Description
As Accuflow steps down through the 10 points in the calibration table, it expects a lower flow for each decrease in the commanded flow value. In this case, the flow did not decrease. This can be caused by low or pulsing fluid pressure, insufficent exhaust or no quick exhaust on the fluid pilot air.
Remedy
Retry the calibration. Check that an adequate and stable flow rate is provided by the system for this color. Decreasing the leveling trys might help. Check that the fluid pilot regulator air line has adequate exhaust capability. Re-evaluate the size of the restrictor in the gun.
