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-SVU02E-GB
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.
Te c h V i e w
TechView can be connected to the DynaView module and provides further data, adjustment capabilities, diagnostics information, downloadable software, and downloadable languages.

DynaView Interface
CG-SVU02E-GB6
Power Up
On power-up, Dynaview will progress through 3 screens.
The first screen (Figure 1) will display for 3-10 seconds. This screen will give the status of the Application software, the Boot Software P/N, selftest results and the application part number. The contrast is adjustable from this screen. The message "Selftest passed" may be replaced with "Err2: RAM Error" or 3Err3: CRC Failure"
Figure 1

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>".

Active Chilled Water Subscreen
The active chilled water setpoint is the setpoint which the unit is currently controlling. It is the result of arbitration between the front panel, BAS, external, and auxiliary setpoints (auxiliary not shown in the following figure), which in cases may be subjected to a form of chilled water reset.
Page 12
DynaView Interface
CG-SVU02E-GB12
The chilled water reset status area in the most right column will display one of the following messages
• Return
• Constant Return
• Outdoor
• Disabled
The left column text "Front Panel", "BAS", "External", "Auxiliary", "Chilled Water Reset", and "Active Chilled Water Setpoint" will always be present regardless of installation or enabling those optional items. In the second column, "-----" will be shown if that option is Not Installed. Otherwise the current setpoint from that source will be shown.
Setpoints that are adjustable from the DynaView (Front Panel chilled water setpoint, Auxiliary chilled water setpoint) will provide navigation to their respective setpoint change screen via a double-arrow to the right of the setpoint source text. The setpoint change screen will look identical to the one provided in the Chiller Setpoints screen. The "Back" button on the setpoint change screen provides navigation back to the setpoint arbitration screen.
The "Back" button on the setpoint arbitration screen provides navigation back to the chiller screen.
Other Active Setpoints
The Active Hot Water Setpoint will behave the same way as the Active Chilled Water Setpoint, with the exception that Hot Water does not have an Auxiliary source. Front Panel Hot Water Setpoint will provide navigation to its setpoint change screen.
The Active Demand Limit Setpoint will behave the same way as the Active Chilled Water Setpoint, except that its units are % and there is an Ice Building source in place of the Auxiliary source. Front Panel Demand Limit Setpoint will provide navigation to its setpoint change screen.
The Active Ice Termination Setpoint will behave the same way as the Active Chilled Water Setpoint, with the exception that Ice Termination does not have an external or auxiliary source.

Auto, Stop/Panic Stop
The AUTO and STOP keys are radio buttons within the persistent key display area. The selected key will be black.
The chiller will stop when the STOP key is touched, entering the Run Unload mode. An informational screen will be displayed for 5 seconds indicating that a second depression of an "Immediate Stop" key during this time period will result in an immediate/panic stop. Pressing the "Immediate Stop" key while the panic stop screen is displayed, will cause the unit to stop immediately, skipping the run unload period.
Touching the Auto key will arm the chiller for active cooling if no diagnostic is present. As in UPC2, 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.
When an active diagnostic is present, an ALARMS key will be added to the persistent display area. This key is used to alert the operator that a diagnostic exists, or to provide navigation to a diagnostic display screen.

Diagnostics Screen
The diagnostic screen is accessible by depressing the Alarms enunciator A scrollable list of the last (up to 10) active diagnostics will be presented.
Performing a Reset All Active Diagnostics will reset all active diagnostics regardless of type, machine or refrigerant circuit. Compressor diagnostics, which hold off only one compressor, will be treated as circuit diagnostics, consistent with the circuit to which they belong.
The scrollable list will be sorted by time of occurrence. If a diagnostic of severity = warning is present, the "Alarms" key will be present but not flashing. If a diagnostic of severity = shutdown (normal or immediate) is present, the "Alarm" key will display that is flashing. If no diagnostics exist, the "Alarm" key will not be present.
The "Operating Mode At Last Diagnostic" text above the most recent diagnostic will display a sub­screen listing the operating mode and submodes at the time of the last diagnostic.

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.

Table 5 - Communication Diagnostics
Notes:
1. The following communication loss diagnostics will not occur unless that input or output is required to be present by the particular configuration and installed options for the chiller.
2. Communication diagnostics (with the exception of "Excessive Loss of Comm" are named by the Functional Name of the input or output that is no longer being heard from by the Main Processor.
Many LLIDs, such as the Quad Relay LLID, have more than one functional output associated with it. A comm loss with such a multiple function board will generate multiple diagnostics. Refer to the Chiller's wiring diagrams to relate the occurrence of multiple communication diagnostics back to the physical llid boards that they have been assigned to (bound).

App software inside the MP failed its own checksum test. Possible causes: application software in the MP is not complete ­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 Selftest.Selftest Passed
An application has been detected in the Main Processor's nonvolatile memory and the boot code is proceeding to run a check on its entirety. 8 seconds later, the boot code had completed and passed the (CRC) test. Temporary display of this screen is part of the normal power up sequence.
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.

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 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.

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
Output relay 1 Compressor running
Output relay 2 Latching alarm
Output relay 3 Chiller limit mode
Output relay 4 Warnings
