    Hello


    I am pulling my hair out, hopefully you guys can help me out.


    I purchased a 12 Channel relay(L5512RVF)


    I am trying to integrate it into my existing network but every time I connect it to the cbus network the whole network goes down. The cbus indicator goes out as soon as plug in the cbus network even when this relay is only connected to 1 of the existing dimmer unit


    I have used the Cbus calculator to see if I require a power supply but as I expected I don’t

    Enable one burden only



    Fyi: I also have a SHAC unit which is not available in the calculator


    I have but the relay into super learning mode and disabled the clock and burden as the existing units will supply the necessary signalling.



    Can you give me any advice in resolving this issue?

    Check the voltage by actually measuring it :)

    Do it first with the device disconnected. then again with it connected.

    Is this a new device or second hand? It is possible for a cbus unit to develop a fault that will take out the whole network, but this is rare, and certainly not if it is a new device.

    Does it have an inbuilt power supply?

    Have you connected the 240V to it?

    And, of course, recheck all your cabling.
