    Hey Buddy, You do what you think is best, If it saves me replacing the unit im up for it, and even if it turns out to be dead all we can do is try.

  2. Small update.

    Here is the Lenze 534 Controller before repair.



    And again after repair.


    Looks much better, but not yet tested.

    damn you've spotted it, ......lol.....

    seriously though, behind the middle pot and the add in card there looks like a fuse (small reddish brown cylinder), which has been changed for a capacitor. I may be wrong on the fuse but it looks like one.

  6. Here is the list of parts that I have replaced.

    T1 - 2x15VAC 1.8VA Transformer.
    C2 - 470uf 35v.
    C4 - 470uf 35v.
    C5 - 4.7uf 63v.
    C6 - 47uf 35v.
    C7 - .47uf (470nF) 100v.

  7. But does it work??? Have you tried powering it up and seeing if you get reasonable volts in the obvious places?

  8. I have tested it as far as I can without having the DC motor to test it with.

    Will know more once Ricardoco gets it back middle of next week, and connects it up.

    Time to replace with new...
    Maybe the Controller needs to be set up again as per the manual. (When i got mine in the begining it was pulsing) i tuned the pots as per the manual and it was fine for 2 yrs...

    i just had a mate look at the photo and he says although it looks like a fuse, it also looks like a cap. If it says C? on the board then it will be a capacitor.
