DANGER
• You must verify that the GL-T11R is operating correctly in terms
of functionality and performance before starting the machine.
• KEYENCE does not guarantee the functions and performance
of the GL-T11R if it is used in a manner that differs from the
GL-T11R specifications described in this instruction manual or
if the GL-T11R is modified by the customer.
• When using the GL-T11R to protect machine operators against a
hazard or hazardous zone or using the GL-T11R as a safety com-
ponent for any purpose, always follow the applicable require-
ments of the laws, rules, regulations and standards in the country
or region where the GL-T11R is used. For such regulations, you
should make direct contact with the regulatory agency responsi-
ble for occupational safety and health in your country or region.
• Depending on the type of machine on which the GL-T11R is to
be installed, there may be special safety regulations related to
the use, installation, maintenance, and operation of the safety
component, and such safety regulations must be fulfilled. The
responsible personnel must install the GL-T11R in strict com-
pliance with such safety regulations.
• The responsible personnel must do the training to the assigned
personnel for the correct use, installation, maintenance, and
operation of the GL-T11R. "Machine operators" refers to person-
nel who have received appropriate training from the responsible
personnel and are qualified to operate the machine correctly.
• Machine operators must have specialized training for the GL-T11R,
and they must understand and fulfill the safety regulations in the
country or region in which they are using the GL-T11R.
• When the GL-T11R fails to operate, machine operators must
immediately stop the use of the machine and the GL-T11R and
report this fact to the responsible personnel.
• The GL-T11R is designed with the assumption that it would be cor-
rectly installed and operated in accordance with the installation
and operation procedures described in this instruction manual.
You must perform an appropriate installation of the GL-T11R after
conducting a sufficient risk assessment for the target machine.
• When disposing of the GL-T11R, make sure to follow require-
ments, rules, codes, regulations and laws regarding industrial
wastes in countries or regions where the GL-T11R is used.
• The GL-T11R should be processed as an industrial waste prod-
uct when being disposed.
DANGER
• In order to operate the GL-T11R correctly, the responsible per-
sonnel and machine operators must follow all procedures
described in this instruction manual.
• No person other than the responsible personnel and machine
operators should be allowed to install or test the GL-T11R.
• When performing electrical wiring, always fulfill the electrical
standards and regulations for the country or region in which
the GL-T11R is used.
DANGER
• The GL-T11R is not designed to be explosion-proof. Never use it
in the presence of flammable or explosive gases or elements.
• When using the GL-T11R in the presence of substances, such as heavy
smoke, particulate matter, or corrosive chemical agents, confirm that
such substances do not induce deterioration in product quality.
• Be sure to confirm absolutely that there is nobody in the
hazardous zone, before the interlock is released (i.e. the
machine system restarts) by the interlock reset mechanism.
Failure to follow this warning may result in significant harm to
the machine operators, including serious injury or death.
• Interlock reset mechanisms (such as switches) must be
installed so that the whole hazardous zone can be checked by
the responsible personnel. Interlock reset mechanisms should
not be accessible from within the hazardous zone.
• Use the GL-T11R within an enclosure of IP54 or higher.
• Ensure there is space around the unit for ventilation.
• Do not install the GL-T11R in the locations listed below:
•
Locations with high humidity and a risk of condensation
• Locations where water will splash onto the GL-T11R
• Locations where there are corrosive gases
• Locations where any flammable gases or explosive gases
exist
• Locations where the GL-T11R may be directly subjected to
vibration or impact
• Locations where strong electromagnetic noise may affect the
GL-T11R
