Description/Troubleshooting
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.
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.
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 RTAC 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 problem persists,
replace MP.
The "boot code" is the portion of the code that is resident in all MPs regardless of what application code (if any) is
loaded. Its main function is to run power up tests and provide a means for downloading application code via the MP's
serial connection. The Part numbers for the code are displayed in the lower left hand corner of the DynaView during
the early portion of the power up sequence and during special programming and converter modes. See below. For
the EasyView, the extension of the boot code part number is displayed for approximately 3 immediately following
power up.
// This is normal, but you should provide this information when contacting Technical Service about power up problems.
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.
There were RAM errors detected in RAM Test Pattern #1. // Recycle power, if the error persists, replace MP.
There were RAM errors detected in RAM Test Pattern #2. //Recycle power, if the error persists, replace MP.
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 can be caused by a near lightening
strike. Such events should be rare or isolated and if no damage results to the CH.530 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.
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 above
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.
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
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.
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.
MP has an invalid configuration based on the current software installed
No Main Processor Application is present – There are no RAM Test Errors.
// 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.
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.
