ELECTRICAL INSTALLATION
ELECTRICAL CONNECTIONS
Complete system electrical diagrams are
provided at the end of this manual section.
Refer to these diagrams for proper hookup
of each of the electrical components. The
Hale FoamLogix system is designed to be
installed with a minimum of electrical
connections. Complete electrically
shielded cables are provided with each
Hale FoamLogix system to make the
flowsensor, control unit and distribution box
connections. The system installer must
supply primary power wire, low tank level
sensor wire and flat braided ground straps.
ELECTRICAL INSTALLATION CAUTIONS
• To prevent system damage or electrical
shock the main power supply wire will be
the last connection made to the Hale
FoamLogix distribution box.
• The cables provided with each Hale
FoamLogix system are shielded
assemblies. Never attempt to shorten or
lengthen the cables. If necessary order
longer or shorter cables from Hale
Products to suit the particular installation.
• The cables are indexed so they only go in
the correct receptacle and they can
only go in one way. When making cable
connections DO NOT force mismatched
connections as damage can result in
improper system operation.
• The system can only perform when the
electrical connections are sound, so
make sure each one is correct.
• Hale FoamLogix systems are designed for
use on direct current, negative ground
apparatus electrical systems only.
• Do not mount radio transmitter or
transmitter cables in direct or close
contact with the Hale FoamLogix unit.
• Before connecting the cables inspect the
o-ring seal in the female connector. If
the seal washer is missing or damaged,
water can enter the connector causing
corrosion of the pins and terminals
resulting in possible system failure.
• The cables shipped with each Hale
FoamLogix system are tested at the
factory with that unit. Improper handling
and forcing connections can damage
these cables which could result in other
system damage.
• The ground strap must be a minimum of
1-¼ inches (32 mm) wide and no longer
than 18 inches (457 mm). A longer
ground strap must be wider or a double
thickness strap must be used. Make sure
the ground strap is attached to the
chassis frame. Grounding to the body IS
NOT acceptable.
• Always disconnect the power cable,
ground straps, electrical wires and cables
from the control unit or other Hale
FoamLogix equipment before electric
arc welding at any point on the
apparatus. Failure to do so will result in a
power surge through the unit that could
cause irreparable damage.
• There are no user serviceable parts inside
Hale FoamLogix system electrical/
electronic components. Opening of
these components (distribution box or
control unit) will void warranty.
• When an inline current shunt ammeter is
installed on the apparatus power filter kit
(Hale P/N 546-1870-00-0) on the Hale
FoamLogix foam pump.
CONTROL UNIT
The control unit mounts in the operator
panel of the apparatus. The display is
secured with four #10 socket head screws in
