) There are two levels of overtemperature.
 Too warm:
If a module's temperature exceeds a theshold value, the module
sends a warning to the head module. If the temperature drops back
below the threshold value, the module sends an all-clear.
 Too hot:
If a module's temperature exceeds a further theshold value, the mod-
ule sends an error message to the head module and triggers an
I/O-Group stop.
Further information on PSSu error messages is available in the online
help for the PSS WIN-PRO system software.
