12.8.2
P564 Batch Setpoint
Sets the batch total. When the amount of material delivered reaches this point, the batch relay
contact opens (P100) to signal the end of the batch. (
f = 0.000).
Enter the setpoint of the units of weight selected (P005).
Note
The batch setpoint can be modified while in RUN mode using the up/down arrow keys.
12.8.3
P566 Batch Pre-Warn
Enables or disables the pre-warn function associated with batch control, warning that the batch
is nearing completion.
Entry:

P567 Batch Pre-Warn Setpoint
Sets the setpoint for the pre-warn function (P566). When the batch reaches the setpoint, the
relay contact associated with the pre-warn function (P100) closes (
f = 0.000).
Enter setpoint in units of weight selected (P005).
12.8.5
P568 Batch Pre-Act
Acts on the batch operation such that when the batch totalizer is reset, the batch total is
compared to the setpoint (P564). The difference is then applied to pre-act on the setpoint for the
next batch to improve the accuracy of the batch. The activity is internally limited to ±10% of the
batch setpoint.
Entry:
0 = OFF
