KEYENCE GL-R Series - Manual (Page 12)

12 E GL-R-IM
 Regular (periodical) inspection
The responsible personnel must perform a regular inspection.
It is recommended to perform a regular inspection at least once every six months.
Note that the following inspection items comprise only a bare minimum inspection. KEYENCE
Corporation strongly recommends including the necessary checking items into this checklist based on
the judgment of the responsible personnel since additional criteria may be necessary depending on both
the machine to which the GL-R is installed and the laws, rules, regulations and standards in the country
or region in which the GL-R is used/installed.
The result of this inspection must be kept on record along with the machine log.
(1) Additional inspection items

The actual distance between the hazardous zone or hazards and the GL-R still keeps greater than
the calculated safety distance.
 When the reduced resolution function is applied, the safety distance is accurately calculated based
on the enlarged detection capability, and the GL-R is installed at a distance greater than or equal to
the minimum safety distance away from the hazardous zone or hazard.
 When the fixed blanking function is applied, a hazardous clearance that is not protected by the GL-R
may be generated between the obstacle and the GL-R. When such a hazardous clearance is
generated, an additional protective device such as a safeguard is installed.
 The stop time of the machine connected to the GL-R has not increased.
 There are no loose screws in the mounting bracket.
 The unit connection cable or the series connection cable is fastened tightly to the GL-R with no loose
screws.
 The OSSD is connected correctly to the machine.
 There is no damage to the GL-R that may influence IP65 structure.
 The surface of the GL-R is not polluted or damaged.
 Beam axes must be aligned. If it is out of alignment, beam axes are aligned.
 There is no change of installation that would influence the result of your original risk assessment.
