Abstract
A system is provided and may include a compressor operable in a refrigeration circuit. A first sensor may detect high-side data indicative of an operating condition of a high-pressure side of the refrigeration circuit and a second sensor may detect low-side data indicative of an operating condition of a low-pressure side of the refrigeration circuit. Processing circuitry may receive the high-side data and the low-side data from the first and second sensors and may process the high-side data and low-side data to determine at least one of a low-side fault and a high-side fault. The processing circuitry may operate the compressor in a normal mode in the absence of a low-side fault and a high-side fault and may operate the compressor in a reduced-capacity mode or a shutdown mode based on a severity of the at least one of the low-side fault and the high-side fault.
