KPC failure KRC4 Compact

    Hello -


    Started getting texts that our KR6 Agilus was down last night. Came in to find that the teach pendant it was repeatedly pinging the KPC with no response. The external monitor was also down. Tested several more monitors and cables before pulling the controller out of the rack. It did have a fair amount of MDF dust built up inside. However, the controller will boot up with fans running. The NIC leds are lit, but internal EK1100 shows there is no communication with KPC. Drive tested ok. Pulled it to clone. Is it common for these Fujitsu mainboards to fail?


    Thanks

    It's quite rare for these motherboards to fail (aside from a time period several years ago where every motherboard manufacturer on Earth got hit by a tsunami of bad Chinese capacitors), unless they've been mistreated. If the controller has "large amounts of dust" inside, then this controller has not been cared for properly, or not been properly protected.


    If there is no signal on the DVI port when power is applied to the controller, that strongly implies the motherboard is dead -- even if the SSD or RAM were bad, the BIOS POST should still appear, at minimum.

    it is common for anything to fail when exposed to wrong environment. why would there be any dust inside controller?

    Thanks to all for responses. ATX power supply just tested clear so it looks like the board has to be swapped out. Dust is unavoidable around here as we do a lot of milling. Controller is mounted underneath the robot on a mobile cart. The external coarse fan filters just weren't enough. Four years was a decent run, but the failure was most likely avoidable. Will have to modify cart so it's easier to pull out controller for proper cleaning in the future.

    KRC4 compact is IP20 rated.[/size][size=2]KRC4 small size (type 1) is same hardware but in IP54 enclosure. [/size][size=small]


    [/size][size=2]So small size controller would be much better fit for this application.[/size][size=small]
    [/size][size=2]Alternatively compact can be placed into another enclosure with forced air circulation and suitable filter.[/size][size=small]
