    Given your errors are showing up on "INIT Test", code translation will direct you to checking incoming voltage. Specifically, it reads,"Power part test cannot be carried out,conditions for testing not fulfilled (In most cases wrong supply voltage). Press does not start running." Suggest you verify 3 phase power, and check secondary voltage transformer.

    hi sir watch check the MSK, there may be corrosion or a component to perform. For the KVT I think it is normal since it does not give any information.
