Integrated protection mechanisms
When the PSSu E F PS1(-T) is used to supply the system, the module supply is buffered
for 20 ms if the supply voltage is interrupted.
The module provides the following diagnostic data:
}
Start-up error
}
Configuration error
}
ST communication error
}
Bus termination error
}
Output overload
}
Temperature error: too warm
}
Temperature error: too hot
