Testing
Presence Detection
- Power up the sensor. The load should come on immediately.
- Press the Lux button quickly 5 times to set once to set it to minimum.
- Vacate the room or remain very still and wait for the load to switch off (this should take less than 2 minutes).
- Enter the room or make some movement and check that the load switches on.
Programming with push buttons
To find the current Lux and Time settings
Press and hold the Lux button for more than 3 seconds. The number of LED flashes indicates the setting:
| # Flashes | Light |
|---|---|
| 1 | Minimum |
| 2 – 4 | Increasing level |
| 5 | Maximum (always on) |
Press and hold the Time button for more than 3 seconds. The number of LED flashes indicates the setting:
| # Flashes | Time |
|---|---|
| 1 | 10 seconds |
| 2 | 5 minutes |
| 3 | 10 minutes |
| 4 | 20 minutes |
| 5 | 30 minutes |
To switch lights on when presence detected depending on natural light level
- Wait until the level of daylight is just low enough that lighting is needed.
- Press the Lux button once to set it to minimum.
- If the lights don’t come on, press the Lux button twice. Repeat this with 3 or 4 presses until the lights come on.
- Pressing the button 5 times sets the level to maximum and the lights will always come on with occupancy.
To lock the programmed settings
Press and hold either button or for more than 10 seconds to toggle between
lock and unlock. This locks the sensor if the LED lights up while pressing the
button. This unlocks the sensor if the LED doesn’t light up but flashes once
after 10 seconds.
