Reported if state chart misalignment in stopped or inactive
state occurred while a compressor was seen to be
operating and this condition lasted for at least 1 minute
(cprsr operation due to Service Pumpdown or with
Contactor Interrupt Failure diagnostic is excluded). The
presence of this software error message suggests an
internal software problem has been detected. The events
that led up to this failure, if known, should be recorded and
transmitted to Trane Controls Engineering.

NonLatch All
The main processor has successfully come out of a reset
and built its application. A reset may have been due to a
power up, installing new software or configuration. This
diagnostic is immediately and automatically cleared and
thus can only be seen in the Historic Diagnostic List in
Tracer TU.

The system differential pressure was below 7.7 Psid (53
kPa) for 6 seconds after the 11 seconds ignore time relative
to cprsr/circuit start-up had expired. In a two compressor
circuit, the lower of the two suction pressure is used for
circuit DP.
