DFC Weighing Procedure (Unload Mode):
1. Verify the scale is in Load mode (the Unload annunciator will be turned
off). You can toggle back and forth between Load and Unload mode
by pressing the LOAD/UNLOAD key.
2. With the scale empty, verify the scale is showing 0 units Gross. If not
in Gross mode, press the 0 key then the TARE key to clear the stored
tare weight and the indicator will display Gross weight.
3. Now Load the scale with the amount of material you wish to distribute
(this should be greater than or equal to your preset fill weight). If you
wish to key in a known Net weight of the material you just loaded, go to
the next step. Otherwise, go to step 5.
4. To set the indicator’s Net weight, press the F key followed by the
NET/GROSS key. The indicator will display NETWT=. Press ENTER to
display the current Net weight value. Key in your known Net weight,
then press ENTER. The indicator will now display the live Net weight
with your keyed in weight value.
5. 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.
6. 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 press the F key
followed by the ID/START key.
7. 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 “unpause.” Or to abort the fill,
press the key.
8. 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.
9. 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.
10. 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.
