Foam Pump Operation
Upon power up, the software revision number will be dis-
played. The unit will then display the flow rate.
Because the conductivity measurement for a given per-
centage mix changes with the flow rate, the calibration
data is stored in an array. The array holds entries for the
various parameters at several different flow rates that are
in between flow rates entered in the data array.
Figure 2. Operator Interface Terminal
IL2963
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 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
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 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 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 default %.
FOAM
Pressing the FOAM key will alternately start and stop the foam operation. When the control-
ler is running, the FOAM LED will be lit. The FOAM LED will blink when the motor control
output is active. The LED will be lit and not blink during the initial pump delay, or when the
system is on, but no water flow is detected.
If flow is detected, and one or both of the sensor inputs reads full scale, an open sensor error
will be flagged. The error SEn1 or error SEn2 will be displayed when the FOAM button is
pressed to indicated that the system is non
−
functional. In this case, the Manual Mode will be
functional and must be used.
MANUAL MODE
If the display is showing the flow rate and the two ARROW keys are pressed simultaneously,
the % MIX LED will be lit 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.
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 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.
