Batch preset examples
The following examples describe the batch processing sequence for two different batch preset
configurations.
Note: For a detailed presentation of batch processing sequences, including how the
STOP and
RESUME functions affect processing, see the Series 3000 MVD transmitter manual.
Density curves None If an enhanced density variable is selected as the flow source, you must select
a density curve that will apply to this preset. The batch total will be based on
the density curve for that variable.
Overrun
(3)
0.0 kg • If Overrun is enabled as a control option, enter the amount over the target
value at which batch overrun will be indicated. For example, if the target is
250 kilograms and overrun should be indicated at 280 kilograms, enter 30.
• Overrun can be assigned to a discrete output, using the Discrete IO panel in
the ProLink II Configuration window.
Target
(4)
0.0 kg Enter the total at which the batch will be completed.
(1) This parameter is configurable only if Number of stages was set to 2.
(2) This parameter is configurable only if Enable end warning was set to Yes.
(3) This parameter is configurable only if Enable overrun was set to Yes.
(4) A non-zero value must be configured for Target before a batch can be started.
Example 1
Configure presets by quantity under the following conditions:
• The target is 200 kilograms
• The primary valve opens at the start of the batch and closes when
180 kilograms have been delivered
• The secondary valve opens when 100 kilograms have been
delivered
• The end warning occurs when 160 kilograms have been delivered
