The system was built in 2007
Many people have had hands on it over the years it seems.
I am not a programmer but a humble electrician.
The air flow sensor needs min air flow and max air flow parameters set in the HMI because we cannot access the PLC program. Any changes to get the system working need to be made on the HMI.
The problem is: when I enter 0 m3/hr for min, and 500 m3/hr for max, Im getting a readout of 2500 m3/hr, which doesnt change. I know its something basic but trial and error isnt getting me anywhere.
Its a Unity Premium PLC and Schneider Magelis HMI.
Thank you
