1. Breakage or Damage During Shipment
The transportation company is fully responsible for all shipping damage and will resolve
problems promptly if you handle it correctly. Please read these instructions carefully.
Examine the contents of all shipping cases. If you find any damage, call your transportation
agent at once and have them make a description on the freight or express bill describing the
damage and the number of pieces. Then write us and we will send you the original bill of lading.
Get a claim blank from the express or truck company. Fill the claim form out. Attach the claim
blank to the original bill of lading together with a copy of our invoice. Attach a memo on which
you show the value of the damaged goods. Mail or hand these papers to your local transportation
agent. They will process your claim with reasonable promptness.
Please note, we cannot and will not enter claims for damages. If we filed claim here, it would be
sent to your local freight agent for verification and investigation. This time can be saved by you
filing the claim directly. Every consignee is on the ground floor, in contact with the local agent
who inspects the damaged goods, and thus, each claim can be given individual attention.
Since our goods are packed to comply with the regulations of all railroad, truck, and express
companies, we cannot allow deduction from any invoice because of any damage, however, be
sure to file your claim promptly. Our goods are sold F.O.B. factory. We take receipt from the
transportation company certifying that the goods were delivered to them in good order and our
responsibility ceases.
It is seldom that any breakage or damage occurs in any of our shipments and in no case will the
customer be out any expense if they follow the above instructions.
Be sure to keep all damaged goods subject to examination of the truck or express company
inspector, who may call on you some time later. These damaged goods, of course, will belong to
them, and they will inform you what to do with them. If you dispose of these damaged goods,
your claim may not be paid.

2. General Description and Specifications
The COMMAND LIGHT Traffic Flow Board LIFT is designed to provide the means to elevate a
high-intensity light bar for emergency scene lighting with quick precision. As with any
electromechanical device, take precautionary steps to assure safe operation.
Never operate the TRAFFIC FLOW BOARD near overhead power lines.
Power for the 12 VDC circuitry is provided by the emergency vehicle generator. All mechanical
actuation power is designed to be powered by the vehicles 12 VDC power supply. The umbilical
corded control unit is powered via 12 VDC eliminating hazardous voltage levels within the hand
held control box.
The COMMAND LIGHT TRAFFIC FLOW BOARD is manufactured to provide years of service
with a minimum of maintenance.
3. Product Safety Precautions
[Never operate the TRAFFIC FLOW BOARD near overhead high voltage power
lines. The TRAFFIC FLOW BOARD is manufactured from electrically conductive
materials.
[Do not use the TRAFFIC FLOW BOARD for uses other than its’ intended purpose.
[Do not move emergency vehicle with the lift extended.
Visually verify that the lift is completely nested before
moving vehicle.
[Do not change lift position while people are located
within its’ operating envelope. There are numerous
pinch points that can cause serious bodily injury.
[The TRAFFIC FLOW BOARD contains automatic
reset circuit breakers. Disconnect power at the generator
distribution panel before servicing the unit.
[Do not use a high-pressure washer or subject the lift to
high volumes of water when cleaning.
[Never use the TRAFFIC FLOW BOARD as a lifting
device or mobile arm.
[Do not use a TRAFFIC FLOW BOARD that has been
damaged or is not fully functional, including non-
working indicator lamps.
[Never hold any part of the TRAFFIC FLOW BOARD with a hand or foot while it
is in motion.
[The TRAFFIC FLOW BOARD has numerous pinch points. Keep loose clothing,
hands and feet clear of moving parts.

4. Operation
Raising the lift from the nested position
Using the control box to raise the lift arm to the desired height. Control switches are of momentary
action style and must be held in the “on” position to actuate the unit.
The TRAFFIC FLOW BOARD has an override system that precludes rotation of the light bar until
the lower stage has elevated ≈24” from the nested position. When the lower stage is below 24” a
mercury switch controls the following:
Arrow board bar is prevented from rotating
Prevents the lift arm from moving down if arrow board is not centered.
Returning the lift to the nested position
The TRAFFIC FLOW BOARD is equipped with an auto park function as a standard feature. The
black button on the control box initiates the auto-park sequence.
Auto-park Sequence
Press black button labeled AUTOPARK once. The button must be held in position to complete the
Autopark sequence. The auto-park sequence begins:
1. Arrow board begins rotation to the center position.
2. Once board is centered, rotation stops, lift arm begins retracting.
3. Release button when lift arm has fully retracted. Actuator has an override
clutch which will provide audible feedback when fully retracted.

5. Installation
The TRAFFIC FLOW BOARD must be installed by a designated installation facility by qualified
personnel only. All safety precautions must be thoroughly understood before installation. Please consult
the factory for additional installation information assistance.
Installation Kit
Included with the TRAFFIC FLOW BOARD is an installation kit. Verify that the contents of the kit
includes the following items:
(1) Pre-wired controller box with pocket
(1) Controller
(2) Cables
(1) 22/20 PVC
(1) 12/2 PVC
(1) Small hardware parts bag with:
(4) mounting spacers ½” thick flat
(4) 5/16-18 X 2 ½” bolts
(4) 5/16-18 nylon lock nuts
(4) 5/16” flat washers
(4) 5/16” fender washers
Tools Required
Lifting device (crane, forklift, block and tackle, etc.)
Sling for lifting
Drill
11/32”drill bit or hole saw
1/2”combination wrench and / or ratchet and 1/2”sockets
Silicone based gasket sealer, RTV™ recommended
The TRAFFIC FLOW BOARD can weigh in excess of 100 pounds when an arrow board is
attached. Use mechanical assistance to position the lift for installation such as a forklift or crane. Use
a sling to grasp the lift.
When routing the connecting electrical wires take care to avoid sharp bends, hot components or other
hazards to the wire.
The TRAFFIC FLOW BOARD is not designed to be operated in a raised position while the vehicle
is in motion. The TRAFFIC FLOW BOARD includes warning circuit wiring to enable a warning
device.
Location Requirements
The TRAFFIC FLOW BOARD will vary in overall size depending upon which arrow board has
been chosen. The TRAFFIC FLOW BOARD frame can be mounted on any location that is 47” x
23”. The surface should be flat or have only a slight crown. For a recessed installation allow for a
minimum of 52” x 24” and a maximum of 5” deep to allow for proper operation.

Four mounting bolt holes are required. Additional holes may be drilled in the frame ends if necessary
to clear obstructions on vehicle.
Access hole for the power cord cabling should be in close proximity to the rear of the lift. The
control box should be mounted in an area shielded from the weather. Allow a minimum of 10”
clearance above the control box mounting location to permit easy removal of the hand controller.
Mounting
Position the frame on top of vehicle roof to use as a template for locating mounting holes.
Remove any obstructions below the mounting surface such as headliners before drilling mounting
holes. Drill 11/32” holes in the mounting surface using the end frame holes as a template.
Attach any necessary lifting attachments to the unit.
Place the provided spacers in the location of the lift mounting holes. The spacers may be modified to
conform to the contour of the mounting location.
Slowly lift the TRAFFIC FLOW BOARD and check for balanced lifting. Lower and make any
necessary adjustments to the lift points.
Lift and place the TRAFFIC FLOW BOARD into position above the spacers. Before placing the full
weight of the unit on the spacers, align spacers with the holes in the end frame.
Fasten the lift using the provided hardware. To assure a weather tight installation apply a thin bead of
silicone based gasket sealer to the base of the spacer and under side of bolt head.
Remove any lifting straps and devices from the lift.

Locate and drill wire feed holes as necessary.
Control Box Pocket Mounting
Using the pocket as a template, mark hole locations.
Drill 1/8” mounting holes. Drill any holes required to route the control wire from the control box
holster to the TRAFFIC FLOW BOARD unit.
Mount pocket with provided hardware.
6. Electrical Wiring
Run the control wire from the control box to the relay box.
Run the power wire from the vehicle 12VDC power source or generator to the TRAFFIC FLOW
BOARD. A 15 Amp breaker is recommended for the TRAFFIC FLOW BOARD.
Make the control connections in the TRAFFIC FLOW BOARD relay box.
Refer to wiring schematic to assist in identifying connections.
7. Maintenance
The TRAFFIC FLOW BOARD is constructed with corrosion resistant aluminum and stainless steel
fasteners. To further enhance corrosion resistance all exposed surfaces receive a powder coated paint
finish. To assure years of trouble free service periodically clean all external surfaces with a mild
detergent solution and a gentle spray of water. Do not use a high-pressure washer, which will force water
into sensitive electric circuitry.
The actuators are sealed units and do not require adjustment or lubrication.
Periodic cleaning of all pivot points on the TRAFFIC FLOW BOARD with a moisture displacing
cleaner and soft bristle brush, without disassembly, to remove accumulated dirt and debris will minimize
wear.
8. Power Failure
The TRAFFIC FLOW BOARD can be retracted manually if power to the unit is lost. If power loss
is temporary, reestablishing power may be easier than manually retracting the lift.
If this is not feasible it is recommended that you disconnect 12VDC power sources from the
TRAFFIC FLOW BOARD before proceeding.
Remove the arrow board actuator first.
