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
Figure 6
on page 17). 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: Avoid Retroreflective Installation
Do not install emitters and receivers in "retroreflective" mode, with less than a 45° angle of incidence,
as shown. Sensing may be unreliable in this configuration and result in a serious bodily injury
or death.

Emitter and Receiver Orientation
The emitter and receiver must be mounted parallel to each other and aligned in a common plane, with both cable ends
pointing in the same direction. Never mount the emitter with its cable end oriented in the opposite direction of the cable
end of the receiver. 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.
WARNING: Proper Orientation of System Emitters and Receivers
EZ-SCREEN Type 2 emitters and receivers must be installed with their corresponding cabled ends
pointing in the same direction (for example, both cabled ends facing up). Failure to orient them
properly will impair the performance of the EZ-SCREEN Type 2 System and will result in
incomplete guarding, and could result in serious bodily injury or death.
