Test Instructions
The purpose of the tests described in the following is to con-
firm the safety requirements specified in the national/internati-
onal rules and regulations, especially the safety requirements
in the Machine and Work Equipment Directives (EU Conformity).
These tests are also used to identify if the protection is af-
fected by external light sources or other unusual ambient effects.
These tests must therefore always be performed.
7.1
Pre-commissioning tests
! Inspection prior to commissioning is used to confirm com-
pliance with the safety requirements specified in national or
international regulations, in particular the machinery safety
regulations or the provision and use of work equipment re-
gulations.
! Inspection of the effectiveness of the protection equipment
on the machine in all the operating modes in which the ma-
chine can be placed.
! Qualified personnel must, prior to starting work, instruct the
personnel operating the machine protected by the safety de-
vice. Instruction is the responsibility of the machine opera-
ting company.
Incorrect installation may lead to non-detection of an obstacle,
or to operating safety levels not being achieved.
The light beam must not be unintentionally reflected by reflec-
ting surfaces. Reflections can be detected as follows:
Using an object (surface: 100 x 100 mm
