• Repeat the trip test (see
Trip Test
on page 32) 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

5.2.7 Use of Corner Mirrors
EZ-SCREEN may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow
undetected personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum
specified emitter/receiver separation by approximately 8 percent per mirror, as follows:

See the specific mirror data sheet or
If mirrors are used, the difference between the angle of incidence from the emitter to the mirror and from the mirror to the
receiver must be between 45° and 120° (see
on page 27). If placed at a sharper angle, an object in the light
screen may deflect beam(s) to the receiver, preventing the object from being detected, also know as false proxing. Angles
greater than 120° result in difficult alignment and possible optical short circuits.
WARNING:
• Retroreflective Mode Installation
• Failure to follow these instructions may create unreliable sensing and may result in serious injury
or death.
• Do not install emitters and receivers in retroreflective mode with less than a 45° angle of
incidence. Install emitters and receivers at an appropriate angle.
