This section describes two common situations in batch processing that may require special attention 
from the operator.

In normal processing, the batch totalizer increments whenever flow is detected. To run fluid through 
the tubes without incrementing the batch totalizer:

1. Ensure that the Inhibit Totalizer batch control function has been assigned to a discrete input, as 

described in Section 11.7. 

2. Activate the discrete input or discrete event.

3. Run fluid through the tubes as desired.

4. When you are ready to resume totalizing, deactivate the discrete input. 

In general, to end a batch:

•

Automatically, the target must be reached and flow must be stopped.

•

Manually, the batch must be stopped (paused) and flow must be stopped.

To end a batch while flow is present:

1. Ensure that the Inhibit Flow batch control function has been assigned to a discrete input, as 

described in Section 11.7. 

2. When the batch total reaches the target, activate the discrete input so that the batch can end 

normally.

Batch AOC (Automatic Overshoot Compensation) keeps the actual quantity delivered as close as 
possible to the batch target, by minimizing the amount of overshoot.

If batch AOC is enabled (see Section 11.5), batch AOC calibration is required to provide data for the 
compensation process. Thereafter, batch AOC calibration is recommended:

•

Whenever consistent overshooting or undershooting of the target occurs

•

If equipment (valve or pump) is changed

To perform batch AOC calibration:

1. From the Maintenance menu, select 

 (see Figure 4-2).

2. Select 

.

3. Select 

.

4. Press 

 repeatedly to return to the operation screen.

5. Run 2 to 10 batches.
