Where:

F = overload fault bits – 1 = fault present; 0 = no fault
Ox = Output Data (O0 corresponds to output 0, O1 corresponds to output 1, and so on)
FR = fault reset bit – 1 = reset output; 0 = no change.

Using the Fault Reset Button When you press the manual reset button:
1. The fault indicator for the faulted output turns off for about 1.2 s (the faulted output will not attempt to turn on during this delay)
2. After the 1.2 s delay, the faulted output attempts to turn on
3. If the external condition causing the fault is corrected, the output remains on, the fault indicator is off, and the status indicator is on

(1)

The unused lower byte in read word 1 floats during operation. Do not use this byte for fault status.
