Bar Graph
(See Figure 5-1: “Control Unit Identification,” on page 121.)
The bar graph consists of a ten (10) LED array. When the ON button is
pressed the left-most LED illuminates to indicate the system is ON and
ready to inject foam concentrate.
When water is flowing, the LEDs to the right on the bar graph illuminate indi-
cating foam concentrate is being injected. The number of LEDs illuminated
indicates the approximate pump capacity being used (percentage of foam
being pumped).
If the water flow requirements exceed the capacity of the pump, the pump
speed increases to its maximum rate. All bar graph LEDs illuminate and the
right-most LED FLASHES, warning the operator that the system capacity is
being exceeded and the system is running “lean” on foam concentrate per-
centage.
If the flow decreases such that the required injection rate is less than the
lowest rating of the pump, the pump speed decreases to its minimum rate.
The first bar graph LED to the left FLASHES, warning the operator that the
system capacity is being exceeded and is running “rich” on foam concen-
trate percentage.
5.3 RESET FUNCTIONS
The totalized values for water and foam concentrate being pumped are
cleared from memory by performing the RESET function.
1. Using the DISPLAY button ( i ), select either TOTAL WATER or TOTAL FOAM.
2. By pressing and holding both the and buttons simultaneously, the value
shown is cleared and the display shows zero (0).
3. Additionally the totalized values for the water and foam concentrate reset to
zero (0) automatically when the apparatus power is turned OFF.
5.4 FOAM CONCENTRATE INJECTION RATE
When % FOAM is selected, the or buttons respectively increase or
decrease foam concentrate percentage.
