TYP. Schematic E05 Rev 3.pdf

This is a technical schematic diagram for a motor starter component key. The document illustrates the electrical wiring configuration and interconnections for a mechanical draft hybrid wood cooling tower designed for NIST Research Reactor Project 2. The schematic displays multiple terminal points, switch returns, and unit switching arrangements across several functional zones, with connections to command systems, unit limit switches, closer limit switches, and proximity switches. The component key legend on the left side provides detailed cross-references for various electrical components including open commands, close commands, open returns, close returns, and limit switch operations across different terminal blocks designated as T63_01 through T63_32. The diagram includes grounding connections (GRND), terminal designations (L, T, C, F4), and reference markers for capacitors (C1, C2), a resistor (R), and an inductor (T2). The engineering drawing was prepared by BDT Engineering for Birdorf-Burr, Inc., with the NIST identification number 325N5JC1028 and drawing reference CT1047. This appears to be a technical specification document supporting the procurement or documentation of motor starter equipment rather than a solicitation or contract opportunity document.
