    Description and Adjusting Instructions Additional Module "CUN1" For Voltage Regulator "Cosimat N"

    Uploaded by

    TariqMaqsood
    The document provides instructions for connecting, adjusting, and operating an additional module called CUN1 that works with a voltage regulator called COSIMAT N. The CUN1 allows automatic balancing of an alternator's voltage to match the mains voltage. It measures the mains voltage and adjusts the alternator voltage using trimmer pots. LEDs indicate when the CUN1 is activated and released. Wiring diagrams and adjustment procedures are provided.

    in the instant of synchronization. US 500 ⇔ US 0 = 250 VAC up to 500 VAC
    US 250 ⇔ US 0 = 90 VAC up to 250 VAC
    By using module "CUN1" balancing of the alternator voltage
    can be automated. By adjusting once with the two trimmers "Coarse" and
    "Fine", the alternator voltage is adjusted to the mains
    The mains voltage is measured and the rated value of the voltage.
    alternator voltage will be adjusted automatically to match the
    mains voltage by "CUN1".

    The voltage balance must be released by a potential free 14
