  • waking up chassis

    Hey colleagues!

    What's your opinion about waking up your sparechassis sometimes?
    What happens when a chassis lays for 10 years on a shelf and comes to life?
    Heard that some electronics for example capacitors don't like being unused for so long.
    Are there other components, like relays, have problems with this?

    thank you very much

    Re: waking up chassis

    Not a problem here... out spare chassis get rotated on to the machines when one needs to come off for new contactor contacts, etc... It's nice having a couple spares to do that... don't have to worry about getting on chassis ASAP because it needs contacts. Put a spare on, then rebuild the contacts, inspect the chassis, and clean it at your leisure... then put the rebuilt and cleaned chassis into rotation as the next 'spare'.

      That's the method we use here too

        Capacitors are the weak link, but not very often. If you are using Omega Teks, that board dosn't care anyway! Relays, well there is a "potential" problem - a lot of centers are using the originals (1960's era) &amp; they can become flakey after, oh, 40 years. I know it is lil pricey, but new relays will say you a lot of potential headaches. Heck, after 40 years of "use" I get a lil flakey too!

        I've had enough of hope & chains.

          I rebuilt all our spares, we now have 6. 3 for each side. They do get use in rotation when new contacts or something is needed, the spare goes on but I'm a stickler for chassis's staying on the same machine so when the original is done it goes back and the spare comes off. Next time one needs work I'll use a different spare then the 1st time, and so on and so forth. Before I rebuilt them they sat for at least 6 years all with pretty minor problems and once they were repaired they all ran like champs
          All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/
