Automatic Overrun Compensation
Based on previous batches. the 424 will automatically compensate for any overrun which may be caused by slow closing valves.
A maximum batch quantity can be programmed during set-up, so that the operator cannot enter a batch size that exceeds this limit.
If the flow signal cuts out midway through a batch, the output relays are de-energised, and an alarm signaled via an open collector output.
Remote push-button switches can be connected to the rear terminal strip, to start and stop batches.
The 424 Batch Controller can be programmed to automatically restart the batch after a preset time delay.
The instrument can be programmed to count up from zero, or to count down from the batch quantity.
End of Batch
An end of batch signal is provided via an open collector transistor output.
