Assembly and Installation

Installing the ground ring assembly requires these tools:
1/4-in spacers (3)
Hand drill
5/32-in drill bit
#3 Phillips drive bit
Small square
#14 x 1 wood/metal screws
The turntables each have two floor flange pieces. All flanges are pre-cut at the
factory for a drop-in fit.
1.
Lay the floor flange into the opening of the raised floor and push outward
to the diameter of the opening.
2.
Attach the turntable top onto the center bearing with the hardware
provided.
3.
Using a pipe clamp and 1/4-in Allen wrenches or 1/4-in pin, place a
spacer between the turntable and floor flange starting in three places in
the center or on the flange.

Assembly and Installation
4.
Once tension is placed on all three wrenches, drill a 5/32-in hole through
the counter-sunk holes in the floor flange. Drill completely through the
panel and place screws into the holes.
5.
Continue working around the floor flange, completing two or three holes
at a time.
Make sure that a 1/4-in gap between the turntable top and the mounted brush
ring be held as close as possible so that the grounding brushes seat properly.
Also, make sure the flange ends are flush with each other.
6.
Continue mounting until all screws are installed. Some screws may fall
between the floor panel joints. Try to position the flanges, making sure as
few screws hit these points as possible, and making sure that the first or
last hole in the flange is not too close to one of these joints. Trim the top
floor joint strips to fit up against the flange.
Floor Flange Installation in a Concrete Pit
Installing in a concrete pit is the same as a paneled floor, with the exception of
the mounting hardware. Instead of the #14 x 1-in square socket flat head screws,
use 1/4 x 1.75-in Phillips flat head concrete anchors.
These tools are required for the next stage of installation:
1/2-in hammer drill
3/16 x 3.5-in hammer drill bit, at minimum
Vacuum to clean inside the drilled holes for maximum thread
engagement
When drilling holes, be aware of buried conduit and pit drainpipes. Drill 3/16-in
holes, two inches minimum depth.

1.
Choose a location for the IR infrared sensor that is away from traffic.
2.
Using a 1-in hole saw, cut an opening in the floor for the IR sensor.
3.
Connect the

4.
Use the 1/16-in drill bit and four flathead mounting screws to mount the
IR sensor collar.
5.
Connect the
V+
,
GND
, and
SIG
wires from the IR sensor to the
IR-100 control unit as shown in the diagram.
6.
Using adhesive tape, attach the IR flasher LED directly over the IR input
on the motor control box.
7.
Connect the IR flasher to port 1 on the IR-100 control unit.
8.
Plug the 9–12VDC power supply into the power connector on the
IR-100 control unit, and then plug the power supply into a 120 VAC
outlet.
