Installation
2.1 Install the Safety Label
The safety label must be installed on Q3X sensors that are used in the United
States.
Note:
Position
the label on the cable in a
location
that has minimal
chemical exposure.
1. Remove the
protective
cover from the adhesive on the label.
2. Wrap the label around the Q3X cable, as shown.
3. Press the two halves of the label together.

2.2 Sensor
Orientation
Correct sensor-to-target
orientation
is important to ensure proper
sensing. To ensure reliable
detection,
orient the sensor as shown in
relation
to the target to be detected.
For models with background suppression, make sure the intended target
is inside of the contrast sensing range and that any background objects
are
positioned
beyond the background suppression distance.

Mounting
1. If a bracket is needed, mount the sensor onto the bracket.
2. Mount the sensor (or the sensor and the bracket) to the machine or equipment at the desired
location.
Do not
tighten
at this
time.
3. Check the sensor alignment.
4. Tighten the screws to secure the sensor (or the sensor and the bracket) in the aligned
position.
