Abstract:
A motor overload coil control comprising:a plurality of inputs and outputs (I/Os) to and from the motor overload coil control having j inputs and k outputs, including at least one reset input, a current sense input, a full load amp (FLA) input, a coil control input, a coil control output, and a status output;a microcontroller having n input/output (I/O) lines, where n<(j+k);a motor overload circuit connecting the j inputs and k outputs to the microcontroller in a manner to prioritize and consolidate the plurality of I/Os into x I/Os such that n<x<(j+k), thereby reducing the plurality of I/Os but where a plurality of I/Os connected to the microcontroller still exceed the n I/O lines of the microcontroller; andwherein the microcontroller is programmed to use at least two of the n I/O lines to function as both an input and an output.
