for values. Press
6. Press to exit edit mode.
NOTE: If necessary, verify flow meter calibration.
See Verify Flow Meter Calibration, page 35, for
instructions.

Configure Control 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 not be
changed from the factory defaults of 32.00 for Kp,
128.00 for Ki, and 0.00 for Kd. However, if the values
need to be adjusted, see Verify Flow Meter Calibra-
tion on page 35.

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 set of screens.
2. Press to scroll to the Pressure Sensors
screen (screen 5).
3. Press to access the fields to make changes.

NOTE: For the following steps, press
and to navigate through each field, and
to open drop-down menus and enter changes
or selections.
4. 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.
