FLOODLIGHTS

The floodlight unit (fig. 14-27), commonly known as a light plant, is intended for field use in all climates. Being self-contained, it is especially suited for use in remote locations as an emergency floodlight source.

Components

The light plant unit consists of an engine generator set, portable floodlights, extension cords, floodlight mounts, and a grounding rod. The floodlights, extension cords, floodlight mounts, and the grounding rod are all accountable collateral gear, assigned to each unit; therefore, it is important that these components are returned and stored in their assigned light plant. All of the components are mounted on a two-wheel trailer, covered by a weatherproof sheet metal housing.

Mounting provisions for the floodlights are provided inside the housing. The floodlights swivel in different positions for distributing light over a large area. Extension cords are supplied for using the floodlights away from the unit. Special plugs are used on these extension cords that are for use only with the floodlight.

NOTE: Do NOT run power tools from a light plant. The power surge and power draw from these tools can overload the exciter and result in damage to the generater.

Operation

Before placing the light plant in operation, make sure the unit is grounded, using the grounding rod and grounding cable. Additionally, ensure the light plant is positioned suitably for adequate operating room and ventilation for dissipation of engine heat and exhaust. Remove the number of floodlights and cables required and place them in the desired locations. Plug the cables into the output receptacles.

Do NOT idle the engine with the generator excited. If the engine is idled with the generator excited, excessive field current may burn out the generator field winding.

Safety

Safety is a vital part of floodlight operation. Many floodlight safety practices are simple and obvious. Major safety precautions applicable to floodlight operation and care are as follows:

• Always pipe exhaust fumes outside when operating a floodlight unit in an enclosed area.

• Always ground the unit before it is placed into operation.

• Always stop the unit before servicing with fuel or lubricants.

CAUTION

Do NOT shut the engine down when the generator is under load. If you are not qualified to secure the generator, find someone who is.

• Do not allow extension cords to contact sharp objects, oil or grease, hot surfaces, or chemicals.

• Extension cords should not be allowed to kink or be left where they might be run over.

• Replace damaged cords. They are NOT to be patched with tape.

• Store cords in their proper place, coiled loosely.

• Wear hearing protection when in the vicinity of a running generator.

• Do not attempt to install, hook up, or place any electrical apparatus when your hands are wet or when you are wearing wet clothing or shoes.

• Whenever it becomes necessary to check a circuit, have a Construction Electrician (CE) do this with appropriate testing equipment.
