Diagnostic Mode
The Diagnostic Mode uses ten diagnostic channels,
commonly known as "screens", to display "live" inputs,
outputs, and fault history. Each screen is identifi ed by
a number, which shows in the optical control assembly
display. See Figure 8.
The NX64 / NX84, NXA64 / NXA84 optical control
display uses a dual 7-segment LED module to display
the screen number and diagnostic information.
Information made up of four letters or digits displays
in an alternating sequence. Fault history, "live" inputs,
and outputs is presented using LED segments. The
diagnostic LED segments, if present, display to the
right of the screen number. Diagnostic LED segments
identifi cation numbers. See Fig. 9.
