OPERATING INSTRUCTIONS
the water flowmeter will display the current flow
rate of the water.
If water flow requirements exceed the capacity
of the pump to deliver foam concentrate, the
pump will run at maximum rate and “
HI FLO ”
will flash on the Digital Display Control Module
so the operator realizes that the system
capacity is being exceeded.
If the flow decreases such that the required
injection rate is less than the lowest rating of the
pump, the pump will run at its minimum rate and
" Lo.Flo " will flash on the display so the operator
will know the system is running rich on foam
percentage.
DISPLAY INFORMATION
The five digit display on the Digital Display
Control Module shows the value of the selected
display function or provides warnings to the
Figure 26. Digital Display Control Module Operation
NORMAL SYSTEM OPERATION
Once the system has been set up and
calibrated, operation is very simple and is
controlled by the buttons on the Digital Display
Control Module (see Figure 26). For setup and
calibration instructions, see Section 9.
When the “FOAM” button is pressed, the “ON”
status lamp will illuminate, indicating that the
system is ready. The “ON” status lamp will flash
when foam is being injected. The FoamPro
system will monitor the water flows and control
foam injection at the specified concentrate
injection rate. The system responds to
variations in water flow by increasing or
decreasing the speed of the foam pump. When
the "FOAM" button is again pressed, the “ON”
status lamp will extinguish, indicating that the
system is in Stand-By mode and the pump will
stop but other system monitoring functions will
continue. Without foam concentrate injection,
