Proper installation of system com-
ponents and cables, along with
proper grounding, limits radio inter-
ference caused by the Hale Foam-
Logix system. Additionally, make
sure radio cables and hardware are
not located in the immediate area
where the FoamLogix system is
mounted.
Making round coils of extra control
and flow sensor cables in the pump
compartment can act as an
antenna. While the control and
flow sensor cables cannot be short-
ened, various lengths of cable are available to minimize the “extra” cable in
the apparatus.
When routing control and flow sensor cables take care to avoid routing them
next to antenna wires, radio power lines and radio components. When
there is extra cable, double the cable back on itself and secure with plastic
wire ties in a flat bundle instead of making a round coil. (See Figure 3-36:
“Extra Cable Storage.”)
Make sure the flow sensor tee is grounded. If metal piping is used sufficient
grounding may be present. However, Victaulic joints, plastic pipe and rub-
ber mounted pumps interfere with proper grounding and an additional
ground strap may be required. If necessary, connect a flat braided ground
strap at least 1/4” (7mm) wide from the flow sensor tee to the apparatus
frame to ensure proper grounding.
The #6-32 UNC screw that holds the spade terminal to the flow sensor tee
can be used to attach the ground strap to the tee. (See Figure 3-13: “Flow
Sensor/Saddle Clamp Installation” on page 65.)
Flow Sensor Connections
The control cable harness (connector C3) connects to the 3-pin connector
on the flow sensor. For cable harness overviews, see Section 9 “ 9 Plate
Drawings,” on page 170.
“Low Level Sensor” Installation (Foam Tank)
The foam low tank level sensor(s) must be installed and wired to monitor the
foam concentrate level. (See Figure 3-37: “Low Level Sensor Mounting
Options” on page 93.)
