Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
Mounting the Sensors
All system components (emitter, receiver, and corner mirrors, if used), must be
parallel to each other and perpendicular to the floor. If the floor is level, the
components may be checked for plumb, using a level, for example. If the floor is
sloped, alignment is more complex, because the floor-to-bottom-beam measurement
must remain constant, or not exceed the maximum height above the floor.
If the floor has a dip, as for a drain, or is raised up within the path of the beams,
corrective measures must be taken to ensure that the requirements of ANSI/RIA
R15.06, ANSI B11, or EN999 are met (see Figure 3-10). It is important that the
distances between the grid’s top and bottom beams and the floor meet the
requirements of the applicable standards, throughout the length of the beam path.
Installation Without Mirrors
1. If using Banner MSA series stands and bases to mount the EZ-SCREEN emitter
and receiver, position the bases at the desired locations and loosely mount using
the bolt locations in the four corners as described in the MSA literature. Do not
tighten the mounting nuts, because the stand and sensor must still be leveled.
Other stands and bases may be used to mount the EZ-SCREEN system, but must
allow the sensors to tilt (both front-to-back and side-to-side) to accommodate
sloping floor surfaces and the alignment procedure. When fixed stands and bases
are used, the EZA-MBK-9 brackets may be used to provide the necessary
adjustability for alignment.
2. Mount the emitter and the receiver, using the supplied EZ-SCREEN mounting
brackets, so that the beam closest to the floor is at the proper height, typically no
more than 12" from the floor. Refer to the appropriate standards for specifics on
the correct mounting of EZ-SCREEN Grid systems. Do not fully tighten the screws
until the sensor is aligned.
3. Position the emitter and receiver housings so that they are perpendicular to the
floor in all dimensions, with their windows facing each other. If the floor is level,
use a level to check for plumb.

applicable standards.
