Failing Marmitek AD10


Hello,


I have made an X10 installation in my new apartment using mainly AD10's (28 modules) LD11(6 modules) and SW10 (16 modules) from Marmitek, as you will see in the attached picture.
Despite some problems in the beginning, the system is now running perfectly well.
The AD10s are used to run low intensity 12V power adapters driving LED lighting as well as florescent lights, appliances and water valves. The maximum current load is about 200W (being less than 1 AMP on 220V)
Ever since they entered in service, the AD10s have been failing gradually, so far 14 units have failed at the rate of 1 every 2 weeks. The last module failed minutes ago -what made me rush to write this blog-, it is the one driving two fluorescent lights of 40W each installed in my walking closet!
The faulty modules start by failing intermittently until they become totally unresponsive to X10 signals and even to manual operation from the integrated button.

Although the dealer has been replacing the modules. They were not able helping me identify the reason behind those repetitive failures, claiming that their units have no structural damage and therefore they cannot further investigate my problem.

Non of the LD11 or the SW10 have failed, both the modules are ok so far (fingers crossed)

Please let me know if any of you have faced similar issues with the AD10. Apart from few posts on the internet claiming failures of AD10's, I was not being able to find related information. I'm really worried of what will happen when the warranty expires!
I would also like to know if similar better quality products exist?


Thank you

  3. Hello, just days ago (aug 2010) I installed a AD10. For a few days everything worked just fine, but now the relais is switched on continually and is not responding to the command anymore and also the manual switch up front is not functioning.
    It seems to me a problem with a certain production period. I bought the relais already in 2008,but not installed. Otherwise it is probable a design failure.
    I hope a new one will solve the problem.

  4. I thought I was alone but I can see that the same problem happened also to other people. I bought 4 ad10 and gradually all of them started to failure. some of them keep in on position some others (most) on off. Even if I work on the manual switch. I believe is a matter of design or is there any solution?

  5. Hello guys

    I finally discovered the issue causing the problem: it seems that the AD10 modules won't tolerate an ambient temperature higher than 25 degrees Celsius. So if u manage to keep them cool, they will work for years.
    I changed more than 30 modules before I discovered this. You will be happy to know that ever since I made modifications to the electrical cabinet more than a year ago, allowing more air to flow inside, not a single module has failed.
    I have even installed a thermometer recording the high and low temperatures
    So bottom rule: keep them cool!

  6. I bought 6 modules 2 years ago to install them in a house ampliation. Now I have the same problem than you, but I don't know why.
    To give more data. My temperature place isn't more than 25ÂșC (they are in a brick wall inside of a cold place).
    They start to work when I disconnect the load (the fluorescent lights or the pump rele-contactor).

  7. JC. I might be late in replying to u but just in case u didn't find a solution do answer the below question: what do u mean 'their have the same problem then' are they simply not responding to the x10 commands or is the switch on them that is not working?

  8. "They aren't responding to the manual push". Last June I changed the wrong devices by new ones.
    Last September one of the old ones switch on alone (and it was impossible to switch off by manual commands).
    Yesterday another one (a new one I install to replace one of the fault one on June) didn't switch on to push the manual switch.
    All of them are from 07XXX and 08XXX lots.
    Marmitek has told me today I have to buy and install new ones from 10XXX series or later.
    I'm thinking to leave my X10 project (the technology and the supplier are unreliable).

  9. JC,

    All of the AD10s I have are of the older batch 07XXX and ever since I have installed a special ventilation to the cabinet, non has failed.
    Although the ambient temperature in your home is lower than 25, it might not be the case inside the compartment in the brick wall. (especially if u have dimmers installed). According to what you said, I believe that Marmitek made some modifications to the AD10 making it less vulnerable to heat. Migrating to another system might be also a good idea provided you can make the extra in-wall wiring.
    Good luck

  10. Thank you for your answer. This evening the AD10 controlling the swimming pool pump has fault too (it's the second one too). In this case, I can disconnect the electrical charge (because the AD10 controls a DIN contactor and it has a switch on it), and when I do the AD10 works perfectly (empty). When I reconnect the charge it fails everytime.

  11. After a lot of contacts with Marmitek support and sales deparment about my (now) 5 fault AD10 devices. I knew my AD10 aren't from Marmitek. They are made by BMB Electronics (another the Nederlander Company), and my supplier sold them to me as they were genuine Marmitek ones.
    I don't know if this was the problem (they are low quality ones), but they externaly are identical to marmitek ones, and the lots number are Marmitek lot numbers.
    ¿Do you know this company or these devices brand?

  12. Hello JC,

    Marmitek, Powerhouse, BMB, Letsautomate... (the list is long) All those products are manufactured in china by the same EMS/Manufacturer and sold in Europe and the rest of the world by respective resellers.
    The above explains why the same item from different brands carry the same model, part and batch numbers.
    If you bought your product from BMB then you should contact BMB for the warranty.
    As for your earlier post, the AD10 operates like a relay so its operation shouldn't be influenced by the load connected to it. The only thing I can think of in your case is that the load itself -when operational- is causing interference on the AC line which causes the X10 system to become unresponsive. In this particular case, only a line filter could solve your problem.

    Good luck
