PHYSICAL SPECS

DESCRIPTION AND OPERATIONThe MEW-OS100W Occupancy sensor is designed to replace a standard light or fan switch. It is ideal for conference rooms, break rooms, lounges, storage areas, private offices and closets.

Sensor Operation

The sensor’s relay is shipped in a closed position that turns the load onupon initial power-up. The connected load will stay on for about80 seconds to allow the PIR sensor to initialize.

Initial Power Up (80 Seconds Warm up)

The sensor detects changes in the infrared energy given off by occupants as they move within the coverage area. When occupancy is detected, a self-contained relay switches the connected load on. The sensor is line powered and can pass-thru the line voltage (Refer to Max Load for limitation). An internal timer automatically turn off the load after a selectable period of inactivity.

Coverage Area• Designed for 10 to 15 ft (3.05m to 4.60m) mounting heights.• 10 to 20 ft (3.0 to 6.1 m) radial coverage overlaps area lit by a typical high bay fixture (Refer to Fig1)

INSTALLATION & WIRING

WARNINGDisconnect power to the mounting box by turning OFF the circuit breaker or removing the fuse for the circuit before installing the

MEW-OS100W, replacing Lamps, or doing any electrical work.

CAUTION FOR YOUR SAFETY:IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS. PLEASE CONSULT A QUALIFIED ELECTRICIAN.

Avoiding HVAC TurbulenceHeating, Ventilating or Air Conditioning (HVAC) can create turbulence which can cause the sensor to activate. It is important that the sensor and HVAC register be separated by at least 6'.

If the sensor's location gives it a view of other rooms or hallways, the load will turn on when movement is detected in these adjacent areas. The sensor's detection zone may be restricted by masking a portion of the lens.

In addition, it is also NOT recommended to mount the MEW-OS100Wunder or near a large light source. Large wattage bulb (greater than 100Wincandescent) create a lot of heat. Turning these bulbs on cause a rapidtemperature changes that can create a false trigger on the sensor.

Sensor Installation1.Turn off Circuit breaker.2.Determine the best location for the sensor. Install the sensor at least 3 ft. away from fluorescent ballasts and HVAC ducts, and at least 4 ft. away from incandescent fixtures and HVAC diffusers.3.Connect the wires per Wiring Diagram: BLACK lead to LINE(HOT), RED lead to LOAD, WHITE lead to NEUTRAL. Twist the existing wires together with the wire leads of the MEW-OS100W sensor as shown below. Cap them securely using the wire nuts provided.4.Remove the Sensor’s back plate by holding the plate and twisting the sensor counter-clockwise.5.Secure the back plate with the standard Ceiling box using the two screws provided.6.Mount the sensor with the plate. Restore power at circuit breaker or fuse box.

SENSOR ADJUSTMENT & PROGRAMMING

Timeout KnobThe “TIME” knob sets the ON time of the load after inactivity. Thetime is reloaded after each detection.Turn the adjustment knob fully counter clockwise to the minimum setting (Marked 1 (TEST)) to have a short delay time andtest the sensor. The delay for TEST mode is 15 seconds. You can select your preferred setting by adjusting the knob to the desired time (5, 10,20 or 30 Minutes)

Sensitivity KnobThe “SENSE” knob sets the sensitivity of the occupancy detection.

This knob is adjustable from 50% (Position 1) to 100% (Position 5)Turning the knob clockwise will increase the sensitivity while turning it counter-clockwise will decrease it. Maximum sensitivity is achievedby turning the knob fully clockwise to Position 5

Ambient Light Level KnobThe “LIGHT” knob sets the threshold of the ambient light necessary toactivate the load. Your load will only turn on if the natural lighting in theroom is low.If the low lighthing feature is not desired, position the knob on the maximum setting (Position 5). This will allow the occupancy sensor to turn on the load regardless of the ambient lighting condition.

TROUBLESHOOTINGLoad will not turn ON• Circuit breaker or fuse is OFF: Turn the breaker ON. Ensure the lights being controlled are in working order (i.e., working bulbs. ballasts, etc.)• Sensor is wired incorrectly or may be defective: Confirm that the sensor's wiring is done correctly and inspect visually for problems.• Lens is dirty or obstructed: Inspect the lens visually and clean if necessary, or remove the obstruction.

Load will not turn OFF• Make sure no motion is occurring in the coverage area during the 15 sec. time delay (in “TEST” Timeout). Sensor is wired incorrectly or may be defective: Confirm that the sensor's wiring is done correctly and inspect visually for problems. Sensor may be mounted too close to an air conditioning or heating vent: Move the sensor or turn off the vent.• The line voltage has dropped: Perform the necessary tests to ensure the line voltage is not beneath 100V

Lights turn ON and OFF too quickly• Sensor may be mounted too close to an air conditioning or heating vent: Move the sensor to another location or turn off the vent.• Time delay set improperly: Refer to Time delay Adjustment WARRANTYMaxxima extends a 1 year limited warranty to the original purchaser that the products purchased are free from defects in material and/or workmanship only.
