Abstract: A method for addressing a slave device in a network system comprising a master device and a plurality of slave devices. The slave devices have a common default address in an unaddressed state and the master device and the plurality of slave devices are connected in chain via a power line and a communication line, wherein each slave device is indexed by an index greater than or equal to 1, the slave device of index 1 being connected to the master device, wherein, to address the slave device of index k, k being equal to or greater than 2, the method first instructs the slave device of index k?1 to activate the power supply of the slave device of index k via the power line, and then, it sends, to the common default address on the communication line, a command to change the common default address of the slave device of index k to a unique address of index k. Therefore, at each iteration, there is only one unaddressed slave device in the network.

Abstract: An apparatus and method for selectively automatically resetting an electronic protection device. The electronic protection device may protect a motor load by disconnecting the load from a power source when the current drawn by the load exceeds a threshold, when the power source suffers from a phase imbalance or phase loss, or when another condition is detected. The electronic protection device discriminates between different types of fault conditions and determines whether to suppress an automatic reset function of the device. The electronic protection device includes a reset energy storage device for automatically resetting the electronic protection device following a trip event using energy from the reset energy storage device. In operation, the electronic protection device detects a fault condition not calling for an automatic reset, then discharges the reset energy storage device and trips the electronic protection device before the reset energy storage device recharges.
