(5) Installation with some distance to prevent light interference
When installing the SL-V in method 2, 3 or 4, installing the devices too closely may cause reflection in the
plane of detection and thus cause interference. Total prevention of light interference may not be possible
even following methods 1 to 5. The operator in charge must consider adequate light interference preven-
tion method according to the machine or system where the SL-V is installed.
