FoamLogix, Model 2.1A and 1.7AHP Class
“A”
Electronic Foam Proportioning Systems

Motor Ground / Primary Power
CAUTION!
CONNECT THE PRIMARY POSITIVE LEAD FROM
THE TERMINAL BLOCK TO THE MASTER SWITCH
TERMINAL OR RELAY TERMINAL USING MINIMUM 8
AWG TYPE SGX (SAE J1127), CHEMICAL RESISTANT,
BATTERY CABLE AND PROTECT WITH WIRE LOOM.
PREVENT CORROSION OF POWER AND
GROUND CONNECTIONS BY SEALING THESE
CONNECTIONS WITH THE SILICONE SEALANT
PROVIDED.
Ground Connection
Be sure the Hale FoamLogix system is grounded to
the chassis. Use a short length of wide flat ground
strap at least 1-
1/4” (32 mm) wide and less than 18”
(457 mm) long to reduce the potential of RFI emitted
by this connection.
A stud is located on the mounting base to attach
the chassis ground strap to the Hale FoamLogix
system. (See Figure 21:
“System Power and Ground
Connections” on page 45.)
When making the ground strap connections
make sure lugs are soldered to the strap ends
for trouble free connections. Seal all connection
against corrosion.
When the length of the ground strap exceeds
18”
(457 mm) use a wider strap or a double thick strap.
CAUTION!
DO NOT CONNECT THE MAIN POWER LEAD TO
SMALL LEADS THAT ARE SUPPLYING SOME OTHER
DEVICE, SUCH AS A LIGHT BAR OR SIREN. THE
HALE FOAMLOGIX MODELS 2.1A AND 1.7AHP
REQUIRE 40 AMP MINIMUM CURRENT.
Primary Power Supply Connection
Make sure adequate switched electrical power from
the b terminal to the battery connection stud
on the motor controller box is provided. (See Table
6: “Recommended Primary Power Cable Sizes” on
page 33.)
Use 8 AWG minimum type SGX (SAE J1127)
battery cable directly to the battery, battery switch or
solenoids for cable runs up to
6’
(1.8 meters) long. Longer wire runs may require
larger battery cable for proper operation. DO NOT
connect power to the same connection as the
pump primer.
RFI/EMI
Electrically shielded cables for control unit and
flow sensor are provided with the Hale FoamLogix
system. The cables are 100% electrically shielded
to eliminate the potential problem of EMI/RFI.
Proper installation of system components and
cables along with proper grounding will limit radio
interference caused by the Hale Foam-Logix
system. Additionally, make sure radio cables and
hardware are not located in the immediate area
where Hale FoamLogix equipment 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 shortened, various lengths of cable are
available to minimize the
“extra” cable in the truck.
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 22:
“Extra Cable Storage” on page 47.)
