    What voltages are we talking about?

    Is there a code # with the trouble code? What does the book say?

    1. Is the voltage actually low?

    2. Is the low current setpoint correct?

    3. Is the current transformer working?

    4. Is the compressor load speed correct?

    The book says that "Power supply discon- nected, blown fuse, wiring error, contact deenergized, faulty current toroid high pressure switch trip"
    I cannot understand the last one ????

    If you've got current- swap the current transformer from the other system. If the fault moves- change the current transformer
