1 Introduction
1.1 Validity of documentation
This documentation is valid for the products PSSu E F INC and PSSu E F INC-T. 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 INC and PSSu E F INC(-T) are exclusively for use in system envir-
onment B (automation system PSS4000).

This warning must be heeded! It warns of a hazardous situation that poses
an immediate threat of serious injury and death and indicates preventive
measures that can be taken.
WARNING!
This warning must be heeded! It warns of a hazardous situation that could
lead to serious injury and death and indicates preventive measures that can
be taken.
CAUTION!
This refers to a hazard that can lead to a less serious or minor injury plus
material damage, and also provides information on preventive measures
that can be taken.
NOTICE
This describes a situation in which the product or devices could be dam-
aged and also provides information on preventive measures that can be
taken. It also highlights areas within the text that are of particular import-
ance.

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:
}Inputs for
– Counter pulses (inputs A, B)
– Zero pulse (inputC)
– Stopping the counter (inputG, Gate)
– Memory function (Input L, Latch)
– Rotary encoder status (Input S, Status)
}Resolution of the counter and latch memory: 32 Bit
}Operating modes:
– Incremental encoder
– Counter
}Inputs A, B, C are operated as differential inputs with inverted signals (A-, B-, C-).
}LEDs for:
– Data transfer per input A, B, C
– Status per functional input (Gate, Latch, Status)
– Module error
}For failsafe applications in system environment B (automation system PSS 4000)
}T-type:
PSSu E F INC-T: for increased environmental requirements

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 INC and PSSu E F INC-T may be used as a safety components in
accordance with the Lifts Directive 95/16/EC in accordance with the requirements of
EN81-1/2:1998+A3:2009, EN81-20:2015, EN81-50:2015, EN81-22:2014 and
EN115-1:2008+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.
With the counter module you can implement the following safety functions:
Monitoring of:
}Position
}Speed
}Standstill
To guarantee safety integrity you will need to use
}2 sensors and
}2 counter modules: a PSSu E F INC and a PSSu E F ABS SSI and
}the function blocks FS_IncrementalEncoder, FS_AbsoluteEncoder and FS_Counter-
Dual
This means that with redundant and diverse input values, PL e and SIL CL 3 can be
achieved.
To apply the module you will need to have read and understood the description of the func-
tion blocks (s. Online help).
Requirements of the PSSu system:
}The counter modules must be part of a control system PSSu PLC or PSSu multi (not
decentralised I/O system).
}The function blocks have to be assigned to the FS resource of the PSSu system where
the counter modules are inserted. Control via SafetyNet is not permitted.
Demands on the sensors:
}Incremental encoders with RS422 interfaces may be used as sensors.
}Connect the sensors mechanically independently to the axis. If this is not possible, the
connection should be positive-locking without wearing parts as e.g. chains or drive
belts. If it is not possible to avoid this, the mechanical connection of the sensors must
be monitored.
Alternatively, it is possible to use a sensor that internally has 2 independent measured
value recording systems.
Please note during configuration and within the user program:
}The input values must be diverse. This can be achieved through different
– Scaling
