Warranty
Warranty is based on the general
terms and conditions of the
manufacturer. The warranty is void
if the equipment is repaired or
modified without the written
approval of the manufacturer, if the
operating limits are exceeded or if
the control system or the electrical
wiring is modified. Damage due to
misuse, lack of maintenance or
failure to comply with the
manufacturer's instructions or
recommendations is not covered by
the warranty obligation. If the user
does not conform to the rules of
this manual, it may entail
cancellation of warranty and
liabilities by the manufacturer.
Maintenance contract
It is strongly recommended that you
sign a maintenance contract with
your local Service Agency. This
contract provides regular
maintenance of your installation by
a specialist in our equipment.
Regular maintenance ensures that
any malfunction is detected and
corrected in good time and
minimizes the possibility that
serious damage will occur. Finally,
regular maintenance ensures the
maximum operating life of your
equipment. We would remind you
that failure to respect these
installation and maintenance
instructions may result in
immediate cancellation of the
warranty.
Training
To assist you in obtaining the best
use of it and maintaining it in
perfect operating condition over a
long period of time, the
manufacturer has at your disposal a
refrigeration and air conditioning
service school. The principal aim of
this is to give operators and
technicians a better knowledge of
the equipment they are using, or
that is under their charge. Emphasis
is particularly given to the
importance of periodic checks on
the unit operating parameters as
well as on preventive maintenance,
which reduces the cost of owning
the unit by avoiding serious and
costly breakdown.

Overview
5CG-SVU02B-E4
The Trane CH530 control system
that runs the chiller consists of
several elements:
• The main processor collects
data, status, and diagnostic
information and communicates
commands to the
LLID (for Low
Level Intelligent Device)
bus. The
main processor has an integral
display (DynaView).
•
LLID bus
. The main processor
communicates to each input and
output device (e.g. temperature
and pressure sensors, low
voltage binary inputs, analog
input/output) all connected to a
four-wire bus, rather than the
conventional control architecture
of signal wires for each device.
• The
communication interface
to
a building automation system
(BAS).
•A
service tool
to provide all
service/maintenance capabilities.
Main processor and service tool
(TechView) software is
downloadable from
www.Trane.com
. The process is
discussed later in this section
under TechView Interface.
DynaView provides bus
management. It has the task of
restarting the link, or filling in for
what it sees as "missing" devices
when normal communications
has been degraded. Use of
TechView may be required.
The CH530 uses the IPC3 protocol
based on RS485 signal technology
and communicating at 19.2 Kbaud
to allow 3 rounds of data per
second on a 64-device network.
Most diagnostics are handled by the
DynaView. If a temperature or
pressure is reported out of range by
a LLID, the DynaView processes this
information and calls out the
diagnostic. The individual LLIDs are
not responsible for any diagnostic
functions.
Note:
It is imperative that the CH530
Service Tool (TechView) be used to
facilitate the replacement of any
LLID or reconfigure any chiller
component
.
Controls Interface
DynaView (picture on cover)
Each chiller is equipped with the
DynaView interface. DynaView has
the capability to display additional
information to the advanced
operator including the ability to
adjust settings. Multiple screens are
available and text is presented in
multiple languages as factoryordered or can be easily
downloaded online.
TechView
TechView can be connected to the
DynaView module and provides
further data, adjustment
capabilities, diagnostics
information, downloadable
software, and downloadable
languages.
DynaView Interface
CG-SVU02B-E46
The display on DynaView is a
1/4 VGA display with a resistive
touch screen and an LED backlight.
The display area is approximately
4 inches wide by 3 inches high
(102mm x 60mm).
CAUTION!
Equipment Damage! Putting
excessive pressure on the touch
screen could cause damage. It takes
less than 7 kg of force to break the
screen.
In this touch screen application, key
functions are determined
completely by software and change
depending upon the subject matter
currently being displayed. The basic
touch screen functions are outlined
below.
Radio Buttons
Radio buttons show 1 menu choice
among 2 or more alternatives, all
visible. The possible selections are
each associated with a button. The
selected button is darkened,
presented in reverse video to
indicate it is the selected choice. The
full range of possible choices as
well as the current choice is always
in view.
Spin Value Buttons
Spin values are used to allow a
variable setpoint to be changed,
such as leaving water setpoint. The
value increases or decreases by
touching the (+) or (-) arrows.
Action Buttons
Action buttons appear temporarily
and provide the user with a choice
such as Enter or Cancel.
File Folder Tabs
File folder tabs are used to select a
screen of data. The tabs are in 1 row
across the top of the display. The
user selects a screen of information
by touching the appropriate tab.
Display Screens
The main body of the screen is used
for description text, data, setpoints,
or keys (touch sensitive areas). The
Chiller Mode is displayed here.
A double arrow pointing to the right
indicates more information is
available about the specific item on
that same line. Pressing it will bring
you to a sub-screen that will present
the information or allow changes to
settings.

The bottom of the screen (7) is
present in all screens and contains
the following functions. The contrast
(8,9) may require re-adjustment at
ambient temperatures significantly
different from those present at last
adjustment. The other functions are
critical to machine operation. The
AUTO and STOP keys are used to
enable or disable the chiller. The key
selected is in black (reverse video).
The chiller will stop when the STOP
key is touched and after completing
the Run Unload mode.
Touching the AUTO key will enable
the chiller if no diagnostic is
present. (A separate action must be
taken to clear active diagnostics.)
The AUTO and STOP keys take
precedence over the Enter and
Cancel keys. (While a setting is
being changed, AUTO and STOP
keys are recognized even if Enter or
Cancel has not been pressed.) The
ALARMS button appears only when
an alarm is present, and blinks (by
alternating between normal and
reverse video) to draw attention to a
diagnostic condition. Pressing the
ALARMS button takes you to the
corresponding tab for additional
information.
Keypad/Display Lockout
Feature
Note:
The DynaView display and
Touch Screen Lock screen is shown
above. This screen is used if the
Display and touch screen and lock
feature is enabled. Thirty minutes
after the last keystroke, this screen
is displayed and the Display and
Touch Screen is locked out until the
sequence "159 <ENTER>" is
pressed.
Until the proper password
is entered, there will be no access
to the DynaView screens including
all reports, setpoints, and
Auto/Stop/Alarms/Interlocks. The
password "159" can not be changed
from either DynaView or TechView.
For setting changes, use the
password "314 <ENTER>".
