DynaView Display Message	Description
	Troubleshooting
Boot Software Part Numbers:	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
LS Flash	main function is to run power up tests and provide a means for downloading application code via the MP's serial connection.
--> 6200-0318-XX	The Part numbers for the code are displayed in the lower left-hand corner of the DynaView during the early portion of the
MS Flash	power up sequence and during special programming and converter modes. See below.

Err2: RAM Pattern 1 Failure	There were RAM errors detected in RAM Test Pattern #1. Recycle power, if the error persists, replace MP.
Err2: RAM Pattern 2 Failure	There were RAM errors detected in RAM Test Pattern #2. Recycle power, if the error persists, replace MP.
Err2:	There were RAM errors detected in RAM Address Test #1. Recycle power, if error persists, replace MP.
RAM Addr Test #1 Failure
Err2:	There were RAM errors detected in RAM Address Test #2. Recycle power, if the error persists, replace MP.

	proceed to download the most recent application or specific version as recommended by Technical Service.
MP: Invalid Configuration	MP has an invalid configuration based on the current software installed
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.

	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.
