Abstract: H:\tld\Introvn\NRPortbl\DCC\TLD\8125054_ .docx-28/07/2015 -29 A compressor includes a shell, a compression mechanism, a motor, a data module, and a compressor controller. The data module includes a processor and a 5 memory. The compressor controller includes a processor and a memory. The data module receives sensed data, stores sensed data in the memory, and communicates sensed data to the compressor controller. The compressor controller controls a capacity of the compressor based on the sensed data and is operable to communicate with a system controller of a refrigeration system.

Abstract: A refrigeration system and method includes a refrigeration component and an electronics module preconfigured with a data set for the refrigeration component. The electronics module stores the data set including identification and configuration parameters of the refrigeration component. A refrigeration system controller that communicates with the electronics module to copy the data set and to regulate operation of the refrigeration component within the refrigeration system.

Abstract: A refrigeration/air conditioning system includes a compressor (10) having a motor protector (54) which stops the compressor's motor when it senses an out of specification condition, A diagnostic system (100) of the refrigeration/air conditioning system monitors the status of the motor protector (54). The diagnostic system (100) includes logic circuitry (104) that diagnoses the type of problem the compressor (10) or the system is having based upon the running times and status of the motor in conjunction with the times and status of the tripped motor protector (54). The diagnostic system (100) also includes either a discharge pressure sensor (330) or a condenser temperature sensor (332), an ambient air sensor (334) and a voltage sensor (404). The sensors provide information to the diagnostic system (100) which enables it to determine where a system fault has occurred.

Abstract: A compressor is provided and may include a shell, a compression mechanism, a motor, and a diagnostic system that determines a system condition. The diagnostic system may include a processor and a memory and may predict a severity level of the system condition based on at least one of a sequence of historical-fault events and a combination of the types of the historical-fault events.
