Foam Pump Operation
Upon power up, the software revision number will be dis
played. The unit will then display the flow rate.
The software will perform a linear interpolation to determ
ine values to use for flow rates that are in between flow
rates entered in the data array.
Figure 2. Operator Interface Terminal
IL3437
During normal operation, the OIT (Operation Interface Terminal) will display flow rate, percent mix, total water or total
product.
SELECT
Selects data to display. The default is to display flow rate. Pressing the SELECT button will
scroll through the list, then wrap back around to the top of the list. The associated LED will
light to indicate what data is being displayed.
Flow Rate
Mix Percentage
Total Water
Total Product
Holding the SELECT button for more than two (2) seconds will lock the display to the current
position. Pressing the SELECT button again will unlock.
UP ARROW
When the Mix Percentage is displayed, the current mix setpoint will be displayed. Sub
sequent presses of the UP ARROW button will increase the Mix Setpoint by 0.1%. After a ten
(10) second timeout, the display will return to the Flow Rate display.
DOWN ARROW
When the Mix Percentage is displayed, the current mix setpoint will be displayed. Sub
sequent presses of the DOWN ARROW button will decrease the Mix Setpoint by 0.1%. After
a ten (10) second timeout, the display will return to the Flow Rate display.
Pressing both UP and DOWN simultaneously when the Total Water is displayed resets the
Total Water accumulator to Zero.
Pressing both UP and DOWN simultaneously when the Total Product is displayed resets the
Total Product accumulator to Zero.
Pressing both UP and DOWN simultaneously for two (2) seconds, when the Flow Rate is
displayed enters the MANUAL mode of operation. See Manual Mode operation below.
Pressing both UP and DOWN simultaneously while in Mix % will go to the preset default %.
FOAM
Pressing the FOAM button will alternately start and stop the foam operation. When the con
troller is running, the FOAM LED will be lit. The FOAM LED will blink when the motor control
output is active.
MANUAL MODE
If the display is showing the flow rate and the two ARROW keys are pressed simultaneously,
held for two (2) seconds, the % MIX LED will light and the display will show a default value of
2.0. Use the UP and DOWN arrow keys to increase or decrease this value in steps of 0.5.
NOTE: Pump output is based on a theoretical ratio of foam to water at 50 GPM.
Pressing both ARROW keys again exits the MANUAL mode and stops the pump.
While in manual mode, you can pause the motor by pressing the RED FOAM button (once).
You can increase or decrease the foam percentage at this time. Resume foam flow by press
ing the RED button once.
Pressing both ARROW keys again exits the MANUAL mode and stops the pump.
NOTE: Motor/Pump Assembly will operate in MANUAL mode whether or not there is a
water flow. If the INJECT/BYPASS valve is in the INJECT position, foam concentrate
will be injected into the system, which will waste foam concentrate.
AUTO RUN
The system is equipped with an AUTO RUN feature. If the voltage (+12 or 24 VDC) is ap
plied to position 1 on the terminal strip, it will have the same effect as pressing the Red
FOAM button. This will start the Foam system. The system will not inject foam until water is
flowing.
