The sensor can also help ensure safety by allowing lights to be turned on when the ambient light falls below a specified level. The unit comes in a rugged and watertight UV-inhibited polycarbonate enclosure with an IP66, NEMA 4 rating. The light level range is available as Foot Candle and Lux with 0 to 5V, 0 to 10V or 4 to 20 mA output. Custom ranges are also available. The BAPI Outdoor Light Level sensor should be mounted on top of a building or structure in direct sunlight with a North facing orientation. This probe is fitted with 1/2 inch NPSM threads on the base to easily screw into a conduit fitting. The installer should check the surrounding area in order to identify any obstacles (such as tree shade) which may inhibit the light sensor readings negatively and choose an appropriate location accordingly. Mount the unit so that other equipment on the building cannot physically or mechanically obstruct it. Do not mount under awnings or other projections within 15 feet, to keep the sensor free from shade. If the unit cannot be roof mounted with an unobstructed view of the horizon, then do not mount near economizers, intake or exhaust fans, barometric dampers or other reflective surfaces. To further minimize obstructions and shading, do not mount near building corners. Mount near the center of the building away from balconies and opening windows. Mount at least 24 inches from the wall. Mounting Fig. 1: Sensor mounted in a parking lot facing north.
