Where
O = Output – O0 corresponds to output 0, O1 corresponds to output 1, and so on.
F = Overload fault bit – 1 = fault present; 0 = no fault
FR = Fault reset bit – 1 = reset output; 0 = no change
Note: The unused lower byte in read word 1 floats during operation. Do not use this byte for fault status. See
