Enter maximum volume of tank in input box labeled tank capacity.
Select control valve type: standard or fast.
Enter Control Valve Calibration number provided in manual into control valve calibration input box.
The Control Valve Calibration number is a 4 digit number used to fine tune control characteristics. The number is in the form XXYZ, and is defined as follows:
-
XX - Valve Speed.
-
The higher this value, the quicker the valve responds. If it is set too high, the actual flow rate will oscillate continuously around the target rate. If it is set too low, the target rate will never be reached.
|
-
Y - Output Deadband.
-
Sets the minimum speed that the valve will ramp down toward before stopping. The higher this value, the sooner the valve will become stationary.
-
Z - Control Deadband:
-
Sets how close the actual flow rate must be to the target rate to be considered acceptable. When the actual and target rates are within this range, the valve will remain stationary. A higher value allows for a larger disparity between actual and target rate.
-
Use the recommended values in the following table to initially set the Control Valve Calibration number. Evaluate machine behavior during operation, and if necessary, adjust the value to attain optimum system performance.
