NonLatch All
For systems with no evaporator pump
or a single evaporator pump, a normal
shutdown shall be performed. For
multiple pump systems, detection of a
pump fault will generally cause pump
control to switch to the redundant
pump. See “Chilled Water Pump
Control - Field Supplied Dual Pumps,”
p. 82 for more details.

Immediate Latch All
A software monitor has detected a
condition in which there was a
continuous 1 minute period of
compressor operation, with no
Evaporator water flow. 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.

Immediate Latch All
A software monitor has detected a
condition in which there was a
continuous 1 minute period of
compressor operation, with a
misaligned state machine.
Reported if state chart misalignment
occurred inferred form the Capacity
Control, Circuit, or Compressor State
Machines being in Stopped state or
Inactive state while a compressor was
operating and this condition existed for
at least 1 minute. 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.
