3.2.3 End-of-Batch
The End-of-Batch is defined as being when the Batch Quantity is
reached, the flow has stopped, and the Signal Timeout period has
expired.
If the Signal Timeout is set to zero, the End-of-Batch is defined as
being when the Batch Quantity is reached, regardless of whether the
flow has stopped.
The Batch Controller cannot be reset or restarted until the End-of-Batch
and similarly, for an RS232/422/485 interface, data will not be output
until the End-of-Batch has been determined. Consequently, it is
strongly recommended that the Signal Timeout period be kept fairly
short.
End-of-Batch Signal
An End-of-Batch signal from an open collector transistor is output on
terminal 30 and the output is identical to the Output Pulse circuit as
shown in Section 3.7.
When reaching the End-of-Batch, the output transistor is switched on
and will remain in the "on" state until the instrument is reset.
