Configure Flow Meter Settings

The accuracy of the PCF volume reporting depends on precise adjustment of the K-factor(s). The fluid plate uses the K-factor(s) to calculate the volume dispensed. If the set value is not correct, the system still delivers repeatable flow rates; however, the reported value may not be correct. See Verify Flow Meter Calibration, page 42, for additional K-factor information.

Table 5: Flow Meter K-Factors

Part	Description	K-Factor
246652	High Resolution Helical	7000
	Gear Meter
246340	Heated Helical Gear	3500
	Meter
16E993	Ultra High Flow Meter	33000

Set Flow Meter K-Factor

NOTE: In systems without a flow meter, the flow meter settings will be grayed out.

1.With the system in setup mode, navigate to the Fluid Plate x, screen 4 (Pressure Loop and Flowmeter Set- tings).

2.Press to access the fields to make changes.

System Setup

3.Press to open the Meter Type drop-down list, and select the meter type used by the system. Select Volume for volumetric flow meters or Mass

for mass flow meters. Press to enter the selec- tion.

4.Press to move to the K-Factor field. Key in the K-factor value. See Table 5: Flow Meter K-Factors

for values. Press to enter the value.

5.Press to exit edit mode.

NOTE: If necessary, verify flow meter calibration. See Verify Flow Meter Calibration, page 42, for instruc- tions.

Configure Pressure Loop Settings

The PCF system uses variables (Kp, Ki, and Kd) in the software calculations to accurately and precisely control the fluid pressure.

NOTE: It is recommended that these values are not changed from the factory defaults of 32.00 for Kp,

128.00for Ki, and 0.00 for Kd. However, if the values need to be adjusted, see Manually Adjust Control Loop Parameters on page 43.
