General Description and Specifications

The TFB-H7 is designed to provide versatile traffic control with quick precision. As with any electromechanical device, take precautionary steps to ensure safe operation.

Model #	Description Minimum Power Requirements
TFB- H7	Horizontal Flow Board 28 Amps, 12 VDC

The vehicle provides power for the 12 VDC circuitry. The umbilical corded control unit is powered via 12 VDC eliminating hazardous voltage levels within the hand held control box. The TFB-H7 is manufactured to provide years of service with a minimum of maintenance.

Operation

Raising the tower from the nested position

Using the control box, raise the lower stage. Control switches are of momentary action style and must be held in the “on” position to actuate the stages. The TFB-H7 has an override system that precludes rotation of the flow board until the lower stage has elevated substantially enough from the nested position. When the lower stage is below this safety limit, the following conditions exist:

Flow board is prevented from rotating.
Prevents the lower stage from moving down if flow board is not centered.

Returning the tower to the nested position

The TFB-H7 is equipped with an Autopark function as a standard feature. Releasing the Autopark button acts as an “Emergency Stop” and will cancel the Autopark sequence.

Autopark Sequence

Press and hold the black Autopark button on the controller. The Autopark sequence begins:

Flow board begins rotation to the center position.
Once flow board is centered, rotation stops, green center indicator illuminates,and the lower stage begins retracting.
After lower stage has fully retracted, red nest indicator and flow board will be extinguished.

Installation

The TFB-H7 must be installed by a designated installation facility or by an EVT certified Level FA4 Technician. All safety precautions must be thoroughly understood before installation. Please consult the factory for additional installation information assistance.

Improper installation can cause overheating of electrical power wires that could catch fire and void the warranty.
Ensure all wiring is properly protected with correct sized breakers and fuses before connecting to the power source.
Verify all connected electrical components are able to handle the load for this light tower as listed in the Technical Specifications.
If in doubt, contact Command Light at 1-800-797-7974 or info@commandlight.com.

Installation Notes

The TFB-H7 weighs approximately 136 pounds. Use mechanical assistance such as a forklift or crane to lift the light into installation position.
Use the provided fender washers under the mounting surface to distribute the weight load evenly.
When routing the connecting electrical wires take care to avoid sharp bends, hot components or other hazards to the wire.
The TFB-H7 is not designed to be operated in a raised position while the vehicle is in motion. The TFB-H7 includes warning circuit wiring to enable a warning device.

Location Requirements

The standard TFB-H7 can be mounted on any location that is 49” x 24”. The surface should be flat or have only a slight crown. For a recessed installation allow for a minimum of 66” x 56”. Consult with factory before construction of recessed installation. Verify all dimensions before installation to assure proper operation of light will not infringe on other installed components. For all other installations refer to the dimensional drawing included in this guide that represents your particular model of tower. The drawings reflect the dimensions of the “working envelope” of a typical tower. Endure sufficient clearances are incorporated in your installation to allow for variations (vehicle body flex, environmental conditions, future servicing needs, etc.)

Four mounting bolts are required. Additional holes may be drilled in the frame ends if necessary to clear obstructions. Access holes for the power cord cabling should be in close proximity to the entrance box on the tower. Installing the cords with a sweeping 90° or 180° bend will provide better results. The control box holster should be mounted in an area shielded from the weather. Allow a minimum of 10” clearance above the control box holster mounting location for easy access to the controller.

Mounting

Place the provided spacers in the location of the tower mounting holes. The spacers may be modified to conform to the contour of the mounting location.
Remove any obstructions below the mounting surface such as headliners.
Attach any necessary lifting attachments to the TFB-H7.
Slowly lift the TFB-H7 and check for balanced lifting. Lower and make any necessary adjustments to the lift points.
Lift and place the TFB-H7 into position above the spacers. Before placing the full weight of the tower on the spacers, align spacers with the holes in the end frame castings.
Drill 21/64” holes in the mounting surface using the end casting holes as a template.
Fasten the tower 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 underside of bolt head.
Remove any lifting straps and devices from the TFB-H7.
Locate and drill the wire feed holes.

Control Box Holster Mounting

Using the holster as a template, mark locations of holes.
Drill 17/64” mounting holes.
Drill any holes required to route the control wire from the control box to the TFB-H7. Mount holster box with provided hardware.

Electrical Wiring

Please Note: Detailed internal wiring schematic for the tower is found in the pages at the end of this document.

Run the control wire from the control box holster to the TFB-H7.
Run the power wire from the breaker box or generator to the TFB-H7. A 30 Amp breaker is recommended on a TFB-H7.
Make the control cable connections in the TFB-H7 relay box by matching each control wire to its same color on the connector block of the TFB-H7 relay box.

Warning Device Installation

The TFB-H7 nest sensor can be used to activate a warning device when the light is extended. Typically the vehicle will have a light or buzzer that activates when the compartment doors are open. The connector for hooking up a warning device is located in the holster box that holds the controller.

Maintenance

Cleaning

The TFB-H7 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. Lamp lenses may be cleaned with any commercially available glass cleaner. The actuators is a sealed unit and does not require adjustment or lubrication. They also have a slip-clutch to compensate for minor stroke tolerances at the limits of its travel as well as internal limit switches. The actuator may produce a ratcheting sound at each end of the stroke which is normal. The actuator should not be made to ratchet excessively, this can lead to premature actuator clutch failure. All pivot points on the TFB-H7 have self-lubricating thermal polymer or brass bushings. Periodic cleaning with a moisture displacing cleaner and soft bristle brush, without disassembly, to remove accumulated dirt and debris will minimize wear.

Power Failure

The TFB-H7 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 tower.

Disconnect power source from the TFB-H7.

Rotate to Center

Locate the silver plug located on the actuator below the actuator’s motor. Use the provided hex tool (6mm hex bit) to remove silver plug. Be sure to not lose this plug. Use the same hex tool inserted into the opening to drive the internal gears of the actuator. Be sure to replace the silver plug after this actuator is adjusted to center.

Retract the Lower Stage

Due to structural needs, the lower actuator cannot be manually adjusted. To lower the tower, first ensure flow board is rotated as close as possible to center to avoid impacts. At least one person must hold the flow board to prevent it from dropping. Once the weight of the flow board is relieved from the lower actuator, remove the pin attaching it to the base by removing one of the E-Clips on the lower actuator pin. Using a brass pin, drive the actuator pin out, again, making sure the weight of the flow board is held by assistants. Once the end of the actuator is free from the base, lower the flow board until it seats as much as possible. Strap the flow board down for transportation.

Troubleshooting

*Problem*	*Possible Cause*	*Solution*
Unit will not extend	No power to the unit	Check power input connections.

Ensure 30 Amp input breaker has not been tripped.
Incorrect installation| Refer to installation instructions.
Upper stage will not rotate| Lower stage not raised above safety limit| Raise lower stage higher.
Rotation motor failure.| Consult with factory.
Flow board will not illuminate| Circuit breaker tripped.| Check circuit breaker at power supply.
No power to the unit.| Check power supply operation/output.
Unit will not nest| Flow board not centered| Raise lower stage higher. Center flow board (green light illuminated)
Unit being operated on a slope >15°| Level Truck. If problem persists, rotate flow board to center, using a pike pole, hold unit centered while lowering to nest position.
No rotation| Check safety limit sensor, bad, etc.| Contact factory for replacement part.
Autoparking off Center| Center switch out of adjustment| Contact factory for replacement part.

Override Circuit

The TFB-H7 has an override circuit to allow the user to lower the tower no matter what state the sensors or rotation actuator are in. This is a failsafe for if a sensor fails in the field and the tower still has power. Ensure the flow board is centered as closely as possible, and all users are clear of pinch points. Disconnect the rotation actuator after flow board is centered. If the rotation actuator has failed, either manually rotate to center as in the power failure section or disconnect the rotation actuator. To activate the override circuit, hold both the Auto Park button and the actuator lift switch in the down position. After 5 seconds, the lower actuator will retract while both switches are held and stop upon release.
