Manufacturer wording — %sCal. table adapted out, down
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PNT2-666 (“Cal. table adapted out, down”): The relationship of the output command to the flow rate obtained has changed significantly since the last calibration. First check: Check that the air cap is tight on the gun. Likely part: Air cap (Air cap (paint atomizer)).

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 early warning of the possible failures. This alarm is controlled by the Adaptive tolerance parameter.
Remedy
Check that the air cap is tight on the gun. Check, clean and possibly replace the air cap. Check for leaks in air lines or at fittings. Check for cracks or breaks in the gun. Check for a large increase of air supply pressure. Recalibrate to immediately clear the alarm. Increase the Adaptive tolerance parameter to allow larger changes without alarming
