For some columns the max delta-column pressure (media) is significantly lower than the max pre-column pressure (hardware).
To protect the media if a delta-column pressure measurement is not available (that is, when column valve V9-C or V9H-C is not used), the pre-column pressure alarm must be manually set to the value in the column list that is the lowest of the max pre-column pressure and the max delta-column pressure.
Delta-column pressure alarms
If column valve V9-C or V9H-C is installed the delta-column pressure will be measured, but the alarm must be set manually if needed.
