ABSTRACT
The goal of preventive maintenance is to maximize the useful life of equipment. A good preventive maintenance program requires an investment in time and effort in order to avoid costly repairs before the equipment malfunctions. Before attempting any diagnostics, troubleshooting, or repair be sure to disconnect power from the fixture. Troubleshooting to the component level usually requires a set of schematic diagrams, an oscilloscope, a soldering station, and possibly other more specialized test and repair equipment that an automated lighting technician normally does not carry in the field. There are two hazards associated with lamps in regard to eye and skin protection; the hazard of lamp explosion and the risk of ultraviolet burns. If a luminaire has an arc lamp it's important that it is properly aligned in the reflector, or the focal point might be positioned in such a way as to concentrate the heat enough to damage optical components.
