  If the lights don't turn on when you enter the room, you should: * Check that the circuit breaker has been turned back on. * Check all sensor and power pack wire connections. * Check for 24VDC input to the sensor between the red and black low voltage wires. If 24VDC is present, replace the sensor. If 24VDC is not present, check the high voltage connections to the power pack. If high voltage connections are good and high voltage is present, replace the power pack.

  If the lights do not turn off automatically, try the following steps: 1. Check all sensor and power pack wire connections. 2. Disconnect the power pack blue wire. If the lights do not turn off, check the power pack wiring. If the lights turn off, the problem may be the sensor or wiring between the sensor and power pack. 3. Reconnect the blue wire. 4. Turn sensitivity and time delay to minimum, and allow the sensor to time out. If the lights turn off, the sensor is working properly – adjust sensitivity and time delay for the sensor. If the lights do not turn off, check the wiring between the sensor and power pack. If the wiring is correct, replace the sensor.

What to do if red and green LEDs flash on LEGRAND Watt Stopper DT-305?

  If both the red and green LEDs are flashing, take these steps: * Check all sensor and power pack connections. * If a Light Level is connected, verify Light Level functionality is required and press and hold the Light Level button for 5 seconds to make sure it is not holding OFF the load. If Light Level functionality is not required, reference the wire diagrams for proper wire connections. * Check for 24VDC at the power pack blue and black wire connections to sensor while sensor is active. If there is no voltage, replace the sensor. If there is voltage, check for 24VDC between the blue and black wire at the power pack. If 24VDC is present and the relay is not closing, replace the power pack. If 24VDC is not present, check for a break in the low voltage wiring.

What does it mean if the green LED is on continuously on LEGRAND Watt Stopper DT-305?

  If the green LED is continuously on, check the ultrasonic sensitivity trimpot. The fully counterclockwise position is the override for the sensor. Turn the trimpot clockwise until the LED flashes only when movement occurs in the desired coverage area.

Why is the red LED not flashing on my LEGRAND Accessories?
- S
  Stephanie WalkerAug 22, 2025
  If the red LED is not flashing, it could be due to a warm-up period of 30 to 60 seconds after power is initially applied to the sensor before the LED becomes active. Also, ensure the PIR sensitivity is set to 100% by verifying that DIP switch #8 is in the “on” position.
