SUCTION STREETSIDE
The streetside suction inlet shall be equipped with a 6" mechanically actuated valve installed on the pump inlets. The
valves shall be mounted behind the side panels and shall be controlled by a hand crank adjacent to the inlets. The valves
shall have open and closed indicators. The suction shall terminate with a 6" NSTM. One (1) 6" NSTF x 5" Storz elbow and
5" Storz cap shall be provided.
SUCTION CURBSIDE
The curbside suction inlet shall be equipped with a 6" mechanically actuated valve installed on the pump inlets. The
valves shall be mounted behind the side panels and shall be controlled by a hand crank adjacent to the inlets. The valves
shall have open and closed indicators. The suction shall terminate with a 6" NSTM. One (1) 6" NSTF x 5" Storz elbow and
5" Storz cap shall be provided.
ADVANTUS 3 FOAM SYSTEM DETAILED SPECIFICATIONS
The apparatus shall be equipped with an automatic microprocessor controlled, conductivity based, direct injection,
discharge side foam management system. The installed system shall be capable of accurately injecting all commercially
available Class A foam concentrates and most Class B foam concentrates. The foam injection and mixing operation shall
utilize electrical conductivity and temperature measurements of the clear water and foam solution as well as measured
water flow to provide highly accurate and consistent mix ratios within the specified flows and pressures. The system must
be accurate over the specified operational range when installed according to the instructions contained in the factory
supplied installation manual.
Microprocessor Controller
A 16-bit mixed signal microcontroller with 60 kB flash memory, 2 kB RAM and 12-bit analog to digital converter shall be
utilized to receive input from the incoming water conductivity probe, temperature sensor, flowmeter and foam solution
conductivity probe, compare values and control the foam pump motor, providing accurate injection into the foam process
manifold per the operator selected mix ratio. The controller and related electronics shall be located inside a sealed
aluminum housing which is mounted to the motor/pump mounting base plate. All electrical components of the foam
system shall be sealed to NEMA 4X standard or equivalent, suitable for mounting inside the apparatus pump
compartment.
Operator Interface Terminal
The system shall be equipped with an operator interface terminal (OIT) which shall be mounted on the pump operator’s
panel. The OIT housing shall be constructed of aluminum with a chrome plated finish. A UV stable polycarbonate overlay
with integral labeling shall be provided on the face of the OIT. The OIT shall be fastened to the pump panel with four
stainless steel, swing-out, self adjusting compression latches which eliminate the use of screws, nuts or bolts in the
attachment. The digital display shall consist of four .56” high digits, each with seven segment ultra-bright LED’s and
seven ultra-bright status LED’s. Four flush mounted pushbutton controls shall be provided on the control face which are
constructed of stainless steel and designed for millions of cycles in severe duty applications. The OIT shall enable the
pump operator to perform the following functions for the foam system:
Provide push-button control of foam ratios from 0.1% to 1%, in 0.1% increments; 3% and 6%
Show current flow-per-minute of water
Show total volume of water discharged during and after foam operations are completed
Show total amount of foam concentrate used
Show which foam supply tank is in use
Perform setup and calibrate functions for the microcontroller
Flash a “low concentrate” warning when the foam concentrate tank(s) run(s) low
Flash an “error” warning with associated code in the event of an electronic malfunction
Provide a manual back-up mode, controlled by the operator
