    SMARDT CHILLER OIL FREE CENTRIFUGAL CONTROL

    good afternoon.
    refrigeration mechanics.
    I have a problem, and I need help.
    Putting it in context, it is the December holiday season, I am in a tropical coastal area, it is when the greatest refrigeration load is needed.
    I have two SMARDT OIL FREE chilled water generating units, each with 2 turbocor tt400 compressors.
    I only have one computer working, the other damaged the kiltech control cpu, the unit was already bought, it comes from Canada, because of the distance and customs, I think it will be late. I've been trying to start the computer manually.
    The equipment in operation has an axiomtek 201 cpu with 4 ports for communications, 2 of them used for kiltech control and compressors.
    Some of you will know if the module will support connecting 2 more communications, in this case it would be the other unit.
    I have installed fast action to clone the system and adapt it to a personal cpu, we continue in the attempt.
    I do not have access to access code.
    If you can help me I would be very grateful.
    Greetings colleagues from the refrigeration and air conditioning

    Do you have Gen 3 or 4 controls. In either case you need to get that controller or retrofit to another controller.

    It is generation IV, after many tests and attempts I managed to keep the 2 chillers on, one in standard mode and the other using the killtech cpu. monitoring compressors with danfoss application for compressors. I do not have the access code and it is programmed to only 40% of maximum demand.

    Is it the Windows computer that went bad or the actual chiller controller

    I'm wondering the same thing. Just an FYI, there is a fuse on the Kiltech right where the 24VDC power supply plugs in.

    OK

    I have the same chillers

    try code 1234 or 4321

    That should allow you to change the demand limiting
