Compressor diagnostic system
First Claim
1. A system comprising logic circuitry in communication with an intelligent device, said logic circuitry processing at least one of a status of a motor protector, a current drawn by a compressor of a refrigeration system, and a demand signal as function of time, at least one of said logic circuitry and said intelligent device diagnosing a specific fault cause of said compressor based on said processing and based on an average ON time of said compressor, said intelligent device outputting said diagnosis.

Abstract
A system is provided and may include logic circuitry in communication with an intelligent device. The logic circuitry may process a refrigeration system operating parameter as a function of time and at least one of the logic circuitry and the intelligent device may diagnose a refrigeration system status based on the processing. The intelligent device may output the diagnosis.
