1. The following sensor failure diagnostics will
not occur unless that input or output is
required to be present by the particular
configuration and installed options for the
chiller.
2. Sensor diagnostics are named by the
Functional Name of the input or output that
is no longer sending a valid value to the
Main Processor, indicating a sensor failure.
Some LLIDs may have more than one
functional output associated with it. Refer to
the unit’s wiring diagrams to relate the
occurrence of such sensor failure
diagnostics back to the physical LLID boards
that they have been assigned to (bound).
