Stop Batch
[0x0F]
Stops a batch which is in progress and has not yet stopped. This simulates
pressing
Stop
.
The manner in which the batch stops is determined by the Stop key action
[63,0,61]:
If no active alarm with more than info severity is present and the batch
remaining quantity [63,0,3] is less than minimum preset quantity [63,0,27]
then the batch ends.
If
Stop
key action is Low Flow (0], then the system waits for the flow rate
to become zero before starting pump stop delay timer for closing the
pump.
If
Stop
key action is Immediate (1), then the batch stops immediately
without using a pump stop delay.
The DL8000 sets a flag to indicate that the batch has stopped (and is
restartable).
Flags Immediately Set
Batch Stopped (if batch gets stopped)
or
Batch Ended (if batch is ended)

and “Start to Load” messages. If batch is
complete, the DL8000 displays “Batch Completed”
and “Please Wait” messages. In both conditions,
the DL8000 waits for the next command from the
TAS.
