  6. Initial Power Up Display Line Master • Operate the apparatus engine and engage PTO to Hydraulic pump • Turn on electrical power to the FoamPro system • After a system check the Control Displays will read as shown above

  7. Make Foam Solution Line Master • Establish water flow to the foam capable discharge • The Line Control Display will indicate the water flow rate • Press the green I/O button on the Master Control Display • Press the green I/O button on the Line Control Display • The foam pump will start to deliver foam at the rate preset by the operator • The Master Control Display will indicate the foam injection pressure and the total water flow of all foam capable lines

  8. Total Water Flowed Line Master • To read the total water used on a line, press the SELECT button on the Line Control Display until the display reads as above. • To read the total water used on all foam capable lines, press the SELECT button on the Master Control Display until the display reads as above. • To reset the value on either display, press both the UP and DOWN buttons at the same time.

  9. Reading % Injection Rate • Press the SELECT button on the Line Control Display until the display reads the current rate. • To change the rate press the UP or DOWN button on the Line Control Display on the line you wish to change. • Pressing the UP or DOWN button will toggle between the preset values of Preset 1, Preset 2, Preset 3, and Custom rate.

  10. Changing Custom Injection Rate • Holding the UP or DOWN button will change the rate in 0.1% increments until the button is released. This new value will become the new custom rate until changed.

  11. Read Total Chemical Used Line Master • To read the total chemical used on whole the system, press the SELECT button on the Master Control Display until the display reads as shown. • To read the total chemical used on any specific line, press the SELECT button on the Line Control Display of the selected line until the display reads as shown. • To reset the value on either the Master Or Line Control Display, press both the UP and DOWN buttons at the same time.

  12. Read Water Flow Rate Line Master • To read the total water flow rate of the foam system, press the SELECT button on the Master Control Display until the display reads as shown. • To read the total water flow rate of a specific foam discharge, press the SELECT button on the appropriate Line Control Display until the display reads as shown.

  13. Read Foam Injection Pressure Master Line Or To read total water flow rate and injection pressure, press the SELECT button until the display reads as shown on the right. The top number will show the injection pressure and the larger bottom number will show the total flow rate. Or Press the Select button until the display reads as shown on the left for injection pressure only.

  14. Simulated Water Flow Operation The simulated flow function of the system allows the operator to control the line injection and foam pump manually. The water flow rate and the concentrate injection percentage rate can be set by using the display readout and the rate adjustment buttons on the Line Control Display Module. • This function provides the manual control requirement of NFPA. • This function will allow the operator to empty or fill the foam concentrate tank for cleaning, changing foam types, or refilling . • This function also provides a means of checking the operation of the foam pump at all normal rates of flow and injection without running the water pump. WARNING: When operating in the simulated mode, an outlet for the foam concentrate must be provided.

  15. Initiate Simulated Flow Operation Line Master • Press the SELECT button until the display reads as shown on the left. • Press the UP/DOWN buttons simultaneously. The display will read as shown on the right. • Start the system by pressing the I/O button on both the Master Control Display and the Line Control Display.

  16. Changing Simulated Flow Rate Press the UP button to increase the flow rate or the DOWN button to decrease the flow rate. The rate will change in increments of 100.

  17. Exit Simulated Flow Operation Line Master • Press the SELECT button until the display reads as shown on the left. • Press the UP/DOWN buttons simultaneously and the display will read as shown on the right. • The Line Control is now in the normal operating mode.

  18. Configuration Operation The FoamPro AccuMax system permits easy configuration setup of the system Display Controllers for proper operation. This process needs to be done at time of installation , or when a display is replaced. To enter the Configuration Mode, remove the left hand cover screw and o-ring with a 3/32” Allen wrench, located between the I/O and the UP button. Using the Allen wrench, depress the internal switch once. To exit the Configuration Mode, use the Allen wrench to depress the internal button once, and the Display will return to the normal operating mode. Be sure to replace both the o-ring and the screw after exiting the mode. The following slide will show the location of the Configuration switch.
