Communication Diagnostics

Notes:
• The following communication loss diagnostics will not
occur unless that input or output is required to be
present by the particular configuration and installed
options for the chiller.
• Communication diagnostics (with the exception of
"Excessive Loss of Comm" are named by the
Functional Name of the input or output that is no
longer being heard from by the Main Processor. Many
LLIDs, such as the Quad Relay LLID, have more than

one functional output associated with it. A comm loss
with such a multiple function board, will generate
multiple diagnostics. Refer to the Chiller's wiring
diagrams to relate the occurrence of multiple
communication diagnostics back to the physical LLID
boards that they have been assigned to (bound).
• Communication loss diagnostics shall be timed based
on action (target status) and not annunciation on the
operator display.
