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

NOTE: If necessary, verify flow meter calibration.
See Verify Flow Meter Calibration, page 39, for
instructions.
Configure Pressure Loop
Settings
The PCF system uses variables (Kp and Ki) in the soft-
ware calculations to accurately and precisely control the
fluid pressure.
NOTE: It is recommended that these values not be
changed from the factory defaults of 32.00 for Kp
and 128.00 for Ki. However, if the values need to be
adjusted, see Verify Flow Meter Calibration on page
39.

Adjust Pressure Sensors

Set pressure offsets and pressure limits.
NOTE: Inlet sensor settings will be grayed out on
this screen for systems with heated fluid plates.
1. With the system in setup mode, navigate to the Fluid
Plate x, screen 5 (Pressure Sensors).
2. Press to access the fields to make changes.

NOTE: For the following steps, press
to navigate through each field, and
to open drop-down menus and enter changes or
selections.
3. Set the desired offset for the inlet and outlet pres-
sures between 0 and 100 psi (0.7 MPa, 7.0 bar).
Remove all pressure on the sensors, and then
adjust the offset so the measured value reads 0.
NOTE: It is recommended that offsets should not be
changed from the factory defaults of 0.
4. Set the desired minimum and maximum pressure
limits for the inlet, and the desired maximum pres-
sure limit for the outlet.
5. Set the error type (alarm or deviation) that will be
issued:
• If the minimum inlet pressure decreases below
the setting.
• If the maximum inlet pressure increases above
the setting.
• If the maximum outlet pressure increases above
the setting.
