1 Introduction
1.1 Validity of documentation
This documentation is valid for the product types PSSu E F AI U, PSSu E F AI U-T and
PSSu E F AI U-R. It is valid until new documentation is published.
This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
1.1.1 Retaining the documentation
This documentation is intended for instruction and should be retained for future reference.
1.1.2 Terminology: System environment A and B
The PSSu system can be used in two different system environments. The module's applic-
ation area is described in the chapter "Intended Use" of the manual.
The distinction is made between
}PSSu in system environment A
}PSSu in system environment B
The distinction is based on the application area of the PSSu system.
PSSu in system environment A may be used in the
}Decentralised system PSSu I/O
}Not in the automation system PSS 4000
PSSu in system environment B may be used in the
}Automation system PSS 4000, e.g. with
– Decentralised system PSSu I/O with SafetyNET p
– Control system PSSu PLC
– Control system PSSu multi
The modules PSSu E F AI U and PSSu E F AI U(-T)(-R) are exclusively for use in system
environment B (automation system PSS 4000).

2 Overview
2.1 Module structure
A module consists of
}Electronic module and
}Base module with
– Screw terminals or
– Cage clamp terminals
The base modules are the carrier units for the electronic modules and are used to connect
the field wiring. The electronic modules are inserted on to the base modules and determine
the module's function.
Details of the base modules that can be used are available in the chapter entitled “Intended
Use”.
2.2 Module features
The product has the following features:
}1 Analogue voltage input
}Voltage range:
-10.24 V ... +10.2375 V Dual-pole, differential input
}Resolution:
13 Bit (representation of negative values in the two's complement)
}LEDs for:
– Operating status per input
– Module error
}For failsafe applications in system environment B (automation system PSS 4000)
}T-type:
PSSu E F AI U-T: for increased environmental requirements
}R-type:
PSSu E F AI U-R: for railway applications

3 Safety
3.1 Intended use
The module may be used for failsafe applications in system environment B (automation
system PSS 4000).
The modules PSSu E F AI U and PSSu E F AI U-T may be used as a safety components in
accordance with the Lifts Directive 95/16/EC in accordance with the requirements of
EN81-1/2:1998+A3:2009, EN81-20:2015, EN81-50:2015, EN81-22:2014 and
EN115-1:2008+A1:2010.
The programmable safety system should be installed in a protected environment that meets
at least the requirements of pollution degree 2. Example: Protected inside space or control
cabinet with protection class IP54 and corresponding air conditioning.
The module provides an analogue input.
To guarantee safety integrity you will need to use 2 analogue input modules (2 PSSu E F AI
U or one PSSu E F AI U + one PSSu E F AI I). PL e (Cat. 4) and SIL CL 3 can be achieved
as a result of redundant input data.
The module guarantees functional safety, but not the safety of the entire process.
Please note the following during configuration and within the user program:
}With 2-channel operation, check the feasibility by using two inputs and two sensors.
Take appropriate measures to avoid common cause errors in the sensor technology, by
using diverse sensors or a separate supply voltage for the sensors, for example.
}We recommend that you monitor a defined measuring range of 2 … 10 V, as an open
circuit or short circuit cannot be detected at 0 V, for example.
The measured value is attenuated through the input filter. At the cutoff frequency, the amp-
litude of the measured value is 70 % of the amplitude of the input signal.
We strongly recommend the use of the following function blocks:
}FS_AnalogueInputSingle (using one input)
}FS_AnalogueInputDual (using two inputs)
The function blocks contain "Feasibility check" (only on FS_AnalogueInputDual) and "Limit
value monitoring" functions, which enable you to detect errors in the sensor as well as the
wiring. For the "Range monitoring" function we recommend that you use a measuring range
of 2 … 10 V.
The module PSSu E F AI U-T is suitable for use where there are increased environmental
requirements (see Technical Details).
The module PSSu E F AI U-R is suitable for use where there are increased environmental
requirements demanded by railway applications (see Technical details).
Intended use includes making the electrical installation EMC-compliant. Please refer to the
guidelines stated in the "PSSuniversal Installation Manual". The module is designed for use
in an industrial environment. It is not suitable for use in a domestic environment, as this can
lead to interference.
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the module
