• KEYENCE does not guarantee the function or performance of the GL-R if it is used in a

manner that differs from the GL-R specifications contained in this user's manual or if

the GL-R is modified by the customer.

• When using the GL-R to protect machine operators against a hazard or hazardous zone

or using the GL-R as a safety component for any purpose, always follow the applicable

requirements of the laws, rules, regulations and standards in the country or region

where the GL-R is used. For such regulations, you should directly contact to the

regulatory agency responsible for occupational safety and health in your country or

region.

• Depending on the type of machine on which the GL-R is to be installed, there may be

special safety regulations related to the use, installation, maintenance, and operation of

the safety component. In such a case, you must fulfill such safety regulations. The

responsible personnel must install the GL-R in strict compliance 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-R. "Machine operators"

refers to personnel 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-R, and they must

understand and fulfill the safety regulations in the country or region in which they are

using the GL-R.

• When the GL-R fails to operate, machine operators must immediately stop the use of the

machine and the GL-R and report this fact to the responsible personnel.

• The GL-R is designed with the assumption that it would be correctly installed in

accordance with the installation procedures described in this user's manual and

correctly operated according to the instructions in this user's manual. You must

perform an appropriate installation of the GL-R after performing a sufficient risk

assessment for the target machine.

• Be sure to absolutely confirm that there is nobody in the hazardous zone, before you

remove the GL-R from the machine for replacement or disposal.

• When disposing the GL-R, always follow the applicable requirements of the laws, rules,

regulations and standards in the country or region where the GL-R is used.

DANGER

• Do not use the GL-R in an environment (temperature, humidity, interfering light, etc.)

that does not conform to the specifications contained in this user's manual.

• Be sure to confirm that the GL-R keeps normal operation when electromagnetic

radiation is generated by wireless devices. (If you use wireless devices such as cellular

phones or transceivers in the vicinity of the GL-R.)

• The GL-R is not designed to be explosion-proof. Never use it in the presence of

flammable or explosive gases or elements.

• Be sure to confirm no deterioration in product quality if you use the GL-R in the

presence of substances, such as heavy smoke, particulate matter, or corrosive chemical

agents.

• Do not install the GL-R in areas where the GL-R is exposed to intense interference light

such as direct sunlight, and direct or indirect light from an inverter-type fluorescent

lamp (rapid-start type lamp, high-frequency operation type lamp, etc).

• Be sure to absolutely confirm 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 results in significant harm to the machine

operators, including serious injury or death.

• Be sure to absolutely confirm that there is nobody in the hazardous zone before the

override function is activated. Failure to follow this warning results in significant harm

to the machine operators, including serious injury or death.

DANGER

• The GL-R has not undergone the model certification examination in accordance with

Article 44-2 of the Japanese Industrial Safety and Health Law. The GL-R, therefore,

cannot be used in Japan as a "Safety Device for Press and Shearing machines" as

established in Article 42 of that law.

• The machine on which the GL-R is to be installed must be susceptible to an emergency

stop at all operating points during its operation cycle. Do not use the GL-R for machines

with irregular stop times.

• Do not use the GL-R for power presses equipped with full-revolution clutches.

• The GL-R cannot be used as a PSDI because it does not fulfill the requirements of OSHA

1910.217(h). Refer to OSHA 1910.217 for the PSDI mode.

• Do not use the GL-R to control (stop forward motion, etc.) trains, cars and other

transportation vehicles, aircraft, equipment for use in space, medical devices, or

nuclear power generation systems.

• The GL-R is designed to protect people or objects from going into/approaching

detection zone against machine's hazard or hazardous zone. It cannot provide

protection against objects or materials that are expelled from the machine's hazard or

hazardous zone, so you must establish additional safety measures such as installing

safeguards when there is the possibility of such projectiles.

DANGER

• The GL-R must be installed only after ensuring the minimum safety distance between

the GL-R and the hazardous zone or hazard as established by the applicable regulations

in the country or region in which the GL-R is used. (e.g. EN ISO13855 (ISO 13855) in EU

countries)

• Choose locations for the installation of the GL-R transmitters and receivers so that they

are not subject to the effects of light reflected from glossy surfaces in the area.

• Correct operation and detection is not possible if the receiver has a different beam axis

spacing (detection capability) from that of the transmitter. You must verify that the beam

axis spacing (detection capability) is the same between the transmitter and the receiver

when installing the GL-R.

• The GL-R must be installed so that the machine operator is able to go into or approach

the hazardous zone or hazards only by passing through the detection zone of the GL-R.

Strictly avoid installation that allows the machine operator or a part of the machine

operator's body to go into or approach the hazardous zone or hazards without passing

through the protective zone of the GL-R or to remain in position between the protective

zone of the GL-R and the hazardous zone or hazard. In a case where you install the GL-R

units in series (series connection), you must always check the installation carefully

whether you follow this warning, especially after installation and maintenance.

• You must always perform the pre-check tests after installing the GL-R in accordance

with the pre-check test procedures, such as items specified in this user's manual, in

order to verify that the test pieces can be detected in all of the detection zones.

• Interlock reset mechanisms (such as switches) must be installed so that the entire

hazardous zone can be checked by the responsible personnel. Interlock reset

mechanisms should not be accessible from within the hazardous zone.

• Muting is a function to allow a temporary automatic suspension of the GL-R safety

functions while the GL-R is receiving a signal from muting devices (such as sensors or

switches). Therefore, additional safety measures are required for the machine on which

the GL-R is installed in order to ensure safety while the muting is activated.

• Muting devices, the installation of those devices and the procedure to activate the

muting function must fulfill the conditions specified in this user's manual and the

requirements of the laws, rules, regulations and standards in the country or region in

which the GL-R and those devices are used. Failure to follow this warning may result in

significant harm to the machine operators, including serious injury or death.

• When you install muting devices (such as sensors or switches) for muting, the following

conditions must be fulfilled.

(1) Muting devices must be installed so that the muting cannot be activated if the

hazardous zone of the machine is in an unsafe condition or cycle.

(2) Muting devices must be installed so that the muting cannot be activated even if the

personnel is accidentally approaching the detection zone of the GL-R.

• The muting device must be installed such that only responsible personnel have access

to that device to change the installation or orientation. Special tools must be required to

ensure that only responsible personnel are capable of installation, orientation or change

of muting device.

• Only the responsible personnel may be allowed to install or wire the devices to activate

the muting function.

• The installation of a muting lamp may be required by the laws, rules, regulations, and

standards in the country or region in which the GL-R is used if you apply the muting

function. It depends on the machine application and/or the result of your risk

assessment. If it is necessary for you to provide a muting lamp, you must fulfill the

requirements because you are fully responsible for installation of the muting lamp.

• The override is a function to allow a temporary manual suspension of the safety

functions of the GL-R. Therefore, additional safety measures are required for the entire

machine system on which the GL-R is installed in order to ensure safety while the

override is activated.

• The override devices, the installation of those devices and the procedures to activate

the override must fulfill the conditions specified in this manual as well as the

requirements of the laws, rules, regulations and standards in the country or region in

which the GL-R and those devices are used. Failure to follow this warning may result in

significant harm to the machine operators, including serious injury or death.

• The override devices, which are used for activation of override, must be manual

operating devices. When installing the devices to activate the override, those devices

must be installed so that the whole hazardous zone can be checked by the responsible

personnel and so that it is not possible for machine operators to operate those devices

in the hazardous zone.
