Description
The relationship of the output command to the flow rate obtained has changed significantly since the last calibration. There is now a smaller output required to get the same flow rate. This can be caused by: air leaks, a loose air cap, or a significant increase of air supply pressure. Note that the system continues to close the loop and generally maintain requested flow rates even after this alarm if there are no other alarms occurring. This alarm can provide an early warning of the possible failures. This alarm is controlled by the Adaptive tolerance parameter.
