Abstract
A system and method for diagnosing and protecting a compressor includes a sensor, logic circuitry, a motor protector and an intelligent device. The logic circuitry is associated with the sensor and the motor protector and operable to determine a trip frequency of the motor protector and identify a specific fault cause. The intelligent device communicates with the logic circuitry and indicates the fault cause.
