DFC Weighing Procedure (Unload Mode Only):
1. With the box ID and plot ID selected, press the LOAD/UNLOAD key.
The scale will store the Net weight as the tare weight, switch to Unload
mode, and display 0 units Net weight.
2. The scale is now ready to be Unloaded using the DFC. Position the
feeder over the container to be filled and start the fill by pressing the
F key followed by the ID/START key.
3. If at any time, you wish to pause the fill cycle, press the HOLD key.
The indicator will display PAUSED. To restart/continue the filling
operation, press the HOLD key again to “un-pause.” Or to abort the
fill, press the key.
4. Chattering will begin once the chatter weight is reached (fill weight –
trim weight). When chattering, the DFC output will pulse on and off.
The settings for these pulse durations are described in the
Recommended Settings section above.
5. The fill cycle will end once the preset fill weight is removed from the
scale. If DFCEND=YES was selected, the indicator will display DONE until a
key is pressed.
6. If there is enough material remaining on the scale, position the feeder
above your next container to fill and press the F key then the
ID/START key to start the next fill cycle (if the DONE message is still
displayed, simply press the ID/START key to start the next fill). If there
is not enough material on the scale when these keys are pressed, the
indicator will display ERROR. Repeat this step for subsequent fill cycles.
7. If you wish to check how much material is remaining on the scale,
switch to the Load mode by pressing the LOAD/UNLOAD key.
NOTE: The displayed Unload weight will be lost when you do this
and cannot be done in the middle of a fill cycle. Press the
LOAD/UNLOAD key again to switch back to Unload mode before
starting the next cycle.
8. If you have a value set for PURGE above, the indicator will be counting
the number of fill cycles completed and once the purge count (PURGE
value) is reached, the purge weight (P-WGT) will be added to the trim
weight and flash PURGE FEEDER on the display. At this time, you would
need to manually purge your feeder into the last container.
