A module error is displayed via the "Err" LED (see section entitled "Display elements"). It is
signalled to the head module and then entered in the

of the head module.
The module can detect the following errors:
Module error
Statement
Remedy

Ambient temperature too high:
Reset the module and stop the af-
fected I/O-Groups (SafetyBUS p)

Too warm:
If a module's temperature exceeds a threshold 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 threshold value, the module sends an error
message to the head module and triggers an I/O-Group stop.
