Yokogawa 414 Batch Controller - Manual (Page 11)

The Batch quantity can only be set while the instrument is in non-operational
state such as when the batch is complete, or if the batch process has been
interrupted. However, the Batch key can be pressed while in the run state and
the Batch quantity checked. All digits will flash to signal the quantity cannot be
changed.
STARTING A BATCH
To start the process the RUN key is pressed. The Run LED will light and the
instrument will begin to totalise from zero or, if programmed for the count down
mode, the display will decrement from the batch quantity.
The batcher has two output relays and these are energised and de-energised as
described in section 3.2.
STOPPING
The process can be stopped at any time by pressing the STOP switch. Once the
process has been interrupted in this way it can be continued by pressing the RUN
switch or the process can be aborted and the instrument reset by pressing the
STOP switch a second time.
When the process is interrupted, the STOP LED will flash to prompt the
operator to either restart or abort the batch.
RESETTING
The instrument can be programmed to reset in one of two ways.
At the end of a batch, the STOP key must be pressed to reset the Batch
Total. If the instrument is programmed to count down, the Batch
Total will then revert to the preset quantity. If it is programmed to
count up, the Batch Total will clear to zero.
If Auto Reset is programmed, the Batch Total will automatically reset
when the RUN key is pressed and then commence the next batch.
