A 60-second start-up period occurs during initial installation and after a power failure of 5 minutes or more. After applying power to the
sensor wait at least 60 seconds for the sensor to begin detecting occupancy and the load to turn ON. It may turn ON during the start-up
period, depending on the state of the relay when power was off.
• If the sensor detects occupancy during the start-up, when the load turns ON it stays ON as long as the sensor continues to detect
motion, plus the Time Delay.
• If no occupancy is detected during the 60-second start-up, the load may come on anyway during the start-up. If no occupancy is
detected by the time the start-up is complete, the relay opens and the load turns OFF.
If you suspect improper operation, review the Start-Up information. After start-up, the sensor will open or close the relay to correspond to
the occupancy status of the area. When power to the sensor is lost, the relay(s) close, turning on the load if the load still has power.
To quickly test the unit, set the time delay to minimum. Wait for the start-up period to end. Move out of the sensor's view. Lights should
turn OFF after 15 seconds. Move into the sensor's view. The sensor's Red LED should blink and the lights should turn ON.
Red LED on power module does not blink:
Check sensor wire connections. Verify the neutral wire is tightly secured.
Red LED blinks but lights do not turn ON:
1. Make sure that power to the sensor has been ON continuously for at least one minute, then
a. Turn OFF power to the sensor. The relay will close.
b. Turn ON power to the sensor. The load should come ON. If not, continue with step 2.
2. Check power connections to the light fixture.
3. Check all sensor wire connections. Verify the load wire is tightly secured.
4. Make sure the sensor is not continuously triggered (LED Flashing) during the time delay duration.
Lights will not turn OFF:
1. If there is no motion from people or equipment in the sensor's view but the red LED blinks, look for any nearby source of infrared
energy (heat) in motion, such as turbulent air from a heating or cooling supply, or other sources such as heat from the fluorescent
lamps in the fixture.
• Mount the sensor so that it's lens is below the edge of the fixture and does not directly view the lamps.
• Divert the air supply away from the sensor, or move the sensor.
2. Verify time delay set in switches 3-7. The time delay can be set from 15 seconds to 30 minutes. Ensure that the time delay is set to
the desired delay and that there is no movement within the sensor's view for that time period.
3. Check PIR and Light Level Override DIP switch settings. If all control functions are overridden the load stays ON.
4. Check sensor wire connections. Verify load and neutral wires are secure.
