Integrated protection mechanisms
When the PSSu E F PS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20 ms if the supply voltage is interrupted.
The module has the following protection mechanisms:
}
Cyclical output tests
}
Tests for shorts across the output
}
Test pulse signals are always buffered for 20 ms.
The module provides the following diagnostic data:
}
Start-up error
}
Configuration error
}
FS communication error
}
Bus termination error
}
Temperature error: too warm
}
Temperature: too hot
}
Output error
}
Test pulse error
}
Input error

Reaction times
Information on the reaction times of the inputs/outputs can be found in the "PSSuniversal"
System Description and the System Description "Automation system PSS 4000".

Dual-pole output
Functions for the FS outputs of a PSSu are defined in the PSSuniversal Configurator on the
PSS WIN-PRO system software:
}
Read access through the standard bus system (configured per module):
“R” configuration
}
Read/write access through the standard bus system (configured per output):
"&" configuration (local enable principle)
}
Optimisation of ST process image by combining adjacent bits of the same type.
“*” configuration
