•
When an output condition is established, a relevant output terminal is turned on (power continuity with output COM).
•
An output terminal number can be selected with OUTF-01 through OUTF-08. See {Appendix C: Function List}
•
A set point signal output is turned off unconditionally when the operation mode is other than the normal mode.
Weighing process
* Programming with a PLC (Programmable Logic Controller) is required for this weighing mode.
Sequence # Process
1
•
The “Tare” signal is input.
•
The display shows “0”.
2
•
Gates G1 (full-flow), G2 (medium-flow), and G3 (dribble-flow) open.
•
The weight on the display is incremented, and reaches the weight of “Final –
Optional preliminary”.
•
The “Optional preliminary” output is turned ON.
•
Gate G1 closes.
3
•
The display shows the weight of “Final – Preliminary”.
•
The “Preliminary” output is turned ON.
•
Gate G2 closes.
4
•
The display shows the weight of “Final – Free fall”.
•
The “Final” output is turned ON.
•
Gate G3 closes.
•
Weighing completes at a stable display.
* The display shows the final weight, indicating that hopper 2 has been filled to
that weight. Use the over limit/under limit setting to check whether the
weighing value is within limits.
5
•
Gate G4 (Discharging gate) opens to discharge and fill the container.
* The use of the zero range setting can check if the ingredient has been
completely discharged.
