DANGER
• The installation of the indication for override may be required by the laws, rules,
regulations, and standards in the country or region in which the GL-RHG is used if you
apply the override function. It depends on the machine application and/or the result of
your risk assessment. If it is necessary for you to provide the indication for override, you
must fulfill the requirements because you are fully responsible for installation of the
indication for override.
• Only the responsible personnel must be allowed use or activation of the override
function.
• Those who use the override function must fulfill all requirements related to the override
function. KEYENCE accepts NO responsibility and NO liability for any damage or any
injury due to the unauthorized installation, usage, or maintenance, which are not
specified in this user's manual, and/or due to noncompliance with the laws, rules,
regulations and standards in the country or region in which the GL-RHG is used.
