Abstract: A motor starter control is disclosed in which an ambient temperature sensor is positioned to sense ambient temperature and pole temperature sensors are used to sense each pole temperature in a motor starter. A microprocessor is connected to periodically receive the temperature signals and monitor change in operating temperature of a motor starter system. The microprocessor models cool down characteristics of the motor starter system and compares currently acquired ambient and pole temperature signals to the modeled cool down characteristics and determines whether the motor starter system is cooled to a safe start temperature. The control ensures that a maximum number of starts per hour is not exceeded and prevents attempted starts that not only waste energy, but further prolong time to a successful start.

Abstract: A motor starter temperature protection control in which an ambient temperature sensor is positioned on an inside cover of the motor starter to sense ambient temperature across the power poles and heat sinks and provide an ambient temperature signal indicative of the ambient temperature in the motor starter enclosure. A power pole temperature sensor is positioned in thermal communication with each power pole and produce pole temperature signals indicative of the temperature of each power pole. A microprocessor is connected to each of the temperature sensors and receives the ambient temperature and the pole temperature signals to control the motor starter operation based on the temperature inputs. The microprocessor is programmed to periodically monitor the ambient and power pole temperature signals and compare these signals against a fan-on limit, and if the signals exceed the fan-on limit, the control turns on the internal fans of the motor starter. The control continues to monitor the ambient and power pole temperatures and if either should exceed a maximum temperature limit, the motor starter is placed in a motor shutdown mode, unless an optional temperature override has been set. Upon motor shutdown, the control continues to monitor temperatures and track how long it takes for the motor starter to cool down, and if it takes too long to cool down, a maintenance flag is set to indicate that cleaning or preventive maintenance is required.

Abstract: A flexible electrical connector is attached to a movable contact finger and a stationary termianl by placing the components in a work chamber and positioning a first end of the flexible connector against an attachment surface of the contact finger, preferably in a perpendicular orientation. After evacuating the work chamber, the output of an electron gun is directed toward a joint formed between the flexible connector and the contact finger. The electron beam forms a weld zone which fuses the the flexible connector with the contact finger without degrading the flexibility of the connector or the mechanical strength of the contact finger. A second end of the flexible connector is positioned against an attachment surface of the stationary terminal, such as in a parallel orientation, and attached in a similar manner.

Abstract: An automatic electric load transfer switch incorporates an over-the-center spring mechanism to operate switch contacts. The spring mechanism has a first position at which the electric load is connected to one electricity source and a second position at which the load is connected to another electricity source. The spring mechanism is driven by a solenoid activated cam shaft. An apparatus is provided for halting the movement of the spring mechanism at a position intermediate the first and second positions at which the load is not connected to either electricity source. The halting apparatus is releasable so that the spring mechanism can continue its movement between the first and second positions.
