    Hi sir;
    Normally this contactor work(c0il) with 22oVca, however you must check in the schematic diagrams.

    2) Please measure in the PLC, in the output, and see if there are some Fuses or Circuit Breaker open or triggers , some Leds will be Lit( if the contactor coil is o.k) or OFF( If the contactor is faulty):

    3) Look for the contacts of the contactors, if there dirty, or worn, and replace it, see if there are some Loose wires, and tigh very well, and clean it, with Spray electrical contacts, very Powerful.
