Flashers and Tower Lighting Controls Tower and Obstruction Lighting Controls PCR SERIES Photo Control Description The PCR Series of photo controls is a combination of precision electronic circuitry, electromechanical output, and unique molded plastic housing. Designed and built to meet the demands of the most rigorous requirement of tower and obstruction lighting control, each unit is factory calibrated to meet FAA and FCC specifications. Electronic circuit, output contactor, and terminal block are all contained within front plastic housing. Edge support molded into the bottom edge of housing allows easy wiring of new and existing installations. Available with or without cast aluminum junction box. Operation When the amount of light sensed falls below the actuation level Wiring Diagram for energization, the output relay energizes. Conversely, when the amount rises above the actuation level for de-energization, the output relay de-energizes. Dashed lines are internal connections. Features & Benefits FEATURES BENEFITS ABS plastic housing with Withstands outdoor environmental hazards and gasket seal protects circuitry from moisture damage Allows direct control of a lighting circuit without a Two 20A relay contacts separate contactor Fixed time delay Eliminates contact chatter Provides automatic lighting circuit operation from Reliable photo sensor dusk to dawn Ordering Information REPLACES Dashed lines are internal connections.
