Abstract
An electronic trip unit having a number of trip unit settings includes: a first input member; a second input member; a multi-position selector configured to select one of plurality of positions corresponding to values of the trip unit settings; a plurality of indicators each corresponding to one of the plurality of trip unit settings; and a processor having a routine, wherein the routine of the processor is structured to, in response to actuation of the first input member, increment a ring counter value and selectively activate one of the indicators corresponding to the ring counter value; and wherein the routine of the processor is further structured to, in response to actuation of the second input member, set a value of the trip unit setting corresponding to the activated indicator based on the selected position of the multi-position selector.
