General information  
Warranty  
Training  
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  
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.  
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.

Overview  
TheTrane CH530 control system  
that runs the chiller consists of  
several elements:  
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.  
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).  
Note: It is imperative that the CH530  
ServiceTool (TechView) be used to  
facilitate the replacement of any  
LLID or reconfigure any chiller  
component.

Each chiller is equipped with the  
DynaView interface. DynaView has

The following diagnostic table  
contains all the diagnostics  
possible. Not all data is available  
unless tech view is connected.  
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).  
Code: Three digit hexadecimal code  
used on all past products to  
uniquely identify diagnostics.  
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.  
Diagnostic Name: Name of  
Diagnostic and its source. Note that  
this is the exact text used in the  
User Interface and/or ServiceTool  
displays.  
Reset Level: Defines the lowest level  
of manual diagnostic reset  
command which can clear the  
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

generated.  
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.

MP Application Memory CRC App software inside the MP failed its own checksum test. Possible causes: application software in the MP is not complete -  
Error  
software download to the MP was not completed successfully - or MP hardware problem. Note: User should attempt to  
reprogram the MP if this diagnostic occurs.  
App Present. Running

SelftestErr3: CRC Failure  
An application has been detected in Main Processor's nonvolatile memory and the boot code is proceeding to run a check on  
its entirety. A few seconds later, the boot code had completed but failed the (CRC) test.  
Connect a TechView Service Tool to the MP's serial port, provide chiller model number (configuration information) and  
download the configuration if prompted by TechView. Then proceed to download the most recent application or specific  
version as recommended by Technical Service. Note that this error display may also occur during the programming process, if  
the MP never had a valid application any time prior to the download. If the problem persists, replace the MP.

Diagnostics  
A Valid Configuration is  
Present  
A valid configuration is present in the MP's nonvolatile memory. The configuration is a set of variables and settings that  
define the physical makeup of this particular chiller. These include: number/airflow and type of fans, number/and size of  
compressors, special features, characteristics, and control options. Temporary display of this screen is part of the normal  
power up sequence.  
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  
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.See Err 4.  
Err6: Watch Dog Timer  
ErrorRestart Timer:  
[3 sec countdown timer]  
A Watch Dog Timer 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.  
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 A touch was detected during boot indicating the user wanted to stay in boot mode. This mode can be used to recover from a  
Press  
fatal software error in the application code. Cycle power on the MP to clear this error if it was unintentional.  
[3 sec countdown timer]  
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  
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 aTechView  
configuration.  
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.  
Table 8 - Chiller events/status descriptions  
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  
Maximum Capacity  
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.  
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.
