Description

After the calibration table has been shifted or a new calibration table created, a nonincreasing table of flow command values is detected. Unstable flow rates encountered. Canister position change is not proportional to fluid regulator command. The canister position feedback is unstable. : Verify regulator is working properly . Verify fluid restrictor is suitable for the desired flowrates. Check proper feedback from the linear potentiometer. If this occurs as a result of a table shift, calibrate the colorvalve in which the cal table hasbecome non-increasing.
