    Hi All,

    Just reaching out to see if anyone else has experienced a similar issue with the new Dali Gateway.

    I have residence with 30+ fittings that I've configured using Rapix and Cbus commissioner.
    of the these fitting there is 5 units that exhibit the following behavior. No other fitting have an issue.

    Drivers are TCI 127492
    1. Lights are addressed using the Cbus Commissioner Application. (also addressed using Rapix software to eliminate software as the issue).
    2. Lights all respond to switching operations and dimming operations flawlessly.
    3. After around 15-20 minutes after addressing, the fittings no longer respond to any commands switching or dimming.
    4. At random intervals the fitting may come back online but flickering is a common occurrence. (Flickering indicates to me a possible incompatibility between the LED chipset and the Driver)
    5. To get full control back over the lights the Controller Broadcast function is used. This appears to wake the units up or reset them allowing the units to be used again for approximately 15 minutes.
    6. Lights return to not operating. This cycle continues indefinitely.
    I have spoken to both the manufacture and SE now and got the obligatory finger pointing.
    I've been using Dali for year and the basic debugging has been done.

    As the gateway is new and the software equally so, I'm less inclined to state it isn't these elements.

    I guess I'm just putting this out there in the hope someone else spots something I'm missing, or if this is occurring in other installs people don't feel too isolated.

    Any comments or thoughts would be greatly appreciated.

    Have you physically swapped a faulty unit and good ones location to confirm it not a wiring issue

    Are the DALI drivers reporting any errors when inspected with Rapix or Masterconfigurator?

    I'd suggest the following steps:

    1. Go to 2 fittings, one that works OK, and 1 that does not.
    2. Swap the DRIVERS ONLY.
    3. After the physical swap, then swap their short addresses, so they are set for the right address in the right place. I also suggest you do this using RAPIX in order to eliminate any other possible thing going on. Make sure the C-Bus gateway is DISCONNECTED when you do that.
    (why all this fuss? You want to change ONE THING ONLY)

    What happens?

    If the problem stays at the lamp -> its a driver / lamp problem (driver not working happily with the lamp).

    If the problem MOVES with the driver -> the driver is probably dodgy.

    As the number of DALI drivers in the world has increased and prices have come down, so has quality. Bad drivers are certainly a known thing. This is not to say it's a bad driver - TCI are well known and generally well respected, but this does not make them perfect.

    On the score of "If you had to recommend a DALI driver, which manufacturer would you recommend?" The answers is NONE OF THEM - because I just don't know. The only ones I recommend are our own, and we sell only through some very specialised channels - so I can't sell to anyone who wants one.

    Disclaimer: Have a lot to do with RAPIX these days.
