4. Wiring

Wiring layout suggestion:
1. KNX bus wiring suggestion hand in hand to the end, star or tree wiring is not recommended to ensure the stability of signal transmission.
2. KNX bus wiring recommends KNX standard EIB shielded wire or Category 6 network cable; the length of the bus wiring is recommended not to exceed 400 meters, and the number of sensors connected to a bus is recommended not to exceed 12.
3. The number of sensors connected to a bus needs to fully consider the current load capacity of the power supply, which means the sum of the currents of all KNX devices (including sensors) shall not be greater than the load current of the KNX power supply.
5. Detection Range

6. Initialization
After routing the physical addresses and setting the channel parameters, follow these steps:
(1) Connect Bus interface;
(2) Set Bus and auxiliary power on (note: please make sure that the product has an auxiliary power supply, otherwise the device may not work properly);
(3) Press the programming switch of the product, and the LED light will turn red.
(4) Use the bus interface to download the physical address through the ETS software. The programming LED light is off to indicate that the physical address download is successfully completed.
(5) Download the application after setting the required application parameters.
(6) After downloading the application, the product goes into initialization. During initialization, the detection function is disabled. After 20S, the initialization is completed, and the product works normally.
Note: Please use the latest version of ETS 5 or 5.7.2. Please obtain the ETS engineering configuration file of this sensor from our sales staff.
7. Factory Default Setting
Detection Area: 100% Hold Time: 5S Indicator Light: open
