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

Diagnostics
CG-SVU02B-E424
The following diagnostic table
contains all the diagnostics
possible. Not all data is available
unless tech view is connected.
Code: Three digit hexadecimal code
used on all past products to
uniquely identify diagnostics.
Diagnostic Name: Name of
Diagnostic and its source. Note that
this is the exact text used in the
User Interface and/or Service Tool
displays.
Severity: Defines the severity of the
above effect. Immediate means
immediate shutdown of the effected
portion, Normal means normal or
friendly shutdown of the effected
portion, Special Mode means a
special mode of operation (limp
along) is invoked, but without
shutdown, and Info means an
Informational Note or Warning is
generated.
Persistence: Defines whether or not
the diagnostic and its effects are to
be manually reset (Latched), or can
be either manually or automatically
reset (Nonlatched).
Criteria: Quantitatively defines the
criteria used in generating the
diagnostic and, if nonlatching, the
criteria for auto reset. If more
explanation is necessary a hot link
to the Functional Specification is
used.
Reset Level: Defines the lowest level
of manual diagnostic reset
command which can clear the
diagnostic. The manual diagnostic
reset levels in order of priority are:
Local and Remote. A diagnostic that
has a reset level of Local, can only
be reset by a local diagnostic reset
command, but not by the lower
priority remote Reset command
whereas a diagnostic listed as
Remote reset can be reset by either.

Err4: UnHandled
InterruptRestart Timer:
[3 sec countdown timer]
An unhandled interrupt has occurred while running the application code. This event will normally cause a safe shutdown of
the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart the
application and allow a normal restart of chiller as appropriate. This condition might occur due to a severe electro-magnetic
transient such as a near lightening strike. Such events should be rare or isolated and if no damage results to the CH530
control system, the Chiller will experience a shutdown and restart. If this occurs more persistently it may be due to an
MP hardware problem. Try replacing the MP. If replacement of the MP proves ineffective, the problem may be a result of
extremely high radiated or conducted EMI. Contact Technical Service.If this screen occurs immediately after a software
download, attempt to reload both the configuration and the application. Failing this, contact Technical Service.
Err5: Operating System
ErrorRestart Timer:
[3 sec countdown timer]
An Operating System error has occurred while running the application code. This event will normally cause a safe shutdown

application allowing a normal restart of chiller as appropriate.
Err7: Unknown ErrorRestart
Timer:
[3 sec countdown timer]
An unknown Error has occurred while running the application code. This event will normally cause a safe shutdown of the
entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart the
application allowing a normal restart of chiller as appropriate
Err8: Held in Boot by User Key
Press
[3 sec countdown timer]
A touch was detected during boot indicating the user wanted to stay in boot mode. This mode can be used to recover from a
fatal software error in the application code. Cycle power on the MP to clear this error if it was unintentional.
Converter Mode A command was received from the Service Tool (Tech View) to stop the running application and run in the "converter mode".
In this mode the MP acts as a simple gateway and allows the TechView service computer to talk to all the LLIDS on the
IPC3 bus.
Programming Mode A command was received by the MP from the Tech View Service Tool and the MP is in the process of first erasing and then
writing the program code to its internal Flash (nonvolatile) Memory. Note that if the MP never had a prior application already
in memory, the error code "Err3"will be displayed instead of this, during the programming download process.
Design Note: In general, all failures/comm loss due to CH530 components should have a latching diagnostic and effect. All customer inputs failures (out of range, etc) are
generally nonlatching.
Diagnostics
CG-SVU02B-E434
Programmable Relays
(Alarms and Status)
CH530 provides a flexible alarm or
chiller status indication to a remote
location through a hard wired
interface to a dry contact closure.
Four relays are available for this
function, and they are provided
(generally with a Quad Relay Output
LLID) as part of the Alarm Relay
Output Option.
The events/states that can be
assigned to the programmable
relays are listed in the following
table and through a TechView
configuration.
Event/state Description
Alarm - Latching This output is true whenever there is any active diagnostic that requires a manual reset to clear, that affects the chiller, the
circuit, or any of the compressors on a circuit. This classification does not include informational diagnostics.
Alarm - Auto reset This output is true whenever there is any active diagnostic that could automatically clear that affects the chiller, the circuit or
any of the compressors on a circuit. This classification does not include informational diagnostics. If all of the auto resetting
diagnostics were to clear, this output would return to a false condition.
Alarm This output is true whenever there is any diagnostic affecting any component, whether latching or automatically clearing. This
classification does not include informational diagnostics.
Warning This output is true whenever there is any informational diagnostic affecting any component, whether latching or automatically
clearing.
Chiller Limit Mode This output is true whenever the chiller has been running in one of the Unloading types of limit modes (Condenser,
Evaporator, Current Limit or Phase Imbalance Limit) continuously for the last 20 minutes. A given limit or overlapping of
different limits must be in effect continuously for 20 minutes prior to the output becoming true. It will become false, if no
Unload limits are present for 1 minute. The filter prevents short duration or transient repetitive limits from indicating. The
chiller is considered to be in a limit mode for the purposes of front panel display and annunciation, on if it is fully inhibiting
loading by virtue of being in either the "hold" or "forced unload" regions of the limit control, excluding the "limited loading
region". In previous designs, the "limit load" region of the limit control was included in the criteria for the limit mode call out
on the front panel and annunciation outputs.
Compressor Running The output is true whenever any compressors are started or running on the chiller and false when no compressors are either
starting or running on the chiller. This status may or may not reflect the true status of the compressor in Service Pumpdown
if such a mode exists for a particular chiller.
Maximum Capacity The output is true whenever the chiller has reached maximum capacity continuously for the Max Capacity Relay debounce
time. The output is false when the chiller does not have all its available compressors running continuously for the debounce
time.
Default setting Event/Status
