is the Receiving Bin. 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 the display.
6. Open the Full-Flow Gate and the Dribble-Flow Gate for Full-Flow filling into the Receiving Bin.
7. When the display reaches "Final - SP 2", the SP 2 Output (Pin 11) signal will come ON. Closed
the Full-Flow Gate by using the SP 2 Output ON signal.
8. When the display reaches "Final - FREE", the FREE Output (Pin 10) signal will come ON. Closed
the Dribble-Flow Gate by using the FREE Output ON signal.
9. After Free Fall has stopped - check to see if the HI and LO (Pin 9, Pin 8) signals are OFF. If both
outputs are OFF then the batch is completed correctly.
10. An Automatic Free Fall Compensation Command (Min. 200ms pulse to Pin 21) may be given at
this time.
11. If the GROSS weight of the Weighing Hopper is below the ZERO Band (Pin 13), the ZERO Band
Output will be ON. The ZERO Band Output will refill Weighing Hopper if needed.
12. Ready for next batching event.
