Parameters
P566 Batch Pre-Warn
Enables or disables the pre-warn function associated with batch control, warning that
the batch is nearing completion.
Entry:
0 =OFF
f
1 = ON
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).
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 in order to improve the accuracy of the batch. The activity is internally
limited to ±10% of the batch setpoint
e.g. For Auto Batch Pre-Act
Entry:
0 = OFF
f
1 = Auto
2 = Manual
P569 Manual Batch Pre-Act Amount
Accessible only though Batch Pre-Act (P568), when Manual (2) is selected.
Manual
Enter a value to make the setpoint relay change status before reaching the setpoint. This
allows the feeding system to empty with each batch. The value of the manual pre-Act
entry is generally reflective of the material that is left in the feeding system.
