Installation
IMPORTANT: The sensor and the re ector MUST be mounted vertically. Disconnect ALL power to the
operator.
1. Attach the mounting bracket to the post with 1/4"-20 screws. Drill a hole in the post through the center
hole in the bracket. Optional: If installing to a square post or fl at 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 specifi ed 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 fi tting (not provided).
7. Place the refl ector in the refl ector hood.
8. Secure the refl ector and hood to the bracket with 8-32x1" screws. Secure the bottom of the refl ector to the
hood with 8-32x1" screws.
9. Mount the re ector a minimum of 3 ft. (.9 m) and maximum of 50 ft. (15.2 m) away from the sensor.
