US Classification:

361 23

Abstract:

A motor is electrically coupled to a power source through a motor starter. The motor is selectively operated by a relay to connect and disconnect the power source to the motor.

Abstract:

A motor is electrically coupled to a power source through a motor starter. The motor starter is selectively operated by a relay to connect and disconnect the power source to the motor. A counter is set whenever a select motor temperature condition exceeds a predetermined level to provide an indication of the number of motor starts. The relay is operated to cause the motor starter to disconnect the power source from the motor whenever the motor fails to run continuously during a given time period following a predetermined number of starts.
