Diagnostic occurs when accumulated circuit operating
hours since last initialized exceeds 2000 hours.
Diagnostic can be manually cleared but will reoccur
every month (720 hours on real time clock) as long as

(After RTUD release in Fall of 09:) Diagnostic occurs only
when "service messages" are enabled and when Oil
Filter Life remaining falls below 5 %. Diagnostic can be
manually cleared but will reoccur every month real time
(720 hours on real time clock) as long as the oil filter life
remaining does not rise above 20% (through normal
calculations or reinitializing) (Prior to RTUD Release in
Fall of 09): Diagnostic occurs only when "service
messages" are enabled and when average oil pressure
drop exceeds 18%. Diagnostic can be manually cleared
but will reoccur every month (720 hours on real time
clock) as long as average pressure drop does not fall
below 16%.

NonLatch
All The neuron software in the LCI-C module does not
match the chiller type. Download the proper software
into the LCI-C neuron. To do this, use the Rover service
tool, or a LonTalk® tool capable of downloading
software to a Neuron 3150®.

Immediate Latch
All
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.
