A batch can be canceled (aborted) as follows:
!
Interrupt the batch as described above.

While the batch is stopped (the relay is de-energized), use the or

soft button replaces the RESUM soft button.

All lines are de-selected and the

value increases by one.
The cancelled batch is not re-dispensed.
The flow measured before it was cancelled is not backed out of
Total all Batches:
.
Because flow information is only computed by the flowmeter at the configured display
update interval, the volume dispensed in a batch will typically overshoot the configured
Batch Amount. The relay is de-energized when the measured total equals or exceeds the
batch volume. The degree of overshoot depends on the batch size, the flow rate and the
update interval. You should not configure long update intervals when dispensing small
batches from a high flow rate, as in this situation the overshoot could be a significant
fraction of the batch size.
If the
Batch Start
type is configured as
AUTO,
then operation is as follows:
Immediately upon entering
Run Mode,
the flowmeter accumulates the volume of fluid
flowing in two totalizers associated with the specific
Relay Channel
. If the relay
channel is brought onto the display (using the
RELAY
soft button), the totals are
displayed to the right of the labels

and

and the
values will be seen to advance.
However, the channel will operate in the manner described
here whether it is on the display or not.

In this mode of
Process Control
, the flowmeter is partitioning the flow in the pipe into
batches of a defined amount. Within each batch, it displays the total flow so far for that
batch. It counts the batches. At the end of each batch, the relay energizes for a defined
time period and then de-energizes. An example of what the energized relay might do is to
switch power to a pump or open a valve that results in some other fluid being injected
into the measured fluid stream.
