Installation and Operation Manual
NOTE: Do not mount radio transmitter or
transmitter cables in direct or close contact with
the FoamPro units.
•
Use care when installing molded cables. Count
pins or check color codes before connecting. Bent
pins caused by improper hookup can prevent
proper operation even when cables are reattached
properly.
• Before connecting the molded cables, inspect the
seal washer in the female connector. If the seal
washer is missing or damaged water can enter the
connector and cause corrosion of the pins and
terminals that will cause system failure.
CAUTION: The cables shipped with each FoamPro
system are tested at the factory with that unit.
Improper handling and forcing connections can
damage these cables and could result in other
system damage.
CAUTION: Always disconnect the ground straps,
electrical wires and control cables from the Digital
Display Control Module and other FoamPro
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.
Digital Display/Control Module
The Digital Display Control Module is designed to be
mounted in the operator panel of the apparatus. The
cutout that will be needed in the operator panel is a
3-7/8 inch (98 mm) diameter hole [(the same as a 3-1/2
inch (89 mm) pressure gauge]. The display is secured
with four #10 studs on the back of the front plate (see
Section 15 for a mounting template). The display
requires 5 inches (127 mm) minimum clearance from
the back of the operator panel to clear wires and
connectors. Make sure there is enough clearance
behind the operator’s panel for the cables. Once the
Digital Display Control Module is mounted, connect the
control cable (red coded cable ends) from the hydraulic
pump valve driver box terminal (See Figure 9-2) to the
5-pin connector on the back of the Digital Display
Control Module (See Figure 9-3). A color-coded decal
on the valve driver box identifies each cable
connection.
NOTE: Ensure that the panel where the Digital
Display Control Module is mounted has an
adequate ground. For stainless steel and vinyl-
coated panels, a ground strap must be attached
from one of the four screws holding the Digital
Display Control Module in place to the frame of the
fire truck to ensure adequate grounding (See Figure
9-3).
Flowmeter Connections
FoamPro Flowmeter
If a single FoamPro paddlewheel-type flowmeter is to
be used, a molded cable is supplied which connects
from the flowmeter sensor to the 3-pin connector on the
Digital Display Control Module (See Figure 9-3).
