• 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.
