Westgate WEC-3MDR-42 Manual

Bi-level Microwave Sensor For High Bay Light
INTRODUCTION
The WEC-3MDR-42 is a motion sensor that dims lighting from high to low based on movement. This slim,
low- profile sensor is designed for installation inside the bottom of a light fixture body. The sensor plus
module connects to the BRI816-B-D sensor socket through a 1.30" diameter hole in the bottom of the fixture.The
sensors use microwave sensing technology that reacts to changes in movement within the coverage area.
Once the sensor stops detecting movement and the time delay elapses lights will go from high to low mode and
eventually to an OFF position if it is desired. Sensors must directly "see" motion of a person or moving object to
detect them, so careful consideration must be given to sensor luminaire placement and lens selection. Avoid
placing the sensor where obstructions may block the sensor's line of sight.

the sensor will wait and monitor for 1 min in order to confirm the light level increase is not temporary before forcing the lights
to go off. When light level goes below the settings, the light will turn on even without motion detection after 1min. This feature
is disabled by default.

INSTALLATION
1. Determine an appropriate mounting location inside the light fixture minimizing the electric light contribution
to the sensor's photocell. Allow a minimum distance of 0. 2" (5.1mm) from the wiring end of the sensor to
the wall of the fixture.
2. Drill a hole 1.30"(33. 0mm) in diameter through the sheet metal in the bottom of the fixture.
3. Add the rubber gasket to the threaded collar, and install the sensor face down, parallel to the mounting
surface. Ensure the rubber gasket touches the inside surface of the fixture. Install the plastic nut securely
against the fixture to a torque of 25-30 in-lbs to ensure IP rating is maintained.
4. Align the locking features between the sensor socket and the sensor plug and push the sensor plug forward
until the o-ring seals firmly. Turn the sensor plug clockwise to ensure it locks in place.
