2.4 Manual Trip Test and Reset

Both outputs can be tripped manually by applying a logic high to the SETA and SETB inputs to evaluate the functionality of the outputs. On the evaluation board, there are two designated push buttons—S1 and S2—to trip OUTA and OUTB, respectively. The output LEDs for OUTA and OUTB, D3 (red) and D4 (green), will illuminate when the trip point is reached or if the output is forced by the trip test.
