LEGRAND HB3 B Serie Instrucciones De Instalación página 4

When the power module is installed and power is connected, the load comes ON and stays ON for 50 seconds. This warm-up period
only occurs during installation or after a power failure of 5 minutes or more.
• If the sensor detects occupancy during the warm-up, the lights stay ON as long as it continues to detect motion, plus the Time
Delay.
• If no occupancy is detected during the warm-up, the light turns OFF after the initial 50 second warm-up period.
During the sensor warm-up period, which can last up to a minute after power is applied to the power module (or after a power outage of
5 minutes or more), the load can be either ON or OFF, depending on the status of the relay before the sensor was powered down. After
warm-up, the sensor will open or close the relay to correspond to the occupancy status of the room.
To quickly test the unit, turn the time delay to minimum. Wait for the warm-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 red and black wires are 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.
b. Check control wire (blue or violet) connection.
c. Turn ON power to the sensor.
d. The load should come ON. If not, continue with step 2.
2. Check power connections to the light fixture.
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 IR energy
in motion, such as turbulent air from a heating or cooling supply, or other sources. Divert the air supply away from the sensor, or
move the sensor.
2. Verify time delay. 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 DIP switch 8 setting. If it is ON, it overrides the PIR function and keeps the load ON.
4. Check sensor wire connections. Verify control wire (blue or violet) is secure
