Precaution on use
 Operators
 Environment of use
 Target machine
DANGER
• In order to operate the GL-RHG correctly, the responsible personnel and machine
operators must fulfill all of the procedures described in this user's manual.
• No person other than the responsible personnel and machine operators should be
allowed to install or test the GL-RHG.
• When performing electrical wiring, always fulfill the electrical standards and regulations
for the country or region in which the GL-RHG is used.
DANGER
• Do not use the GL-RHG 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-RHG 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-RHG.)
• The GL-RHG 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-RHG in the presence
of substances, such as heavy smoke, particulate matter, or corrosive chemical agents.
• Do not install the GL-RHG in areas where the GL-RHG 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
override function is activated. Failure to follow this warning results in significant harm to
the machine operators, including serious injury or death.
DANGER
• When using GL-RHG as a press machine safety device in Japan, press machines other
than those fulfilling the following specifications cannot be used.
• When using GL-RHG as a shearing machine (paper cutting machine) safety device in Japan, shearing
machines (paper cutting machines) other than those fulfilling the following specifications cannot be used.
• The machine on which the GL-RHG is to be installed must be susceptible to an
emergency stop at all operating points during its operation cycle. Do not use the GL-RHG
for machines with irregular stop times.
• Do not use the GL-RHG for power presses equipped with full-revolution clutches.
• The GL-RHG 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-RHG 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-RHG is designed to protect people or objects from going into/approaching
protective 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.
