5.2 Overrun Menu
Explanation of SETUP-menu 2 – Overrun
Overrun can occur at the end of the batch process, as a result of a slow acting valve or
pump. Consequently, the accuracy is reduced. With this function, the Easybatch analyses
the actual overrun characteristic after every batch and corrects the overrun automatically.
2 OVERRUN
2.1 TIME Enter the expected time in the range of 0 – 99 seconds, needed by the
system to stop a batch.
With value 0, the overrun function is disabled.
It is advised to provide extra time in order to avoid an incorrect overrun
correction.
2.2 Preclose In case two-stage batch control is desired, output 2 can be used to be
switched-off before output 1. This switch moment is based on the remaining
quantity before the end of batch.
If pre-close is set to zero, output 2 will switch simultaneously with output 1.
