Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reflectivity
Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resolution re-
sulting from the optical short circuit and use the corresponding depth penetration factor (Dpf or C) in the Safety Dis-
tance (Minimum Distance) formula; or mount the sensors in such a way that the receiver's field of view and/or the
emitter's spread of light are restricted from the reflective surface
Repeat the trip test (see
"Perform a Trip Test" on page 40 ) to verify these changes have eliminated the problem
reflection(s). If the workpiece is especially reflective and comes close to the defined area, perform the trip test with the
workpiece in place
Do not position reflective surfaces
within the shaded area

Operating range 0.1 to 3 m (4 in to 10 ft): d = 0.13 m (5 in)
Operating range > 3 m (>10 ft): d = 0.0437 x R (m or ft)
EZ-SCREEN SLS may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow un-
detected personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum speci-
fied emitter/receiver separation by approximately 8 percent per mirror, as follows:

See the specific mirror datasheet or www.bannerengineering.com for more information.
If mirrors are used, the difference between the angle of incidence from the emitter to the mirror and from the mirror to the re-
ceiver must be between 45° and 120° (see
" Using EZ-SCREEN SLS sensors in a retroreflective mode " on page 30 ). If placed
