Batch processing is a non-continuous process that is started, conducted,
and terminated when a desired quantity has completed delivery. You can
stop batch delivery at any time prior to completion.
Setup
The following items must be programmed as follows:
SP Function Select Batch
SP Rate Set desired batch delivery rate
SP Batch Set desired delivery quantity
Start Batch
Return to the home screen. Note that the home screen indicates a ‘B’
control indicator for all channels selected to perform batching.
Home Screen
Press the START key three times. ‘B’ indicators will be blinking to indicate
channels with batch now in process.
The delivery process can be monitored as shown on the screen below by
observing that the PV Total increases toward the SP Batch amount, and
verifying that the PV Rate properly indicates the desired delivery rate. The
values in this screen are updated in real time. If the SP Function is set for
Batch, the SP Batch quantity appears on this screen.
