Diagnostic Screen

The diagnostic screen (shown following) is accessible by
either pressing the blinking ALARMS key or by pressing
the Diagnostic tab on the screen tab selection.
A hex code and a verbal description appears on the display
as shown typically above.This is the last active diagnostic.
Pressing the "Reset All Active Diagnostics" will reset all
active diagnostics regardless of type, machine or
refrigerant circuit. Compressor diagnostics, which hold off
only one compressor, are treated as circuit diagnostics,
consistent with the circuit to which they belong. One
circuit not operating will not shut the chiller down.Viewing
the "Compressor" screen will indicate whether a circuit is
not operating and for what reason.
A complete listing of diagnostics and codes is included in
the Diagnostic Section.
