Err5: Operating System
Error
Restart Timer:
[30 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 above
Err6: Watch Dog Timer Error
Restart Timer:
[30 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 Error
Restart Timer:
[30 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
The boot detected a key press in the center of the DynaView or both the + and - keys pressed on an EasyView while the
MP was in the boot code. Upon seeing this message the user can use Techview to connect to the MP to perform a
software download or another service tool function.
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.
