Norcold N84X.3 User Manual

The Diagnostic Mode uses nine 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 45.

The N62X/N82X optical control display uses a single 7-
segment LED module to display diagnostic
information. Information made up of two letter or
numbers display in an alternating sequence. Fault
history information, "live" inputs, and outputs, are
presented using lighted LED segments. The
diagnostic LED segments, if present, displays after
the screen number turns off. Diagnostic LED
segments identification numbers. See Figure 46.
