EZ-SCREEN
Type 2 Light Screen
Mounting Hardware
The EZ-SCREEN standard end-cap mounting bracket hardware is
supplied with each emitter and receiver. Brackets are designed to
mount directly to MSA Series stands using the hardware with the
supplied stands.
Using Center Mounting Brackets
Center mounting brackets are supplied with longer sensors and
must be used whenever the sensors are subject to shock or
vibration. The sensors are designed to be mounted with up to 450
mm (18 in) distance between brackets:
•
Sensors 600 to 900 mm (24 in to 36 in) long are supplied
with one center bracket, which should be centered on the
sensor.
•
Sensors 1050 to 1350 mm (42 in to 54 in) long are
supplied with two center brackets, which should be
positioned 1/3 of the sensor's length from each sensor
end.
•
Sensors 1500 to 1800 mm (59 in to 71 in) long are
supplied with three center brackets
To install each bracket:
1. Spread the clamp and snap over the back of the sensor so
that the clamp is securely fastened to the sensor without
blocking any beams.
2. Compress the foam spacer and slide the clamp along the
length of the sensor housing to align the clamp with the
center mounting bracket as shown in
20. Three separate mounting holes are provided on the
clamp to allow for all possible mounting configurations.
3. Connect the clamp to the center bracket using the M3
screw supplied.
4. Loosen all the mounting screws to the sensor, align the
sensors and then tighten the end screws. Finally, tighten
the M3 screw joining the clamp to the center mounting
bracket.
3.2.2 Mounting and Initial Alignment of Emitter/Receiver Pairs
Emitter/receiver pairs may be spaced from 0.2 to 15 m (8 in to 50 ft) apart. The maximum distance between an emitter and its receiver
is reduced if corner mirrors are used. The supplied brackets (when mounted to the sensor end caps) allow ±30° rotation.
To mount each emitter/receiver pair:
1. From a common point of reference (ensuring the calculated safety distance), make measurements to locate the emitter and
receiver in the same plane with their midpoints directly opposite each other.
