Adjust Ratio and System

Verify Desired Ratio Mode
The machine can be run in either Ratio by Weight Mode
or Ratio by Volume Mode. Since PFP materials are
blended by weight, normally have air mixed in the fluids,
and are checked by weight, it is recommended that
these materials be run in Ratio by Weight Mode. This
calibrates the machine to the exact materials that you
are pumping, and gives the most accurate ratio checks
by weight.
Ratio by Weight Mode is indicated by a balance scale in
the upper right corner of the screen. Ratio by Volume
Mode is indicated by a beaker in the upper right corner.
The mode can be selected in the Enable Setup Screen
3. See Enable Setup Screens, page 73.
In Weight Mode, the scale in the upper right corner of
the screen will have an X through it until the machine is
calibrated, and a ratio check is complete. Spray Mode
can not be used until the X is cleared from the scale by
doing a Pump Test Calibration, and performing a Ratio
Check. See Batch Dispense or Ratio Test, page 50.
If you are running Ratio by Volume Mode, the mix ratio
by weight still needs to be set on the Ratio Test Setup
Screen. This allows ratio checks to be done by weight.
See Appendix A, Ratio Test, page 72.
Adjust Ratio Set Point
1. Turn key to right (setup position). Yellow LED will
flash and the Setup mode Home screen will display.
2. Press
and
to change the volume or weight
ratio setting. Current setting of volume or weight is
shown in the upper right corner.
3. When desired ratio is displayed, turn key to left. Yel-
low LED will turn off.
4. Change all settings in the user-interface to the
desired values. See Appendix A - User Interface
Display on page 68 for detailed screens informa-
tion, including navigation and instructions.
NOTE: High mix or viscosity ratio (greater than 3:1)
materials may require adding restriction to the B side
outlet.

Temperature Settings
Set all temperatures per your materials data sheet spec-
ifications.
Feed Tanks
Temperature is controlled by an adjustable thermostat
on the heater mounted on the "A" side feed module.
Power to the tank heater is supplied from the power
switch (BB) above the dosing valves. Tank material tem-
perature is displayed on the Supply screen under the
tank icon. The circulating heated fluid temperature is
displayed on the temperature gauge next to the heater.
1. Set heater control knob to 4. This is approximately
120°F (49°C).
2. After the red light goes out, check the temperature
on the gauge and adjust as needed to get desired
temperature.
NOTE: Tank will not heat up faster by increasing the
temperature setting.
