General Protective Notes and Protective Measures
The national/international rules and regulations apply to the
installation, use and periodic technical inspections of the safety light
curtain, in particular:
• Machine Directive 98/37/EEC
• Equipment Usage Directive 89/655/EEC
• The work safety regulations/safety rules
• Other relevant health and safety regulations
Manufacturers and operators of the machine with which the safety
light curtain is used are responsible for obtaining and observing all
applicable safety regulations and rules.
• The notices, in particular the test regulations (see “Test Notes”
on page 31) of these operating instructions (e.g. on use,
mounting, installation or integration into the existing machine
controller) must be observed.
• Changes to the configuration of the devices can modify the
protective function. After every change to the configuration you
must therefore check the effectiveness of the protective device.
The person who makes the change is also responsible for the
correct protective function of the device. When making
configuration changes, always use the password hierarchy
provided by Allen-Bradley Guardmaster to ensure that only
authorized persons make changes to the configuration.
• The tests must be carried out by specialist personnel or specially
qualified and authorized personnel and must be recorded and
documented to ensure that the tests can be reconstructed and
retraced at any time.
• The operating instructions must be made available to the
operator of the machine where the SafeShield safety light curtain
is installed. The machine operator is to be instructed in the use of
the device by specialist personnel and must be instructed to read
the operating instructions.
• The external voltage supply of the device must be capable of
buffering brief mains voltage failures of 20ms as specified in
EN 60204-1. Suitable power supplies are available as accessories
from Rockwell Automation.
