A bit of a valve/ control question. Anyone out there running the newer Experion system on your DCS and also have a fair amount of DVC 6200 that operations like to keep clamped at -5%?
If so we had an issue where one of out DVC’s was failing causing the DCS to go into an initialization error which in turn prevented the board guy from making SP changes from the DCS. So when we troubleshot it we noticed that the mA value was 3.2 which struck me as weird. Also when the power was cycled the positioner would work.
So has anyone had or seen a similar issue?
