Tracer™ TU
The operator interface allows for daily operational tasks and setpoint changes. However, to adequately service
chillers Tracer™ TU service tool is required. (Non-Trane personnel, contact your local Trane office for software
purchase information.) Tracer TU adds a level of sophistication that improves service technician effectiveness and
minimizes chiller downtime. This portable PC-based service-tool software supports service and maintenance tasks,
and is required for software upgrades, configuration changes and major service tasks.
Tracer TU serves as a common interface to all Trane® chillers, and will customize itself based on the properties of
the chiller with which it is communicating. Thus, the service technician learns only one service interface.
The panel bus is easy to troubleshoot using LED sensor verification. Only the defective device is replaced. Tracer TU
can communicate with individual devices or groups of devices.
All chiller status, machine configuration settings, customizable limits, and up to 100 active or historic diagnostics are
displayed through the service-tool software interface.
LEDs and their respective Tracer TU indicators visually confirm the availability of each connected sensor, relay,
and actuator.
Tracer TU is designed to run on a customer’s laptop, connected to the Tracer control panel with a USB cable.
Your laptop must meet the following hardware and software requirements:
• 1 GB RAM (minimum)
• 1024 x 768 screen resolution
• CD-ROM drive
• Ethernet 10/100 LAN card
• An available USB 2.0 port
• Microsoft® Windows 7
• Enterprise or Professional operating system (32-bit or 64-bit)
• Microsoft .NET Framework 4.0 or later
Note:
Tracer TU is designed and validated for this minimum laptop configuration. Any variation from this configuration
may have different results. Therefore, support for Tracer TU is limited to only those laptops with the configuration
previously specified.
For more information, see TTU-SVN01A-EN Tracer TU Getting Started Guide
Diagnostic Name and Source: Name of Diagnostic and its source. Note that this is the exact text used in the
User Interface and/or Service Tool displays.
Affects Target: Defines the “target” or what is affected by the diagnostic.
Usually either the entire Chiller, or a particular Circuit or Compressor is affected by the diagnostic (the same one as
the source), but in special cases functions are modified or disabled by the diagnostic. None implies that there is no
direct affect to the chiller, sub components or functional operation.
Design Note: Tracer™ TU does not support the display of certain targets on its Diagnostics pages although the
functionality implied by this table is supported. Targets such as Evap Pump, Ice Mode, Chilled Water Reset, External
Setpoints etc. – are displayed as simply “Chiller” even though they do not imply a chiller shutdown – only a
compromise of the specific feature.
Severity: Defines the severity of the above effect. Immediate means immediate shutdown of the affected portion,
Normal means normal or friendly shutdown of the affected portion, Special Action means a special action or mode
of operation (limp along) is invoked, but without shutdown, and Info means an Informational Note or Warning is
generated. Design Note: Tracer TU does not support display of “Special Action”, on its Diagnostics pages, so that if
a diagnostic has a special action defined in the table below, it will be displayed only as “Informational Warning” as
long as no circuit or chiller shutdown results. If there is a shutdown and special action defined in the table, then the
Tracer TU Diagnostics Page display will indicate the shutdown type only.
Persistence: Defines whether or not the diagnostic and its effects are to be manually reset (Latched), or can be either
manually or automatically reset when and if the condition returns to normal (Nonlatched).
Active Modes [Inactive Modes]: States the modes or periods of operation that the diagnostic is active in and, as
necessary, those modes or periods that it is specifically “not active” in as an exception to the active modes. The
inactive modes are enclosed in brackets, [ ]. Note that the modes used in this column are internal and not generally
annunciated to any of the formal mode displays.
