(

) 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
