1 Introduction
CoreSense is an ingredient brand name for compressor electronics associated with Emerson‟s Copeland® brand
products. CoreSense technology uses compressor as a sensor to unlock information from within the compressor
providing value added features such as advanced motor protection, diagnostics, communication.
With active protection, advanced algorithms, and features like fault history and LED indicators, CoreSense
Diagnostics for Copeland compressors enable technicians to diagnose the past and recent state of the system,
allowing for quicker, more accurate diagnostics and less down time. The CoreSense Diagnostics is initially
available as standard with the 4- and 6-cylinder Stream compressors.
