Preface
Thank you for deciding in favour of our Programmable Safety Controller..
This instruction manual contains the description of PROTECT-PSC modules,
POWER modules, as well as the program description of the programming software
PROTECT-PSCsw.
Descriptions, control technical correlations, details on external control units, instal-
lation and operating information or similar have been provided to the best of our
knowledge. However, this does not mean that you may assume warranted charac-
teristics or other properties under liability law which extend beyond the “General
Terms of Delivery for Products and Services of the Electrical Industry”. We trust
you will understand that the user must therefore check our information and recom-
mendations before using the equipment.
In order to guarantee the safe operation of the product, these and all associated
instruction manuals must be read thoroughly and understood. They must be stored
in a safe place after reading and be accessible at the workplace at any time.
Please ensure that this instruction manual is made accessible to the end users of
the equipment.
We reserve the right to modify specifications and similar for the purpose of tech-
nical extension / improvement.
We would like to point out that under provisions of the law on foreign currency and
commercial transactions an export approval is to be obtained from the Japanese
government for the export of products and services for strategic use.
In the event of a defect occurring within the warranty period for which the manufac-
turer is responsible the repair or replacement of the defective part shall be pre-
formed at our discretion and at our expense. We trust you will understand that the
manufacturer is not liable for damage of a direct or indirect nature for which others
are responsible.
The reproduction of names, trade names, trademarks, etc. in this instruction man-
ual even if not especially marked as such, shall not entitle the user to assume that
such names are viewed as free within the meaning of trademark and brand name
protection law and may therefore be used by anyone.
Subject to technical amendments and error. The data used in this document are
carefully checked typical standard values.

1.1 Preface
We have prepared this document with due care to the best of our knowledge and
belief. Despite careful checking the possibility of it containing one or two errors
cannot be ruled out, however.
Before reading this instruction manual thoroughly, please read through chapter 2
carefully. Understanding the information and procedures described in this chapter
is essential for the correct use of the PROTECT-PSC Sicherheits-Kleinsteuerung
described in the following. Please always remember that faulty installation or pro-
gramming can lead to serious injuries / damage to man and machine.
The terms and abbreviations used in this document are standard terms used in
electrical engineering insofar as not described in more detail.
The basic operating functions of a computer with Microsoft Windows operating sys-
tem (as from Windows 2000) are assumed as generally known.
1.2 Definition of terms
The definition of the terms and the abbreviations used most frequently in this doc-
ument are described below.
Module In this document a module is described as an individual
physical unit which is a part of the PROTECT-PSC.
Active module A module which is actively involved in the change of state
of the PROTECT-PSC (corresponding to active
components in electronics).
Assembly An assembly consists of several individual modules.
Channel A physical input or output of a module.
A Contact Designation of an N/O contact
B Contact Designation of an N/C contact
User program The control program of the PROTECT-PSC created by
the programmer.
PS Programm Safety user program for CPU module (see chapter 3.7)
and Safety Input/Output modules.
PN Programm User program for non safe (operational) applications in
CPU module (see chapter 3.7) used with operational In-
put/Output modules.
PSV The PSV (Program Specific Value) is the checksum of
the user program.
FirmwareFB Safe function block inside the PROTECT-PSC
FB library Library of function blocks.
authorized person Person from group described in chapter 2.1.4.
Cat Abbreviation of Category (B, 1 to 4 according to
