Automatic Batch Control
Operation
1. Both valves are closed with an empty barrel
in place. The batched total is displayed in the
upper display, the preset is selected for the
lower display.
2. The START button is pressed. Both valves
open. The barrel begins to fill.
3. When the batch total reaches a value of
50.00 (Preset [55.00]
– Pre-close [5.00]) the
full-flow valve closes. The fill rate of the tank
slows as a result.
4. When the batch is complete, the restricted-
flow valve closes. If overrun occurs, then the
next batch will adjust for this offset amount to
maintain accuracy.
5. After the batch is completed, the operator
removes the full barrel and places an empty
barrel; the new batch starts automatically
after 60 seconds (Time Delay).
6. The new batch begins automatically after 60
seconds, both relays activate and both
valves open.
7. At the end of the shift, press STOP twice to
stop the batch process.
