Cprsr Warning
NonLatch All
When restart inhibit warning is enabled, the warning exists
when unit has been inhibited from starting and is cleared
when a start of a compressor is possible (Start-to-Start
Timer expires).
Remote
Software Error
1001: Call Trane
Service
Chiller 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.
Local
Software Error
1002: Call Trane
Service
Chiller Immediate Latch All
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.
Local
Software Error
1003: Call Trane
Service
Chiller Immediate Latch All
Reported if state chart misalignment occurred inferred from
the Capacity Control, Circuit, or Compressor State
Machines remaining in the Stopping state for more than 3
minutes. 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
Starter Panel High Limit Thermostat (170°F) trip was
detected. Compressor 1A is shutdown and inoperative until
the thermostat resets. Note: Other diagnostics that may
occur as an expected consequence of the Panel High Temp
Limit trip will be suppressed from annunciation. These
include Momentary Power Loss, Phase Loss, Power Loss,
and Transition Complete Input for Compressor 1A.
