Automatic Batch Control
The automatic batch control feature is used for batches that start automatically once the previous batch is completed.
There is no opportunity for the operator to change the batch size between batches. The batch can be controlled using
a
connected to the remote contacts.
System Setup
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.
Batch Start
The START button or (F1) is
pressed. Both valves open. The
barrel begins to fill.
Preclose Valve
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.
Completed Batch
When the batch is complete, the
restricted-flow valve closes. If
overrun occurs, then the preset
must be adjusted to compensate for
the overrun.
Start Delay
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).
Automatic Start of Next Batch
The next batch begins automatically
after 60 seconds, both relays
activate and both valves open.
Pause
At any time, press the STOP button
or Stop key (F3) once to pause the
process.
Resume Batch
If the batch has been paused, then
press START button or (F1) to
resume the batch process.
Stop Process

button or Stop key (F3) twice to stop
the batch process.
