1 About this document
These operating instructions contain information required during the life cycle of the
safety light curtain.
These operating instructions are available to all those who work with the safety light
curtain.
Please read these operating instructions carefully and make sure that you understand
the content fully before working with the safety light curtain.
1.1 Scope
These operating instructions only apply to the deTec4 Ex safety light curtain with one of
the following type label entries in the “Operating Instructions” field:
•8022831
This document is included with the following SICK part numbers (this document in all
available language versions):
8022831
1.2 Target groups and structure of these operating instructions
These operating instructions are intended for the following target groups: Project devel‐
opers (planners, developers, designers), installers, electricians, safety experts (e.g., CE
authorized representatives, compliance officers, persons who test and approve the
application), operators, and maintenance personnel.
The structure of these operating instructions is based on the life cycle phases of the
safety light curtain: Project planning, mounting, electrical installation, commissioning,
operation, and maintenance.
In many applications, the target groups are assigned as follows to the manufacturer
and the organization operating the machine in which the safety light curtain is inte‐
grated:
