4.2.2
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:
}
1 monitored relay contact per output
}
Protective separation between both relay contacts (see Technical details)
}
Protective separation between both relay contacts and the periphery supply as well as
the module supply, in accordance with DIN VDE 0110 overvoltage category 2 in a protec-
ted industrial network
}
Temperature monitoring
The module provides the following diagnostic data:
}
Start-up error
}
Configuration error
}
FS communication error
}
Bus termination error
}
Temperature error: Too warm
}
Temperature error: Too hot
}
Relay control error
}
Relay error

Configuration
4.3.1
PSSu assignment in system environment A
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 FS output):
"&" configuration (local enable principle)
}
Optimisation of ST process image by combining adjacent bits of the same type.
“*” configuration
