Diagnostic Mode

The Diagnostic Mode uses ten diagnostic channels,
commonly known as "screens", to display "live"
inputs, outputs, and fault history. Each screen is
identified by a number, which shows in the optical
control assembly display. See Figure 47.
The N64X/N84X 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 identification numbers. See
Figure 48.
