Grey Rd Communication diagram - UIS.pdf

This document is an electrical wiring and interconnection diagram for a Grey Road Lift Station prepared by UIS Programmable Services Inc., associated with a sanitary lift stations generator installation project in Michigan. The schematic details a comprehensive electrical control system using a SLC 500 programmable logic controller (PLC) with multiple input/output connections for pumps, sensors, and alarm systems. The diagram shows voltage configurations for two pump starters, field wire connections, and a detailed layout of terminal strips (TS1 and TS2) with an approximate space requirement of 17" wide x 21" high for the Hoffman A24P20 back plate.

The technical drawing indicates a complex electrical control infrastructure for a municipal infrastructure project, specifically focused on lift station automation and monitoring. The diagram provides precise wiring details for various electrical components, including pump controls, status indicators, alarm systems, and power connections across 120 VAC circuits. The document is dated with revision dates of 12-22-97, 12-23-97, and a final revision on 01-05-98, suggesting this is a detailed engineering specification for a municipal utility infrastructure upgrade or installation project in Michigan.
