The module can detect the following errors:
(
1
) 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 switches off the
relay outputs.
 After the "too hot" message has been received, if the temperature
drops back below the "too warm" theshold value, the relay contacts
will close if the head module has set the status of the outputs to "1".
Further information on PSSu error messages is available in the online
help for the PSSuniversal Assistant system software.
