) There are two levels of overtemperature.
 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 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 system software.
Overload of the supply voltage for en-
coder Supply voltage for encoder overload-
ed or short-circuited Rectify overload or short circuit
Overvoltage error A system voltage or infeed is too high Stabilise the supply or change the
faulty supply voltage module
Undervoltage error A system voltage or infeed is too low Stabilise the supply or change the
faulty supply voltage module
Error in the overvoltage protection di-
odes Overvoltage protection diodes are de-
fective Change faulty supply voltage module
Timeout error on the output No data has been received for the out-
put from the module bus for longer
than 50 ms. Check ST communication or configu-
ration
Polarity error Polarity of the periphery supply Correct the polarity
Error in the periphery supply Lower voltage limit exceeded on the
periphery supply Ensure there is a sufficient supply
