Description and Operation
The YM2501A occupancy sensor is designed to replace a standard light or fan switch. It is ideal for high mounted areas such as warehouses, manufacturing and other high-ceiling applications

Sensor Operation
The sensor detects changes in the infrared energy given off by occupants as they move within the field-of-view. When occupancy is detected, a self-contained relay switches the connected lighting load on. The sensor is line powered and can switch line voltage. An internal timer, factory set at 15 seconds, keeps the lights on during brief periods of inactivity.

Initial Power Up (30 seconds warm-up)
The sensor's relay is shipped in a latched closed position so the lights will come on upon initial power-up. The lights contacted with sensor will keep on working during the 30 seconds warm-up period, andthe LED in the sensor will blink during this period. If the lights do not immediately turn on (initial installation only) the latching relay opened during shipment and will close after warm-up period is over.

Sensor Installation
  1. Put the threaded nippleof the sensor part A(with wires)into a half inch hole of the luminaries’ body or the electrical box and clockwise the lock-nut onto the threaded nipple. This whole installation process will be done by factory, if you purchase the fixture with sensor part A or the electrical box with sensor part A.(Fig.5A)
  2. Prepare the sensor part B(main sensor part)and make the sensor part A insert into sensor part B directly.(Fig.5B)

Sensor replacement
  1. Press down the two-sides buttons simultaneously, and extract out the main part of sensor switch.(Fig.4A and Fig.4B)
  2. Plug in the replaceable main part of sensor switch ,just need several seconds. No need to disassemble the screws of fixture, saving time and effort. 

Sensor Adjustment & Programming
Time Delay Knob
Turn the adjustment on the left “TEST” fully counter clockwise to the minimum setting (30 seconds) while fully clockwise to the maximum setting (30 minutes), verify by turning lights on with pushbutton.

Sensor Sensitivity RangeKnob
Default position:75% (Position 3)
Adjustable:50%(Position 1) to100%(Position 5)
The sensitivity adjustment is in the center and marked “SENSE”, Adjust the sensitivity setting to avoid unwanted detection such as hallway traffic or adjacent movement, Turing the setting counter clockwise will decrease sensitivity while turning it clockwise will increase it. Max sensitivity while turning it clockwise will increase it. Max sensitivity can be achieved by turning fully clockwise on Position 5

Ambient Light Level Knob
Default position:Daylight (Position 5)
This light level is in the right and marked ”LIGHT”, it used to detect if other light source such as sunlight, are enough to illuminate the space without turning on the lights, if use of Ambient light level is desired, please turn the adjustment knob counter clockwise, and push the button to make sure the sensor start to work, if use of the light level is not desired, please leave it on the maximum setting ( Position 5 ), This will allow the sensor to turn the light on and off regardless of ambient light conditions.

Troubleshooting
Lights 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.

Lights Will Not Turn OFF
Make sure no motion is occurring in the coverage area until the 15 seconds(factory set)time delay expires.
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 closely to an air conditioning or heating vent: Move the sensor or close the vent.
The line voltage has dropped: Perform the necessary tests to ensure the line voltage has not dropped beneath 100V.

Lights Turn OFF And ON Too Quickly
Sensor may be mounted too closely to an air conditioning or heating vent: Move the sensor to another location or close the vent.
Time delay set improperly:Refer toTime delay Adjustment
