Service Interface
AFD Operator Interface
Chiller information is tailored to operators, service
technicians, and owners. When operating a chiller, there is
specific information you need on a day-to-day basis—
setpoints, limits, alarm information, and reports.
When servicing a chiller, you need different information
and usually more of it—historic and active alarms,
configuration settings, and customizable control
algorithms, as well as operation settings.
By providing two different tools—one for daily operation
and one for periodic service—everyone has easy access to
pertinent and appropriate information.
Tracer AdaptiView Operator Interface
The Chiller's Tracer AdaptiView display is the Operator
interface for the Adjustable Frequency Drive (AFD). For the
operator's day-to-day operational information, Tracer®
AdaptiView™ displays data (English or SI units)
simultaneously on the 12-inch, color touch-sensitive
screen. Logically organized groups of information—chiller
modes of operation, active alarms, settings and reports
put information conveniently at your fingertips. The AFD
status can be viewed from the Tracer® AdaptiView™
MOTOR target area on the home page. Refer to the Tracer
AdaptiView Display for CenTraVac Chillers, Daily
Table 5.
The following Adaptive Frequency Drive (AFD) information is available from the Tracer AdaptiView display:

Tracer TU Service Tool (Laptop Computer)
Tracer® TU is software installed on a portable laptop
computer and used, by the service technician or advanced
operator, to interface with the UC800 controller on the
CenTraVac™ chiller. When you need more detailed
information about a Trane® chiller, connect your laptop
computer (with the Tracer® TU software installed) to the
UC800's "Service Tool" USB plug-in port (this port is
extended to exterior of the control panel cabinet for easy
access).
The Tracer® TU software provides access to that particular
machine's configuration settings, customizable limits,
status, and up to 60 active or historic alarms. A technician
can interact with an individual device or a group of devices
for advanced troubleshooting. For more information on
Tracer® TU, visit your local Trane Service company, or
Trane's website at www.Trane.com.
Use Tracer® TU when a factory or startup setting requires
field alterations. All adjustable AFD settings (see
Table 11, p.
45) are available via Tracer TU. All others are
set to defaults predetermined for this application as based
on laboratory testing.

Oil/refrigerant/(AFD water pump) manual control
Manual control allows the user to override the automatic signal
and manually drive the Compressor Control Signal from 0–100%.
The limits and safeties remain active. The compressor control
signal controls a calculated combination vanes position and drive
speed for leaving water control signal.
