The leaving Evaporator water temp. fell below the leaving
water temp cutout setting for 30 degree-F seconds while
the Chiller is in the Stop mode, or in Auto mode with no
compressors running. Energize Evap Water pump Relay
until diagnostic auto resets, then return to normal evap
pump control. Automatic reset occurs when the temp rises
2°F (1.1°C) above the cutout setting for 30 minutes.

The Evaporator water temp. fell below the cutout setpoint
for 30 degree F Seconds while the compressor was
running. Automatic reset occurs when the temperature
rises 2 °F (1.1°C) above the cutout setting for 2 minutes.
This diagnostic shall not de-energize the Evaporator Water

The oil pressure was out of the acceptable pressure range
for 15 seconds, while the Delta Pressure was greater than
15 Psid.: Acceptable range is 0.50 or 0.60 > (PC-Po) / (PC-
PE) for the first 2.5 minutes of operation, and 0.40 or 0.50
> (PC-Po) / (PC-PE) thereafter. The higher ratios used if the
system DP is less than 23 psid

Chiller Warning 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.

A high level software watchdog has detected a condition in
which there was a continuous 5 minute period of
compressor operation, with neither chilled water flow nor
a” contactor interrupt failure” diagnostic active. The
occurrence of this software error message suggests an
internal software state chart misalignment has occurred.
The events that led up to this failure, if known, should be
recorded and transmitted to Trane Controls Engineering –
(SW rev 6 and higher)
