A Valid Configuration is

A valid configuration is present in the MP's nonvolatile memory. The configuration is a set of variables and settings that

Present

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

An unhandled interrupt has occurred while running the application code. This event will normally cause a safe shutdown of

InterruptRestart Timer:

the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart the

[3 sec countdown timer]

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

An Operating System error has occurred while running the application code. This event will normally cause a safe shutdown

ErrorRestart Timer:

of the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart

[3 sec countdown timer]

the application and allow a normal restart of chiller as appropriate.See Err 4.

 

 

Err6: Watch Dog Timer

A Watch Dog Timer Error has occurred while running the application code. This event will normally cause a safe shutdown of

ErrorRestart Timer:

the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart the

[3 sec countdown timer]

application allowing a normal restart of chiller as appropriate.

 

 

Err7: Unknown ErrorRestart

An unknown Error has occurred while running the application code. This event will normally cause a safe shutdown of the

Timer:

entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to restart the

[3 sec countdown timer]

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.

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.
