11.6.1 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 Section 18.4.
End warning
(2)
80.00% of target or
0.0 kg quantity
• If End Warning is enabled as a control option, enter the quantity subtracted
from the target, or the percent of the target, at which the end warning will
occur. See the examples later in this section.
• End Warning can be assigned to a discrete output. See Section 8.3.2.
• To enable the end warning, see Section 11.5.
Targe t
(3)
0.0 kg Enter the total at which the batch will be completed.
Overrun
(4)
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. See Section 8.3.2.
• To enable overrun indication, see Section 11.5
(1) This parameter is displayed only if No. of Stages was set to 2.
(2) This parameter is displayed only if Enable End Warning was set to Yes.
(3) A non-zero value must be configured for Target before a batch can be started.
(4) This parameter is displayed only if Enable Overrun was set to Yes.
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
