Optional:
If installing to a square post or flat surface, you may attach the sensor
bracket directly to the post without using the mounting bracket.
Make sure the location of the sensor
follows the specified measurements. If installing multiple sensors in close proximity, mount the sensors on
opposite sides to avoid crosstalk.
2.
Slide the bottom sensor bracket onto the studs of the mounting bracket and secure with 1/4"-20 lock nuts.
Make sure the bracket legs are facing down.
3.
Loosely attach the top sensor bracket with 10-32x1" thread-locking screws.
Make sure the slots are
facing up.
4.
Place the sensor in the bracket and tighten the screws just enough to allow the sensor to rotate inside the
bracket.
5.
Slide the hood over the sensor until it snaps into place. Secure hood with the M3 screw. The hood MUST
be installed on the sensor.
6.
Route wires through the center hole of the mounting bracket and into the post.
Optional:
Use conduit with
NEMA 4X compatible 1/2"-14 NPT fitting (not provided).
7.
Place the reflector in the reflector hood.
8.
Secure the reflector and hood to the bracket with 8-32x1" screws. Secure the bottom of the reflector to the
hood with 8-32x1" screws.
9.
Mount the reflector a minimum of 3 ft. (.9 m) and maximum of 50 ft. (15.2 m) away from the sensor.
