  1. CAFS On-Line Orientation Montgomery County Fire & Rescue Service Operating the CAFS Controllers

  2. Controllers Module Objectives • Understand FoamLogix Controller Layout • Understand FoamLogix Injection Use • Understand CAFSPro Controller Layout • Understand CAFSPro Injection Use  MCFRTA 2008

  3. FoamLogix and CAFSPro Controllers • FoamLogix Concentrate Injection Control CAFSPro Air Injection Control  MCFRTA 2008

  4. Controllers • Both are laid out in similar fashion. On/off button in upper left. Informational display change button in upper right. Arrows control amount of foam or air added. Bar scale across bottom gives visual representation of percent capacity used.  MCFRTA 2008

  5. FoamLogix Controller • On/Off Button • Switch Displays Button • Up and Down Arrows • LED Bar Graph  MCFRTA 2008

  6. On/Off Button • On/Off Control for Foam Pump • Foam Pump Automatically Powers On with road-to-pump engagement • Lit LED on bar graph shows you that foam pump is on  MCFRTA 2008

  7. Switch Displays Button • Switches between the 4 informational displays  MCFRTA 2008

  8. Informational Display Choices • Flow • % (Foam Injection) • Total Flow • Total Foam  MCFRTA 2008

  9. Info Displays - Flow • Real-time Flow through the Foam Manifold (gpm, 30-800) • This is the combined flow through the manifold. So if you have more than one handline off you will have to estimate percentages to figure out what each handline is flowing. • Read from Paddlewheel Flow Sensor This number indicates that there is 116 gpm of water flow passing through the foam manifold at this instant in time.  MCFRTA 2008

  10. Info Displays - % (Foam Injection Rate) • #’s to right indicate Foam Injection Rate. • Default rate will be 0.3% • Letter to left indicates Foam Tank being used (e.g. “A”)  MCFRTA 2008

  11. Info Displays - Total Flow • Indicates (in gals.) running total of water flowed through Foam Manifold • Starts counting when the system is powered up  MCFRTA 2008

  12. Total Foam • Running total of foam concentrate used (gallons) • Uses • Foam Tank Refill • Insurance Company Reimbursement? • Usage Tracking in Firehouse  MCFRTA 2008

  13. Up and Down Arrows • Adjust Foam Injection Percentage Rates with the Touch of a Button • Range of 0.1% to 10.0% • You will probably not have to change this under normal conditions. Decrease % Increase %  MCFRTA 2008

  14. LED Bar Graph • Visual indicator of Foam Pump capacity being used • Just one LED to left lit up simply means the foam pump is on and supplying concentrate. • If all the LEDs are lit up all the way to the right, that means that all 5gpm capacity of the foam pump has been used up!  MCFRTA 2008

  15. System Zero • To reset Total Flow and Total Foam • Press both arrows simultaneously • This also resets when system is powered down.  MCFRTA 2008

  16. CAFSPro Controller • Power Button • Switch Displays Button • Up and Down Arrows • LED Bar Graph  MCFRTA 2008

  17. Power Button • On/Off Control • Automatic start when engine is put into pump gear • Lit LED indicates power on  MCFRTA 2008

  18. Switch Displays • Switch Between the 4 Informational Displays  MCFRTA 2008

  19. Informational Displays Switch Displays Button • Air Flow (CFM) • Air/Water Ratio • Compressor Temperature • Hours Run  MCFRTA 2008

  20. Air Flow (CFM) • Real Time Air Flow (should be about 1/2 the GPMs of water flow - if flowing wet foam)  MCFRTA 2008

  21. Air to Water Ratio • Ratio of Air Injection to Foam Solution • (CFM air/GPM water) • Ranges from .5 (default setting) all the way to 11  MCFRTA 2008

  22. Compressor Temperature • Temperature in degrees Fahrenheit • Here the controller is indicating 161F degrees. This is a good operating temperature.  MCFRTA 2008

  23. Hours Run • Total Hours the Air Compressor has been running since the system was installed. • This compressor has had 15.7 hours of working time.  MCFRTA 2008

  24. Up and Down Arrows • Adjust air/water ratio • Wet to Dry Range • The more air is added the “dryer” the foam • Never increase the air when crews are engaged in interior attack. Lessen Air “Wet” Add Air “Dry”  MCFRTA 2008

  25. Wet to Dry - Controlled by amount of air “Wet” “Fluid” “Dry” The more air - the “dryer” the foam  MCFRTA 2008

  26. Available Air / Water Mixtures • Wet • 0.5 scfm / 1 gpm (default) • 1.0 scfm / 1 gpm • 1.5 scfm / 1gpm • Medium or Fluid • 2.0 scfm / 1 gpm • 2.5 scfm / 1 gpm • 3.0 scfm / 1 gpm • Dry • 11.0 scfm / 1 gpm  MCFRTA 2008

  27. LED Bar Graph • Visual Indicator of foam consistency (Wet to Dry) Wet >>>>>>>>> Dry  MCFRTA 2008

  28. To Put Compressor In Standby Mode • Compressor is engaged and running • User taps Power Button once • Air Injection Valve then closes & Controller indicates “Stby” • Compressor is still turning • Instant-On if it should be needed  MCFRTA 2008

  29. To Turn Compressor Completely Off • Compressor is engaged and turning • Reduce engine speed to idle! • Push on/off button and hold • 3 Beeps, & Display shows “3,2,1, oFF” • Compressor is now not turning  MCFRTA 2008

  30. User Off Mode • After turning air compressor off, pump would need to be throttled back up to move water • Pump needs to be taken out of gear and re-engaged to bring air compressor back up  MCFRTA 2008

  31. Air Compressor Off When do you need to turn Air Compressor off? • If you need to pump plain water or foam solution above 150 psi • If failure of foam system and safety interlocks occurs - slug flow & chatter • If you run out of foam • If you are going to be only using water and want to avoid adding hours to air compressor.  MCFRTA 2008

  32. Review Questions • How do you know if the foam pump is on? How do you turn it off? • How do you know if the air compressor is on? How do you put the air compressor on standby? What exactly does this mean? • How do you turn the air compressor completely off? When should you turn it off?  MCFRTA 2008
