A high level software watchdog has
detected a condition in which there was a
continuous 1 minute period of compressor
operation, with neither Evaporator water
flow nor a” contactor interrupt failure”
diagnostic active. 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.

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
(cmprsr 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.

The Starter module status reported back
that it is stopped when the MP thinks it
should be running and no Starter
diagnostic exist. This diagnostic will be
logged in the active buffer and then
automatically cleared. This diagnostic
could be caused by intermittent
communication problems from the Starter
to the MP, or due to mis-binding
