CTV-PRC001-GB
Welded steel two pass water boxes are
bolted to the tube sheets. Water
connections are steel pipe stubs
grooved for Victaulic couplings; flanged
connections are optionally available.
Maximum waterside working pressure
of 10.5 bars (150 psi) is standard. The
waterside is hydrostatically tested at 1.5
times maximum working pressure.
Unit Control Panel
The Tracer
™
CH.530 is a
microprocessor-based chiller controller
that provides complete stand alone
system control for water-cooled
centrifugals. It is a factory-mounted
packaged and tested on the CVGF unit.
All controls necessary for the safe and
reliable operation of the chiller are
provided including oil management,
interface to the starter, and three phase
motor overload protection. It also
includes comprehensive status and
diagnostic monitoring controls. A
control power transformer included in
the starter panel powers the control
system.
The microprocessor controller is
compatible with reduced voltage or full
voltage electro-mechanical starters,
and solid state starter. Starter for
Europe with the CE mark is available.
The microcomputer control system
processes the leaving evaporator fluid
temperature sensor signal to satisfy the
system requirements across the entire
load range.
The controller will load and unload the
chiller via control of the stepper- motor/
actuator which drives the inlet guide
vanes open and closed. The load range
can be limited either by a control limit
function such as motor current, low
evaporator temperature or high
condenser pressure limit or by an inlet
guide vane limit (whichever comes
first). It will also control the evaporator
and condenser pumps to insure proper
chiller operation.
Status and 10 active diagnostics are
communicated to the operator via
display with a tabbed navigation
system. Setpoints are entered through
the touch-sensitive screen. Countdown
timer displays remaining time(s) during
wait states and time out periods.
Nonvolatile memory saves unit set-up
information during power loss without
the need for batteries. Password
protection is provided to secure the
operator interface. PC-based service
tool software displays the last 60 active
or 60 historic diagnostics, indicating the
time, date of occurrence, and system
parameters at the time of the diagnostic.
The service tool provides advanced
troubleshooting and access to
sophisticated configuration settings not
needed during operation of the chiller.
Any PC that meets the installation
requirements may be loaded with the
service tool software via download
from www.trane.com.
Unit mounted display is capable of
displaying chiller parameters in IP or SI
units, and language in English and any
2 downloadable and/or locally
translated languages.
