"An example of supplemental safeguarding" on page 27 shows an example of supplemental safeguarding inside a robotic
work cell. The EZ-SCREEN SLS , in conjunction with the hard (fixed) guarding, is the primary safeguard. Supplemental safe-
guarding (such as a horizontal-mounted safety light screen as an area guard) is required in areas that cannot be viewed from
the reset switch (for example, behind the robot and the conveyor). Additional supplemental safeguarding may be required to
prevent clearance or trapping hazards (for example, a safety mat as an area guard between the robot, the turntable, and the
conveyor).
WARNING:
The hazard must be accessible only through the sensing field
Incorrect system installation could result in serious injury or death.
The installation of the EZ-SCREEN SLS must prevent any individual from reaching around, under,
over or through the defined area and into the hazard without being detected.
See OSHA CFR 1910.217, ANSI B11.19, and/or ISO 14119, ISO 14120 and ISO 13857 for infor-
mation on determining safety distances and safe opening sizes for your guarding device. Mechani-
cal barriers (for example, hard (fixed) guarding) or supplemental safeguarding might be required to
comply with these requirements.
The emitter and receiver must be mounted parallel to each other and aligned in a common plane, with both machine interface
cable ends pointing in the same direction.
Never mount the emitter with its machine interface cable end oriented in the opposite direction of the cable end of the receiv-
er. If this occurs, voids in the light screen may allow objects or personnel to pass through the defined area undetected.
The emitter and receiver may be oriented in a vertical or horizontal plane, or at any angle between horizontal and vertical, as
long as they are parallel to each other and their cable ends point in the same direction. Verify that the light screen completely
covers all access to the hazard point that is not already protected by hard (fixed) guarding or other supplemental guarding.
